In terms of road lighting,
cat eye road stud with LED lights are required to be used in new road lighting projects and energy-saving renovation projects.
The solar cat eye road studs with LED is a directional light source with low scattering rate and high luminous efficiency. The solar cat eye road studs 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 cat eye road studs 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.
