Embodiment Construction

[0026] Next, preferred embodiments for implementing the vehicle headlamp of the present invention will be described with reference to the drawings.

[0027] The vehicular headlamp 1 is mounted on both left and right ends of the front end of the vehicle body.

[0028] like figure 1 As shown, the vehicle headlamp 1 is constituted such that, for example, the inside of a lamp housing 4 composed of a lamp body 2 with an open front and a cover 3 mounted on the front end of the lamp body 2 is formed as a lamp chamber 5, and the lamp chamber 5 is arranged There are lamp units 6 .

[0029] In the lamp house 5 , the holding member 7 is arranged to be freely inclined in the left-right direction and the front-rear direction via the optical axis adjustment mechanism 8 .

[0030] The holding member 7 is formed of a metal material with high thermal conductivity, and has a base portion 9 facing in the front-rear direction.

[0031] The upper and lower ends of the base part 9 are provided w...

Abstract

A vehicle headlight that prevents dazzling light for pedestrians on the basis of ensuring improved visibility of the driver. This vehicle headlamp has a light source body and a projection lens. The light source body has a plurality of semiconductor light-emitting elements arranged in a left-right direction and a lower reflector that reflects light emitted from the semiconductor light-emitting elements and is arranged below the semiconductor light-emitting elements. , the projection lens projects and irradiates the light emitted from the semiconductor light-emitting element, and the upper pattern in the light distribution pattern of the high beam that irradiates the long-distance area is formed by the light reflected by the lower reflector and irradiated from the projection lens, controlling the light emitted from the semiconductor The incident state of the light emitted from the element and incident on the lower reflector changes the formation state of the upper pattern in the light distribution pattern of the high beam. Since the light distribution pattern of the high beam is controlled so that light does not irradiate the upper side of a pedestrian, it is possible to prevent dazzling light for pedestrians while ensuring improved visibility for the driver.

Description

technical field [0001] The invention relates to a vehicle headlamp. Specifically, by controlling the incident state of the light emitted from the light source and entering the lower reflector, the formation state of the upper pattern in the light distribution pattern of the high beam is changed, thereby preventing the Creates a blinding light on walkers. Background technique [0002] On the vehicle headlamp, a plurality of light sources are arranged inside the lamp housing formed by the cover and the lamp body, some light sources are used as light sources for irradiating low beams, and other light sources are used as light sources for irradiating high beams (for example, refer to Patent Document 1). As a light source for illuminating high beams, many semiconductor light-emitting elements, such as light-emitting diodes (LED:LightEmittingDiode), are being used. [0003] In the vehicle headlamp described in Patent Document 1, among the light sources for irradiating the high ...
