LED modules focus on harsh automotive environments

June 03, 2014 // By Paul Buckley
Everlight Electronics Co., Ltd., has introduced a high-performance series of LED modules for automotive headlight applications.

The Argus Series claims to meet the demands and technical criteria of the highest quality in the market particularly for the high temperature and harsh environment in the headlight assemblies.

Low thermal resistance and high heat dissipation rate with outstanding cost/performance ratio Everlight’s high-power Argus series of LED headlight modules feature low thermal resistance and a high heat dissipation rate. The overall package size is reduced to allow flexible space for the component manufacturers to design their headlight products. During the car LED design stage, Everlight works with several leading car lighting manufacturers for the demands and
concepts of car LED products in the product design. From heat dissipation to optical design, Everlight has developed double-chip, 4-chip, 5-chip and
6-chip designs based on top-notch cooperation of optical and heat dissipating technologies.

The Argus Series is a line of high-performance headlight LED modules based on ceramic substrates featuring high heat dissipation rate up to 170 W/mK, far better than those provided by conventional ceramic substrates. A single chip running at 1 A provides up to 1200 lm. With a properly designed heat dissipating mechanism, a single chip provides highly stable performance even at 1.2 A. The single-chip Tj design that has passed the 150°C high-temperature test is perfect for the harsh, extremely hot environment in a headlight assembly. For the optical element technology, Everlight was able to control the multi-chip intervals within 0.08 mm thanks to meticulous manufacturing process and innovated technology, allowing much simpler optical design and highly refined cut-off lines.

The quality of Everlight’s car LED components is certified for TS16949, and the LEDs themselves are AEC_Q101 certified.
