Description

Technical Field

[0001] This invention relates to the field of LED lighting technology, and in particular to a solderless energy-saving LED lighting fixture and its structure. Background Technology

[0002] High-power LED beads with lenses possess directional focusing characteristics and are commonly used in light boxes, billboards, and other scenarios requiring localized focused lighting. They can also serve as light source components for ceiling lights and panel lights. The light source and the light fixture are typically fixed together by soldering. Metal wires such as gold, aluminum, or copper are used to connect the exposed electrodes on the LED beads to pads on a rigid circuit board, forming a current loop. Obviously, this soldering connection method makes the installation process complex and reduces production efficiency. Furthermore, when the LED light source fails, the soldered connection method makes LED bead replacement difficult, raising the maintenance threshold and increasing usage and maintenance costs.

[0003] In conclusion, there is an urgent need for a solderless energy-saving LED lighting fixture and structure that is easy to install and replace, and reduces operating costs. Summary of the Invention

[0007] As a preferred technical solution, the negative pressure generator includes a negative pressure chamber and a rotating disk. The negative pressure chamber is a cavity structure located within the mounting bracket. The outer wall of the rotating disk is the inner wall of the negative pressure chamber, and the outer wall of the rotating disk is tangent to the outer wall of the negative pressure chamber. The negative pressure chamber is provided with an air inlet and an air outlet, wherein the air inlet and the air outlet are located on opposite sides of a tangent position. The rotating disk is provided with a telescopic isolation groove, and the electrical connector can telescopically move within the telescopic isolation groove, thereby separating the negative pressure chamber.

[0009] As a preferred technical solution, the negative pressure chamber is equipped with an elastic partition plate, which can open and close the air outlet.

[0011] As a preferred technical solution, the rotating disk is provided with a polishing disc, the polishing disc is attached to the conductive strip, the polishing disc rotates with the rotating disk, and the rotation trajectory of the polishing disc covers the position on the conductive strip that contacts the electrical connector, wherein the upper surface of the conductive strip is not lower than the upper surface of the mounting plate.

[0012] As a preferred technical solution, the rotating disk is provided with a drive shaft tube at its center, and the mounting bracket is provided with a drive column. While the drive shaft tube moves along the drive column, the rotating disk rotates around the drive column. The grinding disk is also provided with an opening structure, wherein when the elastic isolation plate is opened, the opening structure is located above the position where the conductive strip contacts the electrical connector.

[0013] As a preferred technical solution, the grinding disc is elastically connected to the rotating disc.

[0014] In view of the problems of complex installation processes and difficult replacement in existing technologies, a solderless energy-saving LED lamp is proposed. To solve the above problems, the technical solution of this invention is as follows:

[0015] A solderless energy-saving LED lamp, characterized in that it comprises: the solderless energy-saving LED lamp structure; an LED light source is provided inside the lamp body, wherein when the negative pressure suction cup is adsorbed onto the mounting bracket, the LED light source is attached to and maintains electrical connection with the electrical connector.

[0016] The beneficial effects of this invention are:

[0017] 1. The solderless energy-saving LED structure of the present invention achieves detachable installation of the lamp and the mounting bracket by providing a negative pressure suction cup that can generate negative pressure suction on the lamp body. The mounting bracket is provided with a conductive strip, and the lamp body is provided with an electrical connector adapted to the conductive strip. While the lamp is being installed by suction, the circuit is also made conductive. This allows the mounting bracket to be flexibly assembled with LED lamps according to actual needs, eliminating the soldering process, greatly improving assembly efficiency, facilitating replacement, and reducing usage costs.

[0018] 2. The negative pressure generator on the lamp body includes a negative pressure chamber and a rotating disk. An electrical connector for electrical connection is located on the rotating disk, dividing the negative pressure chamber. During rotation, the change in volume of the negative pressure chamber reduces the air pressure inside the negative pressure suction cup, achieving stable adsorption.

