This year is the year of popularization of LED lighting, and the popularization of LED lighting will accelerate next year. The output value of LED lighting is expected to exceed that of traditional lighting next year, becoming a turning point in the lighting industry. At the same time, the integration of LED industry will intensify and there will be more mergers next year. Ruan Jun, executive deputy secretary general of the National Semiconductor Lighting Engineering Research and Development and Industry Alliance, accelerated popularization yesterday (9th) He said that the popularization of LED lighting will accelerate in 2015. Last year (China LED lighting products) Exports reached 5. 5 billion US dollars, reaching 7 billion US dollars in the third quarter of this year and expected to exceed 10 billion US dollars in the whole year, doubling the growth rate. Ruan Jun said. Ruan October 1 this year went on to say that China has eliminated incandescent lamps of more than 60 watts since; Europe and the United States have recovered their economies. Among several BRICS countries, the Indian government is also promoting the popularization of LED lighting, so the popularization of LED has accelerated. This year, the LED products of sunshine lighting and Foshan Lighting account for more than 60 ~ 70. Wang Donglei, chairman of dehaorunda and Rex lighting, also said: the popularity of LED lighting will reach a peak next year, with Rex's target of 50 products for LED lighting in 2015. According to UBS's forecast, 2013 ~ The overall growth rate of the lighting market in 2015 was 36, 37 and 38 respectively, of which the demand for residential LED lighting market increased by 157, 90 and 62 respectively during the same period. Industry insiders expect that the LED industry will grow by nearly 30 next year, with indoor LED lighting growing by as high as 50 ~ 60. Rex and op will account for of LED products next year ~ 60, these leading enterprises have a great influence, so the penetration rate of LED lighting will reach 50 next year and further reach 80 in 2017. 2015 is a year of rapid popularization of LED lighting and will be a turning point. The output value of LED lighting will exceed that of traditional lighting. The above-mentioned person said. There are more mergers. With the acceleration of popularization, another problem is competition. Ruan Jun said that small and medium-sized enterprises are under greater pressure. Industry mergers and acquisitions are a trend. Industry research also believes that the competition will be more intense next year. This year, many enterprises have tight cash flows, and some have fallen Gross profit margins and have been forced to close down. There will be more failures and mergers next year, because many small and medium-sized enterprises are difficult to continue. Many handicraft workshops have closed down this year, and larger enterprises will also close down next year. Recently, the packaging factory in Guangzhou has fallen in large quantities, because the quality and price are not comparable to those of listed companies, and the growth of scale and profit has fallen backwards. In recent years LED industry of merger one after another. Following Dehao Runda's acquisition of Rex and Tsinghua Tongfang's acquisition of zhenmingli, the night before (8th) Qinshang Optoelectronics also announced that it will acquire 51 shares of three small and medium-sized LED related companies. Industry analysts said that the previous products of qinshang Optoelectronics were mainly street lamps. With the popularity of civil lighting, they must also penetrate the terminal channels. This year, they have been looking for mergers and acquisitions, and have talked about many companies. Among the three small and medium-sized companies purchased by qinshang Optronics this time, one is a traditional lighting company that has been transformed into LED lighting and has channels; Another one is doing energy-saving certification. There is more room for mergers and acquisitions in the LED chip field. Wang Donglei believes that the domestic peak is 60 ~ Of the 70 LED chip factories, some are not well managed and have stopped production. Now there are only more than 20. The LED chip project has a huge investment. Since most of the LED chip factories are supported by local governments, it is difficult to integrate. However, nearly a lot (Chip)The factory came to me (Talk about mergers)Wang Donglei revealed. However, he believes that most of them will be eliminated slowly and naturally, and there are not many of them with acquisition value. The integration of LED chips in China and in China is necessary. As for the technical direction, industry insiders believe that LED technology has changed greatly, and the technical directions of upstream, midstream and downstream have not been determined. Flip-chip currently only replaces formal chips in the field of high power, whether it can become a trend remains to be seen. Ruan believes that LED flip-chip is the trend because the efficiency of a single chip is improved and the cost is reduced, but it takes time for packaging factories and customers to accept it.

