发明名称 Collapsible light diffusing device and diffused lighting apparatus
摘要 A collapsible light diffusing device includes a collapsible housing having a folded and an unfolded condition. The housing in the unfolded condition defines a first aperture and a second aperture, the second aperture being larger than the first aperture. The housing is adapted to be mounted to a light source such that the first aperture is nearer to the light source than the second aperture. The device further includes a flexible light diffusing member adapted to cover the second aperture when the housing is in the unfolded condition. The housing includes a plurality of substantially rigid panels of heat resistant material, hinged together to enable the housing to be manipulated between the folded and unfolded conditions.
