Lumileds Next Generation CoB LEDs - New Quality of Light Breakthrough at High Efficiency

Today Lumileds introduced its fourth generation of chip-on-board (CoB) LEDs, the Luxeon CoB Core Range, which leads the market in efficacy and quality of light. With the new Luxeon CoB Core Range, Lumileds sets a new standard with 5% greater efficacy than the nearest competitors. Most impressively, efficiency is not compromised at high color rendering index.

“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,” said Eric Senders, Product Line Director for the Luxeon CoB Family.

Lumileds ability to deliver outstanding efficacy exceeding 130 lm/W in 90CRI (and over 170 lm/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. 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, March 18-23.
