Abstract:
Fixtures, apparatuses, and related methods are provided that provide for a non-Edison connection for receiving a lamp housing of a lighting device having a non-Edison connector. The fixture can include a fixture housing and a non-Edison socket securable to the fixture housing. The fixture can also include an engagement device for engaging a lamp housing of a lighting device that has a non-Edison connector upon insertion of the lamp housing into the fixture housing and engaging the non-Edison socket.
Abstract:
A lamp socket adapter/converter has a main body with a medium screw-base male lamp connector on a lower end and a mount on an upper end. Standoffs extend from the mount parallel and spaced from a central axis. A printed circuit board has holes engaged with medial portions of the standoffs, and a mounting plate fixed to a female bi-pin socket is engaged with the terminal ends of the standoffs. Circuit components on the circuit board convert the electricity present at the lower end lamp connector to a different form of electricity provided to the bi-pin socket. Potting material surrounds an upper portion of the mount, the printed circuit board, the circuit components, the mounting plate and a lower portion of the bi-pin socket.
Abstract:
An adapter for providing a recessed lamp in a screw-type lampholder. This adapter has an electrical contact-making device, via which an electrical connection is produced between a screw base, which can be introduced into the screw-type lampholder, of the adapter and the recessed lamp once the recessed lamp has been introduced into the adapter. Furthermore, the adapter has a switchable electrical connecting device, via which, in the state in which there is no mechanical connection between an enveloping bulb for the recessed lamp and the adapter, an electrical connection is not produced between the screw base and the recessed lamp, and via which, in the state in which the recessed lamp is surrounded, at least in sections, by the enveloping bulb, an electrical connection is produced between the screw base and the recessed lamp. As a result, the recessed lamp in the adapter can only be operated with the enveloping bulb placed thereon.
Abstract:
A mounting board has a board, retaining members mounted on the upper surface of the board, and a part retained by the retaining members. The part is mounted such that at least a part thereof is arranged below the lower surface of the board, and that the part is electrically connected to the board through the retaining members. Such an arrangement as described above eliminates the need of connecting the discharge gap element to the board by using lead wires, and of mounting it on the upper surface of the board. This lowers the height of the board and admits an elevated part.
Abstract:
A lampholder has an outer sleeve centered on an axis and having a radially inwardly projecting lug having an axially inwardly directed end face and an inner core adapted to fit with a lamp, fittable inside the sleeve, and formed with an axially inwardly directed face axially alignable and engageable with the outer-sleeve end face on rotation of the core in the sleeve in a predetermined sense in a fully inserted position of the inner core in the sleeve. Interengageable retaining formations on the core and on the sleeve inhibit rotation of the core in the sleeve opposite to the predetermined sense when the faces are axially aligned with and engage each other.
Abstract:
A lock-in compact fluorescent lamp (CFL) adaptor that would be screwed into the socket of a conventional incandescent lamp assembly. It has an adaptor casing whose respective top wall, bottom wall and outer side walls form an electrical components chamber for a ballast, a printed circuit board, and electrical wiring. A CFL post member socket is formed in the top wall of the adaptor casing. An electrical contact base is connected to the bottom wall of the adaptor casing and it has a conventional externally threaded outer electrical contact surface that would be received into a conventional incandescent lamp socket. The adaptor has structure to prevent unauthorized removal of the compact fluorescent lamp from the adaptor. The adaptor casing also has a pair of vertically oriented slots for receiving and capturing the bottom legs of a harp used with a lamp assembly. One alternative embodiment of the adaptor has a removable electrical contact base. Another alternative embodiment has an adaptor designed to function with a compact fluorescent lamp having an inverted base structure.
Abstract:
A clamping structure of projection lamp comprises a shade assembly, a lamp cup and a clamping tongue. The shade assembly has an insulating body with two grooves on two outer walls thereof. The lamp cup has two leads connected to the shade assembly. The lamp cup has two grooves on two outer walls thereof. The clamping tongue has a resilient main body having a plurality of upper arms and lower arms on two opposite sides thereof. The upper arm has upper clamping part and the lower arm has lower clamping part. The upper clamping parts of the upper arms clamp the grooves of the shade assembly and the lower clamping parts of the lower arms clamp the grooves of the lamp cup such that the lamp cup is elastically connected to the shade assembly.
Abstract:
A lamp holder includes a base and two electrical contacts for forming a connection with a bulb having an envelope around an electrical filament having two wires extending therefrom. Each wire forms a loop protruding from the envelope, the two loops being at opposed ends of the envelope. Each electrical contact of the lamp holder has a wire with a hook at its free end and formed to engage one of the two loops of the bulb, so that a shorter one of the wires engages the one of said two loops at the nearer end of the bulb and the other larger spring wire engages the other of said two loops at the far end of the bulb, in a manner that induces a spring tension in the wire. Thus, the bulb is held suspended between, and in electrical contact with, the two loops.
Abstract:
A festoon lamp holder has a base provided with recesses either side of probes. A cap permanently fits to the base to provide a water-tight seal with an electrical cable passing in use through the holder. Power is provided from the cable conductors via feed-throughs for a bulb. A globe surrounds the bulb and provided with seals forms a gas-tight chanber for the bulb.
Abstract:
A light assembly including a light socket and an electric lamp, wherein the light socket includes a connection base with at least two conductor-openings and a lock-opening having a lock portion and an open portion, and the lamp includes a light source, a connection base with two conductive protrusions to engage with the socket conductor- opening and a locking-protrusion on the lamp connection base shaped and/or sized for insertion into the open portion of the socket lock-opening and movement into the lock portion only after insertion into said open portion. The locking protrusion, lock-opening and conductor-openings are respectively configured to allow relative movement of the lamp connection base with respect to the socket connection base to effect the attachment and removal of the lamp from the socket via the lock-opening.
