摘要(Abstract)：

广告灯箱海报的颜色鲜艳生动程度不仅受印刷技术和成本的限制,还受照明光源的影响:照射光源的色域面积在一定范围内上越大,被照射物体颜色看起来越鲜艳,并越受人喜欢。本文在一款白光LED广告灯的基础上通过叠加单色光使其光源色域面积增大。通过数值计算得到所需叠加的单色光波长范围在500～550 nm和620～680 nm。在此基础上,我们制作了叠加520 nm灯珠和叠加680 nm灯珠的LED广告灯箱,并通过视觉实验检测其视觉效果。结果表明叠加680 nm单色光后的广告灯箱上广告海报颜色看起来更鲜艳生动。
The vivid color of the advertisement poster is not only limited by printing technology and cost,but also by the illumination lighting source: people often prefer illumination that enhances object chroma and larger gamut area enhance object chroma. To increase the gamut area of advertising lamp,the monochromatic light with different peak wavelength was added to the white LED advertising light. By numerical calculation,the gamut of advertising light became larger after added monochromatic light with500 ～ 550 nm and 620 ～ 680 nm. Based upon this,the advertising lamp added 520 nm LED lamp and the advertising lamp added 690 nm LED lamp was made and a visual experiment was conducted to investigate the illumination effect. The results show that the advertising lamp added 680 nm LED lamp makes the poster looks more vivid.
