摘要

带有定制标准荧光灯的传统照明隔间在工业中用于彩色材料的测试和质量控制。在这项研究中,我们构建了一个基于LED光谱可调光源(LSTL)的照明室,该光源实现了一个简单的强制空气冷却系统。LSTL由UV-LED、单色LED和准黄色LED组成,覆盖340至800nm的波长范围。为了弥补在520至625nm波长范围内缺乏合适的绿色LED的问题,LSTL使用了准黄色LED,该LED是通过用高通滤光器切割白色LED的蓝色光谱制成的。重建的光谱比D65荧光灯更接近CIE标准光源,并且光强的波动具有相当好的性质。此外,我们还通过与D65标准荧光灯的比较,讨论了LSTL的优点和改进。

Study on Realization of CIE Standard Illuminant by LED Spectrally Tunable Light Source with UV-LED and Visible-LED
Conventional lighting booths with custom standard fluorescent lights are used in industry for testing and quality control of color materials. In this study, we constructed a lighting booth based on an LED spectrally tunable light source (LSTL) that implemented a simple forced air-cooling system. The LSTL was composed of a UV-LED, single color LED, and quasi-yellow LED to cover the wavelength range from 340 to 800 nm. To compensate for the lack of appropriate green LEDs in the wavelength range from 520 to 625 nm, the LSTL used the quasi-yellow LED, which was made by cutting the blue spectrum of a white LED with a long-pass optical filter. The reconstructed spectrum was more approximate CIE standard illuminant than a D65 fluorescent lamp, and the fluctuation of optical intensity was of considerable well property. In addition, we also discussed advantages of and improvements enabled with LSTL through a comparison with D65 standard fluorescent lamps.
