LED industry environment optimization core technology breakthrough

To say that the market is the first hot industry in 2010, LED deserved. Data show that in 2010, China's LED industry output value will be more than 150 billion yuan. Green lighting as the core of the emerging LED lighting industry is now accelerating the development of the country. On the one hand, the government is stepping up the implementation of strong policies to boost the implementation of this industry, on the other hand, companies are also accelerating the layout in this area. With the promotion of LED lighting efficiency and government subsidies or incentives, LED will be more widely used. Experts said that on the basis of the efficiency and cost of breakthrough, pay close attention to the permeability, vigorously promote energy-efficient lighting project at the right time. Newspaper invited experts on how to promote healthy and healthy development of China's LED lighting industry recommendations.

Chips are relatively weak but optimistic

Domestic chip has a strong cost advantage. The key is to change the operation of the development concept.

Although the upstream enterprises of LED in China are at a disadvantage in the core technology, industrial chain, scale, but the development prospects should be optimistic. In recent years, our upstream chip technology and the international first-class level of distance has not been opened, with the domestic watt class chip packaging high-power LED light efficiency of more than 80lm/w, has been able to meet many application requirements. We also have independent intellectual property rights of silicon substrate GaN chip technology, under the same conditions, the light effect has exceeded 60lm/w. At the same time, the domestic chip in the field of suitable application has a strong cost advantage.

Due to the current domestic upstream enterprises either in concept, or with foreign in operation management and technology development organization, there is a big gap, which determines our technology, operation and quality of products and they will be very different, most of our products are low. For example, the current size of the LCD backlight is required for almost all of the LED chip companies and domestic independent. The Ten City million light required high efficiency and high power LED chip, the domestic upstream companies can rarely provide. The key is to change the concept of "advantage of backwardness".

China's chip extension industry in recent years has made considerable progress, especially small and medium size chip (15mil) technology has made rapid progress, can satisfy the display, backlight, traffic lights for the vast majority of demand, small and medium size chip is also able to meet the 30% lighting demand. The size of the tile class chip currently domestic enterprises can not mass production, 90% by imports.

To realize the localization of MOCVD equipment

Focus on key development. Drive the development and progress of related industries.

Related to the production of the key equipment MOCVD, currently the world can produce MOCVD epitaxial furnace equipment only the United States, Germany, Japan and South korea. China also has several units developed MOCVD equipment, but also out of the prototype for the use of units to try, but did not progress. Because the MOCVD equipment is the key equipment in the development of LED industry, which plays an important role in the development of LED industry, the relevant departments of the State shall focus on the original trial of MOCVD equipment units of talent and resources, investment for development, to solve the key technology in manufacturing equipment, master the core technology with independent property right, and as soon as possible to achieve localization MOCVD production equipment. Only in this way will accelerate the development of LED industry, as well as reduce the cost of LED related products, to achieve greater industrial development.

MOCVD and other key equipment is a manifestation of the will of the state, the state must vigorously invest and fully support. In addition to the whole system, but also pay attention to the key parts of the manufacturing and supporting capacity, such as high quality, high purity graphite crystal material parts, stainless steel materials and parts, materials, surface treatment, and pressure, flow, temperature detection, vacuum pump etc. are essential to MOCVD. Therefore, the successful operation of the MOCVD project will promote the development and progress of a large number of supporting industries. Of course, the success of MOCVD and other key equipment localization means that LED cost reduction, localization of key equipment will greatly reduce the manufacturing cost of LED.

The standard gradual establishment of the LED standard

Set up an inter departmental leadership team to develop appropriate specifications or standards. A baodatianxia, reversing the situation, strengthening the division of labor.

Pengwanhua

After several years of efforts, the relevant departments to develop the semiconductor lighting industry standards have been approved and approved by more than 50 items. The application of LED products because of many varieties, is under the jurisdiction of different departments, more important is because the LED technology has developed rapidly, the performance of LED application products constantly changing requirements and improve, the product is not yet mature, so it is difficult to develop LED application of appropriate product standards. The available two solutions, one is on the application of LED products, the first can make recommendation technology norms and recommended in the industry, to be mature products for revision of industry standards or national standards; two is the condition of the local government, due to the development of LED region with the demand of the products, can be the first the formulation of local standards, used in the local area, the better the local standards can also be recommended in the industry, the product is mature after revision as the industry standard or national standards.

LED lighting standards involving a wide range, from the lamp to the device, which also has modules and components; also involves more departments in the development of standards in the process of various departments to reach a consensus, including lighting electrical industry and
