Description

  The present invention relates to an illuminating device and an illuminating system including the illuminating device, and more particularly to an illuminating device and an illuminating system that can turn on a light source in a desired lighting state by turning on / off a power switch.

  A lighting device (lighting fixture) installed on an indoor ceiling or wall is turned on or off by operating a power switch provided on the wall, an operation cord drawn from the lighting fixture, an infrared remote controller, or the like. be able to. In addition, lighting fixtures having a dimming function capable of adjusting the brightness of the light source according to the user's preference, the installation location of the lighting fixture or the time zone are also widely used.

As a method of dimming a lighting fixture, for example, when a power switch provided on an indoor wall is operated and the power switch is in an on state, when the power switch is turned off for a short time, lighting is performed. There is a method of switching the brightness of an appliance (see Patent Document 1).
JP-A 63-271895

  In the luminaire of Patent Document 1, whether or not the power switch is turned off for a short time is determined using a timer (counter) provided in the microcomputer. However, since the timer provided in the microcomputer has an error of about ± 5%, for example, the timer built in each lighting device may vary. For this reason, for example, when controlling a plurality of lighting fixtures with a single power switch, although the power switch is turned off for a short time, the short-time power off state cannot be detected due to variations in the timer, and the predetermined brightness There was a problem that lighting fixtures that could not be switched appeared.

  FIG. 9 is an explanatory diagram showing an outline of a dimming method by operating a conventional power switch. In the example of FIG. 9, a plurality of lighting fixtures A to E can be turned on, dimmed (brightness switching), and turned off with one power switch (for example, a power switch provided on an indoor wall). is there. In FIG. 9, the shaded portion indicates the extinction ratio in a schematic manner. As shown in FIG. 9, it is assumed that all lighting fixtures are initially turned on with all lamps (100% brightness) and switched to 75% dimming by performing a power-off operation for a short time.

  Next, in order to change from 75% dimming to 50% dimming, when the power was turned off again for a short time, the built-in microcomputer (timer) in the lighting fixture D detected a short time power off state. Suppose you couldn't. In this state, although the other lighting fixtures except the lighting fixture D are turned on at 50% dimming, the lighting fixture D is turned on at 75%, which is the previous dimming mode. It falls into the situation that the level is not synchronized.

  In this state, the brightness of each lighting fixture is switched by performing a power-off operation for a short time again. That is, the other lighting fixtures except for the lighting fixture D are turned on from 50% dimming to 25% dimming, but the lighting fixture D is switched from the previous dimming mode of 75% to 50% dimming. The situation continues that the dimming level of the entire lighting fixture is not synchronized. As described above, when dimming control of a plurality of lighting fixtures is performed, once a situation occurs in which it is impossible to detect a short-time power-off state with one lighting fixture, the dimming levels of all the lighting fixtures are the same level. In addition, it was difficult to adjust the light control level. Such a lighting environment gives an uncomfortable feeling or an uncomfortable feeling to the user, and it has been desired to improve such a situation.

  This invention is made | formed in view of such a situation, and it aims at providing an illuminating device which can light a light source in a desired lighting state, and an illuminating system provided with this illuminating device.

  An illumination device according to the present invention includes a control unit that controls a lighting state of each of the plurality of light sources in each of the plurality of light sources, and each of the control units determines a lighting state of the plurality of light sources. Synchronizing means for synchronizing is provided.

  The illumination device according to the present invention includes a control unit that independently controls lighting states of a plurality of light sources, and the control unit corresponds to a first elapsed time from a power-off state to an on-state. In the lighting device that switches the lighting state of the light source, the control unit determines the lighting state of the plurality of light sources when a second elapsed time from the power-on state to the power-off state has passed a predetermined time. It is characterized by being synchronized.

  A lighting device according to the present invention includes a detection unit that detects a power on / off state, a first time counting unit that measures a first elapsed time from the power off state to the on state, and a power on state. And a second time measuring unit for measuring a second elapsed time from when it is turned off to when it is turned off.

  In the illumination device according to the present invention, the control unit controls the light source to a predetermined lighting state when the second elapsed time is longer than a second threshold and the first elapsed time is shorter than the first threshold. It is comprised by these.

  The illumination device according to the present invention includes a storage unit that stores transition information between different lighting states of the light source, and the control unit includes the first elapsed time when the second elapsed time is shorter than the second threshold. Is shorter than the first threshold value, the light source is controlled to be turned on in the lighting state transitioned according to the transition information stored from the latest lighting state.

