Ray self-adaptive signal light

Abstract

The invention discloses a ray self-adaptive signal light which comprises a signal light, a photosensitive head, a selector switch, a single chip microcomputer and a plurality of adjusting control units, wherein the photosensitive head and the selector switch are respectively connected with one end of the single chip microcomputer, the other end of the single chip microcomputer is respectively connected with the adjusting control units which are connected with the signal light. Rays are converted into voltage analog signals through the photosensitive head then to be transmitted to the single chip microcomputer, the voltage analog signals are converted into digital signals by the single chip microcomputer, and corresponding current is adjusted and controlled by each adjusting control unit in accordance with the digital signals. The signal light is used for controlling light in accordance with the gear of the selector switch and current strength. According to the ray self-adaptive signal light, different commands can be executed in accordance with the strength of an input light signal, so as to perform light control, all lighting and half lighting control and intelligent automatic control, the effect of energy saving is achieved, and the humanization design of traffic roads is realized.

Description

technical field [0001] The invention relates to a signal lamp in the field of electronic technology, in particular to a light adaptive signal lamp. Background technique [0002] Road traffic signal light is a traffic safety product, and it is an important tool to strengthen road traffic management, reduce traffic accidents, improve road use efficiency, and improve traffic conditions. Applicable to intersections such as crosses and T-shaped intersections, it is controlled by road traffic signal controllers to guide vehicles and pedestrians to pass safely and orderly. [0003] LED (Light Emitting Diode) is a new type of light source developed and produced in recent years. It has low power consumption (current is only 10-20mA), high brightness (light intensity can reach tens of thousands of mcd), and small size (the minimum diameter can reach 3mm). , light weight (a light-emitting diode weighs only a few tenths of a gram), long life (average life of 100,000 hours), etc. It ha...

Problems solved by technology

[0004] Existing signal lights work in a fixed current mode, the average power is high, and a lot of energy is wasted. Not only that, but also forms a strong contrast with the ambient light

When the ambient light is strong, the contrast signal light is dark, and when the sun is backlit during the day, the driver cannot see the signal light clearly; when the ambient light is weak, the contrast signal light is too strong, and when the signal light is too bright late at night, it will cause dazzling, causing discomfort to the driver's eyes
