The feature of crystalline solar panels
The two identical crystalline solar panels connected by a certain angle, “people” type, they are both used as photoelectric conversion of the battery, also played the role of photosensitive devices. Vertical sun radiation on the ground, the two solar battery panel to get the energy density exactly equal, the photocurrent generated by the same size, orientation of the electric motor to control them at this time does not work. Incident angle of sunlight changes with the ground, if the panels get a sunlight energy density greater than the energy flux density B to beDegree, the solar panels generate a current intensity of light is greater than the B cell panel on the current intensity of light, use this signal to drive the motor rotation, making the panels and the angle between the sun light perpendicular to the ground with exactly the same. The advantage of regulation is more precise, the circuit is relatively simple, but the angle between the two panels is always there, never to truly vertical.

Solar thermal power generation and photovoltaic power generation than in technical difficulty, environmental protection is superior to the photovoltaic power generation, but in terms of cost control, technology research and development, there is still a long way to go. Solar Modules thermal power generation industry is booming, but the recent domestic solar thermal power generation on two major projects to show us two sides of solar thermal power generation, on the one hand, 10 of 2010, solar thermal power plant tender Erdos, a full seven years of preparation until the bid results were announced in April this year, Tang new Energy Co., Ltd. to 0.9399 yuan / kWh of the lowest bid; the other hand, is located in Badaling town of Yanqing Asia’s first 1-megawatt capacity of the light tower thermal power plants now under construction, total investment 120 million yuan, the Chinese Academy of Sciences, Huang Ming solar Energy Co. and Huadian Group and other units in joint research and related technology has been mastered by domestic technology, heliostats, slot coating steel pipe, tank type condenser can be self-production, and the more advanced level, a bright future.

Anti-reflection Coating Glass is a new product .

The production of LED Panel

“Shuffle is the development of led tube lights 18w blind way of sorting out the best”

Many predict, will close down next year a lot more LED business

Closures, low barriers to entry, subsidy fraud … … in the face of the recent spate of negative news for the LED industry was wearing this huge industry cast a halo of gray. However, at this time, the Group’s investment in wide one hundred largest exhibition and trade platform for LED and lighting — Guangzhou Panyu in Guangzhou Optics Valley recently opened.

For the problems facing the industry, many stationed in LED business, said: “LED Tube industry two years ago really hot, a lot of hot money influx is now shuffling across the industry is definitely a good sign, is the blind before the development of best sort out the way. ”

Ma Ji said: “There is no doubt, LED will become increasingly fierce market competition, but this energy saving lighting products will eventually replace the traditional lighting of the trend will not change.”

“LED products still have to do is relatively strong, focused companies will ultimately win the market.” Began in 2001 R & D and production of LED Panel in Guangzhou Rui Technology Co., Ltd. Managing Director Liangying Yi said: “The first two years of watching LED industry, fire, rush to a lot of hot money, shoes, hat dare to do the production of LED. the industry is indeed a bit confusing for the industry, the impact is relatively large, but this is certainly not a rational price to pay, I have seen Many companies suffer not go. ”

Speaking of closures LED industry, and many harbor businesses will close down next year was more predictable. “But this does not affect the development of high-quality business.” Wide Wu Wenbin, general manager, told reporters on the electrical, the same power of LED lighting products is a traditional product cost three to four times, but the LED on the market a lot of shoddy products do not put so much cost, low-quality low-cost route to enable consumers to take the whole industry a very bad impression, in the end harm or the enterprise itself.

“Guangdong’s total annual lighting industry in China as 40% of the advantages of the region, the establishment of a hub-based LED industry has been imperative.” Yesterday, the Guangzhou Economic and Trade Commission of the relevant person in charge told reporters that the State and Guangdong Province have introduced relevant policy is expected to promote further development of LED industry.

White LED Freezer Light

Temperature in the LED Tube section, the most effective means is to design a high thermal performance of the LED package, which is China’s LED industry in the near future be able to make significant progress on LED intellectual property one of the direction, the LED is a low-voltage electronic products, electrical safety requirements in a more relaxed, so the thermal conductivity of the substrate material can be used more, and we study this industry is small, resulting in repeated breach of foreign intellectual property disputes.

Improve the stability of the phosphor, is the mainstream of white LED Freezer Light technology, in this regard our current technology is relatively weak, short-term progress can not be exceeded for the majority of enterprises to seek a breakthrough in this area is difficult.

Color compensation technology is to compensate for the lack of color LED color rendering index caused a reduction techniques, this technology is feasible from the principle of speaking, but in practice, faced with mixed light conditions the strict constraints of technology , so the practical value is not high.

