FIG. 1 is a diagram illustrating a lighting system 10 according to an example of an embodiment. FIG. 2 is a block diagram showing the configuration of the illumination system 10. In the example shown in FIG. 1, the lighting fixture 50 that configures the lighting system 10 is installed on the ceiling of the bedroom, but the lighting fixture 50 may be installed on the wall of the bedroom or the like. The lighting fixture 50 may be installed in a room other than the bedroom.

As shown in FIG. 2, the lighting system 10 includes a remote controller 20 having an operation unit 21, and a lighting fixture 50 operated by the remote controller 20. The remote controller 20 is a remote control device for operating the lighting fixture 50. The lighting fixture 50 is, for example, a ceiling light, receives AC power from the AC power supply 1, operates, and is capable of dimming and color adjustment. Specifically, the luminaire 50 includes a light source unit 51 that emits light that can be dimmed and toned, a power supply circuit 55 that supplies power from the AC power supply 1 to the light source unit 51, and a power supply circuit. An instrument-side control device 60 that controls the light source unit 51 via 55 is included. The device-side control device 60 is hereinafter referred to as the control device 60.

The light source unit 51 includes a first light source 52 and a second light source 53 which emit light of different colors. For example, the first light source 52 is a daylight color LED (Light Emitting Diode), and the second light source 53 is a light bulb color LED. For example, the color temperature of the first light source 52 is 6500K, and the color temperature of the second light source 53 is 2700K.

The power supply circuit 55 is controlled by a control signal from the control device 60 and supplies a current to the first light source 52 and the second light source 53. Specifically, the power supply circuit 55 is connected between the AC power supply 1 and the first light source 52 and the second light source 53. The power supply circuit 55 rectifies the AC voltage supplied from the AC power supply 1 into a DC voltage by the rectifier circuit, and converts the magnitude of the DC voltage by the DC-DC converter. The DC-DC converter is controlled by the control device 60. The DC-DC converter controls the current flowing through each of the light sources 52 and 53 by adjusting the voltage applied to each control terminal of the two transistors connected in series to each of the light sources 52 and 53. Therefore, the brightness and color temperature of the combined light from the light sources 52 and 53 are adjusted.

The storage unit 62 has a function of temporarily storing information and the like used in the processing of the control circuit 61, and a function of storing a control program, various setting information, and the like.

The storage unit 62 sets the combination of the color temperature and the brightness of the combined light of the first light source 52 and the second light source 53 to each of a first lighting mode, a second lighting mode, and a third lighting mode described later. Correlate and memorize. The first and third lighting modes are modes in which light adjustment and color adjustment can be performed, respectively. For this reason, the storage unit 62 associates the combination of the color temperature and the brightness of the combined light of the first light source 52 and the second light source 53 with the first and third lighting modes in association with each other. Store as a dimming and toning table. A plurality of operating points are set in each of the dimming and toning tables according to the dimming stage and the toning stage, and the combination of color temperature and brightness is stored corresponding to the operating point. At this time, in each of the dimming and toning tables, a combination of outputs of the first light source 52 and the second light source 53 is associated and defined as a dimming and toning output corresponding to each operating point. There is.

On the other hand, the second lighting mode is a mode in which only dimming at a predetermined color temperature can be performed. Therefore, the storage unit 62 stores the combination of the color temperature and the brightness of the combined light of the first light source 52 and the second light source 53 as a second dimming table in association with the second lighting mode. .. A plurality of operating points are set in the second dimming table according to the dimming stage, and a combination of color temperature and brightness is stored in correspondence with the operating points. At this time, in the second dimming table, a combination of respective outputs of the first light source 52 and the second light source 53 is defined as a dimming toning output in association with each operating point. ..

The input circuit 63 is a circuit that acquires a signal based on a user's operation instruction, and is, for example, a circuit that receives an infrared ray transmitted from the remote controller 20 and transmits a signal based on the infrared ray to the control device 60. The control circuit 61 controls the light source unit 51 so as to reproduce the combined light in the mode, color temperature and brightness based on the signal transmitted from the input circuit 63.

