Led lamp with a fan and manufacturing method thereof

A LED lamp with a fan, comprising a lamp body sleeving a lamp holder, and a lamp cover connected to the lamp body, characterized in that,

• the lamp body consists of an upper lamp body and a lower lamp body connected by a fixing element;
• the upper lamp body is a prism, an external wall of a facet of the prism is covered with a LED aluminum substrate, and all the LED aluminum substrates are connected to a LED PCB along the circumference of the LED PCB, a capacitor is soldered at the center of the bottom of the LED PCB, and the capacitor is received in a capacitor box, a LED driving circuit is received in the bottom of a cavity of the lamp holder, and a fan is received in an opening end of the cavity of the lamp holder, an annular body of the capacitor box contacts with and fixes the fan;
• the LED driving circuit, the fan and the LED PCB are connected by a wire;
• a plurality of axially-arranged air outlet flues are opened in the lamp cover and extend into inner cavity of the lamp cover, a penetrating hole matching the air outlet flue and penetrated by the air outlet flue is opened in the LED PCB;
• a heat dissipation passageway of the LED lamp consists of:
• an air inlet arranged in an annular wall extending inwards from an inner wall of a recess ring of the lower lamp body, the air inlet communicating with the air outside of the LED lamp,
• a window opened in an outer wall of the lamp holder with the outer wall matching the air inlet of the lower lamp body,
• an air outlet formed between the annular body and a plurality of beams,
• a penetrating hole and an air flow channel opened in the upper lamp body, and
• the air outlet flue butting against the penetrating hole of the upper lamp body.
