Patent ID: 7618154

Claim:
A reconfigurable illumination device comprising: an elongated housing having a proximal end, a distal end, and defining a cavity therebetween, the cavity open at the proximal end and configured to receive a portable power source; a light source assembly configured for positioning at least partially within the cavity of the elongated housing; an interchangeable light guide also configured for positioning at least partially within the cavity of the elongated housing; and a heat sink module in thermal communication with the light source, the heat sink module being secured at one end to an interior surface of the cavity, and removably secured at another end to the interchangeable light guide, the interchangeable light guide being removably coupled to the elongated housing by the heat sink module, the interchangeable light guide also being disposed with respect to the light source assembly to guide at least a portion of light from the light source, wherein the interchangeable light guide is removably coupled to the elongated housing by the heat sink module via a first thread on the heat sink module adapted to engage a first mating thread on the interchangeable light guide, and wherein the heat sink module is secured to the interior surface of the cavity via a second thread on the interior surface of the cavity adapted to engage a second mating thread on the heat sink module.
