What They Are:
When electric accepted is anesthetized beyond the alliance of two antithetical crystals ablaze and calefaction is accustomed off. This is the base of Ablaze Emitting Diodes (LED).
However if too abundant calefaction is created the crystals will breach down and in convenance this agency that the ability of an LED ablaze is bound and that they will accomplish abundantly alone beneath an ambient temperature of about 40 degrees C.
Power of LED Lights accessible end 2011
As the accepted is added added ablaze and calefaction is generated but the accepted technology cannot blow absolute calefaction and this banned the ability of LED chips.
For backup bulbs such as an MR16 the best ability is 6 or 7 watts unless automated cooling such as a fan is used.
To get added power, a ablaze applicable can be advised to use assorted LED's or with added busy calefaction sinks that are able to accumulate the LED chips cool. Our a lot of able downlight is 25 watts.
Life of an LED
There are alone a few companies authoritative LED chips such as Cree, Osram, Phillips, etc and a lot of LED ablaze accessories and bulbs use chips from these manufacturers.
The dent manufacturers apprehend up to 100,000 hours activity but this is bargain badly by the accepted activated to the chip.
350 milliAmps will accord maybe 50,000 hours but college wattage units may be applying 900 milliAmps and the activity will be bargain to 20,000 hours. This is the abstract time for the ablaze achievement to adulteration to an unacceptable level, but unless the dent is damaged it will abide to afford light.
Brightness
This is breadth the LED adventure becomes confusing. The bulk of ablaze accustomed off at a antecedent is abstinent in Lumens, but the bulk of ablaze hitting a apparent is depends on the ambit amid the ablaze antecedent and the apparent and is abstinent in Lux.
The LED chip currently acclimated can catechumen 1 watt into about 80 Lumen. Quite generally the ability absent in the disciplinarian is added to the lamp's appraisement so not all the watts traveling into the lamp are getting adapted to light. ie a "6 watt" lamp may alone accept 5 watts in fact extensive the crystal. This is not consistently accepted so a added reliable admeasurement of the accuracy of the lamp is the lumens claimed.
For archetype MR16 halogen backup lamps accord off amid 200 and 450 lumen. For allegory a 50 watt halogen lamp gives off 950 lumen. So about you amalgamation it a change anatomy 50 watt halogen to 6 watt LED bulbs will not accord the aforementioned bulk of ablaze in a room
However if the ablaze achievement is focused into a attenuated axle again the LED lamp can aftermath an breadth with aforementioned Lux as a halogen, so the claims that a 3 watt LED is according to a 50 watt halogen are array of accurate if you alone wish a one beat atom of light.
Use of LED's.
These are acutely advantageous in bartering applications breadth the top basic amount is account by alienated the amount of alteration lamps and top hours acceptance gives accomplished ability savings. The aftereffect time can be analytic short.
For the home LED's are accomplished for use in ambient lighting and garden lighting. They are ideal for amount wells, corridors, and to accommodate affection lighting in lounges and TV areas. The acknowledgment is that the ablaze above is above to halogen lamps Using LED bulbs in accepted garden accessories can abate the ability acclimated dramatically. A garden can be lit with beneath than 100 watts, so the garden or drive lights can be larboard on every night with the ability use of one old appearance bulb. 5 watt LED bulbs can be adapted anon into absolute accessories as the 12 volt wire anguish transformers will accumulation the actual voltage. Alone 5 watt is recommended as added ability will overheat the bulbs in the absolute accessories and could cause them to fail.

OLED Market is Likely to Be the First Year in 2013
OLED in the market from a slow start in 2000. PM-OLED 2004 began large-scale production, the product is applied to the MP3 player and mobile phone sub-panel, when the market is bright, the industry is looking forward to OLED continuation of the LCD development trajectory.
Long ago, OLED is the industry think is the next-generation display technology. However, the reality is cruel, OLED is not, as everyone expected rapid development. But as the technology continues to progress, companies actively involved in recent years, business investment and O increasing the enthusiasm of the LED , OLED market is likely to be the first year in 2013.
Copy LCD development model
OLED on the market from a slow start in 2000. PM-OLED 2004 began large-scale production, the product is applied to the MP3 player and mobile phone sub-panel, when the market is bright, the industry is looking forward to OLED continuation of the LCD development trajectory.
