LED light source technology is maturing, long-term market barriers become smaller1

According to '2013- According to the analysis report of China's LED lighting industry market prospect and investment strategic planning in 2017, LED lighting market has always been considered as an important and promising application of LED. Overall, the macro environment is very beneficial to the development of LED lighting applications, mainly as follows: 1) Energy conservation and emission reduction has become a topic of concern and has been actively promoted; 2) Traditional light source technology grows slowly and faces development bottleneck. 3) The progress and cost of LED lighting technology are continuously decreasing, and the long-term market obstacles are no longer large. Data show that in 2009, the number of LED street lamps was about 2. 5 million, with a penetration rate of 1. In 4. 5 million, the number of LED street lamps reached, with a penetration rate of more than 2. The report predicts that the LED street lamp market will show rapid growth after 2010, with a compound growth rate of 97. 2009 from 2013 to. 75, by 2013, the LED street lamp market reached 21. $5. 9 billion. According to the analysis of the LED lighting industry research group of forward-looking Network, China's LED street lamp market will maintain sustained growth driven by the 10-city-lamp policy, and the scale of China's LED street lamp market is expected to reach 86 by 2013. 6. 3 billion yuan, accounting for about of the market, has become one of the important LED street lamp markets. With the continuous development of the industry, the breakthrough of technology and the vigorous promotion of application, the luminous efficiency of LED is also continuously improving and the price is continuously falling. The emergence of the new combined die also allows a single LED tube (Module)The power of is continuously increasing. Through the continuous efforts of the industry, the breakthrough of new optical design, the development of new lamps, and the single product situation are expected to be further reversed. The improvement of control software also makes LED lighting more convenient. These gradual changes all reflect the broad prospect of LED in lighting application. LED ceiling lamp is called the fourth generation light source and has the characteristics of energy saving, environmental protection, safety, long service life, low power consumption, low heat, high brightness, waterproof, miniature, shockproof, easy dimming, light beam concentration, simple maintenance, etc. can be widely used in various fields such as indication, display, decoration, backlight, general lighting, etc. Advantages of LED: high electro-optic conversion efficiency (Close to 100), Green environmental protection, long life (Up to 100 thousand hours)Low working voltage (About 3 V) Repeated switching has no loss of service life, small volume, less heat generation, high brightness, firmness and durability, easy dimming, various colors, stable beam concentration and no delay in starting.
