The pcb board of driving is physically separated, is electrically connected LED light source and LED drivings only with wire harness, LED light source is made in principle
This thermal source is driven to ensure that LED reaches less light decay away from LED.The LED drivings of this design method can use
Resistance-type, linear constant current formula or DCDC formulas, because light decay is no longer closely related with the form of LED drivings, but this system is set
Meter needs larger space to be respectively arranged LED light due to LED light source and LED driving physical separations in the whole modulated structure of light fixture
Source wiring board and LED drive control plates, there is certain demand to the space inside lamp chamber.In face of the more doing the more thin, more do it is smaller after
Lamp shape-designing, the system design scheme of this Rear Fog Lamp has been increasingly difficult to meet lamp body shape-designing, while also is difficult to accomplish
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.
