技術說明

由於發光二極體(LED)具有耗電少、效率高、壽命長等特性，亦無汞污染等環保問題，且將之應用於各種平面顯示器的背光源能獲得優越的色彩表現，使得LED於顯示器中的應用在近幾年來受到高度重視與研究。本發明是有關於一種具有提升光指向性之反射裝置。以應用於液晶背光模組為例但不限應用於背光模組，且不限於點光源系統，而提出之發明。本發明揭露一種具有提升光指向性之反射裝置，且不需使用任何光學薄膜的狀況下也能得到均勻且光指向性良好之光源模組。 Light emitting diodes (LEDs) have the characteristics of low power consumption, high efficiency, long lifetime, etc., as well as mercury-free environmental advantage. Thus, the application of LEDs in displays has drawn great attention in the recent years. The present invention is generally related to a method for light directivity, and more particularly to a method for enhancing light directivity of a lighting apparatus. The present invention provides a backlight unit having a reflecting device for enhancing light directivity. But it can be used to other demands and the light sources do not be limited by a dot light source. By such a reflecting device provided to surround the light source to control light directivity, the backlight unit in a LCD does not need other optical components, such as diffuser sheet, diffuser plane, or brightness enhancement film (BEF), to improve the optical performance.
