Abstract:
There is provided a light-emitting device including an anode electrode land, a cathode electrode land, and a first light-emitting unit and a second light-emitting unit electrically connected to the anode electrode land and the cathode electrode land and provided in parallel to each other, in which the first light-emitting unit and the second light-emitting unit each include blue light-emitting LED chips, the first light-emitting unit and the second light-emitting unit have different amounts of change in luminous flux with respect to an amount of change in current applied between the anode electrode land and the cathode electrode land, and a color temperature generated from an entire light-emitting unit including the first light-emitting unit and the second light-emitting unit can be adjusted.
