Description

Technical Field

[0001] The present invention relates to the field of lighting fixtures, and in particular to a system based on easy-to-maintain modular LED street lamps. Background Art

[0002] LED street lights are widely used on roads in my country and other countries due to their high brightness, long lifespan, and environmental friendliness. However, LED street lights are exposed to high heat from their light-emitting diodes and are exposed to wind, rain, sun, insects, and birds, which can shorten their lifespan. Therefore, regular maintenance is required.

[0003] Based on this, some people have proposed using drones to maintain or replace lighting modules of LED street lights, such as the airborne system for replacing modular lighting fixtures disclosed in the Chinese invention patent publication number CN110831856A and its family patent disclosure, and the easy-to-install lighting fixtures and installation devices disclosed in the Chinese invention patent publication number CN104471314A and its family patent disclosure.

[0004] However, the above solution still has the problem of being relatively complex as a whole, and requires the use of components such as electric drives, which have low reliability and high cost, and are not suitable for large-scale applications.

[0005] In summary, it is necessary to propose an LED street light system that can be promoted on a large scale to solve the problem that the existing drone-mounted modular LED street lights have complex structures and are not conducive to promotion. Summary of the Invention

When the combination of technical solutions results in contradictions or inability to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] See Figures 1 to 5 An embodiment of the system of the present invention based on an easy-to-maintain modular LED street lamp shown in the figure includes: a lighting module 2 and a socket module 1. The lighting module 2 includes a cover plate 20, a lighting part 21 disposed on the lower side of the cover plate 20, and locking parts 24 respectively disposed on both sides of the cover plate 20. At least one side edge of the lighting part 21 is configured as a first inclined surface 23 that inclines towards the center of the lighting part 21. A plurality of LED lamp beads 22 are arranged in an array at the bottom of the lighting part 21. A magnetic power connector 35 is further provided at the bottom of the cover plate 20. The magnetic power connector 35 is used for electrically connecting the plurality of LED lamp beads 22. The magnetic power connector 35 is disposed at the rear side of the lighting part 21.

[0029] The socket module 1 includes a mounting frame 11 and a transparent lamp cover 12 fixedly connected to the bottom of the mounting frame 11 and used for wrapping the lighting part 21. An inclined second inclined surface 15 is configured inside the mounting frame 11 for guiding and slidingly connecting with the first inclined surface 23. A magnetic power interface 14 for electrically connecting the magnetic power connector 35 is further provided on the mounting frame 11. The transparent lamp cover 12 and the mounting frame 11 together form a receiving cavity for receiving the lighting part 21.

[0030] By setting the socket module 1 as the mounting frame 11 and the transparent lamp cover 12 fixedly connected to the mounting frame 11 to wrap the lighting part 21 in the lighting module 2, compared with the existing solutions, not only is the structure simpler, without excessive moving components, reducing the complexity of the system and improving the reliability, but also the lighting part 21 is protected by the wrapping of the transparent lamp cover 12, improving the service life of the LED street lamp and increasing the reliability of maintenance.

[0031] In some preferred embodiments, the lighting module 2 can also be engaged with the socket module 1 by means of a drone 3. The drone 3 includes a grasping device for grasping or releasing the lighting module 2, and an opening and closing device 30 for opening or releasing the locking portion 24. Specifically, the grasping device can adopt any existing grasping device, such as a flexible grasping device or a jaw-type grasping device. Such structural variations still fall within the protection scope of the present invention and will not be elaborated herein.

[0032] Furthermore, a signal generator is provided on one side of the magnetic power interface 14. Correspondingly, a signal receiver for receiving the signal of the signal generator is provided on the drone 3. A camera is also provided on the drone 3, and the camera is disposed on one side of the bottom of the drone 3 and is arranged to avoid the opening and closing device 30.

[0033] When maintenance of the lighting module 2 is required, the drone 3 flies above the street lamp, grasps the lighting module 2 through the grasping device, and is initially aligned in position under the guidance of the signal generator. Then, the position is identified through the camera for secondary confirmation and alignment. Then, it descends to about 10 mm above the socket module 1, and the lighting device is released by opening the jaws through the opening and closing device 30. Under the action of the first inclined surface 23 and the second inclined surface 15, the lighting module 2 is guided to be connected to the socket module 1. Specifically, the signal generator and receiver can be any existing signal generator and receiver such as Bluetooth, ZigBee, infrared, etc.

