LED散熱技術之專利分析與TRIZ技法之創新設計
Patent Analysis and TRIZ Innovative Design for Dispersing Thermal Technology of LED
摘要
LED追求高亮度、高功率所衍生的最大麻煩就是散熱問題，因為LED晶片界面溫度(Junction Temperature)過高會影響發光效率及壽命，當產生的熱量無法有效排出，將導致界面溫度不斷升高，根據統計大約有70%的LED會因為過高的界面溫度而故障，進而影響到產品的市場滲透率，因此LED散熱技術的研究與發展，非常重要。 針對中華民國與美國進行專利檢索後，分別可以得到711筆與677筆LED散熱技術相關專利，將這些專利資訊進行專利地圖製作與分析後可以發現，中華民國與美國LED散熱技術目前均處於技術「成長期」，專利數量及專利權人數快速成長。中華民國LED散熱技術專利之發展比例為封裝基板改良佔47%，外加裝置模組佔34%，封裝材料及結構改良佔19%，而美國LED散熱技術專利之發展比例為外加裝置模組佔43%，封裝基板改良佔31%，封裝材料及結構改良佔26%，可以看出中華民國與美國LED散熱技術發展重點與方向並不相同。 經由專利檢索與分析後，選取技術應用最廣、相關專利數量最多的LED散熱技術專利；專利名稱：具熱管之LED散熱裝置(專利號：TWM 295889)做為本研究專利迴避設計之對象，經由分析其專利申請範圍後，提出設計問題，將問題透過TRIZ理論中矛盾矩陣的建構，運用技術創新手法與專利迴避鑑定，完成LED散熱技術之創新設計，此一過程可做為日後相關產業技術創新研發之參考。

The biggest challenge for LED with high lighting and high power, however, is the problem of heat dispersing . The life time and lighting efficiency of LED are negatively influenced by the high “Junction Temperature” when the heat from LED cannot be distributed out effectively. Generally speaking, about 70% of LED products are out of order due to the overabound ? high junction temperature, that would reduce the market penetration rate; therefore, The research and development of heat distribution technology for LED products are very important. After thorough survey of Taiwan and US patents, there are totally 711 and 677 patents related to the LED heat distribution technology, respectively. With the detailed patent map drawing and patent analysis, it is found that the technology is during the growth period and the number of the patents and invention are rapidly increasing. Out of these Taiwan patents, 47% is about bench packaging, 34% is about off-the-shelf module and 19% is about package material and structure. For US patents 31% is about bench packaging, 43% is about off-the-shelf module and 26% is about package material and structure. It is observed that the focus of the technology development of Taiwan and US is different. After patent survey and analysis, the patent, " An LED hest distribution device with heat tubes" (patent number: TWM 295889), was chosen as the candidate for our study about avoidance design due to its most widely employed and referenced property. After analyzing the range of patent claims, we achieved the innovation design for LED heat distribution technology by proposing the design problems, constructing the contradiction matrix through TRIZ theory, utilizing the technology innovation method and examine patent avoidance. The process is a technology innovation example for the related industrial.
