The total size of LED market in 2018 will reach 25. 9 billion US dollars, of which LED general lighting market share is 57. Other businesses in the LED market include signage, Automotive Lighting, mobile devices, display backlights and monitors. In the commercial and residential markets, Universal Lighting LED applications will continue to gain traction and further accelerate growth. Commercial application of high lumen LED lighting system will show significant growth. At present, household LED lighting is still too expensive for consumers. Based on the long-term benefits of LED lighting, energy-saving and environment-friendly characteristics and related tax relief measures, the use of LED lighting in the commercial field will be greatly increased, these commercial areas cover parking lots, office buildings, factory facilities and warehouses. LED lamps will not only replace high pressure sodium lamps, halogen lamps and incandescent lamps, but will even replace CFL and fluorescent lamps in some fields. It is estimated that LED Commercial Lighting grew rapidly and was widely used in 2011, while LED home lighting did not begin to rise until 2012. It is not surprising that LED lighting is first used in industrial and commercial applications, because these applications require long-term high-intensity lighting, and the economic return of saving electricity is relatively short-term. Secondly, the long life of LED lamps can reduce the replacement cost of bulbs, including the price of bulbs themselves and the replacement cost of labor, while in some applications such as high-shed lighting, the installation cost of labor is very high. The main driving force for the high growth of LED lighting is that compared with traditional lighting, LED lighting can significantly reduce energy consumption. Compared with incandescent lamps, LED lighting can save of electricity under the same level of lighting. LED lighting fixtures do not contain any toxic substances for management and treatment, while CFL uses toxic mercury gas for operation. After that, LED can achieve a new low profile that other technologies cannot match. Another factor promoting the replacement of home LED lighting is the fact that 40W and 60W incandescent lamps used by most American households are prohibited from being manufactured or imported in the United States (Of course, it can still be purchased) In 2012, 70W and 100W incandescent lamps were also eliminated one after another. Therefore, under the same lumen output, the solid-state LED equivalent product with only 1/8 energy consumption is welcomed by the real world.
