Lighting design methods for obstructed interiors Commission Internationale de L'Eclairage / 01-Jan-2004 / 32 pages ISBN: 9783901906329 Traditional lighting calculation methods assume a clear room volume allowance for the influence of room contents. Objects located between light source and task will act to block direct light and will result in some light being absorbed by the object and some reflected from its surface. This may cause both local and general reductions in planar illuminance...
