As a new type of light source, LED has seen technological progress in recent years. However, in the development of LED lighting products in the country, there is a lack of scientific attitude, simply imitating traditional products, and the homogenization of products is serious, resulting in many unnecessary losses and negative effects. It is also an indisputable fact.

Saving energy, protecting the environment, and developing green lighting products are the key tasks that China's lighting industry has been actively developing since the early 1990s. Therefore, when high-efficiency LEDs emerged, they immediately attracted attention from relevant domestic ministries and commissions. In June 2003, the Ministry of Science and Technology led the establishment of the “National Semiconductor Lighting Project Coordination Leading Group”, which opened the curtain for the domestic LED lighting industry. In early 2009, the Ministry of Science and Technology launched a pilot project of the “Ten City Ten Thousand Miles” semiconductor lighting application project, setting off a domestic climax of LED street lighting. In October 2009, in response to the development of domestic LED lighting, the six ministries and commissions of the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development issued the "Opinions on the Development of LED Lighting Energy-saving Industry", which clarified China's LED lighting industry's development goals by 2015. The specific target is to increase the annual average output value of semiconductor lighting energy-saving industry by 30% by 2015, of which functional lighting accounts for 20%, liquid crystal backlight sources reach 50%, and landscape lighting products have a market share of over 70%.

LED has brought a revolution to the lighting industry. In the future, LED has become the mainstream in the field of lighting. It is a consensus in the industry and beyond. As long as LED manufacturing enterprises strengthen investment, establish a sound detection system, strengthen research, be creative, understand the characteristics of LED light, fully understand the standard, understand the use of ambient lighting requirements, understand user needs, will be able to use the LED lighting industry to expand the company's business To be stronger, to contribute to the future of China's lighting industry in the international lighting field to become a strong country.

LED lighting industry development LED applications are divided into two major categories of display and lighting. The new type of lighting with light emitting diodes (LEDs) as its light source is called semiconductor lighting, or LED lighting for short, and the industry dominated by semiconductor lighting is called the LED lighting industry. LED lighting industry chain includes upstream raw materials, equipment (single chip) and epitaxial growth; midstream chip manufacturing; downstream packaging and product development, production and application; supporting industries including related equipment, accessories, materials and so on.

The upstream links have high technical content, large capital investment, large quality impact, and high profit margin. The LED luminous color and luminous efficiency are related to the production of LED materials and processes, and the upstream accounted for about 70% of the LED manufacturing cost, which is extremely important for the LED industry; It is a technology and capital intensive link. The chip is currently the most intense link in patent competition, with the characteristics of large investment intensity but slow performance; the downstream link includes the development and production applications of LED packaging and lighting, and is the most closely linked with the market, technology With a relatively low content and a low investment threshold, it is the largest and fastest growing field in the LED industry.

At present, the global LED industry is distributed in a pyramid state. The United States, Europe, and Japan occupy the top of the pyramid, and its output value accounts for about 60% to 65% of the world's total. Its technology, patents, and output value are ahead of other countries and regions. The Taiwan region and South Korea are located in the middle of the pyramid. The ratio of output value accounts for about 30% to 35% of the world's total. The technology is slightly inferior and the production capacity is larger, but the added value of the products is slightly lower. At the low end is China, Malaysia and other places, which account for about 3% to 6% of the world's total. The technology is relatively low-end, lacks core patents, and is relatively small. Its production capacity and output value are relatively low, but its rate of increase is rapid.

In 2009, the semiconductor lighting industry in China generally fluctuated. In the first quarter, due to the impact of the international financial crisis in 2008, the industrial development was slow, and the shrinking of exports became a prominent problem. A considerable part of the enterprises had difficulties in business or even closed down. From the second quarter onwards, with the advancement of application demonstration projects in China's “Ten Cities and Ten Thousand Ones” and improvement of domestic and international market conditions, the LED industry has started to recover steadily. In the second half of the year, the international and domestic real economy has seen a low point, showing a recovery momentum. At the same time, the situation of China's LED industry continues to improve, especially under the country's policy of vigorously advocating low-carbon economic model, LED lighting has become a hot industry.

Opportunities and challenges faced by LED lighting From 2007 to 2009, despite the chaos of the industry, local LED companies called for the introduction of standards, but there is no major practical change. From the 2013 National Standardization Committee's lighting standard system revision plan, we can see that the country has formulated and supplemented LED lighting standards, and has introduced intensive plans. This is only possible when the industry is relatively mature. The standard. From 2011 to 2013, we have never had any doubts about the LED lighting industry. With the support of national policies and the more mature industries, standards have gradually improved, and more and more manufacturers' product quality has been improved and guaranteed. The technology will become more and more mature, and the price can be reduced to the level acceptable to users.

First, the introduction of product standards is slow, the system is not uniform, and manufacturers are at a loss. The introduction of a plan or standard often takes two years or so, but LED lighting, as a new technology, will undergo major changes and improvements almost every year. When standards are set, they are less suitable for current technology. situation. Therefore, the standard of LED is difficult to formulate quickly. At the same time, different industry associations and different local governments in China, such as Guangdong, Fujian, the LED Industry Alliance, and the Ministry of Industry and Information Technology, are leading the formulation of their own standards. Ultimately, the manufacturers and owners are at a loss, and the confusion of standards has also led to confusion in the industry. Manufacturers fish in troubled waters.

The second is the lack of product quality stability. In order to occupy the market, a considerable number of companies sacrificed product quality and adopted low-cost malicious competition, resulting in poor stability of LED lighting products sold in the market, and owners evaluating more negative information.

Third, the product's cost performance. The overall price of LED is also higher than that of traditional lighting fixtures. For example, the development of street lamps is relatively mature, but the street lamps are put into use for the first time at a higher price, and therefore the EMC mode is adopted. However, for the general lighting market, an incandescent lamp has a minimum of 5 hairs, energy-saving lamps range from a few blocks to more than 20 blocks, and LEDs have to sell at least 40 to 50 renminbi. For the obvious price difference, ordinary people cannot accept it.

In terms of product cost performance, next year's product prices will have the opportunity to approach the price of energy-saving lamps. They have calculated the cost and they should have the opportunity to do so next year. "Now we are talking about LED products, which claim to have 30,000-50,000 hours externally. The price is often more expensive, which is about 3 to 5 times that of energy-saving lamps. If you use home lighting for 5 hours a day, you can use it for at least 12 years. I would like to ask if an ordinary family would use a light bulb. Will it really take 12 years? "So, do we need to consider separating the commercial lighting from the civilian lighting product line? For public places such as shopping malls, subways, road lighting, etc. For a long time, the LED guarantees a life of 3 to 50,000 hours. For civil lighting, it does not have to be 30,000 hours. We only need to design the lifespan to 15,000 hours, and we can lower the price. At the same time, it is a family and general The use of the place can also guarantee the service life of 3 to 5 years or more. In fact, the products of the international giants are now changing in this direction."

For example, through technical innovation, whether new materials can be taken into consideration in the raw materials used in the original lamps, aluminum materials may be replaced with heat-conducting plastics; PC lamp shades may be replaced with glass; The amount will be less. Or like AC LED lighting products, remove or simplify the power supply, so that the price of the product can be lowered.

Conclusion:

With the increasing international competitiveness of China's LED lighting products, in the future, it should be more inclined to enhance the product's international competitiveness by improving the core competitiveness of the industry. While breaking through the core technologies of the industry, we must also recognize the unbalanced status of China's economic development regions and the resource endowments of unlimited supply of labor, vigorously develop labor-intensive LED lighting manufacturing enterprises, and continue to maintain China's international competitiveness in such products. Advantage.
