Sulfur-resistant golden frame automotive LED extends color stability

April 07, 2015 // By Paul Buckley
Everlight Electronics Co., Ltd., has introduced the company's most highly efficient/sulfur resistant ‘golden’ Series which is developed to perform even in severe environments and satisfy all the demands posed by automotive applications.

Following the trend of high-tech design in automotive applications, Everlight recognises LEDs with stable performance and high quality are capable of to fulfilling customers’ expectations. The golden automotive series exactly matches the highest requirements. A golden frame improves product ability to resist sulfur. No matter how severe or bad the environment is the light will continue to operate. The golden series is used in head lamps, DRL, fog lamps, side signal lamps and rear tail lamps; over 0.5 W products is suitable for side Signal Lamp (A09K, 67-21 and 67-31). The new versions enhanced with a golden lead frame include the A09KU, 67-21U and 67-31U. Their original counterparts with silver lead frame remain in the portfolio and continue to be offered.

The advantage of PC Amber is an enhanced brightness at high temperatures. The device's three chip manufacturing process in contrast to the four chip process for traditional amber LEDs results in a brightness decay at 85°C of 15% versus 30-50% for the original amber LEDs. As a result the PC Amber LEDs provide a superior thermal and color stability performance. All of Everlight’s automotive LEDs with wattages of 0.5 W or more are PC Amber-colored now.

Samples are available on request and the device is now in volume production
