\"In the first half of last year, the light-emitting diode (LED) packaging industry has been developing very well, but in the third quarter of last year, the industry as a whole the situation worsened in the fourth quarter is even worse. After the Spring Festival this year, everyone feels the game is 2 late May institutions to company research, said that packaging companies in Taiwan are better, ask the company how, then not feel any changes, but in March, the company orders increased dramatically, industry rebound at the same time last year the phenomenon of upstream LED chip manufacturers lower prices, big sale clear inventory trend gradually stabilize chip prices, purchasing chips did not have to bargain. \"

Driving the company\\ s order pick-up, not only the demand from the LED backlight, but also the demand from the field of LED lighting. The case of Ruifeng power industry representative.

An unnamed analyst told reporters that, as early as February, the LED industry has to pick up signals, and significantly warmer in March. First, Taiwan LED chips, packaging manufacturers improved orders, capacity utilization rose. Regional conduction LED business trends on the Mainland gradually. Large-size backlight display shipments to increase, significantly increasing the demand for LED related products.

According to the latest news, Taiwan LED manufacturers such as crystal, Everlight, East Bay, Formosa Epitaxy, etc., will be released later this week February operating income. The industry is expected with the significant increase of the panel backlight and LED lighting needs in Taiwan LED manufacturers in February revenues generally rose 10% to 20%, and expected monthly rise since February to the third quarter. Formosa Epitaxy announced in February revenue of 3.2 billion Taiwan dollars (about 68.45 million yuan), an increase of approximately 18% compared with January. The company said revenue growth was mainly from the large-size backlight orders increase, small and medium size parts rebounded slightly, LED lighting demand is expected to gradually pick up.

Chip corporate pressure still

Relative to the middle reaches of the packaging industry to pick up an LED chip listed companies have admitted that the substantial expansion of the previous two years, \"the pressure of the chip companies is slightly larger.\"

Listed companies have been released by the 2011 annual report also shows that the inventory at the end of the LED chip companies last year compared with the beginning of a more substantial increase, such as 3 An optical inventory at the end of 2011 for 919 million yuan, although higher than the third quarter, a decrease but still the beginning of 310 million yuan, an increase of 195.88%. Silan 2011 ending stocks at 483 million yuan, an increase of 53.91% compared to the beginning of the year.

The analysts said that the LED packaging business is expected to have a pulling effect on the upstream chip business, but the crazy expansion caused by the chip companies based on the first two years of the industrial structure of supply and demand imbalance, he expects this year\\ s chip link supply and demand is still difficult to fundamentally changed, and they would not optimistic about the overall performance of the LED industry upstream.

In addition, the above-mentioned chip listed company said, Although chip prices have bottomed out, but chip prices lower is a long-term trend, product gross margin decline is an inevitable trend. This point in the annual reports of listed companies has been the most direct response. The Silan light-emitting diode product gross margin was 35.65%, 12.41 percentage points less than last year. Also, because the decline in gross margin, the three safety photoelectric chip sales margins fell to 43.47 percent.

But the source also said that chip prices fell, the product cost increase, will eventually be in exchange for greater market space. Domestic LED chip companies competitive space is relatively small, especially in lighting applications, primarily relying on financial investment and financial subsidies to the engineering lighting.

Overall, the trend of the packaging industry orders significantly warmer, LED industry throughout the year to become optimistic. WANG Yu-chun is expected the second half of the situation should be better than the first half of his views has been a lot of industry recognition, the industry is also widely expected to benefit from the rebound in demand for LED backlighting and LED lighting steadily growing demand, the national policy level promote investment in and financial subsidies, the industry throughout the year will show a low after the high of the development trend.

Back to the temperature of the LED industry is expected to the first two quarters

The first quarter performance due to the debt crisis in Europe and the Lunar New Year of factors, Taiwan\\ s LED as a whole does not meet market expectations, the Epistar Guanglei, Thai Valley, the new century, wide gallium and other grain plant and Lite Division, Ding Yuan, East Tony, Nigel David, light tripod stand Acer packaging factory in February 2012, cumulative revenues over the same period in 2011 recession more than 20%.

