The LED lighting market continues to be hot. Currently, the most commonly used chips in the lighting market are low-power chips and modules (3020/3528), as well as high-power chips and modules (1WEmitter). In terms of application interval, due to the advantages of COB polycrystalline package with point-like light source and lm/Area, the Japanese bulb market in 2010 began to be dominated by COB polycrystalline packaging, and traditional high-power chips and modules are mostly used. In the MR16 and other directional LED light sources, however, in the early days of the bulb market, some people used 1W high-power package to design bulbs. As for PLCC, the small power package is mainly used in lamps or grid lamps. Equally optically active products. It is generally believed that LED general lighting will have explosive growth in 2011. In particular, the demand and demand area of ​​LED bulbs will grow rapidly at a double speed. Another application with explosive growth potential is T5/T8 office lighting. Li Cunzhong, associate director of the Ronda Electronic Optical Components Division, said that compared with the high unit price of LEDT5/T8 lamps in 2010, the mentality of building and lighting users and the on-site wait-and-see attitude began in the second quarter of 2011. The aspect will have a 180 degree reversal. In addition, it is worth noting that mainland China is the production center of the international lighting market. In 2011, the market for bulbs will surely shine. In addition, the Chinese government's policy of promoting energy conservation and carbon reduction has spared no effort in various policies. Under the blessing, the mainland LED lighting market will grow rapidly in 2011. LED supply and demand will be balanced this year In 2010, due to the large-scale popularization of LED backlight LCD TVs and the expansion of LED TV market penetration by international TV manufacturers, the supply of chips required for the lighting application market has been squeezed out, resulting in a situation in which LED chips are in short supply. In particular, small and medium power chips shared with the backlight market are particularly noticeable. However, with the blessing of the Chinese government's incentive subsidy policy, China's LED chip manufacturing plant purchased a large number of MOCVD machines for LED production equipment in 2010. It is expected that the volume and installed peak of MOCVD machines in China's LED chip manufacturing plants will fall in 2011. Therefore, LED chip supply and demand is expected to return to normal in 2011. However, some industry players pointed out that if the penetration rate of TV is rapidly increased to more than 60%, or the bulb lamp market is growing rapidly, the shortage of LED chips may continue until 2011. Focusing on LED lighting business opportunities, LED chip manufacturers have long been laid out for a long time, Ronda Li Cunzhong said that Longda Electronics can provide lighting products ranging from large, medium and small power packages, chips to optical modules. Demand, coupled with a complete LED industry chain structure, the above, middle and downstream one-stop design and production, so it can cope with the huge market demand and rapid changes, can quickly meet a variety of different customer specifications, in terms of capacity planning In response to market changes, Ronda's production capacity in 2011 will definitely increase with the needs of customers. Li Cunzhong also stressed that the current global LED backlight module factory and the world's largest lighting manufacturers are extremely important customers of Ronda. In terms of lighting, including various LED bulb modules and LEDT5/T8 tubes, Ronda has been supplying a large number of products since 2010. "However, due to important confidentiality agreements with customers, contract details Can't tell." He explained. Longda Electronics is currently the top three LED manufacturing companies in Taiwan. In addition, Cree has announced the launch of the industry's first illuminating LED array - XLampCXA20LED array, which can achieve the brightness of 60WA incandescent lamp with 11W power. This product is expected to accelerate LED lighting innovation. According to Cree, the CXA20 array is available in a single, uniform optical system, 22mm x 22mm compact package, and can be fixed with just two screws, helping customers who need a single device in their light source design to simplify the manufacturing process and use it. For traditional downlight applications, the CXA20 is 38% more lustrous than a 26W compact fluorescent (CFL) or 100W incandescent bulb, and has an input power of only 14W. At the same time, the CXA20LED array can be input at 11W and 27W respectively. Provides 1,050 lm and 2,000 lm of luminous flux at a power of 3000 K warm white temperature. Cree said that Cree will continue to introduce the most comprehensive range of lighting-grade LED products to the market, ensuring the best LED source for lighting applications, meeting the