A lamp device includes a lamp, a socket, two magnetic electrodes, and two electrode boxes. The lamp comprises a bulb portion, a stem portion, and two magnetic contacts. The socket has a receptacle portion configured to accept the lamp. The two magnetic electrodes are disposed in the receptacle portion. Each of the two electrode boxes encloses each of the two magnetic electrodes. The magnetic electrode is free to move in the electrode box, and the magnetic electrode makes an electrical contact all the time. The lamp device may further comprise a guiding groove and an insulating wall. The guiding groove may be provided on a bottom surface of the lamp between the two magnetic contacts.

A connecting member is adapted to be coupled with a connection object including a pipe portion having a sealed end and a terminal portion protruding outward from the sealed end. The connecting member includes a tubular portion adapted to be fitted over an outer peripheral surface of the pipe portion, a bottom portion connected to one end of the tubular portion in an axial direction and adapted to be faced to the sealed end when the tubular portion is fitted over the outer peripheral surface of the pipe portion, and a connecting portion connected to the bottom portion and adapted to be connected to the terminal portion. The tubular portion includes a plurality of elastic sections separated by a plurality of slits extending from the other end towards the one end in the axial direction and adapted to be brought into elastic contact with the pipe portion.
摘要:
The oblong bulb (1) of the lamp is sealed at opposing ends by sealing pieces (6; 32), with application of a holder to each end, whereby said holder comprises an electrical contact element (13; 25), electrically connected to a power supply (15; 21), running to the lighting means. The contact element is housed in a tubular extension (11; 22) of the sealing piece and the maximum external diameter of the contact element (13; 25) is loosely matched to the inner diameter of the sleeve.

The present invention comprises a unique starter assembly for a gas discharge lamp. The starter assembly comprises a main current path with a first leg connected to one electrode of a gas discharge lamp, and a second leg connected to a second electrode of the gas discharge lamp. A starting current path is provided between the first and second electrode, and comprises an magnetic switch. The magnetic switch is actuated by an electromagnet controlled by a control circuit. The control unit may be programmed with the start time required for a particular lamp design. In an alternative embodiment, the starter assembly further comprises a radio frequency identification system. The radio frequency identification system includes a gas discharge lamp transponder. The lamp transponder is used to communicate specific lamp information to the control circuit. The control circuit may then modify the start time for that lamp based on this information.
