[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] It should be understood that the terms "front" and "rear" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0043] Please also read Figures 1 to 7 The lamp heat dissipation structure provided by the present invention is now described. The lamp heat dissipation structure comprises a rear shell 1 and heat dissipation fins 2. The rear shell 1 is provided with a bayonet 3. The heat dissipation fins 2 penetrate the bayonet 3. The heat dissipation fins 2 are provided with a buckle member 4 for engaging with the bayonet 3.

[0044] Compared with the prior art, the heat dissipation structure of the lamp provided by the present invention is provided with a bayonet 3 on the rear shell 1, and the heat dissipation fins 2 can pass through the bayonet 3 to achieve pre-positioning during the clamping process, and finally the clamping connection with the bayonet 3 is achieved through the buckle component 4, without the need to use rivets for riveting, the connection structure is simple, the assembly process is simple, and the assembly efficiency can be greatly improved.

[0045] It should be noted that the heat dissipation fins 2 can be disposed on the rear side surface of the rear shell 1 , the outer peripheral surface of the rear shell 1 , etc., which depends on the shape of the rear shell 1 and the position where the light source panel contacts the rear shell 1 .

[0046] Optionally, when the light source board is arranged in contact with the rear wall of the rear shell 1 , the heat dissipation fins 2 are arranged on the rear wall of the rear shell, so that the rear shell 1 can absorb the heat of the light source board as quickly as possible.

[0047] Optionally, the rear shell 1 is a plate-shaped component, the light source board is arranged in contact with the surface of the rear shell 1, and the heat dissipation fins are arranged on the surface of the rear shell 1, which can quickly absorb heat and exchange heat with the air.

[0048] Optionally, the rear shell 1 is a steel component, so that the rear shell 1 has high strength, is not easy to be damaged or replaced when used in a factory environment, and has a long service life; at the same time, the steel material has a large heat transfer coefficient, can quickly absorb heat and transfer it to the heat dissipation fins 2, which is conducive to improving the heat dissipation efficiency. Similarly, the heat dissipation fins 2 are also steel components.

[0049] Please also read Figures 1 to 7 As a specific embodiment of the heat dissipation structure of the lamp provided by the present invention, the buckle component 4 includes a buckle 401 and a limit plate 402. There are multiple buckles 401, and the multiple buckles 401 are respectively located on both sides of the heat dissipation fin 2. The limit plate 402 is arranged at the front end of the heat dissipation fin 2. The buckle 401 and the limit plate 402 are used to clamp the rear shell 1 from the front and rear sides of the bayonet 3.

[0050] The heat sink 2 is gradually inserted into the bayonet 3 from the front side of the rear shell 1, and the heat sink 2 gradually protrudes backward from the bayonet 3. During the insertion process, the buckle 401 is compressed and gradually shrinks, so that the heat sink 2 can continue to move backward. When inserted into place, the limit plate 402 abuts against the front end surface of the bayonet 3. At the same time, the pressure on the buckle 401 disappears, and the buckle 401 automatically resets, forming a clamping and fixing structure with the limit plate 402, thereby preventing the heat sink 2 from falling off from the bayonet 3 during use, thereby improving the stability of use.

[0051] See also Figures 2 to 6 As a specific embodiment of the heat dissipation structure of the lamp provided by the present invention, the buckles 401 are staggered on both sides of the heat dissipation fins 2 along a preset path, and the preset path is parallel to the long axis of the bayonet 3. The staggered arrangement of the buckles 401 can not only meet the requirements of the clamping and fixing on both sides of the heat dissipation fins 2 to balance the force of the heat dissipation fins 2, but also reduce the number of buckles 401 and the volume of the buckles 401, which is convenient for processing and manufacturing.

[0052] See also Figures 1 to 7As a specific embodiment of the heat dissipation structure of the lamp provided by the present invention, the heat dissipation fin 2 includes a side plate 201 and a rear plate 202. There are two side plates 201, which are arranged opposite to each other, and the rear plate 202 is connected to the rear ends of the two side plates 201; there are two limit plates 402, which are respectively arranged at the front ends of the two side plates 201, and a plurality of buckles 401 are respectively arranged on the two side plates 201. The heat dissipation fin 2 is composed of three plate bodies, and the three plate bodies can exchange heat with the air, which increases the contact area between the heat dissipation fin 2 and the air, and greatly improves the heat exchange efficiency of the heat dissipation fin 2; at the same time, since a channel structure is formed inside the heat dissipation fin 2, the channel structure can guide the air, increase the flow rate of the air at the position of the heat dissipation fin 2, and further enhance the heat dissipation effect.

[0053] See also Figures 1 to 7 As a specific embodiment of the heat dissipation structure of the lamp provided by the present invention, two side panels 201 are arranged parallel to each other. The side panels 201, the rear panel 202 and the limit plate 402 form a "J"-shaped structure, which is more compact, simple to process and easy to install.

