Abstract:
An air-cooled lamp bulb includes a central tube and a circular light wall. The circular light wall is formed by a plurality of light units surrounding the central tube and emitting light beams in a direction away from the central tube. A top frame supports the circular light wall on top. A top opening is formed in the top frame. A bottom gap is formed between a bottom of the central tube and a bottom of the circular light wall. An air passage is formed between the central tube and the circular light wall. The air passage connects the top opening and the bottom gap for allowing air flow through the air-cooled lamp bulb.
