ABSTRACT
A luminaire is a mirror deflecting the light from a source to a receiver, so as to obtain on the receiver a prescribed light distribution. If the light source is large, it is then necessary to use anidolic optics to obtain the shape of the luminaire’s mirrors. The calculation of a luminaire that produces a uniform illumination on a plane is simplified if the plane is considered to be at a large distance from the luminaire. A luminaire for uniform light distribution on a line placed at an infinite distance must then produce an angular intensity distribution for the light. In the case of linear sources, the intensity produced by the luminaire is given by expression. The method of design for the luminaires with partial involutes is similar to the one described for linear sources. It is, however, necessary to remember that the light source has a different geometry, so the equations must adapt to this new situation.
