In the future, energy-saving and environmental protection and consumer personalization and other trends, the development of LED lighting applications has attracted much attention. According to the IEK research of the Industrial Technology Research Institute of Taiwan, the global LED lighting market in 2007 is about 330 million US dollars, which belongs to a small-scale basic market. However, as LED costs gradually decrease and efficiency increases, the speed of commercialization of LED lighting will Accelerate, it is estimated that by 2011, the global LED lighting market will grow to 1.4 billion US dollars, of which architectural lighting and commercial lighting will be the first to become the main force. Currently, the quality of LED lighting products on the market is uneven, and the product itself is in heat dissipation and color. There are still problems to be overcome at the level of standard setting and business model.
According to research statistics from the Industrial Technology Research Institute, the global lighting market will grow to US$132 billion by 2011. North America is still the region with the most electricity consumption in the world, but the growth of lighting demand in Europe and the United States will slow down, including China and Asia. Demand from emerging countries such as Africa will grow rapidly, driven by new construction needs, power penetration, and increased use of outdoor lighting. Among them, the market size of lighting lamps is 25.4 billion US dollars, and the market size of lighting equipment/devices is 106.6 billion US dollars. Commercial lighting accounts for 43% of the total lighting market in the world, with the highest proportion. The total electricity consumption in the retail, office, warehouse, education, health care and other applications accounts for 70% of the total commercial lighting market.
At present, the proportion of LED lighting in the global lighting market is still low. In 2007, the global LED lighting market was about US$330 million. If compared with 2006, the annual growth rate will reach 60% and it will grow rapidly. In addition, the market demand pattern is a small variety, so it is still the basic city of the Institute of Engineering Research Institute believes that with the gradual decline in the average cost of LEDs, coupled with the continuous improvement of product quality, the speed of commercialization of LED lighting will also accelerate.
Among them, the largest application area of ​​LED lighting at this stage is architectural landscape lighting, accounting for 45% of the global LED lighting market. Due to the increase in luminous flux and luminous efficiency of white LEDs, the adoption ratios such as garden lights, searchlights, ladder lights, and balcony lights are growing rapidly, especially in China, which accounts for 36%. ITRI ​​estimates that the LED architectural landscape lighting application market will grow to 470 million US dollars by 2011, with a compound annual growth rate of 38%, accounting for 50% of the overall LED lighting market.
Retail display lighting is also a growing area of ​​LED applications. ITRI ​​said that although the retail display lighting application accounted for only 3% of the global LED lighting market in 2006, and the market size was only 6.5 million US dollars, with the increasing importance of the integrated product features of the display space lighting application, it is expected that the retail display lighting application will be In the next few years, it will grow rapidly. By 2011, the global LED retail display lighting application market is expected to grow to 144 million US dollars, accounting for 10% of the global LED lighting market. The compound growth rate will reach 68% from 2006 to 2011.
Consumer hand-held lighting currently accounts for 15% of the global LED lighting market. The main application products include flashlights, reading lamps, miners' lamps, etc. Among them, LEDs have a penetration rate of 30% in professional and special-purpose flashlights. The main reason is that in the field of special professional flashlights, the market price sensitivity is more general. Consumption is low. It is expected that the key to the overall penetration of LED flashlights in the future will still be the reliability and price of the product itself. ITRI ​​estimates that the market for LED consumer handheld lighting products will grow to $99 million by 2011, with a compound annual growth rate of 27% from 2006 to 2011.
As for the current font/contour lighting applications with a global LED lighting market share of 17%, growth is expected to be lower than LED lighting applications such as architectural landscapes, retail displays, and consumer handheld products. ITRI ​​pointed out that the main reason is that the current font/contour lighting applications are mostly small-scale projects. The main customers are mainly global large-scale chain enterprises such as McDonald's and Wai-Mart. The scale of the manufacturers is small and territorial. For example, in the United States, there are more than 6,000 manufacturers of font/contour lighting. Therefore, it is estimated that by 2011, the font/contour lighting application market will only grow to $79 million, with a compound annual growth rate of 18%.
ITRI ​​pointed out that LED lighting products not only have the advantages of small size, but LED lighting products have also fully grasped the advantages of semiconductor lighting to emit light, reducing the loss of light source, and the long service life of semiconductor lighting can reduce maintenance. Costs and other costs, in addition to regulating the brightness is also more able to withstand frequent switching actions. It is expected that under the trend of global energy demand growth and high price, the growth of traditional light source technology will face bottlenecks. With the continuous improvement of LED technology and cost reduction, the long-term obstacles in the LED lighting market are not big.
LED lighting applications should be accelerated, and problems from the technical, standard, and business models must be overcome in the short term. Technical issues, including heat dissipation, color, system reliability and efficiency improvements, are still subject to continuous improvement. And the formulation of product standards, measurement standards, control and interface standards must be further integrated. In addition, the current LED lighting products on the market are mixed, many product information is not complete enough, it is easy to mislead consumers, and there are competitions from other high-efficiency light sources including OLEDs and traditional low-cost light sources. The LED industry may also carry out. Industrial restructuring and adjustment.
