New 1W led from Osram

Osram Opto Semiconductors Announces World's First High-Performance LED in Compact Package

[ QUOTE ]
The new offering, called "Golden Dragon," delivers a concentrated light point with a high degree of efficiency (optical efficiency is 20 lm/W), all in a compact package (0.8 – 1.8 mm high and fitting inside an enclosure measuring 6 x 7 mm). While individually larger in size than conventional LEDs (with a chip size of 700 µm, it is twice the size of the Power TOPLEDÒ), six Power TOPLEDs would be required to match the lighting intensity of a single Golden Dragon. This would represent a four-fold increase in space required if a conventional LED was used.

Too bad it is still in prototype and only red & yellow will be available by mid-2003. At least we will have more choices of 1W led other that lumined's. /ubbthreads/images/graemlins/grin.gif

Nice!!! Now we'll have 3 choices, since we're also going to get 2W LEDs from Nichia.

OK, have to keep our eyes open on that one then. Wonder how the pricing will compare to the 2W Nichia and LumiLED's LS.

All I want is price drops on those flashlights with 1W led, because at this moment they are just way too expensive for me. /ubbthreads/images/graemlins/icon23.gif

Is there an article/link about the 2W Nichia?

We make a nice 1W adapter for only $20, complete flashlight for $30

Just a thread on it from Shot Show here.

Thanks Lux

That 2W Nichia looks sweet with nice packaging.

McGizmo has put up a nice page about the Nichia 2W. /ubbthreads/images/graemlins/thumbsup.gif

Nichia NCCW023E 2 Watt LED.

he'd better chime in here with some more information that that /ubbthreads/images/graemlins/mad.gif

I've had the pleasure of viewing a sample of Osram's 1W white LED about a month ago (mounted alongside red and amber 1-watters on an MCPCB, part of an Osram demo kit powered by AAs). The specimen I saw had no visible primary optics (unlike the 30-deg nichia 2W), but otherwise looked pretty much like a cross between a luxeon and the nichia 2W with a square white ceramic casing (like the nichia) and 2 sturdy legs sticking out radially opposite each other (like a luxeon).

I'd characterize the output to be around that of a N4 luxeon .ie. not particularly bright, slight violet color. Optics may alter that in actual practice, though.

I have hopes that both the Nichia 2W and this Osram become viable alternatives to the Lumileds item soon. News is also about more high-powered LEDs coming from mfgs other than Lumileds, Osram and Nichia - the floodgates of SSL are about to bust open! /ubbthreads/images/graemlins/grin.gif
