Abstract:
A bulb holder for receiving therein a bulb which has two wires extending downward from the bulb has a body and an adapter connected to the body and having two engaging legs extending downward from a bottom of the adapter to the body for electrical connection with the body and two compartments defined in the adapter by an insulator plate which is formed with the adapter for receiving therein a respective one of the two wires of the bulb. The insulator plate is able to avoid undesirable contact between the two wires.

A socket for discharge lamp is constructed by providing a spiral receiving member and a contact piece in an insulating socket body, and the shortest clearance distance between a socket reference line and the contact piece is defined to at least 19.6 mm.
Abstract:
A halogen lampholder includes a base, a locking spring, two clipping members, two sliding members, a bottom cover, an outer shell and an outer ring. The base is assembled with the locking spring, the clipping members and the sliding members and then, with the bottom cover and the outer shell orderly. The base has a vertical plugging chamber for a fitting portion and two conducting teeth of a lamp to plug in. The locking spring clamps the fitting portion of the lamp. The clipping members connect with the conducting teeth. The sliding members are placed in the base to restrain the locking spring. The bottom cover restrains the locking spring and the clipping members. The outer shell covers the bottom cover, combined with an outer ring and a power-wire tube for a power wire to pass through and reach the clipping members.
Abstract:
An easily assembled and detached wall lamp mounting device comprising a retaining seat, and a locking seat mounted on the retaining seat at one end; and another end of the locking seat being suspended with a wall lamp. The retaining seat is formed by a supporting tube; a receptacle; and a nut stud. The lamp tube has a plug at a position coupled to the retaining seat; and the plug is connected with an electric wire therein. The lamp tube is engaged with a positioning nut. After the plug is inserted into the receptacle of the retaining seat, the plug is tightly screwed into the nut stud for positioning the lamp tube to the retaining seat. In packaging, transferring or storage the lamp seat, the locking seat and the lamp rod are pulled out from the retaining seat in advance for reducing the volume for storage and transfer.
Abstract:
A lampholder has a socket having an inner end and formed with an outwardly open lamp seat defining an axis and adapted to fit with a base of a high-voltage lamp and with a pair of inwardly open blind contact holes. A base fitted against the inner end and formed at the contact holes with respective contact seats has a floor formed in line with each contact hole with an axially throughgoing aperture. Respective contacts in the contact seats are each formed with an abutment arm extending along a wall of the respective contact hole and a spring arm extending into the respective contact hole and elastically deformable from a rest position closely juxtaposed with the respective abutment arm to a holding position spaced therefrom. Thus a conductor pushed through one of the apertures into the respective contact hole will wedge between the contact arms.
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:
The present invention is an improved low voltage track lighting system. The system includes a flat track which may be bent. The track has a flat insulator base with opposed flat sides. The depth of the base is greater than its thickness. A thin flat electrical conductor is fixed to each of the flat sides of the base forming conductors on opposite sides of the base. A step down transformer is adapted to be connected to a source of electric power. A feed mount is adapted to be fixed to a supporting surface to be held by the supporting surface. An electric conductive path in the feed mount is connected to each conductor and to the step down transformer, so that each of the conductors is connected to the step down transformer. An adapter is supported on the track and is in electric contact with each of the conductors of the track. A low voltage lamp is supported on the adapter and in electric contact with the adapter to be energized by an electric current from the step down transformer.
Abstract:
A low voltage track lighting construction in which the transformer is mounted within a housing carried by an elongated track for adjustable movement therealong. A vertically oriented cylindrical member is relatively rotationally adjustable with respect to the housing and depends therefrom. The cylindrical member has a pair of oppositely disposed sockets. Engaging the cylindrical member are a pair of corresponding plugs, each plug supporting a vertically oriented rod section which may be effectively lengthened by engagement with additional sections. Slidably positioned on the rods are a second pair of plug elements, the inner ends of which engage corresponding parts of a lamp holding element to enable the lamp carrying element to be supported for pivotal movement about a horizontal axis. Additionally, the lamp holding element is capable of adjustment along a vertical axis and rotation about the same vertical axis.
Abstract:
A low voltage track lighting system is provided wherein the track transmits current at 12 V AC to standard quartz halogen 12 volt lamps. The track may be made of interlocking components, namely; an electrical strip made of copper tubes partially embedded in a flexible plastic member, and a metal bracket for attachment to a ceiling, wall, or other support. The attachment system between the track and a given fixture uses magnetic attraction, and wherein replaceable magnets in the mount of each fixture attach to the metal bracket of the track to hold the fixture in place and provide the force for contact with the electrical strip.
