Abstract: A light tunnel (10), to be used for close inspection of items (24) therein, includes a framework (12) comprised of an outer structure (30) and inner assembly (34) which support sheets of material (64) to define a pair of opposed side walls (16) and (18) and an arched top wall (20). An inner surface (42) of said walls being highly reflective to direct the light rays emanating form a light source (46) from the walls to the item to be inspected.

Abstract: A method and apparatus for applying ceiling panels to a light tunnel is provided. The applicator hereof includes a gantry, a frame, and a shifter for vertically shifting said frame relative to said gantry. The frame is presents a pair of generally arcuate spaced-apart rails each having a pair of terminal feet, with a bridge interconnecting the feet. The gantry includes a plurality of towers each having a pair of upright tower legs. The tower legs are attached to a base and preferably further supported by braces to maintain an upright configuration. A shifter is provided to operatively interconnect the gantry and the frame for raising the latter and the panel placed thereon into juxtaposition with a framework of the light tunnel. In accordance with the method, the applicator is placed within the framework of the light tunnel, a panel is placed on the platform, and the platform is shifted to place the panel in position for attachment to the framework.
