Abstract: A combination lamp and flashlight assembly including a frame; a headlamp attachment and a charging attachment carried by the frame; a cable electrically coupling the headlamp attachment and the charging attachment; a headlamp head; and a battery pack, wherein the assembly is changeable between a headlamp configuration, where the headlamp head is mechanically and electrically coupled to the headlamp attachment and the battery pack is mechanically and electrically coupled to the charging attachment, and a handheld flashlight configuration, where the headlamp head is mechanically and electrically coupled to the battery pack to form a handheld flashlight. The assembly is also changeable to a cycle lamp configuration, where the headlamp head is mechanically and electrically coupled to a headlamp attachment of a handle bar mount to form a cycle lamp and the battery pack is mechanically and electrically coupled to a charging attachment of a cycle tube mount.

Abstract: A combination reflector and LED conversion module for a non-LED flashlight includes a cup-shaped reflector including an interior with a reflective surface, an exterior, an open end, and an end opposite the open end; and one or more LEDs carried by the cup-shaped reflector adjacent the end opposite the open end. The combination reflector and LED conversion module replaces an existing non-LED bulb and reflector of a non-LED flashlight to convert the non-LED flashlight to a LED flashlight.

Abstract: A charging system includes a charging cap having a cradle with first and second electrodes; and a rechargeable unit including a charging end having third and fourth electrodes arranged for engagement by the first and second electrode of the charging cap when the rechargeable unit is received in the charging cap and thereby provide electrical contact to enable charging of the rechargeable unit. At least one recess in the rechargeable unit is arranged to receive one or more clamping members of the charging cap for releasably securing the rechargeable unit to the charging cap.

Abstract: A twist push light focusing system for a flashlight includes a focus member movable in a longitudinal direction of the flashlight; a light source; a focus lens; and a rotational-to-longitudinal movement translation mechanism operably coupled to the focus member and at least one of the light source and the focus lens to translate longitudinal movement of the focus member into rotational movement in the rotational-to-longitudinal movement translation mechanism and relative longitudinal movement between the light source and the focus lens to achieve focus.

Abstract: An adapter lens includes an inner converging lens part; a convex light output region; a front conical light output region; an outer reflector part; a rearwardly open blind hole defining surface including a flat base surface and a frustoconical side surface that together define a light incidence region and a frustoconical hole having an inner end diameter, an outer end diameter, and allowing for longitudinal movement therein of a LED light source along an optical axis of the adapter lens within the frustoconical hole for changing a light cone emitted from the adapter lens. The adapter lens has a height H and a maximum diameter MD, and the ratio of the height H to the maximum diameter MD is greater than 0.5.
