A “bright” button 55 and a “dark” button 56 for instructing to increase or decrease the dimming rate, and an instruction for toning from “bulb color” to “daylight color” or “daylight color” to “bulb color” "Cold color" button 61, "Warm color" button 63, "Brightness plus" button 64, "Favorite 1" button 65, "Favorite 2" button 72, "Before sleep" button 66, and "Register favorite" 1 ”button 71,“ favorite registration 2 ”button 73,“ answering timer ”button 67,“ off timer ”button 74,“ on timer ”button 75,“ my home style ”button 62, and numerical values. "UP" button 57A and "DOWN" button 57B, "Environment registration" button 69, "Channel switching" button 77, "Time setting" button 68, and "Reset" button 78 Is provided.

  The CPU 86 of the remote controller 50 receives an input instruction of each button in the operation SW 88 via the SW input unit 83 and instructs the signal transmission unit 84 to output a transmission signal corresponding to each button. In response to an instruction from the CPU 86, the signal transmission unit 84 outputs a transmission signal corresponding to each button to the illumination device 1 through the infrared projection unit 87 as an infrared signal. The infrared light receiving unit 41 of the illumination device 1 receives the infrared signal projected from the infrared light projecting unit 87 of the remote controller 50. The infrared light receiving unit 41 photoelectrically converts the received infrared signal. Then, the signal receiving unit 25 outputs a transmission signal instructed from the remote controller 50 obtained by photoelectric conversion to the CPU 22. With this operation, the CPU 22 executes an operation according to an input instruction from the remote controller 50.

  Specifically, as described above, when the user presses the “bright” button 55 or the “dark” button 56, the CPU 22 adjusts the dimming rate according to the light emission of the LED modules 31 and 32 in the illumination unit 30.

  For example, when the “dark” button 56 is pressed in a state where the light is all light (dimming rate 100%), the state changes from “full light” → “half light” → “light”, and the state (light control rate 30). %) Changes as “light” → “half light” → “full light” as the “bright” button 55 is pressed.

  Further, as described above, when the user presses the “cold color” button 61 or the “warm color” button 63, the CPU 22 adjusts the color tone according to the light emission of the LED modules 31 and 32 in the illumination unit 30. For example, “daylight color” → “daylight white” → “warm white” → “bulb color” as the “warm color” button 63 is pressed in the state of “daylight color” which is all daylight color lights (dimming rate 100%). As the “cold color” button 61 is pressed in this state (light bulb color), “bulb color” → “warm white” → “day white” → “daylight color” changes.

  In the present example, the portable remote controller 50 has been described. However, the present invention is not limited to this, and a fixed remote controller provided on the wall surface may be used. Further, the remote controller may be provided as a part of the interface unit 40 of the lighting device 1. In that case, it is also possible to adopt a configuration in which the instruction signal from the operation SW is directly transmitted using a signal line instead of transmitting the operation SW signal by an infrared signal. In addition, transmission / reception of signals is not limited to infrared rays, and wireless or the like may be used.

  In this example, a method of executing various modes of the lighting device 1 in accordance with an input instruction by a button operation via the remote controller 50 will be described. However, the input method is not limited to this, and illumination is performed by other methods, for example, voice input. An input instruction may be given to the apparatus 1.

  FIG. 7 is a diagram (part 1) illustrating a main flow of lighting apparatus 1 according to the embodiment of the present invention.

  The main flow starts when the power switch is turned on, and is executed when the CPU 22 reads a program stored in the memory 29.

  When the power switch is turned on and the flow is started, referring to FIG. 7, first, the CPU 22 instructs the PWM control circuit 23 to perform lighting control in the illumination unit 39 (step S1). Thereby, the light from the illumination unit 30 is irradiated into the room. In step S1, the CPU 22 instructs the lighting control with the light control rate and the color tone set in the mode when processing in each mode to be described later is performed. Otherwise, that is, processing in each mode described later is not performed, and is set in advance as normal lighting control immediately after the power switch is turned on or when the light environment control mode described later ends. The lighting control using the LED module 31 to irradiate daylight light at a dimming rate of 100% is instructed.

  Next, the CPU 22 determines whether or not there is an input instruction (step S2). If CPU 22 determines in step S2 that there is an input instruction (YES in step S2), CPU 22 next determines whether or not a lighting adjustment instruction is input (step S3). Specifically, an input instruction of a “bright” button 55 or a “dark” button 56 for adjusting the light control rate provided in the remote controller 50 or a “cold” button 61 or “warm color” for adjusting the color tone. It is determined whether or not there is an instruction to input the button 63.

  If the CPU 22 determines that a lighting adjustment instruction has been input (YES in step S3), the CPU 22 shifts to a lighting adjustment mode (step S4). Processing in the lighting adjustment mode will be described later.

  On the other hand, when it is determined that the lighting adjustment instruction has not been input (NO in step S3), the CPU 22 determines whether there has been a light environment control instruction input (step S5). Specifically, the CPU 22 determines whether there is an input instruction of the “light environment control” button 58 provided on the remote controller 50.

  If the CPU 22 determines that an instruction for light environment control has been input (YES in step S5), it shifts to the light environment control mode (step S6). The processing in the light environment control mode will be described later.

  On the other hand, if the CPU 22 determines that there is no light environment control instruction input (NO in step S5), it next determines whether or not there is an instruction input for my home setting (step S7).

  Specifically, the CPU 22 determines whether or not there is an input instruction of the “my home style” setting button 62 provided on the remote controller 50.

  When CPU 22 determines that there has been an instruction input for my home setting (YES in step S7), it shifts to my home setting mode (step S8). The processing in my home setting mode will be described later.

  On the other hand, when CPU 22 determines that there is no instruction input for my home setting (NO in step S7), CPU 22 next determines whether there is an instruction input for eco lighting (step S9). Specifically, the CPU 22 determines whether or not there is an input instruction of the “eco light” button 60 provided on the remote controller 50.

  If the CPU 22 determines that there has been an eco lighting instruction input (YES in step S9), the CPU 22 shifts to the eco lighting mode (step S10). The process of the eco lighting mode will be described later.

  If it is determined in step S9 that there is no eco lighting instruction input (NO in step S9), the process proceeds to "A".

  FIG. 8 is a diagram (part 2) illustrating a main flow of lighting apparatus 1 according to the embodiment of the present invention.

  Referring to FIG. 8, if it is determined in step S9 that there has been no eco lighting instruction input (NO in step S9), it is next determined whether or not an illuminance sensor instruction input has been received (step S11). Specifically, the CPU 22 determines whether there is an input instruction of the “illuminance sensor” button 70 provided on the remote controller 50.

  If the CPU 22 determines that an instruction input from the illuminance sensor has been received (YES in step S11), the CPU 22 shifts to the illuminance sensor mode (step S12). Processing in the illuminance sensor mode will be described later.

  On the other hand, when CPU 22 determines that there is no instruction input from the illuminance sensor (NO in step S11), CPU 22 next determines whether there is a timer instruction input (step S13).

  Specifically, the CPU 22 determines whether there is input of information in accordance with the operation of the absence timer 67, the turn-off timer 74, and the on timer 75 regarding the timer provided in the remote controller 50.

  When CPU 22 determines that there is a timer instruction input (YES in step S13), it shifts to the timer mode (step S14). The timer mode process will be described later.

  On the other hand, when CPU 22 determines that there is no instruction input from the timer (NO in step S13), CPU 22 next determines whether there is an instruction input for brightness plus mode (step S15). Specifically, the CPU 22 determines whether there is an input instruction of the “brightness plus” button 64 provided on the remote controller 50.

  If the CPU 22 determines that an instruction to enter the brightness plus mode has been received (YES in step S15), the CPU 22 proceeds to the brightness plus mode (step S16). The process in the brightness plus mode will be described later.

  If it is determined in step S15 that no instruction for brightness plus mode has been input (NO in step S15), it is then determined whether or not an instruction for favorites registration has been input (step S17).

  Specifically, the CPU 22 determines whether there is an input instruction for either the “favorite registration 1” button 71 or the “favorite registration 2” button 73 provided on the remote controller 50.

  If the CPU 22 determines that an instruction for favorite registration has been input (YES in step S17), the CPU 22 shifts to the favorite registration mode (step S16). The processing in the favorite registration mode will be described later.

  On the other hand, if the CPU 22 determines that there has been no instruction input for favorite registration (NO in step S17), it executes other processing (step S19). Then, the process proceeds to “B”. That is, the process returns to step S1 in FIG.

<Lighting adjustment mode>
In the lighting adjustment mode, in response to a dimming and / or toning operation instruction of the remote controller 50 from the user, the light emission state of the LED modules 31 and 32 in the illumination unit 30 is controlled and adjusted to the desired dimming and toning. It is a mode to do.

  FIG. 9 is a flowchart illustrating processing in the lighting adjustment mode according to the embodiment of the present invention.

  This flow is executed when the CPU 22 reads a program stored in the memory 29.

  Referring to FIG. 9, first, CPU 22 determines whether or not it is an instruction to input a dimming button (step S <b> 100). In this example, the dimming buttons are a “bright” button 55 and a “dark” button 56, for example. If it is determined that the input instruction is not for the light control button of the “bright” button 55 or the “dark” button 56 (NO in step S100), the process proceeds to step S110.

  On the other hand, if the CPU 22 determines that the input instruction is the “brighter” button 55 or the “darker” button 56 (YES in step S100), then whether the pressed button is the “brighter” button 55 or not. Whether it is the “darken” button 56 is identified (step S102).

  If the pressed button is “bright” button 55 (YES in step S102), CPU 22 increases the current dimming rate by a predetermined dimming rate (step S104). If the pressed button is “dark” button 56 (NO in step S102), CPU 22 decreases the current dimming rate by a predetermined dimming rate (step S106). Then, the process ends (return). That is, the process returns again to step S2.

  Specifically, when the user presses the “dark” button 56 in a fully lit state (dimming rate 100%), the lamp is set to a half-light (dimming rate 50%). When the “dark” button 56 is pressed in a state where the lamp is half-lit (dimming rate 50%), the light is set to light (dimming rate 30%). Further, when the user presses the “bright” button 55 in the state of the low light (light control rate 30%), the light is set to half light (light control rate 50%). When the “bright” button 55 is pressed in the state of a half-light (dimming rate 50%), it is set to full lighting (dimming rate 100%).

  In step S110, if the CPU 22 determines that the input instruction is not for the “bright” button 55 or the “dark” button 56 (NO in step S100), the CPU 22 determines that the input instruction is for the toning button. In this example, the toning buttons are a “warm color” button 63 and a “cold color” button 61 as an example.

  If the CPU 22 determines that it is not an instruction to input the dimming button, it next determines whether the pressed button is the “warm color” button 63 or the “cold color” button 61 (step S112). When the pressed button is “warm color” button 63 (YES in step S112), CPU 22 maintains the dimming rate and maintains the dimming rate of the current color tone on the light bulb side in advance. The daylight color side dimming rate is decreased by a predetermined dimming rate (step S114). When the pressed button is “cold color” button 61 (NO in step S112), CPU 22 maintains the dimming rate and maintains the dimming rate of the current color tone on the light bulb side in advance. The daylight color side dimming rate is increased by a predetermined dimming rate (step S116). Then, the process ends (return). That is, the process returns to step S2 in FIG.

  Specifically, when the user presses the “warm color” button 63 in the “daylight color” state where the daylight color is all the lights (light control rate 100%), “daylight white” is set. When the “warm color” button 63 is pressed in the “day white” state, “warm white” is set. When the “warm color” button 63 is pressed in the “warm white” state, “bulb color” is set. When the user presses the “cold color” button 61 in the “bulb color” state, “warm white” is set. When the “cold color” button 61 is pressed in the “warm white” state, “day white” is set. When the “cold color” button 61 is pressed in the “day white” state, “daylight color” is set.

  In the above description, the case where the color tone changes in four stages according to the input instruction of the toning button of the “warm color” button 63 or the “cold color” button 61 has been described. However, the color tone can be finely adjusted by using more than one stage. Is possible.

  On the other hand, regarding the change in color tone, there is a difference in how the human eye perceives the change in the color temperature of light depending on the color temperature. Specifically, there is a tendency to feel the change more sharply as the color temperature becomes lower. Therefore, when changing the color tone between “bulb color” and “daylight color”, if the color temperature is simply changed linearly, the color tone of the “bulb color” side, in particular, depends on the characteristics of the human eye. When changing, there is a possibility of feeling a sudden change.

  FIG. 10 is a diagram illustrating a change in color tone according to the embodiment of the present invention.

