Abstract
The utility model discloses an anti-dazzle device for automobiles meeting at night. With the principle of optical polarization utilized, two polarizers are mutually perpendicular to each other to prevent light from passing in order that the glare of the vehicle lamps of opposite party is repressed, and synchronously the road surface illuminated by the vehicle lamps of self and the opposite party can also be clearly observed, without the vehicle lamps intermittently switched on and with meeting accidents reduced, and in addition, a pedestrian and a bicycle rider pulling on polarizing glasses can also effectively avoid the glaring of the head lamp of the vehicle of the opposite party.
Description
The utility model relates to a kind of power actuated vehicle lighting source that improves, and particularly a kind ofly can make the driver avoid the other side's car light niphablepsia, sees road clearly.
The lighting headlight that is equipped with on the existing power actuated vehicle, at night during mutual meeting, often must intermittently play lamp because of the other side's light is dazzling, be difficult for seeing clearly road, the driver is also made troubles, do not turn off the light as the other side driver, or when intermittently mutually playing lamp, target etc. is broken in half road suddenly, and this process often gets into an accident easily.The automatic intermittently lamp-enlightened device of existing meeting, though can alleviate driver's burden, above problem still can not solve, and cost is also high, is difficult for installing, reliability can't be determined during work.
The purpose of this utility model is that a kind of new vehicle lighting source and corollary apparatus will be provided, and can suppress the other side's car light blaze effectively, sees clearly from the road surface of side and the other side's car light irradiation, realizes being not related to the lantern festival car.
The utility model is achieved in that and utilizes the polarisation of light principle.Adopt two palarizers, a slice is placed on Vehicular lamp previous crops polarizer, and it is analyzer that another sheet is placed on the other side driver's eyes previous crops, when two polaroid polarization direction angles are 90 ° when spending, be quadrature, the light intensity minimum that driver observation arrives plays the other side's high light effect that suppresses.
By Malus' law: intensity is the polarized light of I, see through analyzer after, transmission light intensity (not considering to absorb) is I=I
0COS
2A.
A is the angle between polarizer and two polarization directions of analyzer in the formula.
Though self car light and the other side's car light inclined to one sideization are radiated on the road surface, produce reflected light, scattering light has changed polarization direction, so can be observed.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
1, fixing with extraordinary lamp (making lamp glass with polarizer) illumination, driver oneself wears to paste on polarising glass or the Windshield shifting board that polarized material is done is installed in polarization film or the operator's compartment.
Fig. 1 is a car headlight structure sketch, and lamp lens adopts polarized glass to make 2, and we can unify to stipulate to select for use horizontal direction polarization direction.Fig. 3 is a polarising glass, Fig. 4 is the polarization film 6 on the Windshield, drives indoor activity polarization baffle plate 8, and above polarization direction is all elected vertical direction 5 as, if the unification of Fig. 2 polarization direction is chosen as vertical direction, Fig. 3, Fig. 4, Fig. 5 are horizontal direction so.
This covering device main body has: car light lamp body 1, and polarization lamp glass 2, supporting with it polarising glass is made up of the polaroid 4 of mirror holder 3, two identical polarization directions, also has the polarization film 6 on the Windshield, and Windshield 7 is driven indoor activity polarization baffle plate 8.
The advantage of this device: simple and convenient, on the road pedestrian, people by bike put on polarising glass also can be anti-dazzle.Shortcoming: light loss is arranged.
2, use with common car light is parallel, when meeting, use extraordinary headlight, use common headlight during driving, control by switch.
This covering device main body has: common car light 9 among Fig. 6, extraordinary car light 10, car light change-over swith 11 among Fig. 7, polarization baffle plate 12.Fig. 8 headlight change-over circuit schematic diagram.Common car light 13 among the figure, extraordinary car light 14, former lighting switch K
1, car light change-over swith K
2
By Fig. 7, Fig. 8, polarization baffle plate and car light change-over swith interlock put down baffle plate, K switch during meeting
2Extraordinary car light is connected in work, and extraordinary car light is bright, and common headlight goes out, and meeting finishes, and carries on baffle plate K
2Again connect with common car light, extraordinary car light goes out, and common car light is bright.
The advantage of this covering device: overcome the optical energy loss in the driving, operated also comparatively easy.Shortcoming: compare repacking with last kind complicated, and pedestrian on the road, people by bike put on polarising glass not necessarily works.
More than two covering devices all can adopt in practice.
Claims (2)
1, a kind of power actuated vehicle nighttime meeting anti-dazzle device that is used for is characterized in that it is by extraordinary car light 10 with polarized glass 2 and supporting with it glasses with polaroid 3 or be attached to the polarization film 6 on the windshield or the movable polarization baffle plate 8 that is installed in the operator's compartment is formed.
2, a kind of motor-driven vehicle meeting at night anti-dazzle device that is used for is characterized in that it is to have polarized glass 2 extraordinary car lights 10 and be installed in the operator's compartment to form with the polarization baffle plate 12 of car light change-over swith 11 interlocks control.
