Conventionally, a light-emitting diode is used as a light source of a light source, which has the advantages of a long life cycle and good light-emitting efficiency compared to a conventional light-emitting element. A light-emitting diode lamp generally needs to use an initiator to receive an input voltage and provide an output voltage to the plurality of light-emitting diodes to control the plurality of light-emitting diode switches. Since the starter of the conventional light-emitting diode lamp is placed in the lamp cap of the lamp and cannot be effectively dissipated, the creator of the creation develops an "electronic lighting device" and obtains the Republic of China patent No. M460224, however, this Although the method of suspending the starter in the heat dissipation module can improve the heat dissipation problem of the starter of the conventional light-emitting diode lamp, the heat transfer efficiency of the gas molecules in the air is not good, so that the heat dissipation efficiency of the conventional technology is generated. Limitations.

The purpose of this creation is to further improve the heat dissipation efficiency of the starter and the light-emitting diode of the lamp, thereby increasing the durability of the lamp.

In order to achieve the above purpose, the LED lamp structure of the present invention comprises a heat dissipation module, a light emitting module, a lamp head and a starter, and the light emitting module and the lamp head are respectively connected to two sides of the heat dissipation module. The heat dissipation module is integrally formed, and has a base portion and a connecting plate at a position of an inner axis of the base. The connecting plate is connected to the inner wall of the base portion, and a plurality of heat radiating fins are extended from the outer edge of the base portion. The starter has a circuit board and an activation component disposed on a surface of the circuit board. The starter is adhered to the connecting plate in the heat dissipation module by the thermal grease. Thereby, the thermal energy generated by the starting component of the starter can be directly transmitted to the thermal grease and the heat dissipation module for heat dissipation, so as to obtain better heat dissipation efficiency. The light-emitting module has a heat-conducting plate and a light-emitting diode disposed on the heat-conducting plate, and the heat-conducting plate is fixed on the base surface of the heat-dissipating module, so that the heat generated by the light-emitting diode can be directly transmitted to the heat-conducting plate and the heat-dissipating module. Cool down.

According to the above technical means, the thermal energy generated by the LED and the starting component of the present invention is directly transmitted to the heat dissipation module for heat dissipation, thereby obtaining better heat dissipation efficiency.
