摘要
以色度学理论为基础,分析和测试了激光与LED混合新型投影光源的亮度和色域覆盖范围,并与传统的超高压水银弧光灯进行比较.新型投影光源不仅亮度很高,在使用较长时间后亮度无明显衰减,而且色域覆盖范围更加接近与人眼,色彩表现更加丰富、有层次感,真正符合高亮度、高色彩还原能力的投影显示效果的需求.采用激光与LED相结合的方式作为照明光源,既解决了单独使用LED光源时亮度始终不够的问题,又能有效地减少环境污染.因此,激光和LED混合投影光源凭借无法比拟的优势可以替代传统光源以满足投影显示色度学的要求.
Abstract
Based on the theory of colorimetry,brightness and coverage of color gamut of laser and LED hybrid projection sources were measured and analyzed.Compared with the traditional ultra-high-pressure mercury arc lamp,the new projection sources possessed higher brightness.The brightness had no obvious attenuation after using for a long time.The coverage of color gamut was more colser to the human’s eye.Meanwhile,the color performace was still further abundant,which met the projection display requirements of high brightness and high color reproduction capability.
