Led lamp

An LED lamp, comprising:

• a light source part, comprising a light source board and a plurality of LED beads arranged on the light source board, wherein the light source board is an annular plate and is disposed on a first side of the light source part;
• a heat dissipation part connected on a second side of the light source part, the heat dissipation part comprising a plurality of heat dissipation fins be in radial distribution and perpendicular to the light source board;
• a power supply part disposed at a center of the light source board and connected to the heat dissipation part;
• and
• a heat dissipation channel arranged between the power supply part and the light source part, wherein the heat dissipation fins of the heat dissipation part are parallel to the heat dissipation channel,
• wherein the projections of the light source part and the heat dissipation part in a light emitting direction of the LED lamp are spaced apart from the power supply part and surround the power supply part.
