[0025] See also Figure 1 , Figure 1 The embodiment of the present invention provides a lamp 1, which includes a base 100, an inner ring component 200, an outer ring component 300 and a driving power supply 400, wherein the inner ring component 200, the outer ring component 300 and the driving power supply 400 are all arranged in the base 100.

[0026] See also Figure 2 , Figure 2 The base 100 is provided with an inner cylinder 110 , an inner ring groove 120 and an outer ring groove 130 , and the inner ring groove 120 and the outer ring groove 130 are sequentially located on the outer circumference of the inner cylinder 110 .

[0027] The inner ring assembly 200 includes a gland 210 , an adjustment 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] The pressure cover 210 is fixed to the inner cylinder 110 and is pressed on the inner periphery of the adjustment 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 adjustment parts 271 of increasing sizes. The adjustment ring 220 is pressed on the lens plate 270 and is rotatably arranged on the same horizontal plane relative to the inner cylinder 110. The adjustment ring 220 is provided with at least one second adjustment part 221 that cooperates with the first adjustment part 271. When the adjustment ring 220 rotates on the same horizontal plane relative to the inner cylinder 110, the second adjustment part 221 cooperates with the first adjustment part 271 of different sizes so that the lens plate 270 has different assembly heights relative to the base 100.

[0029] See also Figure 3 , Figure 31 is a schematic cross-sectional view of a portion of the structure of a lamp provided in an embodiment of the present invention. The lamp 1 includes a light source substrate 340, which is disposed in the base 100 between the inner annular groove 120 and the outer annular groove 130. The first adjustment portion 271 may be a plurality of recessed areas with successively increasing depths, and the second adjustment portion 221 may be at least one convex block portion that cooperates with the recessed area of ​​the first adjustment portion 271, or the first adjustment portion 271 may be a plurality of convex blocks with successively increasing heights, and the second adjustment portion 221 may be at least one recessed area that cooperates with the convex block portion of the first adjustment 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 adjustment part 271 may be three, namely the first recessed area 2711, the second recessed area 2712, and the third recessed area 2713, wherein the depths of the first recessed area 2711, the second recessed area 2712, and the third recessed area 2713 increase sequentially; the second adjustment part 221 may be three, namely the first protrusion part 2211, the second protrusion part 2212, and the third protrusion part 2213, wherein the heights of the first protrusion part 2211, the second protrusion part 2212, and the third protrusion part 2213 increase sequentially. When the adjustment ring 220 rotates relative to the inner cylinder 110, for example, from the first protrusion portion 2211 to the second protrusion portion 2212, the recessed area on the lens plate 270 that matches it rotates from the first recessed portion 2711 to the second recessed portion 2712, and the depth of the recessed area increases. The corresponding assembly height of the lens plate 270 relative to the base 100 decreases, and the assembly height of the light source substrate 340 in the base 100 relative to the lens plate 270 also decreases. The incident angle of light from the light source substrate 340 passing through the lens plate 270 increases. After refraction by the lens plate 270, the emission angle of light from the light source substrate 340 also increases, and the emission angle of the light changes from 60° to 90°. On the contrary, if the third protrusion portion 2213 is rotated to the second protrusion portion 2212, the recessed area on the lens plate 270 that matches it is rotated from the third recessed area 2713 to the second recessed area 2712, the depth dimension of the recessed area becomes smaller, and the corresponding assembly height of the lens plate 270 relative to the base 100 becomes larger, and the assembly height of the light source substrate 340 relative to the lens plate 270 also becomes larger, and the incident angle of the light from the light source substrate 340 through the lens plate 270 becomes smaller. After refraction by the lens plate 270, the exit angle of the light source substrate 340 also becomes smaller, and the exit angle of the light changes from 110° to 90°, thereby realizing the change of the beam angle of the lamp 1 by simply rotating the adjustment ring 220.

[0030] Optionally, according to actual needs, through precise optical design, by changing the height and number of the recessed area or the protruding portion of the lens plate 270, or changing the optical properties (such as the refractive index) of the lens plate 270, the same lamp 1 can achieve light output with more beam angles.

[0031] Different from the prior art, the lamp 1 provided in the present application is provided with a plurality of first adjustment parts 271 of increasing sizes on the lens plate 270, the adjustment ring 220 is pressed on the lens plate 270 and is rotatably arranged on the same horizontal plane relative to the inner cylinder 110, the adjustment ring 220 is provided with at least one second adjustment part 221 cooperating with the first adjustment part 271, when the adjustment ring 220 rotates on the same horizontal plane relative to the inner cylinder 110, the second adjustment part 221 cooperates with the first adjustment part 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 of the light source substrate 340 incident on the lens plate 270, and after refraction by the lens plate 270, the exit angle of the light of the light source substrate 340 is also changed among 60°, 90°, and 110°, so that the same lamp 1 can achieve light output of 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 user's lighting experience.

[0032] See also Figure 4 , Figure 4 1 is a schematic diagram of the exploded structure of the waterproof part of the lamp provided in an embodiment of the present invention. The lamp 1 also 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 guide structure is provided between the first inner ring 230 and the second inner ring 240, and the elastic member 260 is a spring and is sleeved on the outer periphery of the guide structure. The elastic member 260 can apply a continuous upward force to the lens plate 270 to ensure that the lens plate 270 and the lamp beads on the light source substrate 340 are kept at a certain distance. 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 provided in the concave holes 241. The guide posts and guide sleeves 242 of the first inner ring 230 are aligned 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 recessed holes 321, and guide posts and guide sleeves 322 are provided in the recessed holes 321. The guide posts and guide sleeves 322 of the first outer ring 310 are aligned and inserted 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 recessed 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, so that the lens plate 270 can only make a small range of axial movement along the inner cylinder 110 through the expansion and contraction of the spring.

