[0045] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0046] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0047] The following embodiments of the present application provide a lamp control device, which solves the problem that existing lamp controls are difficult to meet the personalized and artistic lighting needs of home users.

[0048] The new LED control system uses a combination of microcontrollers, wireless communications, sensors and other technical means to achieve multi-parameter, intelligent, and scenario-based lighting control. It can create an artistic lighting atmosphere, bring people aesthetic enjoyment, and maximize the utilization of electricity to achieve energy saving and consumption reduction.

[0049] With the continuous innovation and progress of technology, in order to meet the personalized and artistic lighting needs of home users. The structure of the lamps used is not limited to traditional bulbs, T8 lamps, ceiling lamps, flat lamps, etc. With the personalized needs, they can be made into flexible light strips, LED modules, etc., and different splicing and shaping can be performed according to the actual use scenarios. And they can be cut and extended at will to emit light. The key point of this design is how to ensure or achieve the consistency of opening and closing of these spliced ​​lamps and the consistency of dimming, toning and color after opening. Especially in the field of high-power lighting such as large-area, ceiling light curtains and centralized lighting, the consistency of opening or closing and the consistency of dimming, toning and color are particularly important.

[0050] The traditional control method is a switching power supply, a controller, and a load. The switching power supply provides a stable, high-precision constant voltage for the controller. The controller mainly provides PWM signals through wireless communication technology to achieve dimming, color adjustment, and color change of the load. Due to the limitation of the power of the switching power supply, the load is personalized and the shape changes in the high-power lighting field such as large-area use and ceiling light curtains. One controller can only correspond to one switching power supply and load. However, if it is used in a large area or in application scenarios such as ceiling light curtains, multiple controllers must be placed, which will result in the consistency of opening and closing, and the inability to open or close synchronously, and the overall synchronization cannot be achieved during dimming, color adjustment, and color change.

[0051] like Figure 1 As shown, it is a structural block diagram of the lamp control described in the embodiment of the present application. The present application proposes to adopt an amplifier (expander, repeater, transponder) control method, specifically a switching power supply, a controller, an amplifier, a load and a low-power switching power supply, that is, a controller can control multiple lamp loads through an amplifier. When the controller issues a lamp control instruction, the lamp control instruction can be transmitted to the corresponding connected load through the amplifier, so that one controller can control multiple loads at the same time, and realize the synchronization of opening, closing, dimming, color adjustment and color change. Among them, the low-power switching power supply provides a constant voltage for the controller.

[0052] The principle and implementation of a lamp control device of this embodiment will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can understand the lamp control device of this embodiment without creative work.

[0053] like Figure 2 As shown, this embodiment provides a lamp control device, the lamp control device 10 includes a control circuit 110 and a signal transmission circuit 120. The lamp control device is used to control a lamp group 20.

[0054] The control circuit 110 is communicatively connected with the signal transmission circuit 120, and is used to output at least two lamp control signals;

[0055] The signal transmission circuit 120 includes a plurality of signal transmission channels 121; each of the signal transmission channels 121 is communicatively connected with a different pin in the control circuit 110 to transmit the lamp control signal output by the corresponding pin;

[0056] The lamp group 20 includes a plurality of lamps; each of the signal transmission channels is connected to each of the lamps in one-to-one communication, and operates under the control of each lamp control signal, so that the correspondingly connected lamps can switch between different lighting effects under the control of the lamp control signal.

[0057] In an embodiment of the present application, the signal transmission circuit is an amplifier, an expander, a repeater and / or a transponder. The present application embodiment is described by taking an amplifier as an example, but the present application is not limited thereto.

[0058] Specifically, the control circuit outputs a lamp control signal, and transmits the lamp control signal to the corresponding connected lamp through each signal transmission channel, so that the corresponding connected lamp can switch different lighting effects under the control of the lamp control signal. In this way, one control circuit can control multiple lamp loads at the same time, and realize the synchronization of opening, closing, dimming, color adjustment and color change.

[0059] Amplifier: Its main function is to enhance the strength of the signal, usually working in wireless communication systems. After receiving a weak signal, it uses technical means to increase the power of the signal, and then sends it out again to cover a wider area.

[0060] Extender: Usually refers to the wireless signal extender in a wireless network. It establishes a connection with the main router wirelessly and provides another wireless signal itself, thereby expanding the coverage of the original wireless network.

[0061] Repeater: It is used for two-way forwarding of physical signals between two network nodes. It mainly completes the functions of the physical layer, such as signal duplication, adjustment and amplification, to extend the effective transmission distance of the network. Repeaters work at the first layer of the OSI model - the physical layer.

[0062] Repeater: This word can mean different things in different contexts, but in networking terms, it usually refers to a bridge or router, which are devices that forward data from one network segment to another based on the address information in the packet. They work at a higher level of the network layer.

[0063] like Figure 3As shown, the lamp control device further includes a first switching power supply 130 ; the first switching power supply 130 is communicatively connected with the control circuit 110 and is used to supply power to the control circuit 110 .

[0064] In an embodiment of the present application, the lamp control device further includes a plurality of second switch power supplies 140 ; ​​each of the second switch power supplies is respectively connected to a corresponding lamp for communication, and is used to supply power to the correspondingly connected lamp.

[0065] In another embodiment of the present application, the second switching power supply is communicatively connected to each of the signal transmission channels to supply power to the correspondingly connected lamps.

[0066] It should be noted that when the second switching power supply is connected to the respective signal transmission channels for corresponding communication, the second switching power supply can provide power to the respective electronic devices in the corresponding signal transmission channels and the corresponding connected lamps at the same time.

