It is undoubted that the world LED industry will have explosive growth. In the face of huge market opportunities, the world's major LED companies are increasing research and development, new technologies continue to make breakthrough progress, LED lighting technology innovation is constantly accelerate. Japan Nichia Chemical launched a 100 lm/W white LED product in June 2006. In December 2006, it also developed a 150 lm/W white LED for laboratory lighting. In early 2007, Lumileds successfully developed luminous efficiency. 115lm/W, high-power white LED with a luminous flux of 136lm. In July 2006, Cree developed a white LED with a luminous efficiency of 131lm/W. In February 2010, it announced that its laboratory data has reached 208lm/W. This is a Landmark records.
At present, LED lighting industry has formed a three-footed industry distribution and competition pattern dominated by the United States, Asia, and Europe. International Nichia Chemical, Toyota Synthetic, Cree, Philips, OSRAM and other five giants monopolize the high-end product market, they use their innovative advantages in new products and new technologies, mainly engaged in the production of high value-added products.
These five major companies have their own characteristics in terms of products and markets. Nichia Chemical and Toyota Synthetics have played an important role in the development of LED and formed a complete LED industry chain. Nichia Chemical produced the first blue chips in 1994, and In the sapphire substrate technology patented technology has a monopoly advantage. The United States Cree Corporation has formed a complete LED industry chain on the silicon carbide substrate technology route and has a monopoly advantage in patent technology. Lumileds (Philips Lumens) is focused on high-power LED research and development and has a strong presence in white light lighting. Osram, Germany, has advantages in thin film chips and phosphors.
In addition, it is worth mentioning that the LED industry in Taiwan in China has risen rapidly in recent years, and its chip production and packaging output occupy the top position in the world. According to statistics, the market share of Taiwanese products in China is more than 60% in the world, but its product quality cannot yet enter the first echelon.
Governments of various countries actively formulate environmental protection laws and prohibit the use of incandescent lamps. Traditional lighting giants have introduced LED new light sources to accelerate the formation of new business models.
As the global lighting power consumption is 20% of the total annual electricity consumption, and as many as 90% of the electrical energy is converted into heat energy, it is not economical. Under the consideration of environmental protection and energy saving, LED lighting has rapidly become a concern. Technology and industry. At the same time, governments of various countries actively formulate environmental protection laws and regulations. Under the stimulation of dual interests of the market and regulations, the global LED industry is rapidly growing.
The advantages of LED lighting are self-evident. LED lamp has high luminous efficiency and long life. Its luminous efficiency can reach 2.5 times that of fluorescent lamps and 13 times that of incandescent lamps. The luminous efficiency of incandescent lamps is very low, only 5% of the electrical energy is converted into light energy, and 95% of the electrical energy is wasted. Fluorescent lamps are better than incandescent lamps, with 20% to 25% of electrical energy converted to light energy, but 75% to 80% of electrical energy is wasted. Therefore, from the perspective of energy efficiency, the utilization efficiency of these two light sources is very low. Therefore, the benefits of LED lighting are obvious. In 2007, Australia introduced the first ban on the use of incandescent lamps in the world. In March 2009, the European Union passed regulations on the elimination of incandescent lamps. Therefore, two major traditional lighting companies in the world, OSRAM and Philips, have accelerated their deployment in the field of LED lighting in recent years. Their entry promoted the rapid development of the LED lighting market and accelerated the progress of LED technology.
With the rapid development of the LED industry in the lighting field, traditional lighting giants hope to make the lighting products more innovative by introducing new light source designs. Therefore, the two areas of LED lighting and traditional lighting are gradually being combined to accelerate the formation of a new lighting business model, which is very conducive to the rapid promotion of the use of LED lighting.
