Spherical light bulb and heat dissipating device thereof

A spherical light bulb, comprising:

• a connector;
• a driver module including a driver electrically connected to the connector;
• a heat dissipating device including a barrel-shaped member, a plurality of heat dissipating fins protruding from the barrel-shaped member, a supporting member arranged on one end of the barrel-shaped member, and a connecting portion arranged around the supporting member and adjoined to the heat dissipating fins, wherein the supporting member has a supporting surface and a heat dissipating channel formed therein in communication with the inside of the barrel-shaped member and the supporting surface, wherein the driver is arranged in the barrel-shaped member, wherein a slot is concavely formed on the inner surface of the barrel-shaped member in communication with a plurality of gaps formed between the heat dissipating fins, whereby allowing the gaps between the heat dissipating fins to communicate with the heat dissipating channel;
• a light source unit arranged on the supporting surface of the supporting member;
• and
• a substantially spherical-shaped transparent light cover having an opening formed thereon, wherein the transparent light cover has a flanged portion around the opening for securing to the connecting portion, wherein the supporting member passes through the opening and is arranged inside the transparent light cover.
