@Winfield Hill: ditto, I would love to see a detailed datasheet. Blurbs like these do nothing other than announce a product! @Ryszard.Milewicz: I suspect it is a solution with strips of LED arrays spaced as needed by packaging/thermal considerations and not individual LED chips. That is why it may be difficult to add other wavelength light sources you describe. Either way, the trick in containing thermal issues in an array of LEDs is to switch & drive each/groups of LEDs alternately so that the light output remains the same while the temperatures can be contained.

As this is multi-chip package, adding some amber chips inside package should improve warm white efficiency up to cold white levels (as currently Osram did).

Wow, small 46-volt 6-watt LEDs, cool! Hey guys, the link doesn't give us the datasheet we're craving, but merely a 2-page blurb. How about also including a link to the manufacturer's web page in your stories, that'll help us get what we need. You know, like http://www.cree.com/

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
