In many families, institutions, government and industrial applications, high brightness ( HB ) white LED ( light emitting diode ) is rapidly replacing the incandescent lamp. In the past year, white led lightings system in general lighting applications accounted for more than 50%, eventually more than color LED applications which is mainly affected by the color illuminating aesthetic demand driven. White LED lighting is driving force for samples reasons: low energy consumption leads to much lower electricity.
In many cases, LED higher efficiency may be reduced by as much as 88% power consumption. They also greatly reduced for lighting and power generation and transmission of electricity caused by carbon dioxide emissions. According to Strategies Unlimited’s research white led lightings market is expected to exceed $5 billion. This is just the beginning, because in the LED Panel Light luminous efficiency continuesly to accelerate the commercial / residential lighting market from an incandescent lamp, fluorescent lamp and high pressure sodium lamp to high-brightness, white LED change at the same time, LED is much more cost-effective.
By some estimates, incandescent and fluorescent lamps to LED lighting can make the current global energy savings of up to 10% traditinally. Along with the efforts to reduce the power generated by the total carbon dioxide emissions, global illumination reduces 10% ,which played a great role in promoting.
What factors support such a huge growth? First of all, the current generation of LED luminous efficiency is 10 times higher than incandescent lamps, fluorescent lamp and high pressure sodium ( HPS ) more than two times, which greatly reduces the required light output ( measured in lumens ). With the further development of LED, they rely on the power light emitting efficiency continually improved, but it’s expected in the next few years .
secondly, about environmental protection in the world, led lightings does not need treatment, exposure and removal of fluorescent lamp in the common toxic mercury vapor. Most of the residential lighting system for cold cathode fluorescent lamp ( CCFL ) containing up to 5mg of mercury, and the greater light containing mercury will be much more!
In third, the incandescent lamp every 1000 hours will be replaced by the fluorescent lamp, and sustainable. in contrast, LED’s life over 100000 hours. In most applications, this allows the LED permanently embedded into the final application.
