   First, the two poles of energy-saving lamps are ordinary tungsten wire. Tungsten wire power fever, you can emit electrons. In the lamp on both sides with a relatively high voltage, the formation of electric fields, these electrons will be accelerated in the lamp, the formation of a certain speed and energy of the electronic flow. The lamp is pumped into a vacuum, filled with mercury, that is  what we call the mercury.
   Second, what are the advantages of LED lights
   1, energy saving. White LED energy consumption is only 1/10 of incandescent, energy-saving lamps 1/4.
   2, longevity. Life of up to 100,000 hours or more, the ordinary family lighting can be described as "once and for all".
   3, can work in high speed state. Energy-saving lamps if the frequent start or turn off the filament will be black quickly broken.
   4, solid-state packaging, are cold light source type. So it is very convenient to transport and install, can be installed in any miniature and closed equipment, not afraid of vibration, basically do not need to consider cooling.
   5, LED technology is changing with each passing day, its luminous efficiency is striking breakthrough, the price is also constantly reduced. A white LED into the family's era is coming quickly.
   6, environmental protection, no mercury harmful substances.LED lamp assembly parts can be very easy to disassemble, no manufacturers can be recovered through other people recycling.
   To sum up:Obviously, as long as the cost of LED lights with the continuous improvement of leading technology to reduce energy-saving lamps and incandescent lamps will be replaced by LED lights the current state more and more attention to lighting energy and environmental issues, has been vigorously promoting the use of LED lights. In particular, the Government to rebuild the street project is the first LED lights, some time ago, a primary school in Jiangsu as long as three lights, the school was designated LED lights can be seen instead of LED lights energy-saving lamps, incandescent lamp momentum.http://www.outedsionbulb.com/
