  Further, by applying the technique used in the illumination device shown in FIG. 3 to the illumination device using the light source composed of the above-described LED, the light from the illumination device can be transmitted only by the series of switch operations on the power switch SW1 ′. In order to be able to change the illumination scene by changing the color temperature, it is necessary to provide a plurality of types of the light sources having different color temperatures to correspond to each illumination scene. In particular, in order to be able to finely set the color temperature of the light source, it is necessary to provide various types of the light sources having different color temperatures, which may increase the size of the lighting device.

  The present invention has been made in view of the above-mentioned reasons, and has an object of providing a lighting device that includes a plurality of types of light sources having different colors, can easily dim each type of light source, and can be downsized. Is to provide.

  The invention of claim 1 includes a plurality of types of light sources having different colors, a plurality of output adjusting means for adjusting the light output of each type of light source, and an output adjusting means corresponding to the light source for adjusting the light output. A dimming unit capable of selectively dimming the light source by controlling, and a power switch provided on a power supply path to the light source, and the power source when each type of light source is lit When a series of switch operations for continuously performing an on operation, an off operation, and an on operation for a switch within a predetermined time or less is performed, the dimming unit controls all the output adjusting units to control the plurality of types of light sources.

Therefore, it is possible to easily dim each type of light source as compared to a conventional lighting device having a plurality of types of light sources including a remote controller and an LED light controller. In addition, since the plurality of types of light sources can be dimmed only by the series of switch operations, it is not necessary to use a remote controller, so that the remote controller can be lost and the plurality of types of light sources can be dimmed.

If the light output is appropriately adjusted, the desired color temperature can be set, so that variations in the illumination scene can be increased.

  According to the first aspect of the present invention, since a plurality of types of light sources having different colors can be dimmed only by a switch operation on the power switch, a plurality of types of light sources having a conventional remote controller and LED light controller are provided. Compared to the lighting device, each type of light source can be easily dimmed. In addition, by changing the light output of each of the plurality of types of light sources separately by only a series of switch operations, a plurality of illumination scenes can be realized by combining a plurality of types of light sources having different light outputs. Since it is not necessary to provide a plurality of light sources having different color temperatures corresponding to each scene, the number of light sources necessary for realizing a plurality of illumination scenes can be reduced, and the lighting device can be reduced in size.

And a light control means 7 for adjusting the light ratio. That is, the illuminating device of the embodiment includes three types of first light source 11 to third light source 13 of a red light source, a green light source, and a blue light source.

  Here, the power supply circuit 21 may include a diode bridge (not shown) for rectifying the output of the AC power supply AC and a chopper circuit (not shown). In the lighting device of the embodiment, the power switch SW1 is interposed between the AC power source AC and the power circuit 21, and the lighting device is turned on and turned off by turning on the power switch SW1. As a result, the power to the lighting device is shut off.

  In addition, the lighting device detects on / off of the power switch SW1, turns on the power by turning on the power switch SW1, and then turns off the power switch SW1 and turns on the power switch SW1 again. A timer circuit 9 that counts the time until the power is turned on (hereinafter referred to as determination time) is provided. The timer circuit 9 transmits a detection signal to the light control means 7 if the determination time is equal to or less than a predetermined time, and the light control means 7 adjusts the output of the first light source 11 to the third light source 13 as will be described later. I do. On the other hand, when the determination time is longer than the predetermined time (for example, 0.5 seconds to 2.0 seconds), the timer circuit 9 does not transmit a detection signal to the light control means 7 and turns on the lighting device. Or the power is cut off. That is, the timer circuit 9 compares the determination time with the predetermined time, so that the switch operation for the power switch SW1 is for turning on or off the power of the lighting device, or the first light source 11 To determine whether to adjust the output of the third light source 13.

  Here, the first output adjustment means 51 to the third output adjustment means 53 are a constant current circuit (not shown) and a switching element (not shown) connected in series to each of the first light source 11 to the third light source 13. A current adjusting circuit that is electrically connected to the constant current circuit and that analog-controls the magnitude of the direct current supplied from the constant current circuit to each of the first light source 11 to the third light source 13. (Not shown) and on / off timing of the switching element based on a dimming control signal, which will be described later, transmitted from the dimming means 7 to flow to the first light source 11 to the third light source 13 respectively. It comprises a duty control circuit (not shown) that adjusts the light quantity of the first light source 11 to the third light source 13 by controlling the duty ratio of the rectangular-wave direct current. The dimming unit 7 includes a receiving unit (not shown) for receiving the detection signal transmitted from the timer circuit 9 to each of the first output adjusting unit 51 to the third output adjusting unit 53, and When the receiving unit receives the detection signal, it generates a dimming control signal and transmits a dimming control signal to each of the first output adjusting unit 51 to the third output adjusting unit 53 (not shown). Z)). Moreover, the light control means 7 is provided with the memory | storage part (not shown) for memorize | storing the information regarding the light control ratio of the 1st light source 11 thru | or the 3rd light source 13, and based on the information regarding the said light control ratio. To generate the dimming control signal. In the lighting device of the embodiment, the first output adjustment unit 51 to the third output adjustment unit 53 do not include the constant current circuit and the current adjustment circuit, and include only the switching element and the duty control circuit. It is good also as a structure.

