Abstract

A vehicle lamp such as a rear combination lamp comprising: a reflex reflector lens that is fitted in a front lens of the lamp so as to reflect the light from the outside the vehicle lamp back to the outside, and a light reflector that is formed in the front lens so as to face the reflex reflector lens and to entirely reflect the light from a light source toward the light source. The vehicle reflex reflector lens is made of a material that has a lower heat resistance than the front lens.

Claims

1. A vehicle lamp provided with a lamp body and a lens that form a lamp chamber, comprising:

a reflex reflector lens which is an element independent from said lens, and

a light reflection means provided in said lens so as to face said reflex reflector lens and to reflect light emitted from a light source toward said light source.

2. The vehicle lamp according to claim 1, wherein said light reflection means is provided so as to face said light source.

3. The vehicle lamp according to claim 1, wherein said light reflection means is a reflective step formed in said lens and provided between said reflex reflector lens and said light source.

4. The vehicle lamp according to claim 2, wherein said light reflection means is a reflective step formed in said lens and provided between said reflex reflector lens and said light source.

5. The vehicle lamp according to claim 3, wherein said reflection step comprises cone-shaped steps.

6. The vehicle lamp according to claim 1, wherein said reflex reflector lens is formed of a material having a lower heat resistance than said lens.

7. The vehicle lamp according to claim 2, wherein said reflex reflector lens is formed of a material having a lower heat resistance than said lens.

8. The vehicle lamp according to claim 3, wherein said reflex reflector lens is formned of a material having a lower heat resistance than said lens.

9. The vehicle lamp according to claim 5, wherein said reflex reflector lens is formed of a material having a lower heat resistance than said lens.

11. The vehicle lamp according to claim 8, wherein said reflection step formed on said reflex reflector lens and said reflection steps formed on said light reflecting section respectively comprises a plurality of cone-shaped steps formed thereon.

12. The vehicle lamp according to claim 8, wherein said reflex reflector lens is formed of a material having a lower heat resistance than said lens.

10. A vehicle lamp provided with a lamp body and a lens that form a lamp chamber and a light source provided in said lamp body, said vehicle lamp comprising:

a light reflecting section formed in said lens so as to face, with one side thereof, said light source and reflect light emitted from said light source toward said light source; and

a reflex reflector lens fitted inside said light reflecting section, and wherein

said reflex reflector lens is formed with a reflective step and said light reflecting section is formed, on another side thereof, with a reflective step that faces said reflective step formed on said reflex reflector lens.
