Light concentrator structures and methods

摘要

An arrangement utilizes diffractive, reflective and/or refractive optical elements combined to intensify and homogenize electromagnetic energy, such as natural sunlight in the terrestrial environment, for purposes such as irradiating a target area with concentrated homogenized energy. A heat activated safety mechanism is also described.

主权项

1. An arrangement comprising:
at least one optical member configured to receive electromagnetic energy incident thereon during normal operational temperatures; and at least one diffractive member, the diffractive member comprising a plurality of diffractive elements, the diffractive elements constructed and configured to diffract and homogenize the incident electromagnetic energy, wherein the at least one diffractive member is configured to concentrate the incident electromagnetic energy into a highly eccentric ellipse which approximates a line.
