  • Patent number: 5359264
    Abstract: An assembly includes an electrodeless discharge lamp disposed between a pair of field applicators, and an integral impedance matching structure for matching the impedance of the lamp and field applicators to the impedance of a power source. The structure includes a Tee junction, a transmission line including a first branch connecting a first output of the Tee junction to one of the field applicators. A second branch of the transmission line connects a second output of the Tee junction to the other field applicator. The difference between electrical lengths of the first and second branches are substantially shorter than a half-wavelength. The assembly is less complex and more compact than prior art which utilizes odd mode excitation via a half-wavelength balun transformer.

  • Patent number: 5345144
    Abstract: A press sealed lamp with an internally pressed fuse is disclosed. The filament structure is conveniently formed so the fuse links across a looped section of the initial filament structure. The loop structure provides strength to the fused filament structure prior to sealing. After the lamp is sealed, a portion of the exposed loop is trimmed, thereby limiting the electrical connection to the path through the fuse.

  • Patent number: 5325024
    Abstract: A fluorescent light source includes multiple fluorescent lamp tubes driven in parallel by a single RF source. The fluorescent lamp tubes can be twin tube fluorescent lamps or straight fluorescent lamps. RF electrical energy is capacitively coupled to low pressure discharges within each fluorescent lamp tube. External capacitive coupling electrodes can be formed at or near the ends of each fluorescent lamp tube. Alternatively, cold cathode electrodes can be located within the fluorescent lamp tubes. Ballasting of the fluorescent lamp tubes is provided by capacitive coupling between the plasma of the low pressure discharge and the electrodes, thus eliminating the need for external ballasting components.

  • Patent number: 5319529
    Abstract: An marker for an adjustment linkage for vehicle headlamp may be made from a cover holding a marker gear having an internal gearing. The cover includes a pivot point, and a snap hole that clips over a bolt head on a rotatable link. The cover is then clipped to the bolt head but can pivot the bolt head between two positions. A marker gear with an internal gear is meshed to the linkage gear, while being held by the cover. The marker may then be zeroed when in a disengaged state, and pivoted to engage the adjustment linkage and thereby register degree changes when the adjustment linkage is rotated. The adjustment linkage is designed to be operated by a Philipshead screwdriver used as a gearing. No permanent gear box is formed in the linkage. A minimal linkage is formed that is accessible from the top of the headlamp module by the length of the screw driver. The adjustment linkage is water sealed to accommodate rotation and pivoting of the linkage.

  • Patent number: 5319285
    Abstract: A starting circuit is used in combination with a high intensity discharge lamp having electrodes. An inductor is in series with the electrodes of the lamp, and a first switching transistor is arranged in series with a diode and a load resistor. The first switching transistor, diode, and resistor are arranged in shunt with the electrodes of the lamp and in series with the inductor for charging the inductor when the first switching transistor is switched ON. The energy stored in the inductor is discharged as a voltage pulse across the lamp when the first switching transistor is switched OFF. A first bias circuit turns the first switching transistor ON at a first voltage level from an AC power source. A second switching transistor turns the first transistor OFF at a second voltage level. A second bias circuit turns the second switching transistor ON at the second voltage.

  • Patent number: 5309069
    Abstract: A fluorescent lamp providing improved maintenance and brightness includes an alkaline earth halophosphate (Cool-White) phosphor, e.g. a calcium halophosphate phosphor, having a continuous protective bilayer coating of alumina surrounding silica surrounding the phosphor particles. The lamp may be a high color rendition fluorescent lamp in which a first layer of alkaline earth halophosphate phosphor coats an inner surface of the lamp envelope, and a second layer of phosphor overlies the first layer of phosphor. The second layer of phosphor is a mixture of red, blue and green emitting phosphors, at least one of these being a zinc silicate phosphor. Each of the alkaline earth halophosphate and zinc silicate phosphors have a bilayer coating in which a coating of alumina surrounds a coating of silica which surrounds the phosphor.

  • Patent number: 5309061
    Abstract: A lamp assembly includes a tubular incandescent lamp located between the four tube sections of a double twin tube compact fluorescent lamp such that heat is transferred from the incandescent lamp to the fluorescent lamp when the incandescent lamp is energized. A power source provides power to the incandescent lamp and to the fluorescent lamp through a thermal switch. The thermal switch is in thermal contact with the incandescent lamp and the fluorescent lamp. When the lamp assembly is turned on, the switch applies power to the incandescent lamp initially. When the switch is heated by the incandescent lamp to a predetermined temperature, the switch deenergizes the incandescent lamp and applies power to the fluorescent lamp.

  • Patent number: 5302134
    Abstract: An article such, as an electrical connector, for mounting upon a substrate, such as a printed circuit board. The article includes a mounting plane having locating and centering means thereon. The locating and centering means comprises first and second spaced apart, depending lugs, each of which tapers from a first diameter proximal the mounting plane to a second diameter, narrower than the first diameter, distal said mounting plane. The first lug has a longitudinal slot extending its length in a given direction and the second lug has a longitudinal slot extending its length in a direction orthogonal to the given direction. The slots extending in different directions provide a centering and holding response which fixes the connector in position so that subsequent operations may be performed.

  • Patent number: 5300860
    Abstract: A fluorescent light source includes a fluorescent lamp having first and second electrodes at or near the ends thereof for capacitive coupling of RF electrical energy to a low pressure discharge within the fluorescent lamp and an RF source having a first output lead electrically coupled to the first electrode and a second output lead electrically coupled to the second electrode. The electrodes include circuitry for inducing an RF magnetic field within the fluorescent lamp in the region of the electrodes. The RF magnetic field improves the performance of the capacitively coupled RF light source by creating an auxiliary inductive RF discharge near the capacitive coupling electrodes. The inductive discharge locally increases the plasma density and the electrode sheath capacitance and provides a reduction in RF voltage across the capacitively coupled fluorescent lamp.
