When natural disasters such as earthquakes occur, emergency lighting is an essential equipment for escape and disaster relief. However, such emergency lighting fixtures often have a defect, and the lighting time is short, usually only one hour. A national high-tech enterprise in Ningbo National High-tech Zone recently developed the first energy-saving requirement in China that can meet the energy-saving requirements in daily use, and provide sufficient illumination and lighting time in case of emergency power outage, for escape and rescue of property and Efficient emergency LED luminaires for power system repair. Not long ago, this “Indoor LED Emergency Lighting Application Integration Technology Development and Demonstration†project received a special fund of 3.15 million yuan for the National “863 Programâ€.
According to reports, in the event of an emergency in the event of an earthquake emergency, the previous emergency is the fluorescent energy-saving lamp. Although this lamp is much less than the power consumption of the incandescent lamp, it can only rely on the battery as the only electric energy. Next, he was able to maintain the current for only one hour. The use of LED lamps for emergency use, its working time is at least 3 hours, the reason for the increase in power supply time is the energy saving of LED lights.
In the sample showroom of Shengpu Opto Semiconductors Co., Ltd. of Ningbo National High-tech Zone, the staff gave an experiment to the reporter. On one plate, an incandescent lamp, a fluorescent energy-saving lamp and an LED lamp are installed. At the same time, the luminous flux of the incandescent lamp (ie, the brightness of the light) is 200 lm, the luminous flux of the fluorescent energy-saving lamp is 220 lm, and the LED lamp is 260 lm, however, The incandescent lamp has a power of 25W, the fluorescent energy-saving lamp has a power of 5W, and the LED lamp has a power of only 3W. This means that the LED lamp emits the brightest light, but the energy consumption is the lowest.
General Manager Zhang Niu said that in working conditions, LED lights are 80% more energy efficient than incandescent lamps and 30% to 60% more energy efficient than fluorescent energy-saving lamps. Therefore, when LED lights are applied to emergency lighting, its working time is greatly extended.
The author has learned that the current Cuiwei Building in Beijing and the Tokyo Commercial Building in Japan have all used LED emergency fluorescent lamps for the enhanced spectrum. In the Wenchuan earthquake and snowstorms in previous years, the portable LED emergency lights developed and produced by them played a significant role in disaster relief lighting. This portable LED emergency light is powered by hand and is very easy to use. It can be used for 15 minutes by shaking the handle for 1 minute.
However, Zhang Sun said frankly that LED lights currently have less than 10% market share, and its high price is a “blocker†that affects its entry into ordinary people’s homes. Few families in China use such expensive LED lights in the same performance. Next, the price of LED lights is 3 to 6 times that of ordinary energy-saving lamps. However, Lin Sheng said that LED lights have the advantage of energy saving and emission reduction, and its sales will enter a big development stage in the next three to five years. "After all, the service life of LED lights can reach 30,000 hours. In addition to the environmental protection of the manufacturing process, it is more obvious in the process of energy conservation and environmental protection during use." Zhang Niu gave the reporter an account: led fluorescent lamp The annual target of industrialization is 1 million calculations, saving 2.1 billion kWh of electricity per year, saving 8.4 million tons of water, saving 840,000 tons of coal, reducing carbon dust emissions by 570,000 tons, and reducing carbon dioxide emissions by 2.1 million tons. .
