Lunda electronic Su, chairman and general manager, said low-cost direct type LED TV optimistic outlook, Lunda Electronics corresponding high power LED is already in place.
This year’s Taipei International Optoelectronics Week, the Lunda electronic Su, chairman and general manager of foreign first relenting, low-cost direct type LED TV will inject Lunda Electronics third quarter revenue contribution, while LED lighting demand is still strong, and will revenue growth for the company another big momentum; LED lighting this year, the focus remains under industry, many manufacturers are competing to display LED plant lighting, a new bright spot in the show, visible LED lighting has been in different application areas flourish . Obviously 2012 LED TV and LED lighting output growth will be driven by two strong road, become the LED supply chain vendors focused product line deployment, to carve up market opportunities pie.
cheap direct type LED TV incentive Ronda Q3 orders increase in volume
Lunda Electronics Q3 1 watt LED shipments will be significantly higher. Benefiting from low-cost direct type LED TV brands intensify expand product lines deployed, Lunda electronic orders for the second half of the high-power LED has been significantly improved; Once the terminal market to buy gas heating, will be able to inject a lot of revenue contribution.
Su, said third quarter the traditional peak season for television, targeting low-cost direct type LED TV irresistible, many TV brands planned for the second half of aggravating cheap direct type LED TV product line layout, is expected to improve Lunda electronic procurement proportion of high-power LED.
Currently Lunda electronic high-power LED is small shipments to mainland China and other countries of cheap direct type LED TV customers, representing high-power LED products Lunda ratio is still low. Su, that TV brands to increase low-cost direct type LED TV product shipments later, still depending on the initial actual market sales in order to determine the number of additional purchases, so the second half Lunda used cheap electronics direct type LED TV’s high-power LED is still hard to determine the final shipments.
However, due to low-cost direct type LED TV The use of high-power LED, using the number of pieces will be greatly reduced, fear will impact the overall revenue. In this regard, Su Feng positive response, unlike the edge-lit LED TV uses low power LED number and the structure more simple, direct type LED TV uses less high-power LED number, then to add the second optical lens , the design is relatively complex, so price is higher than the low power LED about 10%; although direct type LED TV uses LED number decreased, but the overall revenue has not been much affected. Su Feng is expected in 2012 Lunda Electronics LED TV product line with all lighting applications will show growth momentum, which edge-lit LED TV’s growing strength is still strong, is still the main market; For cheap direct type LED TV this year, driven by revenue amount, still depends on the second half of the market to buy gas. Worship LED TV and lighting market expansion, thanks to Lunda Electronics capacity utilization also continued to rise. Su, revealed that, at this stage Lunda Electronics capacity utilization rate has reached 80%, the third quarter is expected to point to 90%. 2012 Lunda electronic LED lighting revenues will grow substantially, however, Su, stressed that the LED unit price continued to fall, so although the LED lighting turnover will significantly increase the proportion of revenue contribution will remain at last year’s 3,040 percent.
LED lighting market to benefit from this expansion, Ronda LED chip production capacity utilization rate optimism, Su, said, Lunda electronic LED chip capacity is tight, has gradually replaced and added capacity five times higher than the 2-inch 4 inch metal organic chemical vapor deposition (MOCVD) machine, overweight continue to expand production capacity, the future will represent Lunda Electronics proportion of the overall number of machines more than 50%, the current total number of Lunda electronic MOCVD machine nearly 80 units.
However, Su Feng is that, in the absence and North America, the European debt crisis, LED lighting market in Europe and North America will grow faster. 2012 LED lighting market is still the largest in Japan, accounting for about one-third; followed by Europe, accounting for 2030%; Furthermore is the Asia-Pacific region, up 20%;, and North America about 10%.
In addition, Su, further analysis, despite the 2012 LED lighting costs dropped sharply, but to allow the rapid popularization of LED lighting is not easy, largely based LED lamps made of metal, glass and take the appearance of traditional bulbs feel very different, the end consumer required more time to adapt to new products, coupled with Europe and the United States economy turned sluggish, leading builders cover reduced the proportion of new building, the terminal proportion of consumers to buy second-hand housing rose, as compared to the new building, old house with LED lighting proportion is not high, it is affecting the LED lighting market share.
