In many families, institutions, government and industrial applications, high brightness (HB) white LED (light emitting diodes) are rapidly replacing incandescent lamps. In the past year, the white LED lighting systems for lighting applications in total account for more than 50% more than the final color LED applications, color LED lighting applications is mainly affected by the beauty of color demand-driven. The new white LED illumination growth driver is fairly simple: The lower the energy consumption leading to lower tariffs. In many cases, LED higher efficiency can reduce power consumption by up to 88%. They also greatly reduce the opportunities for lighting and power generation and transmission of electricity caused by carbon dioxide emissions. According to research firm Strategies Unlimited, 2012, the total high-brightness white LED lighting market is expected to more than 5 billion U.S. dollars, corresponding to 2009 to 2012 of 28% compound annual growth rate (CAGR). This is just the beginning, because the LED luminous efficiency continues to accelerate the commercial / residential lighting market from incandescent, fluorescent and high pressure sodium to high-brightness white LED, while changing, LED or even from a commercial point of view has become more cost-effectiveness. According to some calculations, shifted from traditional incandescent and fluorescent lighting LED current global total energy consumption could save up to 10%. As people speed up efforts to lower the total power generation of carbon dioxide emissions, global lighting energy demand by 10% of the potential of such changes played a great role. New York, were high-brightness LED lighting of the bridge New York, were high-brightness LED lighting of the bridge What factors support such a huge growth potential? First, the current generation of LED luminous efficiency 10 times higher than incandescent, fluorescent and HPS is (HPS) more than twice, thus greatly reducing the necessary light output (measured in lumens) of electricity needed. With the further development of LED, which depend on the efficiency of the power light will continue to increase, and is expected to double within the next few years. Second, very concerned about the environment in a world, LED lighting does not need treatment, contact and remove the toxic mercury fluorescent lamps in common steam. Today, most residential lighting systems for cold cathode fluorescent lamp (CCFL) with up to 5mg of mercury, while the larger lamp contains mercury is much more! Third, the incandescent lamp with 1,000 hours each to replace, and sustainable use of fluorescent lamps up to 10,000 hours, compared, LED life span of more than 100,000 hours. In most applications, this allows LED permanently embedded into the final application, without attachment. Examples include commercial and residential indoor and outdoor lighting, such as street lamps, indoor and outdoor industrial lighting and power plants and refineries such as adverse environment such as lighting. Some applications (such as refinery) 24-hour operation, LED will continue to use up to 11 years, which means that they will need replacing. In addition, LED lights than other types of several small and flat digital level, can create a very flat form factor, so they can be permanently placed in the internal and external applications. LED's small size also makes LED into the reflector housing can make more precise and thus more efficient to focus light. White LED provides pure "full spectrum" white light, there is no gap in the chromatography, which require reliable visual acuity tasks, we can very easily see clearly. For example, view the color wire, read the color mark or distinguish between water vapor and smoke caused by fire. In contrast, high pressure sodium orange light environment to accomplish the same task may be difficult, because in this lighting environment can not accurately distinguish colors. With the human eye to detect, compared to the changes, LED also to a much faster rate of dimming and on / off, which greatly reduces the power consumption. LED lighting can be dimmed or off, until they are needed, and then immediately turned to maximum intensity, and fluorescent or high pressure sodium lamps take up to 30 seconds or longer to reach maximum intensity. However, the lighting system, one of the biggest challenges facing designers is how to optimize all the benefits of the latest generation of LED. Because LED usually an accurate and efficient DC current source and a dimming method, the LED driver IC must be designed in a variety of applications to meet those needs. Power solution must be efficient, robust, very compact and cost-effective. Can be shown, on the drive light from incandescent, fluorescent and high pressure sodium lighting to LED array change, the fastest-growing application will appear in the common interior / exterior lighting applications, because in such applications, the power to save the return is the largest. Such as small size, long life, low power consumption, easy to transfer the benefits of light and fast turn time has accelerated the high-brightness LED lighting in the industrial and residential lighting applications, and many have been adopted. LED's long life and small size makes the introduction of the new configuration of various applications possible, such applications include front in the refrigerator white LED lighting arrays, as well as illuminate the entire campus more complex systems.
