Lumileds’ LED lumen maintenance exceeds DLC Premium testing specs in four main product families
LED maker Lumileds of San Jose, CA, USA says that it is the only company to meet the Premium specifications of the DesignLights Consortium (DLC) in four main product families. LUXEON LEDs, within the high-power, color, chip-on-board (CoB) and mid-power families, exceed DLC Premium specifications even at high operating temperatures and drive current conditions.
“Whether your application calls for a high-power, mid-power, chip-scale package (CSP), CoB or color LED, LUXEON LEDs can be used to specify and design a light engine that meets the top-tier specifications of DLC Premium and be assured of the very best lumen maintenance performance,” says Shih Shun Mark Chang, global director, Technical Solutions Management at Lumileds.
Lumileds claims that it pioneered the standardization of lumen maintenance testing in 2008 and was the first company to provide LM-80 test report data to customers. Since then, it has improved its manufacturing and testing processes, from epitaxy to new phosphor development to die fabrication and in-situ process control. With over 3 billion device-hours of testing, Lumileds product portfolio includes 23 unique products with data from hundreds of millions of LM-80 device hours proving that LUXEON products far exceed the DLC’s Premium targets for efficiency and lumen maintenance — including L90 times surpassing the DLC Premium requirements of 36,000 hours, with many products demonstrating L90 times in excess of over 100,000 hours.
