Solar road stud is a kind of spike, which is set along the road surface and used at night or in rain or fog to indicate the direction of the road. It is composed of reverse reflection material, shell, solar panel, LED and control device. It is a visual induction facility with active luminescence and passive reflection performance, which is usually used in combination with the marking line. The working principle of solar energy road stud, solar panels absorb sunlight during the day, the solar energy into electrical energy stored in the storage devices (batteries or capacitors), in the evening, the electricity automatically converted into light energy storage device (through the photoelectric switch control), through the LED light path outline, induce the driver line of sight.
This cast aluminum reflective solar road stud battery, life of more than 10 years, IP68, the solar panel area is larger, charging efficiency increased by 30%, more suitable to press in the road stone such as vehicle pressure does not fall.