Order demand of the driven part of the backlight with the Korean series TV brands is about to launch new models of LED TVs, plus the number of days in February increased over January, the majority of manufacturers in February revenue showing the monthly growth trend. Estimates into two quarters, is expected quarterly basis, monthly slowly back to the temperature, but to see significant growth until the second half of the year.

Market is generally optimistic about the prices of LED lighting in 2012 dropped significantly, LED Light Bulb is expected to reach $ 10 sweet spot, Yeyin Fu believes that the rapid decline in market price trend, but more importantly, consumer acceptance, the Taiwan government and manufacturers need more consumer education and energy-saving concept, LED lighting is expected to go to the fourth quarter of this year will take off.

LED general lighting market will phase out low-voltage LED chips

LED general lighting market today is tempt everyone\\ s appetite, has attracted so much attention, no other reason than the following three aspects, first, its market is large enough; the end of this year or early next year, LED general lighting market in the first year will come, that is LED lighting proportion of the total lighting will be more than 10%; with incandescent, fluorescent and energy-saving lamp market is basically a handful of GE, Philips and OSRAM monopoly of suppliers, large lamps manufactured LED lighting accounts for only about 10 percent of the total lighting market, that is, LED general lighting market is not a monopoly market, we all have the opportunity to play inside.

However, today most of the LED chip suppliers face the risk of an out, because the low-voltage LED chips produced today will be increasingly difficult to sell into the LED general lighting market. Why? Because of the high-voltage LED, compared to the high-voltage LED low voltage LED There are two clear competitive advantage:

First, in the same output power, high voltage LED drive current significantly lower than the low-voltage LED. Epistar high pressure blue 1WLED, for example, the forward voltage drop of up to 50V, that it is only 20mA drive current output power of 1W, while the average forward voltage drop is 3V 1WLED need 350mA drive current to output 1W power dissipation of power by the same high-voltage LED output power at work is far lower than the low-voltage LED, which means that the cost of cooling the aluminum casing can be greatly reduced.

Second, high voltage LED can significantly reduce the AC-DC conversion efficiency losses. 10W output power, for example, if the forward voltage drop of 50V 1W high-voltage LED, the output can take two and four-string configuration, four series of LED forward voltage drop of 200V, that is just from the City power 220V alternating current (AC) bridge rectifier and drop 20V on it. However, if we adopt a forward voltage drop is 3V 1W low voltage LED, even if the forward voltage drop of 10 strung together, but 30V, that is to say from the 220VAC mains step-down to 30VDC. We know that the lower the pressure difference of the input and output AC to DC conversion efficiency is higher, can be seen such as the use of high pressure the LED, the efficiency of the transformer can be greatly improved, thereby significantly reducing the power loss when the AC-DC converters, which a heat consumption to reduce but also to further reduce the cost of the cooling shell.

Therefore, if the high-voltage LED to develop LED general lighting products, the overall power consumption can be greatly reduced, thereby significantly reducing the design requirements of the thermal shell, such as we can use thinner, lighter aluminum casing can meet the cooling needs of the LED lamps an integral part of the cost of aluminum casing to reduce also means that effectively reduce the overall LED lighting costs due to the cost of the heat dissipating aluminum enclosure is the major cost of LED lighting.

Thus, high voltage LED can bring to effectively reduce the cost and weight of LED lighting, but its significance is dramatically reducing the design requirements of the cooling system, which will effectively cleared the LED lighting indoor lighting market technical obstacles. Therefore, the high-voltage LED will dominate the future of LED general lighting market.

   March 23, the SFC website disclosed Shenzhen Absen Photoelectric Co., Ltd. (hereinafter referred to as the \"the Absen\") and the gem of the first prospectus.

