Description

  The present invention relates to an illumination control system capable of mixing illumination light from light sources having different emission colors to obtain illumination light and changing the light color of the illumination light.

  Conventionally, desired illumination light is obtained by mixing a plurality of types of light having different emission colors. In addition, an illumination space is produced by changing the color of illumination light. For example, a variable color temperature illumination device has been proposed in which an operation amount of a variable resistor and a color temperature of light applied to an illumination space are associated in a proportional relationship (see Patent Document 1). This prior art lighting device corrects basic dimming data stored in a basic data table with correction dimming data stored in an auxiliary data table, and two types of lamps having different color temperatures of emitted colors. The color temperature of the mixed color light is changed in proportion to the operation amount of the variable resistor while keeping the total of the light beams emitted from the light.

Further, a plurality of light sources having different emission colors, a lighting circuit for dimming each light source, a setting unit for setting a desired color and brightness, and a dimming amount for each light source are determined based on the setting of the setting unit. There has been proposed a variable color illumination device that includes a light control amount determining means and includes a light source, a lighting circuit, and a light control amount determining means within a lamp body (see Patent Document 2). In this conventional variable color illumination device, a dimming signal of one lamp and color temperature information indicating the light color of illumination light are output from an operation unit as setting means. For this reason, the types of signals sent from the setting means to the lamp body can be reduced, the number of wirings can be reduced, and a special transmission signal such as a multiplex transmission system is not used, so that the configuration is not complicated. Is.

  The lighting signal, the extinguishing signal, or the variable color signal generated by the control unit 36 is input to the lighting control unit 37 of the lighting circuit unit 39. The lighting control unit 37 controls the main circuit unit 38 according to a lighting signal, a light-off signal, or a variable color signal.

  As shown in FIG. 6, the main circuit unit 38 includes a DC power supply circuit 42 and constant current circuits 43 to 46. The DC power supply circuit 42 is formed to rectify and smooth the AC voltage of the commercial AC power supply Vs and output a predetermined DC voltage. The constant current circuits 43, 44, 45, 46 are DC power supply circuits via the first light emitting unit 10, the second light emitting unit 11, the third light emitting unit 12, and the fourth light emitting unit 13 of the LED module 6, respectively. 42.

  In the constant current circuit 43, an NPN transistor Q 1 and a resistor R 1 are connected in series to the blue LED 16 of the first light emitting unit 10, and are connected between outputs of the DC power supply circuit 42. An NPN transistor Q2 is connected between the base of the transistor Q1 and both ends of the resistor R1, a series circuit of the resistor R2 and the DC voltage source Vref1 is further connected, and a diode D1, an operational amplifier OP1, and a DC voltage source Vref2 are connected in series. The circuit is connected. The DC voltage source Vref2 is connected to the non-inverting input terminal of the operational amplifier OP1. The inverting input terminal of the operational amplifier OP1 is connected to the output terminal. The diode D1 is connected such that the cathode side is the output terminal of the operational amplifier OP1 and the anode side is the base side of the transistor Q1. The base of the transistor Q2 is connected to the lighting control unit 37.

  The operational amplifier OP1 acts to extract the voltage applied to the base of the transistor Q1, and applies a constant voltage equivalent to the DC voltage of the DC voltage source Vref2 to the base of the transistor Q1. Thereby, when the transistor Q2 is turned off, the transistor Q1 is turned on, and the constant voltage is generated between both ends of the resistor R1. As a result, a direct current voltage obtained by subtracting the voltage across the resistor R1 from the direct current voltage output from the direct current power supply circuit 42 is applied across the blue LEDs 16 connected in series. As shown in FIG. Current AR flows. When the transistor Q2 is turned on, the transistor Q1 is turned off and no current flows through the blue LED 16. Thus, the transistor Q2 (transistor Q1) is turned on and off, and the on-time and off-time within a predetermined time are adjusted, whereby the average current flowing through the blue LED 16 is adjusted. When the constant current AR flows through the blue LED 16, yellow light is emitted from the first light emitting unit 10.

  The constant current circuits 44, 45, and 46 are configured in the same manner as the constant current circuit 43, and the respective transistors Q2 are controlled to be turned on and off. As shown in FIG. It is adjusted for. Then, when a constant current AR flows through each blue LED 18, blue LED 20, and red LED 22, green light is emitted from the second light emitting unit 11, blue light is emitted from the third light emitting unit 12, and the fourth Red light is emitted from the light emitting unit 13.

