Overview of the fourth generation LED lamp
LED is called the fourth generation lighting source or green light source, with energy saving, environmental protection, long life, small size and so on. LED, as a new type of green light source, is bound to be the trend of future development. Review the history, human lighting technology has experienced four stages: the biggest disadvantage of incandescent lamp, fluorescent lamp, high pressure lamps and semiconductor lighting, incandescent lamp is a waste of energy, because most of it can be converted into electrical energy loss. The fluorescent lamp is a fluorescent lamp, it is more than incandescent lamp energy saving, but it has the stroboscopic damage to eyesight, and because mercury vapor will pollute the environment. LED combines the advantages of both, and to achieve a qualitative leap. First of all, it is very energy-efficient, more than 60% of the power saving fluorescent lamp, second, LED long life, up to 100 thousand hours (ordinary energy-saving lamps 8000-10000 hours). Third, it has no pollution. In addition to intelligent LED's' expertise'. LED, is the fourth generation of lighting devices after the invention of the electric light Edison. Today, LED will gradually replace the incandescent lamps and energy-saving lamps.

Advantages of LED fluorescent lamp
Green environmental protection: do not contain mercury and lead, mercury and other harmful elements, ordinary energy-saving lamps in the electronic ballast will produce electromagnetic interference.
Light efficiency is high: heat is small, 90% of electric energy can be converted into visible light, and the electric energy of ordinary incandescent light 80% can be converted into heat energy, and only 20% of electric energy can be converted into visible light.
The safety factor is high: the required voltage, the current is small, the calorific value is small, there is no safe hidden danger, can be used in the mine and other dangerous places,
High efficiency and energy saving: LED fluorescent lamp power consumption is 1/5 of the traditional fluorescent lamp, power saving up to 70%-80%.
Long life: the service life of up to eighty thousand hours, ordinary energy-saving lamp life ten thousand hours, ordinary incandescent lamp life one thousand hours.
Strong and reliable: LED fluorescent light itself is the use of pressure PC and aluminum is not the traditional glass, solid and reliable, more conducive to transport.
Protect eyesight: DC drive, no stroboscopic, do not use a long time to make glasses fatigue, ordinary light is AC drive, will inevitably produce stroboscopic.
Light health: there is no ultraviolet and infrared rays, no radiation, ordinary energy-saving lamps and incandescent light in the ultraviolet and infrared. Luster stable, not affected by age.

About the price of LED fluorescent lamp
The disadvantages of LED fluorescent lamp is the only high prices, but despite the current LED fluorescent lamp price is about ten of the fluorescent lamp, if the link to its service life, energy saving and no pollution, is still worthwhile. Because if and life is 5000 hours of fluorescent lamp, then life is 50 thousand hours of LED fluorescent lamp has been worth the price of 10 to buy, and in the meantime the savings of electricity is completely pure income. In some 24 hours of continuous work places, such as underground parking lot, 24 hours of overtime production factories and other places, energy saving is particularly important.
