Abstract

A head lamp in a vehicle may include a light source for emitting a light, a reflector for reflecting the light forward from the light source, a lens for transmitting the light being forwarded toward a front from the light source and the reflector, a holder having one end coupled to the lens and the other end coupled to the reflector to make the lens spaced at a predetermined distance from the reflector, and a movable shield disposed between the light source and the reflector and the lens for selectively shielding a portion of the light being forwarded toward the lens from the light source and the reflector, or not shielding the portion of the light being forwarded toward the lens from the light source and the reflector when being moved to create a space between the movable shield and a lower end of the holder to allow the light pass through.

First claim

What is claimed is:

1. A head lamp in a vehicle comprising:
a light source for emitting a light;
a reflector for reflecting the light forward from the light source;
a lens for transmitting the light being forwarded toward a front from the light source and the reflector;
a holder having one end coupled to the lens and the other end coupled to the reflector to make the lens spaced at a predetermined distance from the reflector; and
a movable shield disposed between the light source and the reflector and the lens for selectively shielding a portion of the light being forwarded toward the lens from the light source and the reflector, or not shielding the portion of the light being forwarded toward the lens from the light source and the reflector when being moved to create a space between the movable shield and a lower end of the holder to allow the light pass through,
wherein the movable shield shields the portion of the light being forwarded toward the lens with a first side of the movable shield, and
wherein the light emitted between the movable shield and the lower end of the holder from the light source when the movable shield is moved is configured to be reflected at a second side of the movable shield and directed to the front of the head lamp through the space formed between the movable shield and the lower end of the holder.

2. The head lamp in a vehicle of claim 1 , wherein the light reflected at the second side of the movable shield and directed to the front produces a high beam.

3. The head lamp in a vehicle of claim 1 , wherein the movable shield is hinge coupled to the holder and movable by a hinge motion.

4. The head lamp in a vehicle of claim 3 , further comprising:
a solenoid connected to the movable shield for moving the movable shield upon having power supplied thereto.

5. The head lamp in a vehicle of claim 1 , further comprising:
a fixed shield provided between the movable shield and the lens and having a first side for shielding the portion of the light being forwarded toward the lens from the light source and the reflector and a second side for absorbing lights reflected and scattered by an inside surface of the holder and by an inside surface of the lens.

6. The head lamp in a vehicle of claim 5 , wherein the movable shield is hinge coupled to the fixed shield and movable by a hinge motion.

7. The head lamp in a vehicle of claim 6 , further comprising:
a solenoid coupled to the fixed shield connected to the movable shield for moving the movable shield upon having power supplied thereto.

8. The head lamp in a vehicle of claim 7 , further comprising:
an elastic member provided to a portion at which the movable shield and the fixed shield are hinge coupled for returning the movable shield to an original position if power supply to the solenoid is cut off.

9. The head lamp in a vehicle of claim 7 , wherein the reflector has a stopper formed thereon for being brought into contact with the moving movable shield for preventing the hinge motion of the movable shield from progressing excessively by the solenoid.

10. The head lamp in a vehicle of claim 9 , wherein the stopper is formed to prevent impact of contact with the movable shield.

11. The head lamp in a vehicle of claim 8 , further comprising:
a buffer portion formed at a portion the fixed shield is to be brought into contact with the movable shield for preventing an impact of contact with the fixed shield when the movable shield returns to the original position by the hinge motion owing to the elastic member.