In addition to the commercial, construction and home lighting market, green technology for the LED lighting industry, agriculture is expected to inject another unit running water.
<strong> rise of green technology LED plant lighting business of agriculture to take off </ strong>
In response to climate change, food shortage and environmental pollution problems, into LED lighting plant factory is booming, the future include building rooftop, home interior with conventional greenhouse farms and other locations are expected to see the various LED plant lighting applications, also will drive the LED lighting device shipments to climb.
Light Yin Biotech CEO Chen Jizong said, LED plant factory is Taiwan to show the world the importance of developing the competitiveness and future urban grain and vegetables are the main sources of supply.
Light Yin Biotech CEO Chen Jizong that dramatic changes in the global climate has led to many parts of the lack of sunshine, high intensity rainfall and other extreme phenomena, directly affecting crop productivity and quality, resulting in worsening of agricultural economic losses. Therefore, with effect from the weather and plant production capacity of the plant has begun to stabilize by the industry concerned.
Chen Jizong further pointed out that due to the indoor environment plant factory and LED lighting equipment import substitution generally sunshine, so you can control the plant growth environment. The LED lighting can also be due to different plant species, further adjustments to the most appropriate for the crop growth light environment; generally the most common practice is to adjust the LED lighting in the red and blue wavelengths, and even fine-tune the green light can be added in order to enhance crop growth environment quality.
In fact, according to use light plant factory is divided into three categories, one for sun-using, that is conventional precision greenhouse; second is sunlight and artificial light and use type is defined in the sunlight outside, also uses artificial light strengthened; third is completely artificial light type, early is to import high-pressure sodium, but prone to overheating, making the type of plant factory cooling costs higher, now benefit from the LED lighting technology matures, the heat issue has been solved.
LED plant lighting equipment generally required to have a larger spectral range and combination of multiple light sources to be able to meet the plant factory for LED lighting requirements. In addition, the plant factory to enhance the quality of crop growth for LED plant lighting source efficiency, irradiation distance is also required, and Taiwan LED manufacturers technology and capacity are among the best in the world, will be cut into the largest application market for this one weapon.
It is understood that, at present, including the new century, Everlight, wang energy and other industries who spotted the plant factory will gradually prevailed opportunities have switched heavily invested LED plant lighting market. Future costs continue to decline with the LED, LED lighting is bound to become a quality agriculture and greenhouse agriculture standard with higher economic benefits for farmers and less risky production advantages, thereby stimulating the development of LED lighting industry.
Another concern is that, LED TV and lighting costs plunged from the main cause of the rapid decline in the price of the sapphire substrate and the silicon substrate GaN (GaN-on-Si) is difficult to improve yield under the influence nitrided silicon substrate Gallium cost competitiveness, it is difficult and expanding LED market territory.
<strong> yield breakthrough silicon nitride aspiring to be difficult stretch </ strong>
Since the fourth quarter of 2011, a sapphire base wall quote below $ 10, although rush orders poured LED TV lift, the sapphire substrate hardly returned more than $ 10 price level, fear will make silicon nitride LED lighting Market fist difficult stretch.
Dow LED technology marketing director Nathaniel E. Brese that optimistic LED sapphire substrate to grow annually to maintain two digital trend, Dow will actively enter this market.
Dow Chemical (Dow Chemical) LED technology marketing director Nathaniel E. Brese said that at this stage confined to the silicon substrate GaN yield, cost and performance is still hard to keep pace with the sapphire substrate, so sapphire substrate systems can maintain an annual growth rate of 20% , the estimated short-term three years, the sapphire substrate is still hard to shake the mainstream market position, as a long-term perspective, the silicon substrate GaN and sapphire substrate in the mountains in the LED lighting market.
Currently TSMC, Osram Opto Semiconductors (OSRAM Opto Semiconductors), Puri (Bridgelux) and other manufacturers have gradually expanded silicon substrate GaN deployment, which will jointly Puri Toshiba (Toshiba) jointly developed 8-inch silicon substrate GaN LED , is scheduled to be introduced mass production in early 2013.
Brese that in the past the high price of the sapphire substrate, so that the industry hope after the advent of the silicon substrate GaN have the opportunity to cut the cost of LED lighting, incentive rapidly expanding market penetration, but the observation of both vendors into the silicon substrate GaN R & D schedule, which shows the current yield is still quite low, if not break, the fear will impede penetration stumbling block.
