Description

Lamp for vehicle

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 that can improve appearance through a simple configuration.

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, head lamps and fog lamps are mainly intended for lighting functions, and turn signal lamps, tail lamps, and brake lamps are mainly used for signal functions.

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

Automotive lamps are considered to be very important in the appearance of the vehicle in addition to lighting and signal functions. Particularly, in the case of a head lamp or a tail lamp, it becomes an important factor for determining the appearance of the vehicle at night.

Therefore, vehicle lamps have a fundamental role in securing the driver's visibility, not only in terms of functional aspects to help safe driving, but also in terms of the aesthetics of the consumer through the design improvement, which also has a great influence on whether or not to purchase the vehicle.

Therefore, there is a need for a method of enhancing an aesthetic effect by giving a visual pattern that is improved by design rather than just a static image through simple lighting.