The grinding disc has an opening structure. Simultaneously, an elastic isolation plate is provided inside the negative pressure chamber, so that during the rotation of the electrical connector, a low pressure is formed on one side of the negative pressure chamber, while the other side... The ballast chamber generates high pressure. When the elastic isolation plate is opened, the opening structure is located above the conductive strip after it has been polished by the polishing disc. The gas in the high-pressure negative pressure chamber is sprayed out from the outlet onto the polished conductive strip, thus cleaning the dust on the conductive strip. Immediately afterwards, the electrical connector rotates back above the conductive strip. Under the action of the drive shaft tube at the center of the rotating disc and the drive column on the mounting bracket, the electrical connector is engaged between the conductive strip and the conductive body, completing the installation and electrical connection between the lamp body and the mounting bracket. At the same time as installation, rust removal and cleaning of the conductive strip at the electrical connection position are achieved, further improving installation efficiency and ensuring the stability of the electrical connection.

[0019] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0032] Please see the appendix Figure 1 , Figure 1 This is a three-dimensional schematic diagram of the solderless energy-saving LED lamp and its structure according to the present invention. A solderless energy-saving LED lamp structure includes a lamp body 1 and a mounting bracket 2. The lamp body 1 is a housing structure for mounting the lamp source, and the mounting bracket 2 is a bracket for mounting the lamp body 1. Wires on the mounting bracket 2 connect to external circuitry. The lamp body 1 and the mounting bracket 2 are detachably installed to achieve circuit connectivity and fix the position of the lamp body 1. Compared to soldering, this method is more flexible in disassembly, allowing for easy replacement of damaged LED beads within the lamp body 1 through simple disassembly and reassembly without soldering, thus lowering the maintenance threshold. Specifically, please refer to the appendix for details. Figure 2 Appendix Figure 3 , Figure 2 This is a three-dimensional schematic diagram of the mounting bracket described in this invention. Figure 3 for Figure 2 A partially enlarged schematic diagram of section A; the mounting bracket 2 includes a mounting plate 21 and a conductive strip 22. The mounting plate 21 is a cuboid substrate structure, and the conductive strip 22 is a conductive strip structure embedded in the mounting plate 21, such as a copper sheet; please refer to the appendix. Figure 4 , Figure 4This is a three-dimensional schematic diagram of the lamp body according to the present invention. The bottom of the lamp body 1 is provided with a negative pressure generator 11, a negative pressure suction cup 12, and an electrical connector 3. The negative pressure generator 11 provides negative pressure to the negative pressure suction cup 12, allowing it to adhere to the mounting bracket 2. When the negative pressure suction cup 12 is adhered to the mounting bracket 2, one end of the electrical connector 3 on the lamp body 1 is in contact with the conductive strip 22 on the mounting plate 21, and the other end of the electrical connector 3 is connected to the light source inside the lamp body 1, thereby achieving circuit continuity. Furthermore, the upper surface of the conductive strip 22 is on the same plane as the upper surface of the mounting plate 21, facilitating the adhesion of the negative pressure suction cup 12.

[0033] In this invention, when in use, the negative pressure suction cup 12 is placed on the mounting plate 21 of the mounting bracket 2, and then the negative pressure generator 11 generates negative pressure in the negative pressure suction cup 12 to fix the lamp body 1 on the mounting bracket 2. The negative pressure adsorption method can overcome the complexity of welding connection, and it has better disassembly and convenience compared with the adhesive connection method.

