Method for reducing glare of light supplement lamp of road traffic system

Abstract

The invention belongs to the technical field of road traffic lighting, and relates to a method for reducing glare of a light supplement lamp of a road traffic system. The method comprises the following steps of: acquiring a structural characteristic parameter value of the road traffic monitoring light supplement lamp and a set shooting distance; substituting obtained known parameters into a constructed anti-dazzle formula of the light supplement lamp, calculating the solutions of unknown parameters, and selecting the ranges of the suitable solutions; according to the selected results including a horizontal forward moving distance Lx, a vertical heightening distance Ly and a light blocking angle theta of the light supplement lamp, adjusting the glare of the light supplement lamp of the road traffic system or adjusting the installation structure of the light supplement lamp. Therefore, the glare of the light supplement lamp can be avoided and reduced, an effective illumination distance can be guaranteed, meanwhile, the glare problem of the light supplement lamp is solved, traffic safety is guaranteed. The method has an important practical value.

Description

technical field [0001] The invention belongs to the technical field of road traffic lighting, and in particular relates to a method for reducing the glare of a supplementary light in a road traffic system. Background technique [0002] With the development of intelligent transportation systems, higher requirements have been put forward for the quality of road traffic supplementary lighting systems. Road surveillance cameras must clearly and truly capture license plate numbers and road conditions in low-light or night-time environments, providing services for traffic law enforcement, Surveillance provides sufficient evidence. In order to shoot the target more clearly, the fill light is widely used in the road traffic system. [0003] The supplementary light satisfies the light requirements of the camera by increasing the brightness of the object. Usually, white LED is used. The LED has the characteristics of high brightness, strong directionality and good color rendering. It...

Problems solved by technology

[0004] In order to avoid the glare problem of the fill light, images can be taken under low-light conditions, but it will cause a series of problems such as a decrease in image quality, and it is difficult to guarantee the authenticity and reliability of the image

Therefore, there is currently no reasonable method of supplementary light for traffic roads that can not only ensure the clarity of imaging, but also effectively avoid glare.
