Description

Vehicle lamp {Lamp for vehicle}

The present invention relates to a vehicle lamp, and more particularly, to a vehicle lamp capable of forming various beam patterns while simplifying the configuration.

In general, a vehicle is provided with various types of vehicle lamps having a lighting function for easily checking an object located around the vehicle during night driving and a signal function for informing the other vehicle or road users of the vehicle's driving status.

For example, head lamps and fog lamps are mainly intended for lighting functions, and daytime running lamps, turn signal lamps, tail lamps, brake lamps, side markers, etc. are mainly intended for signal functions. In addition, in order to sufficiently exert each function of a vehicle lamp, the installation standards and standards are prescribed by law.

Recently, a light emitting diode is used as a light source, and the light emitting diode has a color temperature of about 5500K, which is close to sunlight, which minimizes human eye fatigue and minimizes size to increase the design freedom of the lamp. In addition, it is economical due to its semi-permanent life.

At the same time, attempts have been made to overcome the increase in the conventional complicated lamp construction and processing steps, and there is a trend to overcome the spatial problem of the lamp due to the small size and the long life of the lamp due to the characteristics of the light emitting diode itself. When light-emitting diodes are used, one or more light-emitting diodes may be used to secure a sufficient amount of light while irradiating light of each beam pattern.

On the other hand, the above-described various types of vehicle lamps are separately configured and installed so as to be able to irradiate light of a beam pattern according to its function.

For example, the components constituting the vehicle lamp may include a light source and a reflector, etc., each of which is provided with a light source and a reflector or the like according to the vehicle lamp, or form a plurality of beam patterns in one vehicle lamp such as a head lamp. When it is required, each component according to the beam pattern is provided.

However, when the above-described components of the vehicle lamp are separately installed according to the type or beam pattern of the vehicle lamp, there is a problem in that efficiency is reduced in terms of space utilization or cost due to an increase in installation space and cost.

Accordingly, there is a need for a method capable of forming various beam patterns while simplifying the configuration of a vehicle lamp.
