PROBLEM TO BE SOLVED: To reduce a wiring amount as far as possible when constituting a unit for performing driving control over a plurality of loads with a controller.SOLUTION: Three LED chips of RGB being light sources 33a to 33d of reading lamps 25 to 31 and a controller built-in connector 35 are mounted on the same circuit board 37 to eliminate connection between a controller 35a of the controller built-in connector 35 and the respective light sources 33a to 33d by a signal line. Moreover, the controller 35b and an illumination ECU 43 are connected with a multiplex communication line 39, and the multiplex communication line 39 is wired to the inside of a pillar of a vehicle 1. Accordingly, the number of wires is reduced compared with a case that individual wires connected to the respective light sources 33a to 33d respectively are electrically wired into the pillar, and a limited space in the pillar in which many other wires are electrically wired can effectively be used. |
