Description

Technical Field

[0001] The present invention relates to the field of LED lamps, and more particularly to a combined double-sided light-emitting LED lamp. Background Art

[0002] An LED lamp is a chip of electro-luminescent semiconductor material, which is cured to a bracket with silver glue or white glue, then the chip and the circuit board are connected with silver wires or gold wires, and the periphery is sealed with epoxy resin to protect the internal core wires. Finally, the outer shell is installed. Therefore, the LED lamp has good seismic performance. The LED light-emitting diode is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. The heart of the LED is a semiconductor wafer. One end of the wafer is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply.

[0003] The Chinese patent with the authorization announcement number CN103742815B discloses an LED lamp tube. The bracket and the lamp head are connected through a connecting component to offset the extension or contraction length of the bracket in different temperature environments, so as to ensure that the length of the LED lamp tube remains unchanged. A gap is provided between the end of the lamp cover and the base of the lamp head to prevent the lamp cover or the lamp head from cracking when the lamp cover extends due to heat and abuts against the lamp head. Therefore, the LED lamp tube is applicable to different temperature environments and has an expanded scope of use.

[0004] Although the above patent achieves the effect of preventing the lamp cover or the lamp head from cracking when the lamp cover extends due to heat and abuts against the lamp head, the above LED lamp tube can only irradiate in one direction, with a small irradiation range and is difficult to be applied to multi-directional lighting. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a combined double-sided light-emitting LED lamp. When a double-sided light-emitting LED lamp is needed, only move the first driving copper plate to make the first driving copper plate move into the interior of the first mounting shell, and then the two LED light strips can emit light. The illumination directions of the LED light strips in the first mounting shell and the second mounting shell are opposite, so as to achieve illumination at different angles and make the illumination effect better. Moreover, when the first mounting shell is not combined with the second mounting shell, it can also be an independent device and can be selected according to requirements, with a wider scope of application.

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

[0007] Combined double-sided lighting LED lamp, including a first mounting shell, one side of the first mounting shell is fixedly connected with a first secondary conductive post, the inside of the first mounting shell is fixedly connected with a mounting plate, the bottom of the mounting plate is fixedly connected with an LED strip electrically connected to the first secondary conductive post, the top of the first mounting shell is fixedly connected with a first lamp cover, one end rear side of the LED strip close to the first secondary conductive post is electrically connected with a first main conductive post, the mounting plate is a transparent plastic plate, the bottom of the first mounting shell is detachably connected with a second mounting shell, the bottom of the second mounting shell is fixedly connected with a second lamp cover, one side front end of the second mounting shell close to the first secondary conductive post is fixedly connected with a second secondary conductive post, one side rear end of the LED strip in the second mounting shell close to the second secondary conductive post is fixedly connected with a second main conductive post, and a connection mechanism is arranged between the first mounting shell and the second mounting shell;

[0008] The connection mechanism includes a first driving copper plate slidably connected inside the first mounting shell, the inner bottom of the first mounting shell is fixedly connected with a first elastic piece, and one side of the first driving copper plate close to the first elastic piece extends to form a first connecting copper plate.

[0009] Further, a second driving copper plate is slidably connected to the top of the second mounting shell, the inner top of the second mounting shell is fixedly connected with a second elastic piece, and one side of the second driving copper plate close to the second elastic piece extends to form a second connecting copper plate.

[0010] Further, the top of the first elastic piece is in contact with the first secondary conductive post, and the bottom of the second elastic piece is in contact with the second secondary conductive post.

[0011] Further, plastic sleeves are slidably connected to the surfaces of the second secondary conductive post, the second main conductive post, the first secondary conductive post and the first main conductive post, and the cross-sectional shapes of the first elastic piece and the second elastic piece are arc-shaped.

[0012] Further, an extension block is fixedly connected to one 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] Further, a moving plate is slidably connected to the bottom of the first mounting shell, a fixing plate is fixedly connected to the top of the second mounting shell, and a plurality of L-shaped blocks are formed by extending the bottom of the moving plate.

[0014] Further, a limiting groove for accommodating the movement of the L-shaped block is opened at the position corresponding to the L-shaped block inside the fixing plate, and a second spring is welded to one 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 natural stretching state.

[0015] Further, 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. A rotating rod is rotatably connected inside both the first triangular block and the second triangular block.

[0016] Further, magnets are fixedly connected to the positions of the contact surfaces between the first triangular block and the second triangular block, and the contact surfaces of the two magnets are opposite magnetic poles.