  Referring to FIG. 10, here, as an example, a case is shown in which the color tone is changed in ten steps as a transition from “bulb color” having a low color temperature to “daylight color” having a high color temperature.

  Specifically, the color temperature difference is set to gradually increase as the color of the light bulb changes from a low color temperature to a high daylight color.

  In this example, as an example, in order to make the user feel that the color tone of 10 steps changes at an equal rate between the “bulb color” of the color temperature 2974K and the “daylight color” of the color temperature 5605K. The color temperature is set to be adjusted stepwise at an equal ratio between the ten steps.

  Assuming that the color temperature of the “bulb color” is 2974K and the color temperature of the “daylight color” is 5605K, the ratio r when the color tone is changed stepwise is calculated as follows.

Then, the dimming ratios of “daylight color” and “bulb color” are adjusted according to the calculated color temperatures.

  As a result, the dimming rate of “daylight color” and “bulb color” is set so that the color temperature difference gradually increases as the color temperature changes gradually from the low color temperature bulb color to the high color temperature daylight color. Therefore, it is possible to make the user feel that the rate of change in the color tone that changes with time is uniform, and the user can adjust the color tone to his / her favorite color without feeling uncomfortable.

  In this example, a case has been described in which the color temperatures between the 10 stages are set so as to change stepwise at an equal ratio (equal ratio). However, the present invention is not limited to this, and other methods are used. It is also possible. For example, the reverse color temperature that is the reciprocal of the color temperature may be used. Specifically, the value of mired obtained by multiplying the reciprocal of the value in Kelvin (K) by 1,000,000 is calculated for each of “daylight color” and “bulb color”, and the intervals between them are equally spaced. Set as follows. It is also possible to return to Kelvin (K) and set the dimming rates of “daylight color” and “bulb color”. In addition, although the case where the value multiplied by 1 million was used was described, it is not particularly limited to this, and the value may be set without being multiplied by 1 million.

  In the present example, the case where two types of color tone having different color temperatures of “daylight color” and “bulb color” are changed in stages has been described. However, the present invention is not limited to two types, and more than one type of color temperature may be used. You may make it change a color tone in steps using different LED.

  Further, here, a case has been described in which it is possible to change the tone in ten steps according to the input instruction of the “warm” button 63 or the “cold” button 61, but the number of steps is particularly limited. It is not a thing and can be set arbitrarily.

  Further, the above method may be adopted instead of the graph of FIG. 14 in another mode, for example, the light environment control mode described later.

<Light environment control mode>
Next, the light environment control mode according to the embodiment of the present invention will be described.

  The light environment control mode is a mode in which light adjustment and color adjustment are automatically executed so as to provide a comfortable light environment in accordance with a person's life rhythm.

  FIG. 11 is a diagram illustrating the dimming rate in the light environment control mode according to the embodiment of the present invention.

  Referring to FIG. 11, here, a case where the dimming rate between the daylight color and the light bulb color is adjusted based on the correlation with the human biological rhythm for 24 hours is shown.

  Specifically, 24 hours are divided into six periods of periods tA to tf, and the dimming ratio between the daylight color and the light bulb color in each period is set.

  Specifically, the period tA is set from 5:30 to 6:30. The period tB is set from 6:30 to 18:00. The period tC is set from 18:00 to 19:00. The period tD is set from 19:00 to 21:00. The period tE is set to 21:00 to 22:00. The period tF is set from 23:00 to 5:30. Here, it is assumed that wake-up time 6:30, dinner time 19:00, and bedtime 23:00 are preset as defaults. As will be described later, it is also possible to change the wake-up time 6:30, dinner time 19:00, and bedtime 23:00 in the setting of my home flow. This point will be described later.

  FIG. 12 is an operation table for explaining the operation of the illumination unit 30 in each period of the light environment control mode.

  Referring to FIG. 12, an early morning operation is executed in one hour from one hour before the wake-up time, which is period tA (time 5:30 to 6:30). Specifically, the brightness is changed from a night light control rate of 30% to a light control rate of 100%. Further, the color tone is changed from a light bulb color to a daylight color. As will be described later, the nighttime dimming rate can be changed.

  During the period tB (6:30 to 18:00) from the wake-up time to one hour before dinner time, the daytime operation is executed. Specifically, the dimming rate of 100% is maintained as the brightness. The daylight color is maintained as the color tone.

  The sunset operation is executed in one hour from one hour before the dinner time, which is the period tC (18:00 to 19:00). Specifically, the dimming rate of 100% is maintained as the brightness. Also, the color tone is changed from daylight color to light bulb color.

  In the period tD (19:00 to 21:00), the dinner operation is executed from the dinner time to 2 hours before the bedtime. Specifically, the dimming rate of 100% is maintained as the brightness. In addition, the color of the bulb is maintained as the color tone.

  The bedtime operation is executed for 2 hours from 2 hours before the bedtime, which is the period tE (21:00 to 22:00). Specifically, the brightness is changed from 100% dimming rate to 30% nighttime dimming rate. In addition, the color of the bulb is maintained as the color tone.

  During the period tF (23:00 to 5:30) from the bedtime to 1 hour before the wake-up time, the nighttime operation is executed. Specifically, the nighttime dimming rate of 30% is maintained as the brightness. In addition, the color of the bulb is maintained as the color tone.

  The above-described operation table is an example, and the time and period set in the operation table can be set to different times and periods, respectively, and further, another operation is provided. It is also possible. For example, the operation table may be changed according to the season.

  Referring to FIG. 11 again, before waking up during period tA, the dimming rate is gradually adjusted to brighten to suppress melatonin secretion, and the color tone is changed from the light bulb color to the daylight color, so that At the same time, the sleep is gradually shallowed and the dimming rate is set to 100% at the time of waking up, so that it is possible to promote a refreshing awakening with a daylight color close to natural light in the daytime.

  And, during the day of the period tB, it is possible to promote comfortable work during the human activity period by setting the daylight color close to the color of natural light.

  And before dinner at period tC, it is possible to create a relaxing effect by gradually changing the color tone from daylight color to light bulb color close to that of natural light in the evening, and it is possible to change the environment naturally to a calm and warm atmosphere. is there.

  And after the dinner of the period tD, it is possible to obtain a feeling of comfort in the calm atmosphere of the human calm period by maintaining the color of the light bulb.

  And before going to bed during the period tE, the dimming rate is gradually adjusted to darken, thereby lowering the level of human arousal and promoting the increase in melatonin secretion related to the human biological rhythm. It is possible to promote.

  And while sleeping during the period tF, while keeping the dimming rate low, deep sleep is promoted, and the dimming rate is such that the user can recognize an object, and operation at night is also possible.

  Therefore, it is possible to realize an optical environment that automatically adjusts the brightness and color tone according to the human biological rhythm by the optical environment control mode of the lighting device 1 described above. In particular, in the light environment control mode according to the present embodiment, it is naturally changed so as not to cause an uncomfortable feeling or an unpleasant feeling to the human in each period in which the light control rate and the color tone are changed.

  For example, in the period tA, the light bulb color with the light control rate of 30% is gradually adjusted to the daylight color with the light control rate of 100%.

  FIG. 13 is a diagram for explaining a graph of dimming rates of daylight color and light bulb color according to the embodiment of the present invention in the period tA.

  Referring to FIG. 13, here, changes in daylight color control rate, light bulb color control rate, and overall light control rate are shown.

  In the period tA, in the initial state, the dimming rate of the light bulb color is 30%, and the dimming rate of the daylight color is 0%. Therefore, the case where the whole light control rate is set to 30% is shown.

  An expression for calculating the light control rate in the graph will be described.

  The case where the overall dimming rate R is linearly changed from the dimming rate A in the initial state to the dimming rate B during the period T is expressed by the following equation (1). Note that the variable t is time.

Next, general formulas for the dimming ratios P and Q of daylight color and light bulb color are represented by the following formulas (2) and (3).

Thus, when the formula (1) is substituted into the formulas (2) and (3), the dimming rates P and Q of the daylight color and the light bulb color are expressed by the following formulas (4) and (5).

Then, the dimming ratios P and Q of the daylight color and the light bulb color when substituting the period T = 60, the dimming rate A = 30, and the dimming rate B = 100 into the formulas (4) and (5) are as follows: ), (7).

Based on the formulas (6) and (7), it is possible to set the dimming rates P and Q of the daylight color and the light bulb color.

  For example, the daylight color P and the light bulb color R after 12 minutes from the initial state, that is, when t = 12, are calculated as follows.

Based on this formula, it is possible to change the overall dimming rate linearly and to naturally change from a light bulb color to a daylight color. In other words, when changing from light bulb color to daylight color, it changes to an intermediate color that mixes the light bulb color and daylight color, and finally changes to daylight color, so the dimming rate can be changed without causing discomfort or discomfort to humans. It becomes possible, and it becomes possible to realize a comfortable and natural light environment.

  Further, in the light environment control mode according to the present embodiment, in the period tC, the daylight color with the light control rate of 100% is gradually adjusted to the light bulb color with the light control rate of 100%.

  FIG. 14 is a diagram illustrating a daylight color and light bulb color dimming rate graph according to the embodiment of the present invention in the period tC.

  Referring to FIG. 14, here, changes in daylight color adjustment rate, light bulb color adjustment rate, and overall dimming rate are shown.

  In the period tC, in the initial state, the dimming rate of the light bulb color is 100% and the dimming rate of the daylight color is 0%. Therefore, the case where the whole light control rate is set to 100% is shown.

  When the formulas for the dimming ratios of daylight color and light bulb color are calculated in the same manner as described above, the following formulas (8) and (9) are obtained.

Based on the formulas (8) and (9), the dimming ratios P and Q of the daylight color and the light bulb color can be set.

  Based on this formula, it is possible to naturally change from a light bulb color to a daylight color while maintaining the overall dimming rate. In other words, when changing from daylight color to light bulb color, the color tone is changed without causing any sense of incongruity or discomfort to humans because it continuously changes to an intermediate color in which daylight color and light bulb color are mixed, and finally changes to light bulb color. And a comfortable and natural light environment can be realized.

  In this example, an example is described in which the color temperature is controlled to change at a constant change rate with the passage of time when changing from daylight color to light bulb color in the period tC. However, the present invention is not limited to this, and the color temperature is high. By changing the color tone continuously so that the color temperature changes faster as the daylight color is closer, and the color temperature changes more slowly as it approaches the light bulb color with a lower color temperature, the color tone is equally spaced over time. Can make the user feel as if the changes. For example, in the case of changing from daylight color to light bulb color, the rate of change in color temperature may be reduced at equal intervals over time in order to reduce the rate of change in color temperature per hour.

  In the light environment control mode according to the present embodiment, the light bulb color with a light control rate of 100% is gradually adjusted to the light bulb color with a light control rate of 30% in the period tE.

  FIG. 15 is a diagram illustrating a graph of the dimming rate of the light bulb color according to the embodiment of the present invention in the period tE.

  Referring to FIG. 15, in the period tE, in the initial state, the dimming rate of the light bulb color is 100%, and the overall dimming rate is set to 100%.

  When the formula of the light bulb color dimming rate is calculated in the same manner as described above, it is expressed by the following formula (10).

Based on the formula (10), it is possible to set the dimming rate Q of the light bulb color.

  Based on this formula, it is possible to realize a comfortable light environment without causing the person to feel uncomfortable or uncomfortable by gradually changing the dimming rate Q of the light bulb color.

  Note that the method of setting the dimming rate of the light bulb color is an example, and for example, it is possible to adjust at the following rate of change.

  FIG. 16 is a diagram illustrating another graph of the dimming rate of the light bulb color according to the embodiment of the present invention in period tE.

  Referring to FIG. 16A, in this example, a log-log graph in which the vertical axis and the horizontal axis are logarithms is shown. The unit of the vertical axis is 0.1%. The unit of the horizontal axis is minutes.

  In the log-log graph, the case where the relationship between the light control rate and time is set to be linear is shown. Specifically, the case where the dimming rate of 100% is adjusted to the dimming rate of 30% during the period of 60 minutes in the log-log graph is shown.

  Referring to FIG. 16B, there is shown a case where the log-log graph of FIG. 16A is a normal graph.

  By adjusting the dimming rate Q of the light bulb color by this method, it becomes possible to change the dimming rate without further causing discomfort or discomfort to humans, and to realize a comfortable and natural light environment. It becomes possible.

  FIG. 17 is a diagram illustrating a flow of the light environment control mode according to the embodiment of the present invention.

  This flow is executed when the CPU 22 reads a program stored in the memory 29.

  Referring to FIG. 17, CPU 22 determines whether there is my home setting (step S30).

