Audi A4 headlamps featuring Seoul Semiconductor WICOP bi-colour LEDs
Seoul Semiconductor Co., Ltd, a leading global innovator of LED products and technology, announced that it has supplied WICOP Bi-colour (2 colours in one package) LED products for the daytime running lights and front turn signals of the 2020 Audi A4 (B9 facelift) headlamp.
This is the first example of Seoul Semiconductor’s WICOP product being mounted on an Audi headlamp. WICOP Bi-colour LED is a core patented technology of Seoul Semiconductor that realizes both white and yellow in one package. It is designed to directly mount the LED chip on the board without an additional package.
“Due to the narrow space between the light emitting surfaces of the Bi-colour LED, it is technically beneficial to light up one cavity with yellow for turn and white for DRL. This advantage opens up the possibility of slimmer headlamp designs,” said Dr. Michael Hamm, the head of development headlamps of Audi.
In the meantime, Seoul Semiconductor has already developed the more compact WICOP Gen2 mini Bi-colour emitter while including the advantages of the existing WICOP in combination with even slimmer footprint.
“The [WICOP Gen2] family has been developed as a light source suitable for automobile main functions, daytime running lights and turn indicators. Actually, we are developing [WICOP UHL (Ultra High Luminance)] with excellent high luminance and heat dissipation performance for the next generation of slim headlamps. Accordingly, European headlamp customer inquiries for our innovative products have increased and we have been engaged with customers in more than 20 headlamp projects for next generation cars,” said In Heum Park, vice president of automotive division of Seoul Semiconductor.
WICOP technology is widely applied not only to vehicle lighting, but also to high-brightness TVs and LCD backlights for mobile phones, flash for smartphone cameras, and high-power general lighting, as it has excellent thermal conductivity and is easy to configure light, thin and compact lenses.
