LED lighting industry is developing rapidly. 2010 LED lighting starts to ferment, market demand for greatly increased compared with 2009, do the LED packaging, LED display enterprises also have to enter the field of LED lighting. The only LED packaging enterprises in the Chinese market ha s been very little, most of the companies have to do packaging development and production of LED lighting products. LED application areas of business boundaries are increasingly blurred, the enterprise LED product line becomes longer. Although the technological level of the LED products compared to previous years the level of technology has been greatly improved, but most companies dominate the market price at the expense of the quality of the product, also led to a gradual decline in product margins. But already a lot of LED companies began to increase R & D investment to the development of high technology, high value-added, the product of intelligent direction. In the package and the application side, some of the products of individual enterprises and international LED manufacturers competing against. Even so, the LED chip companies overall profit. downlight led chip companies on the overall vote [Us News] into a l arge LED chip industry sales in 2009 of just over 20 billion yuan, and most of the LED chip companies with negative profit or no profit. LED chip companies by the end of 2009 amounted to 62, with the introduction of the technology of large-scale input of the LED chip companies and Taiwan, it is expected that the LED chips in the next few years, China will have a very large development.


Occupy an important position in export, the weak domestic market, in particular the Pearl River Delta region of the LED business, many companies export accounted for more than 50% of the proportion. Mainly because the price of LED products for Chinese consumers is still relatively high, LED application product sales are mainly concentrated in the commercial lighting and municipal engineering, general consumer acceptance is still at a low level. LED inter-firm merger is very rare. Currently on the market there is little between the LED business merger situation, the basic expan d the scale on its own. Compared to the thousands of enterprises on the market, the proportion of mergers between firms is negligible. The main reason is that the LED market is still immature and fully competitive, most businesses can find their own living space. However, the enterprise is very large relative to the small number of merger and reorganization, China LED industry each year to enter and exit.


Corporate proliferation of the lack of leading enterprises


The theme of environmental protection and energy conservation for the commercial led lighting industry, the LED lighting business can be said that the proliferation of a new technological breakthroughs, investing in LED technology lighting springing up everywhere. According to statistics, the annual output value of China s LED industry, billion enterprise has more than 140. With so many brands, but the lack of lea ding enterprises.

Incandescent bulbs per watt to produce 10 lumens, LED manufacturers claim per watt LED lamps can achieve up to 100 lumens. However, the limitations of the shape and maximum working temperature LED difficult to realize its full potential. Performance of the best LED replacement lamps, the efficiency can reach 50-60 lumens per watt. Therefore, LED lamps, CFL lamps in terms of efficiency standards have been equally matched (Note: CFL lamp efficiency range of 60-70 lumens per watt, and the limited potential for improvement).


Ecological problems are also increasingly subject to public attention. With the increasing awareness of environmental issues of global warming and climate change, the idea of ??saving resources and energy is becoming the main points of the marketing strategy. Reduce vehicle fuel consumption and the incandescent lamp is disabled in the past 10 years, a good illustration of this trend. The global multi-national government has developed the incandescent phase-out schedule. Some public policy specifically for energy saving and environmentally friendly "eco" products to provide generous tax support or other financial help.


The inherent advantages of LED s is very eagerly looking forward to meet the publ ic safety, energy saving and environmentally friendly lighting solutions. LED, there are many other advantages such as higher dimming capability, long life and smaller form factor size, shape, color, life and cost to open the door.


LED lighting solutions in all aspects of mechanical, optical, electrical and thermal-compatible alternative to traditional lighting sources (fluorescent lamps, CFL energy-saving lamps, halogen or other incandescent) is an industrial change. Business, office and residential lighting market calls for high quality downlight led modified fixtures. Although cost is still a major obstacle for these solutions, but also need to pay attention to the following technical issues:


[1]. Electrical compatibility with the existing infrastructure, particularly in the use of standards into the wall socket dimmer.


