Does the LED light save power than the general light source?
LED lampSmall size: LED is basically a small chip is encapsulated in epoxy resin, so it is very small, very light. Low power consumption: LED power consumption is very low, generally the working voltage of LED is 2-3.6V. working current is 0.02-0.03A. it means that its power consumption is less than 0.1W.Long service life: under proper current and voltage, the service life of LED can be up to 100 thousand hoursHigh brightness, low heat, environmental protection: LED is made of non-toxic material, unlike fluorescent lamp containing mercury will cause pollution, while LED can also be recycled
But if the white LED for lighting, not only high light efficiency, and long service life (more than 10000 hours of continuous work), almost no maintenance. At present, the German company Hella LED developed using white light aircraft reading a street lamp; the Australian capital Canberra has used the white LED lighting lamp; city traffic Management China is also the place of the early white LED traffic lights. Foresee in the near future, the white LED will enter the family to replace the existing.LED light source lamp with low voltage power supply, low energy consumption, strong applicability, high stability, fast response time, no pollution to environment, such as color light. Although the price is compared with the existing lighting equipment is expensive, it will inevitably replace the existing lighting devices.
Durable: the LED is fully encapsulated in epoxy. It is stronger than the bulb and fluorescent tube. There is no loose part in the lamp body. These features make the LED easy to damageHigh brightness, energy saving, high efficiency, fast reaction speed, good shock resistance, long service life. In order to illustrate the characteristics of white LED, look at the light source used at present condition. Incandescent lamp and halogen lamp, the light efficiency is 12 ~ 24 LM / W; light efficiency of fluorescent lamps and HID lamps the 50 to 120 lumens / watt. On LED: in 1998, light white LED is only 5 LM / W, in 1999 has reached 15 LM / W, this index is similar to general household incandescent lamps, and in 2000, light efficiency of white LED has reached 25 lumens per watt. This indicator and the tungsten halogen lamp is nearly.2005 years, LED luminous efficiency of up to 50 LM / W, 2010, the optical efficiency of LED reached more than 100 lumens / watt. White LED working current reaches. Lighting AMP level thus the development of white LED writer, will become possible.
