Most market participants believe that LED lighting will replace ordinary lighting and is expected to be the biggest winner in green lighting products.
This is because the LED semiconductor lighting industry itself is a model of low energy consumption and low emissions. Its energy consumption is only 1/10 of that of incandescent lamps, 1/3 of energy-saving lamps, and the theoretical luminous efficiency and lifetime far exceed that of incandescent lamps. Fluorescent light. Therefore, it is inevitable to obtain a wide range of market pursuits.
Because of the energy-saving advantages and market opportunities, many domestic and foreign companies such as GE and Inspur Group have also increased their actions in the LED lighting market.
At the same time that the market is optimistic, over-investment has already begun to appear in this industry, and a situation of small factories has formed. Enterprises are rushing to invest large sums of money in research and development, trying to seize the commanding heights of each node of the industrial chain with technology.
These problems are extremely risky for Zhang Guangming, a lighting industry marketing expert. He believes that the current status of China's LED lighting industry is very similar to the mobile phone market four or five years ago: the entry barrier for LED lighting industry is too high, only companies with considerable capital and technology can enter this field; LED lighting terminal products The price is too expensive, resulting in the market can not explode; the industry chain is too long, resulting in a long product development cycle; technology-leading companies are involved in every link of the industry chain; due to unclear division of labor, large-scale manufacturing has not yet formed.
Moreover, due to the fact that the specifications of traditional lamps have been standardized and the manufacturing cost can be reduced, the degree of customization of LED lighting is high, resulting in low capacity utilization. Because the price of the product is more expensive than the traditional sodium lamp, the one-time investment is large, which makes the local government dare not invest boldly, resulting in the speed of promotion and application of LED lighting products in China, far behind other countries. At the same time, China's LED lighting industry's entire industry resources are scattered, there is no scale, resulting in enterprises can only import high-priced chips from abroad, low bargaining power, so that the cost remains high. "The current lack of core patents in the industry, especially the most critical white light, high-power LED lamp thermal balance problem, long-lasting and efficient phosphor and other patents, has been monopolized by Europe, the United States, Japan, suppressing the development of China's industry."
In addition, because it is an emerging market, in addition to chip manufacturers, the LED lighting market is dominated by two types of enterprises, one is from the chip packaging link to the final product, all the links are in their own hands, so the company's investment is thousands Another type of enterprise is to purchase and package the light source to develop application products, and then solve the problem of circuit heat dissipation and driving power. These enterprises often face technical problems. Once the technology is backward, they will lose market share or even lose money. Form a vicious circle.
If these problems are not solved well, it will always hinder the development of LED lighting products.
To this end, Zhang Huming suggested encouraging local governments to vigorously promote the application of LED lights and policy support, and take the lead in municipal engineering and public institutions, such as government buildings, hospitals, schools, urban trunk roads, tunnels, etc., not only for enterprises. Bring direct orders and indirectly play a good public demonstration role.
At the same time, update testing methods and equipment to develop uniform testing standards in the industry. At present, there are many manufacturers in China that can do LED lights, and the technical level is uneven, which leads to chaotic competition in the industry, which greatly affects the quality and credibility of LED lights and weakens users' confidence. Empirical evidence shows that the source of these problems is mainly from the chip and its packaging process. Therefore, it is recommended that high-power LED lighting applications should refer to the international NIST standard, that is, the optical power of the chip should not be less than 300 light milliwatts, and must be certified and authorized by the chip manufacturer when purchasing.
