Abstract:
Provided is a light-emitting device that is able to adjust a color temperature by power supplied from a single power source. The light-emitting device includes an anode electrode land, a cathode electrode land, and three or more wires that are provided in parallel and are connected to the anode electrode land and the cathode electrode land, in which at least three wires among the three or more wires have different forward current-forward voltage characteristics and are connected to different light emitting portions, and the color temperature of light emitted from the whole of the light-emitting portions is able to be adjusted.
