Underground mines are completely dependent on artificial lighting systems to provide adequate illumination for safe and productive work. As a result the U.S. Bureau of Mines has developed a computer model to assist lighting and equipment manufacturers in optimizing the selection and placement of luminaires on large underground equipment. This paper describes a new model for predicting the illumination provided by various luminaires. This model has shown to have several benefits over a previous model which calculated illumination using the Inverse Square Law. These benefits include: (1) greater accuracy (particularly at close distances), (2) the model considers the influence of reflected light, (3) the method can be used to evaluate multiple light sources, and (4) it eliminates the need to assume that the luminaire is a point source of light.
