The daytime solar panels absorb sunlight, converts solar energy into electric energy, stored in the energy storage device (a battery or capacitor), in the evening, energy storage solar warning light devices in the electric energy into light (automatic control through photoelectric switch), to draw the outline of road profile by LED light led barricade lights, induced by the sight of the driver.
Road safety studs according to the installation position can be divided into different embedding and projection type.
The former is generally used in the midline, which are generally used for edge line. This is because the installation in the midline of the solar energy spike on compressive performance requirements are particularly high, in order to solve this problem, but the solar energy spike embedded into the ground, only 5 mm above the ground. In the edge lines of solar energy spike for very high compression performance requirements is not above ground, still can effectively work.
Road safety studs according to the different storage devices can be divided into capacitance and cell type, the service life of up to five to seven years, the service life is generally one to three years.
Because the embedded type solar energy spike great solar powered warning light damage on the pavement, and capacitance type solar energy spike cost is too high, so most of the current application or convex type battery solar spike.
