Abstract
A flashlight has a pair of light emitting elements mounted on a pivotable switch actuator to place the light emitting elements in any one of an OFF position, a spot illumination position, and a flood illumination position.
Claims10
A flashlight capable of spot illumination or flood illumination selectively, comprising:
- a switch mechanism having a moveable switch actuator with electrical contacts thereon cooperable selectively with fixed electrical contacts and having a pair of light emitting elements thereon connected to respective electrical contacts thereon,
- wherein the switch actuator is moveable among three positions, namely an OFF position in which neither light-emitting element is lit, a spot illumination position in which only one of the light emitting elements is lit, and a flood illumination position in which both of the light emitting elements are lit.
A flashlight comprising:
- a case having a barrel for receiving batteries therein and a head attached to an end of the barrel and having a reflector therein;
- a switch mechanism having fixed electrical contacts mounted in the case and having moveable electrical contacts mounted on a switch actuator that is pivotably supported in the case and that has a finger-engaging portion extending through a slot in the head;
- and
- a pair of light emitting elements mounted on the actuator and pivotable therewith,
- wherein the reflector has an arcuate slot through which the light emitting elements are exposed and along which the light emitting elements are moved as the switch actuator is pivoted,
- wherein each of the light emitting elements is connected to a corresponding moveable contact for lighting that light emitting element when its moveable contact engages a fixed contact, and
- wherein the switch actuator has three selectable positions, namely an OFF position in which neither light emitting device is lit, a spot-illumination position in which one of the light emitting elements is centered on the reflector and is lit, and a flood illumination position in which the light emitting elements are disposed at opposite sides of the center of the reflector and both are lit.
