Seoul Semi Brings Innovation to EV Headlamps
New WICOP LEDs reduce headlamp power consumption up to 20 percent with an improvement of heat dissipation performance up to 40 percent
LED firm Seoul Semiconductor has announced its next-generation WICOP UHL (Ultra High Luminance) Series LEDs, which reduce headlamp power consumption up to 20 percent for electric vehicles, with an improvement of heat dissipation performance up to 40 percent. The company will begin mass production in 2021 and with promotions to key customers.
Battery power consumption is one of the important requirements that determine the range of an electric vehicle, or the driving distance on a single charge. In order to reduce the power consumption, it is critical to reduce the overall weight of automobile parts.
The next-generation “WICOP UHL” Series LEDs exhibit up to 40 percent better heat dissipation performance than other products in the current LED market. By applying WICOP UHL to automobile headlamps, the weight of lamp heat sink structure can be reduced by 75 percent. The LED emitting area of the product is extremely small (approximately 0.5mm2), which enables a slim headlamp design. This new LED technology completely compensates for the disadvantages of heat dissipation, as the lighting emitting area is smaller, and thus it enables not only slim lamp design but also high performance.
WICOP (Wafer Integrated Chip on PCB), a fundamental technology of the new product, is the world’s first patented package-less LED technology developed by Seoul Semiconductor. Unlike flip chip technology that must be bonded in the semiconductor process, WICOP LEDs can be easily surface-mounted (SMT) in the general substrate bonding process. Mini LEDs also use the WICOP technology with a robust structure.
“This new product will be mass-produced from 2021 according to requests of global headlamp manufacturers. And it can be adopted for headlamps of all automobile brands and designs,” said a representative of Seoul Semiconductor.
Seoul will showcase the WICOP UHL Series products at the Shanghai International Auto Lamp Exhibition (ALE), scheduled for October 15 – 16 in Shanghai, China.
