  • Patent number: 5278738
    Abstract: A wall light fixture is disclosed which includes a hollow generally translucent bowl. The bowl has an upwardly opening recess formed therein and a reflector is mounted in the bowl within the recess. The reflector has a predetermined light reflective pattern in order to reflect light from a source contained within the reflector to reflect light upwardly relative to the frame and laterally to at least a portion of the transparent bowl so that the bowl reflects light within it to provide an entirely luminous surface on the bowl.

  • Patent number: 4799136
    Abstract: A lighting fixture adapted for uniformly illuminating a wall surface by utilizing an asymmetric light reflection pattern. The fixture includes a support housing and an elongated concave-shaped reflector which is pivotably attached to the support housing and has multiple facet surfaces arranged for reflecting light from the centrally located light source out through a front opening, which is covered with an ultraviolet filtering glass diffusion plate. The reflector has major rear and minor front reflecting portions, each portion containing multiple facet surfaces arranged in upper and lower zones with varying angles measured relative to a central vertical plane selected for reflecting light from the light source uniformly out through the diffusion plate to provide an asymmetric lighting pattern for uniformly illuminating a wall surface.

  • Patent number: 4605993
    Abstract: A battery operated lamp and battery charger are disclosed. The lamp is equipped with a rechargeable battery and a battery charger stand. The lamp has a lamp support surface with a center terminal, and a second terminal spaced from the center which engages the center terminal and second terminal respectively on the lamp. Thus the two lamp terminals will engage the two respective charge terminals regardless of the position of orientation in which the lamp is placed on the charger. The charger circuit is powered from a power cord connected to a power line through a transformer a full wave rectifier to charging lines. These diodes and a switch are connected in parallel with two diodes. The lamp battery to be charged is connected in parallel with the charging lines. Thus, with the switch closed, the charging voltage is reduced to desired value by a voltage drop caused by the resistor and the three diodes in parallel with the battery.

  • Patent number: 4383145
    Abstract: A switch having a plate like matrix with laterally spaced longitudinally extending bores extending from one end of the plate to the other and wires resting in the bores with bare parts of the wires extending through the bores and insulating parts of the wires received in notches at one end of the plate. The plate has openings in one side communicating with the bare wires so that a slider sliding on the plate engages the wires through the openings forming contact with the wires and connecting the wires together at the proper positions of the slider thereby providing a switch for electrically connecting the wires together at selected positions of the slider on the plate.

  • Patent number: 4233655
    Abstract: A spotlight having a generally cylindrical housing with an integral radially extending pistol grip handle at one end, a cord retractor in the rear and a seal beam light closing the open end of the cylindrical housing. The lamp is held in a shock absorbing position by projections on the housing and an integral trigger connected to the housing through a living hinge actuates the switch to turn the light on and off. A trigger lock holds the light "on" and the trigger guard prevents the trigger from being turned on inadvertently. An improved cord holder is provided which utilizes a pinch connection.

  • Patent number: 4218637
    Abstract: A combination floodlight, spotlight and flasher circuit is disclosed herein. The circuit is provided with a manual switch means, which will turn a spotlight to on, off, and flash, and turn the floodlight on, off, and to a battery saver position. The floodlight is operated through a unique inverter circuit and flasher circuit combination. Multiple combinations of switching modes make it possible to selectively accomplish various combinations of lights simultaneously.

  • Patent number: 4181928
    Abstract: A portable light having a U-shaped body and an elongated reflector supported on the body providing a space for batteries between the reflector and the body. Two lamps are supported on the reflector providing a flood light and a lens is supported on the body over the reflector and the lamps. Two cup-shaped end caps are supported on the ends of the light and one end cap has a frusto-conical shaped reflector integrally attached to it, and a lens closes the end of the cap having the reflector in it, and a lamp is supported on the reflector under the lens providing a spot light.

  • Patent number: 4023067
    Abstract: An inverter circuit suitable for use as a fluorescent lamp inverter ballast is disclosed. The inverter has the capability of starting the fluorescent lamp through regenerative feed-back techniques made possible by the amplification characteristic of the inverter switching transistor. Good efficiency at high frequency is provided by minimizing the transistor switching losses through use of resonant storage techniques and an unique feed-back system. Further, the normal energy lost in the feed-back circuit is eliminated by combining the resonant load means and the feed-back means into a single structure.