[0034] Please see the appendix Figure 5 Appendix Figure 6 Appendix Figure 7 ; Figure 5 for Figure 4 A three-dimensional schematic diagram of the two sets of negative pressure generators. Figure 6 This is a three-dimensional schematic diagram of the negative pressure generator separated from the lamp body. Figure 7This is a top view of the negative pressure generator. Specifically, in some embodiments, the negative pressure generator 11 includes a negative pressure chamber 13 and a rotating disk 14. The negative pressure chamber 13 is a cavity structure inside the bottom of the lamp body 1. The outer wall 131 of the inner cavity of the negative pressure chamber 13 is a circular structure. The rotating disk 14 is a disc structure. The diameter of the rotating disk 14 is smaller than the diameter of the outer wall 131 of the inner cavity of the negative pressure chamber 13. The outer wall of the rotating disk 14 is tangent to the outer wall 131 of the inner cavity of the negative pressure chamber 13. A sealing gasket is symmetrically provided on both sides of the tangent line. The width of the two sealing gaskets is greater than the width of the telescopic isolation groove 141, so that no matter where the telescopic isolation groove 141 is located, the negative pressure chamber 13 is a sealed cavity with only an air intake 132 and an air outlet 133. The negative pressure chamber 13 is bounded by the outer wall 131 of the inner cavity and the outer wall of the rotating disk 14, and its thickness is smaller than the thickness of the rotating disk 14, so that it can form a sealed cavity structure with the outer wall of the rotating disk 14. With the inner tangent line intersecting the rotating disk 14 and the negative pressure chamber 13 as the boundary, the air intake 132 and the air outlet 133 are respectively located on both sides of the inner tangent line. One end of the air intake 132 and the air outlet 133 are connected to the cavity of the negative pressure chamber 13, wherein the other end of the air intake 132 is connected to the groove of the negative pressure suction cup 12 through a pipe, and the other end of the air outlet 133 is connected to the external environment through a pipe. In order to form an effective negative pressure in the negative pressure chamber 13, a telescopic isolation groove 141 is provided on the rotating disk 14. The telescopic isolation groove 141 is a groove-shaped structure provided on the rotating disk 14 along its radial direction, and the groove opening of the telescopic isolation groove 141 penetrates the outer surface of the rotating disk 14. The electrical connector 3 is a cylindrical structure adapted to the telescopic isolation groove 141. One end of the electrical connector 3 is elastically connected to the telescopic isolation groove 141 near the central axis of the rotating disk 14 via a spring piston column, and the other end is an arc-shaped structure. Under the action of the spring piston, it always keeps in contact with the inner cavity outer wall 131 of the negative pressure chamber 13. That is, the electrical connector 3 forms a separation effect on the negative pressure chamber 13. Specifically, two adjacent cavities are formed with the contact position of the spring piston with the inner cavity outer wall 131 of the negative pressure chamber 13 and the position of the inner tangent as the boundary. As the position of the electrical connector 3 changes, the volume of the two cavities on both sides increases or decreases accordingly.In use, simply press the lamp body 1 onto the mounting bracket 2, forming a closed cavity between the negative pressure suction cup 12 at the bottom and the mounting bracket 2. Then rotate the rotating disk 14, causing the electrical connector 3 to rotate within the negative pressure chamber 13. After the electrical connector 3 passes the air intake 132, the volume of the space where the air intake 132 is located gradually increases, thereby continuously drawing in air from the connected negative pressure suction cup 12, reducing the air pressure of the negative pressure suction cup 12. Meanwhile, in the space where the air outlet 133 is located on the other side, the volume of the space gradually decreases, and the air inside is discharged from the air outlet 133. In this embodiment, the electrical connector 3 does not pass the air outlet 13. 3. When the electrical connector 3 is rotated to the corresponding position, the electrical connector 3 is located on the conductive strip 22, and the negative pressure suction provided by the negative pressure chamber 13 is sufficient to overcome the weight of the lamp body 1 itself. It should be understood that two sets of negative pressure generators 11 and electrical connectors 3 are provided at the bottom of the lamp body 1, which are connected to the two conductive strips 22 on the mounting plate 21 to form an electrical connection circuit. Among them, a negative pressure suction cup 12 is provided at each of the four corners of the mounting bracket 2. Two of the negative pressure suction cups 12 are connected to the suction port 132 of one of the negative pressure suction cups 12 through a pipe, and the other two negative pressure suction cups 12 are connected to the suction port 132 of the other negative pressure suction cup 12.

