Patent abstract
A portable lighting device, such as a flashlight, having a rotatable band disposed around the exterior of the flashlight is disclosed. Rotational movement of the band is converted to lateral movement of the light emitting element within the flashlight. The structural integrity of the flashlight is not compromised when the rotatable band is rotated around the flashlight to adjust the width of the projected pattern of light.
