Night road surface light-emitting diode (LED) lamplight guiding system

Abstract

The invention provides a night road surface light-emitting diode (LED) lamplight guiding system. The night road surface LED lamplight guiding system aims at a situation that signs and marked lines in an existing traffic system are prone to being misjudged or ignored by passengers and drivers when night illumination is in a bad condition, and traffic accidents are caused. The night road surface LED lamplight guiding system combines an effective energy-saving LED illumination technology, a solar photovoltaic illumination technology, inlaid application technologies of micro-controllers such as a microprogrammed control unit (MCU) and a field programmable gate array (FPGA), and the signs and the marked lines of road traffic guiding so as to achieve a working mode by using an intelligent traffic system which adopts signs and marked lines guided by LED lamplight, and reasonably arranged subsystems such as night LED guiding arrows, solar LED underground lamps, sidewalks (zebra crossings) road surface LED lamplight guiding and stop mark laser curtain walls. The night road surface LED lamplight guiding system can build a safe traffic environment for the passengers and traffic vehicles, and meanwhile can serve as an important constituent part of night landscape lighting of cities so as to enable a traffic guiding system to be artistic and humanized, and guide the passengers and the drivers to consciously obey the traffic rules, travel safely and return homes safely.

Description

[0001] Technical fields: LED light guidance (vehicle) indication system for pavement at night, LED pedestrian guidance system for zebra crossings, LED lighting system application, laser curtain wall technology, solar LED buried lights, road LED light guide arrows, LED indicating lane dividing lines Background technique: [0002] At present, road lighting at night in China and even the world is dominated by street lamps. In most cases, street lamps can provide sufficient lighting so that drivers and pedestrians can clearly understand the road conditions and the conditions of vehicles and pedestrians in front and behind. The sidewalk on the road (hereinafter referred to as zebra crossing) belongs to the traditional way, and alternate white zebra crossings are painted on the section of pedestrian traffic, which generally cooperates with traffic lights to restrict pedestrians and passing vehicles. However, there are many problems in this traditional lighting and guidance method. Th...

AI Technical Summary

Problems solved by technology

However, there are many problems in this traditional lighting and guidance method. The street lights are scattered and the height of the lights is very high. Many road sections are poorly illuminated at night, especially at intersections where vehicles and pedestrians pass at the same time, which are prone to the following major safety hazards. :

[0003] First, at night, the width of the road is large, the lighting of the street lights is poor, and the traffic directional arrows near the road intersection are easily ignored by passing vehicles, and the vehicles are easy to go in the wrong lane, and they cannot change lanes at the intersection;

[0004] Second, the lane dividing line on the road at night is not obvious, and it is easy to be ignored. Vehicles crossing the guide lane line on the same side will cause the rear vehicles to be unable to move forward. Roads with heavy traffic volume are easy to block traffic, especially when vehicles change lanes at night. , cross the double yellow line in the middle of the road, and collide with the opposite vehicle, which is likely to cause a major traffic accident;

[0005] Third, there are often zebra crossings without traffic lights on the road. When the lighting is poor, vehicles driving on the road at night cannot find the zebra crossing ahead in time, cannot see the pedestrians on the zebra crossing clearly, and cannot slow down in time in advance, which is likely to cause traffic accidents. It is a great safety hazard for pedestrians on the zebra crossing;

[0006] Fourth, at night, at the zebra crossing indicated by traffic lights, the driver finds the zebra crossing, but cannot accurately and quickly judge the position of the stop line and the edge of the zebra crossing. impose penalties for violations;

[0007] Fifth, it is not easy for pedestrians to find zebra crossings on the side of the road at night. They do not know the location of zebra crossings, so they have to cross the road, which is likely to cause traffic safety accidents;

[0008] Sixth, pedestrians can easily walk outside the edge of the zebra crossing at night, and easily have traffic accidents with vehicles slowing down in front of the zebra crossing;
