摘要
为实现在植物不同生长阶段按需精确定量补光,提出一种考虑植物不同生长期所需光质不同的LED补光系统的设计方案。该系统实时监测植物生长环境中不同光质的光照强度以及环境温度,根据系统预设算法精确计算作物实际需要的补光量,并以PWM调光方式控制通过LED的电流进而调控红、蓝LED植物补光灯的亮度。该补光系统可实现为植物提供最适合的光照条件的目标,不存在光源浪费问题,实现节能化精确补光。
A lighting system with LED providing different light quality was designed to achieve quantitative supplementary lighting at different stages of plant growth.The system could monitor illumination of light quality with specific wavelength in real-time,ambient temperature,the amount of light that plant in need,and control the brightness of red,blue LED lights by pulse width modulation（PWM）signal.The system could be used for various plants at diverse growth stages under disparate environments with different demand in light quantity and quality with accurate,intelligent,low-power features.The system could prevent plants from light deficiency or excess and improve energy efficiency.
