Abstract The present paper deals with the influence of light shelf and model reflectance on light shelf performance. The variation with the day of the year of the mean hourly illuminance values measured at 0.50 m . from a south facing side window in 1 : 10 models has been studied for hours with unit sunshine fraction σ. The four light shelves

Linear lighting systems for shelf and cove lighting
SPIE Proceedings, 2005LED tapes are emerging as cost effective light sources for longitudinal applications, such as strip lighting and accent lighting on buildings, and shelf and cove lighting for interior lighting. Such applications can be sorted into direct viewing and illuminative.

Light shelf performance in Madrid, Spain
Building and Environment, 1997Abstract The performance of a light shelf with a reflectance of about 91% after excluding the specular component (reflectance about 1%), providing for solar protection during the long, hot, dry summer season, is studied in Madrid (40.4°N, 4.4°W) using two scale models (1:10) with rectangular openings facing south, one taken as a reference and the ...