[0054] See also Figures 1 to 7 As a specific implementation of the heat dissipation structure of the lamp provided by the present invention, a plurality of heat dissipation holes 203 are provided on the rear plate 202. The heat dissipation holes 203 are connected to the inner space of the heat dissipation fins 2, which can enhance the heat dissipation convection efficiency in the heat dissipation fins 2.

[0055] See also Figures 1 to 7 As a specific implementation of the heat dissipation structure of the lamp provided by the present invention, in order to fully utilize the space of the rear plate 202 and expand the area occupied by the heat dissipation holes 203, a plurality of heat dissipation holes 203 are distributed along a preset path.

[0056] See also Figure 3 and Figure 6 As a specific embodiment of the heat dissipation structure of the lamp provided by the present invention, a positioning groove 5 opening toward the front side of the rear shell 1 is provided on the rear shell 1, the bayonet 3 is provided at the bottom of the positioning groove 5, and the limiting plate 402 is used to be clamped in the positioning groove 5. The positioning groove 5 allows the front side of the rear shell 1 to have an inwardly concave space, preventing the limiting plate 402 from protruding from the rear shell 1, ensuring that the rear shell 1 can fit the light source board 7 as much as possible and absorb the heat of the light source board 7 as soon as possible.

[0057] See also Figure 6 As a specific embodiment of the heat dissipation structure of the lamp provided by the present invention, the front plate surface of the limit plate 402 is flush with the front end surface of the positioning groove 5. The limit plate 402 directly fits the rear plate surface of the light source board 7, can directly absorb and transfer the heat generated by the light source board 7, and transfer the heat to the heat dissipation fins 2, which is conducive to improving the heat dissipation efficiency.

[0058] See also Figure 1 , Figures 7 to 15 The present invention also provides a high ceiling lamp, which includes the above-mentioned lamp heat dissipation structure.

[0059] The heat dissipation fin assembly process on the rear shell of the high-bay lamp provided by the present invention is simple, which can effectively improve the overall assembly efficiency of the high-bay lamp and reduce the production cost of the lamp.

The connector 11 is a screw-type connection structure. The lamp can be fixed on the wall by screwing the connector 11. It is easy to install and has high safety. It can meet the safety requirements of special lighting occasions. Specifically, the contact portion 1102 is a conical component, and the connector 11 is consistent with the standard e40 lamp holder, which is easy to install.

[0063] It should be noted that in this structure, some conductive structures, such as wires, extend from the driver box 8 and are conductively connected to the contact portion 1102 and / or the first sleeve 1101, so that the lamp body can be effectively supplied with electricity after being installed in place.

[0064] Optionally, after the first sleeve 1101 and the mounting base 10 are screwed into place, the first sleeve 1101 can be further fixed to the lamp driver box 8 by means of rivets or threaded connectors to prevent the first sleeve 1101 and the mounting base 10 from rotating when installing the lamp, thereby preventing poor contact.

[0065] See also Figure 1 , Figures 7 to 9 As a specific embodiment of the high ceiling lamp provided by the present invention, the connector 11 includes a second sleeve 1104 and a hanging member 1105. The inner wall of the second sleeve 1104 is provided with an internal thread structure. The hanging member 1105 is arranged at the rear end of the second sleeve 1104. The second sleeve 1104 is provided with a first wire hole 1106. The hanging method is a frequently used installation method in the installation of high ceiling lamps. The hanging structure provided by the connector 11 can meet this installation requirement. The wire passes through the first wire hole 1106 to achieve a conductive connection between the lamp body and the outside world.

[0066] Specifically, the lifting component 1105 can be a component such as a lifting ring, a lifting rod, etc., which can meet the installation requirements of a lifting chain, a lifting rope, and a lifting rod.

After the second sleeve 1104 and the mounting seat 10 are screwed into place, relative rotation may still occur, and then the threaded connection position is loosened. Therefore, further fixing by a threaded connector or a rivet can effectively improve the reliability of the connection between the second sleeve 1104 and the mounting seat 10 and avoid safety accidents.

[0068] See also Fig. 9 As a specific embodiment of the high ceiling lamp provided by the present invention, the mounting seat 10 is a cylindrical structure, and the rear end of the side wall of the mounting seat 10 is provided with a avoiding gap 14 corresponding to the first wire hole 1106. The cylindrical structure facilitates the outward routing of the drive box 8, and can also reduce the weight of the mounting seat 10; since the second sleeve 1104 is small in size, the first wire hole 1106 is arranged relatively close to the edge of the second sleeve 1104. In order to avoid squeezing the wire after the mounting seat 10 and the second sleeve 1104 are installed in place, the avoiding gap 14 provides a routing space for the wire.
