The LED lamp and promote vegetable production, let the miners safer

Fudan University Chinese lighting engineering department for a few bits of undergraduate climate catastrophe and how to improve the miners safety issues, proposed the use of LED lamp, LED lamp promote vegetable production made to miners more secure ad hoc, declaration and implementation of the national undergraduate innovation plan, Fudan University students winter vacation social practice project. It is understood that Fudan students of "solar energy LED lamps inquiry" in the field of plant light utility project, a comparative study of the fluorescent lamp and LED lamp in the promotion of vegetable production effect. To this end, they bought the lamps on the basis of investigation, started an experimental program for 2 months, with photographs obtained LED lamps in promoting the growth of vegetables more than the fluorescent lamp, but also has the power shortage of higher cost, small place, and put forward the solutions. If this technology once mature into production, can use sunlight on a sunny day, rainy days using artificial light light to promote vegetable production, compared with open-air cultivation, can ensure that more than 10 times the yield, the future will have no pesticides, no washing of the good qualities. At the same time, Fudan light source and lighting Engineering Department of several students in the practice of the project found that the new LED lamp used as miner's lamp will solve the problem of mining. The LED lamp has the advantages of small volume, low calorific value (no heat radiation), small power consumption (low voltage, low current, long service life (start) theory of life more than 100 thousand h), fast response (several nanoseconds), resistance to vibration and impact and no pollution etc.. Practice project found that LED lights also exist some problems to be solved. First, as a cold light source LED lamp, which is more sensitive to the temperature of the semiconductor, the temperature change will affect the service life of the lamp. Second color temperature control is not clear. Color temperature will affect the brightness and temperature, and the color temperature is too high on the degree of damage to human eyes.
