提出一种基于单色LED补偿白光LED技术,模拟日光在可见光范围内的光谱。实际调研了大功率单色LED现状,采用光子在二维空间内联合态密度函数作为单色LED的光谱辐射模型,建立LED模拟仿真数据库。通过求解超定方程组的非负最小二乘解,优化选择不同峰值波长以及半高宽的单色LED与白光LED组合,实现对目标光谱的匹配及太阳光谱的再现。对比研究了白光LED补偿技术和纯单色LED组装技术,并分析了不同种类LED组合对太阳光谱的模拟情况。结果表明,白光LED补偿技术拟合太阳光谱相关指数达到90.74%,优于纯单色LED组装技术。并且当单色LED种类减少时,白光LED补偿技术相比纯单色LED组装技术可以实现更好的模拟效果。该方法对实现基于LED类日光照明具有较好的指导意义。
A method based on white LED compensated with monochromatic LEDs was proposed to realize the spectrum matching of solar spectrum in the visible range. The market of high-power monochromatic LEDs was researched and the model of joint-density-of-state according to the characteristics of monochromatic LED spectrum was used as the mathematical model. A database was established with the model of joint-density-of-state. Different kinds of monochromatic LEDs combination were optimized to compensate with the white LED by solving non-negative least square solution of overdetermined equation. The reproduction of solar spectrum was achieved. The methods of white LED compensation and multiple monochromatic LEDs spectral assembly were compared and the fitting effect of different LED combination matching solar spectrum was analyzed. The results show that the method of white LED compensated with monochromatic LEDs optimizes the simulated solar spectrum with the fitting correlation index of 90.74%
better than the method of monochromatic LEDs spectral assembly. When the number of LED types decrease
the former has better effect in simulating solar spectrum. The experimental data can be instructive to realize the different degree of solar-like lighting by selecting suitable LEDs.
