LED Luminaries

LED news and insight from our technology editor Steve Bush, who has been messing with LED lighting for more years than he would care to remember.

More on Cree’s 200 lm/W luminaire

We would like a photo please :-)Last week Electronics Weekly reported on a 200 lm/W technology demonstrator luminaire from Cree.

We asked for details and photos, but Cree said sorry, no.

However, a very nice PR woman for Cree managed to get us a bit more information on what must be a fascinating design:

“Cree developed the prototype to create the first demonstration luminaire fixture to achieve 200 lm/W. The concept luminaire accounts for all electrical, thermal and optical losses and delivers a system efficacy of 200 lm/W. It was tested in a NVLAP-certified lab, and third party approved. While this prototype is not designed for the commercial market, Cree’s past track record shows that it can take about two years from R&D achievement to commercialisation.”

    Hi Suijin.
    How did you find that lot out?

    And Steve,
    I like the early information release.
    And just wish they had released a bit more of it :-)

    The LEDs are available now, not the total luminaire though.

    They are the MK-R LED. Keep in mind the 200lm/W was taken at 1W, 25°C. At max current they are more like 110 lm/W.

    There’s nothing quite as alluring as the new technology that’s just around the corner! Just don’t peek around the corner, though…

    I understand the desire to stay in public view and remind people that Cree is still breaking new ground, but I’d rather see a press release stating that the new LED is now on the market.
