Traffic highway section vehicle identification LED infrared light supplementing device

Abstract

The invention relates to a traffic highway section vehicle identification LED infrared light supplementing device which is installed on an installation platform in the middle of a two-way lane and used for conducting infrared light supplementing on license plates of vehicles on a shooting road section of the two-way lane. The installation height of the light emitting part on the machine body is adjusted according to the height difference between the installation platform and the horizontal road section of the two-way lane, the distance between the light condensing part and the third reflector is adjusted according to the width of the shooting road section, and the rotation angle of the third reflector is adjusted according to the gradient of the two-way lane. And enabling the infrared light to just irradiate a license plate of a vehicle on the shot road section along a direction parallel to the shot road section. And energy waste and light pollution to passers-by caused by out-of-range light supplement are avoided while a good light supplement effect is obtained. Meanwhile, existing white light supplement is replaced by infrared light supplement, so that human eyes are prevented from being interfered.

Description

technical field [0001] The invention relates to the technical field of LED infrared lamps, in particular to an LED infrared supplementary light device for vehicle identification in a traffic high-speed road section. Background technique [0002] Cameras on traffic roads usually work around the clock. Among them, infrared cameras are mainly used for night shooting. The infrared cameras are usually integrated with LED infrared supplementary light devices. However, LED infrared lights have the problems of short night vision distance and short life. Nowadays, there are also solutions to install infrared fill lights or infrared cameras on the ground. However, the ground on both sides of the traffic road is dusty, and the small stones that are knocked off when vehicles pass at high speed will directly destroy the infrared fill lights, resulting in maintenance. higher cost.

Problems solved by technology

[0002] Traffic cameras usually work around the clock. Infrared cameras are mainly used for night shooting. Infrared cameras are usually integrated with LED infrared supplementary light devices. However, LED infrared lights have the problems of short night vision distance and short lifespan.

Today, there are also plans to install infrared fill lights or infrared cameras on the ground. However, the ground on both sides of the traffic road is dusty, and small stones that are knocked off when vehicles pass by at high speed will directly destroy the infrared fill lights, resulting in maintenance. higher cost

Simultaneously, the existing infrared supplementary lights are all fixedly installed on the frame. However, the shooting conditions of different road sections are different. For road sections with more large trucks, the installation height of the license plate is higher. In road sections, the installation height of the license plate is low, and the fixed installation of infrared supplementary lights cannot meet the needs of different road sections, while the movable installation of infrared supplementary lights will make the electrical configuration too complicated, thereby increasing the maintenance and installation costs

At the same time, the slopes of the shooting sections of different road sections are different, and the infrared light cannot travel parallel to the shooting section, resulting in poor lighting effects

At the same time, the lane widths of different road sections are also different. Over-the-range supplementary light will not only waste energy, but also cause light pollution to pedestrians on the roadside.
