A dielectric barrier discharge lamp assembly for a fluid treatment system. The lamp assembly can include an inductive secondary, first and second electrodes coupled to the inductive secondary, and a lamp including a dielectric barrier interposed between the first and second electrodes. The dielectric barrier can define a discharge chamber including a discharge gas, and one of the first and second electrodes can extend within the discharge chamber. The inductive secondary can be adapted to receive power from a nearby inductive primary to promote a dielectric barrier discharge in the discharge chamber. The resulting dielectric barrier discharge can generate ultraviolet light for the treatment of air or water, or for other applications.

A push-in or quick-connect light bulb provides for at least one spring-loaded metal tabs built into the bulb's base that are configured to retract when a user pushes the light bulb into a light socket, thereby allowing an electrical connection to be made between the light bulb's base and the light socket. In some embodiments, the one or more metal tabs, the bulb's base, or both the metal tab(s) and the bulb's base are configured to conduct electricity from the socket to the present invention's filament or other illumination element.

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

Interfaces for electrical (e.g., lighting) devices involve use of electrically conductive edge contacts arranged on or protruding from edges of printed circuit boards (PCBs) that provide or facilitate electrical connections to first and second externally accessible electrical contacts, such as may include threaded and foot contacts of a lighting device including a screw-shaped male base. First and/or second edge contacts of a PCB may protrude through first and second openings in a housing to form first and second externally accessible contact, or directly engage first and second externally accessible contact elements associated with (e.g., retained by) the housing. A contact element retained by a housing may define a slot in the interior of the housing to directly engage an edge contact of the PCB. Electric power is supplied to the PCB via edge contacts without need for intervening wires or soldered connections.

According to an aspect there is provided a base for an electric lamp. The base includes a tubular enclosure extending along an axial direction between a first and a second end portion of the enclosure, an insulator attached to the first end portion of the enclosure. The insulator has an inner portion facing towards an inner space of the enclosure, an outer portion facing away from said inner space and at least one channel for receiving a contact pin, the channel extending from the outer portion, through the insulator and leading into said inner space. The base also includes a housing for accommodating electrical circuitry for operating the electric lamp. The housing is attached to the inner portion of the insulator such that a rotation of the housing relative to the insulator about the axial direction is prevented, and a rotation of the housing relative to the enclosure is prevented.