  In the illumination device according to the present invention, the control unit is configured to control to turn on the light source in the most recent lighting state when the first elapsed time is longer than the first threshold. .

  An illumination system according to the present invention includes a plurality of illumination devices according to any one of the above-described inventions, and an operation unit for operating on / off of a power source that supplies power to each illumination device. It is configured to control the lighting state of the light source of each lighting device according to the operation.

  In the present invention, a control unit is provided corresponding to each of the plurality of light sources, and each control unit includes synchronization means for synchronizing the lighting states of the plurality of light sources. The lighting state is, for example, a full lighting state, a predetermined dimming mode, or the like, and the lighting state of all the light sources can be made the same by the synchronization means. Thereby, the light source can be turned on in a desired lighting state.

  In the present invention, the lighting device is in the lighting state of the plurality of light sources when the second elapsed time from the power-on state (on state) to the off state (off state) has passed a predetermined time. Synchronize. The lighting state is, for example, a full lighting state, a predetermined dimming mode, or the like. By taking into account the second elapsed time from when the power is turned on to when it is turned off, the light source can be synchronized with the desired lighting state only by turning on / off the power switch. Note that synchronizing means making the lighting states of a plurality of light sources the same. For example, when a predetermined first elapsed time is detected by operating the power switch, the lighting state of the light source is switched (for example, the dimming mode is switched), and then the second elapsed time is determined by turning on / off the power switch. When the time elapses, the plurality of light sources can be synchronized with a predetermined lighting state (for example, all lighting states, a predetermined dimming mode, etc.). Thereby, when lighting control of a plurality of lighting devices is performed by turning on / off one power switch, the lighting state of the entire lighting device can be set to a predetermined lighting state, so that the dimming level of the entire lighting device is temporarily Even when a situation where they are not the same occurs, the dimming levels of all the lighting devices can be easily aligned.

  In the present invention, the lighting device has a second elapsed time from the power-on state (on state) to the off state (off state) and a first elapsed time from the power-off state to the on state. The lighting state of the light source is controlled accordingly. That is, not only the time when the power is turned off (first elapsed time) but also the second elapsed time from when the power is turned on to when the power is turned off, the light source can be turned on only by turning on / off the power switch. It can be controlled to a desired lighting state. For example, when a predetermined first elapsed time is detected by operating a power switch, if the second elapsed time is shorter than a predetermined threshold time, the lighting state is switched as in the past (for example, the dimming mode is changed). When the second elapsed time is longer than a predetermined threshold time, it is possible to control to a predetermined lighting state (for example, a full lighting state, a predetermined dimming mode, etc.). Thereby, when lighting control of a plurality of lighting devices is performed by turning on / off one power switch, the lighting state of the entire lighting device can be set to a predetermined lighting state, so that the dimming level of the entire lighting device is temporarily Even when a situation where they are not the same occurs, the dimming levels of all the lighting devices can be easily aligned.

  In the present invention, when the second elapsed time is longer than the second threshold (for example, 10 seconds) and the first elapsed time is shorter than the first threshold (for example, 2 seconds), the lighting device turns on the light source. Control to a predetermined lighting state. The predetermined lighting state may be all the lights (100% dimming) or the dimming state such as 80% or 50% as long as the lighting states of the respective lighting devices are the same. Thus, when the power switch is operated and the power is turned on, for example, when the power is turned on after a short-time operation (for example, within 2 seconds) after a lapse of 10 seconds or more. The lighting state of each lighting device is unified to a predetermined lighting state, and even if the dimming level does not match, the lighting state of all lighting devices is aligned (synchronized). Can).

  In this invention, the illuminating device has memorize | stored the transition information between the lighting states from which a light source differs. The transition information is, for example, the switching order of each dimming mode including all lamps. When the second elapsed time is shorter than the second threshold (for example, 10 seconds) and the first elapsed time is shorter than the first threshold (for example, 2 seconds), the lighting device stores the transition information stored from the latest lighting state. The light source is turned on in the lighting state transitioned according to. Accordingly, when the power switch is operated and the power is turned on, for example, when the power is turned on after a short-time operation (for example, within 2 seconds) within 10 seconds, The lighting state of the lighting device can be switched according to a predetermined order. Further, by repeating the power-on operation after the power-off operation for a short time (for example, within 2 seconds), the lighting state of the lighting device can be sequentially switched and can be easily set to a desired lighting state. it can.

