At present, most of the light sources of global road lighting systems are high pressure sodium lamps. High-pressure sodium lamp is a kind of gas discharge lamp with high intensity and high luminous efficiency (light efficiency up to 120lm/w). It has been widely used in large-area lighting places such as squares, roads, stations and docks.
In China, with the rapid development of the economy, the urban lighting process has accelerated, the urban service system has been continuously improved, and a large number of lighting and lighting facilities have been put into use, which has caused power shortages and high energy consumption, and the demand for electricity in the future will continue. This will create a huge contradiction with existing national policies such as energy conservation and environmental protection.
Under the premise of ensuring the rapid growth of total electricity consumption in the development of economy, life and safety, effective energy conservation, improvement of lighting quality and environmental protection are important issues and responsibilities of all lighting R&D, production and engineering units.
Shenzhen Platinum Optoelectronics Co., Ltd., as the key product of domestic high-pressure gas discharge lamp (HID), energy-saving and intelligent technology replacement, high-pressure gas discharge lamp (HID) electronic ballast research and development, production and practice, Leading enterprises with outstanding achievements and rich practical experience, developed electronic ballasts for AC and DC high-pressure sodium lamps, electronic ballasts for metal halide lamps, and electronic ballasts for low-pressure sodium lamps have been widely used in many projects at home and abroad. Applications have high impact and visibility in areas such as energy-efficient lighting, solar energy, and wind energy lighting.
In the long-term practice, Platinum Optoelectronics has continuously developed and developed the independent intellectual property rights (multiple national patents) low-pressure sodium lamp + metal halide lamp mixed-light energy-saving street lamps with the following characteristics:
1. Unique light distribution and exterior design effectively overcomes the glare problem in road lighting, improves the brightness of the road surface, and effectively reduces glare;
2. The reflector adopts vacuum coating technology to effectively improve the light reflection efficiency of the lamp by more than 20%, which greatly improves the system efficiency;
3, the use of metal halide lamp high luminous efficiency (80-100lm / w), high color temperature (5600K), high color rendering (95Ra) features effectively overcome the low temperature of low pressure sodium lamp (only 1800k) and poor color rendering ;
4, the use of low-pressure sodium lamp high luminous efficiency (200lm / w), improve the overall system brightness;
5, the overall life is extended, low-pressure sodium lamp can reach 20000h, metal halide lamp can reach 18000h, effectively reducing system maintenance costs;
6, electronic ballast has a number of intelligent protection, open circuit protection, short circuit protection, 160V-260V constant power output, power factor 98% or more, effectively reducing the system input current and reactive power loss;
7. Energy saving up to 40-50% with the existing high pressure sodium lamp under the condition of equal brightness;
8. Compared with the existing high-pressure sodium lamp, the color temperature and color rendering of the light are improved, and the lighting quality of the light is improved.
