Kind Code:
A1
Abstract:
Light tunnels, methods for forming a light tunnel, and apparatuses including light tunnels are disclosed herein. A light tunnel includes a plurality of reflectors cooperatively engaging with one another by a series of notches therein. The inner edges of the reflectors are chamfered to improve ease of assembly and decrease chipping of the edges during assembly. An adhesive can be applied at junctions between the reflectors on their outer surfaces. This construction eliminates or retards light leakage and adhesive leakage.
