Abstract
This utility model discloses a light emitting diode (LED) lamp structure. The LED lamp structure comprises a lamp cap, a heat dissipation base seat with the inside in a hollow structure and a lampshade. An LED light-emitting part is arranged on the upper end portion of the heat dissipation base seat and covered by the lampshade in matched mode, a circuit structure is arranged in the hollow structure in the heat dissipation base seat, and a plurality of heat dissipation through holes communicated with the hollow structure in the heat dissipation base seat are arranged in the surface of the heat dissipation base seat. Therefore, a heat dissipation size of heat dissipation heat transmitting of the heat dissipation base seat can be effectively enlarged. Besides, outward heat dissipation of high-temperature air flows of the LED light-emitting part and the hollow structure in the heat dissipation base seat can be achieved through the heat dissipation through holes, convective heat dissipation is formed, rapid heat dissipation of high-temperature heat of the hollow structure in the heat dissipation base seat toward the periphery of an LED lamp can be achieved, normal work of the LED lamp light-emitting part and an electronic component in the heat dissipation base seat is effectively ensured, and service life of the LED lamp is prolonged. The LED lamp structure has the advantages of being simple in structure, ingenious in conception, convenient, practical and suitable for widespread popularization and utilization.