3:6:1 RGB white line based on the mixing theory, this theory is based on our look at bright objects on the basis of this mixing technique can be successfully applied in white LED display technology, but application in the lighting program on the program this mixing is not much reference on the nature, this is because the human eye to visible light has a characteristic and average characteristics of a habit, and these two characteristics, which we unconsciously damage the eyesight of the important reasons.

Because according to the nature of lighting and clear, light on the object, the object into the eye through the reflection, so as to form a lighting process, as objects of various wavelengths of light absorption is different, so solid red, green and blue color LED 3:6:1 mix through out the white light technology, itself, there are some color defects, exposure to the surface, because the red, green and blue are absorbed by different surfaces, different reflections, resulting in the reduction of CRI . Therefore, a three-color mixing technology and the production of white products, the surface should be in the components or the use of technical means within the product mix of light, so that a white light, rather than sending the light of three different objects in the illuminated surface mixing, the resulting lower CRI.

Red, green and blue color led wall light color mixing technology is a more mature white lighting technology, this technology because the distance between the different LED light mixing caused by the larger distance, mixed with the LED front mask, although the solution of the mixed light problem, but the light loss is an obstacle for the development of lighting in the formation toward the light barrier. Another person when direct lighting is not even watching the white; these two factors directly restricts the development of this technology.

The price of LED Street Lights

Real estate industry due to the rapid development in recent years, improvement of living standards. Many fast-growing brand lighting, lighting the crowd milling around the market for a time. I do not recommend blind investment, high-grade, high quality lighting is the development of the industry the last word. Most lighting companies as a single product, grade poor face elimination, really stylish, energy saving, environmental protection is very little lighting. This form of lighting for a time the market was mixed. Choose the strength of the business cooperation will be effective the lighting market to seize the opportunity to share the key piece of cake. Economic crisis will lead to unscrupulous investment in many industries, the investment risk can be imagined. I suggest that investors need to field trips, do understand the real situation of the company investment plans.

LED Street Lights changes will directly affect the “carbon” output. How carbon, will be lighting quality, long-term development problems. I believe that with advances in technology, market competition lighting, energy saving, environmental protection and lighting will be more and more people all ages. According to industry analysts, the tide of low-carbon economy, energy saving lighting will quickly into the lighting market.

Solar Modules as an “inexhaustible” security, environmental protection and new energy sources more and more attention. In this way, solar lighting products emerged as the popularity of solar water heaters, solar lamps in here and use electricity for lighting the practical effect of contrast.

As the Earth’s resources become increasingly scarce, the cost of increasing investment in basic energy of the rising, and a variety of safety and pollution problems can be described as ubiquitous. After some comparison we find the following: solar lighting safety without risk, no energy consumption, environmental protection, ease of installation, maintenance and other characteristics of automatic control, for real estate sales, construction of public works to bring significant direct effect.

Polycrystalline Solar PV Module is also a good product .

As T5 led tube lights technology continues to evolve, the LED as a light source as possible, because the light source in the lighting fixtures on the color index CRI has strict requirements, and the current color white LED technology in terms of the less mature, making it constraints LED as a light source of the main obstacles.

Composite white light, very easy to break through the prism of white light contains all colors in the light. The LED is a more comprehensive source chromatogram, which features wide color gamut LED lighting products for the high color laid a theoretical foundation.

Just a kind of wave-particle two-phase nature of the substance that contains the characteristics of the wave properties of particles are included, so that it has a strong complex features, so in light of the nature and terms of the characteristics of LED, the a high-quality LED light source as possible.

The current white LED Tube technology, mainly blue-chip production process follow-coated phosphor, this technology was developed by Nichia Corporation developed a certain sense, followed the principle of fluorescent light tubes, this technology because red and green components missing, so that on the existence of congenital color index gap, currently fill the gap, phosphor technology to become the main direction within the industry.

Blue chip manufacturing white phosphor coating technology, which in principle can produce better white light, but in the course because of the ability to adapt to the environment is weak, resulting in differences in theory and practical products, such differences arise largely because the LED heat accumulated on the effects of phosphor produced.

We have had experience, high-power white LED as the work time, heat production and heat loss gradually to reach equilibrium, the equilibrium temperature is higher, for the use of the same type of white LED Spot light phosphors affect the more large.

In the led wall light industry, LED lighting as the “fourth generation light source” or “green light.” Is the “torch to the oil lamp (candle)”, “to the incandescent lamp (fluorescent, energy saving lamps)”, “incandescent to LED lighting,” “the third lighting revolution.” For a long time, European, American and Japanese industry has a monopoly on the most critical white LED, high power LED lamp heat balance, durable and efficient phosphor technology core, the domestic LED industry has been in a passive situation, the requirements of product innovation is very urgent. In the LED industry both on the main direction of research and development of high-power technology, the Texas subsidiary of German energy sword easy road – the main world problems selected small solar-power LED lighting products and the success of mass production in one fell swoop, opened up a small amount of power LED production of its kind. It is understood that the solar low-power LED (0.06W) Product luminous efficiency of up to 90% conversion, heat dissipation is less than 10%, 2000 hours without decay, life of more than 50,000 hours or more, the energy savings to an extreme.