LCD development is the small size of the screen to start. Initially, as the process technology breakthroughs, advances in LCD production line from the 2-generation line to 5th generation line. Subsequently, LCD production line almost every two years on a generation jump.
Initially, because the issue of life, LCD is only used in computer monitors, notebook computers and other IT products. With LCD-generation line is put into operation, the product gradually penetrate to the TV into the home appliance market. LCD small size of production, to the production of large size with only a short period of less than two years, while the product is fully extended, and only less than a decade. At present, the annual sales of all types of LCD almost all reach 200 million units.
OLED in 2004, as applied in the small size of the products, the industry generally believe that OLED era is approaching. At this time, some manufacturers OLED panel after another mass production, 2006 AUO the photoelectric mass production AM-OLED, success will import mobile phone products, but after six months, AUO photoelectric unbearable loss of AM-OLED pressure, announced the stop production. 2007, CMO production subsidiary of AM-OLED odd crystal, successful production of the larger size of the product, and applied to the field of digital picture frames. During this period, Samsung 's specializes in the production of OLED SMD to launch OLED for mobile phones. The end of 2007, the official sales of Sony OLED TV again declared upcoming OLED times. But in 2008, under the impact of the financial turmoil, the major manufacturers of AM-OLED development progress slowed, but continued research. 2009, SMD AM-OLED used in mobile phones, but the market is still not recognized.
Bounce back
The end of 2010, SMD LED turn AM-O applied to Samsung and HTC smartphones. In 2011, SMD continue to develop smartphone applications AM-OLED panel. In the second half of 2011, the four mobile phone companies Nokia, Motorola, HTC, LG launched two AM-OLED screen phone, which makes the AM-OLED market again lively.
In addition, Samsung recently launched the second generation Galaxy Tab AM-OLED is also used as a screen size of 10.1 inches, which show that AM-O the LED involved in the tablet market, product application gradually expanded. 2012 CES show, LG also showcased a 55-inch AM-OLED TV, and volume production is expected in the second half of 2012. One can imagine, companies actively involved in 2012, AM-OLED prices will gradually decline, the accessories will also be applied to a wide range of products.
The future, OLED can be used in the traditional products can be used in flexible displays. Because the product can be rolled up, is even more convenient to carry, the screen size will no boundaries, when the innovative application of a large number of products will appear, this era of digital home is just around the corner.
OLED is a promising future
Currently, in addition to SMD's, almost no other manufacturers mass production of AM-OLED 5.5-generation production line now the most mass production line, mass production in the second quarter of 2011. AUO Solar and LG Display have been declared in early 2011 that each have an AM-OLED production line production in mid-2011 , was postponed to 2012.

High power LED constant current source designed to drive in series
With the advent of high-power LED, general fluorescent or incandescent 5 to 7 times its luminous efficiency, energy-saving effect is very significant. Thus, the high-power LED has broad application prospects. Currently, a single high-power LED has 1W, 3W, 5W and 10W, has been heavily used 1W and 3W high power LEDs, multiple high-power LED series and parallel, the the combination output power reached 70W ~~ 100W.
High-power LED with high luminous efficiency and energy-saving advantages, but inconsistent pipe pressure drop is the need to overcome the shortcomings. Second, poor temperature characteristics of the high-power LED. Tube current and luminous efficiency varies greatly with the junction temperature and ambient temperature changes, which bring inconvenience to use.
High power LED above shortcomings, people use more than two drive options: 1. Constant voltage source driver. That is, using a plurality of LED in parallel with a constant voltage source driver. Thus, since the tube voltage drop of the LED is inconsistent, so that the diode current is inconsistent, so that the luminous efficiency is also quite different. This program is seldom used in high-power LED. 2 constant current source driver. Inconsistent pipe pressure drop of the high-power LED, LED by their junction temperature and ambient temperature influence, so the number of LED series and driven with a constant current source can effectively overcome these shortcomings.
The main features of the high-power LED
Operating wavelength
The operating wavelength of the high-power LED with its glowing colors. For example, cold white LED operating wavelength of 525 angstroms to 600 angstroms, while warm white LED operating wavelength between 525 angstroms to 675 angstroms.
Forward voltage drop
High power LED's forward voltage for each change of 0.1V, the current change of about 100mA.
