Apparatus and methods for supporting a fluorescent lamp. The apparatus may include a ballast and one or more lamp holders. The lamp holders may be in electrical communication with the ballast via a conductor. One or more lamp holders may be removably attachable to the ballast. When a lamp holder is attached to the ballast, it may be attached in a manner that places the lamp holder in electrical communication with the conductor. The apparatus may include a lamp holder module that may support one or more lamp holders. When a lamp holder is attached to the lamp holder module, it may be attached in a manner that places the lamp holder in electrical communication with a conductor that is configured to distribute power to lamp holders that are attached to the lamp holder module.

A socket assembly includes a rotor assembly, a housing, and at least one electrical contact. The rotor assembly has an axis of rotation and defines a channel having a length about perpendicular to the axis of rotation. The rotor assembly is adapted to receive at least one lamp pin within the channel from an edge of the rotor assembly. Each of the at least one lamp pin defines a longitudinal axis. Each of the axis of each of the at least lamp pin is about parallel to the axis of rotation when each of the at least one lamp pin is received from the edge of the rotor assembly to within the channel. The housing is adapted to receive the rotor assembly such that the rotor assembly is rotatable along its axis of rotation therein. The housing defines a notch adapted to receive each of the at least one lamp pin when each of the axis of each of the at least one pin is about parallel to the axis of rotation. The rotator assembly is rotatable to at least first and second positions and the channel of the rotor assembly aligns with the notch of the housing when in the first position such that each of the at least one lamp pin is received through the notch of the housing and into the channel of the rotor assembly. A least one electrical contact is disposed within the housing and an electrical contact of the at least one electrical contact is adapted for operative engagement with a lamp pin of the at least one lamp pin. The electrical contact is operatively disengaged from the lamp pin when the rotor assembly is in about the first position and operatively engages the lamp pin when the rotor assembly is rotated at least substantially to the second position.

There is provided a backlight device with which it is possible not only to prevent an assembly process from being complicated and the number of components from being increased, but also to connect a light source to a connector member satisfactorily and electrically. In this backlight device (20), a distance (W12) from the central axis (O1) of a cold cathode fluorescent lamp (23) to a connector terminal portion (240) is larger than a distance (W2) from the central axis of the cold cathode fluorescent lamp to an end portion of a contact portion (23d) of a cap portion (23a) in an F direction but is smaller than a distance (L2) from the central axis of the cold cathode fluorescent lamp to an end portion of the contact portion of the cap portion in an E direction.

A discharge tube 17 of the present invention includes a glass tube 60 and ferrules 70 disposed around ends of the glass tube 60. Outer leads 61 for receiving power from an external power source project from ends of the glass tube 60. Each ferrule 70 includes a body 71 that is fitted onto the glass tube 60 and an insertion portion 73 that is disposed near the end of the body 71 and into which the outer lead 61 is inserted. The outer lead 61 includes a loop portion 62 at the end thereof. The outer lead 61 is electrically connected with the ferrule 70 when the loop portion 62 is inserted in the insertion portion 73.
摘要:
A lamp connector allows for checking of a connection between an external electrode of an external electrode tubular lamp and a terminal fitting into which the external electrode is fitted. Because the lamp connector into which an external electrode provided on the outer surface of an end portion of a tubular lamp is fitted includes a terminal fitting which includes a terminal piece and a terminal piece insulated from each other which are to be individually brought into contact with the external electrode, it is possible to easily check conduction between the external electrode and the terminal fitting using a tester. Accordingly, any poor fitting of the lamp into the connector can be readily found and corrected.

A lamp socket that supports a lamp including a lamp body and one or more electrodes protruding from opposite end portions of the lamp body and that electrically connects an inverter circuit board driving the lamp and the lamp includes: a socket terminal having a first stopper where the electrodes are inserted in a first direction crossing a lengthwise direction of the electrodes to be held, the socket terminal providing an elastic force in a second direction substantially crossing the lengthwise direction of the electrodes and the first direction, whereby the first stopper is closely held to the electrodes.
摘要:
The lamp socket according to the invention demonstrates a housing (2) with a rotor (26). Contacts (15, 16), which demonstrate contact tags (17) that are resilient in the swivel direction, are mounted in the housing (2). The open ends (18) of the contact tags can support themselves on stopping means (31 to 34), which are moved by the rotor (26). In the support position, they are positioned on the ends (18) of the contacts (15, 16). When the lamp is rotated from its insertion position into its connected position, the support means (31 to 34) are distant from the ends (18) of the contacts (15, 16), however, so that the lamp can be rotated relatively freely without current. Only near the end of this rotational movement do cams provided on the support means (31 to 34) bump against the ends (18) of the contacts (15, 16) and force them radially inwards and clamp the contacts (15, 16) against the pins (45, 46) of the lamp.
