Abstract

The utility model discloses a meeting lighting lamp for motor vehicle running at night, which is principally characterized in that a polarizing coating whose polarizing shaft has a fixed direction is installed in front of the lamp. A driver observes front road surface through a polarizing light observation mirror whose polarizing shaft is identical to the polarizing shaft of the light of the vehicle, and a remote bright visual sensation can be obtained. The polarizing light illuminated by opposite lamps of the vehicle, whose direction is just perpendicular to the polarizing shaft of the observation mirror of the driver, can not penetrate the observation mirror and disturb the sight of the driver. The improved lighting lamp reserves all the structures of the primary lamp, and manufacturing cost doesn't obviously increase.

Description

Polarized head light for automobile

The utility model belongs to the car lighting technical field of lamps, says so exactly to the improvement of headlight for motor-driven vehicles tool.

During power actuated vehicle night running meeting, generally be to close headlight or conversion lower beam illumination, the vehicle front distance of distinct vision is very near, and moving velocity is forced to slow down.

The purpose of this utility model is, a kind of novel polarized light train crossing jacklight is provided, its light neither influences opposite vehicle driver vision, can make road surface, the place ahead that the higher brightness and the distance of distinct vision far away are arranged again, helps keeping Vehicle Speed and tries to forestall traffic accidents.

The design will have that headlight for motor-driven vehicles glass disposes that a slice polarization axis direction is fixed now, polarization axle and horizontal sextant angle are 45 ° polarizing coating, can become the polarized light train crossing jacklight, chaufeur sees through the polarizing coating parameter polarized light sight glass identical with the lamp upper diaphragm, can see road surface, the place ahead situation clearly, and not be subjected to the influence of opposite car light.

Contrast accompanying drawing below, this solution further specified:

Accompanying drawing 1 is the constructional drawing of polarized light passing lamp.(1) is housing among the figure; (2), (3) are reflectors; (4) be bulb; (5), (6) are lamp glasss; (7) be polarizing coating, its polarization axle and horizontal sextant angle are 45 ° ± 1 °.Accompanying drawing 2 is principle schematic.This car light polarized light direction of polarization is identical with the polarization axis direction of chaufeur polarized light sight glass, and chaufeur produces bright vision to the light of institute's steering vehicle; Because opposite car light polarized light direction of polarization is vertical with driver's observation mirror polarization axis direction, thus can not see through sight glass, so the chaufeur vision is not had any obstruction.

Claims

1, a kind of power actuated vehicle night running train crossing jacklight, it comprises housing (1), reflector (2), (3), bulb (4) and lamp glass (5), (6).It is characterized in that, polarizing coating (7) is housed before the bulb, the diaphragm polarization axle is that direction is fixed, and polarization axle and horizontal sextant angle are 45 ° ± 1 °.
