Embodiment
The utility model is described further below in conjunction with the drawings and specific embodiments.
It refer to accompanying drawing 1-6, a kind of lamp of LED filament 6, including lamp holder 2, cell-shell 4,4 filaments 6 and dual openings stem 8.
Two openings and one up and down that the dual openings stem 8 includes mutually deviating from are used for the connecting portion of two openings of connection
82, periphery and the surrounded by edges of cell-shell 4 of lower ending opening 84 cause one cavity of formation of cell-shell 4；The connecting portion 82 is axially
Provided with passage, through there is some metal wires 9 in the passage, the one end of metal wire 9 passes through upper end open 86 and the electricity of filament 6
Connection, the other end is electrically connected with lamp holder 2；
The two ends of filament 6 are provided with exposed electrode；Between one end of the filament 6 electrode be welded to each other to be formed one it is public
Summit, the other end is fixedly connected with the upper end open 86 of the dual openings stem 8, forms cone structure, the conduct of filament 6
The incline of the cone structure.
In the present embodiment：Upper and lower two openings have the structure that diameter gradually increases, form along in departing direction
