LIGHT EMITTING APPARATUS AND METHOD FOR MANUFACTURING SAME
First Claim
1. A light emitting apparatus comprising:
- a substrate; and
first and second light emitting sections provided on the substrate so as to be adjacent to each other,the first light emitting section being made up of (i) at least one first blue LED chip which emits blue light and (ii) a resin which covers the at least one first blue LED chip and in which a red phosphor is dispersed that emits red light upon receipt of excitation light from the at least one first blue LED chip,the second light emitting section being made up of at least one second blue LED chip which emits blue light.

Abstract
A light emitting apparatus of the present invention is configured such that first and second light emitting sections are provided on a substrate (101) so as to be adjacent to each other, the first light emitting section being made up of (i) at least one blue LED chip (102) and (ii) a resin layer which covers the at least one blue LED chip (102) and in which a red phosphor is dispersed that emits red light upon receipt of excitation light from the at least one blue LED chip (102), the second light emitting section being made up of at least one LED chip (102). This makes it possible to easily adjust, with a simple and compact configuration, a ratio between a quantity of blue light and a quantity of red light.

10. A method of manufacturing a light emitting apparatus, comprising the steps of:
-
(a) bonding, to a substrate, a plurality of blue LED chips each of which emits blue light; and (b) forming a phosphor-containing resin layer, which constitutes a first light emitting section, in a first region on the substrate so that the phosphor-containing resin layer seals, with a resin, at least one of the plurality of blue LED chips which one is provided in the first region, in which resin a red phosphor is dispersed that emits red light upon receipt of excitation light from the at least one of the plurality of blue LED chips, wherein a light emitting section, made up of at least one of the plurality of blue LED chips which one is provided in a second region adjacent to the first region on the substrate, serves as a second light emitting section. - View Dependent Claims (11, 12)
