1. A light-emitting apparatus comprising:

  • a board;

    a resin frame fixed on the board;

    a plurality of sets of light-emitting elements which are mounted in a region on the board surrounded by the resin frame, wherein the light-emitting elements configuring each of the sets are connected in series to each other;

    a plurality of pairs of connection electrodes which are provided on the board, and electrically connected to the plurality of sets of light-emitting elements and capable of supplying a drive current selectively to some of the plurality of sets of light-emitting elements; and

    a sealing resin which comprises a phosphor mixed therein and excited by light from the plurality of sets of light-emitting elements, and is filled in such a way as to bury the region on the board surrounded by the resin frame, to seal integrally the plurality of sets of light-emitting elements with a single sealing resin,wherein a thickness of the sealing resin immediately above the plurality of sets of light-emitting elements differs for the respective sets, and thereby, a chromaticity of light emitted from the sealing resin differs when each of the sets of light-emitting elements emits the light singly,wherein the light-emitting elements within each of the sets are placed at the same depth from an upper surface of the sealing resin, and the light-emitting elements of different sets are placed at different depths from the upper surface of the sealing resin.
