    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: An electrodeless low-pressure discharge lamp (10) according to the invention is provided with a radiation-transmitting discharge vessel (11) which encloses a discharge space (14) containing an ionizable filling in a gastight manner. The lamp (10) is in addition provided with a first and a second winding (20, 23) for conducting a high-frequency current during operation. The first winding (20) extends along a longitudinal axis (29) in a cavity (28) surrounded by the discharge vessel (11). The second winding (23) is arranged along the longitudinal axis (29) in the extended direction of the first winding (20) outside the cavity (18) surrounded by the discharge vessel (11). During operation, the currents in the first and second windings (20, 23) have the same tangential direction relative to the longitudinal axis (29). The lamp causes comparatively little magnetic interference, while it is avoided that the second winding (23) hampers lamp ignition or causes an unstable lamp operation.

    Abstract: A first portion of a spiral wire support for an amalgam is securely fitted into an exhaust tube formed in a re-entrant cavity of an electrodeless fluorescent lamp before attachment and sealing of the re-entrant cavity to the bulb of the lamp. A second portion of the spiral wire support extends into the bulb and holds an amalgam in thermal contact with the apex of the bulb. The second portion has a larger diameter than the first portion to ensure against movement of the spiral wire support into the exhaust tube. The end of the second portion of the spiral wire support is wetted with an alloy capable of forming an amalgam with mercury prior to insertion of the wire support into the exhaust tube. Mercury is added to the bulb after final evacuation of the bulb in preparation for dosing the lamp with its fill. As a result, an amalgam is formed and maintained in thermal contact with the apex of the bulb, regardless of lamp orientation.

    Abstract: An electrodeless discharge lamp comprising an arc tube constructed of a light-transmissive material. An exciting structure surrounds the arc tube and is energizable with radio frequency current to develop an arc discharge. A reflective coating of non-conducting insulating material is disposed on the arc tube wall and is located to reflect light from the arc discharge through the arc tube. The reflective coating and the uncoated portion of the arc tube wall are surrounded by the exciting structure so that light from the arc discharge may reach the reflective coating without blockage by the exciting structure and, following reflection by the coating, travel through the uncoated portion of the arc tube wall.

An inductive device is disposed in the cavity for generating a high-frequency electric field inside the discharge vessel during lamp operation. The inductive device includes a winding of metal wire surrounding a cylindrical core of magnetizable material. A cooling body is in contact with the cylindrical core for removing heat generated in the core during lamp operation. The cooling body is closed in a gastight manner and includes a condenser, an evaporator, a liquid, and a capillary structure (T, U) which comprises a winding (U) of gauze surrounding a vapor channel (V) for transporting the liquid from the condenser to the evaporator. The capillary structure has a central partition wall (T), which divides the vapor channel in two, and is connected along two opposing longitudinal sides thereof to the gauze winding (U). The cooling body has very good cooling properties, so that the electrodeless low-pressure discharge lamp has a high luminous efficacy.

    Abstract: 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.
