Abstract: An illumination/ventilation system is described wherein the light tube used to support one or more incandescent lamps forms part of the ventilation system itself. The system includes a blower having a forced air outlet with first a conduit connectings the outlet of the blower to an inlet of the light tube. A second conduit connects to an outlet of the light tube to form a circulating air path through which air is forced by the blower to ventilate the light tube. Preferably, the light tube comprises an elongate base member and an elongate light diffuser for supporting the lamps along the light tube. The light tube also includes an elongate track member having a tongue along its entire length which mates which a groove along the length of the base member to secure the track in the base member. Each of the individual lamps is supported in the elongate track member by an adapter track clip which is press-fitted, rather than twisted, into the track.

Abstract: The assembly has a low-pressure sodium discharge lamp (1), of which the outer envelope (4) has an electrically conducting coating (5), which is connected through a capacitor (29) to one of the current supply conductors (13) to the light source (3) of the lamp (1) and to the neutral conductor (18) of the power supply (2), which supplies an alternating voltage having a frequency of at least 80 kHz. The lamp holder (23) has an eccentrically arranged projection at its inner surface while the lamp cap (6) has an eccentrically arranged recess at its outer surface, which, when the lamp cap (6) is arranged in the lamp holder (23), engage with each other and guarantee a connection of the capacitor (29) to the neutral conductor (18). The lamp (1) is suitable for operation at mains voltage frequency and is still fitting into the lamp holder of mains voltage frequency equipment.

Abstract: A mounting arrangement for use with a baseless electrical lamp includes an insulating fixture having a plurality of electrically conductive terminal members. The exposed lead wires which protrude from the press of the baseless electrical lamp engage the electrically conductive terminal members so as to both provide electrical current to the baseless electrical lamp and retain the baseless electrical lamp in the insulating fixture.

Abstract: The present invention is directed to a ganged lamp socket device especially applicable for a bank of LED's. The apparatus includes a housing having a row of sockets with a groove and first pockets on one side of the row and a plurality of second pockets on the other side. A common terminal strip fits in the groove and first pockets, while a plurality of contact members fit in the second pockets. The apparatus is easily assembled using the common strip and plurality of contact members formed in a single conductive sheet. The strip is inserted in the groove and broken from the sheet and then the contact members which are held together by a carrier are inserted in the second pockets. The carrier is broken from the contact members and all the items are pressed into place. The apparatus reduces the number of piece parts normally needed for this type of device and increases system reliability.

Abstract: An improved electric lamp including an electrically insulating (e.g., plastic) base which is securedly positioned on the lamp's sealed end portion without the need for adhesives or the like. The base functions to securedly retain the lamp's lead-in wires (a total of four in a dual filament lamp) in a preestablished alignment externally of the lamp's sealed end (from which the wires project) to thereby assure positive electrical connection thereto when the lamp and base are inserted within a corresponding electrical socket. This wire retention is possible by embedding each conductor within designated channels in the base and subsequent deformation of the base's material to substantially cover the embedded wire. In addition, a locking arrangement between the lamp envelope's press sealed end and the base is provided to assist in retaining the sealed end within an opening within the base. The invention is ideally suited for use in a tail light assembly for an automobile.

Abstract: An L-shaped bulb socket comprising an L-shaped socket consisting of a bulb receiving portion and a connector receiving portion and a pair of L-shaped terminal members which are inserted into the socket body through the terminal inserting holes formed in the bulb receiving section and the connector receiving portion of the socket body.
