Abstract
A diffusive layer including a laminate of a plurality of transparent films is provided. At least one of the plurality of transparent films includes a plurality of diffusive elements with a concentration that is less than a percolation threshold. The plurality of diffusive elements are optical elements that diffuse light that is impinging on such element. The plurality of diffusive elements can be diffusively reflective, diffusively transmitting or combination of both. The plurality of diffusive elements can include fibers, grains, domains, and/or the like. The at least one film can also include a powder material for improving the diffusive emission of radiation and a plurality of particles that are fluorescent when exposed to radiation.
Claims20
A device, comprising:
- a set of radiation sources configured to emit radiation;
- and
- a diffusive layer located adjacent to the set of radiation sources, the diffusive layer including a plurality of transparent films, wherein at least one of the transparent films includes a plurality of diffusive elements, and wherein a concentration of the plurality of diffusive elements is below a percolation threshold.
A device, comprising:
- a set of radiation sources configured to emit radiation;
- and
- a diffusive layer located adjacent to the set of radiation sources, the diffusive layer including a plurality of transparent films, wherein at least one of the transparent films is formed of a fluoropolymer and at least one of the transparent films is formed of a fluoropolymer composite material including a fluoropolymer and a plurality of diffusive elements, and wherein a concentration of the plurality of diffusive elements is below a percolation threshold.
An enclosure, comprising:
- a plurality of radiation sources configured to emit radiation;
- a plurality of mirror elements, wherein each radiation source is located above a mirror element;
- and
- a diffusive layer located on a side of the enclosure opposite of the plurality of radiation sources, the diffusive layer including a plurality of transparent films, at least one of the transparent films includes a plurality of diffusive elements, and wherein a concentration of the plurality of diffusive elements is below a percolation threshold.
