Abstract: A flashlight unit includes a housing having an opening including a lens and a light source located in the housing for emitting light through the lens in a lighting direction. The light source is movable in the lighting direction, relative to the lens, for adjusting light emission. The flashlight unit has an adjusting mechanism including a rotatable member for adjusting the position of the light source in the lighting direction, relative to the lens. There is also a limiter for limiting rotational movement of the rotatable member when the light source reaches a predetermined position.

Abstract: A portable lighting device includes a main unit, rechargeable battery cells housed in the main unit, and a lighting unit including a light source and a solar panel. The lighting unit is attached to the main unit and is supported by the main unit for movement between a first position situated close to the main unit and exposing the light source for illumination and a second position extending from the main unit and exposing the solar panel for recharging the battery cells.
