Abstract

It relates to a tunnel LED light guide system for traffic warning. The LED is the light source and it is connected to the constant current drive circuit, the active road mark controller made of switch power, stabilizer filter circuit, oscillating circuit and amplified drive circuit, with the oscillating frequency of the oscillating circuit changed through resistance value of three relay control oscillating resistance, with optional manual or automatic control relay appliance.It has pre alarm signal, good guide action, low energy consumption, and three luminous frequency changeable virtue.

Description

technical field [0001] The invention relates to a traffic safety warning device, in particular to a tunnel LED lighting guidance system. Background technique [0002] As we all know, highway traffic safety is greatly affected by severe weather such as heavy fog, rain and snow, and sandstorms. Especially on highways, warning devices such as road studs and guardrail reflective nails with ordinary reflective displays often fail to function in bad weather with poor visibility, and traffic safety accidents such as vehicles running at high speed rushing out of the road and hitting the isolation guardrail occur from time to time . And at the entrance of the highway tunnel, the early warning signal of the reflective warning device is very weak under the weather with bad visibility, and the safety guidance effect is relatively poor, and the safety accidents that the vehicle hits the anti-collision bucket at the tunnel entrance often occur. Therefore, the existing reflective warning...
