## Abstract

In one aspect, a light module is disclosed, which includes a housing providing a hollow chamber extending from a proximal end to a distal end, and a lens positioned in the hollow chamber, where the lens has a lens body comprising an input surface for receiving light from a light source and an output surface through which light exits the lens body, said lens further comprising a collar at least partially encircling said lens body. The light module further includes at least one shoulder on which the lens collar can be seated for positioning the lens within the housing. A light source, e.g., an LED, is coupled to the hollow chamber, e.g., at its proximal end, for providing light to the lens.

## Claims

### Claim 1

A light module, comprising:
a housing providing a hollow chamber extending from a proximal end to a distal end,
a lens positioned in the hollow chamber, the lens having a lens body comprising an input surface for receiving light from a light source and an output surface through which light exits the lens,
a pair of sleeves disposed on opposite sides of the lens,
an adapter configured for removable and replaceable coupling to the distal end of the hollow chamber of the housing, the adapter being further configured for receiving a proximal part of a light guide such that the light guide is secured within the adapter so as to receive at least a portion of the light exiting the output surface of the lens.

### Claim 2 (depends on 1)

The light module of claim 1, further wherein said adapter comprises an opening on a lateral surface thereof for receiving a retaining pin for securing the light guide within the adapter.

### Claim 3 (depends on 1)

The light module of claim 1, wherein said adapter comprises a housing having a plurality of external threads for engaging with a plurality of internal threads disposed at an end of said hollow chamber for coupling the adapter to the hollow chamber.

### Claim 4 (depends on 1)

The light module of claim 1, wherein said hollow chamber is substantially cylindrical.

### Claim 5 (depends on 1)

The light module of claim 1, wherein said light guide comprises an optical fiber.

### Claim 6 (depends on 1)

The light module of claim 1, wherein said light guide comprises a bundle of optical fibers.

### Claim 7 (depends on 1)

The light module of claim 1, wherein said light module comprises a retaining window.

### Claim 8 (depends on 7)

The light module of claim 7, wherein said retaining window comprises a plurality of internal threads for engaging with said external threads of said hollow chamber for coupling the adapter to said hollow chamber.
