Abstract

In an embodiment, an attachment system for communicating light energy from a light source to a light-conducting fiber includes a light pipe body sufficiently designed to engage a distal end of a light pipe, the light pipe body comprising at least one opening configured to dissipate heat buildup from light energy; a front assembly sufficiently designed to engage the light pipe body, the front assembly comprising an orifice and at least one opening configured to dissipate heat buildup from light energy; a light-conducting fiber body sufficiently designed to engage the front assembly and to hold a proximal portion of a light-conducting fiber, the light-conducting fiber body positioned in the orifice of the front assembly; and an optical taper assembly sufficiently designed to hold an optical taper, the optical taper assembly positioned between and spaced apart from the front assembly, and positioned between and spaced apart from the light pipe.

Claims

1. An attachment system comprising:

a first portion having a cavity for holding a light pipe, the light pipe transmitting light from a light source, wherein the first portion comprises a material capable of functioning as a heat sink to dissipate heat from the system;

an optical taper sufficiently designed to alter at least one property of the light; and

a second portion having a cavity for holding a light-conducting fiber, the light-conducting fiber receiving the altered light from the optical taper,

wherein the optical taper is positioned between the first portion and the second portion and spaced apart from a distal end of the first portion, and spaced apart from a proximal end of the second portion, wherein the space between the optical taper and the first portion and the space between the optical taper and the second portion are configured to dissipate heat from the system.

2. The attachment system of claim 1, further comprising a plurality of fins in the first portion, the plurality of fins designed to conduct heat from the light pipe.

3. The attachment system of claim 2, wherein the plurality of fins are positioned at the distal end of the first portion.

4. The attachment system of claim 1, wherein the optical taper includes a reflective surface designed to reflect light towards the light source.

5. The attachment system of claim 1, wherein the second portion comprises two components that are fabricated from different materials.

6. The attachment system of claim 1, wherein the light-conducting fiber is an optical fiber.

7. The attachment system of claim 1, further comprising at least one opening in at least one of the first portion, the optical taper, or the second portion, the at least one opening configured to dissipate heat from the light energy.

8. The attachment system of claim 7, wherein the at least one opening is one of a hole, a space, a cavity or a vent.

9. The attachment system of claim 1, further comprising a space and a vent hole between a distal end of the light pipe and a proximal end of the optical taper to remove pressure buildup and minimize thermal buildup during use.

10. The attachment system of claim 1, wherein the light source comprises a light-emitting diode.

11. The attachment system of claim 1, wherein the light-conducting fiber comprises a fiber core surrounded by a cladding.

12. The device of claim 11, wherein at least a portion of the cladding is modified to alter a direction of the light.

13. A device comprising:

a light pipe body engaging a distal end of a light pipe that transmits light from a light source;

a front assembly engaging the light pipe body, the front assembly comprising an orifice;

a light-conducting fiber body engaging the front assembly and to hold a proximal portion of a light-conducting fiber, the light-conducting fiber body positioned in the orifice of the front assembly;

an optical taper positioned between and spaced apart from the front assembly; and

at least one opening in the light pipe body, the front assembly, or the light-conducting fiber body, the at least one opening configured to dissipate heat from the light source, wherein the at least one opening is one of a hole, a space, a cavity or a vent.

14. The device of claim 13, wherein the device is supplied for a single-use.

15. The device of claim 13, further comprising a plurality of fins in the light pipe body, the plurality of fins designed to conduct heat from the light pipe.

16. The device of claim 13, wherein the front assembly and the light-conducting fiber body are fabricated as one component.

17. The device of claim 13, wherein the front assembly and the light pipe body are made from a metal material.

18. The device of claim 13, wherein the light-conducting fiber is an optical fiber.

19. The device of claim 13, wherein the light-conducting fiber comprises a fiber core surrounded by a cladding.

20. The device of claim 19, wherein at least a portion of the cladding is modified to alter a direction of the light.

21. A method of using an attachment system for transmitting light energy from a light source comprising:

forming an attachment system by;

engaging a distal end of a light pipe to a light pipe body comprising at least one opening configured to dissipate heat buildup from the light energy;

engaging the light pipe body to a front assembly comprising an orifice and at least one opening configured to dissipate heat buildup from the light energy;

engaging the front assembly to a light-conducting fiber body to hold a proximal portion of a light-conducting fiber, the light-conducting fiber body positioned in the orifice of the front assembly; and

positioning an optical taper spaced apart from the front assembly and the light pipe;

engaging the light pipe to the light pipe body;

engaging the light-conducting fiber to the light-conducting fiber body;

energizing the light source to produce the light energy; and

transmitting the light energy from the light source through the light pipe and an optical taper to the light-conducting fiber.

22. The method of claim 21 further comprising programming the light source to emit a predetermined amount of energy.