  Next, a procedure for adjusting the dimming ratio of the first light source 11 to the third light source 13 of the illumination device of the embodiment will be described with reference to FIG.

  In a state where the first light source 11 to the third light source 13 are turned off, a series of operations including an on operation, an off operation, and an on operation with respect to the power switch SW1 within a predetermined time (hereinafter referred to as a series of switch operations). (S1), the dimming unit 7 controls the first output adjusting unit 51 to the third output adjusting unit 53 and immediately before the first light source 11 to the third light source 13 are turned off. The first light source 11 to the third light source 13 are turned on at a dimming ratio at which the color temperature becomes (S2). Here, information relating to the dimming ratio is stored in the storage unit included in the dimming unit 7, and the dimming unit 7 performs the dimming ratio from the storage unit when the series of switch operations is performed. Information about the dimming ratio is acquired, and the first output adjustment unit 51 to the third output adjustment unit 53 are controlled based on the information about the dimming ratio, and the previous first light source 11 to third light source 13 are turned off. The first light source 11 to the third light source 13 are turned on so as to obtain the light control ratio immediately before.

  Next, when the series of switch operations are performed on the power switch SW1 (S3), the dimming unit 7 controls the first output adjusting unit 51 to the third output adjusting unit 53 in the lighting device. The one light source 11 to the third light source 13 has the maximum color temperature within the range of the color temperature of the mixed color light so that the light output of each of the first light source 11 to the third light source 13 does not exceed the rating. The lighting device is in the full lighting mode (S4).

  Next, when the series of switch operations are performed on the power switch SW1 (S5), the dimming unit 7 causes the first light source 11 to the third light source 13 to be changed from the first light source 11 to the third light source 13 respectively. Within the range of color temperatures where the respective light outputs do not exceed the ratings, the maximum color temperature is continuously decreased and the light is turned off repeatedly to enter the first dimming setting mode (S6). That is, in the first dimming setting mode, when the first light source 11 to the third light source 13 are turned off at the maximum color temperature, the color temperature of the mixed color light continuously decreases. Again, the first light source 11 to the third light source 13 are lit at the maximum color temperature. Thereafter, as long as the series of switch operations are not performed on the power switch SW1, the dimming unit 7 changes the color from the state in which the first light source 11 to the third light source 13 are lit at the maximum color temperature. The first output adjustment means 51 to the third output adjustment means 53 are controlled so that the operation of turning off the lights with the temperature continuously decreasing is repeated.

  In the first dimming setting mode (S6), when the series of switch operations are performed on the power switch SW1 (S7), the dimming unit 7 causes the first output adjusting unit 51 to the third output adjusting unit. 53, the light output of the first light source 11 to the third light source 13 becomes constant at the light output at the color temperature of the mixed color light when the series of switch operations are performed on the power switch SW1. Thus, the light output fixing mode is fixed (S8).

  Next, when the series of switch operations are performed on the power switch SW1 (S9), the dimming unit 7 controls the first output adjustment unit 51 corresponding to the first light source 11 to control the first light source. 11 is a second dimming setting mode in which the light output is continuously decreased from the fully lit state to repeatedly turn off the light (S10). In other words, in the second dimming setting mode, when the light output continuously decreases from the state in which the first light source 11 is fully lit and is extinguished, the first light source 11 is fully lit again. Thereafter, as long as the series of switch operations are not performed on the power switch SW1, the dimming unit 7 repeats that the light output continuously decreases from the state in which the first light source 11 is fully turned on and is turned off. Thus, the first output adjusting means 51 is controlled.

  When the series of switch operations are performed on the power switch SW1 in the second dimming setting mode (S10) (S11), the dimming means 7 is the first output adjusting means corresponding to the first light source 11. 51, the light output is fixed so that the light output of the first light source 11 is fixed at the light output when the series of switch operations are performed on the power switch SW1 (S12). .

  Next, when the series of switch operations are performed on the power switch SW1 (S13), the dimming unit 7 controls the second output adjusting unit 52 corresponding to the second light source 12 to control the second light source. The second dimming setting mode in which the light output is continuously reduced from 12 to 12 and the light output is continuously turned off is repeated (S14).

  When the series of switch operations are performed on the power switch SW1 in the second dimming setting mode (S14) (S15), the dimming means 7 is a second output adjusting means corresponding to the second light source 12. 52, the light output of the second light source 12 is controlled so as to be fixed at the light output when the series of switch operations are performed on the power switch SW1 (S16). .

  Next, when the series of switch operations are performed on the power switch SW1 (S17), the dimming unit 7 controls the third output adjusting unit 53 corresponding to the third light source 13 to control the third light source. The second dimming setting mode in which the light output is continuously reduced from 13 to 13 and repeatedly turned off is repeated (S18).