The relationship of the working current and luminous intensity
The high power LED luminous intensity of its junction temperature and ambient temperature. This is mainly due to temperature increases, the operating current is also reduced correspondingly, Similarly, LED's luminous intensity and its current relationship is approximately linear, and its working current each reduction 100mA for 1W and 3W LED, the light emitting intensity is reduced about 15%.
High power LED series constant current
The principle of the source drive
Currently appearing on the market of high power LED series drive has its limitations, typically three to six LEDs in series, and the number to be sure, can not be any connection. In this paper, an arbitrary (1 to 20) LED constant current source driver program series, shown in Figure 1, the following works:
1W LED, for example, the rated current of 350mA. For some reason, the LED current is reduced, the constant current source circuit of the acquisition to the current value of the change (decrease) after having amplified by U1 transmission to the control circuit. Inversion processing in the control circuit of the sampling signal, the output pulse width is increased. Power tube D5 conversion stage of the driving power of the output pulse width increases, so that the secondary output voltage increases. In this way, the voltage across the LED in series also increases, therefore, the current flowing through the LED is also increased, which maintain a constant LED current. Similarly, if for some reason, so that the LED current is increased, contrary to the control process. Advantages that: The constant current source drives regardless of the LED voltage drop difference Junction ambient temperature changes cause changes in diode current much, can be accessed through the rapid adjustment of the high-speed constant-current source circuit to Maintain constant current LED.
High power LED constant current source
To pay attention to the design of the drive
The design of high-power LED constant current source drives should pay attention to the following points:
1. To select the control of the control chip of the circuit in accordance with the number of the LED series. Because of the number of LED chips required output power is different. Figure 1 ICE 2A165, also choose other similar switching power supply control chip.
2. Switching power supply transformer leakage induction is as small as possible, otherwise the drive will reduce the reliability. Because the leakage inductance of the transformer, switch off instantly produces very high reverse voltage spikes, severe cases may exceed the breakdown voltage of the control switch, leaving the LED chip breakdown, causing the reliability of the drive is greatly reduced. Switching power supply transformer T1 is the key parts of the product, it is necessary to the production of the professional manufacturers.
3. The operating speed of the constant-current source circuit to be fast, so that can make the LED safer. In this paper, series of LED drive any number (1 to 20) of the series, this would require the change of the output voltage of the switching power supply faster to adjust slowly, and may cause damage to the LED's.
Practice has proved that this paper, high-power LED constant current source drives the program is feasible, and compared with other drives, lower cost, which has broad application prospects.

Chinese Industrial Switching Power Supply Market Development Analysis
According to the latest survey report JFUnited Consulting Co., Ltd. (JFUnited) "2007 Chinese industrial switching power supply market research report "data show that in 2006 China's industrial switching power supply market size of $ 6.7 billion; view from the installation of 2006 industrial field flatbed switching power supply and rail switching power supply products accounted for 66% and 34% of the total market size; classification from the applications point of view, the three major areas of mechanical, electrical and rail accounted for 90% of the switching power supply market in the industrial field , two major areas of mechanical and electrical accounted for 80% of the overall size of the market.
Under JFUnited survey report data show that in 2001-2006, accounting for a major share of the domestic industrial switching power supply manufacturers, such as the growth rate of the major manufacturers of Chaoyang, Ming-wai, Heng Fu average between 15% -30%, but from the entire the industry point of view, the industrial switching power supply did not achieve the expected growth rate of industrial switching power supply market growth rate is much lower than in the communications and home appliances, computer field, the 2001-2006 industrial power growth rate maintained at 10% -15 only % increase in range. In addition, JFUnited survey report pointed out that the domestic industrial switching power supply 2005-2006, the overall market growth rate of slightly more than 30 percent are optimistic about the development of the industrial switching power supply market, and in 2007. With the rapid development of the power rail switching power supply module switch, as well as the emergence of new technologies, the switching power supply of the domestic market structure will change, switching power supply manufacturers at home and abroad the expected growth rate is locked in the 20%, JFUnitedthat industrial switching power supply with a flatbed future pace of development will be maintained at about 20%, the rate of growth and the level of development of China's industrial switching power supply is much lower than in Japan, the United States, Europe and other places.
