Traffic signal lamp structure for avoiding false display

Abstract

The invention discloses a traffic signal lamp structure for avoiding false display. The traffic signal lamp structure comprises a supporting rod and a bulb, a parabolic reflector is arrange don the supporting rod and vertically connected with the supporting rod, a rectangular base is arranged at one end of the parabolic reflector, an opening is formed in the other end of the parabolic reflector, the parabolic reflector is recessed inwards from the opening to form a paraboloid, a colorless lens is arranged at the opening of the parabolic reflector, the bulb is arranged on the base of the parabolic reflector, one surface of the colorless lens is connected with the parabolic reflector, the other surface of the colorless lens is connected with a light shield, a square is arranged on the upper portion of the light shield, quarter circles are connected with two sides of the light shield, and the radius of each quarter circle is equal to the edge length of the square. By the aid of the colorless lens, when an incandescent light bulb is replaced into an LED (light-emitting diode) bulb and the included angle between the sun and the ground is excessively small, the LED bulb penetrates the colorless lens through the parabolic reflector and is seen by a driver, and the illusion of false display for the driver is avoided.

Description

technical field [0001] The invention relates to a traffic signal lamp, in particular to a traffic signal lamp structure for avoiding false display. Background technique [0002] Traffic lights are a traffic safety management facility. Traditional traffic lights are mainly composed of power supply, light bulb, lamp housing, parabolic reflector and colored lens. The light source is an incandescent lamp or a halogen tungsten lamp. The mains can directly supply power to the incandescent lamp. For the halogen tungsten lamp, the mains needs to be converted by a transformer before it can be powered; the function of the parabolic reflector is to collect the light emitted in all directions and move forward. Exit; The function of the colored lens is to reasonably distribute the white light emitted forward to produce red, yellow and green three-color light. At present, signal lights are widely used, and due to the existence of parabolic reflectors, false display effects are caused. ...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the problem in the prior art that it is easy to see the false display of the traffic signal light in the driver's perspective due to light problems at dusk and early morning, which causes the driver to judge the wrong display of the signal light, and provides a traffic signal light structure for avoiding false display. When it is applied, it can effectively solve the problem of false display of traffic lights and prevent drivers from making mistakes in judging traffic lights
