Everlight introduces Shuen LED series with slim package, high power, high luminosity

Press release, September 29; Yvonne Yu, DIGITIMES [Tuesday 29 September 2009]

Adding to an already broad and innovative portfolio of surface mount packaged high power LEDs, Everlight Electronics introduces the "Shuen" series - our most powerful and brightest LED series in a slim ceramic package.

The Shuen package is a surface-mount high-power device offering high brightness in a compact form factor, making it suitable for various lighting applications including general illumination as well as, flash, spot, signal, industrial and commercial lighting. The thermal pad of this device is electrically isolated providing for improved thermal and electrical characteristics. It is well known that the benefits of LED devices are their environmental friendliness, energy savings, reliability and long life. The Shuen series exhibits all these advantages while providing high efficiency luminous output. The life-time of the Shuen series as well as other LEDs is defined as the percentage of initial light output remaining after a specified period of time. Shuen colors of cool-white, neutral-white, warm-white, green, cyan, blue, and royal-blue colors average 65,000 hours for 70% lumen maintenance (B50 L70) under 350mA operating current. This projection is based on constant current operation with junction temperature maintenance at or below 135°C. Other Shuen series colors like red, orange, amber, and royal-red also average 65,000 hours for 70% lumen maintenance (B50 L70) under 350mA operating current, but this projection is based on constant current operation with junction temperature maintenance at or below 110°C.

Within the global solid-state lighting market, Everlight strives to conform to all environmental initiatives. The Shuen series meets the European Union directives on the restriction of hazardous substances in electronic equipment - namely the RoHS directive. All materials and processes of the Shuen series are free of form lead, mercury, cadmium, hexavalent, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE). Everlight is also promoting closer working relationships between our R&D and Sales and Marketing teams to better meet and exceed our customer's expectations from both product offering and technology perspectives. The Shuen LED series and its many technical features is a result of fostering a closer relationship between these teams.