  In step S30, if the CPU 22 determines that there is my home setting, it acquires my home information (step S32). In addition, my home flow information will be described later.

  In step S30, if the CPU 22 determines that there is no home flow setting, the CPU 22 acquires a default value (step S34).

  Then, the CPU 22 sets a light environment control operation period based on my home flow information or default value (step S36). Specifically, the periods tA to tF are set according to the above-described wake-up time, dinner time, and bedtime.

  Then, the CPU 22 confirms the current time (step S38).

  Next, the CPU 22 determines whether the current time is within any of the periods tA to tF according to the current time (step S40).

  In step S40, the CPU 22 determines which of the periods tA to tF, and if it is within the periods tB, tD, and tF, the process proceeds to step S42.

  On the other hand, in step S40, the CPU 22 determines which of the periods tA to tF is within the period tA, tC, tE, and proceeds to step S52.

  First, when the CPU 22 determines that the current time is within the periods tB, tD, and tF, the CPU 22 sets the dimming rate according to the operation of the corresponding period (step S42).

  Next, the CPU 22 determines whether or not the remaining time of the corresponding period is less than 10 minutes (step S44).

  If it is determined in step S44 that it is less than 10 minutes, the dimming rate according to the operation of the corresponding period is set for 10 minutes (step S48).

  And it is judged whether 10 minutes passed (step S50). If 10 minutes have passed, proceed to the next step.

  That is, when the current time when the light environment control mode starts is just before the operation of the corresponding period of the light environment control operation period ends, in this example, when it is less than 10 minutes, For 10 minutes, the operation of the period corresponding to the light environment control operation period is continued. By this method, it is possible to prevent the user from feeling uncomfortable or uncomfortable by immediately executing the operation in the period following the corresponding period of the light environment control operation period. In this example, 10 minutes is set as a reference as an example. However, the present invention is not limited to this, and may be adjusted according to the user's preference.

  When determining in step S44 that the remaining time of the corresponding period is not less than 10 minutes (NO in step S44), the CPU 22 determines whether or not the period has ended (step S46).

  If the period ends in step S46, the process proceeds to the next step.

  Again, in step S40, if the CPU 22 determines that the current time is within the periods tA, tC, and tF, the CPU 22 determines whether it is less than 10 minutes from the disclosure time of the periods tA, tC, and tF. (Step S52).

  If it is determined in step S52 that it is less than 10 minutes (YES in step S52), the dimming rate according to the operation in the previous period is set for 10 minutes (step S54).

  Then, it is determined whether or not 10 minutes have passed (step S56).

  If it is determined in step S56 that 10 minutes have elapsed, the dimming rate is set according to the operation during the corresponding period (step S58).

  Then, it is determined whether or not the period has expired (step S60). If the period has expired, the process proceeds to the next step S52.

  That is, when the current time when the light environment control mode is started is a period corresponding to a period during which the light control rate and / or color tone is changed in the light environment control operation period (period tA, tC, tE) If it is less than 10 minutes from the start time of the period, the operation is executed without causing the user to feel uncomfortable or uncomfortable.

  Specifically, first, the dimming rate according to the operation of the previous period is set for 10 minutes, and after 10 minutes, the operation of the corresponding period for changing the dimming rate and / or the color tone is started. With this method, it is possible to prevent the user from feeling uncomfortable or uncomfortable during the light environment control operation period by immediately executing the operation of the corresponding period for changing the dimming rate and / or the color tone. In this example, 10 minutes is set as a reference as an example. However, the present invention is not limited to this, and may be adjusted according to the user's preference.

  On the other hand, if the CPU 22 determines in step S52 that it is not less than 10 minutes, it proceeds to the next step.

  That is, when the current time when the light environment control mode is started is a period corresponding to a period during which the light control rate and / or color tone is changed in the light environment control operation period (period tA, tC, tE) If it is 10 minutes or more from the start time of the period, the dimming rate is set according to the operation of the next period. By this operation, it is possible to avoid that the operation of the corresponding period for changing the light control rate and / or the color tone is immediately executed and the user feels uncomfortable or uncomfortable.

  In step S62, the dimming rate is set according to the operation in the next period (step S62).

  Then, it is determined whether or not the period has ended (step S64). If it is determined that the period has expired (YES in step S62), the process returns to step S62, and the dimming rate is set according to the operation in the next period.

  As an example by repeating the process, for example, the operation of the period tA → tB → tC → tD → tE → tF → tA is repeated, and the dimming according to the human life rhythm of 24 hours is executed. It becomes possible.

  When the light environment control mode is ended, the user presses the “light environment control” button 58 of the remote controller 50 again to stop the light environment control mode by interrupt processing, and the process returns to step S1 in FIG. Assume that normal lighting is performed.

  Further, when the user operates the power switch to turn off the power switch, the light environment control mode is ended because the supply of power is stopped. When the user turns on the power switch again, the process returns to step S1 in FIG. 7 and normal lighting is executed.

<My home style setting>
Next, my home setting will be described.

  My home setting is a mode in which the wake-up time, dinner time, and bedtime in the light environment control mode described above are set to a time that matches the individual life rhythm of the user.

  When the user presses the “My Home Flow” setting button 62 of the remote controller 50, the mode shifts to my home flow setting mode.

  FIG. 18 is a diagram illustrating set times for the wake-up time, dinner time, and bedtime in my home setting according to the embodiment of the present invention.

  Referring to FIG. 18, here, a case is shown in which wake-up time, dinner time, and bedtime can be freely set between 0:00 and 23:59, respectively.

  The wake-up time is set so as not to accept a time setting within 1 hour 59 minutes from the bedtime.

The dinner time is set not to accept a time setting within 59 minutes after the wake-up time. If not accepted, the initial preset time is set.

  Hereinafter, the flow of setting my home flow will be described in detail.

  When the user presses the “My Home” setting button 62 on the remote controller 50, a setting screen is displayed on the remote controller 50 side. Specifically, when the CPU 86 reads out the program stored in the memory 80, a setting screen according to the following is displayed on the liquid crystal panel 52.

  FIG. 19 is a diagram illustrating a home setting screen on liquid crystal panel 52 of remote controller 50 according to the embodiment of the present invention.

  Referring to FIG. 19A, when “My Family Style” setting button 62 is pressed, a screen on which the wake-up time can be set is first displayed on liquid crystal panel 52. The user can set the wake-up time to an arbitrary value by operating the “UP” button 57A and / or the “DOWN” button 57B. In this example, as an example, the default of the wake-up time is displayed by operating the “UP” button 57A and / or the “DOWN” button 57B together with the message “Please set the wake-up time” on the liquid crystal panel 52. A case where the value is changed from “6:30” set as the value to “7:00” is shown. Then, in the case of “OK”, please press the “My Home Style” setting button. ”Is shown. The remote controller 50 outputs the wake-up time information (here, 7:00) displayed on the liquid crystal panel 52 to the lighting device 1 when the user presses the “My Home” setting button. Then, the process proceeds to setting dinner time.

  Referring to FIG. 19B, a screen on which dinner time can be set is displayed on liquid crystal panel 52. The user can set the dinner time to an arbitrary value by operating the “UP” button 57A and / or the “DOWN” button 57B. In this example, as an example, the default of dinner time is displayed by operating the “UP” button 57A and / or the “DOWN” button 57B together with the message “Please set dinner time” on the liquid crystal panel 52. A case where the value is changed from “19:00” set as a value to “19:30” is shown. Then, in the case of “OK”, please press the “My Home Style” setting button. ”Is shown. The remote controller 50 outputs the dinner time information (here, 19:30) displayed on the liquid crystal panel 52 to the lighting device 1 when the user presses the “My Home” setting button. Then, the process shifts to setting the bedtime.

  Referring to FIG. 19C, a screen on which the bedtime can be set is displayed on liquid crystal panel 52. The user can set the bedtime to an arbitrary value by operating the “UP” button 57A and / or the “DOWN” button 57B. In this example, as an example, the default of the bedtime is displayed by operating the “UP” button 57A and / or the “DOWN” button 57B together with the message “Please set the bedtime” on the liquid crystal panel 52. A case where the value is changed from “23:00” set as the value to “23:30” is shown. Then, in the case of “OK”, please press the “My Home Style” setting button. ”Is shown. The remote controller 50 outputs the bedtime information (here, 23:30) displayed on the liquid crystal panel 52 to the lighting device 1 when the user presses the “My Home” setting button. Then, the process proceeds to the setting of the night light control rate. In this example, in my home setting, it is possible to set the night dimming rate in the night operation together with the wake-up time, dinner time, and bedtime.

  Referring to FIG. 19D, a screen on which the nighttime dimming rate can be set is displayed on liquid crystal panel 52. The user can set the numerical value of the nighttime dimming rate to an arbitrary value by operating the “UP” button 57A and / or the “DOWN” button 57B. In the setting, the CPU 22 of the lighting device 1 controls the PWM control circuit 23 so that the dimming rate emitted from the lighting unit 30 becomes the dimming rate displayed on the liquid crystal panel 52. Specifically, first, the dimming rate of the lighting device 1 is set to 30%. Then, an instruction to increase / decrease the dimming rate is output to the lighting device 1 in accordance with the input of the “UP” button 57A and / or the “DOWN” button 57B from the remote controller 50. The CPU 22 of the lighting device 1 adjusts the dimming rate emitted from the lighting unit 30 to the PWM control circuit 23 in accordance with an instruction to increase / decrease the dimming rate.

  In this example, as an example, the “UP” button 57A and / or the “DOWN” button 57B are operated together with the message “Please set the dimming rate at night” on the liquid crystal panel 52. “30%” set as the default value of the light rate is shown. Then, in the case of “OK”, please press the “My Home Style” setting button. ”Is shown. The remote controller 50 outputs the nighttime dimming rate information (30% in this case) finally displayed on the liquid crystal panel 52 to the lighting device 1 when the user presses the “My Home” setting button 62.

  FIG. 20 is a diagram illustrating a flow of setting my home flow according to the embodiment of the present invention.

  This flow is executed when the CPU 22 reads a program stored in the memory 29.

  With reference to FIG. 20, when it transfers to my home flow setting mode, CPU22 judges whether there exists any input of wake-up time information (step S120). Specifically, the determination is made based on whether or not the wake-up time information from the remote controller 50 described in FIG. 19 has been received.

  In step S120, when CPU 22 determines that there is an input of wake-up time information (YES in step S120), CPU 22 sets the wake-up time according to the input content (step S122). And it returns to step S120 again.

  Next, when it is determined in step S120 that the wake-up time information has not been input (NO in step S120), the CPU 22 determines whether or not supper time information has been input (step S124). Specifically, the determination is based on whether or not the dinner time information from the remote controller 50 described in FIG. 19 has been received.

  If CPU 22 determines in step S124 that dinner time information has been input (YES in step S124), CPU 22 sets the dinner time according to the input content (step S126). And it returns to step S120 again.

  Next, when it is determined in step S124 that the time information has not been input (NO in step S124), the CPU 22 determines whether or not the bedtime information has been input next (step S128). Specifically, the determination is made based on whether the bedtime information from the remote controller 50 described in FIG. 19 has been received.

  In step S128, when CPU 22 determines that there is an input of bedtime information (YES in step S128), CPU 22 sets the bedtime according to the input content (step S130).

  Then, the CPU 22 sets the dimming rate to 30% (step S172). Specifically, the CPU 22 controls the PWM control circuit 23 so that the dimming rate according to the light emission of the LED module 32 is 30%. By this operation, the user can recognize the brightness of the night light control rate with the light control rate of 30%.

  Then, the process returns to step S120.

  Next, in step S128, when CPU 22 determines that there is no input of bedtime information (NO in step S128), CPU 22 determines whether there is an input instruction for “UP” button 57A or “DOWN” button 57B. (Step S134).

  If it is determined in step S134 that there is an input instruction for “UP” button 57A or “DOWN” button 57B (YES in step S134), dimming is performed according to the input instruction for “UP” button 57A or “DOWN” button 57B. The rate is adjusted (step S136).

  And it returns to step S120 again. With this operation, the user can recognize the brightness of the nighttime dimming rate according to the adjustment of the dimming rate according to the input instruction of the “UP” button 57A or the “DOWN” button 57B.

  The user can arbitrarily set the night dimming rate according to the desired brightness by operating the “UP” button 57A and / or the “DOWN” button 57B.

  If it is determined in step S134 that there is no instruction to input the “UP” button 57A or the “DOWN” button 57B (NO in step S134), it is determined whether there is an input of night light control rate information (step S138). ). Specifically, the determination is made based on whether or not the nighttime dimming rate information from the remote controller 50 described in FIG. 19 is received.