  In the present invention, when the first elapsed time is longer than the first threshold (for example, 2 seconds), the lighting device turns on the light source in the latest lighting state (previous lighting state). As a result, when the power switch is operated, for example, when the power is turned off when the power is turned off after 2 seconds, the light source is turned on while maintaining the lighting state before lighting. Can do.

  In the present invention, a plurality of illumination devices are provided by controlling the lighting state of the light source of each illumination device in accordance with an operation at an operation unit for operating on / off of power supplied to each illumination device. In this case, each lighting device can be controlled to a desired lighting state.

  According to the present invention, the light source can be turned on in a desired lighting state by performing on / off operation of the power switch, and lighting control is performed when lighting control of a plurality of lighting devices is performed by turning on / off one power switch. Since the lighting state of the entire device can be set to a predetermined lighting state, even if the lighting control level of the entire lighting device does not become the same, it is possible to easily adjust the lighting control levels of all the lighting devices. it can.

  Hereinafter, the present invention will be described with reference to the drawings illustrating embodiments thereof. FIG. 1 is an explanatory diagram showing an outline of an illumination system including an illumination device 100 according to the present invention, and FIG. 2 is a block diagram showing an example of the configuration of the illumination device 100 according to the present invention. As shown in FIG. 1, a lighting system according to the present invention includes, for example, a plurality of lighting devices (lighting fixtures) 100 installed on a ceiling or a wall in a room, and a commercial power source 1 that supplies power to each lighting device 100 (for example, And a power switch 2 for operating on / off of AC100V, AC200V). The power switch 2 is installed, for example, on a wall in a room, and can control lighting states such as lighting, dimming, and extinguishing of each lighting device 100 with one power switch 2. Although not illustrated in FIG. 1, a plurality of power switches 2,... May be provided, and the lighting states of the plurality of lighting devices 100 may be controlled by the power switches 2.

  The illuminating device 100 is connected to, for example, an AC 100V commercial power source, and includes a power source unit 10, a control unit 20, a plurality of LED modules 30 as a light source, and the like. The number or specification of the LED modules 30 can be appropriately set according to the specification, shape, etc. of the lighting device 100. Moreover, as a light source, it is not limited to the LED module 30, The structure using other light sources, such as a fluorescent lamp and an incandescent lamp, may be sufficient.

  The power supply unit 10 includes a fuse 11, a rectifier circuit 12, a noise filter circuit 13, a switching circuit 14, a switching transformer 15, a constant current supply circuit 16, a load current voltage detection circuit 17, a photocoupler 18, a protection circuit 19, and the like. .

  The fuse 11 is for interrupting an overcurrent of a predetermined value or more in order to protect the device when an abnormality such as a short circuit occurs in the device. The rectifier circuit 12 performs full-wave rectification on the AC 100V and converts it into direct current. The noise filter circuit 13 blocks, for example, noise that enters the lighting device 100 through a power supply line connected to a commercial power supply.

  The switching circuit 14 is composed of, for example, a transistor or an FET, and performs an operation of switching at a predetermined frequency (for example, an operation of alternately turning on / off a pair of transistors), whereby an alternating voltage is applied to the switching transformer 15. Supply. The switching transformer 15 outputs an alternating voltage converted into a predetermined voltage value according to the operation of the switching circuit 14.

  The constant current supply circuit 16 includes a rectifier circuit, a transistor, an operational amplifier, and the like, converts the alternating voltage supplied from the switching transformer 15 into a DC voltage (for example, 33 V), and controls the output current to be constant. .

  The load current voltage detection circuit 17 detects the current and voltage supplied by the constant current supply circuit 16 and outputs a control signal corresponding to the detected value to the protection circuit 19 through the photocoupler 18. The photocoupler 18 is for electrically insulating the primary side and the secondary side of the switching transformer 15. The protection circuit 19 controls the switching operation of the switching circuit 14 according to the control signal input from the load current voltage detection circuit 17. Thereby, the output value is fed back, and a constant current and voltage can be output.

