An Electrical Analogue in Lighting Technology

Abstract

The predetermination of the luminous flux distribution in a room is of interest in building design. The paper describes one such study carried out by the use of an electrical analogy. A twelve surface Luminous Analogue Computer designed for the purpose has been discussed. The results are found in agreement within ±5.0 percent with those obtained from digital computer. The important feature of the network representation is the separation of room geometry from the boundary conditions of surface reflectance and luminous input. It is a quick and economical method for studying the effect of a single parameter on an interior visual environment.
