Abstract:
A diffused lighting device, comprising:a collapsible housing having a folded collapsed and an unfolded operating conditions, said housing in said unfolded operating condition defining and enclosing a three dimensional area having a first aperture at a first end thereof and a second aperture at a second end thereof, said second aperture being larger than said first aperture; a flexible diffusing member adapted to cover the second aperture when the housing is in the unfolded operating condition thereof; wherein the housing comprises a plurality of substantially rigid panels of heat resistant material, a first portion of said panels being pivotally attached at an inner edge thereof to the periphery of said first aperture, wherein at least one of said first portion of panels has at least one of a second portion of said panels being pivotally attached thereto to enable the housing to change between said folded collapsed and unfolded operating conditions, wherein the periphery of said second aperture is formed at least in part by outer edges of a plurality of said panels, said second aperture having a largest dimension defined by the greatest distance between two of said outer edges forming said second aperture when said housing is in said unfolded operating condition, wherein the dimensions of said housing in said folded collapsed condition are less than the largest dimension of said second aperture when said housing is in the unfolded operating condition and the dimensions of said first aperture are substantially the same when said housing is in the folded and unfolded conditions, and at least one of said first portion of panels may pivot independently of at least one other of said first portion of panels.
