The tubular envelope is formed of soft glass and has a fluorescent phosphor coating disposed on the inner surfaces. Electrodes (14) with external electrical contacts are disposed at each end of the envelope. A ballast (12) is disposed within the bulbous envelope. The ballast is electrically connected to the lamp (15), whereby to control current in the fluorescent lamp. A heat shield (17) is disposed between the lamp and the ballast to thermally isolate the lamp from the ballast, whereby heat from the lamp will not adversely affect the ballast.

    Abstract: An integrally molded flat fluorescent lamp comprising a convoluted channel member (11) formed of vitreous glass with convoluted channel (14) fabricated by employing a combination of vacuum-assisted sag molding, press molding and blow molding techniques. While the part (11) is molten, a planar member (13) is fused to it by pressing the parts (11 and 13 at 15) together to form a closed glass envelope. The inside of the envelope is coated with a phosphor layer and preferably the external surface of the envelope is coated with a reflective layer. A pair of electron-emissive electrodes are fused to openings (12) in the envelope. They are sealed through glass flares at the two holes integral to the envelope. The envelope is evacuated and filled with a rare gas and mercury to a suitable pressure and sealed off to form a lamp.

    Abstract: An electrodeless fluorescent lamp and fixture is disclosed which operates at radio frequencies and contains a bifilar coil to reduce RF voltage between the plasma and the coil and a metallic cylinder (10) to remove heat from a said bifilar coil. The bifilar coil consists of two windings. The primary (induction) winding (6) is used to generate RF electrical azimuthal field in the bulb volume needed to maintain the inductively-coupled RF plasma. The second (bifilar) winding (18) has essentially the same number of turns and is wound on the inductive winding (6), but in the direction opposite to that of the primary (inductive) winding. The RF current flowing in the inductive winding (6) induces an RF voltage of the opposite polarity in the bifilar winding (18), so two adjacent turns of both windings have equal (or nearly equal) but of opposite sign RF potentials with respect to the plasma. This results in the mutual "cancellation" of capacitive RF electric fields induced by both windings in the plasma and in a sheath formed between the plasma and the cavity walls. The reduction of the electric field in turn results in the lowering of a direct current voltage across the sheath thereby lowering the energy of ions which are accelerated in this sheath coating. The lowering of ion energy reduces the damage caused by ions and leads to improved maintenance and a longer life lamp.

    Abstract: This invention is about a CMH lamp arc tube seal construction where the feedthrough electrode contains a cermet in such a manner that the said cermet is either not exposed outside the ceramic capillary (which in most cases is polycrystalline alumina, PCA) or if it is exposed to the outside of the arc tube, the part that is exposed has no current carrying function. The invention provides safe ways of assembling the cermet so as to avoid breakage of the said cermet due to mechanical stresses in the electrical connections.

    Abstract: An arc discharge metal halide lamp having a discharge chamber having visible light permeable walls bounding a discharge region supported electrodes in a discharge region spaced apart by a distance Le with an average interior diameter equal to D so they have a selected ratio with D exceeding a minimum value. Ionizable materials are provided in this chamber involving a noble gas, one or more halides, and mercury in an amount sufficiently small so as to result in a relatively low maximum voltage drop between the electrodes during lamp operation for a lamp dissipation sufficient to have the chamber wall loading exceed a minimum value or so as to maintain chamber luminosity above a minimum value for a selected operational duration.
