LED lighting: a light to change the world

  Hot summer is approaching, and a peak is approaching, energy naturally become not open around the topic. How families saving it? Choose energy-efficient lighting products is clearly an important tool.  Do not underestimate this little lamp energy saving lamps. Data show that, at present, China accounts for about 13% of lighting electricity consumption of the whole society, if at all incandescent replaced with energy efficient lighting products, the annual saving 48 billion kwh. If the whole society led strips products to replace, the annual saving of about 350 billion kwh, equivalent to four generating capacity of the Three Gorges Hydropower Station.  Mr. Shen, who lives in Zaozhuang City, Shandong Province, recently renovated house, he would have been replaced with the house lights energy-saving lamps. Compared to incandescent lamps, energy-saving lamps are currently expensive, however, Mr. Shen heart has a pair of "small thinking", "incandescent is cheap, but easily broken, energy-saving lamps worry, a few years to recover the cost."  Mr. Shen facts really envisioned it?  We have to count an account: Tests showed that a 5W 25W energy-saving lamps and incandescent light has the same effect, and also about 8 times its ordinary incandescent lamp life. Just from the price point of view, to buy a high-quality energy-saving lamps is about 10-15 yuan, equivalent to spending 5-8 incandescent price. However, energy-saving lighting life of 8,000 hours, the equivalent of eight incandescent sum. On power consumption, 25W incandescent 40 hours will consume 1 kwh electricity, if used to replace energy-saving lamps 5W, 40 hours consumes only 0.2 kwh electricity. Long-term use, or more cost-effective energy-saving lamps, and better lighting effects.  From 2009 to 2013, the National Development and Reform Commission has launched a green lighting project office in 27 Western Region saving lamps donation campaigns to promote energy-saving lamps donated a total 2.587 million, the estimated annual saving of 120 million kwh, electricity savings 060 million yuan.  This is just a microcosm of China in recent years to promote efficient lighting products. According to statistics, from 2008 to 2010, the central government invested a total of 2.562 billion yuan, promote efficient lighting products 360 million. "These were generated electricity efficient lighting products in the life cycle of about 66 billion kwh." China Lighting Association, said Liu Sheng-ping, by 0.5 yuan / kWh tariff calculation, one yuan of central government subsidies can save 13 dollars , or a total for the majority of urban and rural residents and users of bulk energy-saving lamps save about 33.3 billion yuan in electricity costs.  Not only that, driven by financial subsidies to promote policies, lighting products industry is becoming standardized. "There is good quality, affordable green led strip light products gradually become the mainstream lighting market, counterfeit products are further squeezed the living space, but in smaller cities and rural areas, promotion of green lighting products is still the weak link." National Development and Reform Commission Lu Fang, deputy director of the project Management Office to promote energy-saving lamps frankly.  As the field of lighting savings Star, energy-saving lamps are accompanied by the evolution of the performance of stabilization, lower prices and technology, as well as changes in consumer spending and gradually become the mainstream concept of choice in our lives lighting. Recently, the emerging LED lights become more significant because of its energy-saving effect and easy to control, even a "Star of Stars."  Shanghai Yaming Lighting Co., Ltd. Chairman LI Zhijun to reporters cited an example. Benjamin LEDT8 been successfully applied to a number of large supermarket Carrefour in China, the system power is used to replace the original 40W traditional T8 lamps, each store uses about 3800. "In commercial electricity tariff 1 yuan per kilowatt-hour, 18 hours a day lighting calculations, the annual electricity savings per store about 54 million yuan, a year and a half to recover the investment."  Why LED lamp energy saving effect is so superior? This is because only 10% of the ordinary incandescent work when consumed electrical energy into light, and LED lights are energy efficiency can reach 90%. Therefore, a 3W and 5W LED lamp energy saving lamp, 25W incandescent light has the same effect. In addition, LED lamp life of up to 30,000 hours on average, more than 25 times incandescent.  Attention is needed, green lighting products, though "looks beautiful", but the market is still mixed in a lot of inferior products. Some low-quality lighting products, using two or three months after the obvious bad light will appear, and some products have noticeable flicker will cause damage to the eyes. Quality supervision departments suggested that in the purchase of energy-saving lighting products, be sure to choose the regular manufacturers of products, and look for the product certification logo.  "Changing a led strips bulb, and change our way of thinking, we can change the world." UN Secretary-General Ban Ki-moon said. A lamp may be insignificant, but the energy come together so that we can not be ignored. Frugal and Germany to support low-carbon life, might as well start now, start it from each one of us.

