Abstract
A lighting device includes a first light emitting element, a second light emitting element, and a driving circuit driving the first light emitting element and the second light emitting element. The driving circuit includes a current supply supplying currents to the first light emitting element and the second light emitting element, a first current controller controlling a magnitude of a first current supplied from the current supply to the first light emitting element, and a second current controller controlling a magnitude of a second current supplied from the current supply to the second light emitting element.
Claims4
A lighting device comprising:
- a first light emitting element;
- a second light emitting element;
- and
- a driving circuit that drives the first light emitting element and the second light emitting element,
- wherein the driving circuit includes:
- a current supply that supplies currents to the first light emitting element and the second light emitting element,
- a first current controller that controls a magnitude of a first current supplied from the current supply to the first light emitting element,
- a second current controller that controls a magnitude of a second current supplied from the current supply to the second light emitting element, and
- a luminance control signal detector circuit that:
- detects a luminance control signal input from outside, the luminance control signal including first luminance information of the first light emitting element and second luminance information of the second light emitting element,
- outputs the first luminance information to the first current controller, and
- outputs the second luminance information to the second current controller.
