Principle of Tripod Warning Sign

The reflective part in the warning sign is made by using the retro-reflective principle of high-refractive-index glass beads and the micro-diamond-shaped reflective principle of the reflective crystal lattice, and is made by advanced processing after focusing. It can reflect the distant direct light back to the light-emitting place, and has good retroreflective optical performance no matter in day or night. Especially at night, it can display the same high visibility as during the day. Warning signs made of this high-visibility reflective material can be easily spotted by night drivers no matter if the user is in a remote place or under the interference of light or scattered light. The emergence of reflective materials successfully solved the night driving problem of "seeing" and "being seen".
