Abstract
A lighting apparatus is provided that, while suppressing an increase in size, can change the illuminating direction. The lighting apparatus has: a laser generator which emits laser light; a light emitting member which is irradiated with the laser light emitted from the laser generator to emit light; an irradiated position changer which moves and thereafter stops an irradiated position at which the light emitting member is irradiated with the laser light; and a light projecting member which projects the light emitted from the light emitting member.
Claims18
A lighting apparatus comprising:
- a laser generator which emits laser light;
- a light emitting member which is irradiated with the laser light emitted from the laser generator to emit light;
- an irradiated position changer which moves and thereafter stops an irradiated position at which the light emitting member is irradiated with the laser light;
- and
- a light projecting member which projects the light emitted from the light emitting member,
- wherein the light projecting member comprises a first reflector having a reflective surface which reflects the light emitted from the light emitting member,
- the reflective surface is formed in a shape having a focal point, and
- the light emitting member is disposed in a region including the focal point of the reflective surface or near the focal point of the reflective surface.
A lighting apparatus comprising:
- a laser generator which emits laser light;
- a light emitting member which is irradiated with the laser light emitted from the laser generator to emit light;
- an irradiated position changer which moves and thereafter stops an irradiated position at which the light emitting member is irradiated with the laser light;
- a light projecting member which projects the light emitted from the light emitting member;
- and
- a light guide member which guides the laser light emitted from the laser generator to the light emitting member,
- wherein the light guide member includes a lens that transmits the laser light, and
- the irradiated position changer changes the irradiated position on the light emitting member by changing an angle of the lens.
A lighting apparatus comprising:
- a laser generator which emits laser light;
- a light emitting member which is irradiated with the laser light emitted from the laser generator to emit light;
- an irradiated position changer which moves and thereafter stops an irradiated position at which the light emitting member is irradiated with the laser light;
- and
- a light projecting member which projects the light emitted from the light emitting member,
- wherein the light projecting member comprises a light projecting lens which controls the light emitted from the light emitting member, and
- the light projecting member is configured so that the light emitted from the laser generator enters the light projecting lens through a region including a focal point of the light projecting lens or near the focal point of the light projecting lens.
