Abstract

An Fr turn lamp that is a vehicle lamp includes a first light guide and a second light guide. The first light guide is disposed in front of a light source in the direction of an optical axis. The second light guide has a connection end connected to a vehicle width direction outer side surface of the first light guide and extends outward in the vehicle width direction from the connection end. The first light guide has a reflecting surface configured to reflect a part of incident light from the light source toward the connection end of the second light guide.

First claim

The invention claimed is:

1. A vehicle lamp comprising:
a light source which has an optical axis provided along a vehicle longitudinal direction;
a first light guide which is disposed along the optical axis of the light source and along a vehicle longitudinal direction, the first light guide including: (i) a lens surface facing the light source in a direction of the optical axis, (ii) a first light emission surface that is formed on the side opposite the lens surface in the direction of the optical axis of the light source, and (iii) a first reflecting surface configured to reflect a part of an incident light from the light source; and
a second light guide which has a connection end connected to a vehicle width direction outer side surface of the first light guide and extending outward in a vehicle width direction from the connection end, the second light guide including: (a) a second reflecting surface formed at a rear of the second light guide, and (b) a second light emission surface formed at a front of the second light guide, wherein
the first reflecting surface of the first light guide reflects the part of the incident light from the light source toward the connection end of the second light guide.

2. The vehicle lamp according to claim 1 , wherein the first reflecting surface is buried in the first light guide from the side end of the first light guide in the vehicle width direction.

3. The vehicle lamp according to claim 1 , wherein the second light guide is connected to a side surface of the first light guide on a side of the lens surface.

4. The vehicle lamp according to claim 1 , wherein the second light guide is connected to a side surface of the first light guide on a side of the first light emission surface.

5. The vehicle lamp according to claim 1 , wherein the second light guide is connected to a side surface of the first light guide that receives the reflected part of the incident light from the first reflecting surface of the first light guide.

6. The vehicle lamp according to claim 1 , wherein the second light guide extends outward from the vehicle width direction outer side surface of the first light guide in a direction that is opposite to a vehicle width direction inner surface on which the first reflecting surface is provided.

7. The vehicle lamp according to claim 1 , wherein the first reflecting surface is provided at an angle having one end on the first light emission surface of the first light guide and another end on the vehicle width direction inner surface of the first light guide.