  When the series of switch operations are performed on the power switch SW1 in the second dimming setting mode (S18) (S19), the dimming means 7 is a third output adjusting means corresponding to the third light source 13. 53 is controlled so that the light output of the third light source 13 is fixed so as to be constant at the light output when the series of switch operations are performed on the power switch SW1 (S20). . Here, the light output adjustment of the first light source 11 to the third light source 13 is completed. Further, data relating to the dimming ratio of the first light source 11 to the third light source 13 when the light output adjustment is completed is stored in the storage unit included in the dimming means 7.

  In other words, in the lighting device of the embodiment, when the series of switch operations are performed on the power switch SW1, the dimming unit 7 causes the first output adjustment unit 51 to the third output adjustment unit 53 to perform the first operation. All of the light sources 11 to 13 are turned on so that the maximum color temperature is obtained within a color temperature range that does not exceed the rated light output of each of the first light source 11 to the third light source 13. When the lighting mode is entered and then the series of switch operations are performed on the power switch SW1, the first output adjustment means 51 corresponding to the first light source 11 is controlled to control the first light source 11 to the third light source 11. This is the first dimming setting mode for dimming the light source 13. In the first dimming setting mode, when the series of switch operations are performed on the power switch SW1, the dimming unit 7 ends the first dimming setting mode. Thereafter, when the series of switch operations are performed on the power switch SW1, the dimming means 7 is the first output adjusting means 51 corresponding to any one of the first light source 11 to the third light source 13. Through a second dimming setting mode in which one of the first to third output adjusting means 51 is controlled to dim any one of the first light source 11 to the third light source 13. When the series of switch operations are performed on the power switch SW1 in the light setting mode, the light control means 7 controls one of the first output adjustment means 51 to the third output adjustment means 51. This is a light output fixing mode in which the light outputs of the first light source 11 to the third light source 13 are fixed to a constant light output.

  In the lighting device of the embodiment, in the first dimming setting mode, the dimming unit 7 corresponds to the first output adjustment unit 51 to the third output adjustment corresponding to the first light source 11 to the third light source 13. By controlling the means 53, the first light source 11 to the third light source 13 are made to repeatedly reduce the light output from the lighted state so as to achieve the maximum color temperature and turn off the light. Here, when the series of switch operations are performed on the power switch SW1 in the first dimming setting mode, the dimming unit 7 outputs the light outputs of the first light source 11 to the third light source 13. Is a light output fixing mode in which the light is fixed so as to be constant. Further, in the second dimming setting mode, the dimming unit 7 is configured to output the first output adjusting unit 51 to the third output corresponding to any one of the first light source 11 to the third light source 13. One of the adjusting means 53 is controlled so that any one of the first light source 11 to the third light source 13 continuously turns off the light output from the fully lit state. Let it repeat. Here, in the second dimming setting mode, when the series of switch operations are performed on the power switch SW1, any one of the first light source 11 to the third light source 13 is fixed. The light output fixing mode is fixed with the light output.

  Thus, in the illumination device of the embodiment, the light output of each of the first light source 11 to the third light source 13 can be adjusted only by the series of switch operations, and therefore the first light source 11 to the third light source. 13 can be easily dimmed.

  Further, in the lighting device of the embodiment, the user changes the light output of each of the first light source 11 to the third light source 13 only by the series of switch operations, so that the first light sources 11 having different light outputs are changed. Since a large number of illumination scenes can be realized by combining the third to third light sources 13, it is not necessary to provide a plurality of types of light sources (not shown) having different color temperatures to correspond to each of the plurality of illumination scenes. Thus, the number of light sources necessary for realizing a large number of lighting scenes can be reduced, and the lighting device can be reduced in size.

  Further, in the lighting device of the embodiment, since it is not necessary for the user to use a remote controller (not shown), a failure peculiar to the lighting device including the remote controller, for example, the remote controller is lost, As the light source 11 to the third light source 13 cannot be dimmed or a function for dimming the first light source 11 to the third light source 13 is added to the remote controller. The controller itself can be prevented from increasing in size.

  In the lighting device of the embodiment, when the user performs the series of switch operations, the dimming unit 7 continuously decreases the light output of each of the first light source 11 to the third light source 13, and thereafter When the switch operation is performed when the color temperature or color changes to the desired color temperature, the light output of the first light source 11 to the third light source 13 is fixed, thereby fixing the first light source 11 to the third light source 13. Since the color temperature of the light source 13 is set, the color temperature can be set finely, so that it becomes easy to realize the color temperature desired by the user.

  Furthermore, the illuminating device of the embodiment includes the first light source 11 that is a red light source, the second light source 12 that is a green light source, and the third light source 13 that is a blue light source. Since the desired color temperature can be set by appropriately adjusting the light output of each of the third light sources 13, variations in the illumination scene can be increased.

  In the embodiment, the case where the first light source 11 to the third light source 13 are LEDs having different emission colors has been described. However, the present invention is not limited to this, and the first light source 11 is an arc tube that emits red light. A red light source comprising a discharge lamp comprising a green light source comprising a light emitting tube emitting green light as the second light source 12, and a blue light source comprising a discharge lamp comprising a light emitting tube emitting blue light as the third light source 13 In this case, the first output adjustment unit 51 to the third output adjustment unit 53 may be lighting circuits for lighting each light source.
