Next-gen CoB LEDs offer five percent greater efficiency

A range of fourth generation chip-on-board (CoB) LEDs has been introduced by Lumileds. The company claims that the LUXEON CoB Core Range leads the market in efficacy and quality of light. With the new LUXEON CoB Core Range, Lumileds sets a new standard with five percent greater efficacy than the nearest competitors. Efficiency is not compromised at high colour rendering index.

Eric Senders, Product Line Director for the LUXEON CoB Family, said: “The goal of Lumileds is to address the industry-wide issue of the efficiency gap between 80 and 90CRI CoBs.

"With this new generation, we have limited this gap tremendously by increasing the 90CRI performance by 12% over the previous generation.

"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 ability to deliver outstanding efficacy exceeding 130lm/W in 90CRI (and over 170lm/W in 70CRI), is largely the result of Lumileds own phosphor development and engineering coupled with precise process and manufacturing controls at the company’s manufacturing facilities.

Due to these improvements, Lumileds 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. According to Lumileds, the result is exceptional fixture efficacy and smaller fixtures.

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