摘要： A high power source unit employing a piezoelectric transformer detects whether the output of the piezoelectric transformer reaches a predetermined value or not using a comparator. Subsequently, using a frequency scanning circuit, an oscillation frequency of a driving frequency control circuit is scanned across a resonance frequency of the piezoelectric transformer. During this frequency scanning, the efficiency of the piezoelectric transformer is detected by a efficiency calculating circuit to detect the frequency where the efficiency becomes maximum, by a most efficient frequency detecting circuit. By maintaining this frequency, the piezoelectric transformer may operate at the frequency at optimal efficiency.

摘要： An electrical assembly for selectively supplying either 120 volts or 227 volts from a junction box to a high intensity discharge lamp fixture via a dual voltage ballast and a dual voltage electrical connector. The dual voltage electrical connector has dual operation capacity with input voltages of either 120 or 277 volts. The connector comprises a female connector having nine bores extending therethrough with female terminals fixedly coupled within four of the bores, and a male connector having nine bores extending therethrough with contact pins extending outwardly from four of these bores. When the connectors are coupled together in their first orientation, the male contact pin which conducts 120 volts of electricity engages the female terminal connected to a line wire. When the male and female connectors are manually rotated 180.degree. relative to one another into their second orientation, a different pin, which conducts 277 volts, engages the line wire terminal. A latching device is fixedly coupled to the two connectors for releasably coupling the two connectors together.

摘要： Fluorescent type lamps are arranged to have high frequency power derived from standard, commercial A.C. sources either directly or from power levels distributed from a master ballast. When the master ballast is employed, it functions as an interface between the primary power source and a distribution network to one or more modules so as to relieve the modules of operations such as initial power form conversions, filtering and power factors correcting which require large components. The module or modules driven by the master ballast output are contained within the lamp envelope or attached as an extension of the lamp envelope. The module is formed of elements mounted as a miniaturized unit configured to fit within the lamp envelope or to attach to the end of the envelope. The module includes oscillator components mounted on an envelope board so as to form an assembly with a cross-section compatible with the perimeter of the envelope itself. The module can operate independent of a master ballast unit by including power handling circuitry within the module.

摘要： A ballast stabilization arrangement is provided for minimizing or eliminating lamp current oscillation, or moding, of gas discharge lamps, such as fluorescent lamps, and a method for carrying out this arrangement is described. This is carried out by adding a frequency response zero to the current circuitry in a ballast. An example of this circuitry includes a feedback network where a sensed lamp current signal is compared with a reference signal by an error amplifier having a resistance placed in series with its feedback capacitance to implement the zero in the frequency response of the control circuit.

摘要： A variable inductor includes at most one coil of electrically conductive material and at most two distinct, separately formed portions of magnetic core material positioned to conduct magnetic flux resulting from passage of electrical current through the coil. At least one of the portions of magnetic core material is located at least partially within a space surrounded by the coil and is movable with respect to the coil. A control device is attached to the movable portion of magnetic core material in a manner such that the movable portion can be moved in its entirety, by manipulating the control device, to change the configuration of a gap within the space surrounded by the coil and defined in part by the movable portion, to vary thereby the inductance of the coil.

摘要： An electrodeless high intensity discharge (HID) lamp system includes a ballast housing constructed from a thermally conductive material for containing a ballast of a type having at least one RF power switching device. The RF switching device is thermally coupled to the ballast housing to provide heat sinking therefor. The excitation coil of the HID lamp is also thermally coupled to said ballast housing via thermally-conductive coil mounting studs, but is electrically insulated therefrom. An opening in the ballast housing enables the electrical connection of the coil to the output circuit of the ballast. The RF power switching device and the excitation coil are arranged so as to be spaced apart sufficiently in order to maintain the ballast housing temperature substantially uniform during operation of said lamp, thereby maximizing lamp efficiency and increasing the useful life of the lamp and ballast.

摘要： A ballast for an electrodeless high intensity discharge lamp comprises a Class-D power amplifier including an integrated tuning capacitor network and heat sink. A series blocking/tuning capacitor and a parallel tuning capacitor are integrated by sharing a common capacitor plate. The metal plates of the parallel tuning capacitor also comprise heat sink planes to remove excess heat from the excitation coil of the lamp. Heat sink fins are affixed to the plates of the parallel capacitor. Efficiency is maximized by matching the impedance of the ballast load network.

摘要： All the magnetic functions required in a ballast for a fluorescent lamp are integrated in a single, standard magnetic core which provides isolation, voltage step-up, ballasting, power factor correction and cathode heat for multiple lamps operating multiple lamps in an isolated-series configuration. In a three-legged transformer core embodiment, the primary winding is continuously wound on all three legs, while secondary windings are included on two of the legs. Ballasting inductance is provided by winding the primary on the third leg. The number of primary turns N.sub.p necessary to avoid saturation of the transformer for any specific input voltage and core material, the number of primary windings N.sub.p1 on the secondary legs and the number of primary windings N.sub.p2 on the third leg are determined according to the equation 2N.sub.p1 =N.sub.p -N.sub.p2.
