Abstract

According to various embodiments, a method for manufacturing a lens may be provided. The method may include: determining a NURBS (non-uniform rational basis spline) representation of a provisional lens geometry; simulating ray trajectories in a lens with the provisional lens geometry based on the NURBS representation; determining a final lens geometry based on the simulated ray trajectories; and producing a lens with the final lens geometry.

First claim

What is claimed is:

1. An illuminating device comprising
a light source configured to emit light;
a light guiding member having a proximal end and a distal end opposite the proximal end, wherein the light source is disposed at about the proximal end of the light guiding member, wherein the light guiding member is designed to allow light emitted from the light source to enter the light guiding member at the proximal end and exit the light guiding member at the distal end; and
a proximal anchoring member connected to the light guiding member at about the proximal end;
wherein the proximal anchoring member includes an eye.

2. The illuminating device of claim 1 , further comprising:
a distal anchoring member for a display to anchor on, the distal anchoring member designed to be connected to the light guiding member at about the distal end, wherein light exiting from the light guiding member is configured to illuminate the display.

3. The illuminating device of claim 2 , further comprising a distal end cap having a connecting portion and an anchoring portion opposite the connecting portion, the connecting portion designed to connect the distal end cap to the light guiding member at about the distal end and the anchoring portion comprises the distal anchoring member.

4. The illuminating device of claim 3 ,
wherein the distal end cap is configured to diffuse light.

5. The illuminating device of claim 1 , further comprising a proximal end cap having a connecting portion and an anchoring portion opposite the connecting portion, the connecting portion designed to connect the proximal end cap to the light guiding member at about the proximal end, the anchoring portion comprises the proximal anchoring member, and wherein the light source is disposed within the proximal end cap.

6. The illuminating device of claim 3 , further comprising a reinforcing structure extending from a proximal end cap to the distal end cap.

7. The illuminating device of claim 6 , wherein the reinforcing structure includes a cylindrical sleeve surrounding the light guiding member, wherein the reinforcing structure comprises a proximal engaging end and a distal engaging end, wherein the proximal engaging end is designed to engage the proximal end cap and the distal engaging end is designed to engage the distal end cap.

8. The illuminating device of claim 2 , wherein the light guiding member is elongated and extends from about the light source to about the distal anchoring member.

9. The illuminating device of claim 1 , wherein the light guiding member includes a tube.

10. The illuminating device of claim 1 , further comprising a refractive element disposed between the light source and the light guiding member, wherein light emitted from the light source passes through the refractive element before entering the light guiding member at the proximal end.

11. The illuminating device of claim 10 , wherein the refractive element comprises at least one lens.

12. The illuminating device of claim 6 , wherein the light guiding element comprises an aligning member at about the proximal end of the light guiding element, the aligning member designed to be coupled to the reinforcing structure for aligning the light guiding element along the longitudinal axis of the cylindrical sleeve.

13. The illuminating device of claim 2 , wherein the distal anchoring member includes an eye for hanging the display.

14. The illuminating device of claim 1 , wherein the light guiding member is tapered such that the width at about the proximal end is wider than the width at the distal end of the light guiding member.

15. The illuminating device of claim 1 , further comprising at least one lens.

16. A method for manufacturing an illuminating device, the method comprising
providing a light source configured to emit light;
providing a light guiding member having a proximal end and a distal end opposite the proximal end, wherein the light source is disposed at about the proximal end of the light guiding member, wherein the light guiding member is designed to allow light emitted from the light source to enter the light guiding member at the proximal end and exit the light guiding member at the distal end; and
a proximal anchoring member connected to the light guiding member at about the proximal end;
wherein the proximal anchoring member includes an eye.
