Abstract

Luminous ceilings were developed in the 1940’s from a comprehensive mathematical study of the integral equations for the interflection of light in rooms. It was found that criteria for optimum vision are satisfied for most visual tasks and most shapes of rooms if the entire ceiling is the source of light and room reflectances are sufficiently high. In the 1950’s criteria for lamp spacing above the luminous panels were developed and many undecorated luminous ceilings were installed. To make the optimum luminous environment more attractive and interesting, hand-painted luminous ceilings were developed in the 1960’s and 1970’s and applied to homes, offices and classrooms. This paper presents the criteria for creating computer generated narrative luminous ceilings and gives practical examples applied to classroom lighting.
