On April 15, 2013, professor zhang was invited to the company of southeast university lectures, tech organization denotation and chips as well as the related department staff listened to professor zhang about studies of GaN based LED light extraction efficiency of technical lecture, professor zhang GaN LED light extraction efficiency was studied for many years, has a wealth of experience and unique insights, analysis the characteristics of the light from many sided, especially how to reduce the light absorption and how to maximum extent, improve the efficiency of the light, put forward a new type of composite plating back LED structure, put forward the design theory of curve, create efficient chips, under the premise that guarantees the stability of the chip, optical power can be increased by 43.1%, but also a lot of good methods are put forward. The lecture and chip technology improvement of epitaxial design has a lot of help. During the many technical personnel with professor zhang had extensive discussions, learned a lot of theoretical knowledge and combined with the practice of skills and experience, this kind of school and enterprise combined with practice is of great help to promote the development of enterprise, at the same time, the school also learned that the enterprise needs to what kind of knowledge, also can promote technical progress and clear direction, more can promote the great development of China's LED industry.
