How Do Solar Powered LED Cats Eyes Work On The Road?


Solar Powered LED Cats Eyes, also be known as solar road stud or led cats eyes,is a kind of road studs, always setting along the road surface, cat eyes on road used to indicate the direction of the road at night or in rain and fog weather, led cats eyes composed of reverse reflection material, shell, solar panel, LED, control device, visual induction facility with active luminous and passive reflective performance, usually combination with marking when use them.

The solar powered cats eyes is composed by the solar panel, LEDs, accumulator and the shell.The working principle of solar powered LED cats eyes 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.

In the absence of street lights, solar powered LED cats eyes are a good solution, both safe and sustainable infrastructure, providing superior distance visibility ahead of the road layout. LED cats eyes start at the beginning of dusk. Once the sun exceeds 100 lux in the morning, the lightning goes out and the battery starts charging. Cat eyes on road maintain light output throughout the annual cycle and have been shown to increase the safety of night time. Even on cloudy or rainy days,the solar powered cats eyes will be effectively charged to 100% in about 3 hours.

LED cats eyes Embedded in the road surface, they are an electronic improvement on the traditional cat's eyes in that they may give drivers more than a thirty-second reaction window compared with about 3 seconds for conventional reflective devices. The intense brightness of the LEDs makes them easily visible at distances of about 900m under favourable conditions.
