Solar Road Studs (Solar Stud or Solar Road Marker), is a kind of
road stud, set along the road surface, used at night or in rainy and foggy weather to indicate the direction of the road,
Solar Road Studs are made of retroreflective materials, shells, solar energy It is composed of board, LED and control device. It is a visual induction facility with active luminescence and passive reflection performance, which is usually used in combination with marking lines.
During the day,
Solar Road Studs absorb sunlight, convert the solar energy into electrical energy, and store it in the energy storage device (battery or capacitor). Bright light to outline the road and induce the driver's sight.
Solar Road Studs can be divided into embedded type and protruding type according to the different installation positions.
The former is generally used in the midline, and the latter is generally used in the edge line. This is because the
Solar Road Studs installed in the center line have particularly high requirements for compressive performance. In order to solve this problem, the
Solar Road Studs had to be buried in the ground, with only about 5 mm exposed. The
Solar Road Studs used on the edge line are not particularly demanding in terms of compressive performance, and they can still work effectively on the protruding ground.
Solar Road Studs can be divided into capacitive type and battery type according to the different energy storage elements. The service life of the former can reach five to seven years, and the service life of the latter generally ranges from one to three years.
