[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figure 1-8 This utility model provides a technical solution:

[0029] An LED street light fixture includes a light fixture assembly 1. A ventilation assembly 2 is fixedly connected to the upper end of the light fixture assembly 1, and a heat dissipation assembly 3 is fixedly connected to the lower end of the light fixture assembly 1. The ventilation assembly 2 includes a first spring telescopic rod 21. A fixed lug 22 is fixedly connected to the outer side of the first spring telescopic rod 21. A movable disc 23 is fixedly connected to one side of the fixed lug 22. A heat dissipation vent 24 is opened on the inner side of the movable disc 23. A rubber ring 25 is fixedly connected to the outer side of the movable disc 23. The heat dissipation assembly 3 includes a second spring telescopic rod 31. An impact plate 32 is fixedly connected to the top end of the second spring telescopic rod 31. A through hole 33 is opened on the inner side of the impact plate 32. A copper pipe 34 is fixedly connected to the top end of the impact plate 32. An air outlet 35 is opened on the inner side of the copper pipe 34. The outer side of the copper pipe 34 is inserted into the inner side of the heat dissipation vent 24.

[0030] As a further implementation of this solution, the lamp assembly 1 includes a lamp body 11, with a housing 12 fixedly connected to the inner side of the lamp body 11. A mesh plate is fixedly connected to the right end of the housing 12 by bolts. The right end of the housing 12 is a through structure, and the housing 12 communicates with the outer side of the lamp body 11. Through the above arrangement, the isolation of the housing 12 can reduce the heat generated by the drive motor 13 from entering the lamp body 11, and can dissipate heat from the drive motor 13 during operation.

[0031] As a further implementation of this solution, a shaft hole is provided at the left end of the housing 12. The inner side of the housing 12 is fixedly connected to the housing of the drive motor 13. The main shaft of the drive motor 13 rotates inside the shaft hole of the housing 12. An extension shaft 14 is fixedly connected to the end of the main shaft of the drive motor 13. The left end of the extension shaft 14 is rotatably connected to the inner side of the lamp body 11 through a bearing. A toggle block 15 is fixedly connected to the outer side of the extension shaft 14. A protrusion is fixed at the upper end of the toggle block 15. The toggle block 15 is located at the lower end of the impact plate 32. With the above arrangement, the stability of the extension shaft 14 when rotating can be improved. At the same time, the toggle block 15 can be driven to rotate. The impact plate 32 is moved by the push of the toggle block 15.

[0032] As a further implementation of this solution, a fixing groove 16 is provided through the upper end of the lamp body 11. The inner side of the fixing groove 16 is fixedly connected to the outer side of the rubber ring 25. A gap is provided between the outer side of the movable plate 23 and the inner side of the fixing groove 16. A gap is provided between the top end of the fixing ear 22 and the bottom end of the fixing groove 16. With the above settings, when the movable plate 23 vibrates, it can drive the rubber ring 25 to deform. The gap between the movable plate 23 and the fixing groove 16 provides space for the rubber ring 25 to deform. The gap between the fixing ear 22 and the fixing groove 16 provides space for the fixing ear 22 to move, thereby playing a role in repelling insects.

[0033] As a further implementation of this solution, the heat dissipation vents 24 penetrate the inner side of the movable plate 23 vertically. The inner side of the movable plate 23 is in contact with the outer side of the copper pipe 34. The number of heat dissipation vents 24 is the same as the number of copper pipes 34. The inner side of the copper pipe 34 is a hollow structure, and the lower end of the copper pipe 34 is a through structure. The inner side of the copper pipe 34 is connected to the through hole 33. The air outlet 35 is connected to the inner side of the copper pipe 34. The through hole 33 penetrates the inner side of the impact plate 32 vertically. There is a gap between the top of the impact plate 32 and the bottom of the fixed ear 22. The bottom of the second spring telescopic rod 31 is fixedly connected to the inner side of the lamp body 11, and the top of the first spring telescopic rod 21 is fixed to the inner side of the lamp body 11. Through the above settings, the hollow structure and through design realize the air circulation and effectively promote heat dissipation. The gap between the impact plate 32 and the fixed ear 22 is set so that the impact plate 32 can collide with the fixed ear 22 when it moves, thereby forcing the movable plate 23 to vibrate.

[0034] Workflow: To prevent insects from clogging the ventilation holes and to dissipate heat inside the lamp body 11, heat is generated inside the lamp body 11 during illumination, which easily attracts insects. After the lamp body 11 is lit, the drive motor 13 is started simultaneously. The drive motor 13 drives the extension shaft 14 and the actuating block 15 to rotate. After the protrusion at the upper end of the actuating block 15 contacts the impact plate 32, the actuating block 15 moves the impact plate 32 upward. The impact plate 32 moves the copper tube 34 upward at the same time. The copper tube 34 slides inside the heat dissipation vent 24. At this time, the impact plate 32 impacts the fixed ear 22. The impacted fixed ear 22 causes the movable plate 23 to vibrate. Insects on the upper part of the movable plate 23 will be dislodged from the movable plate 23 due to the vibration, thus repelling insects. At the same time, after the impact plate 32 impacts the fixed ear 22, the first spring telescopic rod 21 is activated. The first spring telescopic rod 21 remains in an elastic extended state during the contraction of the moving part, while maintaining a certain distance between the fixed ear 22 and the lamp body 11, providing space for the vibration of the movable plate 23. The rubber ring 25 will deform to a certain extent with the vibration of the movable plate 23. At the same time, when the protrusion of the actuating block 15 pushes the impact plate 32 to move upward, the impact plate 32 will drive the copper tube 34 to move upward. The copper tube 34 protrudes from the upper end of the heat dissipation vent 24, and the external air will exchange with the air inside the lamp body 11 through the air outlet 35, the inside of the copper tube 34 and the through hole 33, thereby achieving the effect of heat dissipation inside the lamp body 11. Through the above settings, the lamp can effectively repel insects away from the ventilation hole during operation, and prevent insects from entering the lamp and the ventilation hole, preventing insects from affecting the normal heat dissipation of the lamp body 11 and causing damage to the internal structure of the lamp body 11.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
