1. A portable lighting device, comprising:
- a body having a central axis;
a light source coupled to the body, the light source configured to emit a beam of light along the central axis;
a head assembly rotatably coupled to the body along the central axis, the head assembly comprising a ring gear coupled to the head assembly along the central axis; and
a filter assembly rotatably coupled to the body and having a rotational axis offset from the central axis, the filter assembly comprising a plurality of filters and a pinion gear interlocked with the ring gear;
wherein rotation of the head assembly rotates the ring gear, thereby rotating the pinion gear to selectively align different filters of the plurality of filters along the central axis on an output side of the light source.

Abstract
The present invention relates to a portable lighting device comprising a body, a light source coupled to the body and configured to emit a beam of light along a central axis, a head assembly rotatably coupled to the body, and a filter assembly rotatably coupled to the body. The filter assembly has a rotational axis and a plurality of filters offset from the central axis. Rotation of the head assembly rotates the filter assembly to align different filters of the plurality of filters along the central axis on an output side of the light source.
