Intematix and Lumileds announce remote phosphor LED lighting module delivering 203lm/W

Intematix Corp of Fremont, CA, USA, which makes customizable, patented phosphors and remote phosphor components for LED lighting, and LED maker Philips Lumileds of San Jose, CA, USA have announced a remote-phosphor-based LED lighting module with luminous efficacy of 203 lumens per watt, which is reckoned to be the highest among LED-based light sources commercially available for production on the market.

“This result is a significant step along our innovation roadmap for phosphor solutions,” says Intematix’s chief technology officer Yi-Qun Li. “Remote phosphor architectures lower cost, increase efficacy and improve light quality in many of the consumer, commercial, industrial and outdoor area lighting applications commonly deploying LED technology today.”

The LED lighting module uses a commercially available 26mm-diameter dome-shaped remote phosphor developed by Intematix that converts blue light to on-the-black-body-line 6000K daylight spectrum and 70CRI (color rendering index) with conversion efficacy of 267 lumens per radiant watt. The design is applicable for round and linear module configurations and is offered in color temperatures ranging from 2700K to 6000K with CRI values from 70 up to 98.

The lighting module uses Lumileds’ LUXEON T/TX family of royal blue LEDs, achieving wall-plug efficiencies of 76%.

The efficacy of 203lm/W was achieved using Lumileds’ latest commercially available LED technology and Intematix’s remote phosphor, notes Jy Bhardwaj, senior VP of R&D at Philips Lumileds. “This marquee performance simplifies a wide variety of thermally constrained applications such as 100W A19 bulbs and high-lumen candle lamps, and enables downlights with the highest efficacy in the industry.”

Remote phosphor solutions are notable for delivering high-quality, uniform light and omni-directional light distribution to applications such as replacement lamps, high-bay industrial illumination and linear applications like commercial lighting. By increasing efficacy, remote phosphor reduces material and operating costs, says Intematix.