[2]. Shape shall be screw type


[3]. LED heat problem must be solved


1.1 dimmer compatibility


At present, the family, hotel and office space, lighting control equipment are designed and installed for incandescent. Dimming function best approach is to use the electricity cut phase dimmer. The dimmer principle developed for the incandescent lamp power supply. From electricity, incandescent can be regarded as a resistive load.


Electronic lighting source (such as CFL energy-saving lamps or induction lighting lights) electrical equivalent load is no longer a pure resistive load. So that the dimmer work on very different. Improper load use will cause the system malfunction may be very uncomfortable flashing, and even damage to the fixture or dimmer. This may lead to user dissatisfaction, thus postponing the adoption of LED solutions. At present, the dimmer is still expensive and difficult to install. Ther efore, the introduction of high-quality solutions compatible with existing dimmers to honor the commitment of LED lighting to promote the inevitable.


Phase cutting dimmer different types, but the working principle is basically the same (ie, cut off some of the power sine wave in each cycle). This can be done through the switch. Switch is turned on, the power delivered to the load (light bulb). Switch is off, no power supply. By adjusting the switch on time, you can adjust the total energy delivered to the load.

dimmer into two categories: the forefront of cutting-and tangential phase-type.

[1]. Cutting-edge phase cutting dimmer is the beginning of the half-cycle power cut. After a period of time corresponding to the location of the dimmer switch only turns on for the end of the load power supply up to half cycle. After 0:00, repeat the same operation.


[2]. Tangential phase dimmer switch is in the beginning of the half cycle conduction downlight led after a period of time corresponding to the location of the dimmer, and disconnected to keep to the end of the half cycle. After 0:00, repeat the same operation.


To complete the cutting phase, the main use of two technologies: TRIAC (triac) switch or transistor switch. TRIAC dimmer and more cutting-edge phase cutting dimmer. Transistor switch can be either the forefront of cutting phase dimmer can also be tangential dimmer. TRIAC dimmer problem is that it needs to meet the special conditions to work properly: TRIAC can trigger the gate to open, once activated, still needs a minimum current to maintain its conduction state. The trigger current is called "latch-up current, and in order to keep the TRIAC conduction current must be loaded for some time. Once the device latch must have a continuous supply of cur rent. This current is called the "keep current" if the current is broken or weakened, TRIAC will turn off. For compatibility with dimmers, LED lamps must be required to maintain current absorption dimmer. For example, if a 6W LED lights (roughly equivalent to a 40W incandescent bulbs) with a minimum load 10W dimmer with use, you need some additional circuitry to provide sufficient current to maintain. In this case, the light bulb efficiency will be reduced, compared with 40W high efficiency. Without this circuit, commercial led lighting lights do not work properly. Dimmer to keep current. Therefore, the greater the additional loss, better compatibility dimmer. Dimmable applications design difficulty is to find the best trade-off between the luminaire efficiency and dimmer compatibility.

In many cases, the LED higher efficiency can reduce power consumption by up to 88% They also greatly reduces carbon dioxide emissions caused by the lighting and power generation and transmission of electrical energy. The StrategiesUnlimited the co mpany s research, to 2012, total high-brightness white LED lighting market is expected to exceed 50 billion U.S. dollars, and corresponds to 28% in 2009-2012 compound annual growth rate (CAGR). This is just the beginning, because of the commercial / residential lighting market from incandescent, fluorescent and high pressure sodium, high-brightness white LED at the same time continue to accelerate the improvement of LED luminescence efficiency, led light bulbs for home from a commercial point of view, even become more has cost-effectiveness.

LED lighting can make the current global total energy consumption savings of up to 10% according to some calculations, the shift from traditional incandescent and fluorescent. To accelerate efforts to reduce carbon dioxide emissions from electricity generation, the global lighting energy demand is reduced by 10% of the potential This shift has played a gre at role.

What factors support such a huge potential for growth? First of all, this generation of LED luminous efficiency than incandescent, 10 times higher, is more than twice the fluorescent lamps and high pressure sodium (HPS), which greatly reduces the power to provide the required light output (lumens measure) necessary. With the further development of the LED, they rely on the power light-emitting efficiency will continue to improve, and is expected to double within the next few years.