expectations of lighting manufacturers for high levels of lighting performance while simplifying indoor LED lighting. Design and manufacturing needs. Samples of the CXA20LED array are currently available and are expected to be in volume production by Q1 2011. LED chip and module costs will fall rapidly Looking forward to 2011, it is expected that the demand for medium-power chips and COB products will be greatly increased. As for the price changes, the industry generally believes that the development of the company's official research and development in the world and the expansion of the chip factory in 2010-2011 Under the production, the overall cost of LED chips and modules will decline rapidly in 2011. In addition, the continuous breakthrough of key technologies of LED chips will also drive down the overall price of LED lighting chips and modules, and the penetration rate of LEDs in the lighting market will be large. The increase is in the range. Investigate the global LED industry ecology. Basically, Europe and the United States and Japan have entered the LED industry and mastered patents earlier. Therefore, most of the pricing is based on a high unit price strategy. However, at present, LED chips and module suppliers in Europe, America, and Japan are upgrading. The market share has continuously adjusted the unit price of chips and modules. There is almost no price difference between the sales price of Taiwan and South Korea chip factories, forcing Taiwan and South Korea chip module factories to accelerate the development of new process technologies; improving the efficiency of their products, and LED chip factory contends. Ye Weifu, chairman of Everlight Electronics, said that the LED industry is in line with the demand for LED backlights in 2010. The demand for TV backlights continues to grow, and the growth rate in 2011 is expected to increase, and the LED lighting in 2010 is attracting attention. Year can be said to be a small step forward, and 2011 is expected to take a big step. Ye Yufu also pointed out that Taiwan's LED industry is quite complete in the middle and lower reaches, materials and equipment, and the follow-up development is quite expected. In terms of production capacity, Taiwan's LED production is currently the world's number one, but the output value is still under Japan. This is because key patents and technologies are still controlled by chip factories in Europe, America and Japan. Taiwan chip factories only adopt strategic Patent cross-licensing and other strategies, there are ways to survive under the attack of the US and Japan chip manufacturers. Furthermore, Taiwan's chip factory has the world's best chip research and development talents, which is also lacking in other countries' chip manufacturers, while mainland China has the world's largest market demand structure, with the best manpower, materials, etc. Precious resources, so the industry believes that in terms of the global LED industry ecological development, Taiwan and China will undoubtedly play a key role. LED lighting still needs to be overcome Although LED lighting is hot, there are still several problems that must be overcome. First, the cost and total luminous flux of LED lighting modules are still the biggest problems on the market. According to the industry, compared with the previous two years, the overall purchase cost of LED lighting modules will be significantly reduced in 2011, but the initial LED lighting module purchase cost is still much higher than traditional lighting about 5 times to 10 times. . Take the Japanese LED bulbs as an example. The 8.2W LED bulb white light system lumens 550lm-650lm is about 2,980 yen, equivalent to 250 yuan, as for the 23W traditional energy-saving bulb system luminous lumen 1,200lm-1,500lm market The price is about 30 yuan, which shows that consumers switch to LED bulbs, if you want to get the lumens of traditional energy-saving bulbs, you need to pay 15 times to 20 times the cost of construction, so how to significantly reduce LED The cost of lighting modules, as well as improving the production efficiency of LED chips, is a top priority for all current LED chip manufacturers. In response to the above-mentioned key issues in the LED lighting market, Li Cunzhong, associate director of the Ronda Electronic Optical Components Division, pointed out that Ronda has the advantages of backlight economies of scale and one-stop vertical integration, so that the basic cut-in LED lighting can be well played in the bulbs. On the other hand, Ronda has entered the general bulb market with the cost competitive advantage of mass production of the 5630, and can provide high-quality COB products by high-quality processes required for backlight production, further satisfying the high-order LED bulbs. In terms of lamps, due to the high degree of similarity to backlights, Ronda can replace existing low-power packages with similar packaged products to create a more competitive cost advantage. The direction of the chip industry Overall, if