Energy conservation and environmental protection will be the mainstream of future social industrial development, and semiconductor lighting is one of the important forces. At the same brightness, the power consumption of semiconductor lamps is only one-tenth that of incandescent lamps. As long as one-third of incandescent lamps are replaced by semiconductor lamps, the country can save nearly 100 billion kWh of electricity every year, equivalent to a Three Gorges. The amount of electricity generated by the project.
At present, China's energy crisis is increasingly severe. In 2006, the country's power generation reached 2,755.7 billion kWh, and lighting used more than 330 billion kWh, accounting for 12%. At the same time, road lighting accounted for 25%-30% of the total lighting power. The annual power consumption reaches 100 billion kWh, and the energy saving potential is huge. Jiangsu is a province with large energy consumption and a small province with energy resources. The population density is high. The development of energy-saving and environmentally-friendly semiconductor lighting industry is of great significance to Jiangsu's construction of a conservation-oriented society.
At present, the most used road lighting is high-pressure sodium lamp, which has short life, poor color rendering and high power consumption. It is urgently needed to replace the semiconductor lighting technology with energy saving, environmental protection and long life. With the maturity of semiconductor lighting technology, the efficiency of high-power semiconductor light source has reached 80lm/W, and the energy-saving transformation of urban street lighting has become possible. The application of semiconductor light source in road lighting has become a hot spot in the semiconductor lighting industry in recent years. The promotion of semiconductor lighting technology in the field of road lighting will effectively reduce electricity bills, reduce cable laying costs, reduce maintenance costs, improve road travel safety, and help governments at all levels to complete energy conservation and emission reduction targets.
Nanjing Handerson Technology Co., Ltd. has been committed to the research and development and production of semiconductor road lighting. According to the person in charge of the company, according to the current test results, Henderson semiconductor street lamps save more than 60% of electricity compared with traditional high-pressure sodium lamps. At the same time, high-power semiconductor light sources can be used normally for 10 years without replacement, while traditional high-pressure sodium lamps average 1 to 1.5. It will be replaced once a year, and the use of semiconductor light sources can greatly reduce maintenance costs. If the current total number of street lamps in Nanjing is 200,000 baht and the average daily lighting is 10 hours, the annual electricity bill will be around 220 million yuan. After the change to semiconductor street lamps, the annual electricity saving will exceed 130 million yuan, plus the saved cables and Maintenance costs will be more than 150 million yuan per year. The economic and social benefits will be huge. Semiconductor lighting will usher in an explosive growth period in the urban road lighting market.
Semiconductor lighting will become a new direction for energy-saving renovation of urban road lighting.
