植物生长灯光源能效的综合评价模型--基于主成分分析方法

The Complex Evaluation Model of Energy Efficiency of Light Resource During Plant Growing—Based on Principal Component Analysis Method

光是植物光合作用的能量源,植物生长灯人工补光技术的应用有助于增强农业产出能力、保障食品安全和加快我国现代农业发展。采用主成分分析方法直观定量地研究了普通白炽灯、卤钨灯、普通直管荧光灯、三基色荧光灯、紧凑型荧光灯、荧光高压汞灯、金属卤化物灯、高压钠灯和高频无极灯等光源的额定功率范围、光效、显色指数、色温与平均寿命等技术指标;识别出了植物生长灯光源技术指标数据的主要成分;主成分分析得分以高频无极灯得分最高,其它依次为高压钠灯、三基色荧光灯、荧光高压汞灯、紧凑型荧光灯、金属卤化物灯、普通直管荧光灯和普通白炽灯,卤钨灯最低。结果表明,模型能全面、客观和科学地对植物生长灯光源能效进行分析与综合评价,辅助植物生长灯在农业领域中的选择与应用。

Light is the energy resource of plant photosynthesis.The use of artificial light during plant growing is helpful for enhancing argiculture productivity,maintianing food safty and promoting the development of modern agriculture in our country.In this paper,principal component analysis method was hired to study some technical indexs of some light sources including the scope of rated power,luminous efficiency,color rendering index,color temperature and life expectancy,etc.,Principal component of technical indexs on light resource during plant growing are identified.Our analysis shows that the high-frequency electrodeless lamps got the highest score,the following are high pressure sodium lamp,three-color fluorescent,fluorescent high pressure mercury lamp,compact fluorescent lamps,metal halide lamps,straight tube fluorescent lamps,incandescent and halogen repectively.The result shows that our model can analyze and evaluate the efficiency of light resource during plant growing fully,objectively and scientifically,also,this model is benefit for the selection and application of auxilliary light resource during plant growing in the agriculture sector.
