Description

Technical Field

[0001] This utility model relates to the field of tunnel sign technology, and in particular to a vacuum-formed tunnel photoelectric sign. Background Technology

[0002] Tunnel photoelectric signs are safety facilities used for traffic flow guidance within tunnels. They emit bright light in dimly lit environments and feature standard traffic graphics and numbers, such as evacuation signs, telephone signs, fire signs, pedestrian crossing signs, vehicle crossing signs, and emergency stopping lane signs. Tunnel photoelectric signs generally use LED lights as the light source, and are characterized by their thinness, light weight, high brightness, long lifespan, and low energy consumption. They can also be combined with reflective film to ensure they still provide a reflective warning function in the event of a circuit failure.

[0003] In summary, the currently used tunnel optoelectronic signs consist of an aluminum profile frame, plastic corner pieces, acrylic or PC panels, LED beads and power supply, and mounting brackets. Due to the large number of disassembled parts, the complex assembly and disassembly, uneven light transmission of the panel, and weak structural strength, they are not conducive to installation and disassembly within tunnels. Therefore, we propose a vacuum-formed tunnel optoelectronic sign. Hence, a vacuum-formed tunnel optoelectronic sign is particularly needed. Utility Model Content
