Abstract
Description
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 which is compact and easy to manufacture.
Generally, a halogen lamp or a gas discharge lamp has been mainly used as a light source of a head lamp of a vehicle.
In the case of halogen lamps, the color temperature is about 3200K, which is slightly reddish, and the lifetime is within 1000 hours.
Compared to this, the color temperature of the gas discharge lamp is about 4300K, which is close to white, and it is used in high-end vehicles even though it is expensive due to its long life.
On the other hand, the white light emitting diode (LED) has a color temperature of about 5500K, which is close to the sunlight, and it is attracting attention as a head lamp light source in recent years because it minimizes fatigue in a human eye.
In addition, by minimizing the size of the LED, it not only improves the design freedom of the lamp, but also has economical efficiency due to a semi-permanent lifetime.
Recently, a variety of function lamps are installed. In the fog lamp, a fog lamp is provided to allow a driver or a pedestrian of another vehicle to check the position of the vehicle in a foggy weather, or a fog lamp that allows a driver or a pedestrian And DRL (Daytime Running Lamp) to prevent traffic accidents by making it easy to recognize the vehicle.
The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.
Since the vehicle lamp according to the prior art uses a bulb as a light source, a reflector having a reflecting surface of a certain size or more is required, and the angle of view of the light reflected forward by the reflector and the heat resistance inside the reflector, There is a problem that it is difficult to reduce the size.
Therefore, there is a need for improvement.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle lamp which is compact and easy to manufacture.
According to an aspect of the present invention, there is provided a light source device comprising: a light source for emitting light; A reflector for forwardly reflecting the light emitted from the light source; And a light guide inserted in the reflector, the light guide being formed with concave and convex portions to guide the light emitted from the light source forward.
Further, the reflector of the present invention is provided with an insertion groove portion to which the light source is coupled.
In the light guide of the present invention, an optical sheet is provided on a surface facing the concavo-convex portion.
Further, the present invention provides a lamp for a vehicle, wherein a bezel is provided to closely contact the optical sheet with the light guide.
The lamp for a vehicle according to the present invention is provided with a light guide for guiding light emitted from a light source forward and an LED for emitting heat backward is used as a light source so that a separate space is not required inside the lamp, There is an advantage that moisture can be prevented from being generated in the internal space.
Hereinafter, an embodiment of a vehicle lamp according to the present invention will be described with reference to the accompanying drawings.
In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation.
In addition, the terms described below are terms defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator.
Therefore, definitions of these terms should be made based on the contents throughout this specification.
FIG. 1 is an exploded perspective view illustrating a vehicle lamp according to an embodiment of the present invention, FIG. 2 is a sectional view illustrating a vehicle lamp according to an embodiment of the present invention, and FIG. 3 is a cross- FIG. 4 is a state diagram showing a vehicle lamp according to an embodiment of the present invention.

This makes it possible to provide a vehicle lamp that is downsized and easy to manufacture.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. .
Further, although a vehicle lamp has been described as an example, this is merely an example, and the lamp of the present invention can be used in products other than a vehicle.
Accordingly, the true scope of the present invention should be determined by the following claims.
1 is an exploded perspective view showing a lamp for a vehicle according to an embodiment of the present invention.
2 is a cross-sectional view illustrating a lamp for a vehicle according to an embodiment of the present invention.
3 is a perspective view illustrating a light guide of a vehicle lamp according to an embodiment of the present invention.
4 is a use state diagram showing a vehicle lamp according to an embodiment of the present invention.
