Abstract

A vehicle lamp includes a lamp outer case, a reflection-type first lamp unit, a direct emission-type second lamp unit, and a compound lens. The lamp outer case includes a cover and a lamp housing. The first lamp unit has a first light source, a reflector and a shade and forms a collective optical system. The second lamp unit has a second light source, which directly emits light, and forms a defuse optical system. The compound lens is disposed along an inner surface of the cover, and has an outer surface facing the inner surface of the cover that is formed as a curved light emitting surface. The cover also includes first and second control portions. The light emitting surface has a shape which is displaced to the rear as it extends transversely outwards of a vehicle.

First claim

What is claimed is:

1. A vehicle lamp comprising:
a lamp outer case comprising:
a cover, and
a lamp housing;

a reflection first lamp unit comprising:
a first light source,
a reflector which reflects light emitted from the first light source, and
a shade which cuts off part of light emitted from the first light source and forming a collective optical system;

a direct emission second lamp unit having a second light source, which directly emits shining light,
wherein the second lamp unit is disposed on an external side, in a transverse direction of the vehicle, of the first lamp unit and forms a diffuse optical system; and

a compound lens disposed along an inner surface of the cover,
wherein an outer surface of the compound lens facing the inner surface of the cover is formed as a light emitting surface and is formed into a curved surface,
wherein a first control portion and a second control portion are provided on an inner surface of the compound lens,
wherein the inner surface of the compound lens faces the first lamp unit and the second lamp unit so that the first control portion and the second control portion control light emitted from the first light source and light emitted from the second light source, respectively, and
wherein the light emitting surface of the compound lens is formed into a shape which is displaced to the rear as the compound lens extends outwards in the transverse direction of the vehicle.

2. The vehicle lamp of claim 1 , further comprising a third lamp unit having a different function from those of the first lamp unit and the second lamp unit, the third lamp unit disposed on an external side of the second lamp unit.

3. The vehicle lamp of claim 2 , wherein a third control portion is provided on the compound lens for controlling light emitted from the third lamp unit.

4. The vehicle lamp of claim 1 , wherein all light from the second lamp unit is directly incident on the compound lens without being reflected.

5. The vehicle lamp of claim 1 , wherein the shade of the reflection first lamp unit is a movable shade.

6. The vehicle lamp of claim 5 , wherein a reflecting surface is formed on an upper surface of the shade.

7. The vehicle lamp of claim 1 , further comprising:
an integrated heat dissipation member to which the first and second lamp units are attached.

8. The vehicle lamp of claim 7 , wherein the compound lens is disposed between the cover and the integrated heat dissipation member.

9. The vehicle of claim 1 ,
wherein the second control portion has a convex surface directed to the second lamp unit, and
wherein the convex surface of the second control portion faces the second lamp unit.
