[0001] The invention belongs to the technical field of lighting equipment, and in particular relates to an underwater LED lighting device. Background Art

[0002] Underwater LED lighting is an underwater lighting that uses LED as a light source, usually with a mixed color of red, green and blue. Underwater LED lighting is usually installed below the water surface of fountains, pools and park lakes to achieve the effect of lighting and beautification.

[0003] For example, Chinese invention CN221258743U discloses an underwater LED lamp, including a shell, an intermediate seat and a lamp holder. The lamp holder is driven by two motors inside the shell to revolve and rotate, so that the light can be adjusted within a circular arc area in space.

[0004] However, after long-term use, foreign matter will accumulate on the surface of the lampshade of existing underwater LED lamps, especially underwater LED lamps used in parks and lakes. Foreign matter is very likely to accumulate on the surface of the lampshade, which will seriously affect the overall lighting effect. If it is not cleaned, the foreign matter will increase with the increase of usage time, and the lighting effect will become worse and worse. Since the existing underwater LED lamps are underwater, it is very inconvenient to clean the lampshades, resulting in poor reliability and lighting effect of the underwater LED lamps after long-term use.

Detailed implementation manner

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0033] Please refer to Figures 1 to 3 As shown, the present invention is an underwater LED lighting device, including a base 1 and a lamp shade 2. The lower end of the lamp shade 2 has a right-angled flanging, which is fixedly connected to the upper surface of the base 1 by screws, and a sealing ring 101 is installed between the connection surfaces of the base 1 and the lamp shade 2. The base 1 is connected to a lamp holder for installing LED lamp beads.

[0034] The upper end of the lamp shade 2 is in a hemispherical structure. Two rotating shaft sleeves 201 are rotatably connected to the outer wall of the lamp shade 2. The two rotating shaft sleeves 201 are located in the same diameter direction of the hemispherical structure, and an arc plate 202 is fixedly connected between the two rotating shaft sleeves 201.

[0035] Specifically, for example, two symmetrically arranged connecting columns are integrally formed on the outer wall of the lamp shade 2, and the rotating shaft sleeve 201 is rotatably connected to the connecting column. The arc plate 202 is concentric with the hemispherical structure of the lamp shade 2, and the arc plate 202 is connected with a scraping strip 203 that fits the outer wall of the hemispherical structure of the lamp shade 2.

[0036] One of the rotating shaft sleeves 201 is fixedly connected with a driven wheel 204, and the driven wheel 204 is drivingly connected with a driving assembly for driving the rotating shaft sleeve 201 to rotate through the driving assembly, and driving the arc-shaped plate 202 to rotate around the upper end of the lamp cover 2, so as to realize the cleaning of the outer wall of the lamp cover 2 by the scraping strip 203. After the arc-shaped plate 202 rotates from one side of the lamp cover 2 to the other side, the rotating shaft sleeve 201 is driven to reverse by the driving assembly, so as to realize the rotation reset of the arc-shaped plate 202 and perform secondary cleaning on the surface of the lamp cover 2 through the scraping strip 203.

[0037] In a preferred embodiment of this embodiment, the driving assembly includes a rotating ring 3, and the rotating ring 3 is rotatably connected to the lamp cover 2. The rotating ring 3 is fixedly connected with an arc-shaped rack 301 meshing with the driven wheel 204 for driving the rotating shaft sleeve 201 to rotate by the rotation of the rotating ring 3 and the meshing of the arc-shaped rack 301 and the driven wheel 204.

[0038] Wherein, each time the arc-shaped rack 301 and the driven wheel 204 are separated from meshing, the arc-shaped rack 301 drives the driven wheel 204 to rotate 180°, that is, the arc-shaped plate 202 is driven by the rotating shaft sleeve 20 to rotate from one side of the lamp cover 2 to the other side.

[0039] At the same time, both rotating shaft sleeves 201 are fixedly connected with driven wheels 204, so that after the rotating ring 3 is separated from the driven wheel 204 on one side, it rotates to the other side of the lamp cover 2. When the arc-shaped rack 301 meshes with the other driven wheel 204, the rotation of the rotating ring 3 causes the rotating shaft sleeve 201 to rotate in the reverse direction, so that the arc-shaped plate 202 rotates in the reverse direction and resets. That is, by rotating the rotating ring 3 one circle, the reciprocating rotation of the arc-shaped plate 202 is completed to clean both sides of the lamp cover 2, thereby improving the cleaning efficiency.

[0040] Furthermore, the number of arc-shaped racks 301 is multiple, and the rotating ring 3 and the arc-shaped rack 301 can be integrally formed structures, such as made of nylon material. For example, the number of arc-shaped racks 301 shown in the figure is three, and only one of the driven wheels 204 meshes with the arc-shaped rack 301 at the same time. By increasing the number of arc-shaped racks 301, the number of reciprocating rotations of the arc-shaped plate 202 driven by the rotation of the rotating ring 3 is increased, and thus the cleaning effect is further improved.

[0041] As another preferred embodiment, as Figures 4 to 7As shown in the figure, the driving assembly includes a driving motor 4 and a driving ring 5. The driving motor 4 is fixedly connected to the base 1, and the driving ring 5 is rotatably connected to the base 1. Both the driving motor 4 and the driving ring 5 are located inside the lamp cover 2. The driving motor 4 and the driving ring 5 are in transmission connection. For example, a ring gear 502 is connected to the surface of the driving ring 5, and a gear 401 meshing with the ring gear 502 is connected to the output shaft of the driving motor 4. Thus, the ring gear 502 is driven by the gear 401, and then the driving ring 5 is driven to rotate.

[0042] A plurality of first permanent magnets 501 are evenly distributed on the circumference of the surface of the driving ring 5. The rotating ring 3 is connected with second permanent magnets 302 that correspond to the first permanent magnets 501 one by one and attract each other. Thus, the driving ring 5 drives the rotating ring 3 to rotate by magnetic force coupling. The driving ring 5 and the rotating ring 3 are located on the inner and outer sides of the lamp cover 2 respectively, so that the driving motor 4 and the driving ring 5 are in a sealed environment, which not only ensures the reliability of the driving motor 4 during use, but also avoids the process of requiring additional sealing treatment for the driving motor 4.

[0043] In addition, an annular mounting groove 303 is formed in the rotating ring 3, and the second permanent magnets 302 are evenly distributed in the annular mounting groove 303, so that the rotating ring 3 can be close to the lamp cover 2, which is beneficial to reducing the overall volume. An annular groove 205 is formed in the inner wall of the lamp cover 2, and the upper side of the first permanent magnet 501 is located in the annular groove 205, which is used to reduce the distance between the first permanent magnet 501 and the second permanent magnet 302, so that the first permanent magnet 501 can be closer to the second permanent magnet 302, improving the magnetic force coupling effect between them, and further ensuring the reliability and stability of the overall use.
