LED driving circuit and its application in automotive light source design: LED is a new type of semiconductor light source with the advantages of low energy consumption, long life and short response time. The LED light source driving circuit is complex, which limits the application of LED in the industrial field. Starting from the development and characteristics of LED, combined with the constant current light-emitting characteristics of LED and considering the low power supply voltage in industrial products, the LED driving circuit is designed. Through experimental analysis and optimization, the energy consumption of the light source is reduced while ensuring the brightness of the light source, and it is applied to the design of automotive light sources. Keywords: LED; driving circuit; automobile
