Abstract (en)

A light-emitting diode (LED) light bulb structure includes a glass stem (20), a first power wire (21), a second power wire (22), a first conducting bar (31), a second conducting bar (32), a first light-emitting module (40), and a second light-emitting module (50). Each of the first light-emitting module (40) and the second light-emitting module (50) has a top bar assembly, a bottom bar assembly and multiple LED filaments (41, 43, 45, 47). Both ends of each of the top bar assembly and the bottom bar assembly are respectively connected with the first conducting bar (31) and the second conducting bar (32). The LED filaments (41, 43, 45, 47) are mounted between the top and bottom bar assemblies to form an alternating U-shaped series-connected circuit loop passing through the multiple LED filaments (41, 43, 45, 47) and the top bar assembly and the bottom bar assembly.
