Evaluation Index Study of Students’ Physiological Rhythm Effects under Fluorescent Lamp and LED

Abstract

The influence of artificial classroom light source’s colour temperature to students’ learning efficiency and physiology rhythm is the focus of this study. An experiment compares a subjects’ learning efficiency, asthenopia and brain fag under different luminance level of three typical colour temperatures from T5 fluorescent lamps and LED. Using comprehensive index ε and norm identification Ψ for quantitative evaluation and testing under different lighting environments, we determined the best colour temperature of two experimental light sources. We also determined the best combinations of illuminance value and the colour temperature that should be avoided in classroom lighting. Experiment shows that spectrum difference obviously effects comprehensive index ε and norm identification Ψ. For learning efficiency and health of people, there need to be improvement in the spectrum of fluorescent lamps and LEDs

The Effects of Eye Illuminance Distribution in the Horizontal Field of View on Human Performance in a Home Paper-Based Learning Situation

“…where R is the number of reading letters/rings, D is the number of letters/rings that ought to be deleted, and E is the number of errors and omissions [45].…”

Comparative analysis of light environment perception, eye movement and physiology in university professional classroom based on virtual reality experiment

“…The higher the index is, the more conducive it is to improve the learning efficiency of the subjects, which reduces visual fatigue and brain fatigue. 15,16,13,17 Lin et al 18 found that a high colour temperature light source is more popular in the study of lighting environments for primary and secondary school students.…”

Affective evaluation of the luminous environment in university classrooms

“…One of the most significant difficulties is in conducting these type of studies in real environments. Most experiments have been carried out in laboratory environments, controlling the effect of each variable (Yan, Lee, Guan, & Liu, 2012), generally using only electric lighting, because that can be easily manipulated. Thus, these studies have examined isolated effects of lighting, such as illuminance (Durak, Camgöz Olguntürk, Yener, Güvenç, & Gürçınar, 2007), colour temperature (Park, Chang, Kim, Jeong, & Choi, 2010) or uniformity (Chraibi, Crommentuijn, Loenen, & Rosemann, 2017), providing interesting specific contributions.…”