The remote controller 20 includes an operation unit 21 and a remote-control-side control device (not shown) that transmits an operation signal based on the operation of the operation unit 21. The operation unit 21 includes a plurality of operation buttons. The remote controller 20 transmits a signal instructing the lighting state of the light source unit 51 to the lighting fixture 50 according to the operation of the operation unit 21. As a result, the lighting fixture 50 is turned on according to the operation of the remote controller 20.

FIG. 3 is an enlarged front view of the remote controller 20. As shown in FIG. 3, the remote controller 20 includes an operation unit 21 and a display unit 25 arranged on the front surface (front surface) of the case 20a. The operation unit 21 has a plurality of buttons. The display unit 25 displays the current time, the set time of a timer or the like, the brightness level, and the like. The display unit 25 is, for example, a liquid crystal monitor. The shape and size of the remote controller, the shape, size, number, and arrangement of the buttons of the operation unit 21 and the display unit 25 are not particularly limited.

The plurality of buttons of the operation unit 21 are an all-light button 21a for instructing to turn on the light source unit 51 (FIG. 2) with a predetermined color temperature (for example, 6200K) and a combined light having a brightness of 100%, and A light-off button 21b for instructing to turn off the light source unit 51 that is on. The plurality of buttons also include a light control button 21c, a color control button 21d, and a lighting button 21e. The dimming button 21c is pressed down to instruct to increase the brightness, and pressed down to instruct to decrease the brightness. The toning button 21d is pressed down to instruct to increase the color temperature to approach a white color, and to press down to instruct to lower the color temperature to approach a warm color. The lighting button 21e instructs to light at a predetermined color temperature and brightness that can be set by the dimming button 21c and the toning button 21d. The plurality of buttons also includes a wake-up setting button 21f described later. The mode in which the light source unit 51 is turned on by operating the lighting button 21e and the lighting is operated by the light control button 21c and the color adjustment button 21d corresponds to the first lighting mode.

The all-light button 21a is also used to instruct the second lighting mode. Specifically, the light source section 51 is brought into a full-light state at a predetermined color temperature by depressing the full-light button 21a, and then the dimming button 21c is operated to perform dimming at the same color temperature as in full-light operation. It will be possible. At this time, even if the toning button 21d is pressed down, the lighting state of the light source unit 51 does not change depending on the operation. The second lighting mode has an operation area that cannot be output in the first lighting mode as described later.

The wake-up setting button 21f is used to instruct the third lighting mode. The wake-up setting button 21f is a button for instructing to continuously change the color temperature and brightness of the combined light of the light source unit 51 so that the user can comfortably wake up. By pressing down the wake-up setting button 21f, the light source unit 51 is turned on and the dimming and toning is started before the set time of the preset wake-up setting time. Then, the color temperature and the brightness of the combined light of the light source unit 51 continuously change toward the wake-up set time. At this time, the operation of the light source unit 51 shifts from the first operating point in the first lighting mode to the second operating point (all-light state) in the second lighting mode.

FIG. 4 shows that the dimming and toning operation is continuously performed between the first operating point and the second operating point at the time of getting up by using the time change of the brightness. In the example of FIG. 4, in order to allow the user to comfortably wake up at the preset wake-up setting time t2, the light source unit 51 is lit at a warm color temperature and dark at the lighting start time t1 before the set time ta from the time t2. The operation is performed at the first operation point as described above. Then, from that state, the dimming and toning is automatically performed, and the light source unit 51 is operated (lit) at the second operating point in the all-light state of white and bright colors at the wake-up setting time t2. , The toning fade function is executed. The remote controller 20 may have a button for setting the wake-up setting time t2 and the set time ta for starting lighting after pressing the wake-up setting button 21f.

The control device 60 has a function of executing the first lighting mode, the second lighting mode, and the third lighting mode as the lighting modes. The first lighting mode is a so-called normal mode. Specifically, the first lighting mode has an operation area for dimming and toning, and when the user presses a predetermined button on the operation unit 21, the lighting device 50 changes to a lighting state corresponding to the button. Become. For example, the lighting device 50 is turned on by pressing the lighting button 21e of the operation unit 21, and the lighting device 50 is gradually adjusted by operating the dimming button 21c of the operation unit 21, and the color adjustment button 21d of the operation unit 21 is operated. The lighting device 50 is controlled so as to be color-adjusted stepwise by the operation of. At this time, the lighting fixture 50 can perform the lighting operation at a point (or a point on the frame) in the frame of the quadrangle abcd shown in FIGS. 5 and 6 described later.