    The prospectus shows that the the Absen to be issued 2,106 shares, intended to raise capital of 260 million yuan, mainly for the LED display, LED lighting products, construction projects, and LED technology R & D center construction projects.

    However, including the display homogenization intense competition, product prices continue to decline, gross margin facing downside risks to overseas business major, facing the international political and economic environment, the risk of instability, the main business slowdown, the company dispersed ownership structure and many do not determine risk, Absen whether successful clearance, caused by the widespread concern of the line inside and outside.

    LED display industry is highly competitive

    Nearly a year, the LED display is the main business enterprises have to seek expansion transformation of the way to go through the IPO.

    LED Engineering Research Institute (GLII) statistics show that 2011 domestic production value amounting to billions of LED display enterprises over 40, while most of the LED display enterprises in overseas markets.

    Because the industry is becoming increasingly incentive, over the past few years, some companies started to price low. Especially in the last two years, the price war is not uncommon in the LED display industry. During the display industry average gross profit plunged 20%, business survival increasingly difficult. According to GLII survey data show that the domestic low-end indoor display gross margin of about 15%, 5% -8% of the net profit; outdoor LED display gross margin of around 20%, net profit of 6% -9%. Among them, the LED display in the 2011 industry average price fell 20 percent.

    Has also been reflected in the Absen the prospectus. Of Absen the main business – Full Color LED Display, 2009-2011 annual per square meter average selling price of 12,400 yuan, 12,000 yuan and 10,700 yuan, in 2011 the average selling price dropped by 13.71% compared to 2009.

    It is understood that the LED display enterprises to maintain the normal operation needs to be done at least 30% of gross profit. Hill Wood chairman Shiguo Sheng told reporters that the profits of the domestic LED display in recent years has bottomed out, not much room for future growth.

    With decreasing costs, gross profit has bottomed out, the LED display space is limited, many enterprises are forced to transition. More short-term behavior of the domestic LED display enterprises, to switch the lighting, is quite upset.

    According to Hill Wood, general manager of Shi Guoguang underlying the transformation has a lot of unknown hidden rules. He said that the domestic LED display industry, there is an open secret, that is, the turnover of the enterprise LED display 2-3 billion, will not want to do great. Because bigger means that companies must be to reduce the margin for the price.

    LED display enterprises have been listed on several 2010 annual output and raise investment projects to expand production capacity data show that, where Chau Ming science and technology and the the Liard expected capacity nearly doubled. Production capacity, in addition to Chau Ming technology, the remaining three display companies raise investment projects reached a total of 7 to 8 million square meters. This is also from another point of view, domestic LED display industry concentration is not high, the market share of more scattered, and new competitors to the continuous influx of market competition pattern of homogenization.

  Meanwhile, with the international LED industry shifting to China, overseas competitors to set up production bases in China, China\\ s LED full color display competition in the industry showed a tendency of increase.

    As one of the global LED display giant Barco, director of marketing, Zhaohui Tang, told reporters that China is Pakistan\\ s most important strategic market. Barco in China R & D, manufacturing, sales system. Barco R & D base as well as manufacturing facilities in Changping District of Beijing.

    Core technology, the main advantage is not obvious

    The Absen prospectus, the main products of the company\\ s current high-end LED full color display, divided into more than 30 models of P4, P5, P6, P10, of P16, P20, p21, P25, etc. in accordance with the pixel pitch.

    The company\\ s core technology – outdoor display 3D space with optical technology, LED display electromagnetic compatibility (EMC) technology, low-cost energy-saving technology of LED display, outdoor LED display low-cost reliability in the industry is very popular, so competitive not outstanding.

    At the same time, the company\\ s raised 260 million yuan of funds for LED lighting is about $ 60 million, accounting for 22%. In the field of LED lighting technology in Absen only stay in the second optical design, thermal, drive power testing.

    30 technology patents granted from the prospectus shows the company point of view, of which five of the previous application in 2008, 25 applications in 2011, the 2009-2010 two-year patent is blank.

