Description

Technical Field

[0001] This invention relates to the field of LED lighting fixtures, and more specifically, to combined bifacial LED lighting fixtures. Background Technology

[0002] An LED light is an electroluminescent semiconductor chip, which is cured onto a support using silver or white glue. The chip and circuit board are then connected by silver or gold wires, and the entire assembly is sealed with epoxy resin to protect the internal wiring. Finally, a casing is installed. Therefore, LED lights have good shock resistance. An LED (Light Emitting Diode) is a solid-state semiconductor device that converts electrical energy into visible light; it directly converts electricity into light. The heart of an LED is a semiconductor chip, with one end attached to a support, serving as the negative electrode, and the other end connected to the positive electrode of the power supply.

[0003] Chinese patent CN103742815B discloses an LED tube that connects the bracket and the lamp head through a connecting component to offset the extension or contraction of the bracket under different temperature conditions, thereby ensuring that the length of the LED tube remains unchanged. A gap is set between the end of the lamp cover and the base of the lamp head to prevent the lamp cover or lamp head from breaking when it stretches due to heat. This makes the LED tube suitable for different temperature environments and expands its application range.

[0004] While the aforementioned patent achieves the effect of preventing the lampshade or lamp head from cracking due to heat expansion and contact with the lamp head, the aforementioned LED tube can only illuminate to one side, with a small illumination range, making it difficult to apply to multi-directional lighting. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a combined double-sided LED light fixture. When a double-sided LED light fixture is needed, simply move the first driving copper plate into the interior of the first mounting housing to achieve the illumination of two LED strips. The LED strips in the first and second mounting housings illuminate in opposite directions, thereby achieving illumination at different angles and improving the lighting effect. The first mounting housing can be used independently, even without being combined with the second mounting housing, and can be selected as needed, thus broadening its applicability.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A combined double-sided LED light fixture includes a first mounting shell, a first secondary conductive post fixedly connected to one side of the first mounting shell, a mounting plate fixedly connected inside the first mounting shell, an LED light strip electrically connected to the first secondary conductive post fixedly connected to the bottom of the mounting plate, a first lampshade fixedly connected to the top of the first mounting shell, a first main conductive post electrically connected to the rear side of the LED light strip near the first secondary conductive post, the mounting plate being a transparent plastic plate, a second mounting shell detachably connected to the bottom of the first mounting shell, a second lampshade fixedly connected to the bottom of the second mounting shell, a second secondary conductive post fixedly connected to the front end of the second mounting shell near the first secondary conductive post, a second main conductive post fixedly connected to the rear end of the LED light strip inside the second mounting shell near the second secondary conductive post, and a connecting mechanism provided between the first mounting shell and the second mounting shell.

[0008] The connecting mechanism includes a first driving copper plate slidably connected inside the first mounting housing. A first spring is fixedly connected to the bottom of the inside of the first mounting housing. The first driving copper plate extends to form a first connecting copper plate on the side near the first spring.

[0009] Furthermore, a second driving copper plate is slidably connected to the top of the second mounting shell, a second spring is fixedly connected to the inner top of the second mounting shell, and the second driving copper plate extends to form a second connecting copper plate on the side near the second spring.

[0010] Furthermore, the top of the first spring is attached to the first conductive post, and the bottom of the second spring is attached to the second conductive post.

[0011] Furthermore, plastic sleeves are slidably connected to the surfaces of the second slave conductive post, the second main conductive post, the first slave conductive post, and the first main conductive post, and the cross-sectional shape of the first spring and the second spring is arc-shaped.

[0012] Furthermore, an extension block is fixedly connected to the side of the plastic sleeve away from the first driving copper plate, and a first spring is welded to one side of the extension block.

[0013] Furthermore, a movable plate is slidably connected to the bottom of the first mounting shell, and a fixed plate is fixedly connected to the top of the second mounting shell. The bottom of the movable plate extends to form multiple L-shaped blocks.

[0014] Furthermore, the fixed plate has a limiting groove inside corresponding to the position of the L-shaped block to accommodate the movement of the L-shaped block. A second spring is welded to the side of the moving plate away from the first driving copper plate. When the first driving copper plate does not move, the second spring is in a naturally extended state.

[0015] Furthermore, a second triangular block is rotatably connected to the bottom of the first mounting shell near the plastic sleeve, and a first triangular block is rotatably connected to the top of the second mounting shell near the plastic sleeve. Rotating rods are rotatably connected inside both the first and second triangular blocks.

[0016] Furthermore, magnets are fixedly connected to the contact surfaces of the first and second triangular blocks, and the contact surfaces of the two magnets are opposite magnetic poles.

