Method for enhancing capability of traffic lights to penetrate haze

Abstract

The invention discloses a method for enhancing the capability of traffic lights to penetrate haze. The method includes the following steps that: step 1, an LED lamp bead array is adopted, two chips are arranged inside each LED lamp bead, wherein one of the two chips is a green light chip, and the other chip is a red light chip; step 2, the green light and the red light chip of each LED in the step1 are connected with a driving circuit; step 3, the operating current of the red light chip and the green light chip is change by the driving circuit separately; step 4, the current ratio of the redlight chip and the green light chip is also changed accordingly according to the step 3; step 5, the magnitude of the current in the step 4 is used for controlling the luminous flux of a hybrid lightsource, and therefore, the light intensity of the light source can be controlled, and the current ratio is used for controlling the spectrum color of the hybrid light source; and step 6, on the basisof the step 4 and step 5, the traffic lights can have the spectrum color and light intensity which make the traffic lights better penetrate the haze and be recognized by eyes more easily under different smog environments.

Description

technical field [0001] The invention relates to the field of traffic control equipment, in particular to a method for enhancing the ability of traffic signal lights to penetrate fog and haze. Background technique [0002] In recent years, the smog weather in many cities in China has continued to increase, causing many problems for traffic management. In smoggy weather, especially in heavy smog environments, driving visibility is low, vision is unclear, and traffic safety facilities such as signal lights have poor identification effects, which is not conducive to the driver's correct observation and judgment of the front and road environment. Prone to rear-end collisions and collisions. [0003] The penetration performance of different light source wavelengths in the haze environment is different. Some studies have proved that in foggy weather, the fog penetration of wavelengths is: yellow light > red light > green light > blue light. In foggy days, yellow light o...
