Solar Road Stud
Dec 12, 2014

A solar road stud is a type of spike that is set along a road surface and is used at night or in rain and fog to indicate the direction of the road, and is made of a retroreflective material, a shell, a solar panel, LED, control device composition, with active lighting and passive reflective performance of the visual induction facilities, usually combined with the use of reticle.


High brightness

Reflective brightness of ordinary reflective spikes is only 300-400 MCDs, and the brightness of solar spikes can reach 2000 MCDs or more, which is 6-7 times that of the former. High-intensity light can break through rain and fog at night, safely and effectively. Guidance for the driver.

Active light, dynamic alert

Solar spikes flash at a certain frequency at night, and human vision is more sensitive to changes, so its dynamic warning is very strong. Active light emission can not only avoid the interference of rain and fog to the greatest extent, but also can depart from the dependence on automotive lighting, and it can have a farther visual distance and better effect.

Solar spikes play an important role in rain and fog weather, as well as in contouring road contours, inducing the driver's vision and eliminating potential safety hazards.

Working principle

During the day, solar panels absorb sunlight and convert solar energy into electricity.

Stored in the energy storage device (battery or capacitor), at night, the energy in the energy storage device is automatically converted into light energy (controlled by a photoelectric switch), and the outline of the road is outlined by the light emitted by the LED to induce the driver's line of sight.

Solar studs can be divided into buried and protruding type according to different installation positions.

The former is generally used in the midline, the latter is generally used for the edge line. This is because the solar-powered spikes installed in the center line require particularly high pressure resistance. In order to solve this problem, they had to bury the solar-powered spikes on the ground, leaving only about 5 mm of ground exposed. The requirements of the solar studs used on the edge line to resist pressure performance are not particularly high, and the protruding ground can still work effectively.

Solar energy spikes can be divided into capacitive and battery type according to the different energy storage components. The former can have a service life of five to seven years, and the latter can generally have a service life of one to three years.

Because buried solar studs are very damaging to the road surface, and the cost of capacitive solar studs is too high, the most widely used solar battery spikes are currently raised.
