Abstract

The invention provides a PCB layout system suitable for an automotive LED lamp. The PCB layout system comprises an LED light source module and an LED driving module, wherein the LED light source module is arranged in the central area of the PCB; and the LED driving module is used for driving the LED light source module, and comprises a plurality of electronic components which are arranged in a first area and a second area which are separated by the central area. According to the system, the technical problem that an LED driving circuit and an LED light source of a traditional vehicle signal lamp are separately arranged on two different PCBs and a connecting line needs to be arranged between the two PCBs is solved, so that the wiring harness is saved, and the loop area from the LED light source to the LED driving circuit is reduced, thereby optimizing the EMC electromagnetic interference problem; and through precise and excellent PCB layout, the LED signal lamp module has excellent EMCelectromagnetic compatibility performance.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a PCB board layout system PCB suitable for automotive LED lamps. Background technique [0002] LED signal lights can play a signaling role in the driving process and play a key role in driving safety. With the development of science and technology, there are more and more electronic devices in automobiles. With the increase of electronic devices, it also brings complex electromagnetic compatibility problems. How to design the electronic circuit and PCB layout of the standard LED signal light module plays a key role in the electromagnetic compatibility of the LED signal light module. [0003] At present, in the automotive lighting industry, the LED light source and the LED driver module are usually separated independently, and the two are connected through a wiring harness. The wiring harness is easy to introduce or emit electromagnetic interference, which is not conducive to the r...