LED lights effective way of four lightning protection

Streetlights were struck by lightning when such things happen, as the design and construction personnel, how to prevent the occurrence of lightning it? Streetlights are several ways to prevent damage by lightning the most effective way:  1. Lightning protection zone set up  led strip light in addition to the current power supplies, but also to set some communications equipment used to control the lights off and brightness, and power of these devices are to be resettled in the lightning protection zones, protected areas directly affected by Shell Shield. Electromagnetic field here is much weaker.  2. Lightning equipotential bonding  To completely eliminate the destructive potential difference caused by lightning, power lines, signal lines, metal pipes, so use overvoltage protection equipotential bonding at the interface of each inner protection zone must also be local equipotential connection, various local equipotential connection to connect to each other, and finally connected with the main equipotential place.  3. External and internal lightning protection lightning combine  Now the general exterior led strip light are the conductor material itself is the equivalent of a lightning rod, the design must be installed deflectors and ground network, these systems constitute the external lightning protection system. The system can be avoided due to direct lightning caused fires LED lights and personal security incidents. Internal lightning protection system is a street light inside through the ground, set the voltage to protect other ways to protect the equipment. The system prevents lightning and other forms of over-voltage invasion, causing the power to destroy, it is an external lightning protection system can not be guaranteed. Between these two are complementary and mutually reinforcing. Internal lightning protection system on many devices such as housing, cable and out of protected areas, metal pipes, etc. must be connected to an external lightning protection system or set overvoltage protection, and equipotential connection.

Smart lighting or a breakthrough LED industry development

 With the multi-regional moratorium incandescent, LED lighting costs drop, LED lighting market ushered in a full-blown situation in 2014, especially in the repeated stimulation of things, industry professionals are optimistic about the future of intelligent lighting market space , is expected to become the industry breakthrough. Market analysts pointed out that the wisdom of lighting related stocks performance over a period of time there is no lack of "bull stock" worthy of attention. While the wisdom of lighting the course of development in China over 10 years, but has not been large-scale application, the current application of intelligent lighting is mainly concentrated in the high-end business hotel, exhibition venues, municipal engineering and other fields. Especially in Shanghai. Shanghai many lighting and road lighting are used in the specification and demonstration of intelligent lighting control. However, there are still many smart lighting problems, merely the absence of clear criteria on technical price, service, or application there is a certain degree. LED lighting has been flying into the homes of ordinary people, LED lighting products is to replace the pinnacle? LED in the future will certainly be phased out most of the incandescent lamp. On medical lighting, has developed LED shadowless, also got medical production license. In many places, LED can replace incandescent lamps, but not all. And we need not all. We just want to play to our strengths, we are able to do some good and needs to be done. In 2013 the company's overall revenue reached 1.02 billion, the proportion of the display and lighting is probably 7:3. To be sure, the future will further increase the proportion of lighting. It is understood that wisdom lighting refers to the use of modern electronic technology, automatic control technology, computer technology and communication networks, and assisted by other means, for the automatic control of electric lighting, illumination light to provide a suitable environment at the same time reducing power consumption and other lighting systems use costs. Experts predict that in the next five years China Intelligent lighting market is expected to reach $ 200 billion.

LED packaging manufacturers a big move into the mainstream without gold package

Recently, there is news that Samsung Electronics TV backlight products will be fully flip package (Flip Chip) devices, this is to some packages still harbored doubts on the flip practitioners an affirmative answer. And China, Tang Guoqing, general manager of Samsung LED is affirmed that "no gold this popular package!"

