The lighting bridge guardrail is a steel pipe with LED lamps inside the guardrail on both sides of the bridge. On the one hand, it solves the needs of bridge protection and lighting, and also replaces high pole street lamps for bridge deck lighting, which can solve the lighting of bends while maintaining the simplicity of the bridge deck.

The lighting function of the bridge guardrail is suitable for various road sections with guardrail facilities on both sides of the road. Using the steel pipe components used in the guardrail facilities as the installation carrier for the lamps, standard square holes and fixing screw holes are machined on the inside of the steel pipe, and the lamps are installed on it at a height of 1-1.5 meters. The illumination angle of the light spot of the lamp is inclined downwards, so that the light is concentrated on the road surface, presenting abundant illumination on the road surface, while the part above the height of the lamp has no illumination, which also avoids light pollution. Simultaneously utilizing optical principles to constrain the illumination angle of the lamp beam, solving the problem of glare in the direction of incoming vehicles.
