Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and more specifically, to a quick-connect device for LED driver power supply and emergency power supply. Background Technology

[0002] In the current lighting field, LED lights, with their advantages of low energy consumption, long lifespan, and high luminous efficacy, have been widely used in various scenarios such as residential homes, commercial complexes, industrial plants, and public transportation hubs. Currently, the vast majority of LED lights rely on mains power (220V AC) for power supply, and their operation is entirely dependent on the stability of the power grid. Once a mains power outage occurs (such as line faults caused by natural disasters, power grid maintenance, or sudden power outages), the LED lights will immediately stop working and cannot continue to provide illumination.

[0003] As users' demands for the reliability and adaptability of lighting systems continue to upgrade, many scenarios urgently require LED lights to have the ability to "continue to work after the mains power is cut off": for example, temporary lighting in home scenarios to cope with sudden power outages at night, emergency evacuation lighting in commercial venues to meet fire safety regulations, and temporary mobile lighting in outdoor construction or camping scenarios. These demands make it difficult for traditional LED lights that rely solely on mains power to cover them, thus limiting their application boundaries.

[0004] While some LED lights with emergency lighting functions exist on the market, their core solution involves powering the LED lights with an independent emergency power supply (battery pack). However, these products generally use a wire connection design: the emergency power supply needs to be soldered to the LED light's driver power supply via conductive wires or connected through terminals. This connection method has significant drawbacks: firstly, installation requires additional wiring planning, making the process complex; secondly, later maintenance or replacement of the emergency power supply requires disconnecting the conductive wires, rewiring, and debugging after maintenance, which is not only time-consuming and labor-intensive but may also lead to safety hazards such as poor contact and short circuits due to improper wiring, while also increasing professional installation costs. In summary, the existing connection structure design of emergency LED lights has become a key pain point restricting their widespread application. Utility Model Content

[0005] This application mainly addresses the technical problems of existing LED driver power supplies and emergency power supplies using wire welding or terminal plugging, which leads to inconvenience in disassembly and assembly, safety hazards caused by improper wiring, and slow emergency response. To overcome the above-mentioned defects of the prior art, this application provides a quick connection device for LED driver power supplies and emergency power supplies.

[0006] This application provides a quick-connect device for LED driver power supply and emergency power supply, including: The LED driver power module is electrically connected to the mains power supply and is used to power the LED lamp. An emergency power supply assembly includes an emergency drive module and a battery pack mounted on the emergency drive module, the battery pack being electrically connected to the emergency drive module; A conductive part, used to establish an electrical connection between the LED driver power module and the emergency drive module, includes a first conductive element disposed on the LED driver power module and a second conductive element disposed on the emergency drive module. The first conductive element is electrically connected to the LED lamp, and the second conductive element is electrically connected to the battery pack. The connecting part includes a first magnetic component and a second magnetic component that can magnetically attract each other. The first magnetic component is fixed to the LED driver power module, and the second magnetic component is fixed to the emergency drive module, for detachable connection between the LED driver power module and the emergency drive module. When the first magnetic component and the second magnetic component attract each other, the LED driver power module and the emergency drive module are driven to move closer to each other and be fixedly connected, and the first conductive component and the second conductive component are made to contact each other and conduct electricity.

[0007] Compared with existing technologies, this application presents a quick-connect device for LED driver power supply and emergency power supply, which has the following advantages: Through the collaborative design of the "magnetic connection part and conductive part," it completely eliminates the traditional wire welding or terminal plugging methods, enabling quick connection and disconnection of the LED driver power supply module and the emergency drive module. This significantly simplifies the installation process and reduces reliance on professional construction and operating costs. During the magnetic attraction process, the first and second magnetic components drive the two modules to move closer and fix them together, while the first and second conductive components contact each other to form an electrical connection. No additional debugging is required, fundamentally reducing safety hazards such as poor contact and short circuits caused by improper wiring, and improving circuit reliability. The emergency power supply component adopts an "emergency drive module and detachable battery pack" structure. When replacing the battery pack, there is no need to disconnect the LED driver and emergency drive module; only the battery pack needs to be removed separately, shortening maintenance downtime. This is particularly suitable for scenarios with high requirements for lighting continuity, such as commercial venues and public transportation hubs.

