[0025] Please refer to Figure 1 , Figure 1 which is an exploded structural schematic diagram of the lamp provided by the embodiment of the present invention. The embodiment of the present invention provides a lamp 1, and the lamp 1 includes a base 100, an inner ring assembly 200, an outer ring assembly 300, and a driving power source 400. The inner ring assembly 200, the outer ring assembly 300, and the driving power source 400 are all arranged inside the base 100.

[0026] Please refer to Figure 2 , Figure 2 which is a structural schematic diagram of the base of the lamp provided by the embodiment of the present invention. The base 100 is provided with an inner cylinder 110, an inner ring groove 120, and an outer ring groove 130. The inner ring groove 120 and the outer ring groove 130 are sequentially located on the outer periphery of the inner cylinder 110.

[0027] The inner ring assembly 200 includes a gland 210, an adjusting ring 220, a first inner ring 230, a second inner ring 240, an inner ring waterproof ring 250, an elastic member 260, and a lens plate 270.

[0028] Among them, the gland 210 is fixed to the inner cylinder 110 and presses the inner periphery of the adjusting ring 220. The first inner ring 230 and the second inner ring 240 are both arranged in the inner ring groove 120, and the second inner ring 240 is arranged above the first inner ring 230. The elastic member 260 elastically abuts between the first inner ring 230 and the second inner ring 240. The lens plate 270 is pressed on the second inner ring 240, and the lens plate 270 is provided with a plurality of first adjusting portions 271 with gradually increasing sizes. The adjusting ring 220 is pressed on the lens plate 270 and is rotatably arranged relative to the inner cylinder 110 on the same horizontal plane. The adjusting ring 220 is provided with at least one second adjusting portion 221 that cooperates with the first adjusting portion 271. When the adjusting ring 220 rotates relative to the inner cylinder 110 on the same horizontal plane, the second adjusting portion 221 cooperates with the first adjusting portions 271 of different sizes, so that the lens plate 270 has different assembly heights relative to the base 100.

[0029] Please refer to Figure 3 , Figure 3It is a partial structural cross-sectional view of the lamp provided by the embodiment of the present invention. The lamp 1 includes a light source substrate 340, and the light source substrate 340 is disposed in the base 100 between the inner ring groove 120 and the outer ring groove 130. The first adjusting portion 271 may be a plurality of recessed areas with gradually increasing depths, and the second adjusting portion 221 is at least one convex block portion that cooperates with the recessed areas of the first adjusting portion 271. Alternatively, the first adjusting portion 271 is a plurality of convex block portions with gradually increasing heights, and the second adjusting portion 221 is at least one recessed area that cooperates with the convex block portions of the first adjusting portion 271. The recessed area is in the shape of a V-shaped groove and points to the center of the inner cylinder 110, and the convex block portion is in the shape of a V-shaped block and points to the center of the inner cylinder 110. In this embodiment, the first adjusting portion 271 may be three, namely the first recessed area 2711, the second recessed area 2712, and the third recessed area 2713, where the depths of the first recessed area 2711, the second recessed area 2712, and the third recessed area 2713 increase in sequence. The second adjusting portion 221 may be three, namely the first convex block portion 2211, the second convex block portion 2212, and the third convex block portion 2213, where the heights of the first convex block portion 2211, the second convex block portion 2212, and the third convex block portion 2213 increase in sequence. When the adjusting ring 220 rotates relative to the inner cylinder 110, for example, from the first convex block portion 2211 to the second convex block portion 2212, the recessed area on the lens plate 270 that cooperates with it rotates from the first recessed portion 2711 to the second recessed portion 2712, the depth dimension of the recessed area becomes larger, the assembly height of the lens plate 270 relative to the base 100 becomes smaller, the assembly height of the light source substrate 340 in the base 100 relative to the lens plate 270 also becomes smaller, the incident angle of the light from the light source substrate 340 passing through the lens plate 270 becomes larger, and after being refracted by the lens plate 270, the exit angle of the light from the light source substrate 340 also becomes larger, and the exit angle of the light changes from 60° to 90°. On the contrary, if it rotates from the third convex block portion 2213 to the second convex block portion 2212, the recessed area on the lens plate 270 that cooperates with it rotates from the third recessed portion 2713 to the second recessed portion 2712, the depth dimension of the recessed area becomes smaller, the corresponding assembly height of the lens plate 270 relative to the base 100 becomes larger, the assembly height of the light source substrate 340 relative to the lens plate 270 also becomes larger, the incident angle of the light from the light source substrate 340 passing through the lens plate 270 becomes smaller, and after being refracted by the lens plate 270, the exit angle of the light from the light source substrate 340 also becomes smaller, and the exit angle of the light changes from 110° to 90°. Thus, by simply rotating the adjusting ring 220, the change of the beam angle of the lamp 1 is realized.