  If it is determined in step S138 that night dimming rate information has been input (YES in step S138), the night dimming rate is set according to the input content (step S140). Then, the process ends (return). That is, the process returns to step S1 in FIG.

  On the other hand, if it is determined in step S138 that there is no input of nighttime dimming rate information (NO in step S138), the process returns to step S120.

  By this operation, it is possible to set the wake-up time information, the dinner time information, the bedtime information, and the nighttime dimming rate information, which are my home flow information in the light environment control mode. The home flow information is stored in the memory 29. Then, by storing my home flow information in the memory 29, it is determined that there is my home flow setting in step S30 of FIG.

  In the light environment control mode, the light environment control operation period is set based on the wake-up time, dinner time, and bedtime, which are my home flow information stored in the memory 29 in step S36 described in FIG. Once set, it is possible to execute the lighting environment control mode according to the home setting. Moreover, it becomes possible to set to the night light control rate according to the night light control rate information.

  Therefore, it is possible to realize a comfortable light environment by executing dimming and toning according to the individual life rhythm of each person.

  Even when the above-described light environment control mode is executed, when the user presses the “my home style” setting button 62 of the remote controller 50, the process shifts to my home style setting mode by interrupt processing. And when my home setting mode is completed, the process of the light environment control mode in FIG. 17 is executed again. With this process, the light environment control mode is executed based on the newly set home flow information, and a comfortable light environment can be realized.

  In this example, the case of setting three times and the nighttime dimming rate in my home setting mode has been described. However, the present invention is not limited to this, and the period and operation shown in FIG. It may be possible to set it in accordance with. In that case, for example, in each period shown in FIG. 12, it may be possible to set to turn on using a lighting state registered in favorite registration described later.

<Eco lighting mode>
Next, the eco lighting mode will be described.

  In the eco lighting mode, the light is dimmed at a constant rate with respect to the luminance at the start of lighting (light emission output from the illumination unit 30) in a certain time from the start of lighting. That is, at the start of lighting, the light is lit with the set brightness. Note that “when lighting starts” includes a case where the brightness is changed by a user operation.

  For example, 10 minutes is set as a certain time from the start of lighting or the change of the dimming rate or the color tone, and 20% of the initial dimming value X which is the luminance at that time is set as a certain ratio. In 10 minutes from the start of lighting, the dimming value is dimmed until it reaches 80% of the initial dimming value X.

  FIG. 21 is a diagram illustrating a graph of the dimming rate in the eco lighting mode according to the embodiment of the present invention.

  Referring to FIG. 21A, in this example, a log-log graph in which the vertical axis and the horizontal axis are logarithms is shown. The unit of the vertical axis is 0.1%. The unit of the horizontal axis is seconds.

  The logarithmic graph shows a case where light is dimmed so that the relationship between the light control rate and time is linear. Specifically, a case where the dimming rate of 100% is adjusted to the dimming rate of 80% during the period of 10 minutes (600 seconds) in the log-log graph is shown.

  Referring to FIG. 21 (B), a case where the log-log graph of FIG. 21 (A) is a normal graph is shown.

  By dimming by this method, it is possible to diminish without causing further discomfort or discomfort to humans, and it is possible to save energy while realizing a comfortable and natural light environment.

  FIG. 22 is a flowchart illustrating processing in the eco lighting mode according to the embodiment of the present invention.

  This flow is executed when the CPU 22 reads a program stored in the memory 29.

  The CPU 22 executes the process shown in FIG. 21 by an interrupt process at a predetermined interval (for example, every 1 second).

  With reference to FIG. 22, first, the CPU 22 determines whether or not to start lighting (step S160). If it is determined that the lighting has not started (NO in step S160), the process proceeds to step S166.

  On the other hand, if the CPU 22 determines that the lighting has started (YES in step S160), it sets the dimming rate to 100% (step S162). Specifically, the CPU 22 controls the PWM control circuit 23 so that the dimming rate according to the light emission of the LED module 31 and / or the LED module 32 is 100%. By this control, the user can recognize the brightness with a light control rate of 100% at the start of lighting.

  Next, the CPU 22 sets a dimming timer for measuring the dimming time to a predetermined time (600 seconds in this example), and determines a dimming rate (80% in this example) as a dimming target. End processing (return). That is, the process returns to step S1 in FIG.

  On the other hand, when it is determined in step S160 that the lighting has not started (NO in step S160), the CPU 22 determines whether or not the dimming timer is 0 (step S166). If it is determined that the dimming timer is 0 (NO in step S166), the process ends (return).

  If it is determined in step S166 that the dimming timer is not 0 (YES in step S166), the CPU 22 executes a dimming process (step S168).

  FIG. 23 is a diagram for explaining the subroutine of the dimming process in step S168.

  Referring to FIG. 23, when the dimming process starts, CPU 22 assigns the dimming timer at that time as a variable to the relational expression showing the relationship between the dimming rate and time shown in FIG. Thus, the value (dimming rate) that is dimmed at that time is calculated as the DOWN value (step S180).

  Then, the CPU 22 sets a value obtained by subtracting the calculated DOWN value from the current output value (dimming rate) as the dimming rate (step S182). Specifically, the CPU 22 controls the PWM control circuit 23 so that the dimming rate according to the light emission of the LED module 31 and / or the LED module 32 becomes the calculated value.

  Thereafter, the CPU 22 decrements the dimming timer by 1 (step S184) and ends the dimming process (return).

  The above example represents the operation from the start of lighting, but the same operation is performed even when the dimming rate or color tone is changed.

  With this operation, in the eco lighting mode, the luminance gradually decreases as shown in FIG. 21 until a predetermined ratio of luminance with respect to the luminance at the start of lighting or at the time of changing the dimming rate or color tone in a certain time from the start of lighting. Lighted. In this example, as shown in FIG. 21, the dimming rate is linearly changed with time in the logarithmic graph in which the vertical axis and the horizontal axis are logarithmic. May be linearly changed. As a result, the dimming rate can be changed without causing a human to feel uncomfortable or uncomfortable, and energy can be saved while realizing a comfortable and natural light environment.

  In the eco lighting mode, a lighting control instruction is output from the remote controller 50 when the user presses the “eco lighting” button 60. In response to the input of the lighting control instruction from the remote controller 50, the CPU 22 of the lighting device 1 instructs the PWM control circuit 23 to start lighting control on the lighting unit 30. Here, it is assumed that “eco-lighting mode” → “normal mode” → “eco-lighting mode” →... Is repeated in accordance with pressing of the “eco-lighting” button 60, that is, input of a lighting control instruction from the remote controller 50. That is, when a lighting control instruction is input from the remote controller 50 during the eco lighting mode, the CPU 22 of the lighting device 1 cancels the eco lighting mode. At this time, the CPU 22 controls the PWM control circuit 23 so as to obtain the luminance at the start of lighting.

  The eco lighting mode can be combined with the light environment control mode. In this case, in each lighting control in the six periods tA to tf of the light environment control mode, the CPU 22 gradually dims to a predetermined ratio of luminance with respect to the luminance at the start in a certain time from the start of the period. To do. Moreover, the light source concerning this invention is not limited to LED, Light sources, such as a fluorescent lamp and EL (Electro-Luminescence), may be sufficient.

<Illuminance sensor mode>
Next, the illuminance sensor mode will be described.

  The illuminance sensor mode is a mode for controlling the dimming rate based on the acquisition result of the illuminance sensor 28 so that the illuminance is set in advance.

  When the user presses the “illuminance sensor” button 70 of the remote controller 50, the illuminance sensor mode is entered.

  In the illuminance sensor mode, the CPU 22 acquires the measurement result of the illuminance sensor 28 at a predetermined number of times (for example, 8 times every 0.5 milliseconds). Then, this average value is calculated. This average value is defined as a measured value M1. The CPU 22 repeats the calculation of the measurement value M1 for a predetermined period to make a predetermined area of the memory 29. Then, the trim average of the measurement value M1 for a predetermined number of times (for example, 10 times) is calculated. This average value is defined as a measured value M2. The average value is obtained every 4 milliseconds by acquiring the measurement result of the illuminance sensor 28 8 times every 0.5 milliseconds and calculating the measurement value M1, and the measurement value M2 is obtained for 10 times of the measurement value M1. By calculating, an average value of 2 seconds is obtained.

  Prior to the illuminance sensor mode, a target illuminance is set. Setting of the target illuminance is performed when the user presses the “environment registration” button 69 of the remote controller 50. That is, when receiving a signal indicating that the “Environment Registration” button 69 has been pressed, the CPU 22 calculates the measured value M2 described above, and acquires the calculated measured value M2 as a value representing the illuminance at that time. Then, the acquired value is written in the predetermined area of the memory 29 as “target illuminance”.

  The target illuminance is set by setting the “environment registration” button 69 after the user adjusts the dimming rate so as to obtain a desired brightness with the remote controller 50 after the outside light does not enter the room where the lighting device 1 is installed. The desired illuminance can be accurately set as the “target illuminance” by pressing.

  In this example, the “target illuminance” is set by adjusting the dimming rate so that the user himself / herself has a desired brightness with the remote controller 50. However, the default value is set in the memory 29 in advance. A plurality of “target illuminance” values may be registered so that the user can select from the plurality of “target illuminance” and set “target illuminance”.

  Further, the CPU 22 sets a multi-level illuminance level based on the target illuminance so that the user can change the target illuminance. For each illuminance level, a high level and a low level that define a target illuminance range are set in order to prevent hunting. Here, the target illuminance is set to a high level of illuminance level 1, and the low level of illuminance level 1 having a lower illuminance level and the high level and low level of illuminance levels 2 and 3 having higher illuminance levels than illuminance level 1 are set. .

  FIG. 24 is a diagram for explaining setting of the illuminance level.

  Referring to FIG. 24, as an example, CPU 22 sets target illuminance (A value in the figure) as “high level of illuminance level 1”, and high illuminance level 1 as “high level of illuminance level 2”. Set the illuminance 1.2 times the level (B value in the figure), and set the illuminance 1.2 times the high level of the illuminance level 2 (C value in the figure) as the “high level of illuminance level 3” To do. Furthermore, the illuminance 0.9 times the illuminance set as the high level is set as the low level of each illuminance level. In addition, an illuminance that is 0.5 times the target illuminance (A value in the figure) is set as a determination value used for “dark determination” for detecting a sudden darkening, which will be described later.

  The CPU 22 registers a “brightness level” in advance in the memory 29 for each brightness (illuminance) for control in the illuminance sensor mode. The unit of brightness is lux (lx).

  FIG. 25 is a diagram illustrating an example of the correspondence between the brightness level and the registered brightness.

  In the example of FIG. 25, the brightness level 28 represents all the lights, and the brightness level 1 represents the light. In accordance with the above correspondence, the CPU 22 performs dimming within the brightness level 28 (all lamps) to 1 (slight lamp) in the illuminance sensor mode.

  There are two types of control in the illuminance sensor mode: control at start time and normal control. When the illuminance sensor mode is started, the control at the start is performed, and then the normal control is performed according to the determination result.

  FIG. 26 is a diagram illustrating a flow of the illuminance sensor mode according to the embodiment of the present invention.

  This flow is executed when the CPU 22 reads a program stored in the memory 29.

  Referring to FIG. 26, when shifting to the illuminance sensor mode, CPU 22 performs illuminance measurement (step S220). The illuminance measurement here refers to processing for calculating the measurement value M2 from the measurement result from the illuminance sensor 28 as described above.

  When the measurement value M2 for one time is obtained, that is, in the above example, when the measurement value M2 that is the average value of the measurement results for 2 seconds is obtained (YES in step S222), the CPU 22 determines that the measurement value M2 is A determination operation for comparing with the set illuminance level 1 which is the target illuminance is performed.

  As a result of the determination operation, when the measured value M2 indicates an illuminance higher than the high level of the illuminance level 1 that is the target illuminance (YES in step S224), the CPU 22 decreases the current brightness level by one step. The dimming rate is changed (step S226).

  When the measured value M2 indicates an illuminance lower than the low level of the illuminance level 1, which is the target illuminance (NO in step S224 and YES in step S228), the CPU 22 increases the current brightness level by one level. The dimming rate is changed (step S230).

  When the dimming rate is changed in step S226 or step S230, the CPU 22 thereafter returns to the operation of step S220. Then, the above operation is repeated until it is determined that the measured value M2 indicates the illuminance between the low level and the high level of the illuminance level 1, which is the target illuminance.

