LED outdoor lighting, dream into reality

The development of less Chinese led patented technology factors severely constrained LED outdoor lighting lamp China. In the fierce competition in the LED lighting market demand, only to master the LED patents and technology, can better ensure the quality and performance of products.

LED (LightEmittingDiode) is composed of electrical energy into visible light solid-state semiconductor light emitting diode, efficiently directly converted into electricity to light, has tens of thousands of hours of ~10 million hours of life. The utility model is composed of a wafer and an epoxy resin, which can work at low temperature and has good directivity of the light source. The utility model can be applied to the fields of landscape, safety, special and general lighting, etc. the market potential is immeasurable. Today, the high rate of concern is LED outdoor lighting.

Analysis of, China LED outdoor lighting situation

Global advocate low carbon life, saving energy and reducing carbon LED semiconductor lighting has become the era of "Darling".LED is a new generation of green light in the world, its high brightness, low heat, long life, non-toxic, known as the twenty-first Century most development of green lighting. LED lighting industry in China started in 1970s, the development of more than 40 years. China has now become the world's largest producer of lighting appliances and the second largest exporter of lighting appliances, LED as the leading industry in twenty-first Century outdoor lighting, there are deficiencies.

To LED outdoor lighting attention and application at home and abroad, the 1 degree of

1998, MITI issued the first phase of the "twenty-first Century plan" for the first time in the global light, to focus on LED, and the government also through the development of financial subsidies, tax incentives and loan preferential policies to stimulate LED technology. 2005, the U.S. government introduced the next generation lighting plan for the implementation of tax incentives for the LED industry. The large-scale LED street lighting renovation project in Losangeles to promote the use of LED street lamp. In China, the "national long-term science and technology development plan", LED lamps and other semiconductor lighting products are explicitly included in the "key areas and priority themes", the Ministry of science and technology of China also launched the "ten city lights" semiconductor lighting project, three year plan to install millions of light LED Road lamp, Guangdong "1000 in the one hundred thousand" LED street lamp demonstration project to accelerate progress, "Guangdong province LED street local standards" are promulgated, LED street construction obtained strong support of the relevant government departments.

LED outdoor lighting is not only widely used in city landscape, is also used in tunnel. At present, the highest concern is the application of LED street lamp. Losangeles will be within five years with 140000 LED lights, two city Pennsylvania umbre (Ambler) and Sunbury (Sunbury) this two city lights are all replaced by other countries generally use LED lights, LED lights, such as Japan, Korea etc.. In China, Dongguan plans three years of road lighting all the LED street lamps, Hainan plans to achieve in the past five years. The Beijing Olympic Games, Shanghai, World Expo, infrastructure Guangzhou Asian Games use a lot of LED outdoor lighting, such as the Guangzhou Asian Games venues Museum and the surrounding road home court, a total of 70000 new LED road lamps, Foshan stadium of South of the Five Ridges pearl stadium surrounding the 12 main roads, 12000 high-pressure sodium lamp retrofit LED lamp.

LEDinside research department data show that in 2010, the number of devices worldwide will reach about 870 thousand of the LED street lamp, LED street lamp which our market will grow by 60% and reached 400 thousand or more. In fact, China's annual demand for street market in 20 million or more, and showed a rising trend, experts predict that global LED lamp size of shipments in 2011 will reach 8 million light, permeability 8.5%, 2011 China's demand for global market share of about LED street 59%. LED Engineering Research Center (LIRC), is expected to install the amount of 2009-2011 will reach 1 million 120 thousand LED street lamp.

According to this, China's LED outdoor lighting industry is facing unprecedented opportunities and huge market potential, the development prospects are very optimistic.

2, China LED outdoor lighting industry current development status quo

(1) foreign monopoly LED patent, domestic patent less

In the world, in the LED patent leading manufacturer Nichia (Nichia), ToyodaGosei (TOYOTA), CREE (CREE), PhilipsLumileds (PHILPS lumens), Osram (OSRAM) and other well-known enterprises. It is reported that the application of LED related patents in the country, Japan accounted for 27.9% of global China accounted for only 9.34%. number of patent in China is far lower than Japan and the United States, especially in the upper reaches of the LED industry chain epitaxy, chip structure and other fields, the number of patent applications is even lower than that of Germany, Taiwan. Foreign enterprises pay more attention to the patent is also reflected in the maintenance, such as Japan Nichia tried to patent blue LED wants to monopolize market, to maintain the blue LED market by various means, and it was the successful development of GaN materials are not foreign sales, or only sold in japan.

(2) than Chinese high foreign LED Technology

LED industry development at present, the best countries were Japan, the United States, Germany, Taiwan Chinese also have better development, market share in Taiwan only ranked in Japan, ranked second in the world. Taiwan has low price chip and low price products beat Japan, forcing Japan towards the high price of the chip and the high price of product development, and Taiwan to seize the opportunity, combined with the experience of comprehensive development of downstream packaging, the upstream epitaxial wafers and chips, and continue to expand. Even so, Taiwan LED technology content is still a huge gap with Japan, Europe and the United states. Mainland China is much worse, especially in LED
