Talk about LED Tube Light industry

From January to July this year, LED Tube Light industry, new investment of more than 100 billion yuan.

Traditional lights are far less price competitive

Despite the huge investment, but in view of technical problems, that entry is actually about 70% of companies engaged in the downstream packaging and application services, and the two parts of the total profit of about 10% to 20% of the upstream and middle reaches of the wafer and chip business profits up to 70%. Industry sources say that the high-end chips, and now more than 80% from Taiwan or overseas, the core technology at this stage is still mainly concentrated in Japan and U.S. companies.

LED Underground Light account for 40% to 60% of the cost of the chip, the high cost of raw materials and technology, leading to the loss of price competitiveness, the main reason for not successfully enter millions of households. Power than traditional incandescent light LED 5 to 9 times, the cost of traditional lamps are often more than twice the price of natural high. It is understood, however, in recent years, the price of the chip at an annual rate of decline of about 20%. In addition, the company has recently developed a technology that will reduce the cost of nearly Qicheng LED chip, and another company successfully reduced the price of an ordinary LED lamp energy saving lamp level.

In addition to technical improvements, conducive to the development of policy in the “five” plan to promote the next in succession. At present, Dongguan, Huizhou, Foshan, Shenzhen, Dalian, Xiamen, Nanchang, and the development of relevant industries in succession planning. Market rumors, LED industry standards and subsidies is expected by the end of the introduction.

Five non-standard inferior products into products

Some analysts pointed out that the standard in the industry before the inevitable problems are not introduced, the various manufacturers of LED products is different specifications and different ways, reportedly 50% of products on the market there is no standard inferior product.

Therefore, the market began to question the led wall light industry has a bubble of excess capacity began. Experts point out that, LED is the trend will continue, but at this stage LED industry is not mature, real LED lighting market is not started. Local governments have committed to LED lights as a breakthrough, pull the entire industry, focused on the current LED landscape lighting, tunnel lights, street lamps and other lighting products.

Solar Panel resources

At present, China mainly thermal-based power supply, thermal power on the ecological environment, a huge negative impact, with the deteriorating ecological environment, coal, natural gas and other one-time energy depleted, solar power for its green, pollution-free, renewable and other features, a new energy hot spots.
Abundant Solar Panel resources in China, the annual number of more than 2,000 hours of sunshine the area about the country’s total area of ​​2 / 3, in which conditions to develop solar power plants in the desert and Gobi area of ​​about 300,000 square kilometers, accounting for the total of China’s desert 23% of the area, solar power and wind power, biomass power generation is equivalent under the new energy power generation industry, the traditional alternative energy generation has a role in China’s development potential.

Solar Inverter is the use of semiconductor interface photovoltaic effect, the light energy directly into electrical energy of a technology. The key components of this technology is the solar cell. Solar cells in series after the package to protect a large area of solar panels (components), together with the power controller and other components to form a photovoltaic power generation system. Photovoltaic power generation system consists of solar panels (components), controller and inverter has three major components, equipment refined, high reliability, long life, easy installation and maintenance.
Photovoltaic power generation system into stand-alone PV systems and grid-connected photovoltaic systems. Stand-alone PV power plants in remote villages in the area, including the power supply system, solar home power systems, communications signal power, cathodic protection, solar street lights and other battery can run independently with photovoltaic power generation system.

pv module generation is the use of large-scale arrays of parabolic or dish-shaped mirrors to collect solar thermal energy, the steam through a heat exchanger device, combining the traditional turbine technology, so as to achieve the purpose of power generation. The use of solar thermal power technology to avoid expensive silicon photoelectric conversion process can greatly reduce the cost of solar power. Moreover, this form of solar energy and a solar energy conversion of other forms of unmatched advantages that solar energy hot water can be stored in large containers, a few hours after sunset still be able to drive steam turbine power generation machine.
