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.
A lamp device comprising: a plurality of lamps each of which has a lamp base provided with two electric contacts; a lamp-holding member having two half portions detachably connected with each other, each of said half portions having an annular member with a central opening and a plurality of channel members with a groove extending radially from a periphery thereof which mates with said channel member of another said half portions to define a socket for holding one of said lamp bases of said lamps; a plurality of conducting members positioned among said channel members of said lamp-holding member and connected with said contacts of said lamps so as to form a series circuit; at least two fixing seats mounted diametrically opposite in said lamp-holding member which are adjacent to central openings, each of said fixing seats having a contact member mounted therein and being electrically connected to said series circuit; an elongated insulating column having at least two opposed grooves formed along a length thereof, each of said grooves having a conducting strip fixed therealong, said column being adapted to be passed through said central openings of said lamp-holding member with said conducting strips thereof being slidably engaged with said contact members; whereby said column can pass through a plurality of said lamp-holding members to form a linear lamp assembly; and wherein each of said grooves of said column is generally U-shaped in cross section with a bottom portion and has a channel which is trapezoidal in cross section formed inwardly along said bottom portion of said groove for receiving one of said conducting strips.