[0008] In one possible implementation, the device further includes a positioning unit disposed between the LED driver power module and the emergency drive module, used to guide the LED driver power module and the emergency drive module to align during the magnetic attraction process. Compared with the prior art, the positioning unit can guide the two modules to accurately align during the magnetic attraction process, avoiding the inability of the first and second conductive components to effectively contact each other due to magnetic deviation, thus solving the problems of "inaccurate alignment and poor contact" that may exist in magnetic connections. It also reduces repeated adjustments during magnetic attraction, improving assembly efficiency, and is particularly suitable for batch installations or installation scenarios with limited space.

[0009] In one possible implementation, the positioning part includes at least two sets of spaced-apart positioning components. Each set of positioning components includes a positioning post and a positioning blind hole adapted to the positioning post. The positioning post is fixed to the emergency drive module, and the positioning blind hole is formed in the LED driver power module; or, the positioning post is fixed to the LED driver power module, and the positioning blind hole is formed in the emergency drive module. Compared with the prior art, the positioning component adopts a simple structure of "positioning post and positioning blind hole," which is easy to process, low in cost, and can provide a stable guiding effect, avoiding assembly redundancy caused by complex positioning structures.

[0010] In one possible implementation, the first magnetic component is fixed to the bottom of the positioning blind hole, and the second magnetic component is fixed to the end of the positioning post. Compared with the prior art, integrating the magnetic component into the positioning structure allows the three steps of "positioning, magnetic attraction, and fixing" to be completed simultaneously, eliminating the need for an additional independent magnetic component mounting position, simplifying the overall structure, and saving internal space of the module. Simultaneously, the coaxial arrangement of the magnetic component and the positioning structure further enhances alignment accuracy, ensuring precise contact of the conductive components during magnetic attraction and improving the reliability of the electrical connection.

[0011] In one possible implementation, the device further includes an auxiliary locking structure, which comprises an elastic latch and an auxiliary slot that engages with the elastic latch. One of the elastic latch and the auxiliary slot is disposed on the LED driver power module, and the other is disposed on the emergency drive module. When the positioning post is inserted into the positioning blind hole, the elastic latch engages into the auxiliary slot, and the engagement direction of the elastic latch is perpendicular to the insertion direction of the positioning post. Compared with the prior art, the auxiliary locking structure provides additional mechanical locking force after the positioning post is inserted into the positioning blind hole through the "elastic latch perpendicular to the insertion direction," preventing the two modules from falling off due to vibration or accidental collision, thus improving connection stability. The elastic latch design has the characteristics of "easy to engage and easy to disengage," requiring only slight external force to release the lock during disassembly, without affecting the overall "quick-release" advantage, balancing stability and disassembly.

[0012] In one possible implementation, both the first and second magnetic components are permanent magnets, or one is a permanent magnet and the other is a magnetically conductive material. Compared to existing technologies, this supports combinations of two magnetic components: "dual permanent magnets" and "permanent magnets and magnetically conductive materials," allowing for flexible selection based on actual needs. The use of a magnetically conductive material avoids the "reverse magnetic interference" problem that may exist with dual permanent magnets, improves the stability of the magnetic attraction direction, and ensures that the module will not shift due to magnetic repulsion during connection.

[0013] In one possible implementation, the first conductive element is a conductive contact piece, and the second conductive element is a spring pin; or, the first conductive element is a spring pin, and the second conductive element is a conductive contact piece. Compared with the prior art, the combination of "conductive contact piece and spring pin" has elastic compensation capability, that is, the spring pin can ensure close contact with the conductive contact piece through its own elastic deformation when there are slight errors in assembly, thus solving the problem of poor contact caused by dimensional deviations of rigid conductive elements.

