module is the best choice for downstream businesses
LED lighting industry in China is about to enter the modular era. Modular is the light source, cooling components, driver power synthesis module,[link widoczny dla zalogowanych], production, through a die to create a standardized LED lighting products. Despite the extension, the chip can not bypass the patent barriers to foreign companies, but the module if the mass production, then have a price advantage, and one-time, personalized production, the cost is much higher. Therefore, the downstream businesses, LED lighting applications, modular is the best choice.
module has significant characteristics: First, good process, good modular street repair, street lights most of the country now using a low-power chips, broken a few very easy to repair, but the basic modular on the use of the high-power chips, not easily broken, even if the bad is also easy to repair. Second, lower development costs, with less investment to produce high-quality LED lighting products. The efficiency of LED lights 5 times higher than the energy-saving lamps, if the module is able to achieve large-scale production, the cost can be reduced by 2 to 3 times. Although the ratio of energy-saving lamps LED lamps expensive, but the conservation of energy is much higher than the energy-saving lamps, LED lamps many companies would choose, because a little more money can solve the energy problem, but in the long run, more money.
As LED technology advances, technology is developing too fast, LED standards established very difficult, but in the LED lighting industry, if there is no standard mobile phone charger will be the same as now, a variety of LED energy saving lamp vendors can not compatible. But now, the relevant state ministries and commissions under discussion. In the upper reaches of the extension, chips, domestic enterprises have difficulty than foreign companies,[link widoczny dla zalogowanych], but the advantage is obvious in the downstream, especially in the packaging field, and now 80% of the world, LED lighting package in China. Modular is actually a standardized, industrialized approach to the package, and through technical innovation, process innovation to reduce costs, achieve economies of scale manufacturing purposes.

countries in the Ministry of Science and lighting engineering, lighting is a strategic industry, Science and Technology to promote energy efficient lighting for certain subsidies. Strength of the LED, China ranked as the top five in the world, with South Korea and China Taiwan for the second echelon. In epitaxial, chip and other upstream areas, Japan, United States, Germany and formed a leading patent alliance, and in the light effect on the domestic chip with foreign chip difference of 20%, but we have a huge cost advantage. In general, the epitaxial material, chips, auxiliary materials and equipment investment payback period is 10 years, the mainland's Xiamen upstream companies such as An, Di source Wuhan, Dalian Road, a long-term plan with the United States and so on. But for most companies, they can only packages, application development. Dialectically, the state's guiding ideology is the application of Science and Technology for Development, to packaging applications featuring a short, flat, fast to win.
LED lamps diversification, radiators, drive power is more expensive than chips. Many sources of chips, both from Japan, the United States, Germany imports, but also from Korea, China Taiwan to buy, the chip does not affect the cost advantage of Chinese Mainland. From the current point of view, if the standardized Mainland LED industry will have an advantage over the United States. LED is a very flexible product, standardization is very important, the most important is the standardization of end products, that is modular. Part of the package, due to the high cost of customized manufacturing, if the industrial production, well standardized, the costs can be reduced by 1 / 3. Modular in the premise of ensuring the quality of products significantly reduce the cost of end products manufactured through a modular usually have a clear price advantage.
some traditional lighting companies have realized that, like NVC, Op and other traditional lighting giant also increased R & D investment, but they have to fully enter the LED lighting field, the use of modularity is a shortcut. In general, the standardization of production to achieve low-cost, traditional lighting companies need at least 5 to 10 years.
present, the standardization of Chinese companies have not done enough, and Technical Supervision Department and other countries has played the role of industry standards, together with the implementation of the modular industry organizations made great efforts.
the arrival of technological innovation, will make the industry reshuffle, integration. China's semiconductor lighting gap with foreign countries is 10 years, technology alone is not enough, but also through the integration of capital, can only become bigger and stronger. Modular to market first, rely on one or two companies is not enough, the most important thing is the whole industry stronger,[link widoczny dla zalogowanych], bigger.

modular electric light is a breakthrough new products
in China, more than 2,600 enterprises to enter the LED field, 30 to 40 engage in chip technology, 600 out package 2000 engaged in the downstream industry. The LED light source, the domestic enterprises do not have the initiative,[link widoczny dla zalogowanych], with the foreign share of 10 to 20 years gap. In the core technology, the Chinese abroad in the short term is impossible to overtake, only the concept of innovation, the introduction of advanced technology to simulate the close, we can be a comparative advantage. As China's automotive industry, as previously a joint venture with foreign enterprises, OEM to get the technical ability to embark on a road.
a business can take off depends on two factors, one technical, one marketing From EMKT.com.cn
