Abstract

The present invention provides a vehicle lamp, particularly a projector-type vehicle lamp which may enhance visibility of a pedestrian at the roadside without giving a glare to a driver of an oncoming vehicle or a preceding vehicle. The vehicle lamp includes: a mirror member (20) which has an upward reflecting surface (20a) that upwardly reflects a part of the light reflected from a reflector (16). A front edge (22) of the upward reflecting surface passes through a rear focus (F) of a projection lens (12). A central portion (22C) of a front edge (22) of the upward reflecting surface (20a) is formed to extend along a meridional image surface (M) of the projection lens (12), and left and right end portions (22L and 22R) of the front edge are formed to be displaced forward from the meridional image surface (M). Accordingly, a central portion of a cut-off line of a low-beam light distribution pattern is formed to be clear and left and right end portions of the cut-off line become blurred such that light may be irradiated to a space in the upper vicinity of the left end portion and / or the right end portion.

Description

technical field [0001] The present invention relates to a spotlight type vehicle lamp, in particular to a spotlight type vehicle lamp provided with a reflective member. Background technique [0002] Generally, in a spotlight type vehicle lamp, light from a light source arranged behind the rear focus of the projection lens is reflected toward the projection lens by the reflector. [0003] And, when forming a light distribution pattern having a cut-off line at an upper end such as a low beam light distribution pattern with such a vehicle lamp, a shield provided with a shielding member for shielding part of the reflected light from the reflector is often used. structure. [0004] In this case, for example, as described in Patent Document 1, in a spotlight type vehicle lamp using a light emitting element or the like as a light source, it is configured to have a direction for reflecting part of the reflected light from the reflector upward. The reflective member on the upper re...