  When the measured value M2 indicates the illuminance between the low level and the high level of the illuminance level 1 that is the target illuminance (NO in step S224 and NO in step S228), the current brightness level becomes the target illuminance. As a match, the CPU 22 does not change the brightness level. Then, the above-described control at the time of start is finished, and the normal control is started.

  When shifting to normal control, the CPU 22 performs illuminance measurement (step S232). The illuminance measurement here refers to processing for calculating the measurement value M2 from the measurement result from the illuminance sensor 28 as described above, as in step S220.

  In the normal control, the CPU 22 performs the determination operation for comparing the measured value M2 with the set illuminance level 1 that is the target illuminance, and changes the brightness level when the determination result is the same twice. To do. At this time, the measurement value M2 obtained by using the measurement result of the CPU 22 and the illuminance sensor 28 in the middle of changing the brightness level (YES in step S234) is not used for the determination operation.

  That is, when the measurement value M2 indicates an illuminance higher than the high illuminance level 1 that is the target illuminance in both determination results (YES in step S236), the CPU 22 determines the current brightness level. The dimming rate is changed so as to decrease by one step (step S238).

  When the measurement value M2 indicates an illuminance lower than the low level of the illuminance level 1, which is the target illuminance, as a result of the two determination operations (NO in step S236 and YES in step S240), the CPU 22 The dimming rate is changed so as to increase the brightness level by one level (step S242).

  When the results of the two determination operations are different, or when the measurement value M2 indicates the illuminance between the low level and the high level of the illuminance level 1 that is the target illuminance in both the results of the two determination operations ( If NO in step S236 and NO in step S240), CPU 22 does not change the brightness level.

  The CPU 22 repeats the above normal control during the illuminance sensor mode.

  FIGS. 27 and 28 are diagrams for explaining the control at the start time and the normal control, respectively.

  Assuming that the measured value M2 is calculated every 2 seconds as in the above example, referring to FIG. 27, in the control at the start, the CPU 22 has the measured illuminance at the target illuminance every 2 seconds. Compared with the illuminance level 1, the brightness level is changed so as to approach the illuminance level 1. In the example of FIG. 27, if it is determined in the determination operation that the measured value M2 is lower than the target illuminance, the CPU 22 increases the brightness level by one step so as to approach the illuminance level 1. Then, when the measured value M2 reaches within the target illuminance range, the control at the start is finished. In the control at the start, the measured value M2 obtained when the brightness level is changed is also used for the next determination operation.

  Referring to FIG. 28, in the normal control, the CPU 22 compares the measured value M2 with the illuminance level 1 that is the target illuminance every 2 seconds, but the illuminance Change the brightness level to approach level 1. In the example of FIG. 28, if it is determined that the measured value M2 is lower than the target illuminance twice in succession in the determination operation, the CPU 22 sets the brightness level so as to approach the illuminance level 1 at the second determination. Move up one step. Further, the measurement value M2 obtained when the brightness level is changed is not used for the determination operation. By performing the determination operation of the measurement value M2 for changing the brightness level at least twice, the time interval for changing the brightness level can be set as compared with the control at the start of changing the brightness level by one determination operation. Can be delayed. Further, by not using the measurement value M2 obtained when the brightness level is changed for the determination operation, the time interval for changing the brightness level can be further delayed.

  As shown in FIGS. 27 and 28, in the illuminance sensor mode, the brightness level is changed at an interval shorter than the normal control in the control at the start until the target illuminance is reached. That is, at the beginning of shifting to the illuminance sensor mode, the dimming rate is controlled until the target illuminance is rapidly reached.

  For example, in the case of the above-described example, the shortest time required to change 27 steps from full light to low light in the control at the start time is the determination time (2 seconds × 27 = 54 seconds) + the last dimming change time ( 200 milliseconds) = 54.2 seconds.

  With such control, for example, when the target illuminance is set low, the power consumption can be suppressed more than when the dimming rate is gradually changed to the illuminance.

  On the other hand, in the normal control that is the control after reaching the target illuminance, the brightness level is changed at a longer interval than the control at the start. That is, once the target illuminance is reached, the dimming rate is controlled at intervals longer than the control at the start, that is, gently, according to the change in illuminance.

  For example, in the case of the above-described example, the shortest time required to change 27 steps from all lamps to the low lamps in the normal control is the determination time and the dimming change time (determination time to skip) (6 seconds × 26 = 156 seconds) + last determination time (4 seconds) + last dimming change time (200 milliseconds) = 160.2 seconds.

  By such control, once the target illuminance is reached, flicker due to changes in the brightness level at fine intervals can be suppressed, and discomfort can be suppressed.

  In this example, it was obtained when the number of determination operations for changing the brightness level of normal control was increased compared to the control at the start, and when the brightness level was changed in normal control. The example of delaying the time interval for changing the brightness level of normal control compared to the control at the start by using a method that prevents the measured value from being used for the judgment operation has been explained, but only one of the methods can be used at the start Control may be performed so as to delay the time interval for changing the brightness level in the normal control rather than the control in the above.

  In the illuminance sensor mode, for example, the user can change the target illuminance by pressing the “illuminance sensor” button 70 of the remote controller 50. Specifically, when the CPU 22 accepts pressing of the “illuminance sensor” button 70 when the target illuminance is the illuminance level 1, the CPU 22 increases the illuminance level used for the determination operation from the current level to the illuminance level 2. Further, when the target illuminance is the illuminance level 2 and the depression of the “illuminance sensor” button 70 is accepted, the illuminance level 3 is increased by one step. If the depression of the “illuminance sensor” button 70 is accepted when the target illuminance is the illuminance level 3, the CPU 22 ends the illuminance sensor mode. In this example, the illuminance level is changed using the “illuminance sensor” button 70. However, the illuminance level may be changed using the “brighter” button 55 or the “darker” button 56. .

  As described above, when the target illuminance is set to the desired brightness level without external light entering the room, the light intensity is adjusted to the target illuminance set in the illuminance sensor mode after the external light enters. Even so, the user may feel that the illuminance in the room is insufficient due to the difference in illuminance inside and outside the room. Even in such a case, it is possible to increase the target illuminance from the initially set illuminance level 1 to the illuminance level 2 simply by pressing the “illuminance sensor” button 70 again. And can be dimmed. Therefore, it is not necessary to set the target illuminance again, so that convenience for the user is improved.

  At this time, it is preferable that the CPU 22 change the brightness level in the changed direction to such an extent that the human can recognize that the brightness has changed (for example, six levels), and then perform the above-described start control to control the light. Change the rate to the newly set target illuminance.

  Specifically, when the depression of the “illuminance sensor” button 70 is received in the illuminance sensor mode, the CPU 22 increases the illuminance level used for the determination operation by one step from the current level, and the dimming rate from the current brightness level. Change to 6 steps up. Thereafter, the CPU 22 performs control at the start, and rapidly changes the dimming rate so that the target illuminance range is obtained. When the illuminance level is raised, the brightness level is raised to the user by starting the control at the start after increasing the dimming rate from the current brightness level in multiple steps (6 steps in this example). Is more easily felt.

  Note that the CPU 22 preferably performs “dark determination” in the above-described normal control to determine whether ambient brightness has become extremely dark, such as a change in illuminance in the room when the curtain is closed, for example. Here, the determination value for “dark determination” described above is used.

  That is, when the measurement value M2 indicates an illuminance lower than the determination value for “dark determination” in the determination operation of the normal control, the CPU 22 determines that the ambient brightness has become extremely dark and immediately increases the brightness. The dimming rate is changed so that the level becomes the brightness level 28 corresponding to all the lights. Then, the control shifts to the start control.

  By performing such an operation, the target illuminance can be appropriately set even when the surrounding brightness becomes extremely dark, for example, when the curtain is closed.

  Such control can be combined with other control modes. For example, when applied to the light environment control mode in step S6 of FIG. 7, the illuminance sensor mode can be set for one hour before each set time. In this case, the color is only daylight, and the brightness level at the start of the illuminance sensor mode is the brightness level 28 corresponding to all the lights.

  Further, when the lighting mode is switched to the illuminance sensor mode when lighting is performed in the color tone registered in the favorite registration mode in step S18 of FIG. 7 described later, only the brightness is maintained while maintaining the color tone (color ratio) set in the favorite. Change in sensor mode. That is, the CPU 22 calculates the brightness level from the brightness registered as a favorite (the sum of the daylight color and the light bulb color), and sets the brightness level at the start of the illuminance sensor mode as the brightness level.

  Further, when the eco lighting mode and the illuminance sensor mode in step S10 of FIG. 7 are combined, the CPU 22 performs dimming within the brightness level range of 26 (80%) to 1 (slight). However, if the brightness level is 26 or more at the start of the illuminance sensor mode even in the eco lighting mode, the CPU 22 starts the illuminance sensor mode at that brightness level. Then, once the brightness level falls below 26, the dimming is performed so that the brightness level does not exceed 26 after that.

  The CPU 22 writes the brightness level at that time in a predetermined area of the memory 29 at the start of the illuminance sensor mode. When canceling the illuminance sensor mode, the CPU 22 returns to the brightness level at the start of the illuminance sensor mode.

<Timer mode>
Next, the timer mode will be described.

  The timer mode is a mode in which the lighting device 1 automatically turns on and off based on the time set by the user.

  In this example, the timer mode can be set to three timer modes in accordance with a user operation instruction. Specifically, the off timer mode, the on timer mode, and the absence timer mode will be described.

  FIG. 29 is a diagram illustrating a timer mode flow according to the embodiment of the present invention.

  Referring to FIG. 29, first, it is determined which timer mode has been instructed. Specifically, first, the CPU 22 determines whether or not there is an instruction to input the “answering timer” button 67 (step S20). In step S20, when CPU 22 determines that an answering timer control instruction output in accordance with pressing of “answering timer” button 67 provided on remote controller 50 is input (YES in step S20), it shifts to answering timer mode. (Step S21). Details of the absence timer mode will be described later.

  On the other hand, if the CPU 22 determines in step S20 that the input instruction of the “answering timer” button 67 has not been input (NO in step S20), then the CPU 22 has input timer setting information input. It is determined whether or not (step S22).

  FIG. 30 is a diagram illustrating an on timer setting screen and an off timer setting screen according to the embodiment of the present invention.

  When the user presses the “ON TIMER” button 75, the operation for setting the ON timer in the ON timer mode can be started. Specifically, by pressing the “on timer” button 75, an on timer setting screen (not shown) is displayed on the liquid crystal panel 52 as shown in FIG. In the on-timer setting screen, the user can set the lighting time using the “UP” button 57A and the “DOWN” button 57B. Then, by pressing the “on timer” button 75 again, on timer setting information is output from the remote controller 50. When the on timer setting information is output from the remote controller 50, for example, “on timer” is displayed on the liquid crystal panel 52. That is, information indicating that the on-timer mode has been started is stored in the memory 80 of the remote controller 50. For example, when “ON TIMER” button 75 of remote controller 50 is pressed again after “ON TIMER” is displayed on liquid crystal panel 52, an ON timer setting cancellation instruction is output from remote controller 50. The CPU 22 cancels the on-timer mode when there is an input of an on-timer setting cancellation instruction from the remote controller 50. When the on timer setting cancellation instruction is output from the remote controller 50, the “on timer” displayed on the liquid crystal panel 52 is not displayed. It is also possible to use in combination with other modes. Further, when lighting control in the on-timer mode is started once, control may be performed so that data is reset, or control is performed so that lighting control is repeatedly executed while data is held. May be.

  Similarly, when the user presses the “OFF TIMER” button 74, it is possible to start the operation for setting the OFF timer in the OFF timer mode. Specifically, when the “OFF TIMER” button 74 is pressed, the OFF timer setting screen is displayed on the liquid crystal panel 52 as shown in FIG. On the off timer setting screen, the user can set the turn-off time using the “UP” button 57A and the “DOWN” button 57B. Then, by pressing the “OFF timer” button 74 again, the OFF timer setting information is output from the remote controller 50. It should be noted that when the off timer setting information is output from the remote controller 50, for example, “off timer” is displayed on the liquid crystal panel 52. That is, the memory 80 of the remote controller 50 stores information indicating that the off timer mode has been started. For example, when the “OFF TIMER” button 74 of the remote controller 50 is pressed again after “OFF TIMER” is displayed on the liquid crystal panel 52, an instruction to cancel the OFF timer setting is output from the remote controller 50. The CPU 22 cancels the cutoff timer mode when there is an input of a cutoff timer setting cancellation instruction from the remote controller 50. It should be noted that when the disconnect timer setting cancellation instruction is output from the remote controller 50, the “OFF timer” displayed on the liquid crystal panel 52 is not displayed. It should be noted that it can be used in combination with other modes, for example, can be combined with the on-timer mode. Note that when the on timer mode and the off timer mode are combined, the set times can be prevented from overlapping, or can be set to the same time. When setting at the same time, either one of the modes may be prioritized, or processing according to both modes may be invalidated. Further, when the light-off control in the off timer mode is started once, the data may be controlled to be reset, or the data is held and the light-off control is repeatedly executed. May be.

