ABSTRACT:
A lamp device includes a lamp-holding member having a first and a second half portion each having an annular member, with a central opening and a plurality of channel members which extend radially from the annular member. Each of the channel members of the first half portion mates with the channel member of the second half portions to define a socket for holding a lamp. A plurality of conducting members are positioned among the channel members of the lamp-holding member and are electrically connected with the lamps mounted to the lamp-holding member to form a series circuit. Two fixing seats are mounted in the lamp-holding member which are diametrically adjacent to the central openings. Each of the fixing seats has a contact member mounted therein and is electrically connected to the series circuit. An elongated insulating column has two opposed grooves formed along the length of the column. Each of the grooves has a conducting strip fixed in the bottom portion of the groove. The insulating column is passed through the central openings of the lamp-holding member with the conducting strips of the insulating column being slidably engaged with the contact members.
