Description

[0001] Vehicle lamp and method for manufacturing same [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp for a vehicle, and more particularly to a lamp for a vehicle installed in front of a vehicle and including a shield.

Background Art [0002] A headlamp for a vehicle is roughly divided into a headlamp installed in front of the vehicle and a taillamp installed in the rear of the vehicle. Generally, a headlamp is mounted on both sides of a front side of a vehicle to secure a view direction of the driver in the nighttime driving. Such a headlamp may include a shield for blocking a part of the irradiated light. Shields are used to implement regulated light distribution. Or the operation may cause the headlamp to be switched to a low beam or a high beam.

1 is a view showing a head lamp for a vehicle including a shield. Referring to Fig. 1, a typical headlamp for a vehicle is provided with a reflector 1 and a shield 2 in front of the reflector 1. A lens holder 3 may be provided in front of the shield 2 and a lens mounting rim 4 may be provided between the lens 5 and the lens holder 3.

At this time, in manufacturing the headlamp for a vehicle, the reflector 1, the shield 2, and the lens holder 3 are separately manufactured and assembled together.

Here, the reflector 1 is subjected to a deposition process with aluminum or the like to form a reflective surface on the inner surface. However, due to the structure of the concave reflector 1, there is a problem that deposition is not uniformly carried out to the inside of the inner surface. Thus, in manufacturing the reflector 1, there is a risk that a part of the inside of the inner surface of the reflector 1 is not vapor-deposited.

In the production of the shield 2, in the case of the shield 2 forming the cut-off boundary line, it is typical that the shield 2 is manufactured in a plate shape through press working. Because of. Deformation may occur in the shield 2 during press working. Further, there is a high risk that deformation occurs during assembly process with the lens holder 3 or the reflector 1 due to the structural characteristics of the shield 2 formed of a plate shape.

On the other hand, when the reflector 1, the shield 2, and the lens holder 3 are combined, there is a problem that the optical performance of the headlamp may be adversely affected due to the generated tolerances. Particularly, as described above, when the shield 2 is deformed, a large cumulative tolerance can be caused. In addition, when the non-deposition area is formed inside the inner surface of the reflector 1, There is a problem.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a vehicle lamp capable of improving the optical performance by eliminating the cumulative tolerance caused by the combination of the reflector 1, the shield 2 and the lens holder 3 For that purpose.

According to another aspect of the present invention, there is provided a light emitting device comprising: a light source; a reflector that reflects light emitted from the light source; a shield portion disposed in front of the light source to block a part of light emitted from the light source and the reflector; And a lens holder for fixing a lens disposed in front of the shield portion, the method comprising the steps of: a) molding at least a part of at least two of the reflector, the shield portion and the lens holder into one unit as an upper module, B) forming a reflector of the upper module and a reflector of the lower module and post-processing the shield part; And c) combining the upper module and the lower module. .

Preferably, in the method of manufacturing a lamp for a vehicle, the upper module is molded into a part of the reflector, and the lower module is integrally formed with another part of the reflector, the shield part and the lens holder.

Preferably, in the method of manufacturing a lamp for a vehicle, the upper module is formed such that a part of the reflector and a part of the lens holder are integrally formed, and the lower module includes a part of the reflector and the shield part and the lens holder And another part may be integrally formed.

Preferably, when the reflector is divided into an upper portion and a lower portion, the reflector portion corresponds to the upper portion, and the other portion of the reflector corresponds to the lower portion.