[0017] Further, a convex ring is fixedly connected to the surface of the rotating rod. An annular groove for the convex ring to move is formed inside the first triangular block, and a return spring welded to the convex ring is arranged 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 lighting LED lamp is needed in this solution, only the first driving copper plate needs to be moved to make the first driving copper plate move into the first mounting shell, so that the LED light strip in the first mounting shell emits light. After the current passing through the LED light strip in the first mounting shell reaches the first main conductive column, it enters the lamp housing again along the first main conductive column, thus completing lighting. And when the first mounting shell is attached to the second mounting shell, the two LED light strips emit light, and the lighting directions of the LED light strips in the first mounting shell and the second mounting shell are opposite, so as to achieve lighting at different angles and make the lighting effect better. Moreover, when the first mounting shell is not combined with the second mounting shell, it can also be a separate device and can be selected according to needs, with a wider range of applications.

[0020] 2. In this solution, the plastic sleeve protects the first secondary conductive column and the second secondary conductive column, and effectively prevents the operator from accidentally touching the second secondary conductive column and the first secondary conductive column, providing better protection for personnel. And when the device is used alone, such as when the second secondary conductive column and the second main conductive column are inserted into the lamp housing, at this time, the lamp housing wall blocks the plastic sleeve. As the second secondary conductive column and the second main conductive column are inserted, the plastic sleeve moves into the second mounting shell, and the plastic sleeve moves to the position of the second elastic sheet and squeezes the second elastic sheet, causing the second elastic sheet to deform.

[0021] 3. In this solution, the cross-sectional shape of the second elastic sheet is arc-shaped, which is convenient for the first elastic sheet and the second elastic sheet to always fit more closely with the second secondary conductive column and the first secondary conductive column. When the plastic sleeve squeezes the second elastic sheet, the second elastic sheet deforms and separates from the second secondary conductive column, preventing the current of the second secondary conductive column from reaching the outside along the second elastic sheet, making the installation of the device and the lamp housing safer. And the plastic sleeve on the surface of the first secondary conductive column in the first mounting shell also has the above effect, making the protection effect of the device better. And the first elastic sheet and the second elastic sheet are arc-shaped. After the plastic sleeve leaves, the first elastic sheet and the second elastic sheet return to their original positions, and the device can be reused.

[0022] 4. In this solution, the fixed connection between the first mounting shell and the second mounting shell is realized by inserting a moving L-shaped block into the internal limiting groove, which makes the fixing between the first mounting shell and the second mounting shell more convenient. There is no need for the staff to fix the first mounting shell and the second mounting shell separately, making it more convenient to use. When the first driving copper plate does not move, the second spring is in a natural extended state, which is convenient for the moving plate to squeeze the second spring after moving. The second spring is squeezed and changes from the natural extended state to a tightened state, which is convenient for the moving plate to return to its original position under the action of the second spring. The L-shaped block under the moving plate returns to its original position, thereby releasing the fixation between the first mounting shell and the second mounting shell, making the combination and disassembly between the first mounting shell and the second mounting shell more convenient.