Secondly, in a very environmentally conscious world, LED lighting does not require processing, contact and clear toxic mercury vapor in fluorescent lamps. Today, the cold cathode fluorescent lamp (CCFL) for most residential lighting systems containing up to 5mg of mercury, more lights contain mercury much more!

Third, the incandescent lamp every 1,000 hours need to be replaced, while the fluorescent sustainable use of up to 10,000 hours, compared to the li fe of LEDs over 100,000 hours. In most applications, this enables the LED to be permanently embedded into the final application being without the need for attachment.

Examples include indoor and outdoor commercial and residential lighting, such as street lights, indoor and outdoor industrial lighting, such as power plants and refineries, and other lighting in hazardous environments. 24 hours of uninterrupted operation of some applications (such as refineries), outdoor light fixtures will last up to 11 years, which means they will not require replacement. In addition, LED than several other types of lighting, small and flat-position can be manufactured to very flat form factor, so they can be permanently placed in the internal and external applications.

1, heat


Poor heat of the LED is well known, will inevitably bring the wick life. The design of the existing garden led lights lights tend to heat difficult to meet t he requirements in the field of a heat dissipation is very demanding, but with very poor passive cooling, and is air-cooled, or even a closed air-cooled. As some lamps with plastic sleeve between the driver board and the aluminum heat sink to increase the reliability of insulation, irrigation cooling silicone to increase the cooling capacity. T8 lamp tube is closed, the wick can only rely on air convection heat transfer to the lamp on the back of the aluminum tubes for cooling. General, the internal temperature of these lamps will have seventy to eighty degrees. And if we take into account the heat, weight problems; take into account the weight, heat dissipation is difficult to guarantee, this dilemma of choice in the existing design, there is no feasible standard.


2, life expectancy


LED wick life was index decreased; electrolytic capacitor temperature is increased by ten degrees lower life expectancy in half; the MOS temperature, resistance increases, loss increases, the temperature will rise (constant current mode) with increasing temperature, and ultimately burned . Of course, the domestic manufacturers did not give a specific LED lamp life, and propaganda of the time just mentioned LED wick life of 100,000 hours LED life of bottlenecks in the system driver board LED wick is not damaged, the system drive has hung up.


Another LED light decay is very serious, so the life of the lamp should also consider the visual experience, after how long the brightness of the lamp to reduce the dark feel to the visual extent that life, and customers will consider the replacement of lamps, this life is that manufacturers do not have to come out (or there is no way to give), but it is very important.


Again, the majority of LED home lighting by size limits, protection is difficult to do well, in the voltage fluctuations, severe interference region, the existing low-power design is a test.


Most important, the life of the LED and the company s life is proportional to two years if the publicity 10 years of LED lamps bad six months ago, the company has closed down, the user will take the risk?


3, the weight


The screw interface lamps, fluorescent light weight of only one of the LED lamps, due to the heat sink, the weight of the fluorescent lamp holder who can be negligible, but the weight of the LED lamp holder is a very serious test, particularly the 7.8W spiral interface outdoor light fixtures lights, its weight is very dangerous, which is what businesses have to consider?


4, the price


The LED driver board in the temperature of 70 degrees may be a life of only five years (home), far from reaching 10 years of "concept" of the LED wick compared to the same brightness of the fluorescent, even fluorescent la mps for only one year life. 1W1 element of fluorescent lamps is much much more cost-effective than the 1W10 $ LED. Damage to the LED lamps are often the wick is not bad, have the entire lamp replacement. Calculate the tenth driver board have to discard the remaining nine tenths of the lamp (wick and the heat sink accounted for most of the cost of the entire lamp), if each vendor did not do a good job recycling customers do not like the product.


5, efficiency


Some people may be very strange, LED energy-saving products, why should consider the issue of efficiency? I mentioned here a PF value, a system efficiency. As the majority of the existing LED design are low power, cost pressure to the use of passive PFC (valley-fill), the PF may be up to 90, far less than the efficiency of active PFC easily 99 countries replaced with LED very close to the luminous efficiency of fluorescent lamps is a pressure.

