The faster the urban modernization develops, the more the road and urban public lighting needs will expand, and the demand for public lighting energy will increase. According to the requirements of the "City Road Lighting Design Standard CJJ45-2006" document, urban road lighting must use high-pressure sodium lamps, metal halide lamps, compact or thin-tube fluorescent lamps for road lighting. Through long-term cooperation with Japanese light source research experts, we have boldly tried to research and develop ceramic xenon bulb electric light source products and matching micro-computer controllable ballasts.
The ceramic xenon lamp derived from high-pressure gas discharge lamps such as high-pressure sodium lamps and metal halide lamps has changed the weakness of the past products and developed into high-quality electric light source products with high luminous efficiency, high color rendering, high brightness and low power consumption. Its use effectively saves electricity consumption, reduces lighting electricity bills, and increases urban glory. Let urban roads and public lighting achieve practical energy-saving effects.
First, the purpose of urban road lighting
The purpose of urban road lighting is to brighten urban roads, illuminate the road for vehicle drivers and pedestrians, create a good visual environment, ensure traffic safety and improve transportation efficiency; municipal lighting is convenient for people's lives and reduces crime rate. At the same time, it also achieves the purpose of beautifying the urban environment.
Second, the comparison of urban road lighting using electric light source products
At present, the electric light source products selected for urban road lighting mainly include high-pressure sodium lamps, metal halide lamps, and fluorescent lamps. Among them, high pressure sodium lamps are the most widely selected products. Below, we compare the two electric light sources, let you visually see who is better, which is more suitable for the current modern urban development needs.