Other big moves

Tang Guoqing said that from a technical point of view, no gold package is relatively mature. Currently, Samsung LED has seen a huge market prospects this package, and with the mass production of high-power package without gold light source device 3535B (second generation) capabilities.

It is understood that the Samsung LED's "no gold package" Product 3535B already reached 140lm / W (@ 350mA), the company has plans to terminate production of products using gold thread, go all the development of non-gold packaging products.

In addition to the apparent movement of Samsung Electronics, Lunda Electronics Show in Frankfurt this year also exhibited in the "no gold" based on the "no stand" light source device, the so-called "non-packaged" products, the company plans in the second the end of the quarter "no package" products for mass production. The move was also seen as Taiwanese companies are quickly cut into the action without gold wire products.

Compared to Samsung's in full swing, Lunda Electronics said, "no package" white LED technology is still in its infancy, maturity and market acceptance of products and technologies that will take some time to improve, and will not immediately SMD cob have a tremendous impact.

The short term, Lunda electronic addition to actively promote "no package" white LED products and technologies to SMD and COB will remain high degree of market acceptance of products.

However, Lunda Electronics believes that the future after the product and the market is more mature, "no package" products both in the light efficiency or price, are more traditional SMD and COB more competitive. In addition, "no package" products have the same flexibility with SMD Chip playing pieces way, as more vendors put this technology in the future have the opportunity to become a mainstream package.

"It can be seen from the attitude of foreign well-known manufacturers, 'no gold package' Although not yet become mainstream, but already 'among the flowers in a flower', Tang Guoqing said.

Downstream firms benefit

Regardless of whether the living conditions of the majority of the middle reaches of the enterprise will be "no gold" extrusion downstream enterprise applications will undoubtedly become the beneficiaries of this technology.

Previously, TSMC has worked with mainland enterprises Topstar Lighting jointly developed using POD (Phosphor on Die) lighting products packaged devices.

Topstar lighting applications, as part of the enterprise, the actual experience of this technology do? According to the general manager of reporters Topstar LED Division Liaoguo Chun understand that this package does not require the application of the terminal reflow packaging plant also Design can be customized according to customer demand.

