LED navigation energy-saving carbon reduction lighting technology rapid development

With the global governments in green energy conservation and environmental protection to reach a consensus on the future of green energy saving and related industry prospects bright. In 2009, LED lighting industry showed no signs of a global economic crisis was significantly weakened, vigorously promote the Chinese government, China LED lighting industry is quick to take the heat, in 2009 became the first year of LED lighting, rapid growth and improvement of China LED lighting industry chain in the economic crisis, the rapid development of a new generation of lighting technology carbon reduction LED navigation energy saving, LED lighting industry chain led to tens of millions of businesses thriving.

LED light source high efficiency and no carbon emissions

LED light source is a new generation of solid light source, LED light source as a green, energy saving, electricity saving, long life of the fourth generation of lighting lamps and a sudden emergence of widespread concern, the rapid development in full swing. LED light source as the fourth generation of new energy-saving light source was born to be used to make all kinds of light source. As the light source, the luminous efficiency of incandescent lamp is only five percent, while the luminous efficiency of LED is almost close to ninety percent. LED lighting with its high energy saving, long life, the advantages of environmental protection has become the focus of attention. In recent years, LED high brightness light source because of its manufacturing technology, and the production cost has steadily declined, now almost all of the lamps can be used as a light source LED light source with high brightness, high efficiency and energy saving, no carbon emissions.

LED light source needs to drive IC

The current DCLED light source is a low voltage (VF=2 - 3.6V), high current (IF=200 - 1500mA) working semiconductor devices, must provide a suitable DC constant current to normal light. DC (DC) drive technology of DCLED light source is more and more mature, because we are using the daily lighting power supply high voltage alternating current (AC100-220V), it is necessary to use a step-down technique to obtain a lower voltage, is commonly used in switching power supply and then step-down, alternating current (AC) transform into DC (DC). And then the driving IC transforms into DC constant current source to the LED light source. Therefore, the application scheme of DC drive LED light source must be: switching power supply + constant current source. LED lamps are bound to have a certain space to install the power module, but for the E27 standard screw mouth lamp is very limited space, it is difficult to place. Whether through the transformer or rectifier + switching power supply pressure, loss of the system will have a certain amount of DCLED lamps in between AC and DC power conversion is about 15 ~ 30% of the power loss, the system efficiency is difficult to do more than 90%. If you can use AC (AC) direct drive LED light source, the system will greatly simplify the application program, the system efficiency will easily reach more than 90%.

Government to promote the rapid development of LED lighting industry

Looking at the global market, government subsidies to promote industrial development examples abound, such as Germany's solar power to every family is a good example of success. Today, the Chinese government's 21 cities LED lamp is a plan to boost domestic demand and expand the world's largest market in the subprime crisis a good way! In 2009 Chinese government to stimulate domestic demand, carry out the "ten city lights" the popularity of LED lighting and energy-saving campaign, today has made clear the 21 city to more than ten thousand LED lighting lamp, has become the focus of the project first replace the tunnel lights and 24 hours of continuous use of the National Street, Beijing, Shanghai, Guangzhou, the Shenzhen Metro has started the popularity of energy the project of LED fluorescent lamp. Therefore, the entire LED lighting market is further expanded and spread to the world. LED lighting industry to promote the technology and production capacity to the depth of high-tech development, creating a number of LED lighting industry chain of emerging enterprises, creating new job opportunities. Driven by the rapid development of Chinese LED lighting industry, China's LED industry of the middle and lower reaches of the rapid growth in expanding domestic demand, so that all the relative technology of LED lighting industry chain can be obtained to meet the practical application of quality improvement and new development, so that people across the country can be keenly aware of understanding of LED lights, a for a few years after the massive demand for LED lighting into the tens of thousands of households, the favorable Chinese become the world's largest LED lighting production base, at the same time, is also the largest market China LED lighting. This effect will last five years, or even ten years, until the next generation of lighting technology was born. At present, Southern China, East China, North China has been booming LED lighting industry, let us see the spring of information, LED green lighting as the sun rises at six or seven in the morning.

Promote the use of domestic products is the fundamental development of national industry

In the "ten city lights" plan a LED component must attain 6, this is a very good measure, we should work hard, also have the responsibility to improve the localization rate of LED lighting system, we should encourage our national enterprises and our efforts to engineer. LED light source, LED driver IC, lamp modernization, optical design, cooling system... Achieve world-class level. The technology of LED industry in Taiwan has been in the forefront of the world, so our localization should be the concept of Greater China, including Taiwan, Hongkong, Macao, three regions of the product and technology. Domestic enterprises should actively introduce advanced technology, LED Europe and the United States, we should promote more use of domestic products, especially LED related products with advanced technology, Taiwan Hongkong area, parts of our resources as much as possible, as far as possible to improve the localization rate in the product, makes the contribution for the global marketing of LED lighting manufacturing China.
