[0040] Reference Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the top appearance of the lamp 100A of the present invention; Figure 2 This is a schematic diagram of the bottom appearance of the lamp 100A of the present invention; Figure 3This is an exploded view of the lamp 100A of the present invention. As a first embodiment of this application, the lamp 100A is a circular industrial lamp. The lamp 100A includes a disc-shaped heat dissipation base 1, a light source plate 2, a snap-fit ​​assembly 3, and a lens 4. To clearly show the snap-fit ​​assembly 3, in... Figure 3 The snap-fit ​​assembly 3 presents its structure as an isometric view, which is different from the perspective of the heat dissipation base 1, the light source plate 2, the snap-fit ​​assembly 3, and the lens 4.

[0042] The light source board 2 is attached to the projection side 12 of the heat dissipation base 1 to provide illumination by emitting light.

[0043] Reference Figures 3 to 9 As shown, Figure 3 This is an exploded view of the lamp 100A of the present invention. Figure 4 This is an exploded view of the snap-fit ​​component 3 of the present invention. Figure 5 This is an exploded view of the snap-fit ​​component 3 of the present invention during assembly. Figure 6 This is an exploded view of the bottom of the lamp 100A of the present invention. Figure 7 This is an exploded view of the lamp 100A of the present invention. Figure 8 yes Figure 7 An illustration of the appearance of the buckle marked A. Figure 9 yes Figure 7 The diagram shows the appearance of the clips selected by circle A. In the first embodiment, five sets of clip components 3 are installed in each limiting recess 15, but this is not a limitation. In some embodiments, multiple sets of clip components 3 may be installed in each limiting recess 15 as needed for the angle.

[0044] In this embodiment, multiple snap-fit ​​components 3 are respectively attached to the assembly side 11 of the heat dissipation base 1 and disposed in each limiting recess 15. Each snap-fit ​​component 3 includes a snap-fit ​​member 31 that is snapped around the lens 4 by each through hole 14. Each snap-fit ​​member 31 has a snap-fit ​​portion 31A and a pivot portion 31B at both ends. The snap-fit ​​component 3 includes multiple snap-fit ​​fixing plates 35, which are locked to the assembly side 11 of the heat dissipation base 1. Each snap-fit ​​fixing plate 35 includes two pivot portions 351A and a shaft 351B. The pivot portion 31B of each snap-fit ​​member 31 is located opposite the two pivot portions 351A and pivotally connected to the shaft 351B.

[0045] In this embodiment, the lens 4 is a thin disc, and is disposed on the projection side 12 of the heat dissipation base 1 to cover the light source plate 2. The lens 4 has multiple angle guides, including a first guide 491, a second guide 492, and a third guide 493 with three angles, which are aligned with the marking part 19 to achieve angle adjustment.

[0046] In this embodiment, the lens 4 has an annular groove 40 around it. When the fastening part 31A of each fastener 31 passes through each through hole 14 to the projection side 12, the fastening part 31A is pried open so that it engages with the corresponding groove 40 on the lens 4. This prying of the fastening part 31A is repeated 5 times. Next, the heat dissipation base 1 has multiple locking parts 124 located on the projection side 12. The lamp 100A includes multiple abutment pieces 7. When each fastener 31 engages with the corresponding groove 40 on the lens 4, each abutment piece 7 is locked to the locking part 124 and pressed against the lens 4, completing the installation.

[0047] In this embodiment, when the lens 4 is adjusted and fixed at an angle, arrow markings are provided on the outer periphery of the lens 4. The first guide portion 491 (60 degrees), the second guide portion 492 (90 degrees), and the third guide portion 493 (120 degrees) can be selected and aligned with the marking portion 19 of the heat dissipation base 1 for alignment. In this embodiment, the lens 4 has multiple protrusions 41 around it, each protrusion 41 adjacent to the slot 40. The protrusions 41 of the lens 4 are rotated with both hands to the desired angle arrow and aligned with the angle markings.

[0048] Reference Figures 12 to 15 As shown, Figure 13 This is an exploded view of the snap-fit ​​assembly 3 of the lamp 100B of the present invention; Figure 14 This is an exploded view of the snap-fit ​​component 3 of the lamp 100B of the present invention during assembly. Figure 14 This is a schematic diagram of assembling a set of snap-fit ​​components 3 onto the heat sink base 1. Figure 15This is an enlarged schematic diagram of the assembled latching assembly 3 of the lamp 100B of the present invention. This is the second embodiment of the present application, and the biggest difference from the first embodiment lies in the latching assembly 3. In this embodiment, the latching assembly 3 includes a spring 32, a latching housing 33, and a latching fixing plate 35. The latching member 31 has a groove at the top to embed the spring 32, and a protruding locking tooth 311 at the bottom, and is provided with a protruding handle 312 and a locking block 315. The spring 32 is installed between the groove of the latching member 31 and the inner wall of the latching housing 33, providing elastic restoring force. The latching housing 33 carries the latching member 31 and the spring 32, and has a through hole 332 and a through hole 335. The latching fixing plate 35 covers the outside of the latching housing 33, and has a recessed hole 352 and a locking hole 355 to restrict the movement of the protruding handle 312 and the locking block 315.

