Safety PC Solar Road Stud Supplier In Korea
Solar road stud light-emitting devices should use LEDs, and the luminous intensity of a single LED at rated current, regardless of white, yellow, and red, should not be less than 2000 mcd, and the half-intensity angle should not be less than 15°. The number of LEDs is not less than 2 for each light-emitting surface. The service life of LED road stud lights is very long, generally speaking, the service life is about 3-5 years, and there is basically no need for manual maintenance during use.
Solar energy is a renewable source of energy that comes from the light and heat radiating from the earth and is harnessed by a range of evolving technologies. Solar cells can be used to convert heat energy into electricity through photothermal conversion. Solar technology is widely characterized as a passive or active way of capturing, converting, and distributing sunlight. Active solar technologies use solar photovoltaic panels, pumps, and fans to convert sunlight into a useful output. Passive solar technology involves selecting materials with good thermal properties, designing spaces for natural air circulation, and arranging the location of buildings in accordance with the sun. Active solar technologies, which increase the supply of energy, are considered to be on the supply side, while passive solar technologies, which reduce the need for alternative sources, are often considered to be on the demand side. Our solar road studs, however, use mainly photothermal conversion, which greatly reduces the consumption of electricity in cities, has a long life and requires no manual maintenance!
