In this paper, we analyze the patents trends in LED general lighting through patents analysis in the area of worldwide LED general lighting industry. The correlation between the number of patent application and applicant has been analyzed by quantitative analysis according to its application year, country and core technology, and then the technology maturity has been presented. Futhermore, 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 show the patent network related to the technical components through the in-depth analysis, and summarized the bibliography and right scope of representative patent.
