Description

Technical Field

[0001] This invention relates to the technical fields of lighting devices and energy-saving lighting equipment, and in particular to an integrated LED lamp based on plug-in terminals. Background Technology

[0002] Currently, LED lights are widely used in indoor and outdoor lighting due to their advantages such as high efficiency, energy saving, and long lifespan. In large-scale lighting projects or scenarios requiring continuous arrangement of multiple lights (such as shopping malls, production lines, tunnels, bridges, etc.), it is often necessary to connect multiple independent LED lights in parallel to achieve wide-area, uniform lighting coverage.

[0003] In the prior art, there is a patent with publication number CN222747221U entitled "A Plug-in Externally Driven LED Strip Light." Its structure includes a lamp body with LED strips, plugs connected to both ends of the lamp body, and a power driver box mounted on the top surface of the lamp body. The power driver box has pin connectors fixed to its side, and conductive terminals for electrical connection to the LED strips are located inside the plugs. The plug-in electrical connection between the pin connectors and the conductive terminals enables quick assembly and disassembly between the driver power module and the lamp source module. While this solution improves the ease of assembly within a single lamp to some extent, its power driver box only has one AC power input port (i.e., a single AC input interface) for connecting to an external AC power source. This structure dictates that each LED lamp must independently draw power from the main power supply line; that is, each lamp needs to be connected to a separate AC input line.

[0004] In practical applications, when multiple LED lights need to be installed and powered in parallel, existing technologies typically employ two methods. Method 1: An external junction box or splitter is used to branch the main power supply line into multiple branches, each connected to the AC input port of one light fixture. This method requires the additional purchase and installation of multiple wiring accessories, increasing material costs and installation time, resulting in messy wiring, large space requirements, and often unreliable protection levels and wiring reliability of the external junction box. Method 2: Multiple lights' AC input lines are connected in parallel to the same terminal block using manual screwing or crimping. This method is cumbersome, inefficient, and the wiring quality depends heavily on the worker's skill level, easily leading to safety hazards such as poor contact and phase-to-phase short circuits. The risk of wiring errors is even higher in applications requiring three-phase power (such as industrial lighting).

[0005] Furthermore, existing LED lighting fixtures generally separate the driver power supply box from the AC wiring section (e.g., the driver power supply is built-in, and the junction box is external), or even if integrated into the same housing, they only have a single AC input function, failing to consider the wiring requirements for cascading expansion of multiple lighting fixtures. Therefore, existing technologies suffer from significant problems in parallel installation scenarios involving multiple LED lighting fixtures, including complex wiring structures, low installation efficiency, messy wiring, poor reliability, and a lack of standardized cascading interfaces. Summary of the Invention

[0006] To address the shortcomings of the existing technologies, this invention provides an integrated LED lighting fixture based on plug-in terminals. The aim is to enable a single LED lighting fixture to both power itself independently and act as a cascade node to supply power to adjacent lighting fixtures through an integrated mounting cavity and a wiring module integrating AC input, power output, and multi-lighting expansion interfaces. This simplifies the wiring process for multi-light installations and improves the integration and reliability of the lighting system.

[0011] Furthermore, the three-phase main path, three-phase power supply branch and three-phase extension branch inside the single-sided conductive terminal block are arranged in layers or in parallel inside the terminal block, and each path is provided with an insulating isolation strip or insulating isolation layer to prevent phase-to-phase short circuit.

[0012] Furthermore, the three-phase main circuit is simultaneously connected to the three-phase power supply branch and the three-phase extension branch, forming a one-in-two-out split structure for the three-phase AC power, so that one path of the input three-phase AC power flows to the drive power module and the other path flows to other independent LED lamps.

[0013] Furthermore, the integrated LED luminaire based on plug-in terminals also includes a power selection control module. The power selection control module is installed on the insulating surface of the single-sided conductive terminal block and is electrically connected to the signal path inside the single-sided conductive terminal block. The power selection control module includes at least two parallel power selection branches. Each power selection branch is equipped with a selection switch and a power setting resistor with different resistance values. By combining the on and off states of the selection switch, different voltage setting signals are output to the drive power supply module.

