LED light source
A LED light source includes a longitudinally extending light guide having a longitudinally extending light emitting face having a length, a first end face and a longitudinally spaced apart second end face. A LED light source is provided at least at the first end face. The light emitting face has a plurality of light emitting locations provided thereon. The density of the light emitting locations increases from the first end face towards the second end face.
1. A frame for a work of art comprises at least one side panel extending around a perimeter and defining an inner opening in which the work of art is displayable, the at least one side panel comprising a longitudinally extending light guide having a longitudinally extending light emitting face that faces inwards towards another portion of the at least one side panel, the longitudinally extending light emitting face having a length, a first end face and a longitudinally spaced apart second end face and an LED light source is provided at least at the first end face, wherein the light emitting face has a plurality of light emitting locations provided thereon, wherein the density of the light emitting locations increases from the first end face towards the second end face.
2. The frame of claim 1 wherein the fame is in the shape of a parallelogram and comprises four side panels, each of which comprises a longitudinally extending light guide having a light emitting face that faces onwards.
3. The frame of claim 2 wherein each light emitting face has an inner side positioned proximate a plane in which the work of art seats when mounted in the frame and a spaced apart outer side and the inner side is position forward of the plane.
4. The frame of claim 1 wherein the light emitting face has an inner side positioned proximate a plane in which the work of art seats when mounted in the frame and a spaced apart outer side and the inner side is position forward of the plane.
5. The frame of claim 1 wherein a first LED light source is provided at the first end face and a second LED light source is provided at the second end face wherein the density of the light emitting locations increases from each of the first end face and the second end face to a middle of the light emitting face.
6. The frame of claim 1 wherein the LED light source is provided only at the first end face wherein the density of the light emitting locations increases from the first end face to the second end face.