[0049] In this embodiment, when installing the buckle assembly 3, the spring 32 is first assembled with the buckle 31. The spring 32 is vertically inserted into the groove 313 of the buckle 31, ensuring it is fully embedded with a click or a distinct tactile feedback, indicating it is in place. Next, the buckle housing 33 is installed, placing the assembled buckle 31 and spring 32 into it. It is pressed in vertically until the bottom engages with the groove, and the spring 32 is compressed. Then, the semi-finished buckle housing 33 is installed on the assembly side 11 of the heat dissipation base 1, and the buckle fixing plate 35 is installed. The buckle fixing plate 35 covers the semi-finished buckle housing 33, and screws 3 are used to lock it in the locking hole on the assembly side 11. At this moment, the protruding shank 312 of the buckle 31 protrudes through the through hole 332 of the buckle housing 33 and the recessed hole 352 of the buckle fixing plate 35, with the through hole 335 aligned with the locking hole 355.

[0050] Reference Figure 16 As shown, Figure 16 This is an exploded view of the heat dissipation base 1 and sealing ring 5 of the lamp 100B of the present invention during assembly. In this embodiment, the sealing ring 5 is a circular washer, which is installed in the annular groove 125 to provide a waterproof structure for the lens 4 and the heat dissipation base 1.

[0051] In this embodiment, during the installation of the sealing structure, the sealing ring 5 is first placed on the heat dissipation base 1, and then the sealing ring 5 is embedded into the annular groove 125 of the projection side 12. The fit is checked to prevent it from falling off. Next, the lens 4 is installed on the projection side 12 of the heat dissipation base 1, and the lens 4 is pressed onto the sealing ring 5. Each latching cantilever 43 of the lens 4 passes through the through hole 14 of the heat dissipation base 1 and engages with the protruding latching teeth 311 of the latching member 31.

[0052] As described above, multi-angle adjustment is achieved by rotating lens 4. Furthermore, the luminaire 100B requires no tools throughout the entire process; installation or removal can be completed simply by pressing and aligning. A reliable seal is formed between the sealing ring 5 and the annular groove 125, achieving an IP65 rating. The snap-fit ​​structure, in conjunction with spring 32, ensures the lens 4 is securely fixed and not easily loosened. The lens can be replaced or adjusted at any time, significantly reducing maintenance and installation time.

[0053] Reference Figure 12 and Figure 17 As shown, Figure 17 This is a schematic diagram showing the appearance of the heat dissipation base 1 and lens 4 of the lamp 100B of the present invention when assembled. In this embodiment, the lens 4 is a thin disc, and the lens 4 is disposed on the projection side 12 of the heat dissipation base 1 to cover the light source plate 2. The outer periphery has multiple fastening cantilever arms 43 and locking holes 431 for engaging with the fastener 31. The lens 4 has multiple angle guide portions. In this embodiment, the lens 4 includes a first guide portion 491, a second guide portion 492, and a third guide portion 493 with three angles, which are aligned with the marking portion 19 to achieve angle adjustment.

[0054] In this embodiment, when adjusting and fixing the lens 4, arrow markings are provided on the outer periphery of the lens 4. The first guide portion 491 (60 degrees), the second guide portion 492 (90 degrees), and the third guide portion 493 (120 degrees) can be aligned with the marking portion 19 of the heat dissipation base 1. Next, the snap-fit ​​slot is pressed in, and each snap-fit ​​cantilever 43 of the lens 4 is pressed to embed it into the snap-fit ​​member 31. Then, the protrusion 312 of the snap-fit ​​member 31 is gently pulled to test and confirm that the spring 32 can rebound and the snap-fit ​​is not loose, and then it can be installed and assembled. Conversely, when disassembling, the protrusion 312 is pushed by hand to disengage the protruding teeth 311 of the snap-fit ​​member 31 from the snap-fit ​​cantilever 431, and then the lens 4 can be rotated and pulled out to complete the disassembly.

[0055] As described above, multi-angle adjustment is achieved by rotating the lens. Furthermore, the entire installation and removal of the lamp requires no tools; installation or removal is completed simply by pressing and aligning. A reliable seal is formed between the sealing ring and the annular groove, achieving an IP65 rating. A snap-fit ​​structure combined with a spring ensures the lens is securely fixed and not easily loosened. The lens can be replaced or adjusted at any time, significantly reducing maintenance and installation time.

[0056] The embodiments described above are merely illustrative of the technical ideas and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the patent scope of the present invention. In other words, all equivalent changes or modifications made in accordance with the spirit disclosed in the present invention should still be covered within the patent scope of the present invention.

[0057] In summary, it is evident that this invention, by breaking through previous technologies, has indeed achieved the desired enhanced effects, and is beyond the comprehension of those skilled in the art, demonstrating its creativity and practicality.
