Problems solved by technology

However, anti-glare in this way may be over-anti-glare, making the background of the field of view too dark, and even blocking signals that should not be blocked, hindering the visibility of the pulse lighting anti-glare system

Embodiment Construction

[0007] The light baffle is an electronically controlled optical switch device, which is made into a plate shape or a glass shape. In order to adjust the light transmittance of the light baffle, it can work in the switch mode by changing the time ratio of opening and closing, or it can work in the In the analog mode, different light transmittances can be obtained by changing the applied voltage. In this method, the two methods are equivalent. An embodiment is given below according to the switching operation mode, and the method is more specifically described through the description of the implementing device in combination with the concept of duty cycle in the background technology.

[0008] To give a simple example, in the sun, a lighting lamp of several thousand watts is not enough to dazzle; but at night, a flashlight of less than one watt is enough to blind people's eyes. This shows that whether the incident light at a certain place in the field of view can cause glare to t...

Abstract

A method and equipment for increasing the visual performance of the antidazzle system of pulse lighting features that on the basis of the variation in the ratio of dazzle light to background light in visual field and the parameters set up by user, the light transmission rate of pulse switch in the flash gap of pulse headlight is regulated to ensure that the background light is transmitted as more as possible in the antidazzle prerequisite, so providing an optimal antidazzle and observing effect.

Description

technical field [0001] The invention relates to vehicle lamp lighting technology. Especially the anti-glare lighting technology of pulse lights Background technique [0002] In Chinese patent application 93114064.1, it is proposed to use a pulse lamp with a small duty cycle and a high-speed strobe as a car lighting lamp, and the driver observes through a light barrier that is opened and closed synchronously with the pulse lamp, so as not to affect the lighting observation effect. Under the premise, most of the glare is blocked, and the purpose of anti-glare is achieved. However, anti-glare in this way may be excessively anti-glare, so that the background of the field of view is too dark, and even blocks signals that should not be blocked, hindering the visibility of the pulse lighting anti-glare system. Contents of the invention [0003] In order to solve the above-mentioned defects in the background technology, the present invention proposes a method, that is, when the ...
