[0026] The lamp housing 1 provided in the embodiment of the present invention is now described.

[0027] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 4 The lamp housing 1 includes a first lamp tube 11, a second lamp tube 12 and a threaded locking ring 13, and the threaded locking ring 13 is used to lock the first lamp tube 11 and the second lamp tube 12. The first lamp tube 11 is inserted into the second lamp tube 12, and the end of the first lamp tube 11 has an insertion portion 110, and the outer periphery of the first lamp tube 11 radially protrudes outward to form a first annular ring 111. Specifically, the first annular ring 111 divides the first lamp tube 11 into two parts, one of which is the insertion portion 110. The outer periphery of the second lamp tube 12 radially protrudes outward to form a second annular ring 121. When the insertion portion 110 of the first lamp tube 11 is inserted into the second lamp tube 12, the first annular ring 111 of the first lamp tube 11 and the second annular ring 121 of the second lamp tube 12 abut against each other, so that the first lamp tube 11 and the second lamp tube 12 are axially positioned. The inner ring of the threaded locking ring 13 is provided with an internal thread and a limiting annular groove 131, and the internal thread and the limiting annular groove 131 are sequentially distributed along the axial direction of the threaded locking ring 13. The threaded locking ring 13 is threadedly connected to one of the first annular ring 111 and the second annular ring 121, and the other of the first annular ring 111 and the second annular ring 121 is clamped in the limiting annular groove 131. When the threaded locking ring 13 is rotated and tightened, the side wall of the limiting annular groove 131 and the threaded connection structure cooperate to press the first annular ring 111 and the second annular ring 121, thereby fixing the first lamp tube 11 and the second lamp tube 12. Specifically, when installing the lamp, first insert the light-emitting module 2 into the first lamp tube 11 or the second lamp tube 12, then plug the first lamp tube 11 and the second lamp tube 12, and finally lock the threaded locking ring 13. When disassembling the lamp, rotate and loosen the threaded locking ring 13, and then pull the first lamp tube 11 out of the second lamp tube 12 to disassemble the lamp. It can be seen that the lamp in this embodiment is easy to disassemble and assemble. After reinstallation, the threaded locking ring 13 can still press the first lamp tube 11 and the second lamp tube 12 against each other, so the lamp can be quickly restored after maintenance to ensure the original waterproof performance.

[0028] The lamp housing 1 in the above embodiment includes a first lamp tube 11, a second lamp tube 12 and a threaded locking ring 13. The first lamp tube 11 and the second lamp tube 12 are axially positioned by inserting the insertion portion 110 of the first lamp tube 11 into the interior of the second lamp tube 12 and making the first annular ring 111 of the first lamp tube 11 and the second annular ring 121 of the second lamp tube 12 abut against each other. One of the first annular ring 111 and the second annular ring 121 is located in the limiting annular groove 131 in the threaded locking ring 13, and the other of the first annular ring 111 and the second annular ring 121 is threadedly connected with the threaded locking ring 13, so that the first annular ring 111 and the second annular ring 121 are locked, and the first lamp tube 11 and the second lamp tube 12 are fixed to each other. Since the threaded locking ring 13 can quickly lock the first lamp tube 11 and the second lamp tube 12, and can also be quickly removed, and can press the first lamp tube 11 and the second lamp tube 12 against each other, the lamp can be quickly restored after maintenance to ensure the original waterproof performance.

[0029] In one embodiment of the present invention, see Figure 4 The end surface of the threaded locking ring 13 extends radially inward to form an axial limiting portion 132. The side of the axial limiting portion 132 and the inner ring of the threaded locking ring 13 together form the above-mentioned limiting annular groove 131. The side of the axial limiting portion 132 can press the side of the second annular ring 121. The outer periphery of the first annular ring 111 is provided with an external thread. The threaded locking ring 13 is threadedly connected to the first annular ring 111, and the side of the axial limiting portion 132 presses the second annular ring 121. Under the joint action of the threaded connection structure and the axial limiting portion 132, the first annular ring 111 and the second annular ring 121 are pressed. In this embodiment, the threaded locking ring 13 is inserted from the end of the second lamp tube 12 away from the first lamp tube 11. The end of the second lamp tube 12 away from the first lamp tube 11 is the light emitting end. Therefore, there is no structure at this end to block the threaded locking ring 13, and the threaded locking ring 13 can be easily inserted.

