Abstract

The invention relates to a light-transmitting concrete-based LED active luminous traffic marking and a construction method thereof. The luminous traffic marking comprises a light-transmitting concrete layer and a light source layer arranged up and down, wherein the light-transmitting concrete layer comprises a concrete base and a light source layer. A number of light guide fibers embedded in the concrete matrix, the light source layer includes an integrated LED light source board and an encapsulation protective shell for encapsulating the integrated LED light source board, the encapsulation protective shell is an anchored hollow The protruding casing, the encapsulating protective shell is anchored and connected with the concrete base through the anchoring type hollow protrusion. Compared with the prior art, the invention enhances the visibility of road traffic markings, improves its digitization and intelligence level, and has broad application prospects.

Description

technical field [0001] The invention belongs to the field of road traffic, and relates to a light-transmitting concrete-based LED active luminescent traffic marking and a construction method thereof. Background technique [0002] Traffic markings play a very important role in maintaining the order of road use, improving the level of traffic safety, and improving the efficiency of vehicle traffic. Studies have shown that the effectiveness of traffic markings depends on their visibility. [0003] At present, the main way to enhance the visibility of road traffic markings is to increase their brightness. According to the lighting method, traffic markings can be divided into passive lighting type and active lighting type. Passive luminescent markings use the principle of retroreflection of light to achieve passive luminescence. This type of marking has been widely used, accounting for more than 99% of the total road markings. The visual recognition performance under environme...
