Ray design and manufacturing methods
View Patent ↗A light shade can include a top surface formed by a plurality of adjacent, alternating peak and trough folds that define intervening facets, a bottom surface disposed opposite the top surface, and an edge surface transverse to and connecting the top surface and the bottom surface. The intervening facets can each be in the shape of a triangle with adjacent triangular facets sharing an edge. The shared edge can be one of a peak fold or a trough fold. One or more of the trough folds can have a plunge between the edge surface and an opposing side of the top surface. In an implementation, the light shade can be manufactured from a unitary polymeric sheet with the bottom surface being a mirror image of the top surface.
1. A light fixture assembly, comprising:
a spine;
a lighting element associated with the spine; and
a first light shade associated with the spine and at least partially covering the lighting element, the first light shade comprising:
a first surface formed by a plurality of adjacent, alternating peak and trough folds that define intervening facets;
a second surface disposed opposite the top surface;
an edge surface transverse to and connecting the first surface and the second surface; and
one or more triangular end pieces coupled to one or more of a first open end of the first light shade or an opposing second open end of the first light shade.
2. The light fixture assembly as in claim 1 , wherein the intervening facets are each in the shape of a triangle with adjacent triangular facets sharing an edge, the edge being one of a peak fold or a trough fold.
3. The light fixture assembly as in claim 2 , wherein the trough folds of the plurality of adjacent, alternating peak and trough folds disposed on a topthe first surface alternate between a positive plunge trough fold and a negative plunge trough fold.
4. The light fixture assembly as in claim 3 , wherein:
the first surface, the second surface, and the edge surface comprise a unitary polymeric sheet; and
the second surface is a mirror image of the first surface.
5. The light fixture assembly as in claim 4 , further comprising a second light shade associated with the spine, the second light shade being opposite the first light shade and being a mirror image of the first light shade.
6. The light fixture assembly as in claim 5 , wherein the intervening facets of the edge surface comprise isosceles triangles joined at a base of each triangle, the joined base forming a trough fold.
7. The light fixture assembly as in claim 1 , further comprising one or more mounting extensions connected to the spine, the one or more mounting extensions being additionally coupled to a suspension member configured to suspend the light fixture assembly.
8. The light fixture assembly as in claim 1 , further comprising:
a second light shade, the second light shade being opposite the first light shade and being a mirror image of the first light shade;
one or more additional triangular end pieces coupled to one or more of a first open end of the second light shade or an opposing second open end of the second light shade; and
one or more mounting extensions associated with the spine.
9. A method of manufacturing a light fixture, comprising:
assembling a first light shade, wherein assembling a first light shade comprises:
forming a plurality of fold lines on a unitary polymeric panel; and
folding the unitary polymeric panel along the plurality of fold lines so as to create:
a first surface;
a second surface disposed opposite the first surface;
an edge surface transverse to and connecting the first surface and the second surface;
a plurality of adjacent, alternating peaks and valleys that define intervening polygonal facets;
one or more triangular end pieces coupled to one or more of a first open end of the first light shade or an opposing second open end of the first light shade;
one or more flanges disposed at opposing ends of the unitary polymeric panel; and
coupling the one or more flanges of the first light shade to a spine, the spine being associated with a lighting element, wherein the first light shade is coupled to the spine such that the first light shade at least partially covers the lighting element.
10. The method of claim 9 , further comprising:
affixing one or more mounting extensions to the spine; and
coupling the mounting extensions to a suspension member configured to suspend the light fixture assembly.
11. The method of claim 9 , further comprising assembling a second light shade by repeating the forming and folding steps of claim 9 , and coupling the one or more flanges of the second light shade to an opposite side of the spine as the first light shade.
12. The method as in claim 11 , further comprising affixing one or more mounting extensions to the spine.
13. The method as in claim 12 , further comprising coupling the mounting extensions to a suspension member configured to suspend the light fixture assembly.
14. The method of claim 9 , further comprising mounting the light fixture on one or more of a surface or a stand.
15. The method of claim 9 , wherein the unitary polymeric panel comprises polyethylene terephthalate (PET) or polyethylene terephthalate with glycol-modification (PETG).
16. The method of claim 9 , wherein the lighting element is an LED light strip.
17. The method of claim 9 , wherein forming a plurality of fold lines on a unitary polymeric panel comprises scoring, perforating, or indenting.
18. The light fixture assembly as in claim 1 , wherein the lighting element is disposed in a hollow interior cavity.
19. The light fixture assembly as in claim 1 , wherein the lighting element is an LED light strip.
20. The light fixture assembly as in claim 4 , wherein the unitary polymeric sheet comprises polyethylene terephthalate (PET) or polyethylene terephthalate with glycol-modification (PETG).
