Problems solved by technology

Therefore, among the cut-off lines of the light distribution pattern for expressway formed by the edges (ェッジ) of the movable shade, the cut-off line of the portion blocked by the servo fixed shade is not clear in the conventional vehicle headlamp. Or, in the light distribution pattern for highways, the light of the part blocked by the servo fixed shade is largely cut off.

Embodiment

[0027] Hereinafter, the configuration of the vehicle headlamp of the present embodiment will be described. The vehicle headlamp of this embodiment is used for left-hand traffic in Japan. The vehicle headlight used for left-hand traffic in Europe also has almost the same configuration as the vehicle headlight of this embodiment. In addition, the vehicle headlamps used for right-hand traffic in Europe and for right-hand traffic in North America have a structure in which the left and right sides of the vehicle headlamp of this embodiment are reversed.

[0028] figure 1 In , reference numeral 1 is the vehicle headlamp of this embodiment. The above-mentioned vehicle headlamp 1 is provided on the left and right sides of the front of an automobile (vehicle), for example, a projection type headlamp. In addition, the above vehicle headlamp 1 such as figure 1 As shown, it includes a light source 2, a reflector 3, a projection lens (converging lens, convex lens) 4, a light shielding ...

Abstract

The invention relates to a head lamp for vehicle. In the existing head lamp of the vehicle, the portion shielded by a servo fixing shading parts is not clear in the cutoff line of the light distribution pattern, or the light of the portion shielded by the servo fixing shading parts is greatly eliminated in the light distribution pattern. The arris of the cutoff line CL of the light distribution pattern LP for vehicle is set on the shading parts. The arris has a first arris (17) in or adjacent to the focus F3 of the projector lens (4) and a second arris (18) closer to one side of the projectorlens (4) than the first arris (17). A shading part (22) is set on the second arris (18) for reducing the luminosity of preset part in the light distribution pattern LP for vehicle. The invention can obtain clear cutoff line CL and the light distribution pattern LP for vehicle with reduced luminosity at preset part.

Description

technical field [0001] The present invention relates to a projection-type vehicle headlamp, which is a projection-type vehicle headlamp for irradiating a light distribution pattern having a cutoff line, for example, a light distribution pattern for passing vehicles, to the front of a vehicle. Background technique [0002] There has long been a projection type vehicle headlamp that irradiates a light distribution pattern having a cutoff line to the front of the vehicle (for example, refer to Patent Document 1: Japanese Unexamined Patent Publication No. 2005-93182). Hereinafter, a conventional vehicle headlamp will be described. Conventional vehicle headlamps include a light source, a movable shade, and a servo-fixed shade. [0003] Hereinafter, the operation of the conventional vehicle headlamp will be described. In conventional vehicle headlamps, when the movable shade is switched to the low beam position, the light source is turned on to obtain a light distribution patter...