[0014] Furthermore, one end of the signal path of the single-sided conductive terminal block is electrically connected to the power selection control module, and the other end extends to the edge of the terminal block to form a signal interface that is plugged into the signal control terminal of the drive power module.

[0015] Furthermore, the position of the power selection control module corresponds to the operation window on the integrated mounting cavity, and the power selection control module can be directly operated through the operation window to switch power levels; the signal path is isolated from the three-phase main path, three-phase power supply branch and three-phase extension branch in the single-sided conductive terminal block, and is provided with an electromagnetic shielding layer to avoid crosstalk between the power signal and the three-phase AC power.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely 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 should fall within the scope of protection of the present invention.

[0020] Example 1 Please see Figures 1 to 3 As shown, this embodiment provides an integrated LED luminaire (hereinafter referred to as "luminaire") based on plug-in terminal blocks. This luminaire is mainly suitable for large-scale lighting scenarios that require multiple lights to be arranged continuously and powered in parallel, such as shopping malls, production lines, tunnels, bridges, and industrial plants.

[0021] The lighting fixture mainly includes: a light source module 500, an integrated mounting cavity 100, a driver power supply module 200, and a wiring module 300. The light source module 500 is the light-emitting unit of the lighting fixture, and may specifically include a plate-shaped LED light panel, a heat sink, and a light-transmitting cover. Several LED beads are mounted on the LED light panel, and its input terminal is electrically connected to the output terminal of the driver power supply module 200 via wires. In this embodiment, the structure of the light source module 500 can adopt a conventional structure in the art, such as including an aluminum profile substrate, an LED light panel mounted on it, and a PC light-transmitting cover fixed by clips, etc., which will not be described in detail here.

[0022] The integrated mounting cavity 100 is formed by integrating the drive power supply box and the junction box into one piece, i.e., a single molded housing structure. This housing is mounted on the back of the lamp source module 500. In this embodiment, the back of the lamp source module 500 is provided with a housing mounting area 510, and the bottom of the integrated mounting cavity 100 is mounted on the housing mounting area 510 by screws or clips.

[0023] The integrated mounting cavity 100 has a through-chamber inside, which is clearly divided into two functional areas separated by a safe distance through internal physical space isolation: a power supply area and a wiring area. The power supply area is used to install the driver power module 200, and the wiring area is used to install the wiring module 300. This integrated partition design, compared with the existing structure where the driver box and junction box are separate, can improve the integration of the entire lamp, reduce the number of parts, and make the internal electrical connections more compact and reliable. In addition, the internal physical space isolation divides the cavity of the integrated mounting cavity 100 into two functional areas, allowing the power supply area and wiring area to communicate but not be separated by a safe distance, thus improving the heat dissipation performance and safety performance of the lamp.

[0024] The driver power module 200 is installed within the power supply area. It integrates an AC-DC conversion circuit to convert the incoming three-phase AC power into the DC power required by the LED light panel. The output terminal of the driver power module 200 is connected to the LED light panel of the light source module 500 via a wire passing through a wire hole at the bottom of the integrated mounting cavity 100 and a wire post on the back of the light source module 500. The three-phase input terminals of the driver power module 200 are electrically connected to the wiring module 300 to obtain AC power.

[0025] The wiring module 300, installed within the wiring area, is crucial for enabling cascaded power supply to multiple lamps. The wiring module 300 includes plug-in terminals 311 and a single-sided conductive terminal block 320. The single-sided conductive terminal block 320 can be a PCB (printed circuit board) with an insulating top surface and a conductive layer on its inner layer. This conductive layer is formed with multiple internal conductive paths through processes such as etching. In this embodiment, these conductive paths include a three-phase main path, a three-phase power branch, and a three-phase extension branch. The single-sided conductive terminal block 320 is fixed to the bottom of the wiring area.

[0026] The plug-in terminal block 311 has a plastic insulated main body structure and multiple plug-in conductive pins at its bottom. The terminal block 310 is mounted on the insulating surface of the single-sided conductive terminal block 320, and its plug-in conductive pins pass vertically downward through the pre-set sockets on the single-sided conductive terminal block 320 and communicate with the conductive path inside the single-sided conductive terminal block 320, thereby realizing electrical connection.

