Over the past 10 years, with the rapid development of the economy, China's energy crisis has become increasingly prominent. The energy shortage has become a bottleneck restricting our economic development. In particular, the shortage of fossil energy has brought us to modern industry and business and people's lives. Great impact. Therefore, for the entire country, in order to alleviate power shortages and reduce energy consumption, it is imperative to implement energy conservation and emission reduction in the lighting industry. According to experts, to improve traditional energy consumption, it is necessary to promote the development of green energy-saving lighting.
1. LED features:
LED energy-saving lamps save more than 90% of electricity, life is more than 10 times that of ordinary lamps, almost maintenance-free, there is no problem of frequent replacement of lamps, ballasts, starters, about 6 months to 1 two The annual savings can be exchanged for the cost. The green environment-friendly semiconductor light source has soft light and pure spectrum, which is beneficial to people's vision protection and health. The 6000K cold light source gives a visually cool feeling, which is conducive to concentration and improve work efficiency.
At present, the life of incandescent lamps is 1000 hours; the life of fluorescent lamps is 6000 hours; the life of LED lamps is 50000-100000 hours; under the same brightness conditions, energy saving is more than 80% than that of incandescent lamps, and 50% energy saving than fluorescent lamps. Chen Lianghui, an academician of the Chinese Academy of Engineering and a researcher at the Institute of Semiconductors, estimated: "As long as one-third of incandescent lamps are replaced with LED lights, the annual power consumption of 100 billion US dollars can be reduced, equivalent to the total power generation of the Three Gorges in a year.
2. Energy saving effect
The brightness of 10W LED energy-saving lamps is brighter than the traditional 40W fluorescent lamps. The 16WLED energy-saving lamps are brighter than the traditional 68W fluorescent lamps. The brightness of LED energy-saving lamps is especially softer and more acceptable. The service life is 50,000 hours -100,000 hours, the power supply voltage is AC85V-260V (AC), no starter and ballast are needed, the start-up is fast, the power is small, there is no stroboscopic, and it is not easy to visual fatigue. It is not only super energy saving but also more environmentally friendly. It is one of the key products developed by the national green energy-saving lighting project, and is currently the main product to replace the traditional fluorescent lamp.
3. Installation method
The installation of LED energy-saving lamps is very simple. When installing, the original fluorescent lamps are taken down and replaced with LED energy-saving lamps, and the original ballasts and starters are removed, so that the 220V AC mains can be directly added to the LED fluorescent lamps. .
Analysis of energy saving effect of engineering renovation
Before the renovation: an office building was originally installed with 2000 ordinary fluorescent tubes. The power of each fluorescent tube is 45W/H. The daily lighting time is 8 hours. The daily power consumption is 720KWH (45W*8*2000). KWH's electricity bill is 1 yuan, the daily electricity consumption is 720 yuan, calculated in 30 days a month, 21600 yuan, the annual electricity consumption is 259,200 yuan, the power consumption is large, the need for energy-saving renovation
After transformation:
We replaced the original 45W fluorescent tube with a 10W LED energy-saving lamp, the same 2000 LED energy-saving lamps, working 8 hours a day. From the perspective of energy saving, the daily power consumption is 160KW, just before the transformation. 22%, electricity costs only 160 yuan / day, 4800 yuan a month to calculate 30 days, the annual electricity consumption is only 57600 yuan.
10.1 Inch Laptop
Which is the most welcome kid laptop for entertainment and online learning? 10.1 inch laptop is the best choice.