    In addition, 30 patents, only six are related to the display most of the rest of the LED lighting-related patents, including the bulb lights, spotlights, downlights, panel lights, lamps, etc., reflecting the 2009 to 2011 display, the company and not too many R & D results.

    More importantly, these 30 patents, all of the utility model and design patents, patents for inventions. This is also reflected from the other side do not attach importance to the Absen the overall R & D capacity of less than or patent applications. And display the counterparts of the Liard and Chau Ming far, reflects the Absen the R & D capability gap. The prospectus, The Absen right of these risks are also described. The future, with the growing competition in the industry, if companies can not continue to consolidate and expand competitive advantage, you may face the risk of competitors beyond, and thus adversely affect our operating results. \"Zero down\" mode at great risk

    The prospectus shows, the company in July 2010 for a standardized product A1688, A1088 launch the sales policy of \"zero down payment\" on the part of customers, the customer orders without advance payment, the full purchase price or most of the money paid prior to delivery ( not after delivery by installments). Settlement patterns and general sales, the sales policy of \"zero down payment will be 30% payment (advance payment) charge time of the original sales contract was signed to receive delay before shipping charge.

    In fact, the the Absen domestic display industry pioneered \"zero down\" mode, once in the industry continued to be suspicious.

    Many people in the industry, frankly, the LED display industry is a mature market is very competitive, zero down payment is just a marketing tool. This model, there are many risks, and more than a year in the industry to be effective is minimal. First of all, zero down payment for some small part of the customer base, not all customers can use this mode; Second, the use of zero-down payment mode must be to raise prices to ensure that the operating costs. Therefore, not only require customers need to have a good reputation, but also to have a strong financial strength and support of

    This reporter has learned, the domestic model for zero down payment are generally government projects in foreign countries are generally large companies and consortiums. But no matter what, this model of customer research capacity poses a challenge.

    Not only the challenges of research strength, zero down payment mode on product quality also put forward higher requirements. \"If the quality is not good, then the business must pay for the display, to pay the next within a certain period, if the quality is bad, the client can always terminate the payments.\" Industry sources, zero down payment is the product quality .

    At the same time, the risks of zero down payment is also reflected in the \"tailored\". LED display of a terminal project are tailored to the customer control of the initiative, upon return, then display enterprises are tailor-made for the piece of screen to pay the other hand, display the enterprises difficult to find the same requirements of customers in a short time.

    Therefore, the \"zero down payment, there is a huge accounts receivable and inventory risk. Earlier, the the Absen marketing vice president Ren Yonghong said in an interview with reporters: \"zero down payment has also increased our company\\ s internal challenges to speed up shipments and production cycle, this is a major challenge in terms of our internal management.\"

    The prospectus shows that the 2009-2011 The Absen stock of 33,106,300 yuan, 46,706,200 yuan, 60,429,400 yuan. The data show that the 2011 inventory as compared to 2010 increased by 29.4%.

    Investment banking, according to a broker who said: \"zero down payment mode because the display gross profit to raise so many ready to display the impact of an IPO companies tend to bite the bullet and risk to do.\"

    Involved in lighting, the future does not deterministic large

    The prospectus shows that the company will seize the opportunity of rapid development in the field of LED lighting, the lighting business to become a new profit growth point. Also pointed out that in the sales model, the overseas sales of LED lighting products will use the company LED display customer channels, promotion and sales.

    The last two years, whether it is traditional lighting, LED lighting companies are stepping up the channel agents penetration and control.

    In fact, the channels with the lighting of the LED display channels is a big gap. The Absen original customers are advertisers, radio and television systems, stadiums, theaters, etc.. LED lighting of the proxy object is the government, designers, lighting agents, and ordinary consumers. LED display manufacturers be able to make the original agent to accept a completely unfamiliar territory. \"A lot of people in the industry expressed concern.