LED lighting in 2011 is to quickly introduce and replace traditional energy-saving lamps and incandescent lamps, it is necessary to start from two aspects, one for the brightness of the chip; the other is the standardization of the light source module. In terms of the improvement of the brightness of the chip, it is necessary to rely on the most upstream LED chip suppliers to continuously improve the LED chip process to improve the LED light efficiency and production yield, thereby reducing the production cost. For example, in 2010, OsramLED lighting efficiency has reached 134 lumens / watt, in order to improve the brightness of LED lighting, Osram is mainly from the self-enhanced blue LED grain light conversion efficiency, although the blue LED die light conversion efficiency is difficult to reach 100%, etc. The problem will lead to the white LED to increase the luminous efficiency to the upper limit. However, according to the research and development level, Osram now uses a blue LED die with a light conversion efficiency of 60%, and has a cold white LED with a luminous efficiency of 155 lumens per watt. (Driven at 350mA current). Observing Osram's LED lighting product planning, which has focused on building and situational lighting from 2007-2008, and focused on additional functional LED lighting applications in 2009-2010, gradually moving to general lighting, office/shop for 2010-2011 Lighting, therefore, OSRAM said that the company will focus on improving lighting quality and emphasizing LED lighting design. With Osram continuing to enrich LED-based solid-state lighting products, its solid-state lighting not only covers the 0.1-10W product line, but also has a wide range of applications. Osram minimizes 1W LED components, which is more advantageous in addition to thin design and light weight. Reduce costs and increase product reliability. In the standardization of the light source module, it is necessary to rely on various regulations and provisions for LED lighting module lamps, and further promote the institutionalization, standardization and simplification of the LED lighting module system in the world, especially the current market is full of messy and Uneven quality LED lighting products will not help build consumer confidence. Therefore, it is necessary to clearly formulate basic regulations for LED modules, so that the LED lighting market can be operated and eliminated, in order to improve the LED lighting market and build consumer confidence, so that there is a way to replace the traditional energy-saving lamps and white light market. Warm white new technology, the industry has a successful research and development. For the 'warm white' issue of LED lighting, Zhou Mingjun, general manager of Jingyuan Optoelectronics pointed out that the warm white light gives people a warm feeling. In the white light source for lighting, the proportion of warm white is as high as 60% or more, and the application of cool white is only About 30%. In order to achieve the warm white effect of LED lighting, it is generally a blue LED plus a red phosphor, but when it is warm white, it will sacrifice about 35% light output efficiency. The crystal photoelectric is a high-voltage blue LED using a semiconductor process. With the ultra-high efficiency red LED, it produces a warm white light source that combines ultra-high efficiency and high color rendering. In addition to breaking through the bottleneck of luminous efficiency, it can also display colorful colors in a real and natural way. Zhou Mingjun further pointed out that Jingyuan Optoelectronic's ultra-high efficiency warm white high-voltage light-emitting diode (HighVoltageLED, HV for short) can not only simplify the circuit design of the client AC/DC and reduce the efficiency loss of voltage drop, but also make the LED more efficient. The low-current mode emits light, and the LED has the characteristics of energy saving and long life. The bulbs and lamps developed by using this light source can exhibit the highest light-emitting efficiency and high color rendering. Zhou Mingjun believes that it can definitely create in the LED lighting market. Great business opportunities. Zhou Mingjun further analyzed the glory of the LED lighting industry from the perspective of technology development. He pointed out that incandescent bulbs are about to be banned, so the main competitor of LEDs is energy-saving lamps. LEDs must compete with them in terms of price. Therefore, the technical development focus of LED chips has shifted from lm/W to lm/ $; Moreover, in indoor lighting applications, HV/ACLED and DCLED compete with each other. 18650 battery is cylindrical rechargeable Lithium Ion Battery. for 18650 single cell, its size is high 65mm and diameter 18mm.18650 also has many advantages,such as high energy density, excellent charge retention, long cycle life, low self-discharge rate, low resistance, no memory effect and non-pollution. our company has been committed to manufacture 18650 battery pack for many years.
