チップオンボードLEDは、新しいLED照明光源モジュールで、パッケージオンボード(POB)形式の替わりにチップオンボード(COB)形式で収益回路を基板上に付着させたものです。この方式は、LED照明の価格低下につながる新技術として、関係者からの大きな注目を集めています。また、サイズの小ささから設計の柔軟性が増すこと、光学システムを一つしか使わないことも大きな利点となっています。その利点を生かすために、各企業は新製品の開発に積極的に取り組んでいますが、その結果として特許紛争が増加する可能性があります。
当レポートでは、世界各国のチップオンボード(COB)LED照明の関連特許の出願・取得状況について調査し、チップオンボードLED(発光ダイオード)の技術的特性や、全体的な特許出願状況(国・年度・出願者別動向、希少シェアなど)、分野別の主要特許情報(6分野、合計735件)といった情報を盛り込んで、概略以下の構成でお届けします。
This report was written to provide information on patent technology trends of Korea and foreign countries on recent biggest issue [COB LED]
LED lighting has become a major energy saving technology having better luminance efficiency than incandescent or fluorescent lighting. As Europe is banning incandescent lighting from 2012 the LED lighting market is expected to enter a growth period in 2013. However, in order for the LED lighting market to increase rapidly, there are requirements for high power low cost LED lighting products.
COB LED is a new LED light source module technology which attaches integrated circuit on the substrate in COB (Chip On Board) form instead of POB (Package On Board) form. COB LED is receiving much attention as a new technology that will reduce the price of LED lighting.
Since the size of the COB LED is small it provides excellent design flexibility and due to the fact that COB LED uses only a single optical system instead of multiple optical systems it can achieve superior light distribution pattern than general LED products. In order to take advantage of the new COB technology many companies are putting out new COB LED products and actively developing the technology and as result patent disputes are expected in this area.
For patent analysis, among 13,738 of raw patent information data which was obtained by repeating each company's patent applicant search for 6 rounds, 735 validated patents on Chip-on-Board LED were selected by removing duplicate patents and patents of other technology areas (noise). The 735 validated patents are classified into chip mounting technology, encapsulation technology, multi-chip array technology, PCB technology, luminous efficiency technology and heat dissipation technology. The details of valid patents are given in the table below.
The report provides recent patent application trend and key patents of COB LED technology and is expected to help establish the direction for technology development of COB LED and prevent future patent disputes. (Total of 277 pages)
