Abstract

Disclosed is a bi function LED head lamp using a thin shield. The lamp includes: a low beam light source and a high beam light source installed at inner upper and lower sides of a reflector; a shield installed at a front end of the partition in the reflector; a lens holder in which the rear is joined to a front surface of the reflector; and a signal reflection surface installed at an inner lower end of the lens holder. The low beam and the high beam are implemented only by turning on and off an LED through applying the thin shield without an actuator.

First claim

What is claimed is:

1. A bi function LED head lamp using a thin shield, comprising:
a reflector in which a front inlet is opened and an inner space is partitioned into an upper low beam reflector space and a lower high beam reflector space by a partition installed at the center;
a low beam light source installed at a top inner side of the partition so as to be positioned in the upper low beam reflector space;
a high beam light source installed at a bottom inner side of the partition so as to be positioned in the lower high beam reflector space;
a shield installed at a front end of the partition;
a lens holder in which a lens is mounted on the front and the rear side is joined to a front surface of the reflector; and
a signal reflection surface installed at a lower inner end of the lens holder.

2. The lamp of claim 1 , wherein the low beam light source and the high beam light source are LED light sources.

3. The lamp of claim 1 , wherein the shield is the thin shield and a hole through which the light source passes is bored at the front end of the shield.

4. The lamp of claim 3 , wherein the hole has a semicircular shape.

5. The lamp of claim 1 , wherein the signal reflection surface is formed integrally with the lens holder.

6. The lamp of claim 5 , wherein an upper front surface of the signal reflection surface faces the lens and is formed by an inclined surface that is inclined back upward from the side view.

7. The lamp of claim 5 , wherein both surfaces of the upper front surface and an upper rear surface of the signal reflection surface are formed by inclined surfaces of which the widths decrease upward from the side view.