  The PWM control circuit 23 controls the current supplied to each LED module 30 by performing pulse width modulation on the DC voltage output from the constant current supply circuit 16. More specifically, the control microcomputer 22 transmits a mode signal corresponding to a dimming level corresponding to a plurality of illumination states described later to the PWM control circuit 23, and the PWM control circuit 23 responds to the received mode signal. PWM control is performed for each LED module 30. In addition, the structure which each provides PWM control circuit 23 ... with respect to each LED module 30 may be sufficient.

  The control power supply circuit 21 converts the DC voltage output from the constant current supply circuit 16 into a predetermined voltage (for example, 5 V, 3.3 V, etc.), and supplies the converted voltage to the control microcomputer 22.

  FIG. 3 is a block diagram showing an example of the configuration of the control power supply circuit 21. The control power supply circuit 21 includes a capacitor 211, a three-terminal regulator 212, 213, a fuse 214, a capacitor 215, a Zener diode 216, and the like. The capacitor 211 protects the circuit by absorbing the overvoltage or noise when a transient overvoltage, noise, or the like occurs in the voltage supplied from the constant current supply circuit 16.

  The three-terminal regulators 212 and 213 convert the voltage supplied from the constant current supply circuit 16 into a predetermined voltage. Note that the number of the three-terminal regulators 212 and 213 is not limited to two.

  The fuse 214 is used to prevent the control microcomputer 22 from being damaged due to an overcurrent or an overvoltage being applied to the control microcomputer 22 when, for example, a short circuit between the terminals of the three-terminal regulators 212 and 213 occurs. Cut off the overcurrent.

  The capacitor 215 and the Zener diode 216 absorb an overvoltage or noise superimposed on the voltage input to the control microcomputer 22 to prevent malfunction or failure of the control microcomputer 22.

  The power supply state detection circuit 24 includes a pair of photocouplers, detects the presence or absence of AC 100 V supplied to the lighting device 100, and outputs the detection result to the control microcomputer 22.

  The infrared remote control light receiving unit 26 receives infrared light from a remote control body (not shown) operated by the user, extracts a signal transmitted from the remote control body, and outputs the extracted signal to the control microcomputer 22. The signal transmitted from the remote control body is, for example, for turning on, turning off, and dimming the light source. The AC 100 supplied to the lighting device 100 is not turned on / off by a signal transmitted from the remote control body.

  The memory 25 stores data necessary for the control microcomputer 22 to perform predetermined processing, and also stores processing results and the like. The memory 25 has, for example, a preset dimming mode (for example, mode 0 is full lighting, mode 1 is 80% dimming, mode 2 is 50% dimming, mode 3 is 25% dimming, etc.) Mode switching order (lighting state transition information, eg, mode 0, mode 1, mode 2, mode 3, mode 0), dimming mode at the time of the last (most recent) lighting, etc. is doing.

  The control microcomputer 22 includes an internal detection unit for detecting a power on / off state, an on-time timer (10-second timer) as a second timer for measuring the second elapsed time, and a first elapsed time. An off-time timer (2-second timer) as a first timekeeping unit is provided. The on-time timer starts counting when the power is turned on (on) by the power state detection circuit 24 (the on-time timer is set and turned on), and the on-time timer is turned off when 10 seconds have elapsed. To do. The off-time timer starts counting when the power is turned off (turned off) by the power state detection circuit 24 (the off-time timer is set and turned on), and the off-time timer is reached when 2 seconds have elapsed. Turn off. Note that the count times of the on-time timer and the off-time timer are not limited to 10 seconds and 2 seconds, respectively.

  The control microcomputer 22 counts based on the detection result detected by the power supply state detection circuit 24, the time from the power-on state to the off-state, the time from the power-off state to the on-state, and The lighting state of each LED module 30 is controlled according to the information stored in the memory 25.