[0017] Furthermore, a convex ring is fixedly connected to the surface of the rotating rod, and an annular groove is provided inside the first triangular block to accommodate the movement of the convex ring. A return spring welded to the convex ring is provided inside the annular groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. When a double-sided LED light fixture is required, this solution simply requires moving the first driving copper plate into the first mounting housing. This causes the LED strips inside the first mounting housing to emit light. The current flowing through the LED strips in the first mounting housing reaches the first main conductive post and then flows back into the lamp housing, thus completing the illumination. Furthermore, when the first and second mounting housings are in contact, both LED strips emit light. The LED strips in the first and second mounting housings emit light in opposite directions, thereby achieving illumination at different angles and improving the lighting effect. The first mounting housing can also be used independently, without being combined with the second mounting housing, and can be selected according to needs, making it more widely applicable.

[0020] 2. This solution protects the first and second conductive posts with a plastic sleeve, effectively preventing operators from accidentally touching the second and first conductive posts, thus providing better personnel protection. When the device is used alone, if the second conductive post and the second main conductive post are inserted into the lamp housing, the lamp housing wall blocks the plastic sleeve. As the second conductive post and the second main conductive post are inserted, the plastic sleeve moves into the interior of the second mounting housing. The plastic sleeve moves to the position of the second spring and squeezes the second spring, thus deforming the second spring.

[0021] 3. This design utilizes the arc-shaped cross-section of the second spring to ensure a tighter fit between the first and second springs and the second and first conductive posts. When the plastic sleeve compresses the second spring, it deforms and separates from the second conductive post, preventing current from the second conductive post from reaching the outside. This enhances the safety of the device and lamp housing installation. Furthermore, the plastic sleeve on the surface of the first conductive post inside the first mounting housing also provides the same effect, further improving the device's protection. Since the first and second springs are arc-shaped, they return to their original positions after the plastic sleeve is removed, allowing the device to be reused.

[0022] 4. This solution uses a movable L-shaped block to engage with the limiting groove, thus fixing the first and second mounting shells together. This makes fixing the first and second mounting shells easier and eliminates the need for manual fixing by personnel, making it more convenient to use. When the first drive copper plate is stationary, the second spring is in a naturally extended state. This allows the moving plate to compress the second spring after movement. The compression causes the second spring to change from a naturally extended state to a taut state, allowing the moving plate to return to its original position under the action of the second spring. The L-shaped block below the moving plate also returns to its original position, thereby releasing the fixation between the first and second mounting shells. This makes the assembly and disassembly of the first and second mounting shells much easier.

[0023] 5. This solution rotates the second triangular block and the first triangular block so that the cross-sectional shape of the combined second triangular block and the first triangular block is rectangular. This facilitates blocking the first driving copper plate and the second driving copper plate and prevents them from moving. The contact surfaces of the two magnets are opposite magnetic poles, which facilitates fixing the first triangular block and the second triangular block together and makes the fixing effect of the first triangular block and the second triangular block on the first driving copper plate and the second driving copper plate better.

