P3D Re: Stereo Mounting Services 6/98

I hadn't thought that blue LED's were that efficient for use in producing a
multi-LED  white LED (as well has having to have multi-elements which wouldn't
help cost either).

But maybe the following "LED" (really a fluorescent lamp of sorts) would work.

Anybody try one?  How would one distribute the light evenly in a viewer
with what's probably a directional point source?

NICHIA CHEMICAL has developed a highly efficient white LED lamp. Based on a blue LED 
developed in 1993, the white LED lamp incorporates a YAG (yttrium aluminum garnet) 
fluorescent layer to emit white light. The white lamp has the brightness of 5 
lumen per 1W; two units of the lamp will be brighter than the automotive interior 
roof lamp. It is sample-priced at 300 yen ($2.73) apiece in lots of 100, and 
NICHIA will start volume shipment in early October, targeting car- mount panels, 
LED back lights and many other applications.
