Description

Technical Field

[0001] This invention relates to the field of folding lighting technology, and more particularly to a foldable multi-faceted LED lighting lamp. Background Technology

[0002] LED lighting is a new type of lighting device that uses light-emitting diodes as the core light-emitting element and directly converts electrical energy into light energy to achieve lighting function. Compared with traditional incandescent lamps and fluorescent lamps, LED lighting has significant features such as compact structure, high energy efficiency, and long life. It is the mainstream product in the current lighting field and is widely used in home, commercial, industrial, and outdoor scenarios.

[0003] Foldable multi-faceted LED lights are a new type of lighting device that achieves folding functionality through the hinged or sliding connection of multiple LED panels. This design not only saves storage space but also allows for diverse lighting effects by adjusting the size and angle of the panels.

[0004] Existing foldable multi-faceted LED lights generally use wires to power each LED panel. When the LED panel is unfolded, the wires coiled inside the lamp body are straightened to maintain power supply; when the panel is folded, the wires coil back up. Therefore, during the unfolding and folding of the LED panel, the wires inevitably rub against the surrounding housing structure. After long-term use, the wire sheaths will gradually wear down and crack due to repeated friction, shortening the device's lifespan. Simultaneously, the friction between the wires and the housing will create resistance when the panel pulls the wires, which will translate into additional pulling force concentrated at the connection points between the wires and the panel. This can lead to loose terminals, solder joint detachment, or even direct wire breakage at the connection point, causing a power outage malfunction for the panel.

[0005] Furthermore, if the LED panel needs to be expanded to a large area, a longer amount of wire redundancy must be reserved to accommodate the panel's expansion stroke. The increase in redundancy will further amplify the above problems and make the wires more prone to tangling or squeezing when coiled, increasing the risk of circuit damage. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that in traditional foldable multi-faceted LED lights, the wires connected to the LED panel are easily worn by friction with the surrounding housing during unfolding and folding, which increases the tension at the connection point between the wires and the panel, causing the terminals to loosen and the solder joints to fall off. Therefore, this invention proposes a foldable multi-faceted LED light.

[0007] To achieve the above objectives, the present invention employs the following technology: a foldable multi-faceted LED lighting lamp comprising a housing, wherein a main LED panel is fixedly installed inside the housing, two sets of sliding rods are slidably connected inside the housing, and a secondary LED panel is rotatably connected between each set of sliding rods; a wire is connected to one side of the secondary LED panel; and further comprising:

[0008] The wire control mechanism includes a mounting shell fixed inside the housing, with a first gear rotatably connected to both ends of the mounting shell, a first toothed rod meshing with the first gear at one end of the slide rod, a core rod fixed to one side of the first gear, a winding cylinder slidably sleeved on the outside of the core rod, and a wire laying assembly at one end of the winding cylinder.

[0009] When the secondary LED panel is unfolded or folded, the winding drum releases or winds the wires by rotating clockwise or counterclockwise. At the same time, the wire assembly drives the winding drum to move axially, so that the wires are released or wound in an orderly manner on the winding drum.

[0010] As a further description of the above-mentioned foldable multi-faceted LED lighting lamp: the wiring assembly includes a threaded post fixed to one end of the winding cylinder, a screw cylinder threadedly connected to the threaded post is fixed inside the mounting housing, and a positioning sleeve is fixed inside the mounting housing.

[0011] As a further description of the above-mentioned foldable multi-faceted LED lighting lamp: the release or winding speed of the wire is always synchronized with the displacement speed of the sub-LED panel, and the number of wire layers on the winding drum does not exceed a single layer.

[0012] As a further description of the above-mentioned foldable multi-faceted LED lighting lamp: a controller is installed inside the mounting housing, and a connection unit and a power connection unit are provided between the controller and the wires.

[0013] As a further description of the above-mentioned foldable multi-faceted LED lighting lamp: the connecting unit includes a limiting cylinder fixed inside the mounting housing, and the limiting cylinder has a slider rotatably connected to the end of a threaded column.

