[0027] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] like Figure 1-7 As shown, this utility model provides an adjustable-angle LED lamp, including a heat sink body 1 and a light source module 2, and also includes an embedded limiting toothed disc 3 and a fastener 4;

[0029] Specifically, the heat sink body 1 is an aluminum heat sink housing. Each end of the heat sink has a circular mounting interface 15 for connecting the light source module 2. The outer circumferential edge of the circular mounting interface 15 has a first gear structure 16, which is an arc-shaped rack. In a preferred embodiment, the pitch of the arc-shaped rack is 1mm to ensure precise meshing with the front gear portion 31 of the embedded limiting gear 3. The diameter of the circular mounting interface 15 is adapted to the annular limiting portion 32 of the embedded limiting gear 3 to ensure smooth assembly while avoiding excessive gaps.

[0030] like Figure 1 , Figure 2As shown, a cavity 11 is formed on the back of the radiator body 1, in which a battery 12 and a controller 13 are installed. The controller 13 preferably has light control and time control functions. A sealing groove is provided at the opening of the cavity 11, and a cover plate sealing ring 14 is embedded in the sealing groove. A cover plate 17 covers the opening through a clamping assembly 6 consisting of a pressure plate and screws. The screws pass through the through holes 33 on the pressure plate and cover plate 17 and engage with the threaded holes 212 on the radiator body 1, causing the cover plate sealing ring 14 to be deformed under pressure, thereby sealing the cavity 11. This structure is easy to maintain and has good protective performance. The radiator body 1 is fixed to an external support such as a wall or column by a U-shaped mounting bracket 7. The installation angle of the U-shaped mounting bracket 7 can be adjusted by a fixing screw 71.

[0031] like Figure 1 As shown, this embodiment also includes a solar panel 5, which is fixed to the top of the radiator body 1 by another set of clamping components 6 consisting of a pressure plate and screws. The output end of the solar panel 5 is electrically connected to the battery 12, thereby realizing solar power supply.

[0032] like Figure 2 As shown, in this embodiment, the light source module 2 includes a light source heat sink 21, an LED light source board 22, a lens 23, and a glass cover 24. The light source heat sink 21 has a rectangular plate structure for heat dissipation of the LED light source board 22. Four limiting protrusions 211 are evenly distributed around the circumference of the light source heat sink 21, forming a limiting structure. A threaded hole 212 is formed at the center of the limiting structure of the light source heat sink 21 for screwing with the fastener 4. The LED light source board 22 is thermally bonded to the front surface of the light source heat sink 21 using thermally conductive silicone grease, and the LED light source board 22 is electrically connected to the controller 13 via wires. The lens 23 is disposed on the light-emitting side of the LED light source board 22 for secondary light distribution, controlling its light emission angle and light spot shape. An optical sealing ring 25 is provided above the lens 23, and a glass cover 24 is placed on top of it. The optical component is pressed and fixed to the light source heat sink 21 by a clamping assembly 6 consisting of another set of pressure plates and screws. The optical sealing ring 25 serves to seal and buffer.

[0033] like Figure 3 As shown, in this embodiment, the embedded limiting gear 3 includes a front gear 31 and an annular limiting part 32 arranged coaxially. The front gear 31 is a sector gear that meshes with the first gear structure 16, and its tooth pitch is also 1mm. This configuration makes the angle of each tooth rotation of the light source module 2 10 degrees.

[0034] The circular limiting part 32 is a cylindrical segment extending backward, and four limiting grooves 321 are provided on its circumferential inner wall. The limiting grooves 321 are adapted to the shape of the limiting protrusions 211 so that the limiting protrusions 211 can be embedded and engaged in the limiting grooves 321, thereby realizing the synchronous rotation of the light source module 2 and the embedded limiting toothed disk 3.

[0035] like Figure 1 , Figure 4 As shown, the fastener 4 is a hand screw. The hand screw passes through the through hole 33 in the center of the radiator body 1 and the through hole 33 in the center of the embedded limiting toothed plate 3 in sequence, and then screws into the threaded hole 212 of the light source radiator 21.

[0036] During assembly, such as Figure 5 , Figure 6 As shown, the circular limiting part 32 of the embedded limiting gear 3 is inserted into the circular mounting interface 15 of the heat sink body 1, so that the limiting protrusion 211 of the light source module 2 is embedded in the limiting groove 321 of the gear. Then, the hand screw is passed through the heat sink body 1 and the embedded limiting gear 3 in sequence, and screwed into the threaded hole 212 of the light source heat sink 21. Tightening the hand screw will fix it.

[0037] like Figure 7 As shown, when adjusting the angle, loosen the hand screw to separate the front gear plate 31 from the first gear structure 16, rotate the light source module 2 to the desired angle, and then tighten the hand screw to engage and fix the gear plate.

[0038] like Figure 5 , Figure 6 As shown, when switching the luminaire from floodlight mode to billboard lighting mode, completely unscrew the thumb screws and remove the embedded limiting gear 3 to separate the light source module 2 from the heat sink body 1. After reversing the left and right orientations of the light source module 2 and reinstalling and fixing it, the light output direction can be changed, thereby enabling the luminaire to quickly switch between different lighting scenarios.

[0039] Based on the above embodiments, this embodiment further incorporates a waterproof design, making it suitable for humid outdoor environments. Specifically, a silicone sealing ring is provided at the junction of the heat sink body 1 and the light source module 2; the lens 23 is connected to the light source heat sink 21 by multiple screws, thereby ensuring that the optical center of the lens 23 maintains a constant relative position with the LED light source board 22 mounted on the light source heat sink 21. An O-ring is provided at the cylindrical section of the embedded limiting toothed disc 3 and the circular mounting interface 15 of the heat sink body 1 to prevent moisture from entering the heat sink. A waterproof gasket is provided under the nut of the hand-tightening screw to ensure the sealing performance of the fastening point, making it suitable for humid outdoor environments.

[0040] The above is a description of an adjustable-angle LED lamp according to the present invention, which is used to help understand the present invention; however, the implementation of the present invention is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the principle of the present invention shall be considered as equivalent substitutions and shall be included within the protection scope of the present invention.