[0030] In another embodiment of the present invention, the end surface of the threaded locking ring 13 extends radially inward to form an axial limiting portion 132, and the side surface of the axial limiting portion 132 and the inner ring of the threaded locking ring 13 jointly form the above-mentioned limiting annular groove 131, and the side surface of the axial limiting portion 132 can press the side surface of the first annular ring 111. The outer periphery of the second annular ring 121 is provided with an external thread, the threaded locking ring 13 is threadedly connected to the second annular ring 121, and the side surface of the axial limiting portion 132 presses the first annular ring 111, and under the joint action of the threaded connection structure and the axial limiting portion 132, the first annular ring 111 and the second annular ring 121 are pressed.

[0031] In one embodiment of the present invention, see Figure 4, a sealing ring 113 is provided between the insertion part 110 and the second lamp tube 12. When the first lamp tube 11 and the second lamp tube 12 are installed with each other, the sealing between the first lamp tube 11 and the second lamp tube 12 can be achieved to prevent water vapor from entering the interior of the lamp housing 1 through the gap between the insertion part 110 and the second lamp tube 12. Specifically, the outer wall of the insertion part 110 and the inner wall of the corresponding second lamp tube 12 are the joint surfaces of the first lamp tube 11 and the second lamp tube 12. The outer wall of the insertion part 110 may be provided with an annular accommodation part 112 for accommodating the sealing ring 113. The number of the annular accommodation parts 112 may be multiple, and they are arranged and distributed in sequence along the axial direction of the first lamp tube 11. In other embodiments, the annular accommodation part 112 may also be provided on the inner wall of the second lamp tube 12. The number of the annular accommodation parts 112 may be multiple, and accordingly, a sealing ring 113 is provided in each annular accommodation part 112, which can enhance the waterproof performance of the lamp.

[0032] In one embodiment of the present invention, see Figure 1 and Figure 2 The outer periphery of the thread locking ring 13 has a friction portion, which can enhance the friction between the thread locking ring 13 and the hand, making it easier to unscrew the thread locking ring 13. The structure of the friction portion is not specifically limited here, and can be serrated, convex, patterned, etc., as long as it can increase the roughness of the surface of the thread locking ring 13.

[0033] The present invention also provides a lamp, see Figure 3 The lamp includes the lamp housing 1 in any of the above embodiments, and also includes a light emitting module 2, which is arranged inside the lamp housing 1. Specifically, when installing the lamp, the light emitting module 2 is first installed, and then the light emitting module 2 is placed in the first lamp tube 11 as a whole, the second lamp tube 12 is plugged into the first lamp tube 11, and finally the threaded locking ring 13 is tightened.

[0034] The lamp provided by the present invention adopts the above-mentioned lamp housing 1, and the lamp housing 1 includes a first lamp tube 11, a second lamp tube 12 and a threaded locking ring 13. The axial positioning of the first lamp tube 11 and the second lamp tube 12 is achieved by inserting the insertion portion 110 of the first lamp tube 11 into the interior of the second lamp tube 12, and making the first annular ring 111 of the first lamp tube 11 and the second annular ring 121 of the second lamp tube 12 abut against each other. One of the first annular ring 111 and the second annular ring 121 is located in the limiting annular groove 131 in the threaded locking ring 13, and the other of the first annular ring 111 and the second annular ring 121 is threadedly connected with the threaded locking ring 13, so that the first annular ring 111 and the second annular ring 121 are locked, and the first lamp tube 11 and the second lamp tube 12 are fixed to each other. Since the threaded locking ring 13 can quickly lock the first lamp tube 11 and the second lamp tube 12, and can also be quickly removed, and there is no need to design a buckle on the lamp housing 1, the processing and installation efficiency will be improved.

[0035] In one embodiment of the present invention, see Figure 3 The light-emitting module 2 includes a module structure, a circuit board 24 and a light source assembly 25. The module structure is a support for the entire light-emitting module 2. The circuit board 24 and the light source assembly 25 are both fixed to the module structure. The module structure may be cylindrical and fixed inside the lamp housing 1.

[0036] Optionally, the outer peripheral protrusion of the module structure is provided with a third annular ring 212, one end of the module structure extends into the first lamp tube 11, and the third annular ring 212 abuts against the end of the insertion portion 110, so that the axial position of the module structure relative to the first lamp tube 11 is limited, and the other end of the module structure extends into the second lamp tube 12. In this way, the module structure can be prevented from axially moving inside the lamp housing 1.

