The LED industry in the past two years can be described as internal and external problems. It is rumored that many small companies have been dying or even closed down. However, there seems to be good news recently. After the market shouted that it is expected to enter the LED lighting generation in the second half of 2013, the academic community has also responded. Xiao Hongqing, a professor at National Taiwan University of Science and Technology and executive director of the Lighting Society, said that the performance of the product's luminous efficiency (light efficiency) will be the focus of accelerated development of LED lighting, and the reasonable threshold of light efficiency falls on LED chips reaching 170 lm / W (lumens / watt).
Xiao Hong pointed out that Cree, Nichia and Philips have the highest luminous efficiency of 240 ~ 260 lm / W, and Cree also claims that 180lm / W products can be mass-produced from the beginning of this year, so it is estimated that the overall market will be this year. Reaching this level in August, the LED industry is expected to break away from over-reliance on the backlight panel industry, enter stable lighting demand, and enter the era of true LED lighting.
He said that many market products are still compared with each other in terms of luminous flux. In fact, light efficiency is the focus of accelerated development of LED lighting. When the LED chip light efficiency reaches 170 lm / W, the light efficiency of the LED lighting light engine module system is about 125 lm / W has exceeded the luminous efficiency of T5 fluorescent lamps, so if LED lighting is to be successfully developed, the reasonable threshold of LED chip luminous efficiency is 170 lm / W.
In response to market conditions, Xiao Hongqing said that the current mass production level of most products in the market is 100 lm / W, and except for the international manufacturers Cree, Nichia, and Philips, the highest luminous efficiency is 240 ~ 260 lm / W. The laboratory LED chip light efficiency has also reached 230 lm / W, and Jingdian (2448) has the same level, but it is estimated that it will take more than half a year for the entire market to achieve 170lm / W products in mass production. It is expected to break away from over-reliance on the backlight panel industry, enter stable lighting demand, and enter the era of real LED lighting.
In 2013, the global LED lighting market increased by 30%
With the continued decline in LED lighting prices and the rapid expansion of the number of scales, Lin Zhixun, leader of the Energy Research Group of the Industrial Economics and Trends Research Center of the Industrial Technology Research Institute, pointed out that the global LED lighting market should maintain a growth rate of 30% in 2013 and should be within 2020 The global LED lighting output value is 65.8 billion US dollars.
Lin Zhixun said that the key market for the future development of LED lighting will still be in the mainland, Europe, and the United States, but non-tariff trade barriers such as relevant standards, specifications, energy efficiency requirements, and local protectionism must also be noted. The Asian region is currently the main global LED lighting sales area and the largest application area for LED lighting, with a market share of 40% in 2011. Mainly due to government support, high economic growth, and frequent construction activities. Among them, the Japanese market is the most active in promoting LED lighting applications. In 2011, the size of the Japanese LED replacement lighting market reached US $ 952 million, and the estimated market size in 2012 reached US $ 120.3 million.
In terms of individual application markets, the penetration rate of LED lighting in the architectural lighting market was as high as 56% in 2012, but it has also slowed down due to the maturity of the market. Outdoor lighting is benefiting from the government's creation of market demand, which has led to the slow growth of LED lighting applications. In 2012, the penetration rate of LED lighting in industrial lighting applications was only about 6%.
The application of LED lighting in commercial lighting has gradually shifted from the early functional lighting to the main lighting application. Because of the high turnover rate and long-term use of commercial lighting, the penetration rate of LED lighting has grown synchronously with the market size. LED lighting in 2012 The penetration rate of the commercial lighting market has reached 15%.
Residential is the world's largest application market for lighting. LED lighting is rapidly entering the residential lighting market with bulbs to replace traditional bulbs. However, due to the high sensitivity of consumers to prices, LED lighting penetration in the residential lighting market in 2012 was about 13% , Still to be improved.
Office lighting is based on energy saving. LED lighting mainly replaces traditional fluorescent lamps and enters the office lighting market. However, LED lamps must also face the price competition of T5 fluorescent lamps, so the penetration rate in 2012 is only about 11%, there is also much room for growth.
