摘要： A LED lamp filament, comprising: a long strip-shaped substrate, a plurality of light-emitting units arranged on a first surface of the substrate and distributed along the extending direction of the substrate, and a light-transmittable fluorescent glue layer covering the first surface and the plurality of light-emitting units. A plurality of bulges are provided on at least one side of the substrate, and the bulges are distributed along the extending direction of the substrate; one part of light excited by the fluorescent glue layer and emitted from the light-emitting units emits out in a direction towards a second surface, opposite to the first surface, of the substrate from a space between adjacent bulges.
