The Working Principle of Solar Cats Eyes on Road

Solar cats eyes is a LED maintenance-free lighting equipment powered by solar cells, which is used for road construction to depict the edge and center line of the road. They are usually embedded in the road, solar cats eyes is an electronic improvement on the traditional cat eyes on road,they can provide drivers with more than 30 seconds of reaction time, compared with the traditional reflection device of about three seconds. The strong brightness of LED makes them easy to see at a distance of about 900 m under good conditions.

The average size of solar cats eyes is about 100 square mm or 100 mm in diameter, about 40 mm thick and is very strong enough to avoid damage to vehicles when passing through, usually made of engineering plastics and polycarbonate. The advantage of solar cat eyes on road is that they can reduces the dazzling and attendant dangers from headlights. In rainy and foggy days, and in the case of problems with old mirrors and road markings, their effects are also very obvious. Solar cells charge batteries or capacitors in the sun, during which time the photoelectric switch controls the LEDs.

The flashing model of solar cats eyes usually has tree types:flashing,constant and synchronous flash.

The working principle of solar cats eyes on road is that solar panels absorb sunlight during the day, cat eyes on road convert solar energy into electricity, and store it in energy storage devices (batteries or capacitors). At night, the electric energy in the energy storage device is automatically converted into light energy (controlled by photoelectric switches), and bright light which emitted by LED providing a view of the road layout ahead in the driver's natural line of vision.
