Abstract
Official abstract text for this publication.
A light-emitting module including: a first light source including a first light-emitting element and a wavelength converter and emitting visible light having a chromaticity within rectangle range ABCD, the wavelength converter changing a wavelength of a portion of light emitted by the first light-emitting element; and a second light source including a second light-emitting element and emitting red light. The light-emitting module emits white light by mixing the visible light and the red light, and satisfies conditions 2.0≦(S L −S H )/(F L −F H )≦3.0 and 0.01≦((x L −x H ) 2 +(y L −y H ) 2 ) 1/2 ≦0.02.
First claim
Opening claim text (preview).
The invention claimed is: 1. A light-emitting module that emits white light generated by mixing red light and visible light of a color other than red, comprising: a first light source including a first light-emitting element and a wavelength converter and emitting the visible light, the wavelength converter changing a wavelength of a portion of light emitted by the first light-emitting element, the visible light having a chromaticity within rectangle range ABCD defined by coordina…
