[0028] The control box 21 is located on the lower surface of the lamp housing 10, which is the light-emitting surface of the light source module 11 on the lamp body 1. The control box 21 is located on the lower surface of the lamp housing 10, and the lamp housing 10 can serve as a rain shield, thereby preventing rainwater from flowing into the control box 21.

[0029] The lamp housing 10 is provided with a connecting bracket 12. The first end of the control box 21 is inserted into the connecting bracket 12. The second end of the control box 21 is fixedly connected to the lamp housing 10 by fastening screws. The second end is the end opposite to the first end. In this embodiment, the first end is the left end of the control box 21 and the second end is the right end of the control box 21.

[0030] The first end of the control box 21 is provided with a first lug 26, and the control box 21 is inserted into the connecting bracket 12 through the first lug 26. The second end of the control box 21 is provided with a second lug 23, and a fastening screw is provided on the second lug 23. A first connecting member 231 is provided between the first lug 26 and the lamp housing 10 to allow the first lug 26 and the lamp housing 10 to be detachably engaged. In this application, the first connecting member 231 is a screw, and the second lug 23 is directly fixed to the lamp housing 10 by the screw. In addition to the screw, any other connecting member that can fix the second lug 23 to the lamp housing 10 can be used instead. Preferably, in this application, screws and wing nuts are used to fix the control box 21 to the lamp housing 10. When disassembly is required, the wing nut can be turned manually. Disassembly and assembly do not require tools and are more convenient. The lamp housing 10 is provided with a connecting bracket 12, and a slot 121 for the first lug 26 to be inserted is formed between the connecting bracket 12 and the lamp housing 10. The slot 121 serves to position and limit.

[0031] When the control box 21 needs to be disassembled, the first connector 231 can be removed manually, so that the second lug 23 is disengaged from the lamp body 1. Then, the control box 21 can be pulled out from left to right, so that the first lug 26 can be removed from the slot 121. This eliminates the need to disassemble the lamp body 1, making disassembly faster. Furthermore, during maintenance, only the control box 21 needs to be repaired or replaced. Maintenance can be carried out directly at high altitudes, making maintenance more efficient and greatly reducing the time spent on the road.

[0032] Furthermore, the light source module 11 can be an international lens module or a die-cast module, and the lamp housing 10 is also equipped with a photovoltaic panel. In addition, through the glass + lens module, it can be transformed into a double-sided solar panel, increasing the solar energy utilization rate by %.

[0033] Preferably, the lamp body 1 also includes a support plate 101 installed inside the lamp housing 10, the control box 21 is detachably installed on the support plate 101, and the connecting bracket 12 is also installed on the support plate 101.

[0034] In this application, the control box 21 and the light source module 11 are located on the same side. In addition to being installed on the same side, the control box 21 and the light source module 11 can also be installed in other different locations.

[0035] The control box 21 is also provided with a third lug 24, which has a buckle hole. A safety buckle 25 is connected to the buckle hole of the third lug 24. A safety rope 251 is connected between the safety buckle 25 and the lamp housing 10 or the support plate 101. The safety rope 251 is always connected to the lamp housing 10 or the support plate 101. The safety buckle 25 can improve safety and prevent the control box 21 from falling.

[0036] The control box 21 is equipped with a sensor 22. Inside the control box 21 is a controller (not shown in the figure) that is electrically connected to the sensor 22, the light source module 11 and the power supply 28. The sensor 22 identifies whether someone is passing by and then transmits the signal to the controller. The controller then activates the light source module 11, thereby enabling the light to turn on only when someone passes by. Therefore, when no one is passing by, the light source module 11 is in the off state, making the street light of this application more energy-efficient.

