Abstract
Official abstract text for this publication.
A first LED emits visible light of an emission color such that with respect to a CIE(1976)L*u*v* color space chromaticity diagram, the chromaticity is exterior to a prescribed white light region wherein the absolute value of a deviation duv from the blackbody radiation locus is at most 0.02 and the color temperature is within a range of from 2,500K to 10,000K, and the deviation duv from the blackbody radiation locus is larger than 0.02, and a second LED emits visible light of an emission color such that with respect to the above chromaticity diagram, the chromaticity is exterior to the prescribed white light region, and the deviation duv from the blackbody radiation locus is smaller than −0.02.
First claim
Opening claim text (preview).
What is claimed is: 1. An LED light emitting device which radiates a combined light obtained by combining visible light emitted from first LED and visible light emitted from second LED, comprising: a drive controller unit that respectively controls a first drive current to be supplied to the first LED and a second drive current to be supplied to the second LED, wherein the first LED emits visible light of an emission color such that with respect to a CIE (1976) L*u*v* color space…