[0023] 5. In this solution, by rotating the second triangular block and the first triangular block, the cross-sectional shape after the combination of the second triangular block and the first triangular block is rectangular, which is convenient for blocking the first driving copper plate and the second driving copper plate to prevent the movement between the first driving copper plate and the second driving copper plate. The contact surfaces of the two magnets are opposite-sex magnetic poles, which is convenient for fixing between the first triangular block and the second triangular block, making 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 solution, the first triangular block moves on the surface of the rotating rod. At this time, the first triangular block is inserted into the outer shells of the first mounting shell and the second mounting shell. Similarly, the second triangular block is also inserted into the outer shells of the first mounting shell and the second mounting shell, realizing the prevention of the separation between the first triangular block and the second triangular block. The first triangular block and the convex ring squeeze the return spring, which is convenient for the first triangular block to return to its original position without being squeezed by the lamp housing, facilitating the disassembly of the device. When it is necessary to disassemble the first mounting shell and the second mounting shell, just press the first triangular block to drive the first driving copper plate to drive the moving plate to move, while the first triangular block and the second driving copper plate remain unchanged. At this time, the moving plate is separated from the fixed plate, and the first triangular block and the second triangular block are separated, making the disassembly between the first mounting shell and the second mounting shell more convenient.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 to 9, The combined double-sided lighting LED lamp includes a first mounting shell 1. One side of the first mounting shell 1 is fixedly connected with a first secondary conductive column 12. The current is conducted through the first secondary conductive column 12 to the inside of the first lamp shade 11. Inside the first mounting shell 1, there is a fixedly connected mounting plate 14. The mounting plate 14 is a transparent plastic plate. While facilitating the light of the LED strip 4 to pass through, the mounting plate 14 protects the LED strip 4, and the protection effect on the LED strip 4 is better. The bottom of the mounting plate 14 is fixedly connected with an LED strip 4 electrically connected to the first secondary conductive column 12. The current is conducted through the first secondary conductive column 12 to the LED strip 4 to light up the LED strip 4. The top of the first mounting shell 1 is fixedly connected with a first lamp shade 11, and the light is irradiated to the outside through the first lamp shade 11. One side rear of the end of the LED strip 4 close to the first secondary conductive column 12 is electrically connected with a first main conductive column 13. The bottom of the first mounting shell 1 is detachably connected with a second mounting shell 2. The bottom of the second mounting shell 2 is fixedly connected with a second lamp shade 21. One side front of the second mounting shell 2 close to the first secondary conductive column 12 is fixedly connected with a second secondary conductive column 22. Inside the second mounting shell 2, there is a fixedly connected LED strip 4 and a mounting plate 14 identical to that of the first mounting shell 1. The identical first mounting shell 1 and second mounting shell 2 facilitate the production of workers and have a wider range of applications. One side rear of the end of the LED strip 4 in the second mounting shell 2 close to the second secondary conductive column 22 is fixedly connected with a second main conductive column 23. A connection mechanism 3 is arranged between the first mounting shell 1 and the second mounting shell 2. The connection mechanism 3 includes a first driving copper plate 31 slidably connected to the inside of the first mounting shell 1. When a double-sided lighting LED lamp is needed, only need to move the first driving copper plate 31 to make the first driving copper plate 31 move towards the inside of the first mounting shell 1. The bottom of the inside of the first mounting shell 1 is fixedly connected with a first elastic piece 38. One side of the first driving copper plate 31 close to the first elastic piece 38 extends to form a first connecting copper plate 311. By moving the first driving copper plate 31, it is convenient for the first connecting copper plate 311 to move to the position of the first elastic piece 38 to realize the connection between the first driving copper plate 31 and the first elastic piece 38. The top of the second mounting shell 2 is slidably connected with a second driving copper plate 37. By moving the second driving copper plate 37, the top of the inside of the second mounting shell 2 is fixedly connected with a second elastic piece 39. One side of the second driving copper plate 37 close to the second elastic piece 39 extends to form a second connecting copper plate 371. When the second driving copper plate 37 moves, the second connecting copper plate 371 moves to the position of the second elastic piece 39 to realize the connection between the second driving copper plate 37 and the second elastic piece 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, so as to realize the connection between the first elastic piece 38 and the second elastic piece 39. The top of the first elastic piece 38 is in contact with the first secondary conductive column 12, and the bottom of the second elastic piece 39 is in contact with the second secondary conductive column 22. At this time, only need to insert the second main conductive column 23 and the first main conductive column 13 into the lamp shell,The current first enters from the second main conductive column 23. The current passes through the LED light strip 4 in the second mounting shell 2, causing the LED light strip 4 in the second mounting shell 2 to light up. Then, after the current passes through the LED light strip 4 and reaches the second secondary conductive column 22, the current successively passes through the second elastic sheet 39, the second connecting copper plate 371, and the second driving copper plate 37 and then reaches the first driving copper plate 31. The current follows the first connecting copper plate 311 and the first elastic sheet 38 to reach the first secondary conductive column 12. The first secondary conductive column 12 is electrically connected to the LED light strip 4 in the first mounting shell 1, facilitating the LED light strip 4 in the first mounting shell 1 to emit light. After the current passing through the LED light strip 4 in the first mounting shell 1 reaches the first main conductive column 13, it enters the lamp housing again along the first main conductive column 13, thus completing the lighting. Moreover, when the first mounting shell 1 is attached to the second mounting shell 2, the lighting directions of the LED light strips 4 in the first mounting shell 1 and the second mounting shell 2 are opposite, thereby achieving lighting at different angles and making the lighting effect better. If the first mounting shell 1 is not combined with the second mounting shell 2, it can also be a separate device and can be selected according to requirements, with a wider range of applications.,

