Light-emitting diodes (LEDs) have become the preferred light source for automotive headlamps due to their excellent durability, fast response times, higher efficiency, and superior optical performance compared to traditional halogen bulbs. However, their high power output, compact design, and positioning within the headlamp assembly pose significant thermal management challenges. Prolonged operation leads to a rise in LED temperature, resulting in reduced light output—a phenomenon known as LED derating. This decrease in light output can compromise visibility, posing safety risks to drivers and road users. Additionally, the proximity of the headlamp to the vehicle's engine further elevates the surrounding temperature, worsening the LED derating.
