Lumileds launches fourth generation of LUXEON CoB Core LEDs, boosting 90CRI performance by 12%

LED maker Lumileds of San Jose, CA, USA has introduced its fourth generation of LUXEON CoB (chip-on-board) Core Range LEDs, with what is claimed to be 5% greater efficacy than the nearest competitors.

In particular, efficiency is not compromised at high color rendering index (CRI). “The goal of Lumileds is to address the industry-wide issue of the efficiency gap between 80 and 90CRI CoBs,” says Eric Senders, product line director for the LUXEON CoB Family. “With this new generation, we have limited this gap tremendously by increasing the 90CRI performance by 12% over the previous generation,” he adds. “In the past, there was a tradeoff between light quality and efficiency, but customers no longer need to make that sacrifice with these products.”

Lumileds says that its ability to deliver luminous efficacy exceeding 130lm/W at 90CRI (and over 170lm/W at 70CRI) is largely due to its own phosphor development and engineering coupled with precise process and manufacturing controls at its manufacturing facilities.

Lumileds has hence also improved the thermal resistance of the CoBs by 25% further reducing the burden on heat sinks and shrinking the size of optics at the system level. The result is high fixture efficacy and smaller fixtures.

The LUXEON CoB Core Range (Gen 4) will be on display at the Light + Building show in Frankfurt, Germany (18-23 March).
