Abstract

A vehicle lamp includes a first light source, a second light source, a first reflector configured to reflect light from the first light source toward the front of the lamp, a second reflector configured to reflect light from the second light source toward the front of the lamp, and a first shade configured to shield at least a part of direct light directed from the first light source to the outside of the lamp. The first shade includes a reflecting surface configured to reflect the light from the second light source toward the front of the lamp.

First claim

What is claimed is:

1. A vehicle lamp comprising:
a first light source;
a second light source;
a first reflector configured to reflect light from the first light source toward a front of the lamp;
a second reflector configured to reflect light from the second light source toward the front of the lamp; and
a first shade configured to shield at least a part of direct light directed from the first light source to an outside of the lamp,
wherein the first shade includes a reflecting surface having a rotational paraboloid shape and configured to reflect the light from the second light source toward the front of the lamp.

2. The vehicle lamp of claim 1 , wherein the reflecting surface is configured to reflect the light from the second light source in a direction that is substantially the same as the light from the first light source reflected by the first reflector.

3. The vehicle lamp of claim 2 , further comprising a second shade configured to shield at least a part of direct light directed from the second light source to the outside of the lamp,
wherein the second shade includes a reflecting surface configured to reflect the light from the first light source toward the front of the lamp.

4. The vehicle lamp of claim 1 , wherein the rotational paraboloid shape has a focal point at or near the second light source.

5. The vehicle lamp of claim 4 , further comprising a second shade configured to shield at least a part of direct light directed from the second light source to the outside of the lamp,
wherein the second shade includes a reflecting surface configured to reflect the light from the first light source toward the front of the lamp.

6. The vehicle lamp of claim 1 , further comprising:
a second shade configured to shield at least a part of direct light directed from the second light source to the outside of the lamp,
wherein the second shade includes a reflecting surface configured to reflect the light from the first light source toward the front of the lamp.

7. The vehicle lamp of claim 1 , wherein the first light source and the second light source are disposed such that light exit surfaces thereof face each other, and
wherein each of the first and second reflectors has a rotational paraboloid shape having a focal point at or near the first or second light source, and does not protrude to a lamp front side from the first or second light source.

8. The vehicle lamp of claim 1 , wherein a front end portion of the first reflector and a front end portion of the second reflector are connected.

9. The vehicle lamp of claim 1 , wherein the first light source faces the second light source such that an optical axis of the first light source is substantially parallel to an optical axis of the second light source.

10. The vehicle lamp of claim 1 , wherein an optical axis of the first light source is not parallel to an optical axis of the second light source.

11. A vehicle lamp comprising:
a first light source;
a second light source;
a first reflector configured to reflect light from the first light source toward a front of the lamp;
a second reflector configured to reflect light from the second light source toward the front of the lamp; and
a first shade configured to shield at least a part of direct light directed from the first light source to an outside of the lamp,
a second shade configured to shield at least a part of direct light directed from the second light source to the outside of the lamp,
wherein the first shade includes a reflecting surface configured to reflect the light from the second light source toward the front of the lamp and the second shade includes a reflecting surface configured to reflect the light from the first light source toward the front of the lamp.

12. The vehicle lamp of claim 11 , wherein the reflecting surface has a rotational paraboloid shape having a focal point at or near the second light source.

13. The vehicle lamp of claim 11 , wherein a front end portion of the first reflector and a front end portion of the second reflector are connected.

14. The vehicle lamp of claim 11 , wherein the first light source faces the second light source such that an optical axis of the first light source is substantially parallel to an optical axis of the second light source.

15. The vehicle lamp of claim 11 , wherein an optical axis of the first light source is not parallel to an optical axis of the second light source.
