Standardization, a Rear Fog Lamp electronic control system is set to be applied to the lamp body structure of all vehicle back lights.
Conventional Rear Fog Lamp LED electronic control system design methods also have：LED light source and LED drivings are together placed on
On same pcb board, LED drivings use simple resistance-type or linear constant current mode, due to resistance only several or linear constant current
Chip only one, the circuit of LED drive parts will not take excessive space, thus this scheme still can substantially meet it is small-sized
Change design, but due to the influence to LED of efficiency and caused heat of its LED drivings, prevent the light decay of optical system from reaching
To Expected Results.
