COB LED series offers color on demand options
Everlight’s high-power (36 V) XUAN COB series offers the dual benefit of high efficiency and easy assembly. Covering a wide wattage range at customers’ preference from 2-50 W the MCPCB device can achieve > 130 lm/W. Designed with high thermal conductive Mirror-Aluminum substrate, it can be easily attached to the heatsink by holder or screws. Another feature of the XUAN series is its wide driving operation range, ensuring a super high efficacy in the typical driving state. In an over-driven state, however, it can still deliver a high lumen output and, with proper heatsink, also remains stable to bring about an economic lighting design. Seven different designs on Everlight’s XUAN LED are currently available in 1313 and 1919 dimensions with color temperature options from warm to cool (2700-6500K) and CRI ratings of 82 (>80), 92 (>90) and > 97 Ra. Everlight’s XUAN LEDs are a best fit for LED single light source applications like spotlights and downlights.
Another option is color on demand. The Color Choice Series CHI COBs (9-29 W) are designed on a Ceramic PCB package and is based on two color temperatures 2700K and 5700K which, when thoroughly mixed, can take on every ANSI color temperature in this CCT range. All mixture points achieve >110 lm/W and a CRI > 80 (R9> 0).
Everlight’s Color Choice Series directly targets indoor retail, hospitality and residential lighting applications. Offered with wattages of 9 W, 19 W and 29 W, CHI LEDs can supplement direct luminaires and spotlights with dynamic color temperature variability and allow the seamless setting of any desired color temperature between 2700K and 5700K. The Color Choice Series’ seamlesscolor temperature tunability is achieved by subdividing the COB into two electrically insulated segments for warm white 2700K and cool white 5700K which can be controlled/driven independently from each other. Each circuit requires a separate power supply unit or a co-channel power supply.
The Color Choice Series is ideal for elegant and simple mood lighting, adjustment to changing daylight and decorative lighting aspects in private homes, stores, hotels and bars. CHI COBs are suited for with large spot lights in retail applications or smaller directional lamps like MR16, PAR20, PAR30, PAR38 lamps for general lighting use.
All Chip-on-Board LEDs from Everlight have completed LM80 lumen maintenance testing.
Samples are available now with production volume being planned for Q3/2014.
