Abstract
A solar concentrator having a concentrator element for collecting input light, a redirecting component with a plurality of incremental steps for receiving the light and also for redirecting the light, and a waveguide including a plurality of incremental portions enabling collection and concentration of the light onto a receiver. Other systems replace the receiver by a light source so system optics can provide illumination.
Claims1
A solar concentrator, comprising:
- a concentrator element for collecting input light;
- a redirecting component having a plurality of incremental steps receiving the input light and redirecting the light;
- and
- a waveguide having a geometry coupled to the plurality of incremental steps along a length, the waveguide propagating the input light for collection by a receiver and wherein the receiver width is a function of height of the waveguide.