  More specifically, the control microcomputer 22 is configured to turn on the power supply when the time from when the power is turned on to when the power is turned on last is longer than, for example, 10 seconds. For example, when the time from the OFF state to the ON state is shorter than 2 seconds, each LED module 30 is lit in a predetermined lighting state. Here, the predetermined lighting state may be all lamps (mode 0) or dimming states such as modes 1, 2, and 3 as long as the lighting states of the respective lighting devices 100 are the same. Thus, when the power switch 2 is operated and the power is turned on, for example, when the power is turned on after a short time (for example, within 2 seconds) of power-off after 10 seconds or more have elapsed. The lighting state of each lighting device 100 is unified to a predetermined lighting state, and even if the dimming level is not uniform, the lighting state of all the lighting devices is made uniform by eliminating such a situation. (Synchronized). That is, the control microcomputer 22 which is the control unit of the present invention detects the time (in the present invention, 10 seconds) from when the power source is turned on to when it is turned off, and turns on the lighting device in a predetermined lighting state. It becomes a synchronizing means which controls to a state and synchronizes a some illuminating device. Moreover, even if it becomes a situation where the dimming level of any of the lighting devices is not uniform due to a transient malfunction as in the prior art, the power switch 2 is operated and the power is turned on. For example, by turning on the power after a short time (for example, within 2 seconds) of turning off the power when 10 seconds or more have elapsed, the dimming levels of all the lighting devices can be made to be in the same state. It becomes possible.

  Further, the control microcomputer 22 starts from the power-off state when the time from when the power is turned on to when it is last turned off is shorter than, for example, 10 seconds. For example, when the time until the ON state is shorter than 2 seconds, each LED module 30 is lit in a mode shifted from the most recent (previous) mode (lighting state). Thereby, when the power switch 2 is operated and the power is turned on, for example, when the power is turned on after a power-off operation within a short time (for example, within 2 seconds) within 10 seconds, The lighting state of each lighting device 100 can be switched according to a predetermined order. Moreover, the lighting state of the lighting device 100 can be sequentially switched by repeating the power-on operation after the power-off operation for a short time (for example, within 2 seconds), and can be easily set to a desired lighting state. Can do.

  In addition, when the power source is turned on and the time from when the power source is turned off to when the power source is turned on last time is longer than 2 seconds, for example, the control microcomputer 22 is in the most recent (previous) mode. Each LED module 30 is turned on. As a result, when the power switch 2 is operated, for example, when the power is turned off when the power is turned off after 2 seconds or more, the light source is turned on while maintaining the lighting state before lighting. be able to.

  Next, the operation of the control microcomputer 22 will be described. FIG. 4 is a timing chart showing switching of the lighting state of the lighting device 100. In FIG. 4, arrows with “2 seconds” and “10 seconds” indicate periods in which the 2-second timer (off-time timer) and the 10-second timer (on-time timer) are on, respectively.

  It is assumed that the power switch 2 is operated at time t1, the power is turned on, and the lighting device 100 is turned on. The dimming mode at the time of lighting at time t1 may be any one, but is assumed to be mode 1 (80% dimming). At time t1, a 10 second timer (on-time timer) is set and turned on.

  Next, it is assumed that the power switch 2 is operated at time t2 to turn off the power, and then the power is turned on at time t3. In this case, a 2-second timer (off-time timer) is set and turned on at time t2. At time t3, since the 10-second timer set at time t1, which is the most recent power-on timing, is on and the 2-second timer is on, the control microcomputer 22 operates in the previous mode (mode 1). Each LED module 30 is turned on in a mode (for example, mode 2) transitioned from. At time t3, the 10-second timer (on-time timer) is once reset, set again, and turned on.

  Next, it is assumed that the power switch 2 is operated at time t4 to turn off the power, and then the power is turned on at time t5. In this case, a 2-second timer (off-time timer) is set and turned on at time t4. At time t5, since the 10-second timer set at time t3, which is the most recent power-on timing, is off and the 2-second timer is on, the control microcomputer 22 resets the mode (for example, In the mode 0), each LED module 30 is turned on. At time t5, the 10-second timer is set and turned on.

  Next, assume that the power switch 2 is operated at time t6 to turn off the power, and then the power is turned on at time t7. In this case, a 2-second timer (off-time timer) is set and turned on at time t6. Since the 2-second timer is off at time t7, the control microcomputer 22 operates in the previous mode (lights on) regardless of the 10-second timer on / off set at time t5, which is the most recent power-on timing. Each LED module 30 is turned on in the previous mode 0). At time t7, the 10-second timer (on-time timer) is once reset, set again, and turned on.

  Next, it is assumed that the power switch 2 is operated at time t8 to turn off the power, and then the power is turned on at time t9. In this case, a 2-second timer (off-time timer) is set and turned on at time t8. Since the 2-second timer is off at time t9, the control microcomputer 22 operates in the previous mode (lights on) regardless of the on / off state of the 10-second timer set at time t7, which is the most recent power-on timing. Each LED module 30 is turned on in the previous mode 0). At time t9, the 10-second timer is set and turned on. Thereafter, the same operation is repeated.

