To replace 40W and 60W incandescent A-bulbs, LED A-lamps need a light source that exhibits high efficiency, sufficient lumen output, high CRI, color uniformity, and sufficient light distribution to maintain a comfortable and uniform lighting environment – all at consumer acceptable prices. With its new COB Series, Everlight Electronics has created an ideal LED to address major challenges posed when designing an LED A-bulb: heat dissipation, color shift over time and temperature, light distribution and cost.
Everlight’s COB LED series is a MCPCB substrate based multi-chip solution that boasts a >95lm/W at 3000K CCT and >80 CRI. Less layers of thermal resistance result in lower overall junction temperature. A new patent pending Everlight innovation is able to address the Hot/Cold Factor, the color uniformity as related to change in temperature. From 25°C to 85°C, the Everlight COB LED can control CCT shift to within 200K CCT for all wattages - the first of its kind that is able to restrict the shift to such a narrow range. A large single light emitting source means less diffusion needed to achieve high uniformity and light distribution. And finally, due to high performance, aggressive commercial strategy, and less processes and material required for assembly, the Everlight chip-on-board technology has nearly achieved the industry target of 200lm/$ for LED light sources.
Everlight is fostering closer working relationships between our R&D, Sales and Marketing teams to meet and exceed our customer’s expectations in both product offering and technology. The COB LED Series is expected to satisfy the fast-growing market of general lighting LED replacement applications.
