基于光谱分析的鲜肉灯研究

Research on Fresh Meat Lamp Based on Spectral Analysis

随着LED技术的发展,鲜肉灯照明的研究变得活跃,但大多数鲜肉灯的研究都是基于人的主观感受,缺乏数据的量化表征。本文选用了6种普通的鲜肉灯,通过测量鲜肉灯的光谱,分析这些鲜肉灯的峰值波长、半峰宽特性。另外,通过测量得到光谱数据、中心照度分布值以及相关色温,同时根据光谱数据计算得到了鲜肉灯的一般显色指数R_(a)、特殊显色指数R_(9)、色彩保真度指数R_(f)与色彩饱和度指数Rg等显色性指标,结合这些指标来对这些光源形成的生鲜光环境进行分析与评价,为健康、舒适以及不同目的的鲜肉灯选择提供依据。

With the development of LED technology,the research on fresh lamp lighting has become active,but most of the research on fresh lamps is based on people's subjective feelings,and there is a lack of quantitative representation of data.In this paper,six kinds of ordinary fresh meat lamps were selected,and the peak wavelength and half-peak width characteristics of these fresh meat lamps were analyzed by measuring the spectrum of lamps.In addition,the general color rendering index R_(a),special color rendering index R_(9),correlation color temperature(CCT)and illuminance of the fresh meat lamps were obtained through spectral calculation,and the fresh light environment formed by these light sources was analyzed and evaluated by combining these indicators,so as to provide a basis for the selection of fresh meat lamps for health,comfort and different purposes.