[0014] As a further description of the above-mentioned foldable multi-faceted LED lighting lamp: the power connection unit includes a male head fixed inside the slider, and a female connector electrically connected to the controller is fixed inside the mounting housing.

[0015] As a further description of the above-mentioned foldable multi-faceted LED lighting lamp: the wire is wound around the winding spool and passes through the inside of the threaded post, and the wire and the male end are electrically connected by a conductive slip ring.

[0016] As a further description of the above-mentioned foldable multi-faceted LED lighting lamp, it also includes an additional structure, which includes a second gear fixed to the rotating shaft of the sub-LED panel, one end of the first gear is fixed to the second gear, and the second gear is slidably connected inside the slide bar and meshes with the second gear.

[0017] In summary, the beneficial effects of this invention, which employs the aforementioned technology to create a foldable, multi-faceted LED lighting lamp, are as follows:

[0018] 1. This application uses a wire control mechanism to link the unfolding and folding actions of the wire and the secondary LED panel. When unfolding, the winding drum rotates forward to release the wire, and when folding, it rotates in the opposite direction to wind the wire, keeping the wire straight at all times. This avoids contact and friction damage with surrounding objects and prevents the connection between the wire and the secondary LED panel from loosening and breaking due to increased tension. At the same time, the wire assembly, through the cooperation of the threaded column and the screw cylinder, drives the winding drum to move axially synchronously when winding the wire. Combined with the limiting effect of the positioning sleeve, it realizes the orderly winding and release of the wire in a single layer, avoiding the squeezing and friction caused by local stacking of the wire, further protecting the wire and extending its service life. This advantage is even more prominent when the secondary LED panel needs to be unfolded over a large area and the wire needs to have a longer redundancy.

[0019] The wire control mechanism's wire take-up and take-down speed is matched with the folding and unfolding speed of the secondary LED panel, which keeps the wire straight and prevents pulling and slack during the folding and unfolding of the secondary LED panel, thus extending the wire's lifespan. In addition, this design can significantly reduce the change in the reverse force on the secondary LED panel when the wire is taken up and taken down, making the movement of the secondary LED panel smooth when unfolding and folding, and improving the operating feel.

[0020] 2. Through the cooperation of the power connection unit and the conductive slip ring, when the secondary LED panel is folded, the winding drum drives the threaded column to move downward, which in turn pushes the slider and the male end to move downward, so that the male end is separated from the female end, disconnecting the secondary LED panel circuit. This prevents the secondary LED panel from being accidentally turned on and wasting power when folded and stored, and also reduces the risk of electric shock during manual operation. In addition, when the secondary LED panel is folded, it is disconnected from the controller, and only the main LED panel is powered by the controller. If the main LED panel circuit fails, the secondary LED panel circuit remains in a safe state because it is not powered, avoiding the chain reaction of faults and reducing the overall maintenance cost.

[0021] 3. After unfolding, the secondary LED panel can deflect towards the main LED panel. When deflected, it drives the second gear to rotate, which in turn pulls the first gear through the second rack, thereby driving the first gear, core rod and winding drum to rotate. Simultaneously, it releases the wire of appropriate length, avoiding the wire from being stretched or bent due to insufficient length. At the same time, the friction between the second gear and the first rack, and the friction between the threaded column and the screw drum, make the secondary LED panel need to overcome a certain resistance when adjusting the angle. It can be stably stopped at the target angle without the need for an additional locking structure, adapting to diverse lighting needs. Attached Figure Description

[0037] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a foldable multi-faceted LED lighting lamp according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1-10 As shown, the present invention provides a foldable multi-faceted LED lighting lamp: including a housing 10, a main LED panel 11 fixedly installed inside the housing 10, two sets of sliding rods 13 slidably connected inside the housing 10, and a secondary LED panel 12 rotatably connected between each set of sliding rods 13. The two secondary LED panels 12 are symmetrically arranged and slidably connected between the main LED panel 11 and the back plate of the housing 10 through the sliding rods 13. Therefore, the secondary LED panels 12 can be slidably folded behind the main LED panel 11. When in use, the two secondary LED panels 12 can slide out from behind the main LED panel 11 and unfold on both sides of the main LED panel 11 to cooperate with the main LED panel 11 to expand the lighting range.

