Description

Technical Field

[0001] This invention relates to the field of lighting, and more particularly to a modular control system with an input / output bus board and a luminaire having therein. Background Technology

[0002] In existing technologies, to achieve various functions such as emergency lighting and motion-sensor lighting, ordinary lighting fixtures typically require the purchase of control systems with different functions, which are then connected together via series and parallel wiring to realize the functions of the lighting fixtures. This results in arbitrary installation locations for each control system, complex wiring, and frequent product mismatches during upgrades of different functional modules. Customers also face challenges in quickly replacing or repairing functions, leading to low flexibility. Furthermore, customers need to store lighting fixtures with different functions, resulting in significant warehousing pressure.

[0003] On the other hand, most lighting fixtures on the market currently have only one driver driving one load. If the driver fails, the entire fixture needs to be replaced, resulting in high replacement and maintenance costs. Essentially, the lifespan of the driver determines the lifespan of the entire fixture. Therefore, lighting fixtures place high demands on the driver. This is especially true for stadium lighting, where installation heights are very high, making replacement and maintenance extremely difficult and requiring high driver reliability. However, commercially available driver power supplies often fail to meet these high user expectations, leading to frequent driver failures and replacements. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a modular control system with an input / output bus board and a lighting fixture incorporating it. The input / output bus board, in the form of a printed circuit board, solves the wiring problem and allows for flexible configuration of the modular control system. The technical solution is as follows:

[0005] On one hand, the present invention provides a modular control system with an input / output bus board, which includes a support plate, an input bus board and an output bus board disposed on the support plate, and one or more power modules mounted on the input bus board and the output bus board;

[0006] The input bus board and output bus board are wired through a printed circuit board. The power module is connected to the input bus board through a docking terminal and to the output bus board through a docking terminal.

[0007] Furthermore, the modular control system also includes a central control system module and a central control adapter board electrically connected to the input bus board, the central control adapter board being used to connect the central control system and the lighting system;

[0008] The central control system module is connected to the input bus board via a docking terminal, and is also connected to the output bus board via a docking terminal.

[0009] Furthermore, the modular control system also includes an emergency power system module and a battery for providing power in emergency lighting mode. The battery is mounted on the support plate. The emergency power system module is connected to the input bus board via a docking terminal and to the output bus board via a docking terminal.

[0010] Optionally, the central control system module, the power supply module, and the emergency power supply system module are each provided with a first docking terminal (male) and a second docking terminal (male).

[0011] The input bus board is provided with a plurality of first docking terminal female terminals that mate with the male terminals of the first docking terminals, and the output bus board is provided with a plurality of second docking terminal female terminals that mate with the male terminals of the second docking terminals.

[0012] Furthermore, the battery is also equipped with an upper cover and a lower cover to keep it in a sealed space, and the central control system module, power module, and emergency power system module are all sealed structures when connected to the input bus board and output bus board.

[0013] Preferably, the modular control system further includes a sensing system module electrically connected to the central control adapter board, the central control adapter board being used to connect the central control system, the lighting system, the emergency lighting system and the sensing system.

[0014] Furthermore, the modular control system also includes several knobs for limiting the position of the central control system module and the power module. The knobs are installed on the support plate and press against the upper surfaces of the central control system module and the power module.

[0015] The thimble can rotate horizontally relative to the support plate. When the thimble rotates to the point where it is detached from the upper surface of the central control system module and the power module, the central control system module and the power module can be pulled out and disassembled.

[0016] Furthermore, there are multiple power supply modules. The central control system module collects, analyzes, and processes the ambient temperature and the output data of each power supply module in real time, and generates adjustment commands for the power supply modules based on the processing results.

[0017] On the other hand, the present invention provides a lamp, including a base, a light-emitting panel, and a modular control system as described above, wherein the number of light-emitting panels is one or more, the light-emitting panels are disposed on the front side of the base, and the modular control system is disposed on the back side of the base.

[0018] Furthermore, the lamp also includes a bracket fixedly connected to the base, the bracket being used to encapsulate the modular control system.

[0019] Furthermore, the lamp also includes lenses for controlling the light emission angle, the number of which is the same as the number of light-emitting panels, and the lenses are mounted on the light-emitting surface of the light-emitting panels.

[0020] The beneficial effects of the technical solution provided by this invention are as follows:

[0021] a. The input terminals are integrated into the input bus board, and the output terminals are integrated into the output bus board.

Detailed Implementation

[0038] 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 of the present invention. 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 should fall within the scope of protection of the present invention.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0040] The concept of this invention includes: First, using an input / output bus board to achieve interconnection between the input and output terminals; Second, using a modular control system as a carrier to achieve functional integration, eliminating the hassle of wiring between functions and the convenience of autonomous selection of modular functions; Third, using plug-in terminals to achieve modular assembly of the control system.