  The lighting control unit 37 is formed with a microcomputer or the like. When a lighting signal is input from the control unit 36, a high signal and a low signal are alternately supplied to the bases of the transistors Q2 of the constant current circuits 43 to 46 to turn on and off the transistor Q2. Thereby, yellow light, green light, blue light, and red light are each radiated | emitted from the 1st-4th light emission parts 10-13 of the LED module 6, and the illumination light which mixed those each color light is obtained. Here, the control unit 36 may generate the lighting signal so as to control the color mixing ratio of each color light immediately before the LED module 6 is turned off, or control the lighting signal to a preset color mixing ratio of each color light. It may be generated.

  Moreover, the lighting control part 37 will supply a high signal continuously to the base of each transistor Q2 of the constant current circuits 43-46, if the light extinction signal is input from the control part 36. FIG. Accordingly, the transistor Q2 is turned on, the transistor Q1 is turned off, and the first to fourth light emitting units 10 to 13 do not emit light. That is, the LED module 6 as the light source is turned off.

  Then, when the variable color signal is input from the control unit 36, the lighting control unit 37 adjusts the on time and the off time of each transistor Q <b> 2 of the constant current circuits 43 to 46, and mixes each color light emitted from the LED module 6. The ratio is set to a color mixing ratio of each color light according to the variable color signal. The association between the color mixture ratio of each color light and the on time and off time of each transistor Q2 of the constant current circuits 43 to 46 is stored in advance in an internal storage unit (not shown) or is processed by a microcomputer. ing.

  FIG. 8 shows a range of light colors that can be controlled by the lighting control unit 37. That is, in the figure, point A indicates the chromaticity when only the first light emitting unit 10 (yellow light) is turned on and the second to fourth light emitting units 11 to 13 are turned off. Similarly, for point B, only the second light emitting unit 11 (green light) is lit all light, and for point C, only the third light emitting unit 12 (blue light) is lit all light, and D point is 4 shows the chromaticity when only the four light emitting sections 13 (red light) are turned on and the remaining light emitting sections are turned off.

  Each color light emitted from the LED module 6 can be varied within a range of points A to D in the figure. In the range, for example, the color mixing ratio of each color light is set in advance so that the chromaticity change indicated by the curves E1 and E2 is obtained. That is, for a receiving operation exceeding a predetermined period (1 second) in the communication unit 30 of the main operation panel device 4 or a pressing operation exceeding a predetermined period of the switch unit 8 of the wall switch device 3, for example, f1 in the curves E1 and E2 , F2, f3, f4, and f1, the light color of each color light (illumination light) emitted from the LED module 6 is changed.

  The color mixing ratio of each color light emitted from the LED module 6 with respect to the preset variable color control signal (reception period exceeding a predetermined period) as shown by the curves E1 and E2 is stored in the storage unit 40. It is. The storage unit 40 stores the color mixture ratio of each color light when the LED module 6 is controlled to be lit. As a result, when the switch unit 8 of the wall switch device 3 is pressed again for a predetermined period of time, the control unit 36 can change based on the curves E1 and E2 from the color mixture ratio of each color light when the pressing operation is performed. A color signal can be generated. Further, when the LED module 6 is turned on again, it is possible to generate a lighting signal for controlling the LED module 6 with the color mixture ratio of each color light immediately before the LED module 6 is turned off.

  The control terminal device 4 may be one in which the lighting circuit unit 39 is formed as a separate lighting device.

  Next, the operation of the embodiment of the present invention will be described.

  When the switch unit 8 of the wall switch device 3 is pressed, an operation signal is output from the wall switch device 3 to the transmission line 7, and this operation signal is received by the communication unit 30 of the main operation panel device 4. When the operation signal is received within a predetermined period (for example, 1 second) or less by the communication unit 30, the main control unit 31 of the main operation panel device 4 generates a lighting control signal or a light-off control signal as an illumination control signal and performs communication. The signal is output from the unit 30 to the transmission line 7. The lighting control signal or the extinguishing control signal is received by the receiving unit 35 of the control terminal device 5.

  The control unit 36 of the control terminal device 5 generates a lighting signal or a light extinction signal that can control the lighting or extinguishing of the LED module 6 according to the lighting control signal or the light extinction control signal. Here, the lighting signal is generated so that, in addition to the lighting control, the color mixing ratio of each color light immediately before the LED module 6 is turned off can be controlled. The lighting circuit unit 39 lights (emits light) the first to fourth light emitting units 10 to 13 of the LED module 6 at a color mixture ratio of each color light immediately before the light is turned off in accordance with the lighting signal. Moreover, the lighting circuit unit 39 turns off the LED module 6 in response to the turn-off signal. Thus, the LED module 6 can be turned on or off by a pressing operation of the switch unit 8 of the wall switch device 3 within a predetermined period (1 second).

