摘要： An LED filament assembly includes a frame, a first electrode disposed on a first end of the frame, and a second electrode disposed on a second end of the frame. The LED filament assembly includes a first group of LED chips capable of emitting a first color, a second group of LED chips capable of emitting a second color, and a third group of LED chips capable of emitting a third color. The first group of LED chips is disposed on the frame along a longitudinal axis, connected in series, and electrically connected to the first electrode and the second electrode. Similarly, the second and the third group of LED chips are also disposed on the frame along the longitudinal axis, connected in series, and electrically connected to the first electrode and the second electrode. A lamp including such an LED filament assembly is also disclosed.
