Abstract
Provided is a light-emitting apparatus including a board, a resin frame fixed on the board, sets of light-emitting elements mounted in a region on the board surrounded by the resin frame, wherein the light-emitting elements configuring each set are connected in series to each other. The light-emitting apparatus further includes connection electrodes provided on the board and electrically connected to the light-emitting elements and capable of supplying a drive current selectively to the sets of light-emitting elements, and a sealing resin which includes a phosphor mixed therein and excited by light from the light-emitting elements, and is filled so as to bury the region on the board, to seal integrally the light-emitting elements. The thickness of the sealing resin immediately above the light-emitting elements differs for the respective sets, and thereby, a chromaticity of light emitted from the sealing resin differs when each set of light-emitting elements emits the light singly.
