LED light,energy saving,environmental light

July 16, 2012 - PRLog -- What is LED? LED is the short name of Light Emitting Diode.
When Edison invent the filament lamp, life change a lot.light is so important to people’s life,so as the electricity.
The development of light experienced filament lamp,then energy saving lamp, and now, LED come into our life.
The revolution of light makes our life better and better,more environmental and friendly.
Energy saving lamp is more popular than LED nowadays, as its name,energy saving,but,LED can save energy as well, and there are more advantages than energy saving lamp.
First,under the condition of same luminance,for example, 3W LED consume 1KWH can last 333 hours,filament lamp can last 17 hours，energy saving lamp can last 200 hours.so, you can know the excellence of LED light.
LED light contain less UV and IR,produce less radiation. There is no mercury and xenon,it is good for recycling.and other normal lamp contain mercury and plumbum and so on.
LED is DC driving ,there is no stroboflash,it can protect the eyesight well. Other normal lamp is AC driving,then there will be stroboflash.
Second,the safe index is high,because it just need lower voltage and current .then it is a good choice for some dangerous place ,such as mine field.it can use battery and solar energy to charge,then ,it is a good option for remote area and wild lighting.
LED technic is improving,some heat dissipation problem ,cost price,lower color rending index problem need to be solve.
But for the present,LED can be use for spotlight and droplight. We can belive that,LED will overtake energy saving lamp in the future.
