Abstract:
1. A light emitting device comprising: a substrate; a plurality of light emitting elements provided on a primary surface of the substrate; at least one protective element connected in parallel with the plurality of light emitting element; a resin frame made of a resin having a low optical transmittance, the resin frame being provided annularly on the primary surface of the substrate so as to surround a mounting area in which the plurality of light emitting elements are provided; a fluorescent-material-containing resin layer made of a resin containing fluorescent materials, the fluorescent-material-containing resin layer being provided adjacent to an inner side of the resin frame so as to cover the plurality of light emitting elements; and at least one first light emitting element connection electrode and at least one second light emitting element connection electrode, which are provided on the primary surface of the substrate so as to face each other along a first direction in the primary surface, the plurality of light emitting elements having such a circuit configuration that at least two series circuit sections, in each of which at least two of the plurality of light emitting elements are connected in series, are connected in parallel between the at least one first light emitting element connection electrode and the at least one second light emitting element connection electrode, the at least two series circuit sections being aligned along a second direction orthogonal to the first direction in the primary surface, between the at least one first light emitting element connection electrode and, the at least one second light emitting element connection electrode, the at least two of the plurality of light emitting elements in each of the at least two series circuit sections being aligned along the first direction, the at least one first light emitting element connection electrode and the at least one second light emitting element connection electrode being disposed below at least one of the resin frame and the fluorescent-material-containing resin layer.
