摘要
一种使用射频无电极等离子体技术的新型光源被应用到投影显示,它利用金属卤化物来避免使用难熔性金属电极带来的不利的化学性质,从而使低通量照度比的光源成为可能。它使得投影显示设备拥有长而稳定的寿命(无需更换灯泡)、宽广的色域和快速的启动时间。本文阐述了高强度放电(HID)的基本物理化学机理。该机理使得采用熔融石英封装并且具有高亮度、极好的色彩表现力和器壁稳定性的等离子光源成为可能。
A new light source developed for projection displays utilizing radio-frequency (rf) electrodes-less plasma technology makes possible low-é tendue light sources utilizing metal halides without the adverse chemistry associated with refractory metal electrodes. The results are projection-display applications that have long stable lifetimes (without re-lamping) plus wide color gamuts and fast start times. This article outlines the basic high-intensity-discharge (HID) physics and chemistry that enable high-brightness wall-stabilized plasma sources with excellent color rendition in fused-silica envelopes.
