Semiconductor light emitting device

Abstract

A light emitting device can make it hard for fluorescence emitted from each phosphor in a color conversion plate to be absorbed by other phosphor. The color conversion plate can include multiple types of phosphors, and the light from a light emitting element can be allowed to reach each of the phosphors efficiently. The color conversion plate can contain at least first and second phosphors which absorb light emitted from the light emitting element and outputs fluorescence. The color conversion plate can have multiple first regions containing the first phosphor on a light emitting element side, being arranged with a predetermined spacing therebetween, and second regions containing the second phosphor on the upper surface, being arranged with a predetermined spacing therebetween. A region where the first regions and the second regions are excluded, as viewed from a location on top of the conversion plate, contains no phosphor.
