According to the Southern Metropolis Daily, the 17th Guangzhou International Lighting Exhibition was held on the 9th. As the world's largest lighting exhibition, companies and brands in the world's top 500 lighting and LED fields such as Philips and OSRAM are gathering here. Pan Wenbo, the founder of Guangzhou International Lighting Exhibition, told Nandan that there were more than 2,600 exhibitors participating in this exhibition. The exhibits covered 21 exhibition halls including professional lighting, commercial lighting and LED raw materials.
The reporter learned from the "Lighting Industry's Latest Technology and Achievement Summit Forum" and "Asian LED Summit Forum" held during the same period. Since last year, many small and medium-sized LED companies have seen their orders drop and even closed down. However, on the other hand, large-scale enterprises with technological advantages set off a new wave of listings, and the state's 2.2 billion yuan subsidy policy is about to be introduced, and the speed of LED industry integration will be significantly accelerated.
LED market 500 billion temptation due to LED lighting with traditional lighting can not match the advantages of energy saving and environmental protection, last year, China issued a plan to phase out the incandescent lamp, decided that from October 1 this year, banned sales and imports of 100 watts and above incandescent lamps for general lighting As of October 1, 2016, the sale and import of incandescent lamps for general lighting of 15 W or more is prohibited. This means that incandescent lamps will gradually withdraw from the historical stage from this year, and the LED lighting curtain will open.
2.2 Billion Subsidy Accelerates LED Reuse Industry Accelerates Reorganization of Shuffles Pan Wenbo, founder of Guangzhou International Lighting Exhibition, said that China is a major country in the production and consumption of incandescent lamps, with 15 billion incandescent lamps in stock, and annual sales of 3.85 billion and 10.7 million respectively. Billion only. The official announcement of the phase-out of the incandescent lamp roadmap will form long-term benefits for the LED lighting industry and the energy-saving lamp industry. The market size formed by replacing only the existing incandescent lamps will reach several hundred billion yuan.
Although two years ago, China's LED lighting market share was less than 1%, but the country's determination to promote the semiconductor lighting industry has been set. According to the "12th Five-Year Plan" for the development of semiconductor lighting technology, by 2015, China's LED lighting industry will reach 500 billion yuan, LED lighting products will account for 30% of general lighting, and 20-30 leading enterprises will be fostered. 20 state-level industrial bases and 50 pilot demonstration cities of “Ten Cities and Ten Thousand Peoples†promoted China’s semiconductor lighting industry to enter the top three in the world.
2.2 billion subsidies to accelerate the popularity of LED Wang Lianghai, vice president of Tsinghua Tongfang Group view, LED accelerated bottlenecks, there are two, one is the LED photoelectric conversion efficiency needs to be improved, "The theoretical luminous efficiency and the actual index gap"; Second, the price, the current The price difference between LED lights on the market and ordinary energy-saving lamps is more than 5 times, and the price is about 40-100 yuan. Therefore, LED applications are currently more concentrated in the commercial rather than civilian areas.
"But the 2.2 billion subsidy will reduce the price of LED lights, or a drop of 15%-20%." Wang Lianghai said.
Recently, the State Council researched and determined policies and measures to promote the consumption of energy-saving home appliances and other products, and decided to arrange financial subsidies of 26.5 billion yuan, of which 2.2 billion yuan was used to support the promotion of energy-saving lamps and LED lighting fixtures.
Secretary of the China Semiconductor Lighting/LED Industry Association, Guan Baiyu, revealed to the South that the subsidy rules are expected to be introduced at the beginning of next month at the beginning of next month, and that the primary beneficiaries of state subsidies will be those large-scale LED companies with competitiveness.
Pan Yipeng marketing department Weng Yipeng said that LED is still a fight technology industry. "Taking the Panasonic LED bulb as an example, under the same illuminance, the LED bulb power is 4.4 watts and the life span is up to 40,000 hours, while the traditional bulb power reaches 20 watts, and only 10,000 hours are used. It can be seen that the LED lighting is in energy saving and environmental protection. The advantages."
Tongfang’s LED sales in this year can reach 2 billion. Wang Lianghai said that Tongfang has mastered key technologies in the LED industry such as substrate peeling of vertical structures, bonding of conductive and thermally conductive substrates, separation of chips, and nearly a hundred domestic patents.
Industry reshuffle speeds up the pace of "policy support and LED technology replacement, coupled with price storms to make this year's domestic LED market reshuffle integration speed. The international giants and competing domestic LED companies have become the leader in reshuffle." Pan Wenbo Say.
According to estimates, there are currently about 8,000 LED companies in the country, which are in a small and scattered state. “Many are just a few.†Lu Weiqiang, general manager of Guangzhou Shaoyang Lighting Co., Ltd., said that on the one hand, the opening is too large, blind expansion, and a serious excess production capacity; On the other hand, the production cycle of LED new products is about 3-6 months. The shortage of funds and SMEs lacking core technologies have no recourse.
Since last year, small and medium-sized LED companies have frequently closed down - as of the end of last year, only one city in Shenzhen, LED lighting companies have closed more than 80, Foshan, Guangdong, in 2011, there are nearly 10% of LED lighting companies closed down, Dongguan Zhongshan LED lighting companies also fell into the cold wave of closure.
As a barometer of the global lighting industry, Guangzhou International Lighting Fair's data also showed signs of increased industry concentration. According to Pan Wenbo, the number of companies that are currently holding the 17th Guangzhou International Lighting Exhibition has decreased by 12% from last year, by 2931. The number of homes has been reduced to 2,600, but the exhibition area has increased by 10% from last year to reach a record high of 220,000 square meters.
Lu Weiqiang said that the LED industry reshuffle will continue, "This year in the middle of the LED packaging company may have to die 40%; downstream SMEs to do LED applications to lose half."
However, people in the industry believe that the industry consolidation period can provide opportunities to become bigger and stronger, and companies should capture the huge business opportunities in the high-growth market.

Corner cube Prism is also named retroreflector or trihedral prism.In the corner cube prism,three reflecting surfaces are perpendicular to each other,like the side wall of the cube.The input surface is perpendicular to the cube diagonal. Disregarding the anlge of the incidence,the output beam is parallel to the input one,but it is of opposite direction. Inset of the several corner prisms, for better matching,their extrance exit surface is often hexagonal.In case of this prism the phenomenon of full internal reflection occurs so it is not necessary,(however it is possible)to put mirror coating on the reflecting faces. Normally the reflection surfaces are AL reflection coating, and then covered with Cu and Black painting.
Pyramid prism/Corner Cube Retroreflector is always used to reflect the beam entering the prism face, regardless of its orientation to the beam. Corner cubes are widely used where precision alignment is difficult.
