The domestic Decorative Lamp

Has been developed to support the efforts of the LED lighting industry gradually increased. In 1998, the exclusion of 6 billion yen in Japan started “21st Century Light Plan”; the United States since 2000, $ 500 million to implement the “National Semiconductor Lighting Plan”; same year, the EU has also announced the launch of the “Rainbow Plan.” Despite the early start in the LED industry in China, but government support is not enough, until 2009 the Ministry of Science “City million LED project” files launch, the domestic Decorative Lamp industry will usher in a larger development project launched LED around the race.

As the heat increases the domestic market, LED industry was once caught in the concept of flying, defiant, scarce innovation dilemma. Part of the installation of high-power LED lights in the demonstration project, the result is not satisfactory, one after another night out the lights, life is short, bright enough, maintenance problems and other issues. Already installed solar lights, and later to the thermal power light, highlights the shortcomings of saving money is not festival, a serious blow to the confidence of LED lights around the installation, the LED Strip Light industry, impeding the healthy and rapid development.

Fortunately, the state always to promote the development of LED industry as a strategic direction. May 19, issued by the Ministry of Science and re-launched the second batch of pilot and demonstration projects, LED industry continues to develop a clear strategic direction for the development of Led Tube industry new impetus, the future prospects of the domestic market.

Today, LED industry barriers focused on the high cost of initial installation. In actual fact, LED initial installation price than the traditional high-energy light, but in the long term economic benefits are considerable. In this regard, Group Sales Director Bai Yuxiang German sources to reporters calculations. Bai Yuxiang introduced, compared with the traditional high pressure sodium lamp. If you achieve the same brightness, 200-watt high pressure sodium lamp need, solar LED lights only low-power 20-watt, 10 hours a day according to the lighting needs of the industrial use of electricity one yuan terms, high pressure sodium lamp per year for each tariff 200W * 10 小时 * 365 days * 1 yuan = 730 yuan. The low-power solar thermal power LED lights do not need, you can save per lamp per year on electricity up to 730 yuan. This does not include the initial installation of high-pressure sodium lamp included cables and other equipment needs, long-term need for manual maintenance costs. Solar small power LED is not the cost of laying cables, no manual maintenance costs, no electricity expenditures. “Small solar-power LED with a higher than normal high pressure sodium lamp installation fee, but 2-3 years can recover the full investment.” Bai Yuxiang said.

The global PIR LED Tube Light industry

As history has become incandescent, LED lighting technology has entered the home from the business. “State support for LED lighting technology is very popular, and a Ten thousand ten cities to carry out pilot projects.” Shanghai Electronic Technology Co., Ltd. Ming-Fen Gold List, told reporters. Energy saving LED lighting as a strategic emerging industries, by state and local governments attach great importance.

It is understood, LED lighting is very prominent advantages, LED light-emitting efficiency, long life, the luminous efficiency of fluorescent lamps can reach 2.5 times the incandescent lamp 13 times. Currently, LED lighting technology in the various provinces have been widely used, only the installation of Zhongshan City, Guangdong, more than 8,000 LED lights. In addition, “LED technology content is relatively high, such as light can interact with people, people interact with architecture, decoration is very strong, loved by shop owners.” Yuan Yi create light LED application design staff, told reporters. Energy crisis and energy saving awareness, the global LED lighting market prospects increasingly bright. Double benefits in the market and regulatory stimuli, the global PIR LED Tube Light industry scale showed rapid growth trend.

LED lighting industry, leading to excessive growth of the size of chain defects

LED lighting for the development of China, the investment adviser Senior Fellow in China, He pointed out that currently, China’s LED lighting development in full swing, the number of enterprises to enter the field of linear growth, lead to market chaos. LED lighting used in most business customers, because of its high price constraints in the mass popularity among consumers, if the current price and then reduced by 30% or more, it is possible to make the LED lighting market accounted for more share. So, how to improve the technological content of LED lighting, reduce costs, become decisive key to the future. As the chain between the abnormal development of the more serious disconnect, show a larger effective barrier, saw input, no output. Downstream of blind investment has greatly reduced the market’s profit margins, the more competitive the market may be smaller profit margins, price wars for the development of new industries is extremely unfavorable, to a certain extent, undermine the competitiveness of high-quality companies, and disrupt rank of the market before the competition.

As the world’s increasing demands for energy saving, LED lighting industry, not just the few developed countries and regions, other countries, the demand for LED Flood Light products is also growing. In recent years, the world’s largest lighting exhibition in Frankfurt, Germany can be seen, LED has occupied the position of absolute advantage in the show, all kinds of LED new product after another.

Led tube lights 18w is one of it

Led Tube company

Light-emitting diode (LED) industry event of a cold front. Lead the development of the EU into recession, coupled with the industry standard has not yet introduced, and focus on the development of Neo-Neon LED business issued profit warning, 90% LED lighting business at a loss, suggesting that the industry exists in the undercurrents. Analysis pointed out that LED products varies greatly, but with the standardization and subsidy policies have been put behind and some of the excess products will be eliminated. Led Tube is still the trend, but to replace the century-old incandescent light, a real “Myriads of Lights” is still a long way.

