Light modifying elements

A curved light modifying element configured to modify light from a light source located in proximity to an inner portion of the curved light modifying element, the curved light modifying element comprising:

• one or more optical film pieces characterized by:
• a central light emitting portion;
• and
• one or more edge trusses disposed at two opposing edges of at least one of the one or more optical film pieces, the one or more edge trusses characterized by one or more folds of at least a portion of at least one of the one or more optical film pieces, the one or more edge trusses disposed at the two opposing edges are further characterized to support the two opposing edges of the at least one of the one or more optical film pieces in a substantially planar configuration;
• and
• wherein the central light emitting portion is configured into a curved shape by laterally moving the two opposing edges of at least one of the one or more optical film pieces towards each other.

A light modifying element comprising:

• one or more optical film pieces characterized by:
• one or more edge trusses disposed on each edge of at least one of the one or more optical film pieces, the one or more edge trusses characterized by one or more folds of at least a portion of at least one of the one or more optical film pieces, the one or more edge trusses disposed at each edge are further characterized to support the one or more optical film pieces in a substantially planar configuration;
• and
• the one or more optical film pieces are further configured to form a hollow truncated pyramid shape characterized by four sloping sides, a planar base and a planar top, wherein the plane of the planar top is substantially parallel to the plane of the planar base, and wherein the perimeter of the planar top is smaller than the perimeter of the planar base.
