Starry sky reproducing sheet and device
Abstract:
Disclosed is a starry sky reproducing sheet containing: N laminated light reducing sheets stuck together, each of which has homogeneous light reducing effects (where N is two or larger); the starry sky reproducing sheet containing, with M and L being two mutually different integers that are one or larger and N or smaller (M>L): L-layer transmission holes that are formed through L light reducing sheets stuck together, so that light beams pass therethrough; and M-layer transmission holes that are formed, through M light reducing sheets stuck together including the L light reducing sheets, at different positions from those of the L-layer transmission holes; wherein light beams incident on one face of the starry sky reproducing sheet pass through the L- and M-layer transmission holes while being attenuated at mutually different light reduction ratios to become L- and M-layer transmitted beams respectively which are visibly recognizable as transmitted-light stars having mutually different brightnesses.
