In this paper, we analysis the development possibility of detail technology in LED general lighting base on patent share and increase rate during latest 10 years. And patent activity index of subject countries are calculated and annual patent application trend is analyzed in order to grasp the patent activity and interest technical field in each country. And, the technical levels and technological edges of invested countries(Korea, US, Japan, Europe) have been quantitatively estimated base on share, citation index and impact factor of patent. Finally, we discuss the technical development strategies in LED general lighting through patents analysis in the area of worldwide LED general lighting industry.
