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.

A world first on the Audi Q9: digital OLED panel with a curved design

The new Audi Q9 introduces the automotive industry's first three-dimensionally curved digital OLED panel, enabled by ultra-thin carrier glass (0.1 mm) that allows a bend radius up to 200 mm. Third-generation digital OLED technology comprises 512 segments across six panels, including Audi’s largest OLED panel to date with 99 segments, enabling enhanced lateral visibility, new safety and communication functions, and personalized light signatures (static, active, semi-active) with 3D effects. Combined with digital Matrix LED headlights using micro-LED modules, the system enhances interaction with other road users and advances Audi’s decade-long OLED development.

Expanding the horizons of car body lighting – Expert Talk by Dr. Thorsten Anger, Lumileds

Recording of an LpS DIGITAL expert talk, published on 29 November 2024 (34 minutes). Dr. Thorsten Anger, Product Manager 3D LED & MxN at Lumileds, explains why car body lighting – light guides, backlit surfaces and three-dimensional lit structures – is still largely bespoke and too costly for mainstream vehicles, and presents Lumileds’ modular answers: the LUXEON Versat 2016 LED family with new UltraBlue and Warm White options, dynamic signature lights with 192 individually addressable pixels, the LUXEON 3D LED series in three performance tiers, and a coin concept with 49 % optical efficiency.
