Abstract: This portable lighting fixture comprises a lamp housing containing a lamp and a reflector that projects light from the lamp through an opening in the front face of the housing. A protective grill on the housing registers with the front-face opening in a location spaced from the opening. Normally located beneath the housing is a base that normally supports the housing. The grill has an outer periphery that appears rounded when viewed from a horizontal reference plane located above the housing when the housing is in its normal location atop the base. Tip-over of the fixture onto a horizontal surface that causes the central peripheral portion of the grill to fall against the horizontal surface results in the fixture rolling over in a lateral direction on the rounded grill following initial contact between the central peripheral portion of the grill and the horizontal surface.

Abstract: A passive infrared detection and conversion circuit includes a pyrosensor, a current amplifier, a capacitor, and a signal processor circuit. The signal processor is operable to charge the capacitor to a first voltage level and to measure a capacitor discharge time, the time required for the capacitor to discharge from the first voltage level to a second voltage level. The signal processor is further operable to generate an electrical control signal responsive to a variation in the capacitor discharge time which corresponds to a significant motion event. When the pyrosensor is exposed to infrared motion, it generates a transient current, and the capacitor discharge time corresponds to the transient current. The signal processor circuit includes logic operable to compare the capacitor discharge time with a long-term average capacitor discharge time.

Abstract: A fixture for portable quartz floodlights in which a plurality of clips are secured to the periphery of the housing.

Abstract: An adjustable beam light fixture with glare light shielding for illuminating a selected area without illuminating other areas. The adjustable beam light fixture has a reflector for holding a lamp and directing light from the same. The reflector is adjustably mounted on a housing. The mounting is accomplished by means of slots formed in the reflector and threaded fasteners extending outwardly from the housing and into the slots. The portion of the reflector adjacent the housing is arcuately shaped and a portion of the housing adjacent the reflector is arcuately shaped as well and with the same degree of arc. In the preferred embodiment, the housing includes means for mounting the adjustable beam light fixture on a surface.

Abstract: A lighting fixture having a new and improved sensor housing and an adjustable mast arm. The sensor housing includes a top wall, a bottom wall, a back wall having a first lead aperture for establishing electrical and mechanical connections between a proximity sensor and a source of electrical power, a transition wall, a pair of side walls, and at least one drain aperture located between the transition wall and the bottom wall. A first partition wall is located between the bottom wall and the transition wall. The first partition wall extends between the pair of side walls to form a cavity including at least one drain aperture for preventing the accumulation of water in the sensor housing. An adjustable mast arm is connected between the base and the sensor housing.

Abstract: A multimovable plastic lamp fixture. In the preferred embodiment, the lamp fixture includes a pair of lampholders for supporting a pair of floodlights or the like. Each of the lampholders are attached to a base by means of a ball and socket-type joint. The ball joint is located off-center and provides spherical positioning of the lights. A gasket located in the interior of each socket prevents moisture from entering the base and, in addition, maintains each lampholder in position due to friction. The ball and socket joint includes a knee ball cover having a semi-spherical surface for engaging the ball joint. Tabs located on the outer surface of the knee ball cover limit the rotational movement of each lampholder with respect to the base.

Abstract: An electrical circuit is provided for operating a combination insect electrocution grid and outdoor lamp. The circuit of the invention utilizes a high leakage reactance transformer in which a primary coil and two secondary coils are wound on a common core, the primary coil is centrally situated and the two secondaries are situated on opposite ends of the primary. A magnetic shunt is provided in the transformer between the primary and the high voltage secondary coil. A peaking capacitor, selected to induce the power frequency to resonate at the third harmonic, is connected to the high voltage secondary coil to generate the high voltage which energizes the electrocution grid. The other secondary coil is a ballast secondary which energizes the illumination means.

Abstract: A light fixture having a flanged upper housing, a support arm on the housing, and a reflector below the upper housing designed to dissipate heat. The reflector has an upper planar surface that fits within the flange of the upper housing. The upper planar surface has a peripheral opening extending from the edge of the upper planar surface toward the center of the upper planar surface at the side of the upper planar surface that is adjacent the support arm. An enclosure box may be placed over the peripheral opening and attached to an enclosure plate that is located at the opening of the support arm into the housing.