And implementation of low-carbon economic policies of our government in 2010 following the Copenhagen conference, unwavering in two sessions after the launch of the Eleventh Five-green lighting development plan, making the LED semiconductor lighting industry quickly became a courtesan of the lighting industry, lighting companies have sniffed out the power of energy-saving subsidies and market. However, the development of the semiconductor chip technology is still in the stage of development, high-tech equipment and high-end talent prohibitive for many small and medium enterprises, the Shanghai World Expo and Guangzhou Asian Games venues, the project became Philips, Osram, NVC, Op, Huayi garden led lights corporate "patent".

The lighting industry this year seems to be the "nouveau riche" around the city lighting have listed Shilihe, Beijing, Wuhan Han Dynasty to the glory of Chongqing, Nanchang, Lights and so on. It seems that the road of the brand lamps slowly fade over the years the formation of monopoly necrosis brand sales model and it was "blocked" you?

The general manager of the Arts lamp Master Cheng said, although currently the LED semi conductor lighting is extremely strong, however, 70 percent of China s LED lighting companies mostly placing him downstream. Brand lighting, most of the times of active research and development, and design of LED lighting. This also marks the lighting industry, the light source as a starting point through the application of new light to reach the lamp from the shape, are leading the trend to light. While lighting the city to provide consumers with a broader brand lamps, quality, price, selection, with the internet e-commerce, activation, and active in the consumption pattern of the lighting market. However, high consumption of middle and low lighting, so that consumers care about the lamp after-sales service system, Although many lighting the city is committed to a one-stop supplier, one-stop service, but the difference between the grade messy lighting brands, quality, incomplete, accessories far, many consumers are still difficult to see the consumer advantages of lighting the city.

Lighting within the expert analysis, with the subsidy policy of the national energy conservation, improvement of living standards of rural lighting market has been opened, the lighting monopoly has become the best business model in rural and urban areas. As the lighting design, the shape of personalized, lamps, installation, maintenance becomes a very professional and the lamp consumption is no longer limited to the price, more consumers to pay more attention to after-sales service. Store for its professional and systematic after-sales service system, high-, mid-range lighting consumers have more trust stores.

LED lamps across the lighting industry, natural or product quality, brand high bay lighting and the Renaissance, and after-sales service. From China s economic development situation, the future of lighting stores will long endure. Brand building, will be the biggest motivat ion of lighting business development. How to build a good brand which requires enterprises carefully crafted and rich corporate culture and the spirit of accumulation.

For example, collected high-intensity gas discharge lamp (High-intensitydischarge; the HID) and halogen lamps to achieve high brightness, high illumination, the general store for a long time lighting, most of the choice of fluorescent tube ( CompactFluorescentLamp; CFL) lamps, residential multi-use incandescent lamps, fluorescent lamps (CFL) or energy saving bulbs, incandescent lamp power consumption is highest, because the runtime a lot of energy into useless heat dissipation for the life of the lamp will thus appear that compared to other lamps more short.


From the specific application, the areas covered by the general lighting market is very broad, including architectural lighting, signs, landscape lighting, retail, lights, street lighting and residential lighting. In the general lighting market, commonly used light sources including incandescent, compact fluorescent lamps (CFL), linear fluorescent, high intensity gas discharge lamps (HID) and a novel high-brightness light-emitting diodes (High-BrightnessLED; HBLED) and so on.


To discuss the differences in energy-efficient, it is necessary to set out a systematic, scientific assessment method for existing lamps, As to the imp ortant metrics to measure lighting is the input power and lumens. Performance measured by lumens per watt, multi-adopted benchmarks as (energy efficiency, efficacy) assessment, such as lumens per watt (lm / W) to compare the differences in the lamp.


To view the different lighting options, you will find on the poor energy led light bulbs for home of incandescent lamps to 60W incandescent, incandescent energy correction rate is relatively low compare CFL fluorescent energy performance of the relative weakness of many, because the 60W incandescent light of energy efficiency of about 10lm / W, compared to CFL energy efficiency of fluorescent lamps can reach 50lm / W. In contrast, this contrast is the HID one 100WHID can have 80lm / W, a considerable in produce 8,000 lumens of brightness.

