Abstract
The invention discloses a light emitting diode (LED) lamp structure capable of efficiently dissipating heat. The LED lamp structure comprises a lamp cap, a heat dissipating base with a hollow structure at the inner part and a lampshade, wherein an LED luminescent piece is arranged at the upper end part of the heat dissipating base and shaded by the lampshade; a circuit structure is assembled in the hollow structure at the inner part of the heat dissipating base; and a plurality of heat dissipating through hole communicated with the hollow structure at the inner part of the heat dissipating base are formed in the surface of the heat dissipating base. The heat dissipating area for heat dissipation and heat transfer of the heat dissipating base can be effectively increased, and high temperature airflow of the LED luminescent piece and the hollow structure at the inner part of the heat dissipating base can dissipate heat outwards through the heat dissipating through holes, so that heat dissipation through convection is formed, high temperature heat of the hollow structure at the inner part of the heat dissipating base is rapidly dissipated towards the periphery of the LED lamp, normal operation of the LED luminescent piece and electronic elements at the inner part of the heat dissipating base is effectively protected, the service life of the LED lamp is prolonged; and the LED lamp structure has a simple structure, is designed ingeniously, is very simple and practical, and is suitable for general popularization and use.
