A film illumination system including: a. a flexible sheet of translucent material having a thickness up to 0,5 mm, wherein the sheet is sufficiently flexible that it can be rolled upon itself with a radius of curvature of less than 50 times the thickness of the sheet, the sheet having: a bounding edge; a folded portion wherein the sheet is folded upon itself such that portions of the bounding edge overlap, wherein the overlapping portions of the bounding edge are at least substantially aligned to define an at least substantially smooth and continuous surface; and an unfolded portion wherein the sheet is not folded upon itself; wherein a number of discrete legs extend from the unfolded portion, and wherein the legs each terminate at the portions of the bounding edge which overlap to define input areas at which light may be input from a light source, wherein the legs are folded between their bounding edges and the unfolded portion at folds such that the legs are bent into stacked relationship, wherein each fold in the sheets redirects a leg at an angle, wherein where the sheet is folded, the folds are such that they have a radius of curvature of 75 times the thickness of the film or less b. a light source adjacent the overlapping portions of the bounding edge, the light source being coupled to the light input area and comprising a plurality of light emitting diodes, each light emitting diode emitting light of a different color, such as red, blue and green, wherein the light from the light emitting diodes is mixed within the legs to appear as light of a color different from the colors emitted by the light emitting diodes. a. a flexible sheet of translucent material having a thickness up to 0,5 mm, wherein the sheet is sufficiently flexible that it can be rolled upon itself with a radius of curvature of less than 50 times the thickness of the sheet, the sheet having: a bounding edge; a folded portion wherein the sheet is folded upon itself such that portions of the bounding edge overlap, wherein the overlapping portions of the bounding edge are at least substantially aligned to define an at least substantially smooth and continuous surface; and an unfolded portion wherein the sheet is not folded upon itself; wherein a number of discrete legs extend from the unfolded portion, and wherein the legs each terminate at the portions of the bounding edge which overlap to define input areas at which light may be input from a light source, wherein the legs are folded between their bounding edges and the unfolded portion at folds such that the legs are bent into stacked relationship, wherein each fold in the sheets redirects a leg at an angle, wherein where the sheet is folded, the folds are such that they have a radius of curvature of 75 times the thickness of the film or less a bounding edge; a folded portion wherein the sheet is folded upon itself such that portions of the bounding edge overlap, wherein the overlapping portions of the bounding edge are at least substantially aligned to define an at least substantially smooth and continuous surface; and an unfolded portion wherein the sheet is not folded upon itself; b. a light source adjacent the overlapping portions of the bounding edge, the light source being coupled to the light input area and comprising a plurality of light emitting diodes, each light emitting diode emitting light of a different color, such as red, blue and green, wherein the light from the light emitting diodes is mixed within the legs to appear as light of a color different from the colors emitted by the light emitting diodes.