The second lighting mode has an operation area of only dimming, and when the user presses a predetermined button on the operation unit 21, the lighting fixture 50 corresponds to the button at a predetermined color temperature set in advance. Lights up. For example, after the all-light button 21a is pressed down, by operating the dimming button 21c, the lighting device 50 is controlled so as to be dimmed stepwise at the same color temperature as when all the lights are illuminated. For example, the lighting fixture 50 can perform a lighting operation in a range of a straight line mg (which may be the point m or the point f) shown in FIGS. 5 and 6 described later. In the second lighting mode, as shown in FIGS. 5 and 6 to be described later, an operation region in which the first lighting mode cannot output (between points f and g in FIGS. 5 and 6 (may be point g)). ) Has.

The third lighting mode includes a first operating point (point a in FIG. 6) preset in the first lighting mode and a second operating point (point g in FIG. 6) preset in the second lighting mode. It is a mode in which the dimming and toning operation is continuously performed during the period. The control device 60 executes the toning fade function in which the toning is continuously performed by executing the third lighting mode. In particular, in the embodiment, when the toning fade function is operating, the parameters are changed so that the dimming toning table used when executing the first lighting mode can output the second operating point of the second lighting mode. To do. The luminaire may have a plurality of types of light sources such as LEDs, fluorescent lamps, and incandescent lamps.

Next, with reference to FIG. 5, an inconvenience caused by the comparative example having no third lighting mode will be described. FIG. 5 shows that in the illumination system of the comparative example, both the dimming operation and the toning operation cannot be continuously performed at a part of the transition between the first operating point a and the second operating point g. , The color temperature and the dimming ratio are used.

The comparative example has a first lighting mode in which dimming and toning is performed within the frame of the quadrangle abcd shown in FIG. 5, and a second lighting mode in which dimming is performed within the range of the straight line eg shown in FIG. .. In such a comparative example, as in the case shown in FIG. 4, dimming is performed from the first operating point a in the first lighting mode to the second operating point g in the second lighting mode when waking up or the like. Sometimes you want to perform toning continuously. The first operating point a is an operating point having the darkest and lowest color temperature, and the second operating point g is an operating point having the same brightness and the same color temperature as those of all the lights. In the examples of FIGS. 5 and 6, the case where the color temperature of the first operating point a is 2700K and the dimming rate is 5% is shown, and the color temperature of the second operating point is 6200K and the dimming rate is 100%. Is shown.

In the above case, the second operating point g is an operating point that cannot be output in the first lighting mode. Therefore, in order to shift from the first operating point a to the second operating point g, for example, as shown by an arrow L1 in FIG. 5, the color temperature is the same as that of the second operating point g from the first operating point a. , Continuous dimming toning is performed so as to shift to the upper limit dimming point f on the second operating point g side of the quadrangle abcd. Then, as shown by an arrow L2 in FIG. 5, color adjustment is continuously performed from the point f to the second operating point g. At this time, the dimming and toning is performed on the arrow L1, but only the dimming is performed and the toning is not performed on the arrow L2. This causes the user to feel uncomfortable about the change in the lighting state. In the embodiment, in order to eliminate such an inconvenience, the dimming toning table used in the first lighting mode is changed and used during the operation of the toning fade function, as shown in FIG.

FIG. 6 shows that, in the lighting system of the example of the embodiment, both the dimming operation and the toning operation can be continuously performed at all transitions between the first operating point a and the second operating point g. , The color temperature and the dimming ratio are used. As shown in FIG. 6, the control device 60 uses the first dimming toning table used in the first lighting mode as the third dimming toning table used during the operation of the toning fade function to the second dimming toning table. The parameter is changed and used so that the second operating point g in the lighting mode can be output. The parameter is a coefficient for increasing or decreasing the dimming toning output in the combination of the color temperature and the brightness of the combined light.