[0030] Optionally, according to actual requirements, through precise optical design, by changing the height and number of the recessed areas or convex block portions of the lens plate 270, or by changing the optical properties (such as refractive index) of the lens plate 270, it is possible to achieve that the same lamp 1 can output light with more beam angles.

[0031] Different from the prior art, the lamp 1 provided in this application is provided with a plurality of first adjusting parts 271 with gradually increasing sizes on the lens plate 270. The adjusting ring 220 is pressed on the lens plate 270 and is rotatably arranged relative to the inner cylinder 110 on the same horizontal plane. The adjusting ring 220 is provided with at least one second adjusting part 221 that cooperates with the first adjusting part 271. When the adjusting ring 220 rotates relative to the inner cylinder 110 on the same horizontal plane, the second adjusting part 221 cooperates with the first adjusting parts 271 of different sizes, so that the lens plate 270 has different assembly heights relative to the base 100, thereby changing the incident angle of the light from the light source substrate 340 onto the lens plate 270. After being refracted by the lens plate 270, the exit angle of the light from the light source substrate 340 also changes among 60°, 90°, and 110°. Thus, the same lamp 1 can achieve light output with three different beam angles through simple adjustment, greatly optimizing the on-site lighting effect, improving the flexibility of the application of the lamp 1, and improving the lighting experience of users.

[0032] Please refer to Figure 4 , Figure 4 which is a schematic exploded view of the waterproof part of the lamp provided by an embodiment of the present invention. The lamp 1 further includes a first outer ring 310, a second outer ring 320, and an outer ring waterproof ring 330. The first outer ring 310 is arranged in the outer ring groove 130, and the second outer ring 320 is arranged above the first outer ring 310. A guiding structure member is provided between the first inner ring 230 and the second inner ring 240. The elastic member 260 is a spring and is sleeved on the outer periphery of the guiding structure member. The elastic member 260 can apply a continuous upward acting force to the lens plate 270 to ensure a certain distance is reserved between the lens plate 270 and the lamp beads on the light source substrate 340. In this embodiment, the first inner ring 230 and the second inner ring 240 are provided with a plurality of concave holes 241, and guide posts and guide sleeves 242 are arranged in the concave holes 241. The guide posts and guide sleeves 242 of the first inner ring 230 are inserted and sleeved in cooperation with the guide sleeves and guide posts 242 of the second inner ring 240. The first outer ring 310 and the second outer ring 320 are provided with a plurality of concave holes 321, and guide posts and guide sleeves 322 are arranged in the concave holes 321. The guide posts and guide sleeves 322 of the first outer ring 310 are inserted and sleeved in cooperation with the guide sleeves and guide posts 322 of the second outer ring 320. The elastic member 260 is a spring, and both ends of the spring abut against the bottom of the concave hole 241 and are sleeved on the outer periphery of the guide posts and guide sleeves 242. The lens plate 270 is pressed on the second inner ring 240, causing the lens plate 270 to only move axially in a small range along the inner cylinder 110 through the expansion and contraction of the spring.

