Self-tracking solar concentrator

摘要

A system for capturing solar light of the sun, whereby the solar light comprises a short wavelength light component and a long wavelength light component. The system comprises at least a lens (101), a light-guide (102), and a self-adaptive coupling feature (103). The at least one lens is arranged adjacent to the light-guide in order to focus the long wavelength component onto the self-adaptive coupling feature, and the self-adaptive coupling feature is configured to couple the short wavelength light component into the light-guide.

1. A system for capturing solar light of the sun, whereby the solar light comprises a short wavelength light component and a long wavelength light component, the system comprising:
at least a lens, a light-guide, and a self-adaptive coupling feature, whereby the at least one lens is arranged adjacent to the light-guide in order to focus the long wavelength component onto the self-adaptive coupling feature, and the self-adaptive coupling feature is configured to couple the short wavelength light component into the light-guide,wherein the self-adaptive coupling feature comprises
a mechanical actuator that is configured to be thermally induced by absorbing the long wavelength light component and to be reversible, a transparent elastomer, and at least a reflecting prism, whereby the mechanical actuator and the transparent elastomer are arranged such that the mechanical actuator when thermally induced presses the trasnsparent elastometer against the light guide to induce the at least one prism to couple the short wavelength light component into the light guide.