[0034] The locking portion 24 includes a jaw that extends downward and can rotate elastically. When the lighting module 2 is engaged with the socket module 1, the jaw extends outside the edge of the mounting frame 11 and clamps the mounting frame 11. Specifically, the jaw is rotatably connected to the outside of the mounting frame 11 through a torsion spring hinge seat assembly, so that it has a tendency to rotate inward. A third inclined surface 242 is provided on the outer side of the bottom end of the jaw, and a barb 241 is provided above the third inclined surface 242. The third inclined surface 242 is provided to enable the jaw to be guided by the mounting frame 11 to open the jaw during the downward movement of the lighting device, and the barb is provided to clamp and fix the jaw and the mounting frame 11. By setting the above scheme, the engagement process between the lighting module 2 and the socket module 1 can be completely carried out by gravity, and the jaw is driven to be clamped and fixed under the action of gravity, so that no power component is required, the system complexity is reduced, and the system reliability is improved.

[0035] In some preferred embodiments, the opening and closing device 30 is used to drive the jaws to open, including a grasping part 32 arranged on both sides of the bottom of the drone 3. The grasping part 32 is used to drive the top of the jaws to move towards the center of the lighting module 2 so as to open the jaws; and a first driving mechanism 31 arranged at the center of the bottom of the drone 3, and the first driving mechanism 31 is drivingly connected to the grasping part 32. Specifically, the first driving mechanism 31 can be a motor, and the grasping part 32 includes a connecting rod 321 provided with an end hook-shaped engaging part. The hook-shaped engaging part is used to hook the top end of the jaw. The two grasping parts 32 approach each other under the driving of the motor, so as to drive the jaws to rotate outwards to open the jaws, and release the lighting module 2 and the socket module 1 from each other.

[0036] In some other preferred embodiments, a first magnetic body is provided on the inner side of the top of the jaw, and an electromagnet is provided on the corresponding grasping part 32. The grasping part 32 is used to abut against the inner side of the top of the jaw and magnetize the first magnetic body through the electromagnet to grasp the jaw. The first magnetic body can also be an iron sheet or other magnetic metal sheets. When it is necessary to open the jaws, the electromagnet is activated and grabs the top end of the jaw through the first magnetic body. Under the action of the first driving mechanism 31, the two grasping parts 32 approach each other, thereby opening the jaws.

[0037] In some preferred embodiments, the second inclined surface 15 is circumferentially arranged inside the mounting frame 11, and a second magnetic body is arranged on the second inclined surface 15. Correspondingly, the first inclined surface 23 is arranged around the lighting module 2, and a third magnetic body for adsorbing the second magnetic body is arranged on the first inclined surface 23 correspondingly. By arranging mutually attracting magnetic bodies on both the first inclined surface 23 and the second inclined surface 15, the guiding and positioning are realized by the attracting action between the magnetic bodies and the guiding action of the inclined surface, thereby improving the accuracy and stability of the lighting module 2 during the engagement process with the socket module 1.

[0038] In some preferred embodiments, a rubber ring is arranged on the upper surface of the mounting frame 11 around the transparent lamp cover 12 to improve the waterproof performance of the lighting part 21 and avoid short circuit.

[0039] In some preferred embodiments, the transparent lamp cover 12 is configured to have a semicircular cross section. In other embodiments, the cross section of the transparent lamp cover 12 can also be arcuate. Such a structural change still falls within the protection scope of the present invention. The transparent lamp cover 12 with an arc-shaped outer shape can also refract the light emitted by the LED lamp beads 22, thereby playing a role in light homogenization and improving the lighting effect.

[0040] In some preferred embodiments, a fixing plate 13 is further provided at the tail of the mounting frame 11. An LED driving circuit 16 is provided on the lower side of the fixing plate 13, and the magnetic power interface 14 is provided above the fixing plate 13. An air vent 171 is provided at the tail of the transparent lamp cover 12, and a fan 17 is provided in front of the air vent 171. By providing the fan 17, when the lighting module 2 is in a working state, it can be actively cooled by the fan 17, thereby increasing the service life of the LED lamp beads 22.

[0041] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
