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.

Abstract: A lighting device (10) has a light source, a light pipe (28), two convex magnifying lenses (40, 60), and an adjusting mechanism (20) for moving the two magnifying lenses (40, 60) relative to the light source. The light emitted from the light source is dispersed and directed into the light pipe (28) by a reflector (26). The light pipe (28) transfers collimated light through the first (40) and second (60) magnifier lenses which redirects the light to produce a circular spotlight beam having uniform intensity. The size of the spotlight beam is adjusted by an adjusting mechanism (20).
