The LED lamp is the 3rd generation of new electricity photosource.

The LED lamp will occupy half photosource market in the world in 2020.

The LED lamp has many advantages which most of incandescent lamps and the fluorescent lamps dont have:
1. Last more than 50, 000 hours.
2. No rupture or break, anti-vibration, safer.
3. Saving electricity, much higher efficiency than incandescent lamp, low heat.
4. Not glitter like fluorescent lamp.
5. Available in different colors.
6. Easy to transport, carry and store.
The LED lamp is suitable for street, corridor, warehouse, tunnel, cave, no electricity places and so on.

Nowadays the luminous efficiency of white LED lamp is approximately 60 LM/W (lumen/watt), and the standard 60W-100W incandescents is 17 LM/W, thus LED is 3.5 times of incandescent.

While the luminous efficiency of low power incandescent lamp is lower, below 10w, the luminous efficiency of LED lamp is approximately 7 times of it, then illumination of 1W LED lamp is equal to the 7W incandescent lamp, namely it can save six-sevenths electricity.

Although the price of current LED product lamp is about 10 -20 times of incandescent lamp with the same degree of illumination, electricity saving and long lasting may counterbalance its price, generally it is economic and saves the energy!

Also, due to low heat, it can help air conditioner save electricity as 3 times as it does itself.
