Abstract
Description
Technical Field
[0001] The utility model relates to the field of traffic signs, and particularly to a traffic sign used in a backlight environment. Background Art
[0002] A traffic sign is a traffic facility with an indicative and warning function for displaying road traffic information. The sign is usually marked with words, graphics, etc. for displaying traffic regulations and road information. Generally, traffic signs are made of metal materials and installed on both sides of the road. There are also some traffic signs installed directly above the road through special brackets; in certain specific situations, especially when driving at high speed on a highway, when the driver, the road sign, and the sun are in the same direction or approximately in a straight line, the sun or the bright sky background will cause a "backlight" phenomenon when the driver observes the road sign, making it impossible for the driver to clearly see the road sign, thus affecting the prompting and warning functions of the road sign. At the same time, when the driver tries hard to see the road sign for a long time, it will affect the observation of other road conditions, posing a huge potential safety hazard during the driving process.