[0033] When the adjustment ring 220 rotates relative to the inner cylinder 110, for example, from the first protrusion portion 2211 to the second protrusion portion 2212, the matching recessed area on the lens plate 270 rotates from the first recessed portion 2711 to the second recessed portion 2712, and the depth dimension of the recessed area increases, resulting in a decrease in the 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. On the contrary, if the third protrusion 2213 is rotated to the second protrusion 2212, the concave area on the lens plate 270 that matches it is rotated from the third concave area 2713 to the second concave area 2712, and the depth of the concave area is reduced, resulting in a larger distance between the first inner ring 230 and the second inner ring 240, and the elastic member 260 is extended, 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 is increased. The lens plate 270 makes a small range of axial movement along the inner cylinder 110 through the expansion and contraction of the spring, 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, the inner and / or outer circumference of the first inner ring 230 and / or the second inner ring groove 240 is provided with a protrusion 231 for anti-rotation cooperation with the outer circumference of the inner cylinder 110 and / or the recessed groove 121 on the outer wall of the inner ring groove 120, and the outer circumference of the first outer ring 310 and / or the second outer ring 320 is provided with a recessed portion 311 for anti-rotation cooperation with the corresponding protrusion 131 on the outer wall of the outer ring groove 130.

[0035] See also Figure 5 , Figure 5 2 is a schematic cross-sectional view of the waterproof ring of the lamp provided by an 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 arm 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 at the outer periphery of the first inner ring 230 and the second inner ring 240. The inner and outer surfaces of the first inner connecting ring 252 and the second inner connecting ring 253 are respectively provided with a plurality of convex rings 254. When multiple parts are crimped and matched, the pressure causes the inner ring waterproof ring 250 to deform and cause gaps. The convex rings 254 can avoid 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 near the inner ring wall 251, and the groove 255 cooperates with the boss 232 of the first inner ring ring 230 and the second inner ring ring 240 respectively, making it difficult for moisture to enter the light source substrate 340 through the boss 232 and the groove 255, thereby improving the waterproof effect.

[0036] The outer ring waterproof ring 330 includes an outer ring wall 331 and a first outer connecting ring 332 and a second outer connecting ring 333 connected to both ends of the outer ring arm 331. The first outer connecting ring 332 matches the bottom of the first outer ring 310, and the second outer connecting ring 333 matches the top of the second outer ring 320. The outer ring wall 331 is located at the inner periphery of the first outer ring 310 and the second outer ring 320. The upper and lower outer surfaces of the first outer connecting ring 332 and the second outer connecting ring 333 are respectively provided with a plurality of convex rings 334. When multiple parts are crimped and matched, the pressure causes the outer ring waterproof ring 330 to deform and cause gaps. The convex rings 334 can well avoid the generation of gaps. A groove 335 is provided on the inner surface of the first outer connecting ring 332 and the second outer connecting ring 333 near the outer ring wall 331, and the groove 335 cooperates with the boss 323 of the first outer ring ring 310 and the second outer ring ring 320 respectively, making it difficult for moisture to enter the light source substrate 340 through the boss 323 and the groove 335, thereby improving the waterproof effect.

[0037] The lens plate 270 is pressed onto the second inner connecting ring 253 and the second outer connecting ring 333 and is 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 fastened to the base 100 respectively, so that the lens plate 270 and the base 100 form a sealed space. Moisture cannot enter the light source substrate 340 from the middle part of the base 100 through the first inner ring 230 and the second inner ring 240, nor can it enter the light source substrate 340 from the side of the base 100 through the first outer ring 310 and the second outer ring 320, so that the entire lamp 1 has 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 are foldable and stretchable. 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 deformed. 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 and deformed, thereby ensuring the sealing and waterproof effect of the inner ring waterproof ring 250 and the outer ring waterproof ring 330.

[0038] Please participate Figure 6 , Figure 6 2 is a schematic diagram of a top view of a lamp provided in an embodiment of the present invention. The adjusting ring 220 is provided with at least one rotating handle 222 for the user to perform a rotating operation. The adjusting ring 220 is also provided with a lens angle 223. The pressure 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 , which is used to supply power to the LED lamp on the light source substrate 340 .

[0040] In summary, it is easy for those skilled in the art to understand that the lamp 1 provided by the present invention is provided with a plurality of first adjustment parts 271 of increasing sizes on the lens plate 270, the adjustment ring 220 is pressed on the lens plate 270 and is rotatably arranged on the same horizontal plane relative to the inner cylinder 110, the adjustment ring 220 is provided with at least one second adjustment part 221 that cooperates with the first adjustment part 271, and when the adjustment ring 220 rotates on the same horizontal plane relative to the inner cylinder 110, the second adjustment part 221 cooperates with the first adjustment part 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 of the light source substrate 340 incident on the lens plate 270, and after refraction by the lens plate 270, the exit angle of the light of the light source substrate 340 is also changed among 60°, 90°, and 110°, so that the same lamp 1 can achieve light output of three different beam angles through simple adjustment, which greatly optimizes the on-site lighting effect, improves the flexibility of the application of the lamp 1, and improves the lighting experience of the user. Moreover, the inner ring waterproof ring 250 wraps the upper and lower surfaces and the outer periphery of the first inner ring 230 and the second inner ring 240, and the outer ring waterproof ring 330 wraps the upper and lower surfaces and the inner periphery of the first outer ring 310 and the second outer ring 320, so that the entire lamp 1 has a 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 are foldable and stretchable, it is ensured that when the lens plate 270 moves up and down along the inner cylinder 110, the inner ring waterproof ring 250 and the outer ring waterproof ring 330 ensure the sealing and waterproof effect, while not affecting the up and down movement of the lens plate 270.
