Abstract
A sunlight modulation device includes a light focusing module and a light deflection module. The light focusing module is configured to let incident sunlight pass through and to converge direct sunlight of the incident sunlight. The light deflection module is configured to separate the converged direct sunlight from diffusion sunlight of the incident sunlight by reflecting the converged direct sunlight. The above-mentioned sunlight modulation device allows more diverse configurations for solar panels, heating devices or the like means, as well as illumination purpose.
Claims19
A sunlight modulation device comprising:
- a light focusing module configured to let incident sunlight pass through and to converge direct sunlight of the incident sunlight;
- and
- a light deflection module configured to separate the converged direct sunlight from diffusion sunlight of the incident sunlight by reflecting the converged direct sunlight, wherein a size and/or a shape of the light deflection module is used to control amount of the diffusion sunlight passing through the light deflection module to illuminate an area underneath the light deflection module, and the converged direct sunlight reflected by the light deflection module is divergently directed to a target area.
A sunlight modulation device comprising:
- a light focusing module configured to let incident sunlight pass through and to converge direct sunlight of the incident sunlight on a focal region;
- and
- a light deflection module arranged on the focal region or adjacent to the focal region, wherein the light deflection module is configured to divergently reflect the converged direct sunlight to a target area and to control, with at least one of size and shape thereof, amount of diffusion sunlight of the incident sunlight to illuminate an area underneath the light focusing module.