[0014] In one possible implementation, the LED driver power module includes a control circuit connected to mains power and equipped with a control switch. When the LED driver power module and the emergency drive module are connected via the connection part, the control switch is triggered to open, causing the control circuit to control the emergency power supply component to enter emergency power supply mode. Compared with the prior art, this achieves "automatic triggering" of the emergency power supply mode: when the two modules are connected, the control switch opens synchronously, eliminating the need for manual switching. After a mains power outage, the emergency power supply component can quickly enter the power supply mode, improving emergency response speed and ensuring lighting continuity.

[0015] In one possible implementation, the device further includes a mounting base on which both the LED driver power module and the emergency power component are detachably connected. Compared to existing technologies, the mounting base integrates the LED driver power module and the emergency power component, further improving the reliability of the connection between them. Furthermore, during later maintenance, either module can be disassembled individually without requiring the entire installation structure to be disassembled, thus enhancing maintenance convenience.

[0020] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] See Figures 1 to 6 This application discloses a quick-connect device for LED driver power supply and emergency power supply, including: LED driver power supply module 1, emergency power supply component 2, conductive part 3, connecting part 4, positioning part 5, auxiliary locking structure 6, and mounting base 8.

[0022] The input terminals of LED driver power module 1 are electrically connected to the mains power (AC 220V), and the output terminals are electrically connected to the LED lamp. Internally, it includes a rectifier circuit, a step-down converter, and a control circuit to convert the mains power into a low DC voltage suitable for LED operation. The module housing is made of insulating plastic, and the internal circuit board is fixed inside the housing.

[0023] The emergency power supply assembly 2 includes an emergency drive module 21 and a battery pack 22. The emergency drive module 21 is an independent circuit unit integrating battery management circuitry (such as charging control, discharge protection, and status monitoring). The battery pack 22 is detachably mounted on the emergency drive module 21 via a slot-type interface. The battery pack 22 is a rechargeable lithium battery pack, with its capacity designed according to lighting requirements. The battery pack 22 can be charged via a dedicated charger or the charging circuit integrated into the emergency drive module 21.

[0024] The conductive part 3 includes a first conductive element 31 and a second conductive element 32. The first conductive element 31 is fixed to the surface of the housing of the LED driver power module 1 and consists of at least two copper conductive contacts (corresponding to positive and negative terminals), which are electrically connected to the output circuit of the LED driver power module 1. The second conductive element 32 is fixed to the surface of the housing of the emergency drive module 21 and consists of a spring-loaded pogo pin that matches the conductive contacts, which is electrically connected to the output circuit of the battery pack 22. When the two modules are connected, the spring-loaded pogo pin is pressed and makes tight contact with the conductive contacts, thus achieving electrical conduction.

[0025] The connecting part 4 includes a first magnetic element 41 and a second magnetic element 42. The second magnetic element 42 is a circular permanent magnet (such as a neodymium iron boron magnet), which is embedded in and fixed to the outer shell of the emergency drive module 21. The first magnetic element 41 is a matching permanent magnet, embedded in the corresponding position of the outer shell of the LED driver power module 1. When the two modules approach each other, the magnetic attraction drives them to automatically move closer and fix together, while simultaneously making the conductive part 3 contact and conduct electricity. In another embodiment, the first magnetic element 41 is a magnetic conductor (such as a low-carbon steel sheet), which reduces costs.

[0026] During normal operation, the LED driver power module 1 supplies power to the LED lights via mains power. When an emergency function is required, the emergency power component 2 is magnetically connected to the LED driver power module 1: the magnetic force quickly aligns and secures the two modules, and the first conductive element 31 and the second conductive element 32 make contact and conduct electricity. After a mains power outage, the emergency power component 2 switches to battery power, providing emergency power to the LED lights through the conductive part 3.

