The present invention provides a lamp device comprising: a glass tube configured to cover a discharge space in which a pair of electrodes are arranged so as to face each other; and a bayonet cap portion provided in an end portion of the glass tube and electrically connected to one electrode of the pair of electrodes, wherein the bayonet cap portion is formed to have a shape including a bottom surface and a peripheral surface, and includes, in the bottom surface, a first opening configured to supply a gas to an inside of the bayonet cap portion and a second opening configured to exhaust the gas from the inside of the bayonet cap portion.

An excimer lamp includes a housing portion having a sealed internal space, an internal electrode, and a discharge gas with which the internal space is filled. One end side of the internal electrode is electrically connected to a power supply member provided with a metal foil electrically connected to the internal electrode and is sealed together with the power supply member to one end side of the housing portion via a sealing portion. The other end side of the internal electrode protrudes into the internal space. A protrusion length, being a length of the internal electrode in the internal space and a length from one end of the internal space to the other end of the internal electrode, is equal to or less than a length from the other end of the internal electrode to the other end of the internal space in a direction along the axis.

This invention is a device and method for converting a non-integrated CFL lamp from a two-bulb configuration into a one-bulb configuration.

A germicidal UV amalgam lamp with an elongated tubular lamp body and at least two filaments located on opposite ends of the lamp body. The lamp body is hermetically sealed with a pinch-sealed portion at both opposite ends, confining a gas volume in which a gas discharge can be produced along a discharge path between the filaments. Each filament has two electrical connectors, each including an internal portion connected to the filament and pinch-sealed into the lamp body. Each connector also includes an external portion located outside the lamp body for electrical connection of the lamp to a controlled power supply. The pinch-sealed portion bears a socket with an electrical temperature sensor and at least two electrical connections mounted to the socket. The at least two electrical connections of the temperature sensor are connected in parallel to the electrical connectors of the filament.

An easy-to-assemble integrated LED bulb lamp includes a lampshade, a bulb base, a lamp cap, an LED module, a driver IC, a resistor, a lampshade and a lamp cap that form a sealed cavity. The bulb base is installed to an opening of the lampshade to divide the sealed cavity into an upper compartment and a lower compartment; the LED module is installed in the upper compartment; and the LED module is partially inserted into the bulb base and connected to the driver IC in the bulb base. Since the driver IC and the LED module can be integrally fixed during the injection molding of the bulb base, therefore the actual assembling process only requires the step of soldering the solder point of the resistor, and the assembling process can be simplified significantly to increase productivity.

An adapter for connecting an LED light fixture to the threaded, screw-in socket of an Edison lamp holder. The adapter includes lever arms that toggle between a horizontal position and an inclined position. The inclined position of the lever arms poses a small outside diameter so the adapter can be inserted into the Edison socket without catching any of the socket threads. When fully seated inside the Edison socket, the lever arms are pushed into the horizontal position. A central core translating within the shell when pushed to the top position inside the shell locks the lever arms in the horizontal position. The lever arms when locked in the horizontal position define an outsider diameter larger than the internal diameter of the Edison socket to wedge the adapter therein.

A light bulb having a tapering base with a circumferential clip providing the electrical and mechanical attachment to a conventional socket. The clip includes a circumferential band and a pair of diametrically opposing spring clips that, when simultaneously pressed inward, serve to compress the circumferential band, thereby enabling removal of the light bulb from the socket.
