摘要
利用色度学理论计算分析了传统弧光灯投影光源和LED投影光源两个实例的色度学特性,与传统弧光灯投影光源相比,LED投影光源具有更高的光谱能量利用率和更加丰富的色彩表现能力,完全符合数字投影机使用的sRGB彩色规范.采用时序脉冲驱动的单色LED作为投影光源能够在不牺牲色彩饱和度的情况下获得更高亮度的投影显示.因此LED可以替代传统的弧光灯光源以满足投影显示的色度特性要求.
The colorimetric properties of the conventional arc lamp and LED are calculated and analyzed by using the colorimetry theory. Comparing to the conventional arc lamp used as projection light source, LED illuminator has higher efficiency of the spectral power and better ability of color display. It can reach sRGB standard widely used by digital projectors. The single-color LED driven by temporal pulses will produce high-brightness projection display with saturate colors. Therefore, LED can take place of conventional arc lamp to satisfy the colorimetric requirement of the projection display.
