Title:
HEAD LAMP FOR VEHICLE
Document Type and Number:
Japanese Patent JP3967048
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a head lamp for a vehicle constructed to move a shade for beam change, allowing easy assembly of a beam changer into a lighting fixture.
SOLUTION: A beam changer 34 is provided for beam change between a low beam and a high beam with the rotational movement of a shade 32, capable of shading a portion of a light from a discharge emission portion 22a reflected from a reflecting plane 24a of a reflector 24, between two positions where the shading amounts are different in value. The beam changer 34 has a tensile coil spring 44 for elastically energizing the shade 32 to a position of construction of the low beam and a solenoid 42 for thrusting the shade 32 against the elastic energizing force of the tensile coil spring 44 and rotationally moving the shade 32 to a position of construction of the high beam. The solenoid 42 is constructed only to thrust the shade 32, not constructed to be connected to the shade via pins as usual, whereby the beam changer 34 can be assembled into a reflector unit 116 with the solenoid 42 and the tensile coil spring 44 simply arranged in position.
