A gas discharge tube lighting assembly includes a discharge tube collar, a discharge tube having a stem assembly with a first portion fitting within the discharge tube and a second portion having a seal ring with a diameter greater than the discharge tube outer diameter, the collar and tube connected by adhesive-less mechanical forces exerted on the upper, lower, and first and second flexible clamps with the discharge tube located partially in the aperture.

Abstract: The invention is a THz waveguide source (3) having a core (9) of great nonlinear coefficient and of a great absorption. The source (3) is adapted to behave as a waveguide in pumping and also in THz range. The THz waveguide source (3) has a cladding of smaller absorption coefficient in the THz range than that of the core. The solution according to the invention diminishes the influence of absorption, while enhances efficiency of generating THz radiation. The waveguide structure and the tilted pulse front excitation together results a greater interaction length and thus a greater THz generating efficiency. According to the solution of the invention highly efficient compact THz waveguide sources can be realized.

Abstract: This compact fluorescent lamp includes a discharge tube arrangement with at least one discharge tube formed of glass and enclosing a discharge volume filled with a discharge gas. A ballast circuit is connected to the electrodes disposed at each end of a continuous arc path for controlling the current in the tube. A substantially spherical portion of an outer envelope encloses the tube arrangement and an elongated end portion encloses the ballast circuit. The end portion of the outer envelope is closed and sealed by a seal formed of the same material as the material of the outer envelope. In the associated method of manufacture, the envelope is separated by cutting along a circumferential line into an upper part and a lower part, the ballast circuit introduced into the lower part and respective lead-in wires and the lead-out wires are short and need not be insulated. The ballast circuit and the discharge tube arrangement are held and supported in the outer envelope by the connecting wires and fixing means.

Abstract: The compact fluorescent lamp comprises a bulb shaped outer envelope enclosing a discharge tube having a coiled configuration and a ballast unit for controlling the current in the tube. The lamp further comprises at least one joint mechanical support and starting aid means for positioning the discharge tube and the ballast unit and reducing a breakdown voltage path of the discharge tube. The at least one mechanical support and starting aid means is made of an electrically conducting material and connected electrically to at least one of the electrodes. The neck portion has a retaining member, and the mechanical support and starting aid means is supported by the retaining member and clamped on the discharge tube at least at a location in a vicinity of a middle section of the arc path. The mechanical support means further comprises at least one support section to provide support against an apex of the outer envelope, and at least one fixing section for fixing of the discharge tube.

Abstract: A lamp assembly provides both instant light through use of an incandescent/halogen lamp source and an energy saving type light provided by a compact fluorescent lamp source. Both light sources are fixed within the assembly by a fixing mechanism that spaces the lights sources from each other such that heat from one source does not negatively affect the second light source or any other portion of the assembly.

Abstract: An LED light bulb that includes a base providing an electrical connector and a substantially hollow envelope extending from the base. The light bulb further includes a metal space separator having a top side, bottom side and side wall that has a plurality of holes connected by at least one channel that extends through the interior of the separator, such that air can pass through the separator. At least one LED is mounted on the separator in electrical connection with the base connector.

Abstract: A compact fluorescent lamp includes an inverted compact fluorescent light source housed within an outer envelope. Locating the first and second ends of the coiled CFL source positions the electrodes within a substantially spherical outer envelope at a location remotely spaced from the ballast compartment. In this manner, only small diameter first and second lead wires that mechanically and electrically engage the electrodes pass through small dimensioned passages in a separation member in the outer envelope cavity. This substantially reduces the thermal stress on the components.
