Embodiment Construction

[0023] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0024] A kind of traffic signal light suitable for normal and color-blind people of the present invention adopts the following technical scheme:

[0025] refer to figure 1 , figure 2 As shown, a layer of Newton ring film is installed outside the red signal light, that is, a plano-convex lens with a large radius of curvature. When the red signal light is on, circles of light and dark stripes of equal thickness will be produced on the outside of the film. The convex side of the plano-convex lens is tightly installed with a red signal light. When the red light is on, a series of concentric rings with alternate light and dark will be formed on the film with the contact point as the center; the...

Abstract

The invention discloses a traffic signal lamp suitable for being used by normal and colorblind people. The traffic signal lamp is formed by a traffic signal lamp body. A layer of interference film is installed outside the traffic signal lamp body. A layer of Newton ring film is installed outside a red signal lamp. A layer of wedge interference film is installed outside a green signal lamp. Through adding one layer of the interference film outside traffic lights, colorblind or color-weakness people can distinguish traffic signals through different shapes of stripes displayed on the film.

Description

technical field [0001] The invention belongs to the technical field of traffic signal lamps, in particular to a traffic signal lamp equipped with an interference film on the outside and suitable for sharing by normal and color-blind people. Background technique [0002] At present, more than 60 million people in my country are color-blind patients, and the frequency of color-blindness gene carriers in China is 8.98%. my country's traffic law stipulates that color blindness and color weakness cannot obtain a driver's license, because even if arrow signal lights are used at some intersections, they still cannot distinguish the color of the arrow. If there is a kind of signal light that can make color-blind and color-blind patients see clearly, it can solve many problems of color-blindness and color-blindness crossing the street. It can also realize their driving dreams, provide them with a safe driving environment, and provide more reliable traffic safety for the country guar...