[0024] 6. In this design, the first triangular block moves on the surface of the rotating rod. At this time, the first triangular block is engaged in the outer shells of the first and second mounting housings. Similarly, the second triangular block is also engaged in the outer shells of the first and second mounting housings, thus preventing the first and second triangular blocks from disengaging. The first triangular block and the convex ring compress the return spring, allowing the first triangular block to return to its original position without being compressed by the lamp housing, facilitating device disassembly. When the first and second mounting housings need to be disassembled, simply press the first triangular block, which drives the first driving copper plate to move along with the moving plate, while the first triangular block and the second driving copper plate remain unchanged. At this time, the moving plate disengages from the fixed plate, and the first and second triangular blocks disengage from each other, making the disassembly of the first and second mounting housings more convenient.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 9A combined double-sided LED light fixture includes a first mounting shell 1. A first conductive post 12 is fixedly connected to one side of the first mounting shell 1, through which current is conducted to the interior of a first lampshade 11. A mounting plate 14, made of transparent plastic, is fixedly connected inside the first mounting shell 1, allowing light from the LED strip 4 to pass through while also protecting the LED strip 4. An LED strip 4, electrically connected to the first conductive post 12, is fixedly connected to the bottom of the mounting plate 14, illuminating the LED strip 4. A first lampshade 11 is fixedly connected to the top of the first mounting shell 1, through which light passes. 1. Illumination to the outside: The LED light strip 4 is electrically connected to the first main conductive post 13 at the rear end near the first secondary conductive post 12. Current flows through the first main conductive post 13. The bottom of the first mounting shell 1 is detachably connected to the second mounting shell 2. The bottom of the second mounting shell 2 is fixedly connected to the second lampshade 21. The front end of the second mounting shell 2 near the first secondary conductive post 12 is fixedly connected to the second secondary conductive post 22. Inside the second mounting shell 2, the same LED light strip 4 and mounting plate 14 as the first mounting shell 1 are fixedly connected. The identical first mounting shell 1 and second mounting shell 2 facilitate production and have a wider range of applications. Inside the second mounting shell 2, the rear end of the LED light strip 4 near the second secondary conductive post 22 is fixedly connected to the second main conductive post 23. A connecting mechanism 3 is provided between a first mounting shell 1 and a second mounting shell 2. The connecting mechanism 3 includes a first driving copper plate 31 slidably connected to the inside of the first mounting shell 1. When a double-sided LED light fixture is needed, the first driving copper plate 31 is simply moved to move into the inside of the first mounting shell 1. A first spring piece 38 is fixedly connected to the bottom inside the first mounting shell 1. The side of the first driving copper plate 31 near the first spring piece 38 extends to form a first connecting copper plate 311. By moving the first driving copper plate 31, the first connecting copper plate 311 can be moved to the position of the first spring piece 38, realizing the connection between the first driving copper plate 31 and the first spring piece 38. A second driving copper plate 37 is slidably connected to the top of the second mounting shell 2. By moving the second driving copper plate... 37. The second spring 39 is fixedly connected to the inner top of the second mounting shell 2. The second driving copper plate 37 extends from the side near the second spring 39 to form a second connecting copper plate 371. During the movement of the second driving copper plate 37, the second connecting copper plate 371 moves to the position of the second spring 39, realizing communication between the second driving copper plate 37 and the second spring 39. When the first mounting shell 1 and the second mounting shell 2 are combined, the first driving copper plate 31 contacts the second driving copper plate 37, thereby realizing communication between the first spring 38 and the second spring 39. The top of the first spring 38 is in contact with the first secondary conductive post 12, and the bottom of the second spring 39 is in contact with the second secondary conductive post 22. At this time, it is only necessary to insert the second main conductive post 23 and the first main conductive post 13 into the lamp housing.The current first enters from the second main conductive post 23, passes through the LED strip 4 inside the second mounting housing 2, and illuminates the LED strip 4. Then, the current passes through the LED strip 4 to the second secondary conductive post 22, and sequentially passes through the second spring contact 39, the second connecting copper plate 371, and the second driving copper plate 37 to the first driving copper plate 31. The current then flows along the first connecting copper plate 311 and the first spring contact 38 to the first secondary conductive post 12. The first secondary conductive post 12 is electrically connected to the LED strip 4 inside the first mounting housing 1, facilitating the first... The LED strip 4 inside the mounting housing 1 emits light, and the current flowing through the LED strip 4 in the first mounting housing 1 reaches the first main conductive post 13 and then re-enters the lamp housing along the first main conductive post 13, thus completing the illumination. Furthermore, when the first mounting housing 1 and the second mounting housing 2 are attached, the LED strip 4 inside the first mounting housing 1 and the second mounting housing 2 illuminate in opposite directions, thereby achieving illumination from different angles and improving the lighting effect. The first mounting housing 1 can also be used independently, without being combined with the second mounting housing 2, allowing for selection based on needs and a wider range of applications.

[0038] like Figures 1 to 9As shown, plastic sleeves 24 are slidably connected to the surfaces of the second slave conductive post 22, the second main conductive post 23, the first slave conductive post 12, and the first main conductive post 13. The plastic sleeves 24 enclose the second slave conductive post 22, thus protecting the second slave conductive post 22, the second main conductive post 23, the first slave conductive post 12, and the first main conductive post 13. Furthermore, when the device is assembled, the first main conductive post 13 and the second main conductive post 23 are inserted into the lamp housing. At this time, the second slave conductive post 22 and the first slave conductive post 12 are not inserted, but this does not result in the second slave conductive post 22 and the first slave conductive post 12 being exposed to the outside. The plastic sleeve 24 protects the first and second conductive posts 12 and 22, effectively preventing operators from accidentally touching them. This provides better personnel protection. Furthermore, when the device is used alone, if the second conductive post 22 and the second main conductive post 23 are inserted into the lamp housing, the lamp housing wall blocks the plastic sleeve 24. As the second conductive post 22 and the second main conductive post 23 are inserted, the plastic sleeve 24 moves into the interior of the second mounting shell 2. The plastic sleeve 24 moves to the position of the second spring piece 39 and compresses it, deforming the second spring piece 39. The cross-sectional shape of the first spring 38 and the second spring 39 is arc-shaped, which facilitates a tighter fit between the first spring 38 and the second spring 39 and the second conductive post 22 and the first conductive post 12. When the plastic sleeve 24 squeezes the second spring 39, the second spring 39 deforms and separates from the second conductive post 22, preventing the current from the second conductive post 22 from reaching the outside through the second spring 39. This makes the installation of the device and the lamp housing safer. The plastic sleeve 24 on the surface of the first conductive post 12 inside the first mounting housing 1 also has the above-mentioned effect, making the device more protective. The spring 39 has an arc surface. When the plastic sleeve 24 is removed, the first spring 38 and the second spring 39 return to their original positions. The device can be reused. An extension block 241 is fixedly connected to the side of the plastic sleeve 24 away from the first driving copper plate 31. When the plastic sleeve 24 moves, it can move the extension block 241 with it. A first spring 242 is welded to one side of the extension block 241. By moving the extension block 241, the extension block 241 compresses the first spring 242, and the first spring 242 changes from its original naturally extended state to a taut state, so that the plastic sleeve 24 can return to its original position under the action of the first spring 242.