[0035] During prolonged use, the conductive strip 22 on the mounting plate 21 is inevitably exposed to air and may corrode. This can affect the stability of the electrical connection, necessitating prior polishing of the conductive strip 22. To further simplify the installation process and improve efficiency, in this embodiment of the solderless energy-saving LED lamp structure, a polishing disc 16 is connected to the rotating disk 14. Preferably, the polishing disc 16 and the rotating disk 14 are also elastically connected via a spring piston rod. The polishing disc 16 rotates with the rotating disk 14, and its rotation trajectory covers the surface of the conductive strip 22 on the mounting plate 21 used to connect the electrical connector 3. The polishing disc 16 is a disc structure with an opening structure 161. More preferably, the air outlet 133 is oriented towards the surface of the conductive strip 22 used for electrical connection via a pipe. For further details, please refer to the appendix. Figure 8 , Figure 8 for Figure 7A partially enlarged schematic diagram of section B shows an elastic isolation plate 134 located on the side of the air outlet 133 away from the inner tangent. Under the action of a torsion spring, the two ends of the elastic isolation plate 134 are respectively attached to the outer wall 131 of the inner cavity of the negative pressure chamber 13 and the outer wall of the rotating disk 14, isolating the air outlet 133 from the negative pressure chamber 13. Under a certain pressure, the elastic isolation plate 134 will separate from the outer wall of the rotating disk 14, allowing the air outlet 133 to communicate with the negative pressure chamber 13.

[0036] To simplify the operation, a drive shaft tube 142 is provided in the central axis of the rotating disk 14. Preferably, the drive shaft tube 142 is connected to the rotating disk 14 via a one-way bearing. The tube wall of the drive shaft tube 142 is provided with a threaded guide groove 143. Correspondingly, the mounting plate 21 is provided with a drive column 23 that is adapted to the tube hole of the drive shaft tube 142. The drive column 23 is a column structure located on one side of the conductive strip 22. The drive column 23 is provided with a guide protrusion 231 that is adapted to the threaded guide groove 143. The guide protrusion 231 can move along the threaded guide groove 143.

[0037] The method of using the solderless energy-saving LED lamp structure of the present invention is as follows: In the initial state, the bottom of the lamp body 1 is directly opposite the mounting bracket 2. The negative pressure suction cup 12 on the mounting bracket 2 is in full contact with the mounting plate 21 to form a sealed cavity. At this time, the drive shaft tube 142 at the center of the rotating disk 14 is sleeved on the drive column 23, and the guide protrusion 231 enters the threaded guide groove 143. Preferably, the grinding disk 16 is in contact with the upper surface of the conductive strip 22, and the grinding disk 16 and the rotating disk 14 are in close contact. When the spring is compressed and the lamp body 1 is pressed down, the downward pressure on the grinding disc 16 gradually increases. Under the engagement and restriction of the guide protrusion 231 and the threaded guide groove 143, the drive shaft tube 142 starts to rotate during the pressing process, and drives the rotating disc 14 to rotate together through the one-way bearing. In this embodiment, counterclockwise rotation is taken as an example. During the rotation, the electrical connector 3 starts to move along the inner wall 131 of the negative pressure chamber 13. In the negative pressure chamber 13 on the left side of the electrical connector 3, due to the connection with the air outlet 133... The passage between them is isolated by the elastic isolation plate 134, causing the gas to be gradually compressed. Correspondingly, the volume of the negative pressure chamber 13 on the right side of the electrical connector 3 gradually expands, and the air pressure therein, including the air pressure in the negative pressure suction cup 12 connected through the air intake 132, gradually decreases, thereby realizing the adsorption installation between the lamp body 1 and the mounting bracket 2. The rotating disk 14 continues to rotate. When the electrical connector 3 rotates to the position of the elastic isolation plate 134, the electrical connector 3 applies a pressure to the elastic isolation plate 134, which, in conjunction with the high pressure of the compressed gas, creates a pressure that is beneficial to the lamp body 1. This causes the elastic isolation plate 134 to begin rotating and disengage from the outer wall of the rotating disk 14, releasing high-pressure gas from its outlet 133. It should be noted that during this process, as the grinding disc 16 rotates with the rotating disk 14, it remains in contact with the conductive strip 22 under the action of elasticity, and simultaneously produces a frictional grinding effect on the conductive strip 22 during rotation. The rotation trajectory of the grinding disc 16 covers the area where the electrical connection contacts the conductive strip 22. The grinding disc 16 has an opening structure 161; please refer to the appendix. Figure 9 , Figure 9This is a schematic diagram of the elastic isolation plate in its open state. When the elastic isolation plate is opened, the opening structure 161 is located above the polished conductive strip 22. The gas ejected from the vent 133 is directed towards the top of the polished conductive strip 22, thus cleaning the surface of the conductive strip 22. After rotation, the electrical connector 3 should rotate back to be above the conductive strip 22. In this embodiment, the electrical connector 3 is initially located directly above the conductive strip 22. After rotating an integer number of times, it is also located directly above the conductive strip 22. Under the guidance of the threaded guide groove 143, the position of the rotating disk 14 and the position of the electrical connector 3 gradually decrease. When the corresponding number of rotations is reached, the electrical connector 3 contacts the conductive strip 22 and continues to press down, further squeezing the electrical connector 3 between the lamp body 1 and the conductive strip 22, greatly ensuring the connection stability of the circuit. Preferably, the mounting bracket 2 is also provided with an air intake valve that communicates with the air intake 132 and the negative pressure suction cup 12. The air intake valve is normally closed in the initial state. When disassembling, the air intake valve is opened to allow external gas to enter the negative pressure chamber 13 to balance the internal and external pressures and release the negative pressure adsorption state. The lamp body 1 can then be removed from the mounting bracket 2. At the same time, when disassembling, the drive shaft tube 142 rotates in the opposite direction. Under the action of the one-way bearing, the rotating disk 14 does not rotate with the drive shaft tube 142.

