Efficient 36V XUAN high-power COBs for easy assembly in LED spotlight and downlight designs
Color Choice© Series of tunable CHI COBs for indoor retail and residential lighting environments
Shulin, New Taipei City 【2014.12.17】–EVERLIGHT ELECTRONICS CO., LTD. 【TSE:2393】, a leading player in the global LED and optoelectronics industry, announces two new Chip-on-Board LED families, the XUAN series of high-power COBs and the Color Choice® (Color on Demand) COB series CHI.
EVERLIGHT’s high-power (36V) XUAN COB series offers the dual benefit of high efficiency and easy assembly. Covering a wide wattage range at customers' preference from 2-50W 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 (9-29W) 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 >110lm/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 9W, 19W and 29W, 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.
This makes the Color Choice® Series 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. A complete line of accessories such as standardized holders, appropriate reflectors and more is available in the aftermarket.