Comparative analysis of LED lights with traditional sodium

At present, China is creating a resource-saving society, the "green light" environment-friendly concept has gradually popular. With the advancement of technology, the rapid development of semiconductor materials application technology, landscape lighting small power LED light source has been widely used in high-power LED lights are also more and more aroused concerns. LED light-emitting principle: LED (Light Emitting Diode), light emitting diode, is Ⅲ - Ⅳ compound formed is a solid state semiconductor devices, which can be converted directly into electricity to light. LED's heart is a semiconductor wafer, semiconductor wafer composed of three parts, a part of the P-type semiconductor, the hole in it dominates, the other side is N-type semiconductor. When the current through the wire on the chip, the electrons and holes will be pushed to the quantum well, electron hole recombination, and will be issued in the form of photon energy in the quantum well, which is the principle of LED light. The wavelength of light that is the color of light is determined by the material forming the PN junction decision. High pressure sodium light-emitting principle: HPS is the use of electricity, an arc is generated between the electrodes at both ends of the arc tube, since the high temperature of the arc tube of the sodium mercury evaporated into homogeneous heated sodium vapor and mercury vapor, the electrons emitted by the cathode to the anode during discharge impact atom-containing substances, to obtain energy to produce ionization or excitation, and then return to the ground state from the excited state; or ionized state to the excited state, an infinite loop back to the ground state, at this time, the excess energy is released in the form of optical radiation, they produce light. High-power LED street light is a light emitting diode group achieved through a new way of lighting low voltage dc lighting needs, with high brightness, good color and other characteristics; addition, because the LED lights to low voltage DC input, with the Solar combine to make solar LED lights has become a possibility in the future of road lighting the way. 1, on the energy efficiency analysis, comparison Should follow to achieve the same illuminance (brightness) levels, compare the lighting installed near the power under the premise of lighting quality standards. As the high pressure sodium lamp power (250 ~ 400W) high luminous efficiency, up to 130 ~ 1401m / W, while the low-power lamps (100 ~ 150W) luminous efficiency of about 80 ~ 1001m / W, while the active power LED Streetlights multi 1WLED tube light effects are similar, so should the small high-power lights were on power streetlights for analysis. (1) high-power (≥ 250W) Street Light: High pressure sodium lighting efficiency, consider three factors ballast losses, lighting efficiency and optical channel utilization, etc., if the overall efficiency by 0.55 meter, the effective optical efficiency of about sodium 70 ~ 751m / W; effective luminous efficiency LED lights, in the United States is about 621m / W, the best domestic enterprises has reached 56 ~ 581m / W. Thus, the town Runjing streetlights think for high-power lights, the current energy efficiency of LED sodium than the lower. (2) low power (≤ 150W) streetlights: effective optical efficiency sodium lamp (included in the overall efficiency of 0.55) is about 45 ~ 551m / W, while LED based upon 56 ~ 581m / W total, the ratio of sodium to achieve energy-saving LED 10 % to 20%, up to 30%. From the analysis, it was found to slip small power (≤ 150W) when, LED lights up to 10% to 30% energy saving over sodium lamp, but still not as high-pressure sodium lamps for energy efficiency. Therefore, those general claims than high pressure sodium lamp energy saving LED lights, and even energy savings of 50%, 60% and other statements, apparently suspected of exaggeration and hype. We should adhere to scientific analysis, the principle of seeking truth from facts, or easy to mislead users and the masses. 2, analysis of the light source color lighting effects on road HPS correlated color temperature (Tcp) is about 2100K, is a warm color temperature, color rendering index (Ra) is only 23 to 25, the color is low; while the color temperature LED lights are now used much at 5300K, the color temperature is cold, better The product, which can reach 70 to 80 Ra, the color is good. As a vehicle traveling fast road, main road, partial ** sodium light, to see the road in front of about 90 ~ 160m distance condition, slightly better results than white light, especially on a foggy, dusty air conditions, Sodium more advantages. For sidewalks, pedestrianized street, residential area, such as roads, LED color rendering than sodium, tell people the situation clearer, more advantages. 3, comparative economic analysis High-pressure sodium lamps, each of about 1200 ~ 1500 yuan; present LED lights, according to the power of different sizes, the price difference between the larger, about 4,000 to 8,000 yuan. The present situation is concerned, LED lights clearly too expensive, the price of up to 3 to 5 times the giant. As previously? Less than 150W of LED can save 10% to 30% per year per lamp saving about 50 ~ 150KWh, simply can not spend more than the cost of recovering the share of light. Can only hope that in the coming years, LED development trend of its price will gradually decline, to further improve energy efficiency, and then compare their economic performance. led strips     led tape    flexible led strip