[0067] like Figure 4 As shown, the control circuit 110 includes a control chip 111; the control chip is used to output multiple lamp control signals through different pins.

[0068] The control chip 111 includes a plurality of first pins 1111 and second pins 1112 .

[0069] Each of the first pins 1111 is respectively communicatively connected to each of the signal transmission channels;

[0070] The second pin 1112 is communicatively connected to the first switching power supply 130 .

[0071] In one embodiment of the present application, the first pin is a PWM pin; the second pin is a VDD pin.

[0072] It should be noted that the control chip can be an MI control chip, but this application is not limited to this. Users can choose a suitable control chip according to actual needs.

[0073] In an embodiment of the present application, the lamp control signal includes one or more of a light on control signal, a light off control signal, a cool white light control signal, a warm white light control signal, and an RGB red, green, and blue control signal.

[0074] like Figure 4 As shown, the control circuit 110 further includes a driving component 112;

[0075] The driving component 112 includes a plurality of driving devices 1121 , which are respectively connected to the first pins 1111 of the control chip 111 for driving the transmission of control signals of the lamps.

[0076] In one embodiment of the present application, the control circuit 110 further includes a MOS tube component 113;

[0077] The MOS tube assembly 113 includes a plurality of MOS tubes 1131 , which are respectively connected to the driving devices 1121 for communication so as to output corresponding driving lamp control signals.

[0078] like Figure 5 As shown, in one embodiment of the present application, the signal transmission channel 121 includes an optocoupler device 1211, which is communicatively connected to different pins in the control circuit 110 to transmit the lamp control signal output by the corresponding pin to the correspondingly connected lamp.

[0079] In an embodiment of the present application, the signal transmission circuit 120 further includes a logic integrated circuit 122 and a plurality of third switch power supplies 123 .

[0080] The logic integrated circuit 122 is communicatively connected to the optocoupler devices in each of the signal transmission channels so as to transmit the lamp control signal to the corresponding lamp.

[0081] Each of the third switching power supplies is respectively connected to each device in the signal transmission circuit to provide power to each of the devices, for example, to provide power to each optocoupler device and a logic integrated circuit.

[0082] In one embodiment of the present application, the lamp is one or more of a cold white light lamp, a warm white light lamp and / or an RGB red, green and blue light.

[0083] like Figure 6 , which is a schematic diagram of the circuit principle of the lamp control device according to the embodiment of the present application. This embodiment is described by taking two loads as an example, and the loads can be increased according to actual needs, and the present application is not limited to this.

[0084] Specifically, under the action of the 3.3V power supply, the control chip M1 sends out two lamp control signals PWM_W and PWM_C through pins 8 and 9, PWM_C represents the cold white light control signal, and PWM_W represents the warm light control signal, and then transmits them to the corresponding connected amplifier circuits through driving MOS tubes U6 and U7, thereby controlling the LED load correspondingly connected to the amplifier, so that the corresponding LED lamp can switch between different lighting effects under the control of different lamp control signals, and realize the synchronization of opening, closing, dimming, color adjustment and color change.

[0085] It should be noted that Q1 and Q2 can be increased according to the actual controlled load. CW / WW represent different LED load color temperatures. In addition, there are NW and DW color temperatures, which users can choose according to actual needs.

[0086] CW: Cool White light has a color temperature of more than 7000K.

[0087] NW:Nature White 4000K.

[0088] WW:Warm White warm light 2700K.

[0089] DW: Daylight White 6000K.

[0090] like Figure 7 As shown, it is shown as Figure 6 The circuit diagram of the 5V power supply is provided in Figure 6 In the figure, the positions corresponding to the 5V power supply are all connected to this circuit to provide power supply for each electronic device.

[0091] In traditional control methods, when multiple controllers are used, there will be inconsistencies in the moment of opening and closing, dimming, color adjustment and color switching. This phenomenon will not only directly affect the quality and viewing experience of the picture, but may also have a negative impact on the audience's understanding and acceptance of the displayed content. This inconsistency will also make it difficult for viewers to concentrate, especially when playing dynamic images or displaying data charts. Unbalanced brightness distribution may cause the loss of important information, making it impossible for the audience to accurately obtain or understand the key details of the content.

[0092] This application can solve the shortcomings of the above multiple controllers through the application of one controller and multiple amplifiers. Consistency is one of the important criteria for measuring the quality of the product. It is related to whether the entire large area can effectively transmit information, meet visual aesthetic needs, and create an immersive viewing experience. This ensures that the LED large screen can present excellent and stable visual effects in various occasions.

[0093] In summary, the lighting control device described in the embodiment of the present application has the following beneficial effects:

[0094] 1. Compared with the traditional control method, this application can ensure the synchronization of opening, closing, dimming, color adjustment and color change of multiple LED loads through the application of one controller and multiple amplifiers. Especially in the field of large-area, ceiling light curtain and other concentrated lighting, the consistency of opening or closing and the consistency of dimming, color adjustment and color are particularly important. When used in a large area, it can effectively convey information, meet visual aesthetic needs and create an immersive viewing experience. This ensures that the large LED screen can present excellent and stable visual effects in various occasions, and can meet the personalized and artistic lighting needs of home users.

[0095] 2. In the traditional control method, it is relatively troublesome to replace multiple controllers when they are damaged. In the present application, it is convenient and quick to replace one controller when it is damaged.

[0096] 3. The controller is an indispensable component for realizing wireless communication, dimming, color adjustment, color switching, flashing and other functions of the load. It can realize the switching and change of different lighting effects according to different application scenarios.