  Referring to FIG. 29 again, in step S22, when CPU 22 determines that input timer setting information is input from remote controller 50 (YES in step S22), CPU 22 sets the lighting time in the on timer mode. With this processing, when the lighting time in the on-timer mode is set, the CPU 22 executes lighting control on the illumination unit 30 at the set time. For example, all the lights in daylight color (light control rate 100%) are set at the set time. Here, even when the lighting state is already set at the set time, it is possible to execute the lighting control in the on-timer mode.

  In this example, lighting control is executed with all lights in daylight color at the set time in the on-timer mode. However, the present invention is not limited to this, and the user can set the dimming rate and color tone in the on-timer mode. Also good. In that case, it may be set to light up in the lighting state with the light control rate and the color tone registered in the favorite registration mode described later.

  On the other hand, when it is determined in step S22 that no input timer setting information has been input from the remote controller 50, that is, when there has been input of the timer setting information from the remote controller (NO in step S22), the light is turned off in the timer OFF mode. Set the time. With this process, when the turn-off time in the off timer mode is set, the CPU 22 executes a turn-off control to the illumination unit 30 at the set time. Here, if the light is already off at the set time, no operation is performed.

  Next, an absence timer mode according to the embodiment of the present invention will be described.

  FIG. 31 is a diagram illustrating a flow in the absence timer mode according to the embodiment of the present invention.

  Referring to FIG. 31, first, CPU 22 sets an absence timer table that defines a lighting operation in the absence timer mode (step S90). Specifically, the CPU 22 refers to an absence timer table stored in advance in the memory 29 as an example.

  FIG. 32 is a diagram for explaining the absence timer table according to the embodiment of the present invention.

  Referring to FIG. 32, the absence timer table according to the embodiment of the present invention defines the operation of illumination unit 30 in the set time zone. Here, two patterns are shown, and a first day pattern and a second day pattern are provided.

  The pattern for the first day is set to brightness at time 18:30 as the absence timer control start time, dimming rate 50%, and daylight as the color tone. Note that the dimming rate of the light bulb color is set to 0%. Also, the brightness is set as the brightness at the time 21:00 as the switching time, the light control rate is set to 50%, and the light bulb color is set as the color tone. The daylight dimming rate is set to 0%. Further, the extinguishing state is set at 23:30 as the extinguishing time. Specifically, the dimming ratios of the daylight color and the light bulb color are both set to 0%.

  The pattern for the second day is set to brightness at time 18:00, a dimming rate of 50%, and a daylight color as the color tone. Note that the dimming rate of the light bulb color is set to 0%. At time 20:30, the brightness is set to 50%, and the color tone is set to the light bulb color. The daylight dimming rate is set to 0%. Further, the light is turned off at 23:00. Specifically, the dimming ratios of the daylight color and the light bulb color are both set to 0%.

  Here, only the pattern for two days is shown as an example, but another pattern (for example, the third day) may be provided. In this example, for example, in the case of the third day, the pattern of the first day is used again.

  The absence timer table is an example, and the set time can be set to another time, and the brightness and color tone can be set to different states. .

  For example, an answering timer setting screen such as the on-timer setting screen or the off-timer setting screen described above is displayed according to the input instruction of the “answering timer” button 67, and the answering timer control start time, switching time, turn-off time, adjustment time, etc. The light rate and the like may be settable. Alternatively, in this example, a case where the color tone is changed in the absence timer mode will be described, but only the dimming rate may be set to change over time. In this example, the case where the time is set using the “UP” button 57A and the “DOWN” button 57B will be described in this example. However, the present invention is not particularly limited to this method. For example, there is no such button. Alternatively, for example, the display time may be incremented according to the number of times the “answering timer” button 67 is pressed so that the time can be set. The same applies to other cases.

  In this example, as a pattern for the first day, the daylight color is not simply turned on and turned off, but is set to a light bulb color which is another color tone at a predetermined time thereafter. That is, the color tone is changed by adjusting the ratio of the dimming rate between the daylight color and the light bulb color that are the plurality of light emitting units. Therefore, by changing the color tone rather than simply turning on, it becomes easier to recognize the change in the illumination of the room even when viewed from the outside of the room. For example, even for criminals who repeat observations from outside the room where the lighting device 1 is installed with a time interval, the color of the light in the room has changed from daylight color to light bulb color without making the moment of color change visible. To be recognized. Thereby, it can be disguised as if the user is actually performing an operation to change the color tone of the lighting, and it is possible to further improve crime prevention by making it appear as if the user is at home.

  Further, as the absence timer table, it is possible to further improve the crime prevention property by using a pattern having different operations instead of using the same pattern continuously by providing a plurality of patterns.

  Also, at homes where pets are kept, even if the owner user is away, lighting control is performed according to the absence timer table, so there is no need to wait for the user to return in the dark, such as a pet It is also possible to reduce the stress given to the person.

  Also, since the absence timer mode can be set by pressing the “answer timer” button 67 provided on the remote controller 50 with one touch, a troublesome operation for setting the timer is unnecessary, and the usability is excellent.

  Referring again to FIG. 31, next, CPU 22 confirms the current time (step S91).

  Next, the CPU 22 determines whether or not the current time is the absence timer control start time (step S92). Specifically, for example, it is determined whether or not the current time is 18:30, which is the absence timer control start time of the pattern on the first day, for example.

  In step S92, when CPU 22 determines that the current time is the absence timer control start time (YES in step S92), it starts absence timer control (step S93). For example, based on the absence timer table of FIG. 31, first, the color tone is set to 50% as the daylight color, and the brightness is set to 50% as the brightness at time 21:00, and the light bulb color is set as the color tone. To do. Further, the light is turned off at time 23:30. For the second day, the absence timer control is executed using the pattern of the second day.

  Next, after starting the absence timer control in step S94, the CPU 22 determines whether there is an input instruction (step S94).

  If the CPU 22 determines in step S94 that there is an input instruction after the start of the absence timer control (YES in step S94), it cancels the setting of the absence timer mode (step S98). Then, the process ends (return).

  On the other hand, if it is determined in step S92 that the current time is not the absence timer control start time (YES in step S92), CPU 22 determines whether there is an input instruction (step S95).

  In step S95, when CPU 22 determines that there is an input instruction (YES in step S95), CPU 22 next determines whether there is an input instruction for the absence timer button (step S96).

  If CPU 22 determines in step S96 that the input instruction is an input instruction for the absence timer button (YES in step S96), it cancels the setting of the absence timer mode (step S98).

  On the other hand, when CPU 22 determines in step S96 that the input instruction is not an input instruction for the absence timer button (NO in step S96), that is, when it is determined that the input instruction is in accordance with other button operations. Performs normal processing according to other button operations (step S97). In the normal process, for example, when the “all lighting” button 54 of the remote controller 50 is pressed, the CPU 22 receives the input of the all lighting control instruction, and the entire lighting to the illumination unit 30 is performed with respect to the PWM control circuit 23. It is instructed to start control. The same applies to other button operations.

  And it returns to step S91 again. If it is determined in step S95 that there is no input instruction (NO in step S95), the process returns to step S91 and the same processing is repeated.

  That is, in the absence timer mode according to the embodiment of the present invention, when the current time is confirmed and the current time becomes the absence timer control start time, it is possible to start the absence timer control according to the absence timer table. Become.

  On the other hand, the CPU 22 cancels the setting of the absence timer mode when it is determined that there has been any input instruction since the absence timer control was started. For example, when the “all lighting” button 54 of the remote controller 50 is pressed after the absence timer control is started, the setting of the absence timer mode is cancelled. In this example, only the cancellation of the setting of the absence timer mode has been described, but the processing according to the button operation may be executed together. For example, the CPU 22 receives the input of the full lighting control instruction, cancels the setting of the absence timer mode, and instructs the PWM control circuit 23 to start the full lighting control to the illumination unit 30. Also good. The same applies to other button operations. Further, the present invention is not limited to the button operation of the remote controller 50, and can be similarly applied to the operation of the operation SW 42 of the lighting device 1.

  If there is an input instruction for the absence timer control button before the start time of the absence timer control, the setting of the absence timer mode is canceled, and if there is an input instruction according to other button operations, the absence timer Processing without giving priority to the button operation is executed without canceling the mode setting.

  For example, when the user returns home and operates the remote controller 50 after the absence timer control is started, the absence timer mode is terminated and normal processing is executed because it is known that the user has returned home. It is possible. At this time, for example, it is possible to cancel the setting of the absence timer mode by operating another button without pressing the “absence timer” button 67 again, which is a button for instructing the setting / releasing of the absence timer mode. For the convenience of the user. In other words, when the user returns home after the absence timer control is started, if the absence timer mode setting can be canceled only by pressing the “absence timer” button 67 again, the absence timer mode setting is canceled. (It is possible that the color tone may change unexpectedly due to forgetting to press the “Absence Timer” button 67 again) or that it may turn off unexpectedly. As described above, the user convenience is improved by loosening the release condition.

  On the other hand, if the release condition is relaxed so that the setting of the answering timer mode can be canceled by other button operations before the answering timer control is started, the answering timer mode may be canceled against the user's intention. And the convenience for the user decreases. Therefore, in the processing in the absence timer mode according to the embodiment of the present invention, even after the absence timer mode is set by pressing the “absence timer” button 67, before the absence timer control is started, The setting of the absence timer mode is not canceled by other button operations, and the user convenience is improved by giving priority to the processing according to the other button operations.

  In this example, the setting of the absence timer mode is canceled when the CPU 22 determines that there is some input instruction after the absence timer control is started. The absence timer mode may be canceled only when the above operation is input. Specifically, the absence timer may be canceled only when there is an input instruction to turn on the lighting device 1 such as “full lighting” or “favorite registration 1” after the absence timer control is started. That is, it is not necessary to cancel the absence timer mode by all input instructions other than the “answering timer” button 67, and there may be an input instruction that cannot cancel the absence timer mode.

  If the time when the absence timer mode is set is later than the absence timer control start time, for example, if the user presses the “answer timer” button 67 at 19:00, the next day The absence timer control may be started from the absence timer control start time, or the absence timer control may be executed immediately according to the absence timer table.

  In the above description, the case where the setting of the timer mode is canceled according to the instruction from the remote controller 50 has been described. However, for example, when the power switch included in the operation SW 42 of the lighting device 1 is turned off, the timer mode is set. The setting may be canceled. The absence timer mode may be combined with other modes, for example, the eco lighting mode.

  In this example, the case where the “answering timer” button 67 serves both as an input instruction for setting and canceling the answering timer mode has been described. However, input means for setting and releasing the answering timer mode (for example, buttons on the remote control) May be provided separately, and cancellation before the start of the absence timer control may be performed by an input means dedicated to cancellation of the absence timer mode.

  In this example, the case where the absence timer mode is executed using the absence timer table stored in advance in the memory 29 has been described. For example, the absence timer table is created by automatic learning. An absence timer table may be used. For example, the timing for turning on / off the lighting device 1 in one week (7 days) is stored, an average value is calculated, and the absence timer control start time, switching time, and turn-off time are automatically set. May be. Alternatively, the timing of turning on / off the lighting device 1 on weekdays and holidays in units of one week (7 days) is stored, the average value of each is calculated, the absence timer control start time on weekdays, the switching time, The turn-off time and holiday absence timer control start time, switching time, and turn-off time may be set automatically.

  In this example, the start time of the absence timer control is set based on the time measured by the CPU 22 according to the oscillation signal oscillated from the crystal oscillator 27. A configuration having a count timer that allows the user to set the time until the start of the absence timer control is not limited. Specifically, for example, the user sets and inputs so that the absence timer control is started after 3 hours, and the absence timer control is started after 3 hours from the user input, so that the start time of the absence timer control is set. It may be set.

<Brightness plus mode>
Next, the brightness plus mode will be described.

  The brightness plus mode is a mode in which the dimming rate is set to 100% or more. The lighting in the brightness plus mode is performed in the color tone at the time of shifting to the brightness plus mode. In other words, in this example, it is possible to light in the brightness plus mode in each of 10 color tones as an example between the “bulb color” having a low color temperature and the “daylight color” having a high color temperature.