[0041] In one embodiment of the present invention, a modular control system with an input / output bus board is provided, such as... Figure 3 and Figure 4 As shown, the modular control system includes a support plate 52, an input bus board 37 and an output bus board 42 mounted on the support plate 52, and one or more power modules 21 mounted on the input bus board 37 and the output bus board 42; Figure 1 and Figure 2 As shown, the input bus board 37 and output bus board 42 are wired via printed circuit boards. The power module 21 is connected to the input bus board 37 and the output bus board 42 via mating terminals. Specifically, the mating terminals include male and female terminals. In a preferred embodiment for connecting the power module 21 to the input bus board 37 and output bus board 42, the input bus board 37 and output bus board 42 have female mating terminals, while the power module 21 has two male mating terminals. One (first male mating terminal 72) is connected to the female mating terminal (first female mating terminal 39) on the input bus board 37, and the other (second male mating terminal 75) is connected to the female mating terminal (Dürer female mating terminal 45) on the output bus board 42. Figure 5 As shown.

[0042] like Figure 3As shown, the number of power modules 21 is two, but the present invention does not limit the number. For example, if the output power of a single power module 21 is 50W, and the customer's output power requirement is 50W, then only one power module 21 needs to be installed; if the customer's output power requirement is 150W, then... Figure 3 Based on this, a power module 21 is added, and the lengths of the input bus board 37 and the output bus board 42 are increased to add an additional pair of first mating terminal females 39 and second mating terminal females 45 (a longer support plate 52 may need to be made).

[0043] In a preferred embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the modular control system also includes a central control system module 19 and a central control adapter board 57 electrically connected to the input bus board 37. The central control adapter board 57 is used to connect the central control system and the lighting system, that is, the central control system can control the operation of the lighting system. The central control system module 19 is connected to the input bus board 37 through a docking terminal and to the output bus board 42 through a docking terminal. The central control system module 19 is also provided with a first docking terminal male terminal 72 and a second docking terminal male terminal 75, the same as the power supply module 21.

[0044] In a preferred embodiment of the present invention, the modular control system also has an emergency function. Such a modular control system further includes an emergency power system module 25 and a battery 65 for providing power in emergency lighting conditions. The battery 65 is disposed on the support plate 52. The emergency power system module 25 is connected to the input bus board 37 and the output bus board 42 through a docking terminal. In non-emergency lighting conditions, an external AC power source charges the battery 65. When the external AC power source fails, the emergency power system module 25 is activated, and the battery 65 provides power to the lighting load.

[0045] As described above, it is connected to the input bus board 37 via a docking terminal and to the output bus board 42 via a docking terminal. See the specific structure for details. Figure 5 The central control system module 19, power supply module 21, and emergency power supply system module 25 are each equipped with a first male terminal 72 and a second male terminal 75. The input bus board 37 has several first female terminals 39 that mate with the first male terminal 72, and the output bus board 42 has several second female terminals 45 that mate with the second male terminal 75. A schematic diagram illustrating the male-female connection of the input terminals (male terminal 72 and female terminal 39) and the output terminals (male terminal 75 and female terminal 45) is shown below. Figure 5As shown. In summary, the input bus board 37 can integrate the input terminals into one unit, enabling interconnection between all ports; the output bus board 42 can integrate the output terminals into one unit, enabling interconnection between all ports; different types of control systems can be designed according to functional requirements (besides the necessary central control system module 19 and power supply module 21). For example, an emergency power supply system module 25 and battery 65 can be added according to the needs of emergency lighting, and a sensing system module 35 can be added according to sensing requirements (see below for details). Therefore, customers can stock modular systems, saving warehousing costs. Furthermore, the modular control system interfaces with the input and output bus boards through male and female connectors, ensuring strong compatibility.

[0046] See invention for details Figure 9 Multi-power module 21 (i.e. Figure 9 The working principle of the lighting system (multiple drive power supplies in the system) is as follows: The neutral wire (N) and the live wire (L) are connected through the terminals soldered to the main board. The main board has a high-voltage bus (input bus board 37) and a low-voltage bus (output bus board 42). All connections are made through the traces on the main board (PCB circuit board), eliminating the hassle of wire routing, resulting in a neat appearance and reliable connections. The power modules are electrically connected by connecting the female terminals on the input bus board and the output bus board to the male terminals on the module power supply. This reduces the number of wire connections and facilitates maintenance. The central control system module 19 (i.e. Figure 9 The central processing unit (CPU) monitors the ambient temperature, the temperature of key components, and the output of each module in real time to ensure that each module's power supply operates at its optimal state. The CPU collects, analyzes, and processes module and load data in real time, then feeds the processed data back to the driver to adjust the operating state of the power supply module 21 in real time. This achieves energy saving, improves driver reliability, and extends driver lifespan. The modular design easily enables redundancy. If the operating temperature of one module's power supply exceeds the design value, the central controller can reduce the power output of that module and increase the output of other modules. Due to the redundancy design of the module power supplies, even with increased output power, the reliability of the module power supplies is maintained, thus improving overall reliability. This also does not affect the light output of the entire lamp.