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 lights 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 Bulb , 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.

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

LED Spotlight

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.

High-power PIR LED Tube Light

LED Spotlight is facing the future development of large-scale, the problem is bound to become a hot-skew problems can not be ignored, to address the problem, close to the LED chip with the thermal expansion coefficient of ceramics, can be said to skew responses to heat a very favorable material.

LED heat discharged to the outside to improve the thermal characteristics to convey the past, most of the use of cooling fans and heat exchangers, such as noise and set a lot of space limitations, in fact, include consumers, manufacturers, including lighting, do not want to use the mandatory cooling components, which means that non-significant increase in forced cooling must be designed to frame in contact with the outside area, while improving the package substrate and frame heat dissipation.

Specific measures such as: high thermal conductivity copper layer surface coating to promote the use of far infrared thermal radiation heat deflection thin film, according to the experimental results confirm that use of the deflection of the heat dissipating cooling effect of film, almost the area close to the same thermal film cooling fan If the deflection in the package substrate thermal adhesive film, frame, or to direct smear layer coating on the package substrate, frame, in theory, but also can improve the heat dissipation.

For high-power PIR LED Tube Light package structure required to support the LED chip bonding of micro-cabling technology epitaxy; the materials development, although already high thermal conductivity of aluminum nitride, but the high thermal conductivity and reflectivity of the interaction between the other one has become difficult question, generally believed that if the future to improve the thermal conductivity of aluminum nitride for high-power LED packaging material has a positive benefit.

LED Bulb，As a new light source, LED power supply and drive circuit near with a different fluorescent electronic ballast, LED drive circuit of the main function is to convert AC voltage to DC voltage, and simultaneously with the LED’s voltage and current match. With the silicon integrated circuit supply voltage plummeted, LED voltage more and more of the best in the power supply output voltage range, the majority of low-voltage power IC technology also applies to LED, especially high-power LED power. Furthermore, LED power supply should also be able to use low-voltage IC power output gradually increased economies of scale.

THE PRICE ABOUT LED Bulb

In my mind, led wall light source with the current traditional very different, but we in the application of LED as a light source when the light is always in the old tradition to go, because we used to have the shackles of our innovative LED light source .

I can not say that he is a qualified expert of LED, but I do for most of the LED and some experts on a certain level of awareness is not high, because when they evaluate LED products are always standing tradition angle of the light source to evaluate the LED light source, so I think they are a qualified from the LED brick home.

LED Tube Light is a low-voltage cold-dot semiconductor light source, complete this sentence summarizes the characteristics of LED, and in our product development applications, which is characterized by endless, we are pursuing is the traditional light source, the required goals, which kinds of consciousness no matter right or wrong, but it is fit to the application of LED will have a certain degree of difficulty, the present situation of the integration LED light source, high voltage LED light source, I think this is the stage of product development to a certain level of semiconductor technology, cooling technology reach a certain level, I think that out of the two technologies is inevitable.

LED fatal drawback is that heat accumulated effect, within the 3 mm2 lost more than half-watt power to generate heat (since 1 watt LED electro-optical conversion rate of less than 50%), while the integrated LED exacerbated this effect more so, Even carrying a heavy thermal shell, can not completely solve the LED heat dissipation effect. LED is a point light source, so we source the design basis should be established on the basis of point light sources, on the basis of improved heat and light type of problem, our engineers are currently facing the most critical issues.

Other LED application product development as the development will still go through a tortuous process, this process is undeniable that the technology will have a short-lived (like the Chinese CVD), for experienced engineers in terms of what we have to grasp LED technology is the mainstream, great direction must not change.

I do not think the design is the LED Bulb currently on the market in this way, we can use thermal, optical principles to a consideration of the current section of the technology, learn from the optical hot, mostly not, the biggest problem is that current technology does not for standardization mode, so there is still much room for innovation.

Spoke of standardization, I would say we are counting on other people in a benchmark, our efforts this talent, this is not the correct view, the standard will give you hope and do not bring much benefit, because the standard rules of the game , you can not afford to participate in the formulation of rules of the game, not even think about how much from the rules of the game to enjoy the benefits, so the standards and specifications that are restricting someone else’s, for terms of an engineer should develop a standard to regulate their own first, and then disseminate restrict other people, you are the first “drive.” Standards is a slow process, so you should standardize their products, standardized product design processes, production processes, test specifications, and even the packaging, instructions, you can not do this, hope someone gives you a specification, you can do it?

LED Tube

Solid-state lighting, Desk Lamps, also known as incandescent, fluorescent lighting after the third generation technology, energy saving, environmental protection, safe and reliable, solid-state light source is optimistic about the industry in the next decade to replace the traditional lighting of the great potential of new light represents the future of lighting technology. Development of new solid-state lighting, lighting is not only a revolution in the field, and consistent with the current government’s “building a resource-saving and environment-friendly society” requirements.