First, the energy conservation


The research data shows that LED cold light source, semiconductor lighting, no environmental pollution, compared with incandescent, fluorescent, energy-saving efficiency can reach more than 70%. The same brightness, power consumption is only 1/10 of an ordinary incandescent lamp, fluorescent tube 1/2 if 50% of the LED to replace traditional lighting a year of electricity savings is equivalent to one of the Three Gorges power plant generating capacity the sum of its energy efficiency is very impressive.


Second, health


LED is a green light. DC LED lamp driver, no strobe; infrared and ultraviolet components, there is no radioactive contamination, the color is high and has a luminous directional; performance dimming, color temperature change does not produce visual errors; cold light source low in calories and is safe to touch; These are incandescent and fluorescent reach. It can not only provide comfortable lighting space, but also good to meet people\\ s physical health needs, protect their eyesight healthy and environmentally friendly light source.


Due to the small single LED power, the lower brightness, used a lone sometimes can not achieve the lighting levels, while more than one LED assembly designed to be a practical LED lighting has a broad application prospects. Lighting designers can determine the shape of the lamp optical system, LED number and size of the power needs of lighting objects and luminous flux; can also be a number of LED LED combination of design into point source, the ring light or area light source, a \"second light sources, combined into a \"secondary source\" design lamps.


Third, the art


The light color is to constitute the basic elements of visual aesthetics is an important means to beautify the room. The selection of the light source is a direct impact on the artistic effect of the lighting, LED light color displayed on the display lamps art unparalleled advantages; color LED products cover the entire visible spectral range, and the color is good, high color purity, red, green select the yellow LED combinat ion of color and grayscale (16.7 million colors) with greater flexibility. The lamp is a luminous sculpture constructed of materials, structure, shape and texture lighting material form, show an important means of art. LED technology allows organic combination of scientific and artistic living room lamp, breaking the traditional lamp Collage frame, beyond the inherent concept of the so-called lamp shape, lighting design in the performance of visual perception and forms of artistic creativity, a new perspective to get to know, understand and express the theme of light.

White LED from birth to now, the rapid technological development, enhancing performance, doubling the costs continue to decline. In recent years, many parts of the LED application in the field of functional lighting, C hina s semiconductor lighting applications market is gradually walking in the forefront of the world. Under the policy support of state and local governments in many parts of the gradual application of LED outdoor lighting (eg street lighting, landscape lighting), interior lighting (such as subway, underground garage, museums), the lighting for special occasions (such as the miner s lamp lighting, automotive lighting) accumulated successful experience. However, due to the variety of led landscape lighting products, the differences of technical standards and evaluation methods are inconsistent, the emergence of a variety of issues, some of the lessons of failure, the application prospects of LED interior lighting also attracted the voices of doubt. Nevertheless, we still see many of the traditional lighting companies began to gradually transition to invest in LED lighting, this is undoubtedly a fancy to thi s huge market of LED interior lighting. Insiders also said that after 2010, LED lighting in the home to occupy a larger market share, no doubt about the broad prospects.

LED interior lighting advantage of many

LED brightness and adjustable VIS color, to meet the requirements of interior lighting color atmosphere, in the development of the field of scene lighting market is difficult to compare the advantages of traditional light sources.

Dynamic control of the LED s are easy to design cluster control according to the needs of users, in some occasions need programmability, LED intelligent products can provide a range of solutions. For the intelligent management of indoor lighting provides a convenient, but also can make the initial investment in high cost disadvantage due to the use of LED lead.

LED compact, lighting design and building organic integration, so as to "see the light but not light" effect. LED long life, no me rcury, the excellent characteristics of energy saving and environmental protection in line with the national energy policy needs. From the luminous efficiency indicators, led mr16 bulbs lamps have twice the energy-saving lamps, far more than incandescent and halogen lamps.
