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.

The price of LED Tube Light

Temperature in the LED Tube Light 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 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 Strip Light 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 Tube 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 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.

Mixing of the three color LED technology, which is based on research to solve these two problems and proceed. Found that with decreasing distance between the LED chip from the mixed light decreases exponentially with trichromatic color powder coated surface concentration increases exponentially mixing effect is also enhanced in-depth study to start Three-color LED chip spacing decreased and concentration increased three-color look for an optimal balance between the point is a solution to the three primary colors of light mixed with the best programs, which make the tricolor white LED as a light source as possible.

At present, China is in the LED packaging industry, though a big country, but far behind in innovation and technology, mixing three primary colors red, green and blue light technology, to borrow the phosphor coated white LED technology, can achieve the perfect white effect.

The Analysis of China’s PIR LED Tube Light industry

Analysis of China’s PIR LED Tube Light industry sustained rapid and stable growth momentum, mainly from the following two reasons: First, the low cost to attract a large number of OEM orders; Second, with China’s economic growth, expanding domestic market. It can be said of all competitors in the global LED eyes, to enter the Chinese market is inevitable, because China is not only the world’s largest producer of LED lighting, but will be the largest market for LED lighting products, and who occupy the right place and LED lighting manufacturer in China local market opportunities will no doubt be made​​.

The current LED Spotlight on the market, not only on the interior lighting rendering the atmosphere, but there are other sources can not match advantage. However, the development prospects for the current, LED lights for the average consumer price is too expensive, and difficult to consume from. According to industry analysis, LED lighting is expensive, mainly in the following areas.

First, the domestic LED industry does not own the core technology. Many high-end LED technology in the hands of European and American countries, researchers, therefore, China’s LED products are just products occupy a minimum share of profits. Because with the continuous development of the LED chip and the development of its extensive use of LED products, the overall cost will fall, but the present, the number of LED chips using imported technology, resulting in cost is very costly.

Secondly, LED Strip Light cooling products difficult. So this feature, so manufacturers in the production of LED products, they tend to spend a certain cost in the production of heat sink pieces. Therefore, to reduce the price of LED products, can reduce cooling costs in this regard from the start.

Finally, because power is the weakest link in LED products, LED products, which accounted for 20% of all costs, so if LED application manufacturers to improve the quality of power management devices, the power management technology, cost control about 5% -10%, so to a large extent, reduce the cost of the cost of LED products.

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.

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.

LED Strip Light production

A LED Strip Light production machinery may be tens of millions of subsidies into the industry through subsidies to survive a few unspoken rules, led the market is not open already overcapacity.
“Fluorescent lamp is still the mainstream product, LED lights though of concern, but the outbreak of the market potential will take time.” Sui China Illuminating Engineering Society President Wang Jin yesterday in the “Bright green lighting forum New Century,” on the Yangcheng Evening News reporter said.

But the manufacturers seem to not wait, generous investment, large-scale expansion are common, leading to rapid capacity expansion in the chain there are signs of excess capacity. The price war comes the smoke is thick. Eve of the outbreak in the domestic market, LED, Led Tube industry is not enthusiastic because of the collapse of individual companies has cooled, disorderly competition but increased.

Also contributed to the current government to encourage chaos in the LED industry one of the reasons. “No country like China, the LED industry for such a big subsidy.” The source said. Jie Peng also said: “The state encourages the LED industry is good, but even a county government building LED Industrial Park to be the case, been little reason.”

The industry believes that, T5 led tube lights industry is still in rapid development period, many small businesses still survive or disorderly competition will continue for some time.

“Most enterprises are loss of the LED project.” These people that “the market has not fully opened, it had already appeared in the case of excess capacity as far as I know, many companies do the traditional lighting of the LED industry into the future, LED projects are basically relying on other projects to support the. ”

It is understood that the introduction of LED over competing investment planning and under construction production capacity has far exceeded the actual market demand, to invest in the hottest of the LED sapphire substrate, for example, its production capacity in the construction of the project 101 million / year, while China’s current actual demand of only 6.85 million, less than production capacity of 1 / 10. And that did not count the number of imports.

The 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.

The cost of LED Bulb

According to the National Development and Reform Commission predicted that “five” period, LED industry is expected to achieve the goal of quadrupling. To the end of 2015, China’s LED lighting penetration rate of 20%. The estimate is more optimistic about the industry in general, is expected by 2015, China Outdoor LED lighting penetration rate of 60% -80%, indoor commercial LED lighting penetration rate of 25% -30% penetration rate of LED lighting, indoor home about 5% -10%, the overall penetration rate of LED lighting in China will reach or even exceed 20%.

The cost of LED Bulb over the past decade decline in annual rate of 28%, the cost of lighting the next 2-3 years is expected to remain around 25% per year rate of decline. The current price of LED lights is also declining, compared with the end of 2010 decreased by 20% -30%, in the commercial area already has significant economic, LED market boom is coming.

In the face of many more good news, lighting industry, research institutions Zlighting that, for each Led Downlight industry chain enterprises, can not be blindly optimistic, the situation is excellent, does not mean that their development will be able to go up, the industry will also be able to escape laws of the market is likely to eventually become the monopoly of several dominant industry, in the current overcapacity situation, how to survive in the future to ensure competitive energy market in the LED can stand out from more than 4,000 enterprises, come out on top , is the key.

Most companies in the packaging stage of processing, lack of technical strength and technical reserves, only the lowest level in the industrial chain, strengthen research and development, investment and money need to invest the time to vote, but it is necessary to do, it will be very easy to fall behind , I think I can safely learn from Japan Canon’s R & D strategy, then Canon would like to develop a home printer, but their strength and technique are not enough, so the eight companies in Japan and cooperation, such as Toshiba, Sanyo, Mitsubishi and other cooperation, co-financing three hundred million Japanese yuan, to the Canon R & D, developed technology sharing with developing markets, access to a win-win situation. LED-related research institutes, supporting businesses, manufacturing companies can force a coalition of technology research, to master the core technology, the basis for further development, to break past a closed, small and complete, the development model behind closed doors, underwear and stronger corporate outreach .

Market share of LED Strip Light are now very small, we are just around the corner market to grab some life and death, I believe that the relevant enterprises, especially the different product lines and applications companies can form a joint fleet, pool resources to jointly develop the market, only the bigger cake, let the market and more people recognize the value of energy-saving LED lights, we can have a larger market share, especially small and medium sized enterprises, through industry associations, or self-built business alliances, LED energy saving lamp market this big cake.
