Abstract

A head lamp unit for vehicle includes a head lamp and a position lamp housed in a housing, in which a cover lens is mounted on the front surface of a lamp body. A position lamp emitter is arranged to be hidden by a head lamp reflector, seen from the front. A position lamp reflection surface reflecting a light emitted from the position lamp emitter to guide the light to the front of the housing is provided around the head lamp reflector.

First claim

What is claimed is:

1. A head lamp unit for a vehicle comprising:
a housing;
a head lamp emitter housed in the housing;
a head lamp reflector housed in the housing;
a position lamp emitter housed in the housing and hidden by the head lamp reflector when viewed from a front of the housing, the head lamp reflector having a mirror-finished back surface configured to reflect in a rearward direction forward-traveling light emitted from the position lamp emitter; and
a position lamp reflection surface arranged around the head lamp reflector and being separate from the head lamp reflector, the position lamp reflection surface being configured to reflect light received directly from the position lamp emitter toward the front of the housing, and to reflect light reflected from the mirror-finished back surface of the head lamp reflector toward the front of the housing.

2. The head lamp unit for a vehicle according to claim 1 , wherein the position lamp reflection surface comprises a first reflection surface and a second reflection surface, the second reflection surface being adjacent to an outward edge of the first reflection surface in both the left direction and the right direction.

3. The head lamp unit for a vehicle according to claim 1 , wherein the position lamp reflection surface comprises a first reflection surface and a second reflection surface, the second reflection surface being arranged outside the first reflection surface in the vehicle width direction and extending in the vertical direction.

4. The head lamp unit for a vehicle according to claim 1 , wherein the mirror-finished back surface of the head lamp reflector comprises a visor of the position lamp emitter.

5. The head lamp unit for a vehicle according to claim 1 , wherein folded portions are formed at outer peripheral ends of the left upper end and the right upper end of the head lamp reflector, the folded portions being configured to hide the position lamp emitter from being viewed from the front and from the top.

6. The head lamp unit for a vehicle according to claim 1 , wherein the housing includes a lamp body and a cover lens mounted on a front surface of the lamp body, and the position lamp emitter is secured to the lamp body.

7. The head lamp unit for a vehicle according to claim 1 , further comprising a design cover arranged in the housing and configured to cover a periphery of the head lamp reflector from the front of the housing, the design cover being having the position lamp reflection surface thereon.

8. The head lamp unit for a vehicle according to claim 1 , wherein the head lamp emitter is a left head lamp emitter, the head lamp unit further comprising a right head lamp emitter housed in the housing, the position lamp emitter being a left position lamp emitter, the head lamp unit further comprising a right position lamp emitter housed in the housing, the left position lamp emitter and right position lamp emitter being arranged behind the left end of the head lamp reflector and the right end of the head lamp reflector, respectively.

9. The head lamp unit for a vehicle according to claim 1 ,
wherein the position lamp reflection surface comprises:
a first reflection surface having a concave surface shape and configured to cover the position lamp emitter from the rear so as to guide a reflected light toward the front of the housing; and
a second reflection surface extending from a position adjacent to the first reflection surface, and configured to redirect a reflected light from the first reflection surface around the head lamp reflector so as to guide the reflected light inward with respect to a width of the head lamp reflector when viewed from the front of the housing.
