Beam pattern changing sturcture of head lamp

摘要

PURPOSE: A beam pattern changing structure of a head lamp is provided to improve a lighting design using the reflection surface of a rotary shield. CONSTITUTION: A beam pattern changing structure of a head lamp comprises a light source(10), a reflector(20), a shield(100), and an actuator(200). The light source emits light. The reflector reflects the emitted light. The shield is formed on the front of the reflector. The actuator is installed on the shield and rotates the shield. The actuator is composed of a motor unit(210) and a gear stick(220). The motor unit is formed under the shield. One side of the gear stick is connected to the motor unit, and the other side is connected to the shield.
