Description

Technical Field

[0001] This application relates to the field of lighting devices, and in particular to a lighting fixture. 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 a single lighting fixture for use.

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

[0004] In view of the above-mentioned related technologies, the connecting member is fixed to the housing by injection molding, which has the defect of insufficient connection strength and needs to be improved. Utility Model Content

[0005] In order to improve the connection strength between the connecting member and the housing body, this application provides a lighting fixture.

[0006] The lighting fixture provided by this application adopts the following technical solution:

[0007] A lighting fixture includes a housing body and a connecting member. One end of the housing body facing the connecting member is provided with an installation platform. The upper end surface of the installation platform is horizontally arranged and penetrated with an installation hole. The connecting member includes a connecting ring, and one side of the connecting ring facing the installation platform is provided with a clamping member that is clamped with the inner side of the installation platform.

[0008] By adopting the above technical solution, the connecting ring and the installation platform are clamped with each other by setting the clamping member, so that the clamping member can be detachably connected to the housing body directly by clamping. On the one hand, it is convenient for the disassembly and assembly of the connecting member and has sufficient connection strength. On the other hand, the housing body can directly form an insulating layer through the spray coating process without using injection molding to fix the connecting member. Spray coating has the advantages of high production efficiency and lower production cost compared with injection molding.

[0009] Optionally, the clamping member is set as a buckle plate, and the inner wall of the installation platform is provided with a buckle block that cooperates with the buckle plate.

[0010] By adopting the above technical solution, the fixing of the connecting member is completed through the mutual buckling of the buckle plate and the buckle block, and its structure is simple and the connection strength is relatively high.

[0011] Optionally, two buckles are provided, and the two buckles are symmetrically arranged on the connecting ring.

[0012] By adopting the above technical solution, the symmetrically arranged buckles can effectively improve the balance of force, thus ensuring good structural strength.

[0013] Optionally, a guide groove matching with the buckle is arranged on the upper end surface of the mounting table, and the guide groove communicates with the mounting hole.

[0014] By adopting the above technical solution, through the arrangement of the guide groove, it is convenient to extrude and deform the buckle and squeeze it into the mounting hole, without the need for the staff to additionally squeeze and bend the buckle.

[0015] Optionally, reinforcing ribs are arranged on one side of the buckle facing the mounting hole.

[0016] By adopting the above technical solution, the reinforcing ribs can improve the structural strength of the buckle, effectively reduce the situation of its fracture or damage, and at the same time ensure its recoverability after deformation.

[0017] Optionally, two positioning posts are arranged on one side of the connecting ring facing the mounting table, and two positioning holes for the positioning posts to pass through are penetrated on the mounting table.

[0018] By adopting the above technical solution, through the arrangement of the positioning posts, on the one hand, it has a guiding effect, which is convenient for the formation of a fit between the clamping member and the mounting table, and on the other hand, it can share the force and limit the rotation of the connecting member, further improving the structural strength.

[0019] Optionally, a positioning ring is arranged on one side of the connecting ring facing the mounting table, and the outer side wall of the positioning ring abuts against the inner wall of the mounting hole.

[0020] By adopting the above technical solution, through the arrangement of the positioning ring, the matching effect between the connecting member and the mounting table can be further improved, resulting in higher structural strength.

[0021] Optionally, positioning protrusions are arranged on both sides of the clamping member on the inner wall of the mounting hole, and positioning notches matching with the positioning protrusions are arranged at the positions of the positioning ring corresponding to the positioning protrusions.

[0022] By adopting the above technical solution, the matching arrangement of the positioning protrusions and the positioning notches can, on the one hand, further improve the limiting effect, and on the other hand, further share the force and limit the rotation of the connecting member, and at the same time also further improve the structural strength.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By providing a snap - fitting member, the connection ring and the mounting platform are snap - connected to each other, enabling the snap - fitting member to be detachably connected to the outer housing directly by snap - fitting. On the one hand, it facilitates the disassembly and assembly of the connecting member and has sufficient connection strength. On the other hand, the outer housing can directly form an insulating layer through the powder coating process without using injection molding to fix the connecting member. Powder coating has the advantages of high production efficiency and lower production cost compared to injection molding;

[0025] 2. Through the provision of the positioning posts, on the one hand, it has a guiding effect, facilitating the cooperation between the snap - fitting member and the mounting platform. On the other hand, it can share the force and limit the rotation of the connecting member, further improving the structural strength;

[0026] 3. Through the provision of the positioning ring, the cooperation effect between the connecting member and the mounting platform can be further improved, generating higher structural strength. The cooperative setting of the positioning protrusion and the positioning notch, on the one hand, can further improve the limiting effect. On the other hand, it can further share the force and limit the rotation of the connecting member, and also further improves the structural strength. Brief Description of the Drawings
