Abstract

An illumination device includes a strip of light propagating material and a plurality of lighting units arranged behind a back surface of the light propagating material, and a controller for controlling the operation of the plurality of lighting unit. The illumination device is positioned in a gap defined between at least two reflective surfaces, such that light from the lighting units projects out of the light propagating material visually from the gap between the two reflective surfaces.

First claim

The invention claimed is:

1. A reflective display comprising:
at least two reflective surfaces defining a gap therebetween;
a strip of light propagating material, the strip of light propagating material defining a front surface, two side surfaces and a back surface, the side surfaces being adapted for positioning between the two reflective surfaces and the front surface;
a plurality of lighting units positioned along the back surface of the strip of light propagating material for propagating light in the strip of light propagating material, whereby light propagated in the light propagating material visually suppresses the gap between the two reflective surfaces; and
a plurality of light detectors, the light detectors being positioned along the strip of light propagating material, each light detector collecting light projected on the reflective surfaces in an area surrounding the light detector and generating corresponding lighting data.

2. The reflective display of claim 1 , wherein the lightning units are positioned along the back of the strip of light propagating material at equal distances from one another.

3. The reflective display of claim 1 , wherein the strip of light propagating material is flexible.

4. The reflective display of claim 1 , wherein the strip of light propagating material is compressible.

5. The reflective display of claim 1 , wherein the strip of light propagating material is flexible and compressible.

6. The reflective display of claim 1 , wherein the strip of light propagating material is made of one of the following: a clear material, a semi-clear material or a semi-opaque material.

7. The reflective display of claim 1 , wherein the strip of lighting propagating material is made of a light scattering material.

8. The reflective display of claim 1 , wherein the at least two reflective surfaces consist of any of the following: sheets of mirrors, Mylar sheets mounted on frames.

9. The reflective display of claim 1 , further comprising a support structure for securing the plurality of lighting units.

10. The reflective display of claim 9 , wherein the support structure allows the light propagating material to be inserted and compressed between the adjacent reflective surfaces.

11. The reflective display of claim 10 , wherein the support structure allows the adjacent reflective surfaces to move with respect to one another.

12. The reflective display of claim 1 , wherein each lighting unit comprises: a red light-emitting diode (LED), a green LED and a blue LED.

13. The reflective display of claim 12 , wherein each lighting unit further comprises a light controller for controlling actuation of the red LED, the green LED and the blue LED.

14. The reflective display of claim 13 , wherein the light controller receives the lighting data of at least one of the light detectors and controls the red LED, the green LED and the blue LED based on the lighting data.

15. The reflective display of claim 13 , wherein the light controller receives the lighting data from an image generator and controls the red LED, the green LED and the blue LED based on the lighting data received from the image generator.

16. The reflective display of claim 15 , wherein the light controller receives the lighting data from the image generator wirelessly.