[0039] After the slide bar 13 drives the secondary LED panel 12 to unfold, since the secondary LED panel 12 and the slide bar 13 are rotatably connected at the end near the main LED panel 11, the two secondary LED panels 12 can deflect towards the main LED panel 11 to adjust the lighting angle, thereby improving the concentrated lighting effect of the light. One side of each of the two secondary LED panels 12 is connected to a wire 14 for powering them.

[0040] Reference Figures 2-4 as well as Figures 6-8Inside the housing 10, between the two secondary LED panels 12, a wire control mechanism 20 is provided. The wire control mechanism 20 includes a mounting shell 21 fixed inside the housing 10. After the two secondary LED panels 12 are folded, they fit against the two sides of the mounting shell 21 respectively. The upper and lower ends of the mounting shell 21 are rotatably connected to the first gear 22. The ends of the two sets of slide rods 13 near the mounting shell 21 are each provided with a first toothed rod 23. The two first toothed rods 23 are symmetrically arranged about the center of the mounting shell 21 and are respectively meshed with the two first gears 22. A core rod 24 is fixed on one side of the first gear 22. A winding spool 25 is slidably sleeved on the outside of the core rod 24.

[0041] When the secondary LED panel 12 is pushed to retract into the back of the main LED panel 11 to achieve folding, the secondary LED panel 12 and the slide bar 13 drive the first toothed bar 23 to move, and the first toothed bar 23 drives the first gear 22 meshing with it to rotate in the opposite direction, thereby causing the core rod 24 and the winding drum 25 to rotate in the opposite direction. The winding drum 25 rotates to wind the redundant wire 14.

[0042] When the secondary LED panel 12 is manually pulled outward, the transmission principle is the same as described above. At this time, the winding drum 25 rotates in the forward direction to release the wire 14, so that the wire 14 remains connected to the secondary LED panel 12.

[0043] Therefore, during the unfolding and folding of the secondary LED panel 12, the wire 14 remains straight. This design not only prevents the wire 14 from being damaged by friction with surrounding objects and prevents the wire 14 from becoming loose and broken due to increased tension at the connection point with the secondary LED panel 12, but also prevents the wire 14 from getting tangled and being squeezed and bent when the secondary LED panel 12 is folded, thus extending the service life of the wire 14. The advantages of this design are even more prominent when the LED panel needs to be unfolded over a large area to allow for a longer redundancy in the wire 14.

[0044] Reference Figure 7 and Figure 8 In traditional multi-layer winding, the upper conductor 14 will exert continuous pressure on the lower conductor 14, and the insulation layer is easily damaged due to misalignment and friction between the conductors 14. To solve this problem, a wire guide assembly 26 is provided at one end of the winding drum 25. The wire guide assembly 26 includes a threaded post 261 fixed to one end of the winding drum 25. A screw cylinder 262 that is threadedly connected to the threaded post 261 is fixed inside the mounting shell 21. When the winding drum 25 rotates, it drives the threaded post 261 to rotate, so that the threaded post 261 drives the winding drum 25 to move axially through the thread under the action of the screw cylinder 262.

[0045] When the winding drum 25 rotates to wind the wire 14, the axial movement of the winding drum 25 at the same time allows the wire 14 to be wound onto the winding drum 25 in an orderly manner, turn by turn. Conversely, when the winding drum 25 rotates to release the wire 14, the wire 14 on the winding drum 25 can be released in an orderly manner, and the number of layers of wire 14 on the winding drum 25 does not exceed a single layer. This design can prevent the wire 14 from being locally stacked and wound on the winding drum 25, which would cause squeezing and friction between the wires 14, thus protecting the wire 14.