    LED display enterprises can supplement existing channels to strengthen and expand the LED lighting, sharp extension display Chairman Dan Yaozhong said: \"LED display enterprises in the lighting field, the formation of core competitiveness and advantages will be more difficult.\"

    In addition, the main overseas markets Absen, also facing strong competitive pressures of the overseas LED lighting giant. These enterprises are controlled almost most of the core technology of LED lighting, and use its patents to suppress and restrict other LED lighting companies in the overseas market expansion. Clearly, whether the Absen LED lighting business can copy the glory of the original display business in overseas markets is still an open question.

    The Absen insiders, the company is to NVC OEM. For Absen just entering the field of LED lighting, if the company in quality control, delivery time can not continue to meet customer demand, the company\\ s major customers may shift to the procurement of other manufacturers will be the company\\ s business adversely affected.

Earthquakes and other natural disasters, emergency lighting, escape, disaster relief and other necessary equipment, however, the emergency lighting often has a defect, the illumination time is short, generally only one hour. Ningbo National Hi-tech Zone, a national high-tech enterprises has recently developed the first not only to achieve the energy efficiency requirements in everyday use, but also in the event of an emergency power failure to provide adequate illumination and lighting time for escape, the rescue of property and power system emergency repair efficient LED lamps. Not long ago, the topic of indoor LED emergency lighting application integration technology development and demonstration "national" 863 Program "3.15 million yuan of special funds.

According to reports, the earthquake emergency, power outage, in the past for emergency fluorescent lamps, this lamp, despite the greatly reduced compared to the incandescent lamp power consumption, but to rely on batteries as the only electricity , he was able to maintain the current work only one hour. The use of LED lighting as an emergency use, and its work at least 3 hours or more, the big reason for the increase of the power supply time is energy-saving LED lights.

L spectrum samples Opto Semiconductors GmbH in Ningbo National Hi-tech Zone, showrooms, staff reporter did an experiment. A board, installed incandescent, fluorescent energy-saving lamps and LED lamps, power incandescent lamp luminous flux (ie light intensity) from 200lm to fluorescent lamps of luminous flux of 220lm LED lights for 260lm, but incandescent power of 25W, the power of fluorescent lamps 5W LED lamp power is only 3W, indicating that the light emitted by the LED light is the brightest, but the energy consumption is the lowest.

General manager Zhang daylight, said, in working condition, the LED lights than incandescent 80% energy savings than fluorescent energy saving lamp energy saving of 30% to 60%. Therefore, the LED lights apply to emergency lighting when it s working time is greatly extended.

The reporter learned that the the Cuiwei Tokyo, Japan, commercial buildings using the l spectrum of optoelectronic LED emergency fluorescent. In the snow disaster in Wenchuan earthquake a few years ago by their R & D production of the portable LED emergency lights, played no small role in the relief of lighting. Portable LED emergency lights with manual power generation, and very easy to use, hand shake the handle of one minutes, you can use lighting 15 minutes.

Zhang daylight admitted that the LED light is less than 10% market share, its high price is the impact it went into the homes of ordinary people "stumbling block", the rare family will use the expensive LED lights, at the same performance the price of LED lights three times to six times the ordinary energy-saving lamps. However, Lin Sheng said, LED lights on the energy saving advantages, in the next 3-5 years, its sales will enter a stage of development. "After all, the life of the LED lamps can reach 30,000 hours, in addition to the manufacturing process of the environmental protection, energy saving and environmental protection in the course of more clearly reflected." Zhang daylight calculations to reporters: LED fluorescent industry goal of 1 million per month calculation, the annual reduction in electricity consumption for the country 2.1 billion kwh, saving 8.4 million tons of water, saving 840,000 tons of coal to reduce the 570,000 tons of toner dust emissions, reducing carbon dioxide emissions of 2.1 million tons.

1, control valve selection:

Currently, the project commonly used control valve: solenoid valves and electric valves. However, in use, they have shortcomings, such as solenoid valve susceptible to blockage, water resistance to be the maintenance of long-term hand; electric valve, no water resistance, but because of the need to have the necessary control circuit, so the water vapor erosion life is also troubled by the promotion of the main problems.

