AI Technical Summary

Technical Problem

Existing in-ground luminous road studs suffer from insufficient compressive strength, short light range, complex installation, and a tendency to develop cavities, leading to easy equipment damage and high maintenance costs.

Method used

It adopts a metal outer shell, a light-transmitting inner shell, and a layered shell structure design. The LED beads are tilted and filled with light-transmitting colloid. Combined with solar power supply and communication module, it is installed by utilizing the leveling properties of the filler material with a density greater than that of the filler.

Benefits of technology

It improves the compressive and impact resistance of road spikes, ensures good light projection distance and visibility, simplifies the construction process, avoids equipment settlement and cavity problems, and reduces maintenance costs.

Abstract

The application provides a buried light-emitting pavement marker, a mounting method thereof and a smart pavement marker system, which comprise an outer shell, an inner shell, a light module, an energy module and a communication module fixed in the inner shell; the top of the outer shell and the inner shell is flush with the buried reference surface; the inner shell is a cap-shaped member with a transparent top; the material strength of the outer shell is higher than that of the inner shell; the light module comprises a circuit board and lamp beads arranged in an array, the lamp beads are at least two columns and are fixed on the upper surface of the circuit board in opposite inclinations; the center of the light-emitting surface of each column of lamp beads is arranged in an inclination relative to the bottom surface of the circuit board, so that the projection light emitted by the opposite column of lamp beads is in reverse cross irradiation; the top cover of the inner shell is filled with a first gel with light transmission between the solar panel and the lamp beads; the gap between the energy storage element, the circuit board and at least the inner shell towards the top cover is filled with a second gel, so that the energy storage element, the circuit board and part of the inner shell form an integrated sealed structure.