[0037] The light source module 11 is connected to a power cord 14, and the end of the power cord 14 is provided with a plug 141. The control box 21 is provided with a socket 27 that is installed in conjunction with the plug 141. The lamp housing 10 or the support plate 101 is provided with a wire hole (not shown in the figure) that is in conjunction with the power cord 14. A protective coil 13 is provided in the wire hole, and the power cord 14 passes through the protective coil 13. The outer periphery of the protective coil 13 is sealed with the lamp housing 10 or the support plate 101. The protective coil 13 is also sealed with the power cord 14, thereby improving waterproofness. In addition, the power cord 14 is short, which can greatly reduce line loss. The use of aviation DC gold-plated plug connectors can reduce wire connection errors.

[0038] The control box 21 is detachably equipped with a cover 211, and a seal 29 is installed between the cover 211 and the box body. Through the sealing cooperation between the seal 29 and the protective coil 13, the protection level of the street light and the control box 21 reaches IP.

[0039] A bracket 4 is installed on the lamp housing 10, and a receiving space 41 for placing the control box 21 is formed between the bracket 4 and the lamp housing 10.

[0040] A mounting base 31 is installed on the bracket 4. The mounting base 31 is hinged to a handle 33 via a second connector 32. The handle 33 is used to connect with the lamp post. Preferably, the handle 33 is connected with several set screws for abutting and engaging with the lamp post.

[0041] When it is necessary to adjust the angle between the handle 33 and the lamp body 1, the second connecting member 32 is adjusted to make the fixed base 31 and the handle 33 a movable fit, so that the handle 33 can rotate around the axis of the second connecting member 32. When the desired angle is reached, the second connecting member 32 is simply adjusted in the opposite direction to make the fixed base 31 and the handle 33 a fixed fit, thereby fixing the angle between the handle 33 and the lamp body 1, and thus adjusting the angle between the lamp body 1 and the ground.

[0042] Example 2 differs from the above examples in that:

[0043] Reference Appendix Figure 6-7 In this embodiment, an adjustable support assembly is provided between the outer peripheral wall of the handle 33 and the bracket 4. The support assembly includes an adjusting rod 35 and a connecting cylinder 36. The connecting cylinder 36 is slidably sleeved on the outer periphery of the adjusting rod 35. The adjusting rod 35 and the connecting cylinder 36 are respectively hinged to the handle 33 and the bracket 4. In this application, the connecting cylinder 36 is hinged to the bracket 4, and the adjusting rod 35 is hinged to the handle 33. In addition to the above connection relationship, the connecting cylinder 36 can also be hinged to the handle 33, and the adjusting rod 35 can be hinged to the bracket 4. A pin is provided on the connecting cylinder 36, and a plurality of adjusting holes that cooperate with the pin are provided along the length direction of the adjusting rod 35.

[0044] The fixed base 31 has an arc-shaped groove 34. A third connector 37 is also connected between the fixed base 31 and the handle 33. The third connector 37 is slidably disposed in the arc-shaped groove 34. The cooperation between the arc-shaped groove 34 and the third connector 37 plays a guiding and supporting role. The center of the arc-shaped groove 34 is located on the axis of the second connector 32.

[0045] When it is necessary to adjust the angle between the handle 33 and the lamp body 1, the second connector 32 and the third connector 37 are adjusted to make the fixed base 31 and the handle 33 a movable fit, so that the handle 33 can rotate around the axis of the second connector 32 and the third connector 37 slides in the arc groove 34. When the desired angle is reached, the second connector 32 and the third connector 37 are simply adjusted in the opposite direction to make the fixed base 31 and the handle 33 a fixed fit, thereby fixing the angle between the handle 33 and the lamp body 1, and thus adjusting the angle between the lamp body 1 and the ground.

[0046] In this application, the second connector 32 and the third connector 37 are both screws and nuts. The above functions are achieved by adjusting the screw fit. In addition to screw and nut connection, the handle locking part mentioned in Chinese invention patent (application publication number: CN107651057A) can also be used instead. In addition to the above two connectors, any other structure that can achieve the above functions can also be used instead.
