Adaptive traffic lights in haze environment

Abstract

The invention discloses a traffic signal lamp adapting itself to a haze environment. The traffic signal lamp comprises a visibility test module, a power supply module, a light adjusting module, a controller module and a traffic signal lamp module. According to the invention, by improving a current traffic signal lamp, the visibility test module and the light adjusting module are added; in order to ensure light intensity of the traffic lamp, ultra-high brightness diodes are used as light emitting diodes which are distributed on a lamp disc in high density, and different numbers of light emitting diodes in different positions are lightened in different conditions; and after the visibility of surround air is sensed, light emitting intensity of the signal lamp is automatically adjusted, so passengers and vehicle drivers can clearly obtain precise traffic signals and go out safely even in a haze.

Description

technical field [0001] The invention relates to the field of traffic control equipment, in particular to a traffic signal light that is adaptive to a haze environment. Background technique [0002] In recent years, the smog weather in many cities in China has continued to increase, causing many problems to traffic management. In haze weather, especially in heavy haze environment, the driving visibility is low, the field of vision is unclear, and the identification effect of traffic safety facilities such as signs, markings, and signal lights is poor, which is not conducive to the driver's correct observation and judgment of the front and road environment. Rear-end collisions and collisions are very likely to occur during driving. SUMMARY OF THE INVENTION [0003] Aiming at the shortcomings of the above-mentioned existing traffic signal lights that cannot be adapted to the haze environment, the applicant provides a traffic signal light that can adapt to the haze environmen...

Problems solved by technology

[0003] In view of the shortcomings of the above-mentioned existing traffic lights that cannot be adapted to the haze environment, the applicant provides a traffic signal light that can adapt to the haze environment, by using the air visibility detection module to sense the visibility of the surrounding environment, and then automatically adjust according to the visibility situation. The brightness of the traffic lights ensures that the traffic lights can issue clear traffic signals in foggy weather
