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.

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.

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.

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.

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.

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.
