Head lamp

Abstract

Disclosed herein is a head lamp. The head lamp includes a light source emitting light, a reflection plate reflecting the emitted light toward a lens, and a shield integrally formed with the reflection plate to intercept a portion of the light illuminated toward the lens. The head lamp can accurately adjust an illumination pattern of light through a reduction of assembly tolerance between components.

       2. The head lamp according to  claim 1 , wherein the lens guide is provided with a collar jaw on which the shield is mounted, the collar jaw being formed with an insertion groove through which the shield is fitted into the collar jaw. 
     
     
       3. The head lamp according to  claim 1 , wherein the shield is formed with a through-hole through which a portion of light emitted from the light source passes, the through-hole being integrally formed with the reflection plate. 
     
     
       4. The head lamp according to  claim 3 , wherein the reflection plate has a seat-hole extending from the through-hole to define a passage of light and serving as a seat on which the light source is mounted, the seat-hole being formed with a coupling protrusion fitted into the light source. 
     
     
       5. The head lamp according to  claim 1 , further comprising:
 a heat sink connecting the light source, wherein the lens guide is provided with a mounting hole to which the heat sink is fastened. 
 
     
     
       6. The head lamp according to claim 1, wherein the light source, the reflection plate, and the shield are arranged such that at least a portion of light emitted from the light source passes through the shield without being reflected by the reflection plate.  
     
     
       7. The head lamp according to claim 1, wherein the light source comprises a light emitting diode configured to emit light both in an upward direction toward an upper reflection layer of the reflection plate and in a downward direction toward a lower reflection layer of the reflection plate.  
     
     
       8. The head lamp according to claim 1, wherein the shield and at least a portion of the reflection plate are receivable in the lens guide through the first opening.  
     
     
       9. An automotive lamp comprising:
 a light source emitting light;   a reflection plate reflecting the emitted light toward a lens;   a shield comprising a through-hole through which a portion of the light passes toward the lens; and   a lens guide having a first opening and a second opening provided at respective ends of the lens guide, the shield being received within and closing the first opening, and the lens being mounted at and closing the second opening.   
     
     
       10. The automotive lamp according to claim 9, wherein the lens guide is configured to house the shield and at least a part of the reflection plate.  
     
     
       11. The automotive lamp according to claim 9, wherein the shield is fixed to the reflection plate.  
     
     
       12. The automotive lamp according to claim 9, further comprising a heat sink connected to the light source, wherein the heat sink is mounted to the lens guide.  
     
     
       13. The automotive lamp according to claim 9, wherein the light source, the reflection plate, and the shield are arranged such that at least a portion of light emitted from the light source passes through the shield without being reflected by the reflection plate.  
     
     
       14. The automotive lamp according to claim 9, wherein the light source comprises a light emitting diode configured to emit light both in an upward direction toward an upper reflection layer of the reflection plate and in a downward direction toward a lower reflection layer of the reflection plate. 
     
     
       15. The automotive lamp according to claim 9, wherein the reflection plate comprises an inner reflection layer defining an internal passage through which light from the light source passes, wherein the cross-sectional area of the passage gradually decreases toward the light source.  
     
     
       16. An automotive lamp comprising:
 a light source comprising a light emitting diode configured to emit light;   a reflection plate comprising an upper reflection layer and a lower reflection layer, wherein the light emitted from the light emitting diode in an upward direction is reflected by the upper reflection layer toward a lens, and the light emitted from the light emitted diode in a downward direction is reflected by the lower reflection layer toward the lens;   a shield comprising a through-hole and disposed between the reflection plate and the lens, wherein the shield is configured to intercept a portion of the emitted light while permitting passage of the emitted light through the through-hole; and   a lens guide comprising a front part and a rear part and configured to hold the lens in the front part and the shield in the rear part, the lens guide having a first opening and a second opening provided at respective ends of the lens guide, the shield being received within and closing the first opening, and the lens being mounted at and closing the second opening.    
     
     
       17. The automotive lamp according to claim 16, wherein the shield is fixed to the reflection plate. 
     
     
       18. The automotive lamp according to claim 16, further comprising a heat sink connected to the light source, wherein the heat sink is mounted to the lens guide.  
     
     
       19. The automotive lamp according to claim 16, wherein the light source, the reflection plate, and the shield are arranged such that at least a portion of light emitted from the light source passes through the through-hole of the shield without being reflected by the reflection plate.  
     
     
       20. The automotive lamp according to claim 16, wherein the upper and lower reflection layers of the reflection plate define an internal passage through which the light from the light emitting diode passes, wherein the cross-sectional area of the passage gradually decreases toward the light source.  
     
     
       21. The automotive lamp according to claim 16, wherein the light emitting diode comprises a light emitting surface generally facing in a direction parallel to a longitudinal axis of an internal passage defined by the upper and lower reflection layers of the reflection plate.  
     
     
       22. The automotive lamp according to claim 16, wherein the rear part is configured to house the shield and at least a part of the reflection plate.
