Title: Nonimaging radiant energy direction device

Abstract

A nonimaging radiant energy light direction device is provided which may be utilized for both the collection and transmission of radiant energy. The device includes an energy transducer and at least one reflective wall of particular contour. The particular contour is determined by assuming the transducer is acting as an incoherent Lambertian radiant energy emitter of finite dimension. The reflective wall is placed along a flow line of the geometrical vector flux associated with such an emitter. The ideal contour will also satisfy the condition that the rays of radiant energy are in a state of detailed balance along the mirror. Both trough shaped and cone like direction devices can be developed from this design method.