Low-power design, 150 hours power only once, lamps provide adequate lighting in case of power as possible. Production of light using semiconductor technology has a very high photoelectric conversion efficiency, providing the power you can maximize become bright. DC power supply, effectively eliminating the additional electromagnetic loss, further reducing overall energy consumption, so that the whole power of less than 7.5w

LED Bulb widespread attention and rapid development, and it itself has the advantages are inseparable. To sum up these advantages are: high brightness, low voltage, power consumption, small size, long life, impact resistance and stable performance. Potential for the development of LED, Shanghai Xing Ma old company as an industry leader in electronics, in the early development of the industry plays a key role. At present, LED is moving higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, full color direction.

Currently the use of LED Tube for some time, in the car lights, flashlights, etc. The application has been received well, but in street lamps and lighting have not seen many applications, this may be a bottleneck with the current technology has not yet completely break a relationship, LED although there are many advantages, but in the intensity, color temperature, and exposure range there are significant deficiencies. Such as high light intensity, but it’s not strong enough to give people the feeling of sharp glare, fluorescent light is far from sorted out than the illuminated area is too small.

White led down light

White led down light ‘s heat into electricity with an increase in intensity continued to rise, LED chip temperature rise will result in reduced light output, so the LED package structure and a review of the material used is very important. Previous LED resin package with low thermal conductivity, is considered one of the reasons affecting thermal properties, so in recent years gradually switch to high thermal conductivity ceramic, resin or metal plate with package structure. High-power LED chips, respectively, of the commonly used methods include: LED chip size, and improve the luminous efficiency LED chips, high light extraction efficiency package, and the high current and so forth.

While increasing the amount of light proportional to the current increase, but the LED chip as the heat will rise. Because the input field in the high radiation intensity saturated and attenuation phenomenon, which is mainly caused by the LED chip fever, so high power LED Spotlight chip technology, we must first solve the heat problem.

In addition to protecting the LED within the LED chip packaging, but also for both the LED chip and the external electrical connections, cooling and other functions. Requirements of LED chip LED package of light can be efficiently obtained from the external, the package need with high intensity, highly insulating, thermally conductive and highly reflex, surprising is recruited virtually all of these features ceramics, ceramic anti-addition and resistance to heat than light degradation of the resin fine.

As a new light source,LED Strip Light power supply and drive circuit near with a different fluorescent electronic ballast, LED drive circuit of the main function is to convert AC voltage to DC voltage, and simultaneously with the LED’s voltage and current match. With the silicon integrated circuit supply voltage plummeted, LED voltage more and more of the best in the power supply output voltage range, the majority of low-voltage power IC technology also applies to LED, especially high-power LED power. Furthermore, LED power supply should also be able to use low-voltage IC power output gradually increased economies of scale.
Power LED light source that affect the reliability and adaptability is an important part of the focus must be considered. At present, China’s electricity is 220V AC, while the LED light source is a semiconductor light source, usually with low-voltage DC power supply, which requires the set of these lights or external AC-DC conversion circuit, to accommodate the characteristics of LED current drivers. Currently selected channel has the power switching power supply, high frequency power supply, capacitor after the rectifier buck power supply and other, according to the current stability of the transient overshoot and security, reliability of the different requirements for different choices.

Led Tube company

Light-emitting diode (LED) industry event of a cold front. Lead the development of the EU into recession, coupled with the industry standard has not yet introduced, and focus on the development of Neo-Neon LED business issued profit warning, 90% LED lighting business at a loss, suggesting that the industry exists in the undercurrents.

Talk about Monocrystalline Solar Modules

Trough Monocrystalline Solar Modules known as parabolic trough mirrors the whole solar thermal power generation system, is the number of parabolic trough concentrating solar collector through the series-parallel arrangement, will focus sunlight on a receiver tube to heat the working fluid, resulting in high-temperature steam turbine generator sets to promote power generation.

crystalline solar panels and solar thermal power generation technologies, and therefore have different application conditions.
First, technical practicability, the development of photovoltaic technology is more mature, technical practicability, but the core technology still lies in the United States, Japan and a few other developed countries. In comparison, solar thermal technology threshold is lower, compared with other countries, China in this area is much smaller gap, through a series of 863 scientific research projects and joint efforts of industry alliances, we have made much progress. For China, the solar thermal power generation in heat storage, cooling, etc. There are many technical problems to overcome.
Secondly, the production of photovoltaic cells (mainly purified silicon) is a high pollution and high energy consumption, it seems clean, the actual impact on the environment greater. The present case, China’s solar cell production, 80% of the material needs to be imported from abroad, while 90% of the products are sold abroad. Abroad on the production of solar cells in China, more than just value the low cost of labor here. Government of the environmental destruction of the tax policy of the pine and punishment of light, making them more willing to regard China as a solar cell production base. In contrast, solar thermal power plant construction and maintenance of the environmental damage is much smaller.

From the layout point of view, Anti-reflection Coating Glass more flexible layout, you can build large-scale photovoltaic power plants, photovoltaic cells can also be installed on the roof, and even mobile devices, and so on. With the development of future smart grid, home solar power generation can be freely combined network, so that photovoltaic power generation will have a better development. The apparent scale solar thermal power generation, power plants larger, the lower the unit cost of electricity. Therefore only suitable for large-scale solar thermal power plants, the land area, capital requirements of a higher scale.
