Only earn not lose? Campus facelift LED lamp 5 years, nearly 8 million

CNR network news, the world has earned not lose the sale? Yes Recently, all the lamps in Dalian Industrial University campus have greatly increased the brightness of light take on an altogether new aspect. The "Huanzhuang", the total replacement of 41000 a plurality of lamps, can not spend a penny a year of school, it will save a lot of money.

According to the Dalian Industrial University General Office Director Liu Zhenguo introduced, all the school replaced is the LED energy-saving lamps, these lamps provide lighting enterprises by free, the school does not need to spend extra money, as long as the contract period (5 years) in the annual electricity savings to pay a portion of the enterprise is enough. He gave calculations: last year the school lighting electricity 2 million 280 thousand yuan, lamp maintenance costs 300 thousand yuan, a total cost of 2 million 580 thousand yuan. A LED energy saving lamp, a year of electricity is only about 1 million, the lamp maintenance fee within five years can be avoided, such a calculation, annual savings of nearly 1 million 600 thousand, 5 years is 8 million.

The effect of energy saving LED energy-saving lamp in the end? Dalian Institute of Photonics Research Institute Professor Zou Nianyu. Another account: she said, LED Light-Emitting is short for Diode. LED light source is a light emitting diode as light source light, is another new revolution since Edison invented the incandescent lighting technology.

LED energy-saving lamp has the advantages of incandescent lamp and other lamps to par: longer life. Ordinary incandescent lamp life of only one thousand hours, ordinary energy-saving lamps only eight thousand hours. Use normally LED lights, the average life of fifty thousand hours. This greatly reduces the maintenance cost of the lamp, to avoid frequent replacement of the pain. Use less electricity. The LED lamp power consumption is very low, in the same lighting effect, the lighting effect using common fluorescent lamp 45 watt equivalent to only 15 Watt LED light source. High light efficiency. In the lighting industry, used to describe how much radiation lamp lumens of light energy. Incandescent light efficiency is about 20 lumens / watt, fluorescent lamp is 60 LM / W, and LED lighting efficiency can reach 120 LM / W, and with the advancement of technology will continue to improve. Color better controllability. Light color and brightness of LED is variable and can be adjusted according to actual needs, so that the light environment can change with the needs of. A higher safety factor. The LED lamp is cold light, no heat, using a direct current voltage, small, small risk, safety coefficient is higher. More green. LED lamp, no harmful metal mercury, non-toxic, no infrared and ultraviolet radiation, will not produce electromagnetic interference, shock resistance, impact resistance, not easy to break, and then use Recyclable. More conducive to healthy lighting. After the circuit design and reasonable optical design, LED lamps can be no flicker, no glare, light more soft, conducive to the protection of eyesight, and make life more comfortable and healthy learning environment. Campus green lighting Dalian Industrial University, earned not only is "light", but also to make the saving, environmental protection and health, is indeed the light earned not lose.