[0047] In stadium lighting, where luminaires are often tens of meters high, a malfunctioning driver causing the entire fixture to stop working can result in repair costs exceeding the price of a new fixture. The lifespan of a luminaire is largely determined by its driver. The driver accounts for only about 15% of the overall value of a luminaire. Doubling the driver's lifespan directly doubles the luminaire's lifespan; therefore, extending the driver's lifespan significantly extends the luminaire's lifespan.

[0048] To prevent electric shock accidents, the battery 65 is also equipped with an upper cover 31 and a lower cover 63 to keep it in a sealed space. The central control system module 19, power module 21, and emergency power system module 25 are all sealed structures when connected to the input bus board 37 and the output bus board 42. In one embodiment of the present invention, the specific implementation method is as follows: a plurality of lower covers 63 are fixedly arranged on the support plate 52. The central control system module 19, power module 21, emergency power system module 25, and battery 65 are respectively arranged on the corresponding lower cover 63. Except that the battery 65 and the upper cover 31 are separate structures, the other central control system module 19, power module 21, emergency power system module 25 and the upper cover 31 are all integrated structures.

[0049] In a preferred embodiment of the present invention, the modular control system further has a sensing function. Such a modular control system also includes a sensing system module 35 electrically connected to the central control adapter board 57. The central control adapter board 57 is used to connect the central control system, the lighting system, the emergency lighting system, and the sensing system. Specifically, as follows... Figure 1 or Figure 3 As shown, the support plate 52 is also provided with a sensor bracket 54, which is used to install the central control adapter plate 57 and the sensor system module 35.

[0050] In a preferred embodiment of the present invention, the control system is modular, with modules installed independently. The control system of the present invention employs a printed circuit board-type input / output bus board and uses male-female terminal blocks for connection, eliminating the tedious steps of manual wiring and effectively preventing missed or incorrect connections. The modular control system of this embodiment has a limiting structure, namely a latch 16, for each module (central control system module 19 and power module 21, and may also include emergency power system module 25 and battery 65). The latch 16 is installed on the support plate 52 and pressed against the upper surface of each module to ensure that the male terminal of each module does not detach from the female terminal on the bus board. To replace or remove a module, simply rotate the corresponding latch 16 horizontally to disengage it from the upper surface of the module, allowing the module to be pulled out. Similarly, after inserting a new module, rotate the corresponding latch 16 horizontally until it abuts against the upper surface of the module. This greatly improves the efficiency of maintenance and replacement of the central control system module 19, power module 21, emergency power system module 25, or battery 65.

[0051] In one embodiment of the present invention, a lamp is provided, such as... Figure 6-8 As shown, the lamp includes a base 9, a light-emitting panel 11, and a modular control system 6 as described above. The number of light-emitting panels 11 is one or more (not limited to). Figure 6(In the case of two), the light-emitting panel 11 is disposed on the front of the base 9, and the modular control system 6 is disposed on the back of the base 9.

[0052] In a preferred embodiment of the present invention, the lamp further includes a bracket 2 fixedly connected to the base 9 and a lens 14 for controlling the light emission angle. The bracket 2 is used to encapsulate the modular control system 6, and the encapsulated structure is as follows: Figure 8 As shown; the number of lenses 14 is the same as the number of light-emitting panels 11, and the lenses 14 are mounted on the light-emitting surface of the light-emitting panels 11, and the structure after mounting is as follows. Figure 7 As shown. Preferably, as Figure 7 As shown, the base 9 is also provided with an opening structure for avoiding the sensing bracket 54. Figure 7 (The square structure on the left side of the middle).

[0053] The working principle and operation process of the lamp in this embodiment of the invention are as follows: The input bus board of the modular control system has female terminals with uniform spacing, and all terminals are connected to each other; the output bus board has female terminals with uniform spacing, and all terminals are connected to each other; the first male terminal and the second male terminal of the central control system, power module, and emergency power system are connected to the first female terminal of the input bus board and the second female terminal of the output bus board, respectively, to realize the control of other systems.

[0054] This invention utilizes a printed circuit board-type input / output bus board to solve wiring problems, and can flexibly configure the number of power modules and adapt to emergency lighting system modules. The control system is highly modular, and each module is highly integrated.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
