Module is the best choice for downstream enterprises

China's LED lighting industry is about to enter the era of modularity. Modular is the light source, cooling parts, drive power synthesis module, mass production, through the mold to create a standardized LED lighting products. Although the extension, the chip can not bypass the patent barriers of foreign companies, but if the bulk production module, the price advantage, and one-time, personalized production, the cost is much higher. Therefore, the downstream LED lighting applications for enterprises, modularity is the best choice.

The module has significant characteristics: it is a good technology, modular lamp good repair, now domestic lamp is mostly used in small power chip, broken a few maintenance is not convenient, modular basically is used in high-power chip, not easily broken, even if the bad is convenient repair. Two is to reduce the cost of development, with less input can produce high-quality LED lighting products. LED street lamp is 5 times higher than the efficiency of energy-saving lamps, if the module can achieve large-scale production, the cost can be reduced by 2~3 times. Although the LED lamp energy saving lamp than expensive, but its energy saving ratio of energy-saving lamps is much higher, many companies will choose LED lamps, because a little more money can solve the energy problem, but in the long run, more money.

Because LED technology change rapidly, technology is developing rapidly, it is difficult to LED standard established, but in the LED lighting industry, if there is no standard mobile phone charger will be like now, between the various LED energy-saving lamp manufacturers are not compatible. But at present, the relevant state ministries are still under discussion. In the upstream epitaxial, chip field, domestic enterprises more difficult than foreign companies, but the advantage in the downstream is obvious, especially in the field of packaging, and now 80% of the world's LED lamps packaged in china. Modularization is actually the use of standardized, industrialized approach to packaging, and through technological innovation, technological innovation to reduce costs, to achieve the purpose of large-scale manufacturing.

Modularity is the standardization of terminal products

In the Ministry of science and technology of national lighting engineering, lighting is a strategic industry, the Ministry of science and technology to promote efficient lighting has a certain subsidy. In the LED strength, China ranked five in the world, with South Korea and China Taiwan for the second echelon. In the upper reaches of the extension, chips and other fields, the United States, Japan, Germany is in the leading position and formed a patent alliance, while the domestic chip in optical effect and foreign chip difference of about 20%, but we have a huge cost advantage. In general, epitaxial material, chip, material and equipment investment payback period is 10 years, the mainland upstream enterprises such as Xiamen Saman, Wuhan Di source, Dalian road beauty have a long-term plan. But for most companies, they can only be used in packaging, application development. Dialectically, the guiding ideology of the Ministry of science and technology is to promote the development of applications to packaging applications for the characteristics of a short, flat, fast win.

LED lamp diversification, radiator, power supply costs higher than the chip. Many sources of chips can be imported from Japan, the United States, Germany, South Korea, China can also be purchased from Taiwan, the chip is not enough to affect the cost advantage of manufacturing in mainland china. From the current point of view, if the realization of standardization, the mainland LED industry will have an advantage over the United states. LED is a very flexible product, standardization is very important, of which the most important thing is the standardization of terminal products, that is, modular. In the packaging process, due to the high cost of personalized manufacturing, if industrialized production, do a good job of standardization, the entire cost can be reduced by 1/3. Modularization can greatly reduce the cost under the premise of ensuring the quality of the products, and the terminal products which are manufactured by the modularization have obvious price advantage.

Some of the traditional lighting companies are aware of this, like NVC, OPPLE and other traditional lighting giant also increased investment in research and development, but they have entered the field of LED lighting, the use of modular is a shortcut. In general, to achieve low-cost standardized production, the traditional lighting companies need at least 5~10 years.

At present, the standardization of Chinese enterprises is not enough, the State Bureau of technical supervision and other national departments have played the role of industry standards, and industry organizations for the implementation of modular made great efforts. The advent of technological innovation, will make the industry reshuffle, integration. China's semiconductor lighting gap with foreign countries is 10 years, relying on technology is not enough, but also through the integration of capital, only to do bigger and stronger. Modular to the market first, relying solely on one or two companies is not enough, the most important thing is to make the whole industry stronger, bigger.

Modularity is the breakthrough of new products

In China, more than 2 thousand and 600 companies to enter the field of LED, 30~40 engage in chip technology, the 600 engage in packaging, the 2000 engage in downstream industries. In LED light source
