For these types of applications, an LED light source must exhibit compact size, high efficiency, sufficient lumen output, high CRI, high color uniformity, and proper light distribution to maintain a comfortable and uniform lighting environment – all at consumer acceptable prices. With its new COB Ju Series, EVERLIGHT ELECTRONICS has created the other ideal LED to address major challenges posed when designing a retrofit like MR, GU or candelabra type: minimum efficiency requirements, thermal management in limited space, and complexity of design.
EVERLIGHT’s COB series is a 3.7W multi chip, ceramic substrate based LED that boasts a low thermal resistance (Rth <1.8°C/W) and superior efficacy of 100lm/W at 3000K CCT and high CRI (>80Ra). It will be available not only in ANSI 3000K CCT but in all Energy Star / ANSI color temperature ranges. Mechanically, the COB Ju series can be mounted directly on heat sink eliminating the SMT process. This provides more direct thermal dissipation, ease of assembly, and lowering of the system cost in lighting applications.
EVERLIGHT COB Ju Series is using the standard DC chips configured in series and parallel to provide the most convenient driving conditions for existing driver designs. Also, with a ceramic substrate, users can have higher reliability and better thermal dissipation. The COB Ju Series also can achieve the low cost of industry target, >400lm/$ for a COB LED light source. This is a superb single emission area COB LED that needs to be used.
