Abstract:
A lampholder has a socket having an inner end, formed with seats adapted to hold contacts, and forming an outwardly open hole defining an axis and adapted to fit with a base of a high-voltage lamp and a base fittable against the inner end and having a floor formed with an axially throughgoing hole. A clip is formed with a bight engaged in the hole, a pair of arms extending from respective ends of the bight axially outward into the socket, outer tabs on the arms bearing axially inward on the socket, and inner tabs at the bight bearing axially outward on the floor of the base so that the clip holds the socket and base together.
Abstract:
A lighting fixture assembly includes a unitary housing having a reflector, neck and wire receiving portion. Electrical circuits include electrically conductive strips housed in a circuit support comprising mating halves. A mid-portion is removed from one strip to form a modular electrical circuit that is coupled to a thermal cut-off device also housed in the circuit support which is disposed within the housing neck. The wire receiving portion includes semi-cylindrical walls with opposed gaps that define a path for receiving a power supply line. Piercing pins of the circuits protrude above the circuit support. An adapter includes a curved recess for receiving a power supply line and directing the line to make contact with the piercing pins. A removable cap is mated to the wire receiving portion to apply force onto the adapter, thereby causing the power supply line to be pierced by the pins.
Abstract:
A shade assembly of projection lamp comprises an insulating body, two fixing members, two conductive plates and two resilient members. The insulating body has two receiving spaces therein and two insertion holes. The two fixing members each has a receiving recess for the conductive plate, one end of the fixing member is inserted and tightened into the receiving space. The two conductive plates each has a first lateral side and a second lateral side. The two conductive plates being arranged within the receiving recesses for a conductive plate; the conductive plate has a bottom end facing the insertion hole. Each of the two resilient members is provided between the insulating body and the conductive plate to enhance the clamping force for the conductive plate. The receiving space has an inner wall provided with an indent groove to prevent dragging out of the fixing member.
Abstract:
A socket intended to receive and make electrical contact between an electrical unit, such as a wedge based light bulb, and a connector. A core including an inner cylinder is provided with an insertion opening at one end. There is an electrically conductive terminal which includes a unit contact at the distal end within the inner cylinder and adjacent the insertion opening. A connector contact extends from the proximal end of the conductive terminal, remote from the distal end, through a terminal hole in the inner cylinder, out of the interior space, and into a connector receiver. The terminal is provided with contacts to receive the unit, and a wall plate adjacent the inner side wall of the inner cylinder. In addition, there is a shield plate adjacent a proximal end which overlies the terminal hole, thereby preventing entry of molding resin into the interior space where it can impair the integrity of the connection.
Abstract:
This invention relates to a festoon lamp holder, and to a lighting system incorporating such a lamp holder. The lamp holder comprises a molded cap and base, and forms a pressure-tight seal with the supply cable, and a water-tight seal with a removably attached globe. Between the cap and base, lugs with detents engage within a groove, and through a camming action on a tapered post, engage permanently with a retaining means, thereby locking the detents within the groove. Probes between the cap and base pierce the cable, which may be used to support the lamp holder in a festoon lighting system. The lamp may be a low voltage halogen lamp and may also be formed as a festoon bulb held perpendicular to the lamp holder by hooked wires.
Abstract:
A light-bulb socket has two main parts, namely a socket cup having a base provided with a pair of upwardly exposed contacts and formed with a plurality of throughgoing mounting holes and a base disk fitted tightly to the base of the cup and formed with passages through which conductors connected to the contacts can pass. The base disk is unitarily formed with a pair of mounting sleeves projecting upward through the mounting holes of the cup. The sleeves are formed as short tubes that are a tight force fit in the mounting holes and are each formed with a deformable rib to enhance the tight fit.
Abstract:
A lamp socket mounting bracket which contains a pair of mounting clamps and is mounted within a reflector. The mounting clamps have reflector ends and socket ends which each have feet. The mounting clamps have curved portions to encompass a lamp socket which forms a fulcrum within the lamp socket mounting bracket. A clamp adjusting means is used at the socket ends of the mounting clamps to tighten the mounting clamps around the lamp socket, help make a substantial contact between the mounting clamps and the lamp socket, and create, along with the fulcrum, a reverse scissors action within the lamp socket mounting bracket.

1,020,950. Lamp cups or holders. AMP CORPORATION. Nov. 27, 1964 [Nov. 30, 1963], No. 48282/64. Heading H2E. An electrical connector for use with an iodine lamp having a central blade contact 8 and an outer 'rectangular contact 4, has an inner contact 1 held by resilient detent 13 within an insulating block 2, and an outer contact 3 which fits over the forward end of block 2 and is held by a resilient projection 21 on the 'block, engaging in a hole 26 of the contact. Both contacts have crimping ferrules, those 11 and 19 of the inner contact being located within a rear transverse recess 10 in the block, and these 27 and 28 of the outer contact being positioned between projections 22. The inner contact has a projection on its base to engage the hole on the central blade contact 8 of the lamp, and the outer contact has depressions 25 to engage the outer contact of the lamp. On engagement of the lamp in its holder, the arms of the inner contact are resiliently forced outwards against the constraint of the block 2.
Abstract:
The present invention relates to a screw-in type base for a lighting device being arranged to be mounted in a socket comprising a socket bottom conductor is provided. The base (100, 200, 300) comprising a threaded tubular enclosure (102) extending along an axial direction between a first (102a) and a second (102b) end portion of the enclosure (102), a base bottom conductor (103, 203, 311) arranged to be in electrically conductive contact with a light source (106) of the lighting device (400), and arranged to make electrically conductive, biased contact with the socket bottom conductor when the lighting device (400) is mounted in the socket, wherein the base bottom conductor (103, 203, 311) comprises a compliant thin-walled member (105, 205, 308) arranged such that the base bottom conductor (103, 203, 311) is, relative to the enclosure (102), movable in the axial direction in response to engagement with the socket bottom conductor when the lighting device (400) is mounted in the socket. The present invention also relates to a lighting device (400) comprising the base.
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.
