## Abstract

The present disclosure relates to an LED active luminous traffic marking based on light-transmitting concrete and a construction method thereof. The luminous traffic marking includes a light-transmitting concrete layer and a light source layer that are arranged vertically, where the light-transmitting concrete layer includes a concrete base and a plurality of light-guide fibers embedded in the concrete base, the light source layer includes an integrated LED light source board and a packaging protective shell for packaging the integrated LED light source board, the packaging protective shell is a shell with anchoring hollow protrusions, and the packaging protective shell is anchored to the concrete base through the anchoring hollow protrusions. Compared with the prior art, the present disclosure improves the visibility, digitalization and intelligence level of road traffic markings, and has a broad application prospect.

## Claims

### Claim 1

A light emitting diode (LED) active luminous traffic marking based on light-transmitting concrete, comprising: a light-transmitting concrete layer and a light source layer that are arranged vertically, wherein
the light-transmitting concrete layer comprises a concrete base and a plurality of light-guide fibers embedded in the concrete base, wherein the light-guide fiber comprises an inward light-guide fiber and an outward light-guide fiber, wherein the outward light-guide fiber is an inclined outward light-guide fiber,
the light source layer comprises an integrated LED light source board and a packaging protective shell for packaging the integrated LED light source board, wherein the integrated LED light source board comprises a circuit board and a solar panel, LED lamp beads, a storage battery, and control devices that are integrated on the circuit board, and the position of the solar panel corresponds to positions of the inward light-guide fibers, and positions of the LED lamp beads correspond to positions of the outward light-guide fibers, and wherein the inward light-guide fibers guide external light to provide energy for the solar panel, and the outward light-guide fibers guide light generated by the LED lamp beads out of the LED active luminous traffic marking based on light transmitting concrete,
the packaging protective shell is a shell with anchoring hollow protrusions, and the packaging protective shell is anchored to the concrete base through the anchoring hollow protrusions, wherein a quantity of the anchoring hollow protrusions corresponds to a quantity of the light-guide fibers, and when the packaging protective shell is anchored to the concrete base, the light-guide fibers pass through hollow portions of the anchoring hollow protrusions,
wherein when the packaging protective shell packages the integrated LED light source board, LED lamp beads are inserted into hollow portions of the anchoring hollow protrusions.

### Claim 2 (depends on 1)

The LED active luminous traffic marking based on light-transmitting concrete according to claim 1, wherein raw materials of the concrete base comprise cement, aggregate, a superplasticizer, and water.

### Claim 3 (depends on 1)

The LED active luminous traffic marking based on light-transmitting concrete according to claim 1, wherein a joint between the light-guide fiber and the anchoring hollow protrusion is provided with a sealing waterproof layer.

### Claim 4 (depends on 1)

The LED active luminous traffic marking based on light-transmitting concrete according to claim 1, wherein the LED lamp beads are monochromatic lamp beads or RGB multi-color lamp beads.

### Claim 5 (depends on 1)

A construction method for the LED active luminous traffic marking based on light-transmitting concrete according to claim 1, comprising:
(1) making and commissioning the integrated LED light source board;
(2) packaging the integrated LED light source board in the packaging protective shell;
(3) inserting the light-guide fibers into the anchoring hollow protrusions, setting up a concrete pouring mold on the packaging protective shell, and fastening the light-guide fibers through a holed mold;
(4) pouring a cement concrete slurry into the concrete pouring mold, and after standard curing, demoulding, and continued standard curing, carrying out grinding and polishing to obtain the luminous traffic marking; and
(5) embedding the luminous traffic marking into a pavement structure, and ensuring that a surface of the luminous traffic marking is flush with a road surface.
