Significant Improvement of the Thermal Efficiency of Headlamps for Vehicles

Seoul Semiconductor announced that it launches WICOP TE (Top Electrode) designed to significantly improve the thermal efficiency of headlamps for vehicles. WICOP LED was applied to 10% of the global vehicle production in 2020, and is expected to see an increasing demand in the future electric vehicle market. Seoul Semiconductor expects to accelerate the move to expand its market share in the global automotive lighting LED market worth approximately USD 2.7 billion.

Due to the growing demand for electric vehicles, the interest in high-efficiency LED products for a light headlamp and less batteries consumption is increasing. Accordingly, the thermal dissipation performance of the headlamp has become an important task in order to improve the efficiency and lifetime against the temperature increase.

Seoul Semiconductor’s WICOP TE for headlamps has deviated from the previous method of attaching the LED package to the printed circuit board (PCB) and can attach the package directly on the heatsink, designed to quickly discharge the heat generated in the headlamp.

The WICOP is the second generation technology of the LED industry and Seoul Semiconductor obtained a permanent injunction against 13 automotive lighting brand LED products infringing WICOP patents in 2021 July. Seoul Semiconductor will introduce this new ‘WICOP TE’ products, the natural sunlight spectrum LED ‘SunLike’ with the luxurious interior colors and beneficial effects on learning and good sleep, and UV LED ‘Violeds’ for disinfection in the automotive air conditioning systems at the DVN workshop in the U.S. on September 21, 2021.

“Weight reduction and heat dissipation performance of headlamps are more important due to increased demand for electric vehicles and slim headlamp design trends. Seoul Semiconductor has already applied high-efficiency and high-heat dissipation WICOP products to more than 100 global vehicle brands, and we expect to increase automotive LED sales through continuous demand expansion in the future,” said an official of Seoul Semiconductor.

Seoul Semiconductor has continued research and development in compound semiconductors for over 30 years, which has a product portfolio with all wavelengths (200nm to 1,600nm) ranging from ultra violet to visible ray and infrared ray (IR, VCSEL). Based on 14,000 patents, it is leading the LED technology in the global market.
