Street lights usher in the tide of LED light sources
Recently, with the deepening of the construction of smart cities, many cities across the country have launched the "multi-in-one" pilot, making street lights grab the headlines of the lighting industry and becoming one of the most concerned lighting fixtures in all sectors of society. In the past ten years, street lamps that have witnessed the important development of modern lighting history in China have undergone tremendous changes in form, function, and socio-economic benefits.
Below, China Lighting Network takes everyone to review the evolution of Chinese street lights in the past ten years, and to explore the technological value it brings to the innovative development of China's lighting industry.
Awareness consciousness awakens, street lights usher in the tide of LED light sources to replace
In the past, high-pressure sodium lamps have always been used as the main light source of street lamps due to their high power and high brightness. However, due to shortcomings such as high energy consumption and short life of high-pressure sodium lamps, municipalities have brought a lot of burden on management funds. In addition, problems such as poor light energy utilization and low light efficiency have become increasingly prominent, which directly affects traffic participants on the road. Visual experience.
From the end of the 2000s to the beginning of the 2010s, driven by national policies such as “energy saving and emission reduction”, “thousands of thousands of miles”, and “trillions of lamps”, the tide of LED light source replacement has also come. High-power street lamps in the lighting industry have naturally become an important member of this trend.
Relevant statistics show that compared with street lights with high-pressure sodium lamp light source of the same power, LED street lights can save 40% -80% of energy consumption; in terms of light color and road lighting effect, the color rendering index of LED street lights with cold color temperature is better than that of warm color temperature The traditional light source sodium lamp light source street lights should be 45 ~ 55 tall. In addition, LED light sources are more likely to form effective light, allowing traffic participants to see the road conditions more clearly. In terms of light source service life, compared with high pressure sodium lights 1 ~ 2 years, LED light sources can Used for more than 10 years, making it a perfect substitute for high-pressure sodium lamps in road lighting.
However, the LED street lamp seemed perfect and infinite, but when it was first promoted, many municipal engineering contractors were discouraged for no reason. At the time, at the price, a set of high-pressure sodium lamp street lamp heads About 1200 ~ 1500 yuan, and the price of a set of LED street lamp head is about 2000 ~ 5000 yuan.
Under this application bottleneck, a cooperation model called Energy Management Contracting, or EMC for short, has become popular in the procurement of LED street lights. Following the principle that the longer the LED lighting time, the more energy-saving benefits, and the more obvious the return on investment, the government provides guarantees. LED street lamp manufacturers benefit from energy-saving benefits. Energy-consuming units and energy-saving service companies also follow the agreed ratio. Share energy-saving benefits together, and municipal engineering contractors can achieve zero or less investment in this model, thereby reducing the direct economic burden of purchasing LED street lights.
In addition, LED street lamp manufacturers represented by QinShang Optoelectronics also flexibly combine the EMC model with other business models. The production companies not only serve as product and service providers, but also take into account the bridge between financial institutions and customers. Users and financial institutions have realized the maximization of benefits and minimization of risks in the new installation and replacement of LED street lights, forming a win-win situation for the three parties.
