More specifically, the light emitters T1 to T4 are color LEDs each including light emitting elements of red (R), green (G), and blue (B), configured to output light of a desired color, depending on the light emitting pattern of these three light emitting elements. For example, the yellow light can be outputted, with the light emitting pattern that the light emitting element of red (R) and the light emitting element of green (G) are turned on, and the light emitting element of blue (B) is turned off. The blue light can be outputted, with the light emitting pattern that only the light emitting element of blue (B) is turned on. The red light can be outputted, with the light emitting pattern that only the light emitting element of red (R) is turned on. The purple light can be outputted, with the light emitting pattern that the light emitting element of red (R) and the light emitting element of blue (B) are turned on, and the light emitting element of green (G) is turned off. Hereinafter, the light emitters T1 to T4 may be unspecifically referred to as light emitter T.
The controller 100 outputs the light emission control signal to the light emitters T1 to T4, through a first cable, a relay connector URC, a relay connector DRC, and a second cable.
