Abstract
The utility model relates to an LED illuminant heat radiation structure which is composed of a circuit plate and at least one light emitting diode, wherein the light emitting diode is provided with a metal installing pin and is arranged on the circuit plate arranged in a metal cavity body in which heat conducting adhesive is filled. The metal installing pin of the light emitting diode is completely coated by the heat conducting adhesive. A diversion hole is arranged on the circuit plate. The outer side of the metal cavity body is connected with radiating fins. When the light emitting diode works, heat is transferred to the heat conducting adhesive through the metal installing pin, the heat is transferred to the metal cavity body through the heat conducting adhesive and the heat is emitted from the metal cavity body outwards. The radiating fins connected with the outer side of the metal cavity body can further improve the heat radiation effect. The diversion hole arranged on the circuit plate can conveniently lead the heat conducting adhesive to flow into and vent. The utility model improves efficiency for transferring heat and effectively improves the using efficiency and the service life of the light emitting diode.
