Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to a ring lens for LED lighting. Background Technology

[0002] The ring lens design of LED luminaires is typically designed to optimize light distribution, improve lighting efficiency, and enhance visual comfort. Through its specific geometry and refractive index distribution, a ring lens can concentrate or diffuse the light generated by the LED to a specific area, thereby achieving uniform lighting or emphasizing a particular illuminated zone.

[0003] Chinese Patent CN221705273U discloses a ring lens for LED lamps, comprising a lens body, a support block bolted to the inner wall of the lens body, a reinforcing lens assembly bolted to the inner wall of the support block, a mounting bracket bolted to the inner wall of the reinforcing lens assembly, a mounting mechanism snapped into the inner wall of the mounting bracket, a pre-installed bracket at the top of the mounting mechanism, the bottom of the pre-installed bracket in close contact with the top of the mounting mechanism, and a sealing component snapped into the inner wall of the reinforcing lens assembly. This invention addresses the problems of existing LED lamp ring lenses, which mostly lack enhanced illumination and typically use a single ring lens for illumination, resulting in limited illumination intensity. Furthermore, the current installation of most LED lamp ring lenses is cumbersome, requiring multiple bolts for fixation, which makes subsequent disassembly and maintenance difficult and inconvenient for users.

[0004] However, the above technical solution has the following shortcomings: Although the device avoids the use of multiple bolts, reducing the difficulty of subsequent disassembly and maintenance, the connection between the support block and the lens body, the strengthening lens assembly, and the connection between the mounting bracket and the mounting mechanism are fixed by adhesive because there are no bolts. This method is not only cumbersome to operate, but also prone to damage when disassembling the parts, reducing the practicality of the lens. Utility Model Content

[0022] Example 1

[0023] like Figures 1-4 As shown in the figure, the annular lens of the LED lamp proposed in this embodiment includes a lens body 1 and a connecting mechanism; a reinforcing lens ring 2 is provided on the inner ring side of the lens body 1, and multiple lens seats 21 distributed in an annular array and two sealing rings 22 are provided on both the lens body 1 and the reinforcing lens ring 2. The sealing rings 22 are used for sealing and moisture prevention.

[0024] like Figure 1 and Figure 2 As shown, the connecting mechanism includes a first fixing block 3 and a second fixing block 4 respectively disposed on the lens body 1 and the reinforcing lens ring 2, a connecting rod 5 for connecting the first fixing block 3 and the second fixing block 4, and a snap-fit ​​assembly disposed inside the first fixing block 3 and the second fixing block 4. The first fixing block 3 and the second fixing block 4 are each provided with two symmetrically distributed sliding grooves 6 inside, and the snap-fit ​​assembly is located inside the sliding grooves 6.

[0025] The snap-fit ​​assembly includes a wedge 7 slidably disposed in a groove 6, a guide rod 8 disposed on the wedge 7, and springs 9 disposed at both ends on the wedge 7 and the groove 6 respectively. The springs 9 are sleeved on the guide rod 8. The end of the guide rod 8 away from the wedge 7 passes through the first fixing block 3 and the second fixing block 4. A ball gripping 10 is disposed on the guide rod 8, and a slot for the wedge 7 to be inserted is disposed on the connecting rod 5.

[0026] In this embodiment, the illumination intensity of the light source is improved by the reinforced lens ring 2. When installing the reinforced lens ring 2, the two ends of the connecting rod 5 are pressed against the wedges 7 inside the first fixing block 3 and the second fixing block 4, respectively. The wedges 7 slide into the groove 6 under the pressure, and the spring 9 is compressed at the same time. When the connecting rod 5 is pressed to the bottom, the slot and the wedges 7 are aligned. Under the action of the spring 9, the wedges 7 are embedded in the slot, thus completing the fixed connection between the lens body 1 and the reinforced lens ring 2. When it is necessary to disassemble it, the guide rod 8 is pulled outward by holding the ball 10, so that the wedges 7 are disengaged from the slot, and the connecting rod 5 can be removed. The operation is simple and convenient, and has good practicality.

[0027] Example 2

The locking plates 13 are provided with positioning holes 17 with a rectangular cross section. The fixing component includes an insert block 14 that passes through the mounting blocks 11 and the locking plates 13, an elastic pad 15 arranged on the insert block 14, and a fitting block 16 that is inserted and connected to the insert block 14.

[0029] In this embodiment, when it is necessary to fix the connecting ring 12 and the reinforcing lens ring 2, the locking plate 13 is first embedded into the mounting block 11 so that the positioning hole 17 is aligned with the through hole of the mounting block 11. Then, the insert block 14 is inserted and passes through. During the insertion process, due to the elastic pad 15 provided on the insert block 14, the insert block 14, the mounting block 11, and the locking plate 13 will be tightly squeezed, thereby completing the fixation of the locking plate 13. At the same time, the other end of the insert block 14 is inserted in conjunction with the fitting block 16, further improving the stability of the connection.
