LED lighting is difficult to popularize technology development has become a bottleneck

Low carbon energy conservation advocacy, LED lighting surging, ten city million to allow China to become the world's LED street test site. In the Ministry of energy conservation and environmental protection to create a low-carbon economy, China is bigger semiconductor lighting industry cake. According to the relevant agencies, in 2010, China's LED industry output value will be more than 150 billion yuan, compared with the total output value doubled in 2008, the total output value of about $70 billion in 2008. The big market cake so temptation, promote the birth of Chinese nearly 3000 enterprises including 70% coexistence, focus on the industry downstream, domestic LED epitaxial material, chip with low power LED chip, and more than 80% devices rely on imports.

China is the world's largest producer of lighting and lighting, but the main production of low-end products, accounting for about 18% of the global market share. In the industry chain, LED epitaxial wafer with LED chips accounted for about 80% of the industry's profits, LED applications accounted for about 10%-20%; LED package is less than 10%.

The key in the development of LED industry is light effect

The LED packaging costs accounted for 50%, in order to reduce the overall cost of LED, we must choose the packaging structure more suitable, so changing the package structure of the existing package, to achieve a reasonable cost, will be LED lighting market acceptance of the most effective and most direct way. Of course, LED chip technology, with the increase in shipments, with more large size wafer fabrication process, are also constantly reduce costs, at a rate of 20% annually in recent years in the lower, if the package cost from the current account for the total cost of 50% reduced to 20% to 30%, the application of LED lighting to a meeting the new order of the size of the market.

In the lighting market, the rapid expansion of LED lighting penetration, market price war brewing in 2010. However, the concern is that control the core technology of LED foreign companies if eager to pull LED low cost, simple LED downstream of the Chinese LED industry only to achieve low-cost and allow the market to heat up to sacrifice their own profits, but not the downstream products of technical support, if the price is cheaper, and how many people dare to use. However, only the master and the cost difference between the products LED manufacturers have a chance to win, the traditional brand lighting manufacturers lay a pathway and diversified product line advantage, LED lighting industry is new or smaller are difficult to surpass, once the lighting manufacturers large and strong style price war, these small the factory will be difficult to survive, and fear of falling were eliminated or mergers and acquisitions market.

LED light source is the starting point and the driving force for the development of the cause of LED, a direct impact on energy efficiency, but also affect the government's determination, but also affect the recovery cycle and operating profit of investors. Chen Daqing, director of Tianjin city landscape and Landscape Management Committee believes that promoting the improvement of light efficiency is the key to technological development. He stressed: as any person in the LED industry, we must be soberly aware that the key to the development of LED industry is light efficiency".

In addition, the development of LED lighting technology, in addition to its resistance to heat and specifications, price and other factors, CFL energy saving lamp, fluorescent lamp technology is also in development, the luminous efficiency of office lighting system T5 lamp has reached 100lm/W level, CFL energy-saving lamps also have 3W specifications of ultra small products come from the current LED and energy-saving lamp price is concerned, the popularity of LED lighting still has a long way to go.