[0038] Such as Figures 1 to 9As shown in the figure, plastic sleeves 24 are slidably connected to the surfaces of the second secondary conductive posts 22, the second main conductive posts 23, the first secondary conductive posts 12, and the first main conductive posts 13. The second secondary conductive posts 22 are wrapped by the plastic sleeves 24 to protect the second secondary conductive posts 22, the second main conductive posts 23, the first secondary conductive posts 12, and the first main conductive posts 13. When the devices are combined, the first main conductive posts 13 and the second main conductive posts 23 are inserted into the lamp housing. At this time, the second secondary conductive posts 22 and the first secondary conductive posts 12 are not inserted, and the second secondary conductive posts 22 and the first secondary conductive posts 12 will not be exposed to the outside. The plastic sleeves 24 protect the first secondary conductive posts 12 and the second secondary conductive posts 22, and effectively prevent the operator from accidentally touching the second secondary conductive posts 22 and the first secondary conductive posts 12, providing better protection for personnel. When the device is used alone, such as when the second secondary conductive posts 22 and the second main conductive posts 23 are inserted into the lamp housing, the lamp housing wall blocks the plastic sleeves 24 at this time. As the second secondary conductive posts 22 and the second main conductive posts 23 are inserted, the plastic sleeves 24 move towards the inside of the second mounting case 2. The plastic sleeves 24 move to the position of the second elastic pieces 39 and squeeze the second elastic pieces 39, causing the second elastic pieces 39 to deform. The cross-sectional shapes of the first elastic pieces 38 and the second elastic pieces 39 are arc-shaped, which facilitates the first elastic pieces 38 and the second elastic pieces 39 to always fit more closely with the second secondary conductive posts 22 and the first secondary conductive posts 12. When the plastic sleeves 24 squeeze the second elastic pieces 39, the second elastic pieces 39 deform and separate from the second secondary conductive posts 22, preventing the current of the second secondary conductive posts 22 from reaching the outside along the second elastic pieces 39, making the installation of the device and the lamp housing safer. Moreover, the plastic sleeves 24 on the surfaces of the first secondary conductive posts 12 in the first mounting case 1 also have the above effects, making the protection effect of the device better. The first elastic pieces 38 and the second elastic pieces 39 are arc-shaped. When the plastic sleeves 24 leave, the first elastic pieces 38 and the second elastic pieces 39 return to their original positions, and the device can be reused. A 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, the extension block 241 can be driven to move. A first spring 242 is welded to one side of the extension block 241. Through the movement of the extension block 241, the extension block 241 squeezes the first spring 242, and the first spring 242 changes from its original natural stretched state to a tense state, facilitating the plastic sleeve 24 to return to its original position under the action of the first spring 242.

[0039] Such as Figures 1 to 9As shown in the figure, a moving 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 the moving plate 33, and the moving plate 33 can move inside the first mounting shell 1. A fixing plate 34 is fixedly connected to the top of the second mounting shell 2. Multiple L-shaped blocks 331 are formed by extending the bottom of the moving plate 33. Through the movement of the fixing plate 34, the L-shaped blocks 331 move inside the fixing plate 34. A limiting groove 341 for accommodating the movement of the L-shaped blocks 331 is formed at the position corresponding to the L-shaped blocks 331 inside the fixing plate 34, facilitating the L-shaped blocks 331 in movement to be caught inside the limiting groove 341, realizing the fixation between the first mounting shell 1 and the second mounting shell 2, making the fixation between the first mounting shell 1 and the second mounting shell 2 more convenient. It is not necessary for the staff to fix the first mounting shell 1 and the second mounting shell 2 separately, and it is 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 does not move, the second spring 35 is in a natural stretched state, facilitating the extrusion of the second spring 35 after the movement of the moving plate 33. The second spring 35 is extruded and changes from the natural stretched state to a tense state, facilitating the moving plate 33 to return to its original position under the action of the second spring 35, and the L-shaped blocks 331 below the moving plate 33 return to their original positions, thereby releasing the fixation between the first mounting shell 1 and the second mounting shell 2, making the combination and disassembly between the first mounting shell 1 and the second mounting shell 2 more convenient.

[0040] As Figures 1 to 9 shown in the figure, 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. A rotating rod 321 is 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 cross-sectional shape after the combination of the second triangular block 36 and the first triangular block 32 is rectangular, facilitating the blocking of the first driving copper plate 31 and the second driving copper plate 37 and preventing the movement between the first driving copper plate 31 and the second driving copper plate 37. Magnets 325 are fixedly connected to the positions of the contact surfaces between the first triangular block 32 and the second triangular block 36, and the contact surfaces of the two magnets 325 are opposite magnetic poles, facilitating the fixation between the first triangular block 32 and the second triangular block 36 and making the fixation 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 better.

[0041] As 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 extrusion of the lamp housing. An annular groove 323 for accommodating the movement of the convex ring 322 is formed inside the first triangular block 32, 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 snapped into the outer shells of the first mounting shell 1 and the second mounting shell 2. Similarly, the second triangular block 36 is also snapped into the outer shells of the first mounting shell 1 and the second mounting shell 2, preventing the separation between the first triangular block 32 and the second triangular block 36. A return spring 324 welded to the convex ring 322 is arranged inside the annular groove 323. During the movement of the first triangular block 32, the first triangular block 32 and the convex ring 322 squeeze the return spring 324, facilitating the first triangular block 32 to return to its original position when not under the extrusion of the lamp housing, which is convenient for device disassembly. When the first mounting shell 1 and the second mounting shell 2 need to be disassembled, just press the first triangular block 32 to drive the first driving copper plate 31 to move the moving plate 33. The first triangular block 32 and the second driving copper plate 37 remain unchanged. At this time, the moving plate 33 is separated from the fixing plate 34, and the first triangular block 32 is separated 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 is only the preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improved concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
