Problems solved by technology

[0002] At present, the signal devices at urban road intersections use circular signal lights to alternately display red and yellow colors for command, but color blind and color weak people cannot distinguish between red lights and green lights, which brings inconvenience to them when crossing the road
Some cities adopt a new type of cylindrical upright traffic light, which is very beautiful in appearance, but either all red lights, all yellow lights, or all green lights are displayed, which is not conducive to the traffic safety of colorblind and color weak people.

Embodiment Construction

[0012] Referring to the accompanying drawings, a traffic signal device includes a lamp holder, a lampshade and a signal lamp, and is characterized in that the lamp holder is provided with three signal lamps of different shapes, namely, a round red lamp, a flat square yellow lamp and a vertical rectangular green lamp. . In this embodiment, the uppermost part is a circular red light, the middle part is a "one" shaped yellow light, and the lower part is a "1" shaped green light. The inner side of the signal lamp is provided with a concave-convex mirror that gathers light and increases the brightness of the signal, and inside the concave-convex mirror is a multi-angle reflective polygon that increases the reflected light.

[0013] The three signal lamps of different shapes are provided with matching black lampshades A respectively.

Abstract

The invention relates to a traffic signal device of city crossroads. It is to set up ' one round two rectangle ' signal lamps on the lamp bracket, they are circular red light, flat square yellow light and erects rectangle green light, setting up matching lamp shade A on each signal lamp. It is against the color defect of the appointed crowd as color blind and tritanope, therefore using innovation design on the signal lamp form, distinguishing the red, yellow and green lamp by the difference form, the appointed crowd as color blind and tritanope receive the correct traffic signal by the bright or black of the lamb in different form. It can be ensured the traffic demands of both everyman and the peculiar crowd; this is personalization traffic red yellow green light.

Description

technical field [0001] The invention relates to a traffic signal device at a road crossing. Background technique [0002] At present, the signal devices at urban highway intersections use circular signal lights to alternately display three colors of red and yellow for command, but color blind and color weak people cannot distinguish between red lights and green lights, which brings inconvenience to them when crossing the road. Some cities adopt a new type of cylindrical upright traffic light, which is very beautiful in appearance, but either all show red lights, or all show yellow lights, or all show green lights, which is not conducive to the traffic safety of color blind and color weak people. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned defect, provide two kinds of traffic signal devices that can make color-blind and color-weak people understand at a glance. [0004] The technical solution of the present inventi...
