Assignee: NICHIA CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC G  H  F | IPC F  H

Claim 4:
5. A light-emitting circuit, comprising:
first light-emitting elements;
second light-emitting elements; and
resistance elements,
wherein a color temperature of light emitted from the second light-emitting elements is different from a color temperature of light emitted from the first light-emitting elements,
wherein an anode side terminal of a first circuit and an anode side terminal of a second circuit are connected to a first terminal of a direct-current power supply, the first circuit including the first light-emitting elements and the resistance elements, the first light-emitting elements and the resistance elements being connected in series in the first circuit, the second circuit including the second light-emitting elements,
wherein a cathode side terminal of the first circuit and a cathode side terminal of the second circuit are connected to a second terminal of the direct-current power supply,
wherein a luminous flux of the first light-emitting elements increases as a current input from the direct-current power supply increases in case that the current is less than a first current value,
wherein a luminous flux of the second light-emitting elements increases as the current increases in case that the current is more than a second current value, and
wherein the second current value is less than the first current value.
