The intelligent driving circuit for the LED vehicle lamp solves the problems of low intelligence and high cost of an existing automotive LED lamp driving technology.

Description

technical field [0001] The invention belongs to the technical field of LED driving, and in particular relates to an intelligent driving circuit for LED vehicle lights. Background technique [0002] LED is a current-controlled semiconductor device. In order to ensure the consistency of its brightness, a constant current source drive circuit is usually used. For automotive LED lamps, to reliably drive LED strings with constant current, the drive controller must have precise voltage and current regulation, protection circuits, and dimming functions. Therefore, it is very necessary to design a driving circuit with good voltage regulation performance and constant current output. [0003] With the maturity of automotive LED lamp driving technology, the types of drive control systems are also increasing. Automotive LED lamps require that the drive control system can achieve stable output and high efficiency, so as to ensure that the drive control system has a competitive advantage...