[0046] The mounting housing 21 has a positioning sleeve 263 fixed inside. After the wire 14 passes through the positioning sleeve 263, it is wound and connected to the winding drum 25. The positioning sleeve 263 is used to limit the release and winding position of the wire 14, further improving the neatness of the winding of the wire 14.

[0047] The release or winding speed of the lead wire 14 is always synchronized with the displacement speed of the secondary LED panel 12. Under the action of the wiring assembly 26, the orderly winding and release of the lead wire 14 can maintain a constant winding and release speed. This design can improve the fit between the release length of the lead wire 14 and the displacement of the secondary LED panel 12, so that the lead wire 14 between the secondary LED panel 12 and the winding drum 25 always remains straight, reducing the possibility of the lead wire 14 contacting and rubbing against the surrounding structure, and avoiding the lead wire 14 becoming slack or too tight during the movement of the secondary LED panel 12, thus eliminating additional stress damage.

[0048] Reference Figures 7-9 The housing 21 houses a controller 40 that is electrically connected to an external power source and the main LED panel 11. A connection unit 27 and a power connection unit 28 are provided between the controller 40 and the wire 14.

[0049] The connection unit 27 includes a limiting cylinder 271 fixed inside the mounting housing 21, and a slider 272 rotatably connected to the end of the threaded column 261 is slidably connected inside the limiting cylinder 271; the power connection unit 28 includes a male connector 281 fixed inside the slider 272, and a female connector 282 electrically connected to the controller 40 and the male connector 281 is fixed inside the mounting housing 21.

[0050] The wire 14 is wound around the winding drum 25 and passes through the winding drum 25 and through the inside of the threaded post 261. The wire 14 and the male end 281 are electrically connected by a conductive slip ring 29. The conductive slip ring 29 consists of a rotating end and a fixed end. The fixed end is fixed inside the threaded post 261 and electrically connected to the end of the wire 14. The rotating end is electrically connected to the male end 281. The axis of the conductive slip ring 29 coincides with the axis of the threaded post 261.

[0051] like Figure 8 and Figure 9For example, when the secondary LED panel 12 is folded, the winding drum 25 rotates to wind the wire 14. The winding drum 25 drives the threaded post 261 to rotate, causing the threaded post 261 to move downward axially in the screw cylinder 262. The screw cylinder 262 drives the slider 272 to move downward, causing the male end 281 to separate from the female end 282. During this process, the wire 14 and the male end 281 rotate relative to each other. Under the connection of the conductive slip ring 29, the wire 14 and the male end 281 always maintain an electrical connection.

[0052] When the male connector 281 and the female connector 282 are connected, an external power source can supply power to the secondary LED panel 12 through the controller 40, the power receiving unit 28, the conductive slip ring 29 and the wire 14. The secondary LED panel 12 can only be electrically connected to the controller 40 after it is unfolded. This design not only prevents the secondary LED panel 12 from being accidentally opened and wasting power when it is folded and stored, but also reduces the risk of electric shock when manually controlling the unfolding and folding of the secondary LED panel 12, thus improving safety.

[0053] It is worth mentioning that when the secondary LED panel 12 is folded, it is in an open circuit state with the controller 40. At this time, the external power supply supplies power to the main LED panel 11 through the controller 40, and the main LED panel 11 can be used normally. In this case, if the circuit of the main LED panel 11 fails, the circuit of the secondary LED panel 12 is in a power-free safe state, so that the fault cannot be transmitted to the circuit of the secondary LED panel 12, avoiding cascading failures and greatly reducing the overall maintenance cost.

[0054] Reference Figure 5 and Figure 10 Considering that the wire 14 also needs to be released when the sub-LED panel 12 is deflected, an additional structure 30 is provided inside the slide bar 13. The additional structure 30 includes a second gear 31 fixed on the rotating shaft of the sub-LED panel 12, and a second gear 32 fixed at one end of the first gear 23 near the slide bar 13. The second gear 32 is slidably connected inside the slide bar 13 and meshes with the second gear 31.

