Recently, in a circular document, the Guangzhou Municipal Bureau of ecological environment said in response to the proposal of the Municipal of the People's Congress that at present, Guangzhou's outdoor light pollution is mainly concentrated in urban nightscape lighting, commercial activities and outdoor advertising, signboard light pollution, etc. In term of road lighting, solar road stud markers with LED lamps are required to be used in new road lighting projects and energy-saving renovation projects.
The solar road stud marker with LED street lamp is a directional light source with low scattering rate and high luminous efficiency. The solar road stud marker with LED lamp efficiency can reach more than 95%. The luminous spectrum of it is concentrated in the visible part. With the promotion and use of solar road stud markers with LED lamps in the city, road lighting can effectively reduce light pollution while meeting the requirements of lighting and energy conservation and environmental protection.
The solar road stud marker is an eco-friendly rechargeable light-emitting device. This traffic safety facility for securing safe road environment at night or in bad weather condition with high luminance LED lights ON by solar energy without electricity. During the day time, the solar panel absorbs sunlight and converts the solar energy into electrical energy. At night, the electric energy in the super capacitor is automatically converted into light energy through booster circuit. This project of installing solar road stud markers provide a significant increase in the energy save and environment protect. The excellent control of light intensity of solar road stud markers with LED lamp also contribute to solve the light pollution.