2, how to maximize overcome the scale of the valve used

Solenoid valve or electric valve, the scale will not only cause the valve to leak, even when serious will affect the normal operation of the valve, how to eliminate the influence of the scale is the industry issues of common concern.

The process of the control valve to the scope is too broad, not them here to give you clear, I hope the content of this field also personally go to find information. However, due to the design implementation of agencies and the use of different filling materials caused by the control valve performance difference can be summed up its own rules: the process dead zone exists will make the process variables to deviate from the original set point. The output of the controller must increase enough to overcome the dead zone, the only corrective action will occur. 2, ① The main factors affect dead zone. Friction, wavering, the valve shaft to reverse the amplifier of the dead zone. Variety of control valves is not the same on the friction-sensitive, such as the rotary valve for the friction caused by the high seat load is very sensitive, so use notice this. But for some of the sealed type, high seat load is necessary to obtain the closing level. Ha ha, so that this valve designed is very poor, likely to cause a lot of dead zone, the impact of process variation is obvious, was decisive. The ② wear. Valve during normal use wear and tear is inevitable, but the wear of the lubricating layer is the most powerful, according to our experiments confirmed that lubricate rotary valve after only a few hundred cycles the action, the lubrication layer is almost ready to just brush (exaggerated , or write articles very depressed). Addition, the pressure load can lead to wear of the sealing layer, have all contributed to the increased friction of the main factors. The result? Is to control the performance of the valve caused devastating ③, packing friction, is the main source of control valve friction, the use of different fillers, the friction is very different. ④, the type of the implementing agencies of friction have a fundamental impact, in general, spring diaphragm actuator piston actuator.

3, positioning of the design issues.

The sake of the initial thinking of the design, executive agencies and locator design must be considered together. How to design a good locator? Know that from his important features must be a high-gain devices. The gain is composed of two parts: the static gain and dynamic gain. Improving the static gain is to design a preamplifier. Such as nozzle – baffle device. Then have a friend to ask the dynamic gain how? Through a power amplifier, power amplifier is the slide valve (General). Now, some people have used the microprocessor to set the locator. Evidently valve will speak later told we where bad. Then Hou do maintenance simple. Returning to the subject. Has both high static and dynamic gain of the high-performance positioning can reduce process variation in terms of best overall performance for any given valve assembly.

The prospectus shows that the company will seize the opportunity of rapid development in the field of LED lighting, the lighting business to become a new profit growth point. Also pointed out that in the sales model, the overseas sales of LED lighting products will use the company LED display customer channels, promotion and sales.

The last two years, whether it is traditional lighting, LED lighting companies are stepping up the channel agents penetration and control.

In fact, the channels with the lighting of the LED display channels is a big gap. The Absen original customers are advertisers, radio and television systems, stadiums, theaters, etc.. LED lighting of the proxy object is the government, designers, lighting agents, and ordinary consumers. LED display manufacturers be able to make the original agent to accept a completely unfamiliar territory. \"A lot of people in the industry expressed concern.

LED display enterprises can supplement existing channels to strengthen and expand the LED lighting, sharp extension display Chairman Dan Yaozhong said: \"LED display enterprises in the lighting field, the formation of core competitiveness and advantages will be more difficult.\"

In addition, the main overseas markets Absen, also facing strong competitive pressures of the overseas LED lighting giant. These enterprises are controlled almost most of the core technology of LED lighting, and use its patents to suppress and restrict other LED lighting companies in the overseas market expansion. Clearly, whether the Absen LED lighting business can copy the glory of the original display business in overseas markets is still an open question.

The Absen insiders, the company is to NVC OEM. For Absen just entering the field of LED lighting, if the company in quality control, delivery time can not continue to meet customer demand, the company\\ s major customers may shift to the procurement of other manufacturers will be the company\\ s business adversely affected.
