[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Please see the attached Figures 1 to 5 As shown, an LED wall washer lamp in an embodiment of the present invention includes a housing 1, wherein a first cavity 5, a second cavity 6, and a third cavity 7 are provided inside the housing 1. The two first cavities 5 are respectively provided on both sides of the second cavity 6, and the second cavity 6 is provided on the lower side of the first cavity 5.

[0029] Among them, the inner bottom of the second cavity 6 is fixedly connected with an LED light board 8, which provides lighting function through the light emitted by the LED light board 8.

[0030] The interiors of the two first cavities 5 are symmetrically and slidingly connected with sunshades 3, the upper ends of the sunshades 3 extend out of the outer end of the shell 1, the sunshades 3 include an arc-shaped plate 31, and a friction pad 32 is fixedly connected at the middle of the outer surface of the arc-shaped plate 31; the interiors of the two first cavities 5 are symmetrically provided with driving components 9, which can drive the sunshades 3 to move, and after the two sunshades 3 are partially extended, the light emitted by the LED light board 8 can be blocked. The two driving components 9 are independently provided and can individually control the degree of expansion of the two sunshades 3, so as to obtain different lighting effects, thereby meeting different personalized lighting needs, and are highly flexible to use. At the same time, the two sunshades 3 can be retracted into the shell 1, and after being retracted, they will not affect the normal lighting of the LED light board 8.

[0031] Specifically, the drive assembly 9 includes a worm 91, a friction wheel 92, a worm gear 93, and a motor 94. The worm 91 rotates inside the first cavity 5, the friction wheel 92 and the worm gear 93 are fixed to each other and rotate inside the first cavity 5, the worm 91 is meshed with the worm gear 93, the friction wheel 92 is in friction contact with the friction pad 32, and the motor 94 is fixed inside the first cavity 5 and the output end is fixedly connected to the worm 91. When the drive assembly 9 is in use, the motor 94 drives the worm 91 to rotate, the worm 91 drives the worm gear 93 to rotate, and then drives the friction wheel 92 to rotate, and the friction force between the friction wheel 92 and the friction pad 32 drives the sunshade 3 to move, wherein the drive structure of the worm gear 93 and the worm 91 has a self-locking ability, which can meet the locking requirements of the sunshade 3 after adjustment.

[0032] Moreover, the two driving components 9 are independently arranged, and can independently drive the sunshade 3 connected thereto. When in use, the two driving components 9 can be started at the same time to adjust the two sunshades 3 synchronously and symmetrically, or only one driving component 9 can be started for differentiated adjustment, thereby obtaining a more flexible and changeable lighting effect, which can meet different personalized lighting needs.

[0033] In addition, in order to ensure that the arc plate 31 can move stably, sliding rings 33 are fixedly connected on both sides of the outer surface of the arc plate 31, and arc sleeves 13 are fixedly connected on both sides of the interior of the first cavity 5. The sliding ring 33 is slidably connected to the arc sleeve 13. When the arc plate 31 moves, the sliding ring 33 is guided by the arc sleeve 13, thereby ensuring that the arc plate 31 can be stably and smoothly unfolded and retracted.

[0034] Arc-shaped receiving cavities 11 are provided on both sides of the interior of the third cavity 7. The curvature of the arc-shaped receiving cavity 11 is the same as that of the arc-shaped plate 31. The arc-shaped plate 31 can extend into the arc-shaped receiving cavity 11. By setting the arc-shaped receiving cavity 11, the arc-shaped plate 31 will not be interfered with when it is received.

[0035] A plurality of mounting holes 12 are formed on the lower end surface of the third cavity 7 , and the mounting holes 12 are provided to facilitate the installation and fixation of the housing 1 .

[0036] In this embodiment, a plurality of heat dissipation fins 10 are fixed to the outer wall of the second cavity 6, and a glass panel 2 is clamped on the inner upper end of the second cavity 6. When the LED light board 8 is working, heat is generated. In order to dissipate heat, the heat dissipation fins 10 provided can increase the surface area and improve the heat exchange effect with the air, thereby improving the heat dissipation effect and preventing the LED light board 8 from overheating. The provided glass panel 2 has high transparency and does not affect the light. At the same time, it can also protect the internal LED light board 8. Among them, the glass panel 2 can be made of tempered glass. The strength of tempered glass is high and it is more reliable when used outdoors.

[0037] The arc-shaped plate 31 is made of opaque plastic, and the outer ends of the two arc-shaped plates 31 that contact each other are covered with rubber pads. The arc-shaped plate 31 made of opaque plastic is light in weight, has good strength, and has a strong light-blocking effect. Among them, the arc-shaped plate 31 can be made of black plastic. The black color has strong light absorption and can further improve the light-blocking effect. The rubber pad can play a buffering role when the two arc-shaped plates 31 are completely closed. At the same time, the rubber pad has good elasticity and can also reduce the gap after closing.

[0038] Both ends of the housing 1 are fixedly connected with cover plates 4 by screws. The cover plates 4 are used to close the ends of the housing 1, and through holes are opened on the cover plates 4 to facilitate the connection of wires for electricity.

[0039] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
