ABSTRACT:
A light reflecting and shielding module for a suspended ceiling or the like is disclosed. The module is enabled to be shipped or stored in flattened condition and is comprised of a pair of planar rail members with at least one baffle member hingedly connected thereto and extending transversely thereof. Upon erection of the rail members to parallel spaced relationship, the centroid of the mass of the baffle is spaced from the axis of hinge means connecting same to the rail members, so that upon erection of the rail members the mass centroid of the baffle causes same to hang pendently from the spaced and parallel rail members.