According to the reporter, under the LED Spotlight industry segments, divided into small high-power LED and power LED. Typically, LED lighting currently used by more than 90%, is used as a source of high-power energy-saving lamps. The so-called single high power LED means light emitting diode is equal to the power greater than 1W. Despite the high power LED lighting products than conventional products energy saving, environmental protection, but still small compared to the rival power LED products, need to overcome many of the core technology. It is understood that high-power LED light conversion efficiency is not high, only about 50% -60%, a lot of power consumption on the radiator, this cooling plate from the need to install can be seen. In the actual installation, the power LED, there are many problems to be resolved.

Numerous studies have demonstrated, in the LED lighting products,LED Strip Light power 0.06W maximum luminous efficiency is about the best, that is, low-power LED products. This worldwide problem has been overcome in Texas, a photovoltaic company, a subsidiary of German energy not only has a small power LED full intellectual property rights, is still technically solve the heat, the light fades and other key issues, has become the world’s very few low-power LED patented lighting products manufacturer. Now, the company’s product technology has been developed to eighth. According to the German source group development director Liang Baoqiang description: “the company ninth, tenth-generation products have been successfully developed products in the reserve period. In addition, the combination of solar and wind energy in power generation, solar water system, solar cars and other products also have the use of new research results.

In recent years, raw materials and rising prices of upstream components, combined with increased labor costs, resulting in the problem of rising production costs. Moreover, to enhance consumer brand awareness, distribution channels, the level of fees rising year by year, in the joint action of many factors, many lighting companies have put forward the slogan of the transition.

Personal view is that any lighting companies in the initial stage is to rely on the profit model, which is a necessary process, but after a certain stage of development, in particular, many companies rely on primitive accumulation of capital to complete this model, the simple rely on this profit model, may be able to maintain their status quo sales, but to achieve greater performance, then, was profitable to rethink the issue.

led down light he rapid development of the world known as a sunrise industry. The front-end multi-Jun Li, Shenzhen LED business “on foot” event, and this year more than 80 Shenzhen LED bankruptcy or winding up of the reality, so that a quite popular industry seems to have become a popular “hot potato.” It was in this market context, the development of Shenzhen Great Wall Technology Co., Ltd. (referred to as the Great Wall Development) announced plans to invest nearly 50 billion yuan to build a complete LED industrial chain. The end of the global chip giant has an alliance with other partners in related industries are also actively negotiation.

Build a business overall LED Spotlight industry chain, only the international Philips, GE, Osram such mine. In China, only the Great Wall is being developed by the steady implementation of the blueprint. So, the Great Wall of industrial development in the end judged based on how and advantages of this strategy assessment lock it? Yesterday, the reporter interviewed the development of Shenzhen Great Wall Technology Co., Ltd. Vice President Chen Zhu Jiang. His answer is, if an LED price and the price quite a hamburger, the market demand will be stimulated immediately. Great Wall of development, is to control all key aspects of the industry chain, to minimize the cost, performance and price of both the leading edge of LED products into the global market.

To promote the development of Led Tube industry, enterprises bigger and stronger, should break through the bottleneck of two prominent: First, the core technology and key equipment controlled by others, the second is marketing applications difficult. To this end, LED industry should form a collaborative innovation mechanism, the Government should give some support to their market application.

With the country’s increasing emphasis on renewable pv module energy, solar photovoltaic industry will usher in the peak of its historic development, the development of glass products which will bring important changes. To meet growing market demand, Xinyi Glass will continue to strengthen research and development capabilities, to constantly introduce new products and improve product quality. In the Lutheran Wuhu and Tianjin base will have a new production line on stream in 2011, focusing on the development of new energy and environmental energy-saving glass products to meet the future market for high-quality float glass, low-E glass (LOW-E glass), double layer of insulating glass and photovoltaic glass of strong demand. I believe the future second and third tier cities for quality float glass and the demand for LOW-E glass will show explosive growth.

solar ARAC Glass is mainly used for solar panels transparent glass protective layer, the fundamental and essential for the solar cell material. Lutheran photovoltaic glass production line completely independent intellectual property technical design, but also the nation’s current largest photovoltaic glass production line.

