Patent number: 7102298Abstract: An integrated lamp/lamp electronics unit includes a lamp having a first end with first end electrical terminals, and a second end with second end electrical terminals. An end cap having an interior section is placed into electrical connection with the first end electrical terminals at the first end of the lamp. Lamp electronics are configured to control operation of the lamp and are connected only to the second end electrical terminals. The lamp electronics are carried on a circuit board having a configuration substantially matching the second end of the lamp portion. The circuit board is placed within the interior of a lamp electronics end cap, and the end cap is attached in a permanent relationship to the second end of the lamp.Type: GrantFiled: August 5, 2002Date of Patent: September 5, 2006Assignee: General Electric CompanyInventors: Louis R. Nerone, David J. Kachmarik, Joseph C. Oberle, Michael S. Idelchik

Patent number: 6794827Abstract: A plurality of lighting ballasts (12, 14, 16) draw power from a single DC bus signal. A power factor correction circuit (10) rectifies and smoothes AC power to produce the DC bus signal. In order to prevent damage to the ballast (12) when a lamp (18) dies or is removed, the ballast (12) includes an AC switch that senses damaging conditions and responds by changing a resonant frequency of the ballast (12). The AC switch operates in 2-3 second cycles. While it is operative, it shunts current away from inductors (38, 40) of the ballast (12) causing a resonant frequency of the ballast (12) to change. At the end of the cycle, the switch turns off, but if a load fault is still present in the ballast (12) it activates again. Preferably, the AC switch has a response time of approximately 500 &mgr;s.Type: GrantFiled: September 19, 2002Date of Patent: September 21, 2004Assignee: General Electric CompanyInventors: Louis R. Nerone, Joseph C. Oberle

Patent number: 6555965Abstract: A fluorescent lamp assembly that has a planar configuration with an open area defined within the lamp tube. A low profile, integral common housing encloses a ballast and a portion of the lamp structure within the open area of the lamp tube. The housing mechanically secures the lamp tube and contains an electrical connector allow the lamp electronics to plug into an electrical main. The electronics and the lamp are contained in a common structure so they can be used, handled, and discarded as a single unit.Type: GrantFiled: October 19, 2000Date of Patent: April 29, 2003Assignee: General Electric CompanyInventor: Joseph C.

Patent number: 5412280Abstract: Disclosed is an electrodeless, low pressure gas discharge lamp. The lamp includes a vitreous envelope containing a metal vapor and an inert gas. The envelope is shaped with an external chamber for receiving an electrical excitation circuit. The excitation circuit is effective for exciting the metal vapor to emit light with electromagnetic fields that are passed through the vitreous envelope from outside, to inside, the envelope. A circuit supplies electrical power from power mains to the excitation circuit. A transparent, electrically conductive coating is disposed on the inner surface of the vitreous envelope for suppressing electromagnetic interference on the power mains. An electrically conductive coating is disposed on the outer surface of the vitreous envelope; it is capacitively coupled to the inner conductive coating, via a wall of the vitreous envelope, and is maintained at a suitable potential for suppressing electromagnetic interference on the power mains.Type: GrantFiled: April 18, 1994Date of Patent: May 2, 1995Assignee: General Electric CompanyInventors: Curtis E. Scott, Vito J. Arsena, Spiro Vamvakas, Joseph C. Oberle

Patent number: 5394062Abstract: A gas discharge lamp ballast with an indicator of operability of the ballast is disclosed. The ballast circuit comprises circuitry for providing a d.c. bus voltage on a bus conductor with respect to a ground, and a resonant load circuit. The resonant load circuit includes lamp terminals for connecting to a removable gas discharge lamp, a resonant inductor, and a resonant capacitor. The resonant inductor and resonant capacitor are selected to set a magnitude, and resonant frequency, of a bidirectional current in the lamp. Further included is a converter circuitry, including first and second serially connected switches coupled between the bus conductor and the ground, and providing to the resonant load circuit, at a node coupled between the first and second switches, a voltage that alternates between first and second voltage levels.Type: GrantFiled: December 15, 1993Date of Patent: February 28, 1995Assignee: General Electric CompanyInventors: Michael M.