Some people used to describe the 2013 of China's household industry as moving forward in difficulty, but used pain and happiness to describe the Chinese lamp industry. According to statistics, on the premise of environmental difficulties in the building materials and home furnishing industry, lamp enterprises have achieved 100 performance growth against the market. In the new 2014, will the lighting industry continue this brilliant performance? What new trend will the lamp industry usher in? The small editor intends to analyze and discuss the market environment, consumption upgrading, channel reform, product design, service concept change and other trends, so as to ask the way for the lighting industry in 2014. The third plenary session of the 18th CPC Central Committee emphasizes the construction of urban-rural integration. Under the general trend of urbanization of agricultural population, consumption is also facing upgrading, lamps also have a good opportunity to enter thousands of peasant families. The key reform direction decided by the central urbanization conference is to vigorously develop small towns, expand small and medium-sized cities and restrict megacities. Lamp enterprises will face a huge rural market. With the acceleration of the process of urban-rural integration and the increase of farmers' income, the rural market will become a potential cake. Intelligent lighting industry and traditional battle intelligent lighting is not a new topic in the industry. As early as a few years ago, intelligent lighting has appeared frequently in the industry, but at the same time, most intelligent lighting stays at the stage of high school and has not really spread among consumption. The big advantage of traditional personalized customized lamps is that they can meet different specific needs according to different groups of people. However, in the process of research and development of intelligent lamps, it is bound to require expensive research funds. This expenditure will eventually be borne by consumers of intelligent lighting, therefore, intelligent lighting can only take the consumption route in the initial stage of implementation, and it is difficult to popularize in the middle market. Suitable aging and environmental protection of spring 2013, China usher in a elderly population growth peak aging population to 2. 0. 2 billion, the aging level reached 14. 8. Industry insiders said that with the acceleration of the aging of the social population, the household industry is also seeking opportunities for aging. In product design, it will pay more attention to the needs of the elderly. At the same time, with the frequent occurrence of smog weather in major provinces of our country, environmental protection has become a hot topic of common concern to consumers. Serious environmental pollution is the heavy price paid by the extensive economic development for more than 30 years. Therefore, the future energy conservation and environmental protection industry is the development direction, and the same is true for lamp products. As the core part of the room, personalized lamps are obviously of great significance to consumers whether they are environmentally friendly. Health, environmental protection and green road will be the main body of the lighting industry in the future, and more consumers will incorporate environmental protection into the reference of product selection. The standard implements and eliminates the chaos in the lamp market. The personalized lamp industry has completed the process from scratch, from existence to development, and now forms a concept of home life. With such rapid development, on the one hand, people in the industry are more and more optimistic about the prospect of personalized lamps; However, on the other hand, the rapid pace of development has failed to keep up with the relevant standards and norms of the personalized lighting industry, resulting in frequent chaos in the customized lighting industry. Nowadays, it is the common understanding of many lamp enterprises to change from selling products to selling services. In today's personalized lighting industry, from consumer selection of samples to styles, to product wattage, installation and distribution, all are linked to the service of merchants, the advantages and disadvantages of the service have a direct impact on the brand image of lighting enterprises. Jiuzheng building materials network interprets 2014 and looks forward to the future of the industry. Under the influence of many favorable policies, driven by channel changes, and promoted by the upgrading of service concepts, china's lighting industry is bound to reach a higher peak and popularize more and more Chinese families with a more perfect and mature attitude!

Since the beginning of this year, Blu-ray LED has been hit by oversupply and is under pressure on prices, resulting in weak operation of leijing factory in the first half of this year. However, recently, upstream and downstream manufacturers have released the message of price reduction and deceleration on sapphire substrates and LED lighting. The penetration rate of LED lighting in 2014 will be from 8 ~ 10 climbed to 20 at one stroke, becoming another major force in digesting chip production capacity. Yiguang said that the price of mainstream LED lighting fell by more than 20 this year. Although it is difficult to get rid of the trend of price reduction next year, the decline has the opportunity to be controlled within 20, which is better than this year. Yiguang currently adopts a dual-brand strategy for LED lighting, including EVERLIGHT and ZENANO, which have not officially entered a profit-making outbreak period. However, with the low price of chips and the rising demand for terminals, yiguang estimates that the penetration rate of LED lighting will rise to 20 next year, compared with only 8 ~ this year ~ The penetration rate of 10 showed a significant growth. In addition in sapphire substrate on price also temporarily bottoming out. Trend sapphire substrate factory pointed out that this year 2nd Season ~ 4th season sapphire substrate of ASP change not than in earlier of 9 Season ~ In the 10th quarter, the price has reached the bottom, and it remains to be seen whether the price will show a V-shaped trend or an L-shaped trend.

