摘　　要：颜色的色品除用色坐标表示外,还可采用主波长和色纯度来表示。本文以色度学理论为基础,提出了一种提高LED灯具色纯度的方法,包括了获取待制作LED灯具的色系、选择LED类型、确定LED色坐标色域范围、制得各色灯罩等过程。实验结果表明采用此方法可有效提高LED灯具的色纯度,大大降低高色纯度LED灯具制作过程所需耗费成本;同时,可扩大LED灯具可选择的色域和主波长范围,增强了该制作方法的适用性。The chromaticity of color can be expressed by dominant wavelength and colorimetric purity in addition to chromaticity coordinates. Based on the theory of chromaticity, this paper proposes a method to improve the colorimetric purity of LED lamps, including the process of obtaining the color system of LED lamps to be made, selecting the type of LED, determining the color range of LED chromaticity coordinates, and making the colored lamp diffusers. The experimental results show that this method can effectively improve the colorimetric purity of LED lamps and greatly reduce the cost of the production process of high color purity LED lamps. At the same time, the selectable color gamut and dominant wavelength range of LED lamps can be improved, which enhances the applicability of the fabrication method.