[0027] The plug-in terminal block 311 has three types of interfaces on its terminal body: a three-phase AC power interface 312, a power module interface 313, and an expansion interface 314.

[0028] Back-to-back layout of three-phase AC power interface 312 and expansion interface 314: as follows Figure 3 As shown, the three-phase AC power interface 312 and the expansion interface 314 are respectively located on opposite sides of the terminal body, forming a "back-to-back" layout. The three-phase AC power interface 312 faces outwards and is used to directly connect to the three-phase AC wires (L1 / L2 / L3 live wire, N neutral wire, PE ground wire) from the main power supply line. The expansion interface 314 faces the other side and is used to electrically connect to the three-phase AC power interface of the wiring terminal of the next LED lamp of the same model through direct plug-in connection. This layout minimizes the current path, clarifies the wiring logic, and makes it very convenient to cascade multiple lamps on a single line.

[0029] The power module interface 313 is located on the side of the terminal body, and its lead-out end is electrically connected to the three-phase input terminal of the drive power module 200.

[0030] The bottom of the terminal body of the plug-in terminal 311 is provided with plug-in conductive pins corresponding to the above interfaces, specifically including: live wire pin, neutral wire pin, and ground wire pin (corresponding to three-phase AC power interface 312); live wire power pin, neutral wire power pin, and ground wire power pin (corresponding to power module interface 313); and live wire extension pin, neutral wire extension pin, and ground wire extension pin (corresponding to extension interface 314).

[0031] When installing a single lamp, simply insert the three-phase power wires of the main power supply line into the three-phase AC power interface 312 of the plug-in terminal block 311 (e.g., using spring clips or screw clamps). AC power flows in from the interface, passes through the internal conductor and the bottom plug-in conductive pins, and is transmitted to the three-phase main path of the single-sided conductive terminal block 320. Then, the AC power is output to the drive power module 200 via the three-phase power branch and the power module interface 313, where it is converted to DC power to illuminate the lamp source module 500.

[0032] When multiple lamps need to be installed in parallel (e.g., 10 lamps above a 50-meter-long production line), operators do not need to run separate cables from the main distribution box for each lamp. The specific operation is as follows: Connect the main line to the three-phase AC interface 312 of the first lamp. Then, take a short jumper wire (or use a male-female connector), insert one end into the expansion interface 314 of the first lamp, and the other end into the three-phase AC interface of the second lamp. Continue this process, cascading all lamps together. In this way, while the first lamp supplies power to itself, it also transmits three-phase AC power losslessly to the second lamp through the three-phase expansion branch inside its internal single-sided conductive terminal block 320, achieving cascaded power supply for multiple lamps. The entire wiring process requires no additional external junction boxes or splitters, greatly simplifying the installation process and improving wiring neatness and the reliability of the lighting system.

[0033] Example 2 Please see Figures 1 to 3 As shown, this embodiment further optimizes the structure of the integrated mounting cavity 100 based on embodiment one.

[0034] To facilitate wiring operations, an operation window 111 is provided on the back of the integrated mounting cavity 100. The position of the operation window 111 corresponds to the position of the wiring ports of the wiring module 300 (i.e., the wiring holes of the three-phase AC power interface 312, the power module interface 313, and the expansion interface 314). In this way, the operator can directly insert, plug, crimp, or disassemble the AC wires by reaching into the operation window 111 without disassembling the entire integrated mounting cavity 100, greatly improving the convenience of installation and maintenance.

[0035] Furthermore, to further enhance electrical isolation and installation stability, the integrated mounting cavity 100 can be mounted onto the lamp source module 500 via an insulating plate 600. This insulating plate 600 serves both as insulation and as a structural transition component. Simultaneously, both the integrated mounting cavity 100 and the insulating plate 600 are provided with corresponding wire-passing holes for safely and neatly leading the output wires of the drive power module 200 to the lamp source module 500 below.

[0036] Example 3 Please see Figures 1 to 3As shown, this embodiment describes the internal structure of the single-sided conductive terminal block 320 and its cooperation with the plug-in terminal block 311.

