  • Patent number: 4755916
    Abstract: A light is provided which includes a first, forwardly concave reflector member, a first, forward lamp spaced ahead of the reflector member, and a second rearwardly concave reflector member spaced forward of the lamp. The rear reflector member has a generally parabolic surface and the forward member has a generally arcuate surface. When the lamp is activated, its rays generally travel forward, are reflected off the second reflector member rearward onto the first reflector member, and thence forward in a substantially parallel array to provide a spot light. A second lamp is located axially rearward of the first lamp and forward of the first reflector. When this lamp is activated, its rays travel generally laterally, strike the first reflector member, and thence are reflected forward in generally random array to provide a flood light. Means are provided to selectively activate either or both of said lamps.

  • Patent number: 4586117
    Abstract: A portable light including at least one lamp bulb, a battery and a control circuit for conducting electrical current from the battery to the lamp bulb comprising in combination:an airflow passageway in which said battery, said control circuit, and said lamp bulb are serially mounted, said airflow passage defined at one end by an inlet in airflow communication with the atmosphere and defined at another end by an outlet in airflow communication with the atmosphere, and means for moving air between the inlet and outlet along said air passageway mounted in said air passageway and actuated by said control circuit.

  • Patent number: 4502103
    Abstract: A lamp bulb mount for axially mounting two lamp bulbs into a light for selective operation in relation to a combination flood and spot light is disclosed. The mount includes a forward base and a rearward base selectively connectable to each other. The forward base is conformable to a reflector member of the light and has an opening formed therein which receives the lamp bulbs supported by the rear base. Interconnection of the forward and rearward base and placement of the forward base against the reflector member projects the light bulbs through the reflector member in a predetermined relationship. A socket of each base of the mount is convertible between flanged lamp bulbs and twin pin lamp bulbs through alternative spring mountings. A carrying case for the mount includes a fan adapted to maintain air flow throughout the light, cooling the battery, control circuitry and lamp bulbs.
