Description

Technical Field

[0001] This application relates to the field of lighting devices, and in particular to a high heat dissipation lamp. Background Art

[0002] LEDs have the advantages of high luminous efficiency, power saving, and long lifespan, and their applications are becoming more and more widespread. When LEDs are applied to general lighting, in order to meet the illumination requirements, multiple high-power LEDs are generally concentrated on one lamp for use.

[0003] In related technologies, high-power LED lamps use aluminum shells to have good heat conduction and dissipation effects, and an insulating layer is formed by injection molding on the shell surface. The shell and the screw socket are connected by a connecting piece. The inner side of the screw socket and the PCB board are electrically connected by wires, and the outer side of the screw socket and the lamp socket are electrically connected. The connecting piece is made of plastic material to insulate the shell and the screw socket from each other, and the connecting piece is fixed on the shell synchronously when injecting the insulating layer.

[0004] In view of the above related technologies, for high-power LED lamps, even though the aluminum shell has good heat conduction and dissipation effects, there are still serious heat generation defects during long-term use, resulting in a relatively fast aging rate of the hardware and limiting its service life.

[0021] By adopting the above technical solution, the connecting parts are mutually clamped through the buckle plate and the installation platform, and the structure is simple and easy to install.

[0022] Optionally, a buckle block cooperating with the buckle plate is provided on the side of the installation platform facing away from the connecting ring, and a guide groove cooperating with the buckle plate is provided on the side of the installation platform facing the connecting ring, and the guide groove is connected to the installation hole.

[0023] By adopting the above technical solution, the buckle plate is deformed and guided by the setting of the guide groove, which makes it easier for the buckle plate to be inserted into the installation hole and form a snap fit with the buckle block.

[0024] Optionally, two positioning posts are provided on one side of the connecting ring facing the mounting platform, and two positioning holes for inserting the positioning posts are penetrated through the mounting platform.

[0038] Referring to Figure 1 、 Figure 2 , a heat dissipation protrusion 5 is integrally formed on the inner wall of the housing 1 near the screw socket 3, and a heat dissipation groove 6 is arranged on the outer side wall of the housing 1 corresponding to the heat dissipation protrusion 5, so that the heat dissipation protrusion 5 and the heat dissipation groove 6 are arranged in a concave shape facing the inside of the housing 1. This concave structure is arranged axially with the housing 1 and is located above the housing 1.

[0039] Referring to Figure 1 、 Figure 2 , a mounting post 7 is integrally formed at the bottom of the heat dissipation groove 6. The mounting post 7 is arranged axially with the heat dissipation groove 6, and a heat dissipation hole 8 axially penetrates through the mounting post 7 and the heat dissipation protrusion 5.
