Intellectual property is the important embodiment of enterprise innovation achievements, enterprises as the intellectual property rights of personnel, management and layout, and familiarity with competitors and target market, is directly related to corporate strategy can be realized. The survey by questionnaire, understand LED lighting enterprise status, as well as the existing problems of intellectual property rights. Questionnaire data obtained at the same time, through field visits, read the information demand, to expand the comprehensive analysis and interpretation. 1, complete industry chain layout, technological innovation is given priority to with imitation and cooperation according to the guangdong business statistics, there are more than 15000 registered in guangdong province LED enterprises, more than 4000 enterprises above designated size. In the survey, actively provide questionnaire enterprises generally begun to take shape, micro and small enterprises accounted for only a few part of ( As shown in figure 3. 1) 。 A small micro enterprise under investigation, said the hope can through intellectual property rights, to obtain certification of new and high technology, and further for the government financial support. Despite the protection of intellectual property rights innovation, achieve rapid value-added enterprise development plays an important role, in the survival of small and medium-sized enterprise managers, it is difficult to have energy and financial resources should understand intellectual property rights. LED lighting industry cluster on the industrial layout is relatively complete, in various industrial level has the distribution of the enterprise, and enterprise usually involves a number of different industrial levels. In figure 3. 2, the LED lighting industry cluster encapsulation and lighting application of two key areas of technology, enterprises gather degree is higher. And denotation and chip area, due to the high technical content, input costs, raise the access bar, only a handful of companies involved in. Bdo embellish, caught in the semiconductor, kaixin pv rely on capital and technology advantages, such as guiding LED lighting industry gathering area extend upwards. In the field of drive power supply, bracket, MCPCB, agglomeration zone also have enterprise, realize the complete industry chain layout. Look from the LED source of enterprise technology, independent research and development is the main way of technology innovation, As shown in figure 3. 3) 。 International cooperation and domestic cooperation choose is less, a background in foreign enterprises have the possibility of foreign technology input, eighty percent of the domestic enterprise independent research and development core technology in general. Judging from the evidence of interviews, LED lighting applications enterprise mainly OEM products, or by import, purchase related raw materials, through the assembly and design, production of the final product, usually involves independent research and development of the technology for circuit design, and optical design technology application level.