  When the user presses the “brightness plus” button 64 of the remote controller 50, the mode shifts to the brightness plus mode.

  Specifically, when the lighting device 1 is lit in, for example, a daylight color tone, the CPU 22 receives a brightness plus button 64 when an instruction to input a “brightness plus” button 64 provided on the remote controller 50 is given. The mode is started, and the PWM control circuit 23 is instructed to adjust the PWM pulse S1 so that the dimming rate of the LED module 31 is 100% or more. As will be described later, when the dimming rate is set to 100%, the current supplied to the LED module 31 is provided with a certain margin so that light can be output with an illuminance higher than the rated illuminance of the LED module 31. The duty ratio is set at about 80%. Therefore, it is possible to set the dimming rate to 100% or more by eliminating the margin and supplying the current to the LED module 31 at a duty ratio of 100%. Here, it is assumed that the dimming rate can be set to 125%, for example.

  Note that the method of controlling the dimming rate of the LED module 31 in the brightness plus mode is not limited to the above, and a method of changing the LED drive current value may be used. Specifically, when the dimming rate is 100%, a margin is provided by setting the current value to about 80% or less of the rated current of the LED module 31, and is close to the rated current of the LED module 31 in the brightness plus mode. It may be controlled to light at a dimming rate of 100% or more by supplying a current of a value. Further, the dimming rate may be controlled by changing the number of LED modules to be lit. Specifically, when the dimming rate is 100%, a number of LEDs 31 corresponding to 80% of the plurality of LEDs 31 are lit at the rated current, and all LEDs 31 are lit at the rated current in the brightness plus mode. You may control to.

  On the other hand, the current close to the rated current is overloaded on the LED module 31. Therefore, the CPU 22 performs the following operation in the brightness plus mode.

  FIG. 33 is a diagram illustrating a flow in the brightness plus mode according to the embodiment of the present invention.

  This flow is executed when the CPU 22 reads a program stored in the memory 29.

  Referring to FIG. 33, when the mode is shifted to the brightness plus mode, CPU 22 determines whether or not the set time has elapsed with a timer according to the setting described later. As a result, when it is not timed, that is, after the set time has elapsed since the previous timer setting (YES in step S270), the CPU 22 sets a timer for measuring a predetermined time, and measures the time. Start (step S272). The predetermined time is a time for preventing the LED module 31 from being overloaded, and corresponds to, for example, 60 minutes. In this case, the CPU 22 sets the dimming rate to 125% and lights it for time T1 (for example, 5 minutes) (step S274).

  On the other hand, if it is timed, that is, if the set time (for example, 60 minutes) has not yet elapsed since the start of the previous brightness plus mode (NO in step S270), the CPU 22 sets the dimming rate to 125. %, And is lit for a time T2 (for example, 1 second) shorter than the time T1 (step S276).

  Thereafter, the CPU 22 dims until the dimming rate reaches 104% (step S278). The dimming here may be performed by changing the dimming rate shown in the graph of FIG. 15 or by changing the dimming rate shown in the graph of FIG. It may be.

  By performing such an operation, it is possible to realize a comfortable light environment by further improving the visibility according to the purpose by temporarily setting the daylight color dimming rate to 100% or more to be brightened as much as possible. At the same time, the load on the LED module 31 can be suppressed.

  The brightness plus mode may be combined with the eco lighting mode in step S10 and the illuminance sensor mode in step S12 in FIGS.

<Favorite registration mode>
Next, the favorite registration mode will be described.

  The favorite registration mode is a mode for registering the light control rate and the color tone.

  When the user presses the “favorite registration 1” button 71 or the “favorite registration 2” button 73 on the remote controller 50, the mode shifts to the favorite registration mode.

  Specifically, the current dimming rate and color tone are stored in a predetermined area of the memory 29. For example, in the above-described lighting adjustment mode and light environment control mode, the dimming rate and the color tone as shown in the graphs of FIGS. Also in this case, the current dimming rate and color tone are stored in a predetermined area of the memory 29.

  When the CPU 22 accepts an input instruction of the “favorite registration 1” button 71 or “favorite registration 2” button 73 of the remote controller 50 in a state where the dimming rate and the color tone are automatically and continuously changing as described above, The dimming rate and the color tone at the time when the instruction is received are written in a storage area corresponding to the favorite button in the memory 29. Thereby, the dimming rate and the color tone are registered for each of “favorite 1” and “favorite 2”.

  When the dimming rate and the color tone are written in a predetermined area of the memory 29 in response to an input instruction of the “favorite registration 1” button 71 or “favorite registration 2” button 73, the CPU 22 ends the operation of the favorite registration mode.

  If the lighting status such as the dimming rate or color tone is automatically changing continuously and the user cannot register when the lighting status is as desired, the user can operate the lighting status again by operating the remote control etc. Especially when you want to register the lighting state with two combinations of dimming rate and color tone, the operation to reproduce the lighting state is troublesome, and you can't remember the favorite lighting state you want to register May not be able to accurately reproduce the desired lighting state. In the present invention, it is not necessary for the user to reproduce the desired dimming rate or color tone again by remote control operation or the like, and the dimming rate or color tone desired to be registered while the lighting state is continuously changing automatically. When the “favorite registration 1” button 71 or “favorite registration 2” button 73 is pressed, information on the lighting state at the time of pressing can be registered, so that the user can easily and surely register the desired lighting state. For convenience.

  When the dimming rate and the color tone are already written in the corresponding storage area when the input instruction is received, overwriting may be performed according to this instruction. As default registration, a predetermined dimming rate and color tone (for example, favorite 1: daylight color 50%, light bulb color 50%, favorite 2: daylight color 100%, etc.) may be stored in advance.

  Preferably, the CPU 22 does not perform registration even if such an input instruction is accepted in the case of a predetermined dimming rate and color tone. Examples of the predetermined dimming rate and color tone include the dimming rate and color tone of the nightlight, and the dimming rate brighter than all the lights (100%) in the brightness plus mode. More preferably, when an input instruction of the “favorite registration 1” button 71 or the “favorite registration 2” button 73 is received in such a lighting state, the CPU 22 turns ON for 1 second / OFF for 0.5 seconds four times. A blinking display for notifying a registration error such as repetition is performed.

  When the CPU 22 receives an input of the “favorite 1” button 65 or the “favorite 2” button 72, the dimming rate and the dimming rate stored in the storage area of the memory 29 corresponding to “favorite 1” or “favorite 2”, respectively. Read out and set the color tone. Thus, when the user presses the “favorite 1” button 65 or “favorite 2” button 72 of the remote controller 50, the stored dimming rate and color tone can be set with one touch, which is convenient for the user. To serve.

  In addition, as described above, the lighting state information based on the dimming rate and the color tone registered in the memory 29 in the favorite registration mode is displayed when the “favorite 1” button 65 or the “favorite 2” button 72 is turned on and reproduced. Not only the use but also the lighting environment control mode can be used when setting the lighting state when lighting in my home setting or the on-timer mode.

  In the above example, the dimming rate and the color tone registered in “favorite 1” or “favorite 2” are stored in the memory 29 on the lighting device 1 side. However, the CPU 86 of the remote controller 50 may be stored in the memory 80 on the remote controller 50 side by operating in the same manner as the CPU 22 described above.

<Other processing>
As other processes, various functions can be executed in accordance with an input instruction from the remote controller 50.

  For example, the user can set the current daylight color or light bulb color dimming rate to 30% which is the nighttime dimming rate as time passes by pressing the “before sleep” button 66 of the remote controller 50. is there.

  Specifically, when there is an input instruction of the “before sleep” button 66 provided on the remote controller 50, the CPU 22 starts the before sleep mode and instructs the LED module 31 or LED to the PWM control circuit 23. An instruction is given to gradually adjust the PWM pulse S1 or S2 so that the dimming rate of the module 32 is 30%, which is the nighttime dimming rate. For example, the time when the “before sleep” button 66 is pressed is set as the start time, and the light control rate is set to 30% after 60 minutes in the same manner as described with reference to FIGS. 15 and 16.

  By using this function, when you want to advance the bedtime according to the user's preference, the dimming rate is gradually adjusted to darken, thereby reducing the level of human arousal and having a relationship with human biological rhythm. It is possible to promote a smooth sleep fall by promoting an increase in some melatonin secretion.

  Further, as described above, the user can set the current time in the lighting device 1 by pressing the “time setting” button 68 of the remote controller 50.

  In this example, an example of the function of the remote controller 50 has been described, and it is naturally possible to control the CPU 22 to realize a corresponding function by arranging buttons or the like for executing other functions. It is.

<LED module on / off control>
Next, lighting on / off control of the LED module according to the embodiment of the present invention will be described.

  The PWM control circuit 23 according to the embodiment of the present invention controls PWM pulses S1 and S2 output to the LED modules 31 and 32 in accordance with an instruction from the CPU 22. More specifically, the FET switch 33 is turned on according to the ON period of the PWM pulse S1, and the LED module 31 is lit. Further, the FET switch 33 becomes non-conductive according to the OFF period of the PWM pulse S1, and the LED module 31 is turned off.

  Similarly, the LED module 32 is turned on / off by the FET switch 34 being turned on / off in accordance with the PWM pulse S2 from the PWM control circuit 23.

  The CPU 22 is connected to a crystal oscillator 27 that outputs an oscillation signal of 40 MHz (one cycle 25 ns), and the PWM control circuit 23 outputs PWM pulses S1 and S2 in accordance with an instruction according to timing synchronized with the oscillation signal.

  FIG. 34 is a diagram illustrating generation of a PWM pulse output from the PWM control circuit 23 according to the embodiment of the present invention.

  Referring to FIG. 34, PWM pulses S1 and S2 output from PWM control circuit 23 are set according to the number of periods (here, Z) with one period 25 ns being the minimum unit of the oscillation signal as the minimum unit. The Here, the case where it sets about the lighting period Ton and the light extinction period Toff is shown.

  The lighting period Ton when the dimming rate is 100% is set with a certain margin so that the current supplied to the LED modules 31, 32, etc. does not exceed the rated current of the LED modules 31, 32, etc.

  Then, the cycle period T including the lighting period Ton and the extinguishing period Toff is set somewhat longer than the lighting period when the dimming rate is 100%. Therefore, for example, it is possible to set the lighting period Ton somewhat longer than the lighting period at which the dimming rate is 100%, and by supplying a current close to the rated current to the LED modules 31, 32, etc., 100% It is also possible to set the above dimming rate (brightness plus mode).

  FIG. 35 is a timing chart when adjusting PWM pulses S1, S2 output from PWM control circuit 23 according to the embodiment of the present invention.

  Referring to FIG. 35, the PWM control circuit 23 turns on and off the LED modules 31 and 32 in a complementary manner (that is, the on-duty of both is 100% in total), and the LED module 31. , 32 is set to have a turn-off period Toff that turns off both of them, and periodic lighting-off control of the LED modules 31, 32 is executed. The PWM control circuit 23 variably controls the ratio between the lighting period T1 of the LED module 31 and the lighting period T2 of the LED module 32 within the lighting period Ton.

  35A to 35D show the adjustment of the PWM pulses S1 and S2 in the early morning operation (period tA) in the light environment control.

  FIG. 35 (A) shows a case where the dimming rate is set to 30% only in the lighting period Ton of the PWM pulse S2 in the initial state. In this case, the PWM pulse S1 is always set to the “L” level. That is, the LED module 31 is in the off state.

  Then, as shown in FIGS. 35B to 35D, a case where the dimming rate is adjusted linearly by adjusting the duty ratio of the entire lighting period Ton (lighting period T1 + T2) in the period T is shown. ing.

  Further, the dimming rate of each LED with respect to the entire dimming rate is calculated based on the above-described formulas (6) and (7), and according to the calculation result, the lighting periods T1, T2 of the LED modules in the lighting period Ton. Is adjusted.

  Therefore, as described above, it is possible to adjust the dimming rate without causing the human to feel uncomfortable or uncomfortable by changing the overall dimming rate linearly according to the adjustment of the PWM pulse.

<Variation adjustment of LED module output characteristics>
In the above description, a case has been described in which the duty ratio of the entire lighting period Ton in the period T is adjusted to linearly change the dimming rate of the entire LED modules 31 and 32. However, the output characteristics of the LED modules 31 and 32 are described. May vary from the actual overall dimming rate due to variations in the light intensity.

  FIG. 36 is a diagram illustrating a change in the dimming rate of the LED modules 31 and 32 when the duty ratio of the lighting period Ton in the period T of the PWM pulse according to the embodiment of the present invention is adjusted.