Introduction to the LED with sapphire filament scaffold

Recently, with the European and American market demand for LED candle light, bulb light rapid amplification, the domestic many packaging companies into the field, a booming. As a major component of the filament LED bulbs, at present the choice of materials is very extensive, I only to sapphire filament stents in this area are analyzed. A, the processing technology. Processing technology of basic categories can be divided into two steps: grinding and polishing and cutting Grinding and polishing process steps of: cutting - molding - section - grinding and polishing.The earliest to enter the sapphire filament scaffold with substrate polishing technology research and production of taixing city cheng photoelectric technology co., LTD., the company early use of sapphire edge leather for production, greatly solve the waste where long crystal manufacturers. On cutting process, the current mainstream of cutting process has two forms: laser scribing lobes and diamond wire cutting, these two kinds of processing each have advantages and disadvantages: laser scribing lobes way biggest advantage is high yield, narrow seam, can increase the rate of discharge, the disadvantage is that the edge serrated;Diamond wire cutting edge is smooth, but seam width, discharging rate is low, and no laser scribing uniform width tolerance, and in order to solve the problem of strength, still have to undertake secondary annealing.In the long run, to solve large-scale production, is mainly by laser cutting, laser more mature companies in China are now a suzhou delong laser. Second, sapphire, characteristics of the filament. Filament scaffold with sapphire and sapphire processing after grinding, polishing and cutting, in the process of annealing process, can meet the demand of LED bulb light series of physics, features below: 1, excellent heat transfer performance. Sapphire filament stand high temperature of 2050 °, with excellent heat transfer performance, no matter how internal temperature changes, will not cause deformation and fracture because of the heat bilges cold shrink. 2, improve the brightness. Sapphire filament stents using polishing processing, improve the transmittance, after the examination, transmittance can reach more than 85%, far more than other materials. 3, the intensity is big, small volume. Sapphire in single crystal material hardness is second only to diamond, and greater intensity, 30 (long) (wide) * 0.4 * 0.8 (thick) in mm sapphire filament scaffold compressive load of up to 150 g, very big, improves the yield of the client process, because of greater intensity, so the volume can be made smaller and can even be 30 (long) (wide) * 0.4 * 0.6 (thick) mm, other materials is insurmountable. 4, long lamp life. The main material of the LED chip as the sapphire, if the sapphire filament scaffold, the combination of the two parts better, physical properties, can greatly increase the life of the bulb, according to the theory of short board, if because the life of a filament affect the service life of the bulb, it will cause for 2 yuan bulbs filament stent LED to 25 yuan scrap.The sapphire filament will overcome the short board. Three, sapphire, the prospect of the filament scaffold. At present, used in the sapphire filament scaffold material, the quality of the sapphire material is the most superiority, the core of focus on the price. Sapphire filament after several links of processing, combined with the high cost of materials, relatively more expensive compared with other materials, but we believe that this relatively expensive material will not affect the sapphire in LED filament, the application of specific reasons are as follows: 1, sapphire, filament support the original price of 1.2 yuan/article, with the improvement of the processing technology is now down to 0.6 yuan, down by almost half, this price is completely can meet the expectations of packaging enterprises; 2, especially can't be ignored is the sapphire filament support costs accounted for in the LED bulb light.At present the sapphire filament in the bulb cost of weaker than about 1/2, 1/3, and sapphire filament Support account for less than a third of the cost of the filament, in other words, according to the current price is calculated, even if the sapphire filament scaffold not a penny, the light bulb cost but also decline 2 yuan, therefore, the price of LED bulbs and eventually does not depend on the filament scaffold; 3, sapphire, the price of the material not expected will rise sharply as imagined.Many people think that with sapphire applied in the field of mobile phones, the material price will be high, actually otherwise: first of all, sapphire, light silk is the long sapphire crystal sapphire material used the "from" of the enterprise, this kind of material with the capacity expansion of numerous sapphire manufacturer, the supply will be more and more, even considering the sapphire market turning, also won't lead to the rise of materials;Secondly, numerous influx of sapphire filament manufacturers, will lead to price on small profit margins, as long as the existence of a large number of production enterprises, will not have to worry about the rise in materials. Therefore, we think, in a relatively long period of time, the sapphire material as first choice of filament scaffold, irreplaceable. Fourth, think about the development of the industry. Many of the industry in China are dying on the herd, we worry about now is the herd will enter the sapphire filament stent industry. According to investigation, at present is engaged in production of sapphire filament supports not only the taixing cheng photoelectric, Harbin rhett, wuxi yuan well-known enterprises such as light, and many have cut before, crystal, piezoelectric crystals have flooded in, on the premise of do not have access to customer trust, take the initiative to play up the price war, lead to market confusion.

In fact, a rational packaging companies in choosing suppliers, must consider the two factors are stable ability to process and continuous delivery of the goods, if only because the price of these small plant is to turn to their purchase, will be planted blooper.

