Directional and decorative COB LEDs revealed by Everlight
The Taiwanese firm's latest nitride based LED series are claimed to offer low thermal resistance and high performance. The C52 Series also can achieve the low cost of industry target of over 400lm/$ for a COB LED light source.
Everlight is marketing its 6.4W and 8W Chip-on-Board (COB) LED series, which it claims is one of the highest CRI and highest efficiency COBs on the market.
The brand new and smaller C52 COB LED series is suited for directional and decorative applications such as MR lamps and P35 bulbs.

For these types of applications, an LED light source must exhibit compact size, high efficiency, sufficient lumen output, high CRI, high colour uniformity, and proper light distribution to maintain a comfortable and uniform lighting environment, all at consumer acceptable prices.
Everlight boasts its new C52 COB Series has created another ideal LED to address major challenges posed when designing a retrofit like MR, GU or candelabra type, with 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 colour temperature ranges.
Mechanically, the C52 COB 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’s C52 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 firm will be showcasing its products, including its C52 COB LEDs, at LIGHTFAIR International 2012 at booth #4117, taking place in Las Vegas, U.S.A. between 9th and 11th May 2012.
