In order to determine user acceptance for light-emitting diode (LED) office lighting, a full-scale experiment was conducted in two mock-up office rooms with different light spectra at two different illuminances. Six LED spectra and two fluorescent lamp spectra were used for the study. There were four spectra (three LED spectra and one fluorescent lamp spectrum) at a correlated colour temperature (CCT) of 4000 K and four spectra (three LED spectra and one fluorescent lamp spectrum) at a CCT of…

Effects of Correlated Colour Temperature of LED Light on Visual Sensation, Perception, and Cognitive Performance in a Classroom Lighting Environment

Illuminance levels have been standardized and regulated for many purposes. However, the effects of correlated colour temperature of lighting have received little attention in the field. This study

A Randomized Controlled Trail for Comparing LED Color Temperature and Color Rendering Attributes in Different Illuminance Environments for Human-Centric Office Lighting

The findings are that LEDs with lower CRI values at warm color temperatures and LEDs with higher CRIvalues at cool temperatures provide the right level of color attributes for office lighting.

Effect of correlated colour temperature and illuminance levels on user’s visual perception under LED lighting in Taiwan

The effects of various correlated colour temperature and illuminance level combinations on visual perception by using LED lighting were evaluated to identify lighting combinations that can respond to different psychological needs and can be used as a guide in the future design of lighting equipment.

LED lighting system for better color rendition space: the effect of color rendering index