  Further, the main control unit 31 of the main operation panel device 4 receives reception information indicating that the operation signal is received exceeding the predetermined period when the operation signal is received exceeding the predetermined period (1 second). A variable color control signal as an illumination control signal is generated and output from the communication unit 30 to the transmission line 7.

  The variable color control signal is received by the receiving unit 35 of the control terminal device 5. The control unit 36 receives the reception period of the reception information of the variable color control signal from the color mixture ratio of each color light emitted from the LED module 6 with respect to the variable color control signal (reception period exceeding a predetermined period) stored in the storage unit 40. The color mixing ratio of each color light with respect to is obtained, and a variable color signal for controlling each color light emitted from the LED module 6 to the obtained color mixing ratio of each color light is generated. Here, the control unit 36 determines the LED module 6 when the reception unit 35 starts to receive the variable color control signal with respect to the variable color control signal (a reception period exceeding a predetermined period) stored in the storage unit 40. A reception period that is a color mixture ratio of each color light being controlled is obtained, and a reception period of the reception information of the variable color control signal is started from this reception period, and the color mixture of each color light with respect to the reception period of the reception information of the variable color control signal The ratio is calculated. As a result, a variable color signal for controlling the color mixture ratio of each color light emitted from the LED module 6 based on the curves E1 and E2 shown in FIG. 8 is generated with respect to the reception information of the variable color control signal.

  The lighting circuit unit 39 controls the color mixture ratio of each color light emitted from the LED module 6 according to the variable color signal. When the pressing operation of the switch unit 8 of the wall switch device 3 continues, the variable color control signal is continuously output from the main operation panel device 4, and the variable color control signal is output from the control unit 36 of the control terminal device 5. A variable color signal corresponding to the signal is generated. Thereby, the color mixture ratio of each color light emitted from the LED module 6 gradually changes based on the chromaticity paths f1 to f4 of the curves E1 and E2 shown in FIG. Thus, the color mixture ratio of each color light radiated | emitted from the LED module 6 can be changed gradually by pressing operation exceeding the predetermined period (1 second) of the switch part 8 of the wall switch apparatus 3. FIG.

  As described above, the LED module 6 is turned on or off as usual by pressing the switch unit 8 of the wall switch device 3 that turns on and off the LED module 6 as a light source within a predetermined period (1 second). . Further, by continuously pressing the switch unit 8 of the wall switch device 3 over a predetermined period, each color light emitted from the LED module 6 gradually changes at a preset color mixture ratio. Therefore, the light color of the illumination light emitted from the lighting fixture 2 can be varied using the conventional wall switch device 3 without using a dedicated operation device, and the illumination light can be produced. .

  The main control unit 31 of the main operation panel device 4 receives the operation signal when the operation signal output from the wall switch device 3 is received over a predetermined period (1 second) in the communication unit 30. When the process is completed, the variable color control signal may be output to the transmission line 7. And the control part 36 of the control terminal device 5 judges that the variable color control signal is continuously output from the communication part 30 over the reception period exceeding the predetermined period of the operation signal of the communication part 30, and LED You may form so that the variable color signal which changes the color mixture ratio of each color light radiated | emitted from the module 6 gradually may be produced | generated.

  The main control unit 31 of the main operation panel device 4 transmits the variable color control signal to the transmission line when the communication unit 30 receives the operation signal output from the wall switch device 3 over a predetermined period and when the reception is completed. 7, the variable color control signal can be easily generated, and the transmission amount transmitted (output) to the transmission line 7 can be reduced. Further, the control terminal device 5 determines that the variable color control signal is continuously output from the communication unit 30 over the reception period exceeding the predetermined period of the operation signal of the communication unit 30 and controls the LED module 6. Therefore, the color mixing ratio of each color light emitted from the LED module 6 can be quickly and gradually changed with respect to the pressing operation of the switch unit 8 of the wall switch device 3, and the illumination light emitted from the lighting fixture 2 can be changed. The light color can be changed quickly.

  The main operation panel device 4 stores the color mixing ratio of each color light of the LED module 6 corresponding to the reception period of the operation signal output from the wall switch device 3 by the storage unit 32, and the main control unit 31 stores the operation signal When the reception period exceeds the predetermined period (1 second), the variable color control signal is generated based on the color mixture ratio of each color light of the LED module 6 corresponding to the operation signal reception period stored in the storage unit 32. You may comprise as follows. Then, the control terminal device 5 generates a variable color signal for controlling the LED module 6 so that the control unit 36 changes the color mixture ratio of each color light of the LED module 6 according to the color mixture ratio of the variable color control signal. You may comprise.
