Applied Ergonomics, 2020
Comfortable light emitting diode (LED) lighting conditions were examined for psychological and physiological responses. Eight male and eight female subjects participated in a series of experiments. They were exposed to light emitted from LED lights of 3000 K in the ranges of 150-400 lux and 1500-5000 lux; 4000 K in the ranges of 140-640 lux and 2000 ...

Journal of Building Engineering, 2020
Abstract Lighting consumes a substantial amount of energy in buildings. Therefore, the energy can be potentially reduced by implementing optimal control strategies, including an optimal light sensor placement and an intelligent control. This paper presents a new optimal light sensor placement method (OLSPM) of a lighting system in terms of numbers ...

Comfortable Indoor Lighting Conditions Evaluated from Psychological and Physiological Responses
LEUKOS, 2015ABSTRACTComfortable indoor lighting conditions were examined for psychological and physiological responses. Ten Japanese males participated in a series of experiments. They were exposed to light emitted from fluorescent lamps of 2700 K in the range of 20–170 lux and of 1500–3000 lux, 3000 K in the range of 50–200 lux, 3500 K in the range of 100–200 lux

Indoor Comfort: Lighting Design
2020Visual perception is, of all the five senses, the one with the most immediate impact when it comes to receiving information and assessing our environment. Visual comfort, an aspect which is often overlooked in interior design, makes a very important contribution to perception of indoor comfort, along with the thermal comfort resulting from the ...

Indoor and Built Environment, 2016
The ‘hue-heat’ hypothesis states that an environment which has wavelengths predominantly toward the red end of the visual spectrum feels ‘warm’ and one with wavelengths mainly toward the blue end feels ‘cool’. In order to test the hypothesis and to study the impacts of the correlated colour temperature of a light source on thermal sensation and ...
