Moreover, the LED lamp is compact in structure, the purpose of miniaturization is achieved, and the assembling process of the LED lamp is simplified.

The invention is described below in connection with specific embodiments with reference to the following drawings.

Fig. 1 is a schematic structural diagram of an LED lamp according to an embodiment of the present invention, and fig. 2 is an exploded schematic structural diagram of the LED lamp according to the embodiment of the present invention.

Referring to fig. 1 and 2, an embodiment of the present invention provides an LED lamp 100, including: the LED lamp includes a lamp housing 160, an LED module 110 disposed within the lamp housing 160, two connectors 120, two cap electrodes 130, and a driving module 140.

Specifically, the two connecting members 120 are respectively disposed at two ends of the LED module 110, and fix the LED module 110 between the two connecting members 120, the lamp cap electrodes 130 are disposed at two ends of the two connecting members 120 far away from the LED module 110, the two lamp cap electrodes 130 are respectively electrically connected to two ends of the LED module 110, and the lamp cap electrodes 130 take electricity from an external power source and provide the electricity to the LED module 110, so as to supply power to the LED module 110.

Of course, the present invention is not limited thereto, and in the embodiment of the present invention, the driving module 140 is disposed in one of the connection members 120, and one end of the LED module 110 is electrically connected to the cap electrode 130 through the driving module 140. The connector 120 may further include a heat conductive paste (not shown), and the heat conductive paste may be coated on a sidewall of the connector 120.

In this way, the heat emitted from the LED module 110 and the driving module 140 can be rapidly dissipated to the air through the connecting member 120 and the heat conducting mud, so as to improve the heat dissipation effect of the LED lamp 100. In addition, the connecting member 120, the driving module 140, the cap electrode 130 and the electrical wiring are disposed at two ends of the LED module 110, so that the LED lamp 100 has a compact structure, the miniaturization can be achieved, and the assembly process of the LED lamp 100 is simplified.

It should be noted that the connecting member 120 may be a cylindrical tube, a rectangular tube, a conical tube, or a tube body with other shapes, and in an exemplary embodiment, one end of the connecting member 120 facing the lamp cap electrode 130 is open, the cross section of the opening may be a circular surface or an elliptical surface, a receiving cavity formed by the connecting member 120 is used for placing the driving module 140 and/or routing a wire, the other end of the connecting member 120 is a semi-closed surface, and an opening on the semi-closed surface is used for extending the wire to be electrically connected to the LED module 110. The present embodiment does not limit the shape of the connection member 120.

The connecting member 120 may be made of heat-dissipating plastic, ceramic, or metal, and the material used for the connecting member 120 is not limited in this embodiment.

It is easy to understand that, the LED chips are disposed on both sides of the substrate 111, so that 360 ° light emission can be realized, and the substrate 111 has a small size, so that the LED lamp 100 can be more miniaturized and light-weighted.

The LED module 110 may be loosened due to unstable abutment of the LED module 110 between the two connectors 120, or the LED module 110 may not be snapped into the mounting position due to the mounting position being smaller than the end of the LED module 110.

To solve the above problem, fig. 4 is another exploded schematic view of an LED lamp according to an embodiment of the present invention. Referring to fig. 2 and 4, in some embodiments of the present invention, a single connecting member 120 may be divided into two half cylinders, one end of each half cylinder having an inclined surface, the two inclined surfaces of the two half cylinders forming a fixing surface 121, and a gap 122 between the two inclined surfaces, the gap 122 forming a mounting position.