As silicon substrate GaN yield, Brese pointed out that due to the company is not publicly precise information, it is not yet released accurate reference number.
Brese mentioned that nowadays most developing silicon substrate GaN and sapphire substrate manufacturers are Dow Chemical’s customer base, in view of the silicon substrate GaN market prospects can be expected, it is expected there will be more new entrants to join market fray, while speeding up the silicon substrate GaN LED commercialization schedule.
Currently Dow silicon substrate for GaN and sapphire substrate manufacturers, has launched optical lithography (Lithoraphy), chemical mechanical polishing (CMP), and is widely used in MOCVD machine epitaxial growth technology leading products such as materials and mix, ready to grab market aggressively.
Thus the above, the second half of promising low-cost direct type LED TV and lighting under considerable opportunities, LED supply chain vendors have been actively card, flags market territory. “

LED downlights and other related industry is in a stage of rapid development. We are pleased to scientific and technological progress, although the development of LED, but only a few decades, but now it has created a new lighting situation. Advantage to play with the LED, LED lighting will eventually change the traditional lighting present structure and layout of the core technology and value chain will change a lot. Currently, Grow Plant Lamp LED lighting products, compared with the ordinary, the biggest obstacle is the price, but the decline in prices of LED lighting products is an inevitable trend, in addition to the falling cost chips, companies should also consider aspects from the driver to control the LED costs. The modular LED development is to reduce the cost of production is one important way. LED modular concept is not new, but recently the trend seems increasingly obvious, as the core components, such as LED substrate, epitaxial process technology such as costs decline, including the driver control the proportion of share of the cost will be more higher and higher, how to systematically reduce lighting costs is very important, traditional LED lighting industry chain, tend to focus on epitaxial materials and chip manufacturing parts, but the development of semiconductor lighting industry today, cost reduction and efficiency improvement two driving forces will make the whole industry value chain are increasingly reflected. Should be integrated to form epitaxial chip, package integrated modules or light engine and other such upstream suppliers, then the light source and the lamp assembly (simple) in the low end of the value chain, lighting design, and intelligent lighting brands value will be highlighted. Many LED lighting companies have associated modular products, and achieve different LED module interchangeability of products, versatility has also been a topic of great concern to the industry, along with the trend of LED modules is becoming increasingly apparent, the end of the LED module products, “Warring States” conditions, to achieve standardization of LED module industry as a whole has become more urgent and more control of the market to become an important manifestation of the right to speak.
LED downlight energy-efficient lighting in recent years to become the new darling of the market is playing an increasingly important role, but also set off an unprecedented boom. In order to reduce energy consumption, in response to the call of the national energy saving, but also to protect the environment, various places in the city most of them use the energy-saving lamps, energy saving lamps in, LED downlights and its occupation lasting durability the lion’s share of the market. LED downlight high stability, not damaged, millions of continuous switching operation will not damage the light source, while the number of energy-saving lamps and only about 5,000 times. Meanwhile, Grow Plant Lamp LED downlight light angle, high luminous efficiency, brightness uniformity, less power consumption, long life of 50,000 hours, is 10 times more energy-saving lamps. In the same brightness, LED downlight energy saving than fluorescent lamp 20% energy saving than incandescent more than 120%. (Green Feng Electronics: LED Downlight, clean energy truly green lighting
The European Commission said in a press release, LED panel lights and other lighting is one of the most energy-saving lighting, “Grow Plant Lamp” lighting technology 70% energy saving than the traditional. The popularity of LED products can promote the development of lighting industry, and by 2020 the lighting energy consumption at current levels on the reduction of 20%. It is because of the LED lighting industry abroad than in domestic is more developed, and the recognition degree is higher, so many domestic LED lighting enterprises to settle on this business, pay attention to the export business, this and the proportion with LED lighting products certification continuous growth. For example, CCC certification LED lamp, LED lamp; the CQC certification LED module for electronic control device, LED lights, LED tunnel lights, general lighting self-ballasted LED lamps, the energy-saving certification of enterprise applications is also very enthusiastic. In the CCC certification and CQC certification process, small business products appear many problems in the certification process, often require repeated rectification, mainly concentrated in the structure, the external conductor, waterproof and dustproof and EMC; there are nearly 20 enterprises to obtain certification for energy-saving LED lighting products, of which more than 90% are still large traditional lighting production enterprises, these enterprises with good lighting products research and development foundation, which provide convenient conditions for the development of LED lighting products; many enterprises often pass. From the enterprise of geographical distribution, the Yangtze River Delta, the Pearl River Delta, Fujian, LED lighting products production base. In recent years some inland regions will also LED lighting as an emerging industry, but because of the lack of talent and technology, has not yet formed climate. LED road lamp production enterprises, certification number; because the LED road lighting lamp is the most complex structure, certification by the lowest rate. Product certification is the foundation for the promotion of LED, a basic guarantee is the standard LED lighting products and market.
