Methods of manufacturing illumination systems
First Claim
1. A method of manufacturing a light panel, the method comprising:
- providing a base layer having an upper surface, a lower surface opposite the upper surface, a first end configured to receive light from a light source, and a second end opposite the first end, the upper surface including a first plurality of planar portions and a plurality of receiving spaces disposed between the first plurality of planar portions, the plurality of receiving spaces disposed at least partially between the first plurality of planar portions and the lower surface, at least one of the receiving spaces including a trapezoidal trough having first and second sidewalls, the first sidewall disposed at a first angle relative to the lower surface, and the second sidewall disposed at a second angle relative to the lower surface;
providing a cover layer having a first surface and a second surface opposite the first surface, the second surface including a second plurality of planar portions and a plurality of protrusions extending from the cover layer away from the first surface, and the second plurality of planar portions disposed at least partially between the plurality of protrusions and the first surface; and
coupling the cover layer to the base layer such that at least one of the first plurality of planar portions is positioned over at least one of the second plurality of planar portions and such that the at least one of the receiving spaces receives at least one of the plurality of protrusions to form a re-entrant turning feature between the base layer and the cover layer.

Abstract
Methods of manufacturing light panels having at least one re-entrant turning feature. In one embodiment, a method of manufacturing a light panel includes providing a base layer, providing a cover layer, and coupling the cover layer to the base layer to form at least one re-entrant turning feature between the base layer and the cover layer. In another embodiment, a method of manufacturing a light panel includes providing a base layer, forming at least one receiving space in the base layer, providing at least one prismatic block, and coupling at least a portion of the prismatic block into the receiving space such that re-entrant turning features are formed between the prismatic block and the base layer.
