Abstract
A lighting unit includes a first light source, a second light source, a projection lens, a first reflector that reflects light from the first light source, a second reflector that reflects light from the second light source, a shade section, and a reflecting section. The shade section is movable between a first position at which at least a part of the light from the second reflector is shielded and a second position which is spaced apart from the first position. The reflecting section reflects a part of the light reflected from the second reflector when the shade section is at the first position.
Claims8
A lighting unit comprising:
- a first light source;
- a second light source;
- a projection lens;
- a first reflector that reflects light generated by the first light source toward a first area of the projection lens;
- a second reflector that reflects light generated by the second light source toward a second area on the projection lens, the second area including at least a part of the first area;
- a shade section disposed to be movable between a first position at which at least a part of the light which is incident onto the first area from the second reflector is shielded and a second position which is spaced apart from the first position;
- and
- a reflecting section that reflects and guides a part of the light reflected from the second reflector to a region within the second area when the shade section is at the first position.

- and
- a reflecting section that reflects and guides a part of the light reflected from the second reflector to a region within the second area when the shade section is at the first position,
- wherein the shade section extends in a direction across an optical axis when the shade section is at the first position,
- wherein the reflecting section extends in a direction parallel to the optical axis when the shade section is at the first position,
- wherein the reflecting section positions adjacent to a focus of the second reflector when the shade section is at the first position,
- wherein the first reflector and the second reflector are disposed such that the optical axis passes between the first reflector and the second reflector,
- wherein the first light source is disposed at a side of the second reflector with respect to the optical axis,
- wherein the second light source is disposed at a side of the first reflector with respect to the optical axis,
- wherein the second area is an area that is formed around the first area, and
- wherein the first reflector is disposed in a position different from the second reflector in a direction of the optical axis.