  5 and 6 are explanatory diagrams showing the relationship between the operating state of the illumination device 100 and the state change factors. 5 and 6, the horizontal column indicates the operating state before the change, and the vertical column indicates the change factor. In the figure, the hatched column indicates a case where there is no operation state. For example, if 10 seconds or more have passed since the last (previous) power on (10 seconds) (10 seconds timer off), and 2 seconds or more have passed since the power was turned off (off) (2 seconds timer off), the power is turned on (on). In the mode, the LED module 30 is turned on and the 10-second timer is turned on.

  In addition, when the power is turned on (on) after 10 seconds have passed since the last (previous) power on (on) (10 seconds timer off) and within 2 seconds (2 seconds timer on) after power off (off), mode 0 Then, the LED module 30 is turned on (reset operation) and the 10-second timer is turned on. In this case, the 2-second timer remains on. Also, more than 10 seconds have passed since the last (previous) power-on (on) (10-second timer off), and within 2 seconds (2-second timer on) from power-off (off). If more than one second has elapsed, the 2-second timer is turned from on to off.

  Also, when the power is turned on (on) within 10 seconds after the last (last time) power on (on) (10 second timer on) and more than 2 seconds have passed since power off (off) (2 seconds timer off), the previous mode As a result, the LED module 30 is turned on. Also, within 10 seconds from the last (previous) power-on (on) (10-second timer on) and more than 2 seconds after power-off (off) (2-second timer off), from the last power-on When 10 seconds or more have elapsed, the 10-second timer is turned off from on.

  Also, if the power is turned on (on) within 10 seconds after the last (previous) power on (10 seconds timer on), and within 2 seconds (2 seconds timer on) after power off (off), the mode is changed from the previous time. The LED module 30 is turned on after the transition. Also, within 2 seconds (2 seconds timer on) within 10 seconds (10 seconds timer on) from the last (previous) power on (on) and 2 seconds (2 seconds timer on) from the last power off. If more than one second has elapsed, the 2-second timer is turned from on to off. Furthermore, within 10 seconds after the last (previous) power-on (on) (10-second timer on) and within 2 seconds (2-second timer on) after power-off (off), 10 If more than one second has elapsed, the 10-second timer is turned from on to off.

  In addition, when the LED module 30 is turned on in mode 0 and the power is turned off with both the 2-second timer and the 10-second timer turned off, the LED module 30 is turned off and the 2-second timer is turned on. .

  In addition, when the LED module 30 is turned on in mode 0, the 2-second timer is off, and when the 10-second timer is on and the power is turned off (off), the LED module 30 is turned off and 2 seconds. The timer is turned on. In addition, when the LED module 30 is turned on in mode 0, the 2-second timer is off, the 10-second timer is on, and 10 seconds or more have passed since the last power-on, the 10-second timer is Turn from on to off.

  In addition, the LED module 30 is turned on in mode 0, and the LED module 30 is turned off when the 2-second timer and the 10-second timer are both on and the power is turned off. In addition, when the LED module 30 is lit in mode 0 and both the 2-second timer and the 10-second timer are on, and the 2-second timer has passed since the last power-off, the 2-second timer is turned from on to off. Become. Further, the case where the LED module 30 is lit in modes 1, 2, and 3 is the same as in the case of mode 0.

  FIG. 7 is an explanatory diagram showing the transition state of the lighting state. As shown in FIG. 7, the lighting state of the LED module 30 is mode 0 (all lights), mode 1 (80% dimming), mode 2 (50% dimming), mode 3 (25% dimming), and off. There are five modes. Note that the number of modes, the dimming ratio, and the like are examples, and are not limited thereto. In addition, the mode transition order circulates as mode 0, mode 1, mode 2, mode 3, and mode 0.

  As shown in FIG. 7, in the case of a mode reset operation, that is, when the power is turned on (on) with the 10-second timer (on-time timer) off and the 2-second timer (off-time timer) on. In the mode 0, the LED module 30 is lit.

  Further, in the case of a mode change operation, that is, when the 10 second timer (on-time timer) is on and the 2-second timer (off-time timer) is also on, the power is turned on (on). The LED module 30 lights up according to the transition order.

