摘要
本文公开了一种用于植物生长的特定光谱模拟照明装置及模拟方法,突破了单光源设计思路,设计基于LED组合的六边形可扩展光源阵列,通过单片机控制和采用电感式开关稳流电源实现受控供电,采用单色标定方法确定光源构型参数,利用最小二乘非线性曲线拟合实现了对特定光谱的模拟。装置具有"模拟特定光谱、轻小可靠高效、便于扩展、通用性强"的优点。仿真试验结果表明,本方法可以有针对性地灵活模拟特定生物的可见光吸收光谱,解决了生物培养中如何高效灵活给光的技术难题,为生物科学研究、特殊环境生物培养和保鲜等提供了新的技术手段。
This topic offers a special analog spectroscopic lighting device and its method which applies to helping the growth of plants. It breaks through the old design idea by using single light source, based on the LED hexagon extensible light source array, achieving the controlled power supply by SCM control and electric sensed switch, confirming the light sources specification by single color calibration, and finally succeed to simulate the specified spectrum by least squares nonlinear curve fitting. The device is featured as ＂simulating specified spectrum, light and handy, stable, high efficiency, expandable, universal application＂, etc. This simulation test result proved that we can flexibly simulate specified plant＇s visible light absorbing spectrum, which settled the technical issue how to provide light to plants high efficiently while planting, also offers new technical methods for biological research, plant nurturing in special environment and preservation
