Abstract
A vehicle lighting unit can not only promote the dissipation of heat from a semiconductor light emitting device and a drive circuit for the device, both of which are the heat generation members, but also improve its maintenance workability. The vehicle lighting unit can include a light source module having a module main body. The module main body can include first and second semiconductor light emitting devices, drive circuits configured to drive and control the first and second semiconductor light emitting devices, and a heat dissipation fin for dissipating heat generated by the semiconductor light emitting devices and the drive circuits. Both the semiconductor light emitting devices and the drive circuit are directly attached to the module main body.
