Lumileds has introduced its fourth generation of chip-on-board (CoB) LEDs, the Luxeon CoB Core Range, with 5% greater efficacy than the nearest competitors, according to the company. Efficiency is not compromised at high color rendering index.
The 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 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 Luxeon CoB Core Range (Gen 4) will be on display at the upcoming Light + Building show in Frankfurt, Germany, 18–23 March.
