Description

Automotive Head Lamps {Automotive head lamp}

The present invention relates to a head lamp of a vehicle, and more particularly, to a vehicle head lamp capable of irradiating light of different beam patterns and improving heat dissipation efficiency while securing a sufficient amount of light through a simple structure.

Generally, a vehicle is equipped with a variety of vehicle lamps having a lighting function and a signal function for notifying other vehicle users or other road users of the traveling state of the vehicle so that an object located in the vicinity of the vehicle can be easily identified at night when traveling . For example, headlights and fog lights are aimed at lighting functions, and turn signal lights, taillights, brake lights, side markers and the like are intended for signal functions.

Such automotive lamps have typically used light sources such as halogen lamps or high intensity discharge (HID) lamps.

Recently, a light emitting diode has been used as a light source. The light emitting diode has a color temperature of about 5500K, which is close to solar light, which minimizes fatigue in a human eye and minimizes the size thereof, In addition, it has economical efficiency due to its semi-permanent lifetime.

Attempts have been made to overcome the increase in the conventional complex lamp configuration and fabrication steps by introducing light emitting diodes and there is a tendency to overcome the space problem of the lamp due to the extension of the lamp life and the small size due to the characteristics of the light emitting diode itself .

The lamp module with the light emitting diode as a light source is arranged in different directions with respect to the optical axis of the head lamp, and the remaining components are configured to be common so that the light of various beam patterns can be irradiated while minimizing the required space. There is.

In addition, a plurality of lamp modules arranged in a predetermined direction with respect to the optical axis of the head lamp may be configured to secure a sufficient amount of light.
