Abstract:
The light-emitting device includes a substrate and a plurality of light-emitting sections. A first light-emitting section is made up of LED chips and a first fluorescent-substance-containing resin layer, and a second light-emitting section is made up of LED chips and a second fluorescent-substance-containing resin layer. The first fluorescent-substance-containing resin layer and the second fluorescent-substance-containing resin layer are provided in a plurality of locations such that the fluorescent-substance-containing resin layers for the different light-emitting sections are adjacently arranged.
