Abstract

This paper investigates the atmosphere perception of dynamic coloured lighting over warm and cool hue ranges in a living room. Experiments were carried out with eight fully functional multi-channel tunable LED luminaires. Thirty Chinese observers (14 males and 16 females) evaluated 36 light conditions (2 luminance ×2 chroma ×3 hue range types ×3 speeds) using a questionnaire of 25 response scales. Four atmosphere factors were extracted: coziness, spaciousness, liveliness and warmth. Both dynamics and hue range significantly affected the atmosphere perception.