  Referring to FIG. 36, ideally, it is desirable that the dimming rate change linearly when the duty ratio of the lighting period Ton in the period T of the PWM pulse is changed linearly. In general, the duty ratio of the PWM pulse is calculated according to a linear output characteristic line (ideal) where the dimming rate is 100% when the duty ratio of the PWM pulse is 100%.

  However, the output characteristic line of the dimming rate of the actual LED modules 31 and 32 is different from the ideal output characteristic line as shown in the figure.

  Therefore, in calculating the duty ratio of the PWM pulse according to the dimming rate, when the duty ratio is set by an ideal output characteristic line, there is a possibility that the dimming rate is different from the desired dimming rate. There is.

  FIG. 37 is a diagram illustrating the relationship between the dimming rate actually measured for the LED module 31 (daylight color LED) according to the embodiment of the present invention and the PWM pulse value.

  Referring to FIG. 37, here, an output characteristic line in the case where the vertical axis is the PWM pulse value (number of cycles) and the horizontal axis is the dimming rate (%) is shown.

  In this example, as an example, when the PWM pulse value is 1670, the duty ratio of the lighting period Ton is set to 100%.

  FIG. 38 is a diagram illustrating a relationship between the dimming rate actually measured for the LED module 32 (bulb color LED) and the PWM pulse value according to the embodiment of the present invention.

  Referring to FIG. 38, here, the output characteristic line when the vertical axis is the PWM pulse value (number of cycles) and the horizontal axis is the dimming rate (%) is shown.

  FIG. 39 is a diagram for explaining an approximate expression of the output characteristic lines of the LED modules 31 and 32.

  Referring to FIG. 39, an approximate expression of daylight color LED according to the output characteristic line of LED module 31 in FIG. 37 and an approximate expression of light bulb color LED according to the output characteristic line of LED module 32 in FIG. 38 are shown.

  Here, regarding the approximate expression of the daylight color LED, the case where the dimming rate according to the output characteristic line shown in FIG. 37 is divided into four areas and the approximate expression in each area is calculated is shown. As an example, “light control rate 0 to 60.0%”, “light control rate 60.1% to 91.0%”, “light control rate 91.1% to 98.0%”, “light control rate 98” .1% to 100.0% "is shown. Here, there is shown a case where the approximate expression is further transformed into an arithmetic expression in order to facilitate processing by the CPU 22. The CPU 22 can calculate a desired PWM pulse value according to the actual output characteristic line of the LED module 31 by inputting a desired dimming rate as a variable using the arithmetic expression.

  Similarly, regarding the approximate expression of the daylight color LED, the case where the dimming rate according to the output characteristic line shown in FIG. 38 is divided into four areas and the approximate expression in each area is calculated is shown. As an example, “light control rate 0 to 82.5%”, “light control rate 82.6% to 97.0%”, “light control rate 97.1% to 99.9%”, “light control rate 100” The case of dividing into “%” is shown. Here, there is shown a case where the approximate expression is further transformed into an arithmetic expression in order to facilitate processing by the CPU 22. The CPU 22 can calculate a desired PWM pulse value according to the actual output characteristic line of the LED module 32 by inputting a desired dimming rate as a variable using the arithmetic expression. In FIGS. 37 and 38, the approximate characteristic line using the arithmetic expression is indicated by a bold line.

  That is, it is possible to set a desired dimming rate by calculating a PWM pulse value corresponding to the dimming rate, that is, a duty ratio of the PWM pulse, based on the arithmetic expression. Therefore, it is possible to perform dimming with high accuracy, and it is possible to realize a more comfortable light environment in consideration of variations in output characteristics of the LED module.

  As shown in the output characteristic line of FIG. 38, the dimming rate is 100% before the PWM pulse value is 1670, that is, before the duty ratio of the lighting period Ton is 100%. ing.

  Therefore, in the approximate expression of FIG. 39, the approximate expression is calculated according to the output characteristic line until the dimming rate exceeds 100% up to the dimming rate of 99.9%. When the dimming rate is 100.0%, the PWM pulse value is 1670. That is, an approximate expression is calculated using only necessary output characteristic lines. Thereby, for example, in this example, it is not necessary to increase the value of the PWM pulse value unnecessarily, and the power consumption can be reduced by suppressing the duty ratio.

  FIG. 40 is a flowchart illustrating PWM pulse output in consideration of variations in output characteristics of LED module 31 according to the embodiment of the present invention.

  This flow is executed when the CPU 22 reads a program stored in the memory 29.

  Referring to FIG. 40, CPU 22 determines whether the dimming rate is in the range of 0% to 60.0% (step S70).

  Next, when the CPU 22 determines that the dimming rate is in the range of 0% to 60.0% (YES in step S70), the CPU 22 calculates the PWM pulse value based on the arithmetic expression (11). Then, a PWM pulse is output based on the calculated PWM pulse value. And it returns to step S70 again.

  If the CPU 22 determines that the dimming rate is not within the range of 0% to 60.0% (NO in step S70), then the dimming rate is 60.1% to 91.0%. It is determined whether it is within the range (step S76). In step S76, when the CPU 22 determines that the dimming rate is in the range of 60.1% to 91.0%, the CPU 22 calculates the PWM pulse value based on the arithmetic expression (12) (step S78). . Then, a PWM pulse is output based on the calculated PWM pulse value. And it returns to step S70 again.

  If the CPU 22 determines that the dimming rate is not within the range of 0% to 60.0% (NO in step S70), then the dimming rate is 91.1% to 98.0%. It is determined whether it is within the range (step S80). In step S80, when the CPU 22 determines that the dimming rate is in the range of 91.1% to 98.0%, the CPU 22 calculates the PWM pulse value based on the arithmetic expression (13). Then, a PWM pulse is output based on the calculated PWM pulse value. And it returns to step S70 again.

  If CPU 22 determines that the dimming rate is not within the range of 91.1% to 98.0% (NO in step S80), then the dimming rate is 98.1% to 100.0. It is judged whether it is in the range of% (step S84). In step S84, when the CPU 22 determines that the dimming rate is in the range of 98.1% to 100.0%, the CPU 22 calculates the PWM pulse value based on the arithmetic expression (14). Then, a PWM pulse is output based on the calculated PWM pulse value. And it returns to step S70 again. If the CPU 22 determines in step S84 that the dimming rate is not within the range of 98.1% to 100.0%, the process returns to step S70.

  In this example, the output of the PWM pulse S1 in consideration of the variation in the output characteristics of the LED module 31 has been described. However, the same method is executed for the output of the PWM pulse S2 in consideration of the variation in the output characteristics of the LED module 32. Is possible.

  As a result of the processing, the PWM pulse value corresponding to the dimming rate, that is, the duty ratio of the PWM pulse can be calculated based on the arithmetic expression as described above. It becomes possible to realize a more comfortable light environment in consideration of variations in output characteristics.

  In this example, the case where the approximate expression is calculated and the output of the PWM pulse in consideration of the variation in the output characteristics of the LED module has been described. However, the present invention is not particularly limited to this, for example, the output characteristic line described above. Accordingly, a correspondence table storing a one-to-one correspondence between PWM pulse values and dimming rates may be used.

  In the above description, the illumination device 1 includes the crystal oscillator 27, and the CPU 22 accurately measures the time according to the oscillation signal from the crystal oscillator 27 to perform control in the light environment control mode or the like. However, since the crystal oscillator 27 outputs an oscillation signal when a voltage is supplied from the power supply circuit 10, the CPU 22 is interrupted when the supply of voltage is interrupted by the operation of a power switch (not shown) included in the operation SW42. It becomes impossible to measure the time. In this case, the time measurement by the CPU 22 is resumed by adjusting the time when the voltage supply is started by the operation of the power switch next time, but the lighting device 1 is transmitted from the remote controller 50 by command transmission processing. May obtain the current time. Hereinafter, the command transmission process in the remote controller 50 will be described.

  FIG. 41 is a flowchart illustrating command transmission processing at remote controller 50 according to the embodiment of the present invention.

  It is assumed that the flow is executed by the CPU 86 reading a program stored in the memory 80.

  Referring to FIG. 41, when CPU 86 of remote controller 50 receives an input of an operation signal indicating that “light environment control” button 58 has been pressed (YES in step S200), signal transmission unit 84 receives light environment control mode. An instruction transmission signal (command) is output to the infrared light projector 87. At this time, the CPU 86 measures the time according to the oscillation signal from the crystal oscillator 85, and outputs a signal indicating the current time together with the command to the infrared light projector 87 (step S202).

  On the other hand, if “light environment control” button 58 has not been pressed (NO in step S200), it is next determined whether or not a timer instruction has been input (step S204).

  Specifically, it is determined whether or not there is an instruction input from any of the “Absolute Timer” button 67, “Off Timer” button 74, and “On Timer” button 75.

  Upon receiving an instruction input from the timer, that is, when an operation signal is input from any one of the “answer timer” button 67, the “off timer” button 74, and the “on timer” button 75 (NO in step S200 and YES in step S204). Then, the signal transmitter 84 causes the infrared light projector 87 to output a timer setting instruction transmission signal (command). The timer setting instruction shown here is an absence timer control instruction in the case of operation of the “absence timer” button 67 as described above, and in the case of operation of the “off timer” button 74, the off timer setting information. It is. Further, in the case of operation of the “on timer” button 75, it is on timer setting information. When the “off timer” button 74 and the “on timer” button 75 are operated for the first time, the operations for setting the off timer and the on timer are started, and the off timer setting screen and the on timer setting screen are displayed. Is done. Here, the instruction input of the timer relating to the “OFF timer” button 74 and the “ON timer” button 75 indicates the second operation of the “OFF timer” button 74 and the “ON timer” button 75.

  At this time, the CPU 86 measures the time according to the oscillation signal from the crystal oscillator 85, and outputs a signal indicating the current time together with the command to the infrared light projector 87 (step S206).

  When the input operation signal is neither an operation of the “light environment control” button 58 nor an instruction input of the timer (NO in step S200 and NO in step S204), the signal transmission unit 84 responds to the operation signal. A transmission signal (command) is output to the infrared light projector 87 (step S208). At this time, a signal indicating the current time is not output.

  Thereafter, the signal transmitter 84 outputs a transmission signal in accordance with an instruction from the CPU 86 to the infrared projector 87, and the infrared projector 87 outputs the infrared signal to the illumination device 1 (step S210).

  In addition, although this example assumes that the control mode in which the illumination state differs depending on the time among the control modes in the lighting device 1 is the light environment control mode and the timer mode, the other control modes depend on the time. When the illumination state is included in different control modes, a signal indicating the current time may be output together with the control command even when the mode is selected.

  In this example, the CPU 86 outputs a signal indicating the current time based on the oscillation signal from the crystal oscillator 85, but the remote controller 50 does not include the crystal oscillator 85 and the “time setting” button 68. Alternatively, a signal indicating the current time may be output based on the input of the time received by pressing the “UP” button 57A and / or the “DOWN” button 57B.

  This is the case where the voltage supply is cut off by the operation of the power switch of the lighting device 1 and the time measurement by the CPU 22 of the lighting device 1 becomes impossible, and the time information is required next. Even when the remote control 50 is instructed to start the operation, the mode is activated according to the time information from the remote controller 50 without performing an operation for adjusting the time on the lighting device 1.

  Further, in this operation, the time information is transmitted when instructing the start of the mode requiring the time information, and the information output from the remote controller 50 so that the time information is not transmitted when the instruction is not so. The amount can be reduced. Thereby, the power consumption in the remote control 50 required for communication can be suppressed.

  Note that it is also possible to provide a program that causes a computer to function and execute control as described in the above flow. Such a program can be read by a non-transitory computer such as a flexible disk attached to a computer, a CD-ROM (Compact Disk-Read Only Memory), a ROM (Read Only Memory), a RAM (Random Access Memory), and a memory card. It can be recorded on a recording medium and provided as a program product. Alternatively, the program can be provided by being recorded on a recording medium such as a hard disk built in the computer. A program can also be provided by downloading via a network.

  The program may be a program module that is provided as part of an operating system (OS) of a computer and that calls necessary modules in a predetermined arrangement at a predetermined timing to execute processing. In that case, the program itself does not include the module, and the process is executed in cooperation with the OS. A program that does not include such a module can also be included in the program according to the present invention.

  The program according to the present invention may be provided by being incorporated in a part of another program. Even in this case, the program itself does not include the module included in the other program, and the process is executed in cooperation with the other program. Such a program incorporated in another program can also be included in the program according to the present invention.

  The provided program product is installed in a program storage unit such as a hard disk and executed. The program product includes the program itself and a recording medium on which the program is recorded.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