[0037] Optionally, a buffer ring 114 is provided between the module structure and the insertion part 110, and the function of the buffer ring 114 is to prevent the light-emitting module 2 from shaking circumferentially and radially inside the lamp housing 1. The number of the buffer rings 114 can be selected to be one or more. When the number of the buffer rings 114 is more than one, the buffer rings 114 are arranged in sequence along the axial direction of the module structure. More specifically, an annular receiving groove is provided on the outer periphery of the module structure for accommodating the buffer ring 114; or, an annular receiving groove is provided on the inner ring of the insertion part 110 for accommodating the buffer ring 114; or, an annular groove is provided on the outer periphery of the module structure and the inner ring of the insertion part 110, and the two corresponding annular grooves are combined to form an annular receiving groove for accommodating the buffer ring 114.

[0038] In one embodiment of the present invention, see Figure 3 A first magnetic component 31 is provided inside the lamp housing 1, and a second magnetic component 32 is fixed on the module structure. The first magnetic component 31 and the second magnetic component 32 attract each other, so that when the light-emitting module 2 is installed, the light-emitting module 2 can be quickly positioned with the lamp housing 1, which can speed up the installation speed and ensure the consistency of the installation position. Among them, when the lamp housing 1 is a metal shell, a plastic adapter 33 is fixed inside the lamp housing 1. The plastic adapter 33 can be fixed to the inside of the lamp housing 1 by dispensing or threaded connection, and the first magnetic component 31 is fixed to the plastic adapter 33. The processing difficulty and cost of the metal lamp housing 1 are relatively high. By providing the plastic adapter 33, the structural complexity of the metal lamp housing 1 can be reduced and the processing cost can be reduced.

[0039] Optionally, the module structure includes a module bracket 21, a base 22 and a face ring 23, and the base 22 and the face ring 23 are respectively fixed to opposite ends of the module bracket 21. When one end of the first lamp tube 11 is closed and the other end is open, one end of the base 22 of the module structure is arranged inside the first lamp tube 11, and the second magnetic member 32 can be fixed on the base 22, and the base 22 can be provided with a receiving groove, and the second magnetic member 32 is arranged in the receiving groove, and can be fixed in the receiving groove by adhesives or the like. When one end of the first lamp tube 11 is closed and the other end is open, both ends of the second lamp tube 12 are open. In this way, when installing the lamp, the light-emitting module 2 is first installed into the first lamp tube 11 (the bottom is closed), and then inserted into the second lamp tube 12.

[0040] Optionally, the base 22 can be snap-connected or fixed to the module bracket 21 by screws. A positioning groove can be provided on the side of the base 22 facing the module bracket 21, and the module bracket 21 is convexly provided with positioning ribs. When the base 22 and the module bracket 21 are assembled, the positioning ribs are inserted into the positioning grooves, and the base 22 can be well positioned, and then the base 22 is fixed to the module bracket 21 by snaps or screws.

[0041] Optionally, the module bracket 21 may be cylindrical and have a partition 211 inside. The circuit board 24 is arranged on one side of the partition 211, and the circuit board 24 and the base 22 are arranged on the same side, which is convenient for connecting the output line with the external power supply. The light source assembly 25 is arranged on the other side of the partition 211, and the light source assembly 25 is also electrically connected to the circuit board 24. The light source assembly 25 is pressed against the module bracket 21 through the face ring 23. That is, the base 22, the circuit board 24, the light source assembly 25, and the face ring 23 can be arranged in sequence along the light emitting direction. The light source assembly 25 may include a light source board, a lens, etc. The circuit board 24 and the base 22 are arranged on one side of the partition 211, and the light source assembly 25 is arranged on the other side of the partition 211, so that the layout of the light emitting module 2 is more compact, and the electrical connection structure is arranged on the back of the light source assembly 25.

[0042] Optionally, the face ring 23 is threadedly connected to the inner wall of the module bracket 21. After the light source assembly 25 is installed on the module bracket 21, the face ring 23 is tightened to the module bracket 21, so that the light source assembly 25 is clamped between the partition 211 and the face ring 23, so as to fix the light source assembly 25. The face ring 23 can be removed by rotating in the opposite direction, so the light source assembly 25 can be easily removed, and the lens and other light source assembly 25 can be manually replaced, and manual focusing can be achieved.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
