But in cities and so on Tianjin, Yangzhou, but also enlarged to has been related the talented person the raise and the introduction. For instance Tianjin has established the domestic first semiconductor lighting techniques and the project characteristic specialty greatly in the Tianjin labor,development promoted
trains the semiconductor illumination specialized technology talented person.


Yangzhou is the high salary hires the correlation technique talented person, this city start “raises Jin Fengyin only then to plan green”, sets up the introduction of talent special fund 40,000,000 Yuan specially, uses in starting an undertaking the innovation commanding troops talented person, outstanding doctor talented person's fund subsidization and the related operational funding. Under talented person's raise and the introduction, will send long-term for these urban LED industry broadcast “the hope seed”.


Support nationality industry perfect industry chain It is well known, the LED upstream's chip and the extension piece occupied the profession majority of profits, but seals and the application profit comparatively appears quite meager. But counts demonstrated that our country 70% semiconductor illumination Production enterprise concentrates in the industrial downstream,conserves energy
the domestically produced LED extension material, the chip by low-grade primarily, 80% above power LED chip, component dependence import. Therefore, supports the national industry to develop the action which to the upstream into many cities take a long-range approach.


Wuhan to speed up the domestically produced chip application, after the demonstration project examination, the energy conservation effect will achieve 40% above the local upstream, the middle reaches, the downstream industry unified body LED illumination product to include the government central buying table of contents; Nanchang has formed the engineering project advancement leading group and the technological innovation alliance specially, the middle and upper reaches core technologies superiority which the use has,lanterns enterprise
the cultivation guidance enterprise independent innovation, increases in the extension chip domain words power; The Dongguan cultivation brand Leading enterprise, enlarges to the upstream project introduction work and the policy support;


Yangzhou “ten city ten thousand” the project is the turning point, the guidance enterprise tries to solve the key key technologies difficult problem, makes a connection with the industrial technology chain, released 1,000,000,000 Yuan MOCVD equipment purchase subsidy policy, the enterprise has purchased achieves the international advanced level the MOCVD equipment, gave 800 ~ 10,000,000 Yuan/subsidies, impelled the industry to the high-end development. Many cities try to raise the national enterprise, supports the national enterprise to the industrial chain's upstream development.


In addition, in “ten city ten thousand” in pilot work, but also has many cities to devote to the related standard establishment. For instance Nanchang drafted formulates the LED street light provincial standard, Guangdong Province has also released the related provincial standard. These actions, sped up these experiment site city to promote LED the step, simultaneously also gave other cities to set up the example.


The radiation,inverter welding machine this puzzles LED to illuminate the large-scale application technical difficult problem, finally by a Chinese Enterprise attacking a fortified position! Recently, (next was called sea rainbow science and technology) from Chongqing sea rainbow science and technology Limited liability company to find that its own research and development “the lamp bead radiator low temperature welds the technology (LTS) to be possible straight” the thorough settlement to be puzzled by the LED illumination domain many year radiation difficult problems. May enhance the LED lamps and lanterns' light effect and the service life large scale through this technology, the heat conduction performance will enhance above 10 times.


This technology's breakthrough has attracted the profession judgment all of a sudden, also let the sea rainbow science and technology become famous overnight, stands the LED profession front. Takes seriously day by day along with the people to the environmental protection with the LED profession development, the big area promotion high efficiency LED application future has developed tendency.


However, since long high efficiency LED, although the merit are many, but is also very high to the radiation specification, the LED junction temperature achieves when certain altitude LED very quick will produce the light to fade, causes the LED life to drop. But the sea rainbow science and technology “the lamp bead radiator low temperature bonding technique” has brought the significant breakthrough, opened the profession to develop “the brow” forward.