[0027] In this embodiment, the positioning part 5 is located between the mating surfaces of the LED driver power module 1 and the emergency drive module 21, and includes two sets of positioning components spaced apart. Each set of positioning components includes a cylindrical positioning post 51 and a matching positioning blind hole 52. The positioning post 51 is fixed to the outer shell of the emergency drive module 21, and the positioning blind hole 52 is formed on the outer shell of the LED driver power module 1. During the magnetic attraction process, when the user brings the emergency drive module 21 close to the LED driver power module 1, the positioning post 51 first inserts into the positioning blind hole 52, physically guiding the two modules to precisely align and preventing misalignment. This ensures that the first conductive element 31 and the second conductive element 32 make accurate contact under magnetic attraction, avoiding poor contact caused by misalignment. The two spaced positioning components work together to improve connection stability and prevent relative rotation of the modules. In another embodiment, the positioning post 51 is fixed to the outer shell of the LED driver power module 1, and the positioning blind hole 52 is formed on the outer shell of the emergency drive module 21.

[0028] In this embodiment, the first magnetic element 41 is embedded and fixed to the bottom of the positioning blind hole 52. The second magnetic element 42 is embedded and fixed to the end of the positioning post 51, with the opposite polarity to the first magnetic element 41. When the positioning post 51 is inserted into the positioning blind hole 52, the magnetic elements attract each other, enhancing the connection force and assisting the conductive part 3 in rapid electrical conduction. Magnetic attraction plays a dominant role in the positioning process, ensuring alignment accuracy between the positioning post 51 and the blind hole. This integrated design reduces additional space occupation and is suitable for compact lighting fixture structures.

[0029] In this embodiment, the auxiliary locking structure 6 includes an elastic locking protrusion 61 and an auxiliary locking groove 62 that engages with the elastic locking protrusion 61. The elastic locking protrusion 61 is a cantilever beam structure, integrally formed on the housing of the LED driver power module 1; the auxiliary locking groove 62 is a recess, formed on the corresponding side wall of the housing of the emergency drive module 21. When the positioning post 51 is fully inserted into the positioning blind hole 52, the elastic locking protrusion 61 engages with the auxiliary locking groove 62 under elastic force. The engaging direction of the elastic locking protrusion 61 is perpendicular to the insertion direction of the positioning post 51 to prevent the module from disengaging due to accidental vibration. During disassembly, the user needs to slide the emergency drive module 21 in the opposite direction of the insertion of the positioning post 51 to release the locking protrusion and achieve quick separation.

[0030] In this embodiment, a control switch 7 is provided on the control circuit inside the LED driver power module 1. When the emergency drive module 21 is connected to the LED driver power module 1 through the connecting part 4, the toggle structure 211 of the housing of the emergency drive module 21 mechanically toggles the control switch 7, and the trigger signal causes the control circuit to switch the emergency power component 2 to the emergency power supply state.

[0031] In this embodiment, the mounting base 8 is a bracket structure. The LED driver power module 1 and the emergency power component 2 are provided with elastic buckles on their backs, which match the buckle slots on the mounting base 8 to achieve a detachable connection.

[0032] The beneficial effects of this application include: First, it abandons the traditional wire welding or terminal plug connection, and realizes quick connection and quick disconnection between LED driver power module 1 and emergency drive module 21 through the cooperation of magnetic connection part 4 and conductive part 3, which simplifies the installation process, reduces construction costs, and reduces the risk of poor contact and short circuit caused by improper wiring.

[0033] 2. The emergency power supply component 2 adopts a detachable battery pack 22 design, which eliminates the need to disconnect the two drive connections when replacing the battery, shortening maintenance downtime and making it suitable for scenarios with high requirements for lighting continuity; the conductive parts use a combination of spring pins and conductive contacts, and elastic compensation ensures good contact.

[0034] 3. Positioning unit 5 guides precise alignment and avoids magnetic deviation; auxiliary locking structure 6 uses elastic locking protrusion 61 to prevent vibration and detachment, and does not affect quick release; control switch 7 realizes automatic triggering in emergency state and improves response speed; mounting base 8 integrates two modules, improves connection reliability, and allows for separate disassembly of the modules for maintenance.