[0033] When the adjusting ring 220 rotates relative to the inner cylinder 110, for example, from the first bump portion 2211 to the second bump portion 2212, the recessed area on the lens plate 270 that mates with it rotates from the first recessed portion 2711 to the second recessed portion 2712, and the depth dimension of the recessed area becomes larger, resulting in a smaller distance between the first inner ring 230 and the second inner ring 240. The elastic member 260 is compressed, and the lens plate 270 moves downward along the axial direction of the inner cylinder 110, and the distance between the lens plate 270 and the light source substrate 340 becomes smaller. Conversely, if it rotates from the third bump portion 2213 to the second bump portion 2212, the recessed area on the lens plate 270 that mates with it rotates from the third recessed portion 2713 to the second recessed portion 2712, and the depth dimension of the recessed area becomes smaller, resulting in a larger distance between the first inner ring 230 and the second inner ring 240. The elastic member 260 extends, and the lens plate 270 moves upward along the axial direction of the inner cylinder 110, and the distance between the lens plate 270 and the light source substrate 340 becomes larger. By means of the telescopic movement of the spring, the lens plate 270 moves axially within a small range along the inner cylinder 110, thereby changing the distance between the lens plate 270 and the light source substrate 340 and realizing the adjustment of the beam angle.

[0034] In this embodiment, a bump portion 231 is provided on the inner circumference and / or outer circumference of the first inner ring 230 and / or the second inner ring groove 240 for anti-rotation cooperation with the outer circumference of the inner cylinder 110 and / or the recessed groove 121 on the outer side wall of the inner ring groove 120. A recessed portion 311 is provided on the outer circumference of the first outer ring 310 and / or the second outer ring 320 for anti-rotation cooperation with the corresponding protruding portion 131 on the outer side wall of the outer ring groove 130.

[0035] Please refer to Figure 5 , Figure 5 is a schematic cross-sectional view of the waterproof ring of the lamp provided by the embodiment of the present invention. The inner ring waterproof ring 250 includes an inner ring wall 251 and a first inner connecting ring 252 and a second inner connecting ring 253 connected to both ends of the inner ring wall 251. The first inner connecting ring 252 cooperates with the bottom of the first inner ring 230, and the second inner connecting ring 253 cooperates with the top of the second inner ring 240. The inner ring wall 251 is located on the outer circumference of the first inner ring 230 and the second inner ring 240. A plurality of convex rings 254 are respectively provided on the inner and outer surfaces of the first inner connecting ring 252 and the second inner connecting ring 253. When multiple parts are press-fitted, the pressure causes the inner ring waterproof ring 250 to deform and result in gaps, and the convex rings 254 can prevent the generation of gaps. A groove 255 is provided on the inner surface of the first inner connecting ring 252 and the second inner connecting ring 253 close to the inner ring wall 251. The grooves 255 cooperate with the bosses 232 of the first inner ring 230 and the second inner ring 240 respectively, making it difficult for moisture to enter the light source substrate 340 through the bosses 232 and the grooves 255, thereby making the waterproof effect better.

[0036] The outer ring waterproof ring 330 includes an outer ring wall 331, a first outer connection ring 332 and a second outer connection ring 333 connected to both ends of the outer ring wall 331. The first outer connection ring 332 is matched with the bottom of the first outer ring 310, and the second outer connection ring 333 is matched with the top of the second outer ring 320. The outer ring wall 331 is located on the inner circumference of the first outer ring 310 and the second outer ring 320. Multiple convex rings 334 are respectively arranged on the upper and lower outer surfaces of the first outer connection ring 332 and the second outer connection ring 333. When multiple parts are press-fitted, the pressure causes the outer ring waterproof ring 330 to deform and result in gaps, and the convex rings 334 can well avoid the generation of gaps. Grooves 335 are arranged on the inner surfaces of the first outer connection ring 332 and the second outer connection ring 333 close to the outer ring wall 331. The grooves 335 are respectively matched with the bosses 323 of the first outer ring 310 and the second outer ring 320, making it difficult for moisture to enter the light source substrate 340 through the bosses 323 and the grooves 335, thereby making the waterproof effect better.

