Problems solved by technology

[0012] However, since a headlamp for a vehicle in the related art uses a plurality of light sources and a shroud including a plurality of protrusions having different lengths and shapes in order to realize different modes of light, the change in the beam mode becomes variable. It is complicated and increases the manufacturing cost of the headlight

Abstract

A beam pattern changing structure for a head lamp is provided, which includes a light source provided in the head lamp to emit light, a reflector provided in the head lamp to reflect the light irradiated through the light source, a shield provided in front of the reflector, and an actuator mounted on the shield to make the shield rotatable. Accordingly, since low beams, high beams, and diverse beam pattern regions in the beam pattern changing stages are all implemented through one light source, the driver's visibility can be maximally secured and the glare of the opposite vehicle can be prevented. Further, the designs of the head lamps for the high beams and the low beams are the same, and thus the merchantability is increased.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2010-0123068 filed on December 3, 2010, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a beam pattern changing structure for a headlamp, and more particularly, the present invention relates to a beam pattern changing structure for a headlamp capable of utilizing reflection of a rotating shield Different beam patterns can be achieved without the need for additional light sources for illumination. Background technique [0004] Conventionally, halogen lamps or gas discharge lamps have been mainly used as light sources of vehicle headlights. [0005] In the case of a halogen lamp, its color temperature is approximately 3200K (which approximately corresponds to a red color series), and its maximum lifetime is within 1000 hours, posing a problem...
