PROBLEM TO BE SOLVED: To provide a color lighting unit easy to mount to a lighting system and good in color lighting effect due to a color-mixing by providing a substrate, an RGB emission element group and an electric wiring means disposed on the substrate, constituted such that the RGB emission element group can be independently controllably connected to a power source in every color emission element. SOLUTION: In a substrate 1, a printing wiring as an electric wiring means is formed on a back surface and the substrate 1 is provided with an inserting hole for a general illumination lamp socket 14 at a center and has a disc shape in which a positioning hole for mounting a lamp socket 3 and a terminal- inserting hole are formed. As the printing wiring on the back surface of the substrate 1, input terminals against respective color emission elements R, G, B and a printing wiring land as a wiring to the respective color emission elements connected to the input terminals are formed around the terminal- inserting hole. RGB emission element group 2 is provided with red emission element R of four lamps, green emission element G of four lamps and blue emission element B of eight lamps and are annularly disposed in two rows. |
