Light sources are available in a variety of spectral power distributions (SPDs) and this affects spatial brightness in a manner not predicted by quantities such as illuminance. Tuning light source SPD to better match the sensitivity of visual perception may allow the same spatial brightness but at lower illuminance with potential reductions in energy consumption. Consideration of experimental design was used to review 70 studies of spatial brightness. Of these, the 19 studies considered to… Expand

Lamp spectrum and spatial brightness at photopic levels: Investigating prediction using S/P ratio and gamut area
An experiment was carried out to investigate spatial brightness at photopic levels under lighting of different spectral power distributions. One aim was to replicate the experiment reported in 1990Expand
Spectral tuning of LED sources for improved lighting quality
Placement of radiant power at different wavelengths within the visible spectrum affects our visual perceptions, such as color perception, brightness perception, and whiteness perception. In recentExpand

This paper presents a pilot study that has investigated the suitability of mean room surface exitance as a predictor of spatial brightness and compared these results with how horizontal illuminanceExpand
Perceptual responses to LED illumination with colour rendering indices of 85 and 97
It is concluded that the colour and whiteness rendition must be considered on a par with luminous efficacy in perceptual responses under illumination from two sources. Expand
Spatial and temporal aspects of visual performance in relation to light level and normal aging
The research contained in this thesis describes three studies designed to investigate the ability of the observer to detect stimuli defined by changes in luminance in space and/or time in mesopicExpand

The results showed that the boundary illuminances estimated from psychological and physiological responses did not significantly differ between male and female subjects, but differed markedly from those of fluorescent lights tested in a previous study. Expand
Judging the Scientific Quality of Applied Lighting Research
ABSTRACT Applied lighting research is inherently interdisciplinary. Any one study in which investigators seek to understand the effects of light may involve expertise drawn from fields as varied asExpand
Occupant response to different correlated colour temperatures of white LED lighting
Abstract Correlated Colour Temperature (CCT) of lighting may affect not only occupant visual perception, but also other indoor environment perceptions, such as perceptions of the thermal environmentExpand
Comfortable Indoor Lighting Conditions Evaluated from Psychological and Physiological Responses
ABSTRACT Comfortable indoor lighting conditions were examined for psychological and physiological responses. Ten Japanese males participated in a series of experiments. They were exposed to lightExpand


White light brightness–luminance relationship
Brightness perception of near-white surfaces is influenced by the spectral power distribution (SPD) of the illuminant; at the same time, this has an effect on task performance, either directly or viaExpand
Toward a model of outdoor lighting scene brightness
Light quantities based on the photopic luminous efficiency function do not predict brightness perceptions of lighted outdoor scenes such as streets, parking lots and plazas. This paper summarises aExpand
Perception of electric light sources of different colour properties
An analysis of the experimental conditions by which V(λ) was determined suggests that it cannot account fully for the human response to light. Much experimental work has shown a discrepancy betweenExpand
Tuning the Fluorescent Spectrum for the Trichromatic Visual Response: A Pilot Study
Abstract Results of a pilot study are presented that explored the hypotheses that brightness and color perception would be enhanced by increasing the proportion of spectral content within theExpand
Lighting in offices: lamp spectrum and brightness
Evidence is presented which suggests that the brightness of a space may be maintained, despite a reduction in illuminance, through the choice of lamp spectral power distribution. Expand
Influence of Field Size on the Spectral Sensitivity of the Eye in the Photopic and Mesopic Range
The V10°(&lgr;) curve derived from color equation measurements could be confirmed as a luminance efficiency curve obtained by direct brightness match measurements and could be shown to nearly coincide with those obtained with the 64° field. Expand
Photopic luminance does not always predict perceived room brightness
The perception of room brightness over photopic luminances ranging from 30 cd m-2 to 67 cd m-2 was judged by 12 subjects in an almost uniformly white experimental chamber. Two different illuminantsExpand
The impact of spectral power distribution on the performance of an achromatic visual task
This experiment tests the hypothesis that light sources that produce smaller pupil sizes ensure better achromatic visual task performance at the same photopic illuminance. Two groups of subjects, oneExpand
