The continuous penetration of LED automotive headlights in automotive exterior lighting applications is increasingly replacing traditional lighting solutions, requiring a more efficient, robust, and cost-effective electronic device and driver IC to make LEDs superior in such applications. Get the most out of it. This important component of the LED lighting system points to the factors that need to be considered when developing the LED external light drive electronics architecture. LED car headlights are suitable for a variety of lighting applications in automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signals, daytime running lights, pedal lights, instrument lights, License plate lights, door lights, interior lights, width lights, navigation, entertainment systems, backlights and lights. These features include LED thermal management, flexible drive of different LED configurations, and cost-effective system design. Light-emitting diodes (LEDs) have been used in the automotive industry for more than 15 years. In the past, the available color and power levels limited LED applications to instrument panel, interior lighting, and some low-power taillight hybrid lighting functions.
LED car headlights are increasingly used in these automotive front lighting applications, mainly because of their unique advantages in style and design compared to conventional incandescent or high-intensity discharge (HID) lamps. It is also due to the low power consumption feature. However, it is equally important that with the continuous development of LED technology, higher power levels and wider color gamuts can be provided. At present, in automotive front lighting applications, LED car headlights have the same performance as incandescent lamps