Foreign companies such as ABB, Omron, Siemens, Phoenix and other major rail products production and sales-based representative of the domestic companies such as Chaoyang, Ming-Wei (Taiwan), Heng Fu Dechuang, three groups such as the production of flat switching power supply based. In addition, foreign companies, in addition to electric Shenglan switching power supply and a few other enterprises in mainland China to set up factories, most of the imported form of sales in the mainland, on the marketing model, industrial switching power supply enterprises showed the coexistence of both agents and direct mode.
The survey report data shows that the main enterprise market scale performance switching power supply for industrial use, the top four only Chaoyang a domestic enterprise, while the other three are foreign-owned enterprises (including Taiwan), and the sunrise is not obvious advantage than the other three companies other domestic enterprises are mostly kept at a moderate level. Industry sales volume before four in Chaoyang, electric Shenglan, Ming-wai, Omron four companies market share accounted for the entire industrial switching power supply market share of 48%, indicating that the industrial switching power supply industry market concentration is already high, The development of the market is more mature level of development. The top ten enterprises in the total domestic enterprises and foreign-funded enterprises the total ratio of 1: 1.5. As can be seen, is currently lagging behind in the domestic industrial switching power supply market, domestic enterprises largely foreign-funded enterprises.
Industrial switching power supply on the price performance of the various manufacturers, JFUnited report pointed out that the price level differences between different power supply manufacturers of similar specifications (the same power and output voltage) is large, the gap in the times to ten times ranging; addition, the same company due to the number of certifications and the types of differences, the same specifications, product prices will have a very different, or the same company lead to huge price differences due to the different positioning of product applications, such as the Chaoyang military grade switching power supply industrial grade and commercial-grade switching power supply 1.5 -3 times the price difference.
JFUnited future domestic industrial switching power supply industry key competitive factors analysis in the survey report pointed out that domestic enterprises engaged in industrial switching power supply, there is a gap with foreign enterprises in terms of the overall size of the product and the product range is impossible to take into account all industrial field, strengths focus on their own areas of expertise, such as Wuxi Yufeng focus in the power industry, with international enterprises from the extension of the high-end market to the mid-market, and increase the impact of domestic enterprises, domestic enterprises to keep existing position to become the primary task, whether further market segmentation to increase the advantages of a combination of resources, the biggest challenge for domestic enterprises in the future development.
With the implementation of the Chinese localization development strategy the electric Shenglan, Omron international industrial power giant, and mergers and restructuring of domestic enterprises, industrial switching power supply products in China highlights the advantages of strategic marketing and cost, not only for the domestic enterprises impact, will further to usurp other high-end foreign brands in the field of market share.
From the point of view of industrial switching power supply market segments, electricity, railways, military, aviation and other fields, mainly monopolized by a small part of the power supply supplier, so that the characteristics of the market in the short term will not change much, the terms of industrial areas, involving products and The environment is more complex, each vendor has different proportions involved in the future, as technology and product development of the various suppliers, market share may be a larger change, Industry development level is good or bad development is particularly important for industries and enterprises, with the rapid development of power electronics technology, a variety of electronic and electrical equipment in the field, program-controlled switchboards, communications, electronic testing equipment power supply, power control equipment, etc. are widely used switching power supply, switching power supply showed alternative linear and phased power trend, the future development of space will reach or exceed the expected level, will determine the speed of development and the future trend of industrial switching power supply enterprises.
In product quality and technically domestic enterprises and foreign enterprises can not want to comparable, but because of China's cheap labor and raw materials, products price plays a very big advantage. This makes the overall size of the domestic small private enterprises also occupies 20% of the size, price and cost factors in the short-term is still one of the most important factors of the domestic competition.
Compared to domestic and foreign companies lose a considerable level in the process, the domestic switching power supply enterprises in size and value, compared with foreign enterprises. Also got some independent technical process, but mainly on a small device products. Rely on foreign technology but also in large-scale device chip technically in the Pearl River Delta region, despite a large number of Taiwanese and Japanese companies to establish production line, but the main chip technology or foreign control. Future competition, an independent technology is the key to switching power supply enterprises to master and expand the market.
