7. LED filament lamp according to claim 1 wired wick it is characterised in that：Described wired structure is LED
The two end electrodes of silk (10), according to the requirement of LED circuit both positive and negative polarity, are respectively put into electrode seal wire and seal wire end of connecting simultaneously
After in crotch, the crotch of seal wire is made to close, then LED filament (10) is tightly led in stem stem (20) electrode seal wire and series connection by clamping
In the crotch of silk.
8. a kind of processing technology of the wired wick based on the arbitrary described LED filament lamp of claim 1 to 8 it is characterised in that
Comprise the following steps：
Step 1, upper stem stem, the series connection seal wire (205) on stem stem is carried out shaping, by electrode seal wire (203) to away from stem stem
(20) the side bending of axial line, is folded into the axial line of the axial line of part that electrode seal wire (203) bends and stem stem (20)
Vertically, and one end of one end and electrode seal wire (203) of series connection seal wire (205) is corresponded；
Step 2, by series connection seal wire (205) and electrode seal wire (203) rounded ends flatten so that seal wire of connecting (205) flat
Two flat transverse planes of shape end are parallel to each other, and the flat end of described series connection seal wire (205) flat transverse plane vertical or
Horizontal tangent plane parallel to stem stem (20) axial line；Make two flat transverse planes of the flat end of electrode seal wire (203) mutual
Parallel, and the flat transverse plane of the flat end of described electrode seal wire (203) is perpendicular or parallel to the horizontal stroke of stem stem (20) axial line
To tangent plane；
Step 3, the series connection seal wire (205) after flattening and the flat end of electrode seal wire (203) curve hook, respectively connect
Guide wire hook and electrode guide wire hook, and the length of hook of described series connection guide wire hook and electrode guide wire hook is more than or equal to
0.6mm, the angle of hook is less than 90 °；
Step 4, a termination electrode of LED filament (10) is put in series connection guide wire hook, and the other end of LED filament (10) is electric
Pole is put in electrode guide wire hook；After putting into, will connect guide wire hook and electrode guide wire hook closure are so that LED filament
(10) two end electrodes are separately fixed in series connection guide wire hook and in electrode guide wire hook.