At present, the global energy consumption grow with each passing day, single is lighting accounted for 20% of global annual total electricity consumption of high.”DECORATIVE LIGHTS” Therefore, in the idea of low carbon life more win support among the people on the occasion, the emerging LED lighting industry with green lighting as the core is fast becoming the concern of the industry and technology. LED lighting in the future development trend is toward intelligent direction, elements of intelligent working environment should be included in the “simple, flexible, comfortable”, it can make the office more comfortable, more effectively improve work efficiency. Office lighting is a major energy consumer in the city. The large number of office buildings, due to the high energy consumption of the lighting system, the city a lot of energy consumption, emissions of carbon dioxide, causes a great burden to the environment in the city. Intelligent LED control system applied to office buildings and high-rise building staircases and aisle lighting, will be able to give full play to achieve energy-saving advantages of LED, according to need “lighting” concept, to “people to light, people walk dimmer lights”, achieve good energy saving effect. The main developing trend of office lighting lamps are: energy-saving, functional diversification, including high color rendering, intelligent, flexible, lightweight and environmental protection, he said, LED lighting has many advantages of application in the office, the LED plane lamp is a new generation of office lighting products fully comply with the market demand. LED flat lighting is generally used for commercial, office, business and other places, high brightness, uniform light, beautiful, energy-saving and environmental protection. Specifically, LED lamps compared with traditional lamps, spot uniformity without dark area of soft light, no glare, can be used as the preferred lamp large area lighting area; light weight, uniform heat distribution, good heat dissipation effect, product life more easily guaranteed; and the auxiliary lighting lamp used in conjunction, can reach good light levels. Effect of. According to the industry is expected, with the decline of technology and cost, LED lighting a lot to replace incandescent and fluorescent lamps will start in 2012, and reached a peak in 2020.
As an alternative to traditional lighting, very broad prospects for the development of high-power LED Downlight.”LED NET LIGHTING” Development, production, marketing and use of high-energy, long-life, high luminous efficiency, excellent color advantage of LED lamps, lighting manufacturers the most important concern. The emergence of high-power LED downlight replaced since Edison invented the light bulb, the form of traditional light sources used since the filament light burning. It has no filament to burn, coupled with high-frequency coupling, all of its energy is converted to light energy, solve the – totally dependent on the filament of the lamp is lit burning, not only the filament life is limited, and most of the energy is converted to heat, both consume a lot of energy and pollute the environment, troubled by the problem of the lighting industry in the last hundred years. The superior characteristics of high power LED downlights energy saving over 5 times, long life 5 times, three times lower in temperature, plays a vital role in saving power resources, reducing the greenhouse effect. High power LED downlight set as an energy-saving, environmental protection, health, long life, stable performance, is a revolution in lighting field, is a veritable “fourth-generation light source is bound to the current light source is bound to replace the goods. With the global energy crisis worsened, the aggravation of a waste of resources, pollution, ecological damage, the survival of mankind has faced serious challenges, advocated the building of the “energy-saving society” has been recognized by the majority of countries around the world, “energy saving, emission reduction “as a national policy of countries in the world. High Power LED Downlight the vanguard of the light source as energy saving and environmental protection, and its prospects will be unlimited, also dealers golden opportunities lie. The the incomparably superior performance of high-power LED Downlight decision it was adapted to a very wide range, high power LED downlights can be applied in the field of: solar road lighting, courtyard, plazas, factories, mines, tunnels, ports, shipbuilding and other lighting.
