Abstract

The utility model relates to a polarized light lighting lamp which is a lighting lamp designed by applying the polarized light technology to the lighting technology and improved on the existing vehicle lamp. A polarizing filter is arranged on the inner surface of the existing vehicle lamp shade in the way that the permeating and vibrating direction of the polarizing filter inclines at an included angle of 45 DEG from the vertical direction to the right direction of a driver (or the left direction of the driver), so that light emitted by all vehicle nocturnal lighting lamps is linearly polarized light seemingly in an included angle of 45 DEG and with a low left and a high right (from the driver's angle). The linearly polarized light is just in a 90 DEG angle with the permeating and vibrating direction of polarizing glasses worn by the opposing driver, which avoids the visual dizziness of opposing drivers to reduce the hidden peril of accidents for vehicles in nighttime running. The polarized light lighting lamp which belongs to the polarizing optics lighting field is suitable for lighting vehicles running at night and in tunnels, caves, etc.

Description

Polarized light lamp

Technical field:

Polarized light lamp is that polarized-light technique is applied on the lighting engineering and a kind of illuminating lamp of invention, and it is applicable to that motor vehicles use when night illumination and tunnel, cavern etc. locate to travel illumination.Belong to the polarization optics lighting field.

Background technology:

At present, when two motor vehicles travel night relatively, because the direct projection effect of the other side's car light makes the driver be difficult to see clearly road surface, the place ahead.Particularly when there is the pedestrian in the place ahead, often be difficult to find.The incidence of this type of traffic accident is very high.The reason that produces this phenomenon is that the scattered light of existing motor vehicle illuminating lamp is too strong, causes opposite personnel's vision dizzy.

The utility model content:

The utility model purpose is polarized-light technique is applied on the illuminating lamp, and reduction is dizzy because of the vision that beam divergence brings the opposite personnel, the hidden danger of traffic accident during with minimizing motor vehicles night running.

The purpose of this utility model is to realize like this.It is transformed existing motor vehicles car light.Polarizer is installed in the lampshade inner surface of existing Vehicular lamp, install polarizer make its shake thoroughly direction for from the vertical ground direction to driver's right direction (also can to driver's left direction) the 45 degree angles that tilt, the light that all motor vehicles night flight or navigation illuminating lamps are penetrated is the linearly polarized light of 45 degree angles for a left side low right high (from driver's angle).Simultaneously the driver on the car to wear the pair direction of shaking thoroughly also be that a left side is low right high, with the car light identical polarising glass of direction that shakes thoroughly.The direction of shaking thoroughly of the polarised light that makes own automobile lamp like this and sent is identical with the own direction of shaking thoroughly of being worn glasses, and light can the transmission glasses, make the driver see road conditions clearly.But, because the other side's vehicle traveling direction is opposite, the polarization direction of the light that shakes thoroughly that our car light irradiation goes out for the driver on opposite and related personnel (as traffic-police, the pedestrian), be that a left side is high right low, just in time be an angle of 90 degrees with the direction of shaking thoroughly of its polarising glass of wearing, make the other side personnel see that the brightness of our vehicle light illumination is minimum (calculating the one thousandth of having only former intensity of light by extinction ratio), it is dizzy to make the other side personnel no longer produce light like this, can more clearly see our road conditions and driving situation clearly, thereby avoid taking place traffic accident.

The utility model advantage is to implement convenient and simple, and is with low cost.

Description of drawings:

Fig. 1 is the utility model structural representation.

1 is the car light lampshade, and 2 is polarizer, and 3 is light source.

The specific embodiment:

Manufacture process of the present utility model is such: at first produce glass identical with former vehicle or lucite lampshade according to the lampshade structure of existing various vehicles with structure.With the high adhesive of transparencies such as canada balsam the polarizer film is bonded at then and makes on the good lampshade, but owing to be bonded at outside wearing and tearing easily, preferred version promptly is bonded in the lampshade.The direction of shaking thoroughly of polarizer film sees it should is that a left side is low right high from the lampshade inboard, promptly be the ground vertical direction to right avertence 45 degree angles.The polarising glass that driver or pedestrian wear also is with the high adhesive of transparencies such as canada balsam the polarizer film to be bonded on the common spectacles sheet to make, the direction of shaking thoroughly of its polarizer film sees it also is that a left side is low right high from the glasses inboard, promptly in vertical direction to right avertence 45 degree angles.The production principle of polarizer film is to stretch the heating of polyvinyl alcohol book film and along a fixed-direction, and the microscler molecule of polyvinyl alcohol is marshalling when stretching.Then the film immersion is contained in the water of iodine, iodine molecule is attached to forming a rule iodine chain on the polymerizable molecular of long-chain shape.It just looks like the same along guidewire movement that the free electron of iodine molecule moves along long-chain.The polarizer lampshade made from this film absorbs and is parallel to the polarised light of iodine chain vibration, and allows the polarised light perpendicular to the iodine chain vibration pass through.Polarizer film market is on sale.

Claims

1. polarized light lamp, it has light source, lampshade, it is characterized in that: polarizer is installed on the lampshade, polarizer is installed is made its direction of shaking thoroughly for from vertical ground direction direction 45 degree angles that tilt to the right or to the left.

2. polarized light lamp according to claim 1 is characterized in that: its polarizer can adopt the polarizer film to be attached to the lampshade inner surface.
