  • Patent number: 5600537
    Abstract: A means and method for rigidly elevating a structure includes a base member securable in the ground and which has a portion extending above the ground. A pole section, having a bore inside a lower end, and an upper end, can be stacked upon the base means upwardly by slip fitting the pole section onto the base end and securing it in place. A flexible, easily transportable and durable system is thereby created for elevating structures.An integrated pole for elevating light fixtures and all other necessary components such as electrical components, can be predesigned, shipped, and easily installed at a desired location. Pole top member, including rigidly secured cross arms, can be inserted on the top of a pole. All wiring for both the pole top cross arms, and the pole itself can be preconfigured and require simple connection of plugs between wiring segments.

  • Patent number: 5508882
    Abstract: A ballast case for electronic fluorescent lamp. The ballast case makes good a deficiency of potting compound even when deficient amount of potting compound is charged in the ballast enclosure, thus to facilitate the potting compound charging work and to effectively prevent generation of noise caused by overvoltage of ballast, and to effectively protect the ballast and varieties of parts. The ballast case comprises a rectangular box type ballast enclosure charged with potting compound and having the ballast and the varieties of parts therein, and a rectangular plate type cover covering the ballast enclosure. The cover has an embossed section for making good the deficiency of potting compound. The embossed section is formed by embossing an area of flat surface of the cover so that the embossed section corresponds to sizes and arrangement of the ballast and the varieties of parts.

  • Patent number: 5446617
    Abstract: A ballast circuit enclosure and grounding structure for electrically grounding a ballast circuit to a housing and for capturing transmitted RFI and EMI therefrom. The ballast circuit enclosure includes an elongate housing for receiving and surrounding the ballast circuit. End caps are attached to the housing opposite open ends in closing engagement with the housing. The end caps are fastened to the housing with fastening members extending through holes in the end caps and into elongate channels formed on the inside of the housing. The ballast circuit board rests on elongate abutment shoulders within the housing and is sandwiched between the abutment shoulders and longitudinal walls forming the elongate channels. A grounding wire on the edge of the circuit board is coupled to the ballast circuit and is in electrical contact with the fastening member and/or the channel forming elongate wall of the housing.

  • Patent number: 5428266
    Abstract: In an electronic ballast, a half-bridge inverter is powered from a constant DC voltage and provides an AC output voltage having a waveform with trapezoidally shaped half-cycles. This AC voltage is applied across the primary winding of a leakage transformer, whose loosely coupled secondary winding is connected across a gas discharge lamp. The internal inductive reactance of the secondary winding constitutes a lamp ballasting means by way of limiting the magnitude of the resulting lamp current to a pre-established desired level. The ballast is enclosed in a steel housing of conventional shape and size (i.e., rectangular: about 2.3" wide, 1.5" high, and 8.2" long). Significant power losses may result from magnetic coupling to the walls of the steel housing of the substantial leakage flux surrounding the leakage transformer.

  • Patent number: 5426347
    Abstract: A power supply is plugged into an ordinary household electrical outlet and conditionally provides a high frequency current at a power receptacle operative to receive the power plug of an ordinary table lamp; which table lamp has a special fluorescent lamp screwed into its lamp socket. Provided the special fluorescent lamp is indeed screwed into the lamp socket, and provided the lamp'switch is in its ON position, the power supply does in fact supply high frequency current from its power receptacle; which high frequency current powers the special fluorescent lamp at a nominal power level, thereby to provide for high-efficacy luminous output. A storage battery contained within the power supply is kept fully charged by current derived from the power line voltage normally present at the electrical outlet and functions such as to cause high frequency current to be supplied from the output receptacle even if the power line voltage were to be disrupted.

  • Patent number: 5371441
    Abstract: A power supply is integrally combined with a power plug, and the combination is adapted to be plugged into an ordinary household electrical outlet and operable to provide a power-line-isolated output of 120 Volt RMS at a frequency of about 30 kHz. The Volt-Ampere product available from this power supply is limited to be no more than 100 Volt-Ampere. Due to the high frequency, the electric shock hazard associated with this 120 Volt/30 kHz power supply is not higher than it is for a power supply having a voltage of only 30 Volt RMS at 60 Hz. The power supply, which also has receptacle means operable to receive and hold an ordinary electric power plug, is interposed between an ordinary household electrical outlet and the power plug of an ordinary table lamp.

  • Patent number: 5343123
    Abstract: A half-bridge inverter is powered from an ordinary electric utility power line by way of a full wave rectifier-filter means. The high frequency voltage output of the inverter is loaded with a series-combination of a tank inductor and a tank capacitor, with a fluorescent lamp being connected in parallel with the tank capacitor. The ON-time of each of the inverter's two transistors is shorter than half the period of the high frequency voltage; thereby preventing the two transistors from conducting simultaneously; thereby, in turn, protecting the inverter from self-destruction in case of lamp failure.
