LED lighting LED 2010 new energy saving trend

In 2009, LED lighting industry did not have a negative impact on the global financial crisis, the government policies, coupled with the impact of the LED luminous efficiency and overall product cost reduction and other factors, LED lighting industry continued to rise. At the same time the green economy, low-carbon economy has become the focus of global concern; the market of energy-saving products grow with each passing day solar / wind power and other new energy sources, the demand, it also brings the opportunity for the reform and innovation of electronic components industry, but also broaden the space related power device, driving circuit, power supply module, thermal management, connector product.

Lighting

In the Ten City million light driven by the project, the national street lamp and 24 hours of continuous use of the tunnel lights to become the first replacement of key projects, several major cities in the subway also started to popularize LED fluorescent lamp energy projects. Double pull technology and market, created a number of emerging enterprises LED lighting industry chain, according to the latest data show that Shenzhen city LED the number of enterprises by 2007 700 more than 09 years, the rapid development of the more than 2 thousand.

Estimated 2010 to 2011 will be the two year of rapid growth and popularity of commercial lighting LED. In promoting the use of efficiency, energy saving and environmental protection factors of long-term, commercial grade LED lighting system with high lumen output increased significantly in 2010 will, such as parking lot lighting, office lighting, factory lighting, lighting and other areas of the warehouse. In addition to the high brightness and high throughput LED another key application growth market, will be flat-panel LCD TVs, laptops and notebook computers in the display of large size LCD backlight. Some research institutions predict that the LED industry is about to enter a new expansion period, the next three years will be more than two digit growth rate of more than 15%. This growth will stem from more high brightness (HB) and high throughput LED into a new generation of lighting applications. At the same time, the light efficiency of LED lamp has reached 132lm/W, the whole lamp efficiency up to 70-80lm/W; the cost aspect, LED lamps have been in high pressure sodium lamp can be predicted, not much difference between the luminous efficiency, improve cost reduction and promote LED street in 2010 in various fields display skills to the full.

The lighting industry the pace of development doesn't stop there, the luminous efficiency of more than 100 lumens per watt high throughput LED bulb, and allows the LED to use in AC inverter does not need under the condition of creative design, is pushing LED closer to the general lighting market is the mainstream. ISuppli predicts that LED bulbs will truly enter the residential and corporate general lighting market in 2010. There is no doubt that LED's long-term future lies in ordinary lighting.

Lighting industry continues to heat up, in addition to LED luminous efficiency and cost of the factors, the most important factor is the promotion of energy conservation and environmental protection of the new energy industry increasingly attention and support. Whether it is the closing of the 09 world climate conference in Copenhagen, or many countries in the world to deal with the current financial crisis, an important measure to support the development of new energy has always been a decisive position.

All the signs indicate that the new energy will be a technological revolution in modern low-carbon economy. It can be predicted that 2010 will be a year of new energy development. The future of new energy industry value chain will focus on new energy sources and new energy use, more effective collection and development of new energy applications will open up new value growth for semiconductor manufacturers. Such as LED lighting, solar / wind power, electric vehicles and more new applications.

2010 new energy for electronic components of the new bright spot and new applications, in the field of solar / wind power and other fields to explore technological progress and market demand caused by changes in the demand for electronic devices and the latest challenges.

Wind power: 2010 new opportunities / new challenges

Among all kinds of renewable energy, wind power is the most competitive in terms of technology maturity and construction feasibility. In the long run, the prospects of the global wind energy industry is very optimistic, the government has introduced policies conducive to the development of renewable energy incentives for the industry to bring huge market opportunities. Deutsche Bank Research Report released the latest show, global wind power development is entering a period of rapid expansion, the wind energy industry will maintain an annual growth rate of 20%, is expected to 2015, the total output value of the industry will be increased to 5 times the current level. Such a huge demand and market for semiconductor companies to provide new opportunities and challenges.

Because the wind energy is a kind of very unstable energy, the output voltage, frequency and power of the fan are very unstable, so it can not be directly input into the power grid without processing. In the process of wind power generation and grid connected operation, rectifiers, inverters, thyristors, protection devices, transformers and other devices play an important role.

To achieve a large wind farms and the existing national grid usually consists of the following parts: wind turbines, rectifier, inverter, controller, thyristor, synchronizer, lightning protection devices, transformers, connectors and other control systems.

The rectifier is used to convert the alternating current generated by the wind turbine to direct current, so as to reduce the loss of the electric energy in the transmission process as far as possible. Near the end of the grid inverter, then the DC rectifier can come into power grid using sine wave, and then through the thyristors and AC grid generation and synchronization to ensure synchronization of the sine wave alternating current to the power grid and.

The inverter is usually composed of a IGBT module, a freewheeling diode and a IGBT gate driver,
