As governments around the world reach a consensus on green energy conservation and environmental protection, the future of the industry related to green environmental protection and energy conservation is bright. In 2009, the LED lighting industry showed no signs of a significant weakening of the global economic crisis. Under the strong promotion of the Chinese government, China's LED lighting industry is rapidly heating up. In 2009, it became the first year of LED lighting. The Chinese LED lighting industry chain is fast in this economic crisis. With the growth and improvement, the new generation of lighting technology for LED navigation and energy saving and carbon reduction has developed rapidly, and millions of companies that drive the LED lighting industry chain are thriving.
LED light source is energy efficient and has no carbon emissions
The LED light source is a new generation of light source for solid-state illumination. As a fourth-generation lighting fixture that is green, energy-saving, energy-saving, and long-lived, the LED light source has sprung up, attracts attention, and is rapidly developing. As the fourth generation of new energy-saving light source, LED light source was used as the light source of various lamps. The incandescent lamp as a light source has a luminous efficiency of only 5%, and the luminous efficiency of the LED light source is almost 90%. LED lighting has become the focus of everyone's attention because of its high energy saving, long life and environmental protection. In recent years, high-brightness LED light sources have experienced rapid advances in their manufacturing technology, and their production costs have been declining. Now almost all lamps can use LED light sources as high-brightness, high-efficiency, energy-saving, carbon-free lighting sources. .
LED light source requires driver IC
The current DCLED light source is a semiconductor device that operates at a low voltage (VF=2→3.6V) and a large current (IF=200→1500mA), and must provide a suitable DC constant current to emit light normally. The technology of direct current (DC) driving DCLED light source has become more and more mature. Since the power supply used in our daily lighting is high voltage alternating current (AC100-220V), it is necessary to use the buck technology to obtain a lower voltage. The power supply is stepped down, and then the alternating current (AC) is converted into direct current (DC), and then converted into a direct current constant current source by the driving IC to cause the LED light source to emit light. Therefore, the system application scheme of the DC driving LED light source must be: switching power supply + constant current source. LED lamps must have a certain amount of space to house this power module, but for E27 standard screw luminaires, the space is very limited and difficult to place. Whether it is via transformer + rectification or switching power supply step-down, the system will have a certain amount of loss. When DCLED lamps are switched between AC and DC, about 15 to 30% of the power is lost, and the system efficiency is difficult to achieve more than 90%. If the LED light source can be directly driven by alternating current (AC), the system application scheme will be greatly simplified, and the system efficiency will easily reach 90% or more.
The government promotes the rapid development of the LED lighting industry Throughout the global market, examples of government funding to promote industrial development abound, such as the popularity of solar power generation in Germany to every family is a good example of success. Today, the 21-city LED light plan of the Chinese government is a good way to pull down domestic demand and expand the world's largest market in the subprime mortgage crisis! In 2009, the Chinese government mobilized domestic demand and launched the “Ten Cities and Ten Thousands†LED lighting popularization and energy-saving campaign. Today, it has been clear that the national 21-city LED lighting should exceed 10,000 lamps. National street lamps and 24-hour continuous use of tunnel lights will become the first replacement. The key projects, the subways in Beijing, Shanghai, Guangzhou and Shenzhen have started to popularize the LED fluorescent lamp energy-saving project. Therefore, the entire LED lighting market is expanding and spreading to the world. Bringing the technology and production capacity of the LED lighting industry to the high-tech development, it has created a group of emerging enterprises in the LED lighting industry chain and created new employment opportunities. Drive the rapid development of China's LED lighting industry, so that the upper, middle and lower reaches of China's LED industry will grow rapidly in expanding domestic demand, so that all relevant technologies in the LED lighting industry chain can be improved in quality and new development. People all over the country can have a personal understanding of LED lighting, which is conducive to the massive demand for LED lighting in thousands of households in a few years, which is beneficial to China to become the world's largest LED lighting production base. At the same time, China is also the largest LED lighting. market. This impact will last for five years and ten years until the next generation of lighting technology is born. At present, South China, East China, and North China have shown a booming LED lighting industry. Let us see the information of spring. The green LED lighting is rising like the sun at six or seven o'clock in the morning.
Advocating the use of domestic products is the foundation for the development of national industries. In the “Ten Cities and Ten Thousand Cities†plan, there is a requirement that LED components must reach 60%. This is a good measure. We should work hard and have the responsibility to improve the LED lighting system. The localization rate, we should inspire our national enterprises and our engineers, and strive to modernize LED light source, LED driver IC, lamp design, optical design, and heat dissipation system. . . All are world-class. The LED industry technology in Taiwan has always been at the forefront of the world. Therefore, our localization should be the concept of Greater China and should include products and technologies in Taiwan, Hong Kong and Macau. Domestic enterprises should actively introduce advanced LED technology from Europe, America and Japan. At the same time, they should promote the use of domestic products, especially the technologically advanced LED-related products in Taiwan and Hong Kong. Whenever possible, use Spare Parts of our resources and increase the localization rate in products as much as possible. To contribute to the global sales of LED lighting manufacturers made in China.
Direct docking between upstream and downstream is a new mode of cooperation for modern electronics industry
IC manufacturers provide end-users with solutions that can be directly used for production, making the upstream and downstream of the industry chain directly docked, saving time, money, and products.
In recent years, integrated circuit manufacturers have been able to make integrated circuit new products into mass production applications in a short period of time, shortening the customer's design cycle, and as the upstream enterprises of R&D and production integrated circuits have stepped up their efforts. The development of the system application program on the product application side adopts the turnkey project mode, so that the downstream terminal factory that purchases the main chip can directly produce according to this scheme in a short period of time and can be listed in a short time. LED driver IC manufacturers provide LED lamp manufacturers with direct production for various types of LED lamp production solutions, as well as DEMO and circuit diagrams and bills of materials (BOM), which has become the upstream enterprise and final product for the production of integrated circuits. The inevitable trend of downstream enterprises to cooperate more closely, to survive together, to develop together, to prosper and prosper, and to win together.
The price of integrated circuits follows the market rules of the pyramid. The integrated circuit products have entered the natural law of constant price reduction since the day of birth. It is precisely because of the price reduction that the space for survival will continue to expand. LED light source and driver IC are also integrated circuits, and naturally follow this natural law, which is the fundamental reason why LED lighting can be rapidly expanded in just a few years. Every time an integrated circuit product is lowered, its market is expanded several times. LED lighting is a massive product that enters the human space. It is inevitable that the sales price will go lower and lower. The main raw material of the integrated circuit, silicon, is everywhere in nature, and it is huge and low.