[0037] The lens plate 270 is pressed on the second inner connection ring 253 and the second outer connection ring 333 and fastened to the second inner ring 240 and the second outer ring 320 by screws. The first inner ring 230 and the first outer ring 310 are respectively fastened to the base 100, so that a sealed space is formed between the lens plate 270 and the base 100. Moisture cannot enter the light source substrate 340 through the first inner ring 230 and the second inner ring 240 from the middle part of the base 100, nor can it enter the light source substrate 340 through the first outer ring 310 and the second outer ring 320 from the side of the base 100, thus making the whole lamp 1 have a good waterproof effect. At the same time, the inner ring wall 251 of the inner ring waterproof ring 250 and the outer ring wall 331 of the outer ring waterproof ring 330 can be folded and stretched. When the lens plate 270 moves upward in the inner cylinder 110, the inner ring wall 251 and the outer ring wall 331 are stretched, and when the lens plate 270 moves downward in the inner cylinder 110, the inner ring wall 251 and the outer ring wall 331 are folded, so as to ensure the sealed waterproof effect of the inner ring waterproof ring 250 and the outer ring waterproof ring 330.

[0038] Please participate Figure 6 , Figure 6 is a schematic top view structure diagram of the lamp provided by the embodiment of the present invention. At least one rotating handle 222 is provided on the adjusting ring 220 to facilitate the user's rotation operation. The adjusting ring 220 is also provided with a lens angle 223, and the pressing cover 210 is also provided with a pointer 211. In this embodiment, the number of rotating handles is 4, and the lens angles 223 are 60°, 90°, and 110° respectively. Optionally, the number of rotating handles 222 can be set according to actual needs.

[0039] The lamp 1 further includes a driving power supply 400, and the driving power supply 400 is used to supply power to the LED lights on the light source substrate 340.

[0040] In summary, those skilled in the art can easily understand that the lamp 1 provided by the present invention is provided with a plurality of first adjusting portions 271 with gradually increasing sizes on the lens plate 270. The adjusting ring 220 is pressed on the lens plate 270 and is rotatably arranged relative to the inner cylinder 110 on the same horizontal plane. The adjusting ring 220 is provided with at least one second adjusting portion 221 that cooperates with the first adjusting portion 271. When the adjusting ring 220 rotates relative to the inner cylinder 110 on the same horizontal plane, the second adjusting portion 221 cooperates with the first adjusting portions 271 of different sizes, so that the lens plate 270 has different assembly heights relative to the base 100, thereby changing the incident angle of the light from the light source substrate 340 to the lens plate 270. After being refracted by the lens plate 270, the exit angle of the light from the light source substrate 340 also changes among 60°, 90°, and 110°. Thus, the same lamp 1 can achieve light output with three different beam angles through simple adjustment, greatly optimizing the on-site lighting effect, improving the flexibility of the application of the lamp 1, and improving the lighting experience of users. Moreover, by wrapping the upper and lower surfaces and the outer periphery of the first inner ring 230 and the second inner ring 240 with the inner ring waterproof ring 250, and wrapping the upper and lower surfaces and the inner periphery of the first outer ring 310 and the second outer ring 320 with the outer ring waterproof ring 330, the entire lamp 1 has better waterproof effect. At the same time, since the inner ring wall 251 of the inner ring waterproof ring 250 and the outer ring wall 331 of the outer ring waterproof ring 330 can be folded and stretched and deformed, when the lens plate 270 moves up and down along the inner cylinder 110, while ensuring the sealing and waterproof effect of the inner ring waterproof ring 250 and the outer ring waterproof ring 330, it will not affect the up and down movement of the lens plate 270.

[0041] The above is only the embodiment of the present invention, and it does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
