Patent number: 5566047Abstract: Disclosed is an AC electrical apparatus including a vibrating device and a mounting structure supporting the device. In the improvement, a resilient insulator is interposed between the device and the mounting structure so that vibrations are isolated from the mounting structure. In a highly preferred embodiment, the insulator has a disc-like component between a standoff spacer and the mounting structure. Another such component is between the mounting structure and the head of the bolt which attaching the device to the structure. And a tube-like component of the insulator is between the bolt and such structure.Type: GrantFiled: June 5, 1995Date of Patent: October 15, 1996Assignee: Ruud Lighting, Inc.Inventors: Michael J. Kahn, Donald Wandler

Patent number: 5510762Abstract: A leadless type ballast transformer having a connector at one end of the housing for accepting a mating connector which supplies voltage to the ballast and provides the operating voltage to the lamps controlled by the ballast. Uninsulated connection leads extending inwardly of the housing from the connector terminals to contact the lugs of a terminal board adjacent a transformer coil with the magnet wires of the transformer coils also being in contact with the terminal board lugs. The connection leads and magnet wires are permanently electrically connected to the terminal board lugs by ultrasonic welding.Type: GrantFiled: April 12, 1994Date of Patent: April 23, 1996Assignee: Magnetek, Inc.Inventors: Steve M. Carey, James H. Ball, Raymond H. VanWagener

Patent number: 5508882Abstract: 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.Type: GrantFiled: September 19, 1994Date of Patent: April 16, 1996Assignee: Toe il Media Co., Ltd.Inventor: Hyung J.

Patent number: 5446617Abstract: 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.Type: GrantFiled: May 13, 1994Date of Patent: August 29, 1995Assignee: Diversitec IncorporatedInventors: Troy E. Blocher, Daniel P. O'Brien

Patent number: 5428266Abstract: 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.Type: GrantFiled: July 22, 1991Date of Patent: June 27, 1995Inventor: Ole K. Nilssen

Patent number: 5426347Abstract: 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.Type: GrantFiled: March 31, 1994Date of Patent: June 20, 1995Inventor: Ole K. Nilssen

Patent number: 5382876Abstract: A cord connection structure for connecting a ballast circuit and a starter circuit in which an output cord from a starter circuit unit mounted on a lamp body is connected to a discharge bulb inserted into a bulb insertion hole, and an output cord from a ballast circuit unit disposed in the vicinity of a starter circuit unit is removably connected through a connector to a connector connection part (receptacle) provided in the starter circuit unit, characterized in that a connector slip-off preventing protector covering the connector coupled into the connector connection part is provided around the connector connection part (receptacle). Such a construction makes it difficult for a general user to connect and disconnect the connector of high voltage to and from the connector connection part.Type: GrantFiled: August 3, 1992Date of Patent: January 17, 1995Assignee: Koito Manufacturing Co., Ltd.Inventors: Masatoshi Sugasawa, Atsushi Toda, Masaru Sasaki, Masayasu Yamashita, Akihiro Matsumoto, Akiyoshi Ozaki, Goichi Oda

Patent number: 5371441Abstract: 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.Type: GrantFiled: May 2, 1994Date of Patent: December 6, 1994Inventor: Ole K.
