Lighting LED will be super backlit LED

The design of light environment in Beijing City Tsinghua planning institute director Rong Haolei said, in 2006, the LED application is less than 5%; in recent years, with the LED product technology matures and the prices of the products began to gradually decline, LED applied in engineering project, such as the Beijing Ocean Museum, Chinese National Museum, Guangzhou Asian Games, application LED lighting showing explosive growth. According to statistics, by 2010, the proportion of LED products using all lighting has exceeded 56%. Long track LED lighting industry shuiqingmuhua research director Zhou Yanwu analysis said that the application of LED is divided into three categories, one is the general lighting, is a kind of mobile phone and LED on TV, there is a class is the lowest one, namely billboard. Domestic enterprises belong to the last category. It is understood that the technical threshold of LED general lighting is very high, the world's only five companies can do, and are concentrated in the United States and Japan, South Korea and Taiwan, China, the gap between enterprises.

However, it is reported that LED is still the main backlight applications. DisplaySearch according to the published LED market forecast that LED lighting demand according to the amount of calculation, and has almost LED backlight, said a senior analyst at LeoLiu LED.DisplaySearchTaiwan LED in 2014 over the backlight, in 2011 LED lighting demand, LED 13 billion 529 million, LED backlight is 45 billion 969 million, the gap between the two is about 3.4 times. And in 2014, the demand for lighting LED and backlight LED will reach 58 billion 558 million and 50 billion 643 million, lighting LED market demand will officially go beyond the backlight LED. It is understood that the lighting LED needs more than the cause of the backlight LED, mainly the gradual popularization of LED lighting, coupled with the reduction of the number of LED used in each LCD panel backlight board. LCD TVs and LCD monitors, such as the use of large-size LCD panel products, is currently the driving force of the backlight LED market. Due to the improvement of LED brightness and product cost reduction and other factors, the number of LED equipped with these products will be less and less. In the device of large size LCD panel, the LED backlight has popularized stage, so even if the number of LED of each product is used to reduce the number of products, but is still increasing, so the whole market demand continues to expand in the LED. However, after the popularity of LED backlight to a certain extent, it is difficult to rely on the increase in the number of products to make up for the decline in the amount of LED backlight usage, so LED demand will gradually slow down. DisplaySearch predicts that backlight LED demand will reach its highest point in 2013, and then gradually reduced. DisplaySearch believes that the popularity of LED lighting will continue for some time, so demand will continue to increase. It is understood that in 2011 the proportion of LED lighting products in all lighting accounted for only 1.9%. Even in 2014, lighting LED needs to go beyond the backlight LED, but its proportion also accounts for only 9.3% of the lighting market, so there is still a lot of room for future growth.

Held in San Diego city in California in the United States "2011 LEDs conference", the U.S. Department of energy (DOE) lighting program director Jim Brodrick said the lights lighting and lighting slot frozen LED used in embedded downlight lighting, outdoor area lighting, 2x2 feet are very perfect, but the application of LED replacement lamps and concave round the skylight in the small, containing only a modified lamp bulb line performance is not so ideal. But. Straight line 4 feet LED lamp has been gradually improved, close to the efficiency of the fluorescent lamp, but the directional light output and distribution of LED is still not as good as the fluorescent light into the whole cylinder.

Zhou Yanwu said, LED universal lighting technology is the world's most powerful and occupy a monopoly of the United States Cree, Chinese LED companies can only forward to buy LED particles assembled. Zhou Yanwu also said that the domestic LED companies are good at low-end industries, there has been a serious excess capacity situation, the performance of listed companies is bound to be affected. Insiders said that the domestic LED enterprises small scale, backward technology, local governments to develop the industry, have carried out a huge financial subsidies. And if out of government support, the financial data of these listed companies will be very ugly.
