Remote Phosphor Module Delivers 203 Lm/W

Intematix and Philips Lumileds collaboration delivers remote phosphor LED lighting module with 203 lumens per watt efficacy



Intematix Corporation, a manufacturer of phosphor solutions and Philips Lumileds, an LED supplier has announced a remote phosphor-based LED lighting module with 203 lumens per watt efficacy. It is believed that this module represents the highest level of efficacy among LED-based light sources commercially available for production in the market today.


 "This result is a significant step along our innovation roadmap for phosphor solutions," said Yi-Qun Li, Chief Technology Officer at Intematix. "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 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.

This ground-breaking lighting module uses Philips Lumileds LUXEON T/TX family of royal blue LEDs, achieving industry leading wall plug efficiencies of 76%.

"We're very proud of this landmark performance of 203 lm/W as this was achieved using our latest commercially available LED technology and Intematix's remote phosphor," said Jy Bhardwaj, Senior Vice President 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 like replacement lamps, high bay industrial illumination and linear applications like commercial lighting. By increasing efficacy, remote phosphor reduces material and operating costs.


AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