[0055] When the secondary LED panel 12 unfolds and deflects towards the direction of the main LED panel 11, it drives the second gear 31 to rotate. The rotation of the second gear 31 drives the second toothed rod 32 to slide into the slide rod 13, thereby pulling the first toothed rod 23. The first toothed rod 23 drives the first gear 22 to rotate, which in turn drives the core rod 24 and the winding drum 25 to rotate and release the wire 14. The length of the wire 14 meets the rotation requirements of the secondary LED panel 12, and the length of the released wire 14 increases with the increase of the deflection angle of the secondary LED panel 12. This avoids the wire 14 being stretched or redundantly bent, significantly reducing the risk of insulation layer damage and internal copper core fatigue, and extending the service life.

[0056] The frictional forces on the second gear 31 and the first rack 23, and the frictional forces between the threaded column 261 and the screw barrel 262 restrict the rotation of the second gear 31 and the secondary LED panel 12. Therefore, the secondary LED panel 12 needs to overcome a certain resistance when it is adjusted. Under the action of this resistance, the secondary LED panel 12 can stay stably after the angle is adjusted without the need for an additional locking structure.

[0057] Working principle: Initial state is Figure 8 As shown in the figure, the following motion process is based on Figure 8 Taking the state shown as an example, the secondary LED panel 12 is in a fully unfolded state, the male connector 281 and the female connector 282 are electrically connected and there is a gap between them, allowing the male connector 281 to continue to move upward. The external power supply powers the main LED panel 11 through the controller 40, and powers the secondary LED panel 12 through the controller 40, the power receiving unit 28, the conductive slip ring 29 and the wire 14. The main LED panel 11 and the secondary LED panel 12 perform the lighting effect.

[0058] When the secondary LED panel 12 is manually deflected toward the main LED panel 11 to concentrate the light, the secondary LED panel 12 drives the second gear 31 to rotate. The rotation of the second gear 31 drives the second rack 32 to slide into the slide bar 13, thereby pulling the first rack 23. The first rack 23 drives the first gear 22 to rotate, which drives the core rod 24 and the winding drum 25 to rotate in the forward direction to release the wire 14. The length of the wire 14 meets the rotation requirements of the secondary LED panel 12. At this time, the rotation of the winding drum 25 drives the threaded column 261 to move upward. The threaded column 261 pushes the slider 272 and the male head 281 to move upward. When the male head 281 moves, it maintains an electrical connection with the female head 282.

[0059] Similarly, when the secondary LED panel 12 is deflected and reset, the second gear 31 drives the second rack 32 to rotate in the opposite direction, causing the first rack 23 to move in the opposite direction, which in turn drives the core rod 24 and the winding drum 25 to rotate and wind the wire 14.

[0060] When the secondary LED panel 12 is folded and stored, the secondary LED panel 12 drives the second toothed bar 32 and the first toothed bar 23 to move. The first toothed bar 23 drives the first gear 22 to rotate. The first gear 22 drives the core rod 24 and the winding drum 25 to rotate in the opposite direction, so that the winding drum 25 winds up the wire 14. At the same time, the threaded column 261 moves downward in the screw cylinder 262 through the thread, driving the winding drum 25 to slide axially outside the core rod 24, so that the wound wire 14 is arranged in an orderly and neat manner on the winding drum 25.

[0061] The threaded post 261 moves downward, causing the slider 272 to move downward. The slider 272 then causes the male head 281 to move downward, separating the male head 281 from the female head 282, thus disconnecting the circuit of the secondary LED panel 12 and improving the safety of the secondary LED panel 12 when it is folded.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the present invention's foldable multi-faceted LED lighting lamp and its inventive concept, should be covered within the scope of protection of the present invention.