Glass as a high energy-consuming enterprises, has been the focus of national energy saving target. In the existing industrial base, combined with national policy, not limited by line conditions, to achieve sustainable development of the industry, the glass is an important issue facing the company. Develop energy-saving, new energy glass as the holy grail of many companies.

Requirements of national regulatory authorities to promote the development of the enterprise group policies to encourage mergers and acquisitions, project approval, land approval, credit, tax breaks and other aspects of support competitive enterprises, encourage enterprises to reduce the construction of new lines, and more mergers and acquisitions, mergers and acquisitions and transformation through bigger stronger, for the next three years the top 10 largest producers of flat glass industry for more than 70% concentration. Reporters learned that, under the pressure of energy saving, the domestic leader in glass have force of new energy glass products, not only in line with national policy, but also new opportunities for expanded business development.

Dual Axis Tracker is also very important .

According to experts, solar Pv Glass curtain wall is the traditional glass curtain wall and solar photovoltaic technology, combine the construction of a new curtain wall, mainly using a new type of solar power, green energy technologies. Solar photovoltaic glass curtain wall to strengthen the R & D has become the photovoltaic industry, building walls to promote renewable energy industry on the application in the construction of new topics. Shenzhen Chuang Yi Technology Co., Ltd. standardization engineer, said Yang Ge, and electrical design of solar photovoltaic glass curtain wall of mandatory national standards related to 53, but no breakdown of the introduction of relevant standards, lack of international standards designed to make each unit , production units, construction units and so on according to their own experience to design, manufacture and construction, different algorithms led to different configurations, reducing the interchangeability and improve the system design and maintenance costs.

As pv module , not from the construction requirements, including installation, lighting and mechanical properties. Also need to be photovoltaic glass curtain wall components within the current leads, involves junction boxes, cables, controllers, batteries and other devices designed to selection. Large-scale application has not been at home and abroad, to demonstration projects in the country is based.

Production of energy-saving lamps is an important step in effective energy. Lighting industry to go low-carbon economy, we must develop energy-saving lamps production. Energy-saving lamp has significantly improved the traditional lighting of the high-loss problem, according to incomplete statistics, the same power (wattage) lamps, energy saving lamp will save 70% cf light. Unfortunately, because of damaged energy-saving lamps contain mercury, will seriously pollute the environment. However, the latest energy-efficient LED materials, products, pollution, the effective energy saving, energy saving, environmental protection, lighting is a historical necessity.

Experts say, Dragon solar Pv Glass curtain wall is a traditional glass curtain wall and solar photovoltaic technology, combine the construction of a brand new curtain wall, mainly simply by using a new design of do not have, green energy technologies. Solar photovoltaic glass curtain wall to strengthen the R & D has become the photovoltaic industry, building walls to offer renewable energy industry on your application in the construction of brand new topics. Shenzhen Chuang Yi Technology Co., Ltd. standardization engineer, said Yang Ge, and electrical form of solar photovoltaic glass curtain wall of mandatory national standards regarding 53, but no breakdown from the introduction of relevant standards, absence of international standards designed to make each unit , production units, construction units therefore forth determined by most of the experience to design, manufacture and construction, different algorithms leaded to different configurations, lowering the interchangeability and improve the system design and maintenance costs.

Dependent on reports, from your technical viewpoint, Solar Modules curtain wall glass curtain wall an estimated ordinary power function, to make the right application.

As architectural glass curtain wall, not out from the construction requirements, including installation, lighting and mechanical properties. Should likewise be photovoltaic glass curtain wall components around the current leads, involves junction boxes, cables, controllers, batteries besides other devices that can selection. Large-scale application hasn’t been at home and abroad, to demonstration projects in the usa is.

“The next few years, the sector reshuffle is inevitable.” Orient Technology Co., Ltd. Second in command Hanguang Yu also said: “From the perspective of Taiwan’s development process, many LED Street Lights companies last only four. Continent’s LED industry is take this road, shuffling is yes. ”

And in your industry, in addition to has shown the “polarization” using the trend. Global Market Group export monitoring data reveal that the export of real information on the customer viewpoint, although overall for 2011, exports maintained a rise rate of more than 60%, but 20% of your companies to make sure you slow up the strong stronger as well weak weaker situation became clear.

Industry mergers, acquisitions, has additionally staged. Han’s Laser (002,008) Acquisition of the rule of the country star, Yuanheng, Road L; BDO Runda (002,005) Buying of sharp Billiton endless. Foreign giants which can include Philips, usually have accelerated the pace of expansion in China. Many small companies, has grown a considerable business eyeing the “prey.” Lighting, general manager of Dongguan Rui Kang Wenjian star said: “Although which is multi-LED business, fall can’t called a few companies ‘closures’, however, the real ‘closures’ that there will probably be.”
