The development prospects and applications of LED car lights

LED car lights refer to the use of LED technology inside and outside the car for external and internal lighting. External lighting equipment involves thermal limits and EMC issues, as well as many complex standards for unloading load testing. LED car lights can be widely used in LED car lights to create the environment in the car, with a life span of 50,000 hours, the structure of the LED is solid, not easily affected by vibration, and the light output brightness will not significantly decrease during use. LED car lights are suitable for various lighting applications of automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signal lights, daytime running lights, pedal lights, instrument lights, license plates Lights, door lights, interior lights, width indicator lights, navigation, entertainment systems, backlights and indicator lights, etc.

There is no doubt that the use of high-brightness LED lighting will become the main feature of future cars, thanks to the many basic advantages that LEDs have over traditional incandescent lighting solutions. In addition, the use of LED lighting can also drive changes in automotive design technology and design style. However, just like any innovative technology, LEDs still need to overcome many difficulties before they are widely used in automotive lighting.

In automotive applications, LEDs are mainly used for exterior and interior lighting. External lighting equipment involves thermal limits and EMC issues, as well as many complex standards for unloading load testing. For example, whether the voltage is 40V, 60V, 80V, or 100V LED drive circuits must meet the strict requirements of automotive EMC specifications. For LEDs driven by high-efficiency, inductive switching regulators, it is difficult to meet the above requirements, and all preventive measures will increase the cost of the overall solution. In the field of exterior lighting applications, headlights, fog lights and indicator lights are the target applications.

Due to the advantages of LEDs, LEDs can be widely used to create a comfortable environment in the car, such as instrument lighting, pedal lighting, aeronautical chart lights, rear fog lights, car rear brakes and indicator lights, and used to display the car’s entertainment The mixed-color backlight and atmosphere lighting of the flat-panel display of “Information” will further increase the application of LEDs.
