Multifunctional traffic signal light and control circuit and light box

Abstract

The invention discloses a multifunctional traffic signal lamp, a control circuit and a lamp box. The signal lamp comprises a green lamp signal display unit composed of green light-emitting diodes, a red lamp signal display unit composed of red light-emitting diodes and a yellow lamp signal display unit composed of yellow light-emitting diodes, wherein the green lamp signal display unit, the red lamp signal display unit and the yellow lamp signal display unit are respectively provided with a prompt area for prompting in different time in a time period displayed by the corresponding display unit, and the three display units are arranged on the same LED lamp board in an overlapping mode. The control circuit is provided with a green lamp signal drive unit, a green lamp signal display and control unit, a yellow lamp signal drive unit, a yellow lamp signal display and control unit, a red lamp signal drive unit and a red lamp signal display and control unit. The lamp box is a lamp box body integrally formed by a top panel, a rear panel, a left panel and a right panel, and a bottom end cover is arranged on the bottom side of the lamp box body. The multifunctional traffic signal lamp, the control circuit and the lamp box are simple in structure and suitable for various people.

Description

technical field [0001] The invention relates to a traffic signal lamp. In particular, it relates to a multifunctional traffic signal lamp capable of reflecting a sense of time, a control circuit and a light box. Background technique [0002] The devices used to guide pedestrians and vehicles to pass at traffic intersections. At present, what we have seen is basically three different colors of red, green and yellow erected at the intersection to guide pedestrians and vehicles to stop, pass, and green. Traffic lights for states such as red transition, left turn, and right turn. [0003] But, existing this traffic signal lamp, signal display is relatively single, and the display of red, green and yellow three kinds of lamps all is the same shape, does not have any difference except color. This is no problem for normal people, but for people with eye problems, such as color-blind people, they may not be able to tell which is red, which is green, and which is yellow, so traffic...

Problems solved by technology

[0003] However, the existing traffic signal lights have a relatively single signal display, and the displays of the red, green and yellow lights all have the same shape, and there is no difference except the color.

This is no problem for normal people, but for people with eye problems, such as color-blind people, they may not be able to tell which is red, which is green, and which is yellow, so traffic accidents are prone to occur