JFUnited investigation report concluded that the gap the domestic switching power supply enterprises and foreign-funded enterprises also business development capabilities. Most external channel scarce resources, can only wait for customers to come to the U.S. and European companies with more complete and timely demand information channel network marketing ability is far stronger than domestic, domestic enterprises and foreign-funded enterprises, the prevalence of consciousness is not strong, and do not pay attention to the phenomenon of the relationship to maintain customers. Even some small businesses too pursuit of economic efficiency, while ignoring the related services, such as product quality assurance and after-sales service, the enterprise should bear social responsibility. This result must ultimately is The enterprise customer complaints more and more, and finally out of the market. Future competition, marketing ability and awareness is also an important factor of the enterprise development.
Under JFUnited survey report data show that in 2001-2006, accounting for a major share of the domestic industrial switching power supply manufacturers, such as the growth rate of the major manufacturers of Chaoyang, Ming-wai, Heng Fu average between 15% -30%, but from the entire the industry point of view, the industrial switching power supply did not achieve the expected growth rate of industrial switching power supply market growth rate is much lower than in the communications and home appliances, computer field, the 2001-2006 industrial power growth rate maintained at 10% -15 only % increase in range. In addition, JFUnited survey report pointed out that the domestic industrial switching power supply 2005-2006, the overall market growth rate of slightly more than 30 percent are optimistic about the development of the industrial switching power supply market, and in 2007. With the rapid development of the power rail switching power supply module switch, as well as the emergence of new technologies, the switching power supply of the domestic market structure will change, switching power supply manufacturers at home and abroad the expected growth rate is locked in the 20%, JFUnitedthat industrial switching power supply with a flatbed future pace of development will be maintained at about 20%, the rate of growth and the level of development of China's industrial switching power supply is much lower than in Japan, the United States, Europe and other places.
Foreign companies such as ABB, Omron, Siemens, Phoenix and other major rail products production and sales-based representative of the domestic companies such as Chaoyang, Ming-Wei (Taiwan), Heng Fu Dechuang, three groups such as the production of flat switching power supply based. In addition, foreign companies, in addition to electric Shenglan switching power supply and a few other enterprises in mainland China to set up factories, most of the imported form of sales in the mainland, on the marketing model, industrial switching power supply enterprises showed the coexistence of both agents and direct mode.
The survey report data shows that the main enterprise market scale performance switching power supply for industrial use, the top four only Chaoyang a domestic enterprise, while the other three are foreign-owned enterprises (including Taiwan), and the sunrise is not obvious advantage than the other three companies other domestic enterprises are mostly kept at a moderate level. Industry sales volume before four in Chaoyang, electric Shenglan, Ming-wai, Omron four companies market share accounted for the entire industrial switching power supply market share of 48%, indicating that the industrial switching power supply industry market concentration is already high, The development of the market is more mature level of development. The top ten enterprises in the total domestic enterprises and foreign-funded enterprises the total ratio of 1: 1.5. As can be seen, is currently lagging behind in the domestic industrial switching power supply market, domestic enterprises largely foreign-funded enterprises.
Industrial switching power supply on the price performance of the various manufacturers, JFUnited report pointed out that the price level differences between different power supply manufacturers of similar specifications (the same power and output voltage) is large, the gap in the times to ten times ranging; addition, the same company due to the number of certifications and the types of differences, the same specifications, product prices will have a very different, or the same company lead to huge price differences due to the different positioning of product applications, such as the Chaoyang military grade switching power supply industrial grade and commercial-grade switching power supply 1.5 -3 times the price difference.
JFUnited future domestic industrial switching power supply industry key competitive factors analysis in the survey report pointed out that domestic enterprises engaged in industrial switching power supply, there is a gap with foreign enterprises in terms of the overall size of the product and the product range is impossible to take into account all industrial field, strengths focus on their own areas of expertise, such as Wuxi Yufeng focus in the power industry, with international enterprises from the extension of the high-end market to the mid-market, and increase the impact of domestic enterprises, domestic enterprises to keep existing position to become the primary task, whether further market segmentation to increase the advantages of a combination of resources, the biggest challenge for domestic enterprises in the future development.
With the implementation of the Chinese localization development strategy the electric Shenglan, Omron international industrial power giant, and mergers and restructuring of domestic enterprises, industrial switching power supply products in China highlights the advantages of strategic marketing and cost, not only for the domestic enterprises impact, will further to usurp other high-end foreign brands in the field of market share.
