LED植物补光系统控制研究进展

Research Progress of LED Plant Supplementary Light System Control

随着世界人口的持续增长,人们对粮食的需求急剧增长,这催生了LED植物补光技术的发展。LED植物补光技术就是利用LED光源对植物进行照射来补充太阳光的不足,以提高作物产量和满足食物供应的要求。现在的植物补光系统采用LED作为光源对植物进行补光,相比于其他传统的人工光源,能更好地满足植物生长需求。植物补光系统的应用越来越多,对于控制LED的发光强度来满足植物生长需求显得十分必要。本文首先介绍了LED植物补光系统的原理和结构,然后介绍了调光方式,最后介绍了系统控制的研究进展。

With the continuous growth of the world’s population,people’s demand for food has increased sharply,which has given birth to the development of LED plant lighting technology.The LED plant supplement light technology is to use LED light sources to irradiate plants to supplement the lack of sunlight,so as to increase crop yields and meet the requirements of food supply.The current plant supplement light system uses LED as a light source to supplement light for plants.Compared with other traditional artificial light sources,it can better meet the growth needs of plants.There are more and more applications of plant lighting systems,and it is very necessary to control the luminous intensity of LEDs to meet the needs of plant growth.This article first introduces the principle and structure of the LED plant supplement light system,then introduces the dimming method,and finally introduces the research progress of the system control.
