LED penetration in automotive lighting applications continue to rise

What is the cause of the current LED popular situation?

The popularity of LED in automotive lighting applications continues to rise, thanks to its long life and the flexibility to be used in car body styling and interior design.

Despite the fact that the cost of LED is higher than that of the traditional incandescent bulbs, the momentum has not been contained, and some may be surprised. So, what is the cause of the current LED popular situation? The answer is surprisingly simple; the front of all vehicles is the same as the face of a person, the beauty of the impact on the potential buyers is extremely profound.

LED penetration in automotive lighting applications continue to rise

No matter compared with xenon lamp or incandescent light bulbs for headlights, daytime running lights and turn signal lights in the LED lighting design flexibility are far better. This allows the front end of the car body designers to complete some previously impossible to achieve design. However, before the car itself is precisely the LED application in the automotive environment is difficult to achieve the goal. The main reason lies in the thermal design of LED and its associated driver circuit.

The essence of the traditional light bulb is a "heater", and work under high temperature, and the difference is that LED and its driver circuit needs to be integrated as a part of the radiator shell, so that the heat away from the LED. Obviously, the conversion efficiency of the LED driver and its associated power loss will have a significant impact on the thermal design of the LED housing used in the automotive headlight configuration. Due to the negative impact of the high temperature operating environment on the LED light output and working life, all of the above precautions are essential.
