Abstract
A solar light concentration plate comprises a plurality of holograms diffracting incident light wherein each of the plurality of the holograms has a thickness, at least one intermediate light guide plate disposed between the plurality of the holograms, and a pair of external light guide plates disposed on outer surfaces of outermost holograms of the plurality of the holograms, wherein at least one of the pair of the external light guide plates has an inner surface and an outer surface inclined relative to the inner surface.
Claims20
A solar light concentration plate comprising:
- a plurality of holograms diffracting incident light wherein the plurality of the holograms have different thicknesses;
- wherein the plurality of the holograms comprises a first hologram and a second hologram, and the second hologram has a larger thickness and smaller wavelength selectively than the first hologram;
- at least one intermediate light guide plate disposed between the plurality of the holograms;
- and
- a pair of external light guide plates disposed on outer surfaces of outermost holograms of the plurality of the holograms,
- wherein at least one of the pair of the external light guide plates has an inner surface, and an outer surface inclined relative to the inner surface.
A method of guiding light using a solar light concentration plate, the method comprising;
- providing a plurality of holograms diffracting incident light wherein the plurality of the holograms have different thicknesses;
- wherein the plurality of the holograms comprises a first hologram and a second hologram, and the second hologram has a larger thickness and smaller wavelength selectively than the first hologram;
- disposing at least one intermediate light guide plate between the plurality of the holograms;
- and
- disposing a pair of external light guide plates on outer surfaces of outermost holograms of the plurality of the holograms,
- wherein at least one of the pair of the external light guide plates has an inner surface and an outer surface inclined relative to the inner surface.