[0037] The single-sided conductive terminal block 320 has multiple sockets precisely opened at the positions of each plug-in conductive pin, including live wire socket, neutral wire socket, ground wire socket, live wire power socket, neutral wire power socket, ground wire power socket, live wire extension socket, neutral wire extension socket and ground wire extension socket.

[0038] The single-sided conductive terminal block 320 has different conductive paths formed inside by copper foil etching, including a three-phase main path with an equal conductive surface width, a three-phase power supply branch, and a three-phase extension branch. The three-phase power supply branch and the three-phase extension branch are electrically connected to the three-phase main path, forming a stable one-in-two-out current splitting structure.

[0039] To prevent phase-to-phase short circuits under high voltage and high current, the aforementioned three-phase main circuit, three-phase power supply branch circuit, and three-phase extension branch circuit can be arranged in layers (e.g., on different layers with insulation between them) or in parallel while maintaining a safe distance within the terminal block. Insulation strips or insulation layers are also provided between each circuit to ensure electrical safety.

[0040] It should be noted that in this embodiment, the three-phase main path, power supply branch and extension branch adopt the same width design of conductive surface. The unified line width standardizes the PCB etching process, eliminates the need for line width compensation, reduces manufacturing costs and improves yield. It breaks through the technical bias that a larger current carrying capacity requires a larger line width, and takes into account both performance and process with the equal width solution, optimizing the manufacturability and electrical life of the terminal board.

[0041] Example 4 Please see Figures 1 to 3 As shown, this embodiment adds a power selection control module 400 based on the above embodiments to achieve flexible configuration of lamp power.

[0042] Please see Figure 2 The power selection control module 400 is also mounted on the insulating surface of the single-sided conductive terminal block 320 and is electrically connected to the signal path additionally provided inside the single-sided conductive terminal block 320. The power selection control module 400 includes at least two parallel power selection branches, each branch is equipped with a DIP switch or jumper cap as a selection switch, and power setting resistors with different resistance values.

[0043] One end of the signal path of the single-sided conductive terminal block 320 is electrically connected to the power selection control module 400, and the other end extends to the edge of the terminal block to form a standard signal interface (e.g., pin header), which is plugged into the corresponding signal control terminal (e.g., female header) on the drive power module 200.

[0044] The driver power module 200 has an internal detection circuit that reads the voltage division values ​​corresponding to different resistance values ​​in the signal path to identify the power level set by the user and adjusts its output current accordingly, thereby changing the brightness (power) of the LED lamp. For example, by combining two selector switches, the user can obtain four different resistance combinations, corresponding to four power levels: 100W, 80W, 60W, and 40W.

[0045] Furthermore, the position of the power selection control module 400 is preferably aligned with the operation window 111 on the integrated mounting cavity 100. This allows maintenance personnel to directly switch between power levels on-site via the operation window 111 after the lamp is installed, without disassembling the lamp, which is extremely convenient.

[0046] Meanwhile, to avoid electromagnetic interference from three-phase AC power on the power setting signal, the signal path is strictly isolated from the three-phase main path, three-phase power supply branch and three-phase extension branch within the single-sided conductive terminal block 320 (e.g., located in different areas or layers of the PCB board), and a grounded electromagnetic shielding layer is set around the signal path or between layers to ensure the stability and accuracy of signal transmission.

[0047] In summary, the lighting fixtures provided in the above embodiments, through the synergy of the integrated mounting cavity 100, the plug-in terminal block 311 integrating input, output, and expansion interfaces, and the single-sided conductive terminal block 320, construct a new type of LED lighting fixture that is highly integrated, easy to cascade, convenient to wire, and functionally expandable. This lighting fixture fundamentally solves the problems of complex wiring, reliance on external equipment, and low reliability in existing technologies when multiple lighting fixtures are installed in parallel, demonstrating significant technological advancement and industrial practical value.

[0048] It should be noted that the above embodiments are merely preferred embodiments of the present invention, and the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention, and the scope of protection of the present invention should be determined by the scope of the claims.
