[0022] The following further elaborates on the present utility model in conjunction with the drawings and specific embodiments. The following description is only exemplary and does not limit the protection scope of the present utility model.

[0023] It should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0024] Please refer to Figure 1 、 Figure 6 and Figure 5 , a module angle adjustment mechanism for an LED street lamp, comprising a fixing plate 1, a rotating plate 2, an adjusting plate 3, a light source module 6 and a lamp housing 7. On both sides of the inner edge of the lamp housing 7, 3 fixing plates 1 are respectively arranged and fixed correspondingly. On both sides of the inner edge of the lamp housing 7, the adjusting plates 3 are slidably installed. The adjusting plates 3 can slide along the direction parallel to both sides of the lamp housing 7. The rotating plate 2 is rotatably installed on the fixing plate 1, and the rotating plate 2 is rotatably and slidably installed on the adjusting plate 3. The light source module 6 is fixed on the rotating plate 3. The adjusting plate 3 is higher than the fixing plate 1 in the vertical direction.

[0025] Please refer to Figure 2 and Figure 5 , the rotating plate 2 includes a rotating piece 22 and a receiving piece 21 perpendicular to the rotating piece 22. A first fixing hole 23 is provided on the receiving piece 21. A rotating shaft through hole 24 and a waist-shaped through hole 25 are provided on the rotating piece 22. The rotating shaft through hole 24 is used to pass through the first rotating shaft 4, and the waist-shaped through hole 25 is used to pass through the second rotating shaft 5. Since the waist-shaped through hole 25 has a certain waist length, the second rotating shaft 5 can not only rotate in the waist-shaped through hole 25, but also slide back and forth; the fixing plate 1 includes a fixing piece 11 and a supporting piece 12 perpendicular to the fixing piece 11. A second fixing hole 13 is provided on the fixing piece 11, and a first rotating shaft fixing hole 14 is provided on the supporting piece 12; the adjusting plate 3 includes a transmission piece 31 and a driving piece 32 perpendicular to the transmission piece 31. A second rotating shaft fixing hole 33 is provided on the transmission piece 31. Both ends of the driving piece 32 are provided with hollowed-out sliding grooves 34, and a scale 35 is provided on the outer surface edge of the sliding grooves 34 for distinguishing the sliding position of the adjusting plate 3 relative to the lamp housing 7.

[0026] During installation, screws are used to fix the fixing piece 11 of the fixing plate 1 to one side edge inside the lamp housing 7 through the second fixing holes 13. The fixing pieces 11 are fixed facing each other at corresponding positions on both side edges inside the lamp housing 7. Two groups of support columns are respectively provided on both side edges inside the lamp housing 7, and screw holes are provided at the tops of the support columns. By hand-tightening the screw 8 through the sliding groove 34, the adjusting plate 3 can be slidably installed on the edge inside the lamp housing 7. Both ends of the light source module 6 are respectively fixed to the first fixing holes 23 of the corresponding receiving pieces 21 by screws, so that the light source module 6 is fixed inside the lamp housing 7. The rotating piece 22 is rotatably fixed in the first rotating shaft fixing hole 14 of the fixing plate 1 through the first rotating shaft 4, and the rotating piece 22 is rotatably and slidably installed on the second rotating shaft fixing hole 33 of the adjusting plate 3 through the second rotating shaft 5.

[0027] Since the positions of the fixing plate 1 and the lamp housing 7 are fixed, when the angle needs to be adjusted, loosen the hand-tightening screw 8 and slide the adjusting plate 3. The transmission piece 31 moves horizontally relative to the lamp housing 7. The transmission piece 31 slides and rotates with the rotating piece 22 through the second rotating shaft 5. The transmission piece 31 can drive the rotating piece 22 to rotate around the support piece 12, and then drive the angle change between the receiving piece 21 and the lamp housing 7, so as to realize the adjustment of the light-emitting angle of the LED street lamp.

[0028] The module angle adjustment mechanism provided by the present utility model can be connected to multiple light source modules 6 at the same time. Only by sliding the adjusting plate 3, the angle adjustment of multiple modules can be realized at the same time. It is particularly suitable for heavy-duty LED street lamps with multiple modules, which can save labor costs and improve work efficiency.

[0029] The above embodiments are only the preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present utility model should be covered within the protection scope of the present utility model.