  Further, when the lighting operation is performed in the previous mode, that is, when the power is turned on (on) with the 2-second timer (off time timer) being off, the LED module 30 is operated in the same mode as the previous mode. Light.

  FIG. 8 is a flowchart showing a processing procedure of the control microcomputer 22. The control microcomputer (hereinafter referred to as “microcomputer”) 22 determines whether or not the power switch is turned on (S11). If the power switch is not turned on (NO in S11), step S11 is performed. Continue processing. If the power switch is on (YES in S11), it is determined whether or not the off-time timer (2-second timer) is on (S12).

  If the off-time timer (2-second timer) is not on (NO in S12), that is, if it is off, the microcomputer 22 lights the LED module 30 in the previous mode (S13). If the off-time timer (2-second timer) is on (YES in S12), the microcomputer 22 determines whether the on-time timer (10-second timer) is on (S14).

  When the on-time timer (10-second timer) is on (YES in S14), the microcomputer 22 changes the mode and lights the LED module 30 (S15), and the on-time timer (10-second timer) is not on. (NO in S14), that is, if it is off, the LED module 30 is lit in the reset mode (S16).

  The microcomputer 22 sets an on-time timer (10-second timer) (S17). If the on-time timer is on, it is reset and set (turned on) again. The microcomputer 22 determines whether or not the power switch is turned off (S18) (S18). If the power switch is not turned off (NO in S18), the process of Step S18 is continued.

  When the power switch is turned off (YES in S18), the microcomputer 22 turns off the LED module 30 (S19), sets an off-time timer (2-second timer) (S20), and performs the processing after step S11. to continue. If the off-time timer is on, it is reset and set (turned on) again. In addition, although the above-mentioned process determines the on / off of the power switch 2 and indicates the process based on the determination result, it is basically an infinite loop process.

  As described above, in the present invention, not only simply detecting a short-time power-off operation as in the prior art, but also by taking into account the elapsed time from the power-on state to the off-state. When the light source can be brought into a predetermined lighting state (lighting state in the reset mode) only by turning on / off the power switch, and the lighting device is controlled by turning on / off one power switch, the lighting device Since the entire lighting state can be set to a predetermined lighting state, even if a situation occurs in which the dimming level of the entire lighting device is not the same, the lighting state and dimming level of all the lighting devices can be easily aligned. be able to.

  In addition, there are cases where a plurality of lighting devices installed on the ceiling or the like are individually controlled by a remote controller, for example, to control the lighting state at the dimming level, and the lighting state becomes mixed. In that case, in order to align the dimming levels of a plurality of lighting devices using a remote controller, remote control operation is required for each lighting device, whereas according to the present invention, the power switch The lighting state can be easily aligned (synchronized) by the on / off operation. That is, after a predetermined time (10 seconds in the present invention) elapses after the power switches of a plurality of lighting devices are turned on, the power switch is turned on and off within a predetermined time (2 seconds in the present invention). Thus, it is possible to easily align (synchronize) the illumination states of the plurality of illumination devices.

  In the above-described embodiment, the lighting states (all lighting states or dimming levels) of a plurality of lighting devices are arranged (synchronized). However, the present invention is not limited to this, and a plurality of lighting devices is used. It is also possible to align (synchronize) the light colors of the light sources.

  The lighting states with different light colors may be, for example, lighting states (lighting states) with different color temperatures such as light bulb color, daylight white, daylight color, or illumination states with different chromaticities such as blue, green, and red. . Even when the plurality of illumination states are in different illumination states due to remote control operations or microcomputer timer variations, the power switches of the plurality of illumination devices are turned on for a predetermined time (for example, 10). After the elapse of seconds, the lighting state of each of the plurality of lighting devices can be easily aligned (synchronized) by performing a power switch on / off operation within a predetermined time (for example, 2 seconds).

  In the above-described embodiment, each of the plurality of lighting devices includes a microcomputer that is a control unit that controls the lighting state of each lighting device independently. However, a plurality of light source units are included in one lighting device. And a lighting device having a control unit such as a microcomputer for controlling each light source unit for each of the plurality of light source units. In this case, even if a plurality of light sources in the illumination device are in different illumination states, the illumination states can be synchronized by turning on / off the power switch.

  In the above-described embodiment, the dimming is performed by controlling the current of each LED module. However, the present invention is not limited to this, and the entire lighting device is dimmed by turning off some of the LED modules. You may make it perform light.