What is the LED an optical design and the secondary optical design? Whether all the LED contains an optical design and the secondary optical design? Today we're going to simple know about the basic knowledge of the LED optical design, take you into the LED field. A, an optical LED chips encapsulation into LED optoelectronic components, a first optical design, in order to solve the LED light Angle, light intensity, and the size of the luminous flux, intensity distribution, the range of color temperature and distribution. This is known as an optical design. So an optical design is mainly on the chip, stents, the grain of the three elements of design. LED light source is mainly two, secondary optical intensity distribution form secondary optical design for high power LED lighting is generally high power LED has a lens, light Angle of 120 degrees or so. Secondary optics is to again after a lens, the light through an optical lens to change its optical properties. High power LED lighting components before he became a lighting products, generally must carry on the two optical design. So the secondary optical design is mainly to optimization design of LED lighting appliances, LED light source, the secondary optical light distribution design, throw light on large area and flood lighting light distribution needs are most urgent. Through the secondary optical design technique, design and reflection cup and multiple optical lens and the aspherical optical surfaces, can significantly improve the efficiency of the device get light. Three, the action of the secondary optical light spread to the broader scope, and change the light intensity distribution wide beam assembled into narrower beam four, secondary optical design principle of any point of the intensity of illumination in the lighting area are made by many different points of the light source of light, and through the optical lighting system formed after the redistribution of superposition. Optical illumination optical system generally includes the LED light source, optical system and the planar five, LED optical illumination system design method, and the optical system design requirements are proposed according to the requirement to collect for the parameter conditions of the optical system is necessary, in the optical 'impossible' is 'unreasonable' demands out optical system overall design layout, the design of the optical parts according to design requirements to optimize optical effect, draw product drawings are usually performed by computer-aided software, consider molding products processing, the output image file six, seven, LED lamps and lanterns use scenarios and test simulation of optical system classification 1.

In the past few years, due to the impact of the Japanese nuclear disaster, and the high energy prices, the awareness of the green energy industry has once again risen, and the related industries have returned to the growth track. However, in the past, the importance of open source was emphasized. Manufacturers have successively invested in the manufacture of solar panels and the improvement of conversion efficiency. However, after years of limited progress, they have been unable to break through the bottleneck of 20 conversion efficiency. In this case, the focus is gradually shifted to the power-saving efficiency of LED that can be throttled on a large scale. This trend began to take shape in the second half of 2013 and is expected to create an explosive period of LED lighting growth in the next three years from 2014. The big heads of the last wave of LED industry originated from the end of 2008 when the financial tsunami occurred. Samsung launched a thin LED backlight TV, which was unexpectedly sold and started an 18-month growth cycle of led TV. But Japan and China are stunned, and this beautiful thing has a huge reversal in 2011. As a result of the mainland's promotion of the 12th Five-Year Plan and its large subsidy of MOCVD machines, the mainland has more than 1,000 MOCVD machines worldwide. A large amount of production capacity was opened, which caused the price of LED backlight to collapse. Since then, LED has fallen into the freezing period. The whole industry has also entered a long-term capacity adjustment from the second half of 2011 until the end of last year. Another reason for the LED industry to enter the capacity adjustment is the delay of the rise of the LED lighting industry. The reason for the failure of the ten-city street lamp plan, in addition to the heat dissipation problem can not be solved, the bulb manufacturers are not willing to support LED lighting is another main reason. At that time, LED bulbs were too expensive to attract the favor of ordinary consumers, which was another reason why they could not be promoted. For various reasons, the original expectation that LED lighting will replace General Lighting in 2012 and add new kinetic energy to the LED industry has failed. As a result, from 2012 to the first half of 2013, the original expansion manufacturers were forced to adjust their production capacity. the LED industry is dead. This dead silence was broken in the second half of 2013 by CREE, the first American manufacturer to jump into LED lighting. In order to fill the production capacity, Cree officially entered the US lighting market in 2013 at a price of 9. . The $97 40 Watt, with a price of 12. The $97 60 watt replacement bulb. Such an affordable price has finally stirred up in the lighting market, causing huge repercussions. In the second half of 2013, Cree sold more than 8 million sets of 3 sets of light gun sets in the United States. The profit was also positively reflected in Cree's financial report last year. 2013 4th Season lighting business accounted for Cree Total revenue accounted for than by the year before last of 35 up to 42 revenue years growth 42 is 3 A Business Department in growth amazing of. After Cree invaded the lighting industry, major lighting manufacturers also followed suit one after another. It is expected that the penetration rate of LED lighting will increase from 8 to 15 in 2014. In 20 and, there will be more opportunities to reach 40, injecting upward momentum into the LED industry.