[0039] like Figures 1 to 9As shown, a movable plate 33 is slidably connected to the bottom of the first mounting shell 1. During the movement of the first driving copper plate 31, the movement of the first driving copper plate 31 presses against the movable plate 33, allowing the movable plate 33 to move inside the first mounting shell 1. A fixed plate 34 is fixedly connected to the top of the second mounting shell 2. The bottom of the movable plate 33 extends to form multiple L-shaped blocks 331. By moving the fixed plate 34, the L-shaped blocks 331 move inside the fixed plate 34. The fixed plate 34 has a limiting groove 341 corresponding to the position of the L-shaped blocks 331 to accommodate their movement. This allows the moving L-shaped blocks 331 to be inserted into the limiting groove 341, thus fixing the first mounting shell 1 and the second mounting shell 2 together. The fixing between the shells 2 is more convenient, eliminating the need for staff to fix the first mounting shell 1 and the second mounting shell 2 separately, making it more convenient to use. A second spring 35 is welded to the side of the moving plate 33 away from the first driving copper plate 31. When the first driving copper plate 31 is not moving, the second spring 35 is in a naturally extended state, which facilitates the movement of the moving plate 33 and the compression of the second spring 35. The second spring 35 is compressed and changes from a naturally extended state to a taut state, which facilitates the moving plate 33 returning to its original position under the action of the second spring 35. The L-shaped block 331 under the moving plate 33 returns to its original position, thereby releasing the fixing between the first mounting shell 1 and the second mounting shell 2, making the assembly and disassembly of the first mounting shell 1 and the second mounting shell 2 more convenient.

[0040] like Figures 1 to 9 As shown, a second triangular block 36 is rotatably connected to the bottom of the first mounting shell 1 near the plastic sleeve 24, and a first triangular block 32 is rotatably connected to the top of the second mounting shell 2 near the plastic sleeve 24. Rotating rods 321 are rotatably connected inside both the first triangular block 32 and the second triangular block 36. By rotating the second triangular block 36 and the first triangular block 32, the combined cross-sectional shape of the second triangular block 36 and the first triangular block 32 becomes rectangular, facilitating the blocking of the first driving copper plate 31 and the second driving copper plate 37 and preventing movement between them. Magnets 325 are fixedly connected to the contact surfaces of the first triangular block 32 and the second triangular block 36. The contact surfaces of the two magnets 325 have opposite magnetic poles, facilitating the fixing of the first triangular block 32 and the second triangular block 36 and improving the fixing effect of the first triangular block 32 and the second triangular block 36 on the first driving copper plate 31 and the second driving copper plate 37.

[0041] like Figures 1 to 9As shown, a convex ring 322 is fixedly connected to the surface of the rotating rod 321. When the device is installed into the lamp housing, the first triangular block 32 moves under the pressure of the lamp housing. The interior of the first triangular block 32 has an annular groove 323 to accommodate the movement of the convex ring 322, facilitating the movement of the first triangular block 32 on the surface of the rotating rod 321. At this time, the first triangular block 32 is engaged in the outer shells of the first mounting shell 1 and the second mounting shell 2. Similarly, the second triangular block 36 is also engaged in the outer shells of the first mounting shell 1 and the second mounting shell 2, preventing the first triangular block 32 and the second triangular block 36 from disengaging. A return spring 324, welded to the convex ring 322, is provided inside the annular groove 323. During the movement of the first triangular block 32, the first triangular block 32 and the convex ring 322 press against the return spring 324, so that the first triangular block 32 does not return to its original position without being squeezed by the lamp housing, which facilitates the disassembly of the device. When it is necessary to disassemble the first mounting shell 1 and the second mounting shell 2, simply press the first triangular block 32 to drive the first driving copper plate 31 to move the moving plate 33, while the first triangular block 32 and the second driving copper plate 37 remain unchanged. At this time, the moving plate 33 is disengaged from the fixed plate 34, and the first triangular block 32 is disengaged from the second triangular block 36, making the disassembly of the first mounting shell 1 and the second mounting shell 2 more convenient.

[0042] The above are merely preferred embodiments of the present invention; however, 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 technical solution and its improved concept, should be covered within the scope of protection of the present invention.
