Abstract:
A lighting system has light-emitting diodes as light sources mounted on a circuit board, in which the light-emitting diodes include a red light-emitting diode, blue light-emitting diode and a green light-emitting diode, the light-emitting diodes are constituted of one single unit including one for each of the red, blue and green light-emitting diodes, and the one single unit is repeatedly arranged as plural pieces on the same circuit board, and each of the red, blue and green light-emitting diodes is individually connected electrically to emit a light.
