Patent ID: 8348457

Claim:
A lighting device, comprising: a plurality of first light-emitting diodes each including a plurality of first blue light-emitting diode elements, a first resin sealing the plurality of blue light-emitting diode elements, a first phosphor included in the first resin to receive a part of blue light from the first blue light-emitting diode elements and emit first phosphor-converted light, the plurality of first light-emitting diodes each emitting a first white light that comprises blue light from the first blue light-emitting diode elements and first phosphor-converted light, and the first white light having a first correlation color temperature; a plurality of second light-emitting diodes each including a plurality of second blue light-emitting diode elements, a second resin sealing the plurality of second blue light-emitting diode elements, a second phosphor included in the second resin to receive a part of blue light from the second blue light-emitting diode elements and emit second phosphor-converted light, the plurality of second light-emitting diodes each emitting a second white light that comprises blue light from the second blue light-emitting diode elements and second phosphor-converted light, the second white light having a second correlation color temperature; a heat dissipation plate; and the plurality of first light-emitting diodes and the plurality of second light-emitting diodes being provided in pairs with respect to each other, one of the first light-emitting diodes and one of the second light-emitting diodes in one of the pairs being mounted on the heat dissipation plate as a combination light-emitting diode, and the first correlation color temperature being higher than the second correlation color temperature.
