Do not lose? Campus LED lights 5 years nearly 8 million

CNR network news, the world did not make the sale of light? Yes Recently, all the lights on the campus of Dalian University of technology are new, greatly increase the brightness. The facelift, the total replacement of the school more than 41000 lamps, not only did not spend a penny school, a year down 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 an account: the school last year, 2 million 280 thousand yuan lighting electricity, lighting maintenance costs of $300 thousand, a total cost of 2 million 580 thousand yuan. Replaced by LED energy-saving lamps, a year of electricity is only about 1 million, lighting maintenance costs can be basically eliminated within five years, such a calculation, save nearly a year of 1 million 600 thousand, the year is 8 million.

LED energy-saving lamps energy efficiency in the end how? Professor Zou Nianyu, director of the Institute of photonics, Dalian Institute of industry and another account: she said, LED is the abbreviation of Light-Emitting Diode. LED light source is the light source of the light emitting diode, is a new revolution in lighting technology since Edison invented the incandescent lamp.

LED energy-saving lamps with incandescent lamp and other lamps difficult to shoulder the advantages of: longer life. Ordinary incandescent lamp life is only one thousand hours, ordinary energy-saving lamp is only eight thousand hours. Under normal circumstances, the use of LED lights, the life expectancy of fifty thousand hours. This greatly reduces the maintenance costs of lamps and lanterns, to avoid the pain of frequent replacement. Electricity saving. LED lamp power consumption is very low, in the case of the same lighting effect, the use of 45 watt ordinary fluorescent lamp lighting effect is equivalent to only 15 Watt LED light source. Higher luminous efficiency. In the lighting industry, the use of lumens to describe how much light radiation energy. Incandescent light efficiency of about 20 lumens / watt, fluorescent lamp is 60 lumens / watt, while the LED lighting efficiency can reach up to 120 lumens / watt, and with the progress of technology will continue to improve. Better photochromic controllability. The luminous color and brightness of LED is variable, and can be adjusted according to the actual needs, so that the light environment can change with the needs. Higher safety factor. LED lamp is a cold light source, no heating, the use of direct current, voltage is small, the risk is small, the safety factor 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 health 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. Dalian Industrial University campus green lighting, not only to earn the light, but also earned a savings, environmental protection and health, is indeed the light do not lose.