Osram 2Q14 Earnings Sees Significant Growth in LED Business

 Osram recorded a significant year-on-year earnings increase in the second quarter of its fiscal year 2014. The business with LED-based products (Solid State Lighting, or SSL) continued to rise strongly in the second quarter and achieved a revenue share of 34 percent. "In the recent quarter, we did well in a challenging environment. In light of the decline of the traditional general illumination business, our revenue target has become more challenging. We are very confident regarding our earnings target”, said Wolfgang Dehen, Chief Executive Officer of OSRAM Licht AG. “To reflect the accelerated transition towards LED technology even more, we will separate the SSL business and the business with traditional products from one another within the reporting segment Lamps & Components. The intention is to sharpen the focus for the different strategies of both businesses and to increase entrepreneurial responsibilities as well as external transparency.” Osram is implementing or planning further measures to improve structures and processes. These include reorganizing the general illumination sales organization as well as setting up a global shared service organization, among other things. Osram reporting segments and regional developments Osram’s opto-semiconductor components reporting segment Opto Semiconductors, or OS, recorded a revenue increase of 14 percent on a comparable basis in the second quarter, with contributions from all regions and businesses. General illumination and industry sales recorded particularly strong growth. At more than 19 percent, the EBITA margin was exceptionally high and included among other things a gain of more than €7 million from an insurance reimbursement. OS will officially open its new LED assembly plant in the Chinese city of Wuxi at the end of May. Specialty Lighting (SP), with its Automotive Lighting and Display/Optics units, also continued to benefit from rising demand for LEDs in the automotive industry. On a comparable basis, the segment’s second-quarter revenues rose eleven percent, with all reporting regions contributing to this development. The automotive business has been growing faster than the global car production for 17 quarters now. Thanks to high capacity utilization, SP again achieved an EBITA margin of about 16 percent. In the Lamps & Components (LC) reporting segment, which covers the product business with lamps, light engines and electronic control gears, the clear decline of the traditional business also impacted the second quarter. Total comparable revenue was down two percent, even though revenue with LED-based products rose 40 percent on that basis. The adjusted EBITA margin fell to slightly above five percent, in part because of the rising revenue share of LED-based products. These are less profitable. As announced during the Osram capital markets day (CMD) at the beginning of April, the businesses of the reporting segment Lamps & Components will be reorganized as of May 1, 2014: The traditional business will be bundled in the business unit Classic Lamps & Ballasts (CLB), while the LED-based businesses will be pooled in the business unit LED Lamps & Systems (LLS). Both business units will also be part of the company’s financial segment reporting from the third quarter. The Luminaires & Solutions (LS) reporting segment comprises luminaires for professional customers, products for consumers, as well as the service and solutions business. In the second quarter, LS recorded a significant sales decline of 19 percent on a comparable basis, mainly due to luminaire portfolio adjustments and the restructuring of the service business in North America. The adjusted EBITA margin was about minus 25 percent. Osram anticipates that the decline in sales has now bottomed out. From a regional perspective, the Osram reporting region APAC recorded a year-on-year comparable sales increase of three percent, while revenues in EMEA rose two percent. In both regions growth was again driven by OS and SP. In the Americas region, revenues on a comparable basis fell slightly by one percent, in part due to the ongoing reorganization of the North American service business.

Taiwanese LED Industry to Benefit from Rising Won

 The Korean won is anticipated to rise against the U.S. dollar in the coming months, the strongest in six years. The Taiwan new dollar, on the other hand, is expected to depreciate against the Korean currency, according to a recent Commercial Times report. Foreign investors believe that the strengthening of the Korean won relative to the Taiwan new dollar will benefit the panel, touch panel, LED, and IC package test service industries in both countries. However, Taiwanese oil and mobile device industries (which rely heavily on imported panel and components from Korea) will suffer as the currency inflates. Although fluctuation in the Korean won is often times similar to the Euro, the reasons behind the recent rise are due to expanding trade with China, said Chief Economy analyst Xie Guozhong, former chief Asian economist at Morgan Stanley. This also differs from previous exchange rate fluctuations in the Japanese yen brought on by monetary policies. It is anticipated that the rise in the Korean won will stop for a while and then start to depreciate.
