1) Solar Road Studs is limited by the clearance of the tunnel, so the layout is mainly graphic.
2) The brightness of the electro-optic sign is greater than 15-300cd/m2.
3) The box body is made of corrosion-resistant materials, such as galvanized steel and aluminum alloy materials, and the protection level is not less than IP65. Tubes, made in the form of light boxes, are the earliest electro-optical signs.

The intensity and viewing angle performance of Road Studs red light are the standards strictly controlled by the state in the application process of signal lights. In particular, there are clear regulations on the light intensity of Road Studs red signal, but there are no specific regulations on the light intensity of yellow and green signals. According to GB14887-2003, the national road traffic signal light standard of the People's Republic of China, if the red signal can meet the specified light intensity requirements, then the yellow Road Studs light and the green signal light can meet the requirements.

The most commonly used light sources in traditional light source Solar Road Studs lamps are incandescent lamps and halogen lamps. For example, the technical indicators in my country's signal lamp standard GB14887-94 and Australian standard AS2144 are mainly for incandescent light sources. The BS505 standard used was developed for halogen lamps.

The safety Solar Studs light is a kind of safety warning light, which is mainly installed on both sides of the highway in rainy and foggy conditions. It has synchronous flashing and anti-rear collision warning functions. It can automatically switch working modes with weather monitoring instruments.

The light source adopts four element ultra high brightness light emitting diode (LED), which has the characteristics of strong brightness, long life, good energy-saving effect and easy

Solar road studs are safety devices installed on the road and are subjected to the crushing and impact of vehicles many times a day.
