摘要： An amalgam is accurately placed and retained in an optimal location near the cold spot of an electrodeless SEF lamp for operation at a mercury vapor pressure in the optimum range from approximately four to seven millitorr. The amalgam is positioned at the tip of an extended exhaust tube near the apex of the lamp envelope by forming an indentation in the exhaust tube and, in some embodiments, a dose locating member in combination therewith. An evacuation hole is formed below the indentation for evacuation of the lamp envelope, or bulb, during lamp fabrication. In an alternative embodiment, the extension of the exhaust tube is situated perpendicular to the main portion of the tube to allow for lateral adjustment of the position of the amalgam, thereby allowing for even further control of the amalgam operating temperature.

摘要： A pair of starting electrodes are provided for an electrodeless high-intensity-discharge lamp of the type having an arc tube situated within the bore of an excitation coil and in the interior of which tube is to be provided a plasma arc discharge driven by the excitation coil. Each of the starting electrodes is a conductive ring actuated by a piezoelectric bender to move from a normal rest position away from the arc tube to a starting portion disposed adjacent to an associated one of an opposed pair of envelope surfaces. A high-voltage pulse coupled between the starting electrodes causes an electric field to be produced sufficient to create a glow discharge in the arc tube, and cause an almost instantaneous transition to a high-current solenoidal discharge to form the discharge plasma responsive to the normal field provided by the excitation coil; thereafter, the benders are de-activated and the starting electrodes move back to the rest positions.

摘要： A switched AC ballast is operated synchronously with the AC line during normal running of a gas discharge lamp to limit EMI and is locked in a single phase during start-up (i.e. ignition, glow mode and warm-up) to protect the bridge switches from high voltage starting signals. Devices having a high impedance control input, such as FETs, are employed in the switching bridge thus allowing control of the upper devices in the bridge without a floating power supply. A control circuit insures proper operation of the bridge switches during all operating modes of the discharge lamp.

摘要： A closed-loop control system for a Class-D power amplifier circuit, having a variable output resonant circuit impedance, maintains high-efficiency operation by using the phase angle between the resonant load voltage and current to control tuning of the resonant circuit. The resonant load circuit voltage and current are supplied to a phase detector for detecting the phase angle therebetween and for generating a voltage proportional thereto. The output voltage from the phase detector is compared to a reference voltage by an error amplifier. The resulting error voltage is employed as the input signal to control circuitry for tuning the output resonant circuit. Such a control system is suitable for maintaining high-efficiency operation of an electrodeless high intensity discharge lamp system.

摘要： A power factor correction circuit employs a metal oxide varistor in series with a filter capacitor. The varistor provides a low-impedance path for pre-charging the filter capacitor, thus enabling the avoidance of high inrush current to circuit devices, while the filter capacitor energizes the circuit when the capacitor voltage exceeds the AC source voltage. The circuit is insensitive to normal line transients. One application is for use in a gas discharge lamp ballast.

摘要： A glass extension (24) with a cavity (32) for an amalgam (22) is added to an exhaust tube (12) or a flare (14) of a fluorescent lamp. The mouth (36) of the cavity (32) is provided with a bimetal valve having a cover portion (40) to close the cavity (32) when the lamp is cold and to open the cavity when the lamp is hot. The amalgam (22) is a metallic amalgam of, for example, mercury or other know suitable materials for establishing a metallic vapor equilibrium during operation of a discharge lamp. The amalgam holder helps to maintain optimum mercury vapor equilibrium at start-up, and to reduce the effects of mercury vapor starvation resulting from off-times.

摘要： A variable capacitor includes a fixed conductive plate and a movable conductive plate with a dielectric disposed between them. A piezoelectric actuator is used to vary the distance between the conductive plates by moving the movable plate with respect to the fixed plate, with capacitance changing in inverse proportion to distance moved. In an electrodeless high intensity discharge lamp ballast, such a variable capacitor is situated in series with the excitation coil of the lamp. When a control voltage is applied to the piezoelectric actuator, the movable plate is moved from a starting position to a running position so as to maintain the ballast load in tune under both starting and running conditions, respectively, resulting in higher efficiency operation.

摘要： A lamp ballast configuration in which input power is conducted by one circuit board to the switching devices of a half bridge circuit whose output is conducted on a second circuit board with the two circuit boards mounted parallel and spaced apart disposes the device package which extends between the two circuit boards in an exposed position for direct contact to a heat sink. Drive transformers for the switching devices are preferably mounted between the circuit boards and shielded on four of their six sides by a combination of ground planes on the circuit boards and wide, flat ground conductors connecting the ground planes of the two circuit boards. A compact, high efficiency (>91%) RF system is obtained which is suitable for excitation of an electrodeless, high-intensity-discharge lamp.

摘要： An excitation coil for an electrodeless fluorescent lamp of the type having a core of insulating material, is made of a metal having a low thermal expansion coefficient which is plated with a high-conductivity metal. An insulating coating is applied over the metal plating. An exemplary coil includes a molybdenum wire, plated with silver, and finally coated with alumina. The result is a thermally stable excitation coil that maintains its shape, even at high operating temperatures, and hence maintains its impedance characteristic over the operating range of the lamp.

摘要： A low-inductance package for multiple paralleled devices includes an electrically insulating substrate having three power terminals direct-bonded to the upper surface thereof and a conductive pad direct-bonded to the lower surface thereof for connection to a heat sink. Two groups of multiple parallel-coupled devices are each soldered to one of the three power terminals and are further connected in a half-bridge configuration such that one of the three power terminals is common to both groups of devices. The package further includes a pair of first Kelvin terminals, i.e., a first Kelvin control terminal and a first Kelvin source terminal, and a pair of second Kelvin terminals, i.e., a second Kelvin control terminal and a second Kelvin source terminal. The Kelvin terminals are soldered to the appropriate power terminals, depending upon the particular circuit configuration. The multiple parallel-coupled devices of each group are aligned such that the lengths of the wire bonds to the respective control and power terminals are substantially the same and furthermore are shortened. As a result, the stray inductance due to the wire bonds is the same for each group of devices and is minimized. Current sharing and simultaneous switching of devices within each group are thus ensured.
