Abstract
A raidant energy nonimaging light direction device is provided. The device includes an energy transducer and a reflective wall whose contour is particularly determined with respect to the geometrical vector flux of a field associated with the transducer.
Claims14
A device for directing and transducing energy comprising:
- an energy transducer, a first reflective wall of a particular contour, which contour coincides with nonlinear lines of flow of geometrical vector flux of a virtual radiant energy emitter of finite dimension radiating according to Lambert's law within a restricted angle not greater than 90 degrees were said virtual emitter positioned to coincide with said transducer.
A device for collecting radiant energy from a source, comprising:
- an energy absorber of particular contour, a first reflective wall of a particular contour coinciding with a non-linear line of flow of the geometrical vector flux of a virtual radiant energy emitter, were said absorber positioned between said virtual emitter and said source.
