摘要： An electrodeless fluorescent lamp comprises a closed-loop (“tokamak”) envelope, two ferrite cores, and an induction coil that is disposed on the envelope walls inside the closed-loop formed by the envelope. The envelope comprises two straight tubes of the same diameter. All coils' turns have essential the same length and are parallel to each other and to the closed-loop axis. Each ferrite core encircles a segment of each the coil's turn and one connecting tube. The lamp can be operated at driving frequencies of 100-600 kHz and lamp powers of 50-250 W. The ferrite core power losses were 6-8 W when the lamp was operated at a frequency of 200-300 kHz and lamp power of 140-150 W. The lamp light output was 12,500 lumen and luminous efficacy was 87 LPW.

摘要： The present invention comprises a compact electrodeless fluorescent lamp that includes a transparent envelope containing a fill of inert gas along with a vaporizable metal such as mercury. An induction coil is operated by a driver circuit, and is positioned inside of a reentrant cavity in the envelope with an adjacent permeable magnetic field manipulation structure having a shunting surface ending at a shunting surface periphery. A thermally and electrically conductive primary cooling structure is positioned adjacent the magnetic field manipulation structure to extend within the shunting surface periphery while being separated from the induction coil thereby. A further component cooling structure is provided to at least partially enclose the driver circuit connected to the induction coil.

摘要： Electron cyclotron resonance (ECR) is achieved in a source chamber of a size which is non-resonant with respect to propagation of the microwave power within the chamber. The microwaves are delivered into the chamber via a waveguide and window so that breakdown occurs initially only in a region in the vicinity of the window. A dielectric coupler between the waveguide and the window has a larger end and a smaller end and is filled with a dielectric material. The magnetic field generator for stimulation the electron resonance in the chamber includes a pair of conductive current carrying coils coaxial with each other and with an axis of the chamber, the coils being arranged in a Helmholtz configuration. The waveguide includes a microwave stub tuner for tuning the propagation and absorption of the microwave power in the plasma within the chamber to control the location and shape of the region in which the plasma is formed. A conduit provides a path for delivery of the plasma from one end of the chamber and is sized to be non-resonant with respect to propagation of the microwave energy. The magnetic field is controlled to cause the formation of the plasma with high absorption of microwave power occurring substantially within a columnar region centered on an axis of the chamber. The chamber has an insulative lining.

摘要： An electrodeless fluorescent lamp and fixture which operates at the frequency range of 50-1000 KHz and power from 20 to 200 W is disclosed. The lamp includes a bulbous envelope (1) filled with rare gas and metal vapor and a reentrant cavity (5). The inner walls of the envelope are coated with phosphor (2) and a protective coating (3). An induction coil (9), made from multiple strands of wire having very low resistance at frequencies below 1000 KHz, together with a ferrite core (10), having high permeability and low power losses, generates an inductively-coupled plasma in the envelope volume. The plasma generates visible and UV radiation that is converted into visible light by the phosphor coated on the envelope walls. A metallic cylinder (13), placed inside the ferrite core (10), removes the heat generated by the plasma from the coil and ferrite core and redirects the heat to the lamp base and thence to the lamp fixture. The power efficiency of the lamp operated at frequencies 200-300 KHz and its efficacy are the same as those in electrodeless RF lamps operated at frequencies of 2.65 MHz and at 13.56 MHz.