For example, in the example of FIG. 6, in the range of operating points of the first lighting mode (rectangle abcd) representing the first dimming toning table, the dimming toning output in the combination of the color temperature and the brightness of the synthetic light Are set as coefficients K1 and K2 as a ratio (%) to the maximum output of each of the first light source 52 (FIG. 2) and the second light source 53 (FIG. 2). During the operation of the toning fade function, the coefficients K1 and K2 of each dimming toning output in the range of the operating point of the first lighting mode are changed so that the second operating point g of all lights can be output. For example, at the same color temperature as the second operating point g, the dimming toned output (first output) at the dimming upper limit point f in the operating point range of the first lighting mode is the dimming at the second operating point g. The coefficient α by which the first output is multiplied is calculated so as to match the toning output (second output). Then, by multiplying the coefficient α by the coefficients K1 and K2 of the dimming and toning output of each settable point in the operating point range of the first lighting mode, the operating point range of the third lighting mode ( By setting the quadrangle hijk), the third dimming toning table is set. At this time, in the dimming and toning output, if the ratio to the maximum output exceeds 100%, the actual output ratio is 100%. Further, at this time, the operating points a, e, and d at the lower limit of the dimming rate of 5% during lighting are also multiplied by the coefficient to move to the operating points h, m, and k, but the output changes. Is small, it can be considered that the operating points a, e, and d are substantially the same as the operating points h, m, and k. The range of the operating point of the third lighting mode includes the first operating point a and the second operating point g. Therefore, the control device 60 continuously performs both the dimming operation and the toning operation during the transition between the first operating point a and the second operating point g during the operation of the toning fade function. It becomes possible to execute. For example, when shifting from the first operating point a to the second operating point g, as shown by the arrow L3 in FIG. 6, the operating point h to the second operating point which are considered to be substantially the same as the first operating point a. The dimming and toning can be continuously performed so as to shift to g. When setting the third dimming and toning table, the output of each point on the lower side ad, which is the dimming lower limit in the operating point range of the first lighting mode, is not multiplied by the coefficient α and the operating point range is set. It may be a quadrangle aijd.

FIG. 7: is a figure corresponding to FIG. 6 which shows the more concrete example in the illumination system 10 of an example of embodiment. In FIG. 7, the horizontal axis represents the color-adjusting stage in which the number of stages increases from white color to warm color, and the vertical axis represents the dimming stage in which the number of stages increases from all lamps (100%) in the upper stage to turning off. Is shown. The quadrangle abcd in FIG. 7 showing the range of the operating point in the first lighting mode corresponds to the quadrangle abcd in FIG. In FIG. 7, the notation x:y means the ratio (%) of the respective dimming and toning outputs of the first light source 52 and the second light source 53 to the respective maximum outputs. For example, 100:0.5 means that the output of the first light source 52 is 100% and the output of the second light source 53 is 0.5%. Further, in FIG. 7, “white×1.15” indicates that the output of the first light source 52 is increased by 1.15 times, and “electricity×1.15” is by 1.15 times the output of the second light source 53. It shows that it did. Further, “white/electricity×1.15” indicates that the outputs of the first light source 52 and the second light source 53 are each multiplied by 1.15. In FIG. 7, if the output ratio of each of the light sources 52 and 53 is set to exceed 100%, the actual output ratio is set to 100%. Even with such a setting, there is no effect on the transition between the first operating point a and the second operating point g.

In FIG. 7, the range of the operating point of the third lighting mode used during the operation of the toning fade function is indicated by a square aijd. The upper side ij of the quadrangle aijd on the all-lamp side of FIG. Each is multiplied by 1.15 to match g. In this example, the output ratio of the second light source 53 in the toning stage 0 and the output ratio of the first light source 52 in the toning stage 100 are each 0.5%. The ratio of the output of the second light source 53 in the toning stage 0 of the quadrangle abcd to the output of the first light source 52 in the toning stage 100 may be 0.

In addition, the above-described embodiment can be appropriately modified in design within a range that does not impair the object of the present disclosure. For example, the lighting state of the lighting device 50 may be operated using a device other than the remote controller 20, such as a smartphone or a tablet terminal. In addition, an operation unit may be connected to the control circuit 61 via a cable, and the operation unit may operate the lighting state of the lighting fixture 50. Further, in the above description, the case where the first operating point of the first lighting mode shifts to the second operating point of the second lighting mode at the time of executing the toning fade function has been described. The same can be done when shifting to the operating point. For example, the configuration may be such that the dimming and toning is continuously performed from the second operating point g of all the lights to the first operating point a that is a lighting state of a dark and warm color.
