SHADING SYSTEM USING LIQUID LENS AND LIGHT WAVEGUIDE

摘要

Techniques described herein relate to assemblies with selective optical transmissivity. The assembly can include a first layer and a second layer. The first layer can include a multiple number of liquid lens units. The liquid lens units can be configured to selectively focus incoming optical rays between a first focal length and a second focal length. The second layer can be spaced apart from the first layer and can include a multiple number of optical waveguides. The optical waveguides can include one or more waveguide inlets such that the second layer includes a multiple number of waveguide inlets. Each of the waveguide inlets may be associated with a respective one of the liquid lens units and may be spaced apart from the respective one of the liquid lens units by a distance within the focal range. Assemblies defined herein particularly useful in modifying the natural lighting of an interior space.