[0038] The solderless energy-saving LED structure of this invention achieves detachable installation of the lamp and mounting bracket 2 by providing a negative pressure suction cup 12 that generates negative pressure suction on the lamp body 1. A conductive strip 22 is provided on the mounting bracket 2, and an electrical connector 3 adapted to the conductive strip 22 is provided on the lamp body 1. Simultaneously with suction installation, circuit conductivity is achieved, allowing the mounting bracket 2 to flexibly assemble LED lamps according to actual needs, eliminating the welding process, greatly improving assembly efficiency, facilitating replacement, and reducing operating costs. The negative pressure generator 11 on the lamp body 1 includes a negative pressure chamber 13 and a rotating disk 14. The electrical connector 3, used for electrical connection, is located on the rotating disk 14 and is used to divide the negative pressure chamber 13. During rotation, the change in volume of the negative pressure chamber 13 reduces the air pressure inside the negative pressure suction cup 12, achieving stable suction. A grinding disk 16 is provided below the rotating disk 14 and rotates with it. During rotation, the grinding disk 16... The grinding disc 16 can simultaneously grind and remove rust from the conductive strip 22 on the mounting bracket 2, preventing poor contact between the electrical connector 3 and the conductive strip 22. The grinding disc 16 has an opening structure 161, and the negative pressure chamber 13 has an elastic isolation plate 134. During the rotation of the electrical connector 3, one side of the negative pressure chamber 13 forms a low pressure, while the other side generates a high pressure. When the elastic isolation plate 134 is opened, the opening structure 161 is positioned above the conductive strip 22 after grinding by the grinding disc 16. Gas from the high-pressure negative pressure chamber 13 is ejected from the outlet 133 onto the ground conductive strip 22, cleaning the dust and debris from the conductive strip 22. Then, the electrical connector 3 rotates back above the conductive strip 22 and begins to engage between the conductive strip 22 and the conductive body. This simultaneous installation and rust removal at the electrical connection points on the conductive strip 22 further improves installation efficiency and ensures the stability of the electrical connection. It should be noted that the elastic force between the grinding disc 16 and the rotating disc 14 should be less than the negative pressure suction force provided by the negative pressure suction cup 12 under the lamp body 1, so as to avoid the reduction of the adsorption reliability of the negative pressure suction cup 12 under its elastic force; the elastic isolation plate 134 has the function of a one-way valve, which can prevent air from entering the negative pressure chamber 13 from the air outlet 133, so that the negative pressure chamber 13 and the negative pressure suction cup 12 can maintain the negative pressure adsorption capacity for a long time.

[0039] A solderless energy-saving LED lamp includes an LED light source disposed within the aforementioned energy-saving LED lamp structure. The LED light source is disposed within the lamp body 1. Two sets of electrical connectors 3 are provided below the lamp body 1. When one end of each electrical connector 3 is adsorbed onto the mounting bracket 2 by the negative pressure suction cup 12, it respectively contacts the positive and negative electrodes of the LED light source and achieves electrical connection.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and additions without departing from the principle of the present invention, and these improvements and additions should also be considered within the scope of protection of the present invention.
