[0026] The present invention will be described in detail below through specific embodiments to enable those skilled in the art to easily implement the present invention based on the disclosure herein. The embodiments described below are merely exemplary embodiments of the present invention, and not all embodiments thereof. All other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in this specification can be combined with each other.

[0027] To address the problems of existing technologies, the inventors discovered that current LED aquarium lighting combinations are fixed, lack flexibility, are unsuitable for the growth of different fish and aquatic plants, and have poor aesthetic appeal. Therefore, the inventors considered designing an LED light controller and LED aquarium light with multiple variable combination modes to meet the actual needs of aquarium use.

[0028] Figure 1 This illustration shows an exemplary system architecture of a specific embodiment of the LED light controller of this utility model. The LED light controller of this embodiment includes a microprocessor 101, a storage module 102 connected to the microprocessor, and a multi-channel drive module 103. The storage module 102 stores at least one lighting mode parameter, for example, 2-10 parameters. The number of parameters can be set according to specific user needs, and this embodiment does not limit this. This embodiment uses the storage module 102 storing two lighting mode parameters as an example, namely, lighting mode 1 and lighting mode 2.

[0029] The microprocessor 101 includes multiple PWM module units. In this embodiment, the number of PWM module units may be, for example, five. The microprocessor 101 controls the five PWM module units to output five PWM signals corresponding to the mode parameters selected by the user. The PWM signals may be 256-level PWM dimming drivers. Figure 2 A schematic diagram of an exemplary circuit structure of the microprocessor 101 in the LED lamp controller of this embodiment is shown.

[0030] In this embodiment, the multi-channel drive module 103 may include five field-effect transistor units that are connected one-to-one with the above-mentioned PWM module units. These five field-effect transistor units are used to connect one-to-one with five LEDs respectively, and to drive and control the five LEDs respectively. Figure 3The diagram shows a circuit structure diagram of one of the field-effect transistor (FET) units in the multi-channel drive module 104 of the LED lamp controller in this embodiment. After receiving their respective PWM signals from the PWM module unit, the five FET units generate corresponding PWM drive signals to drive their respective LEDs, enabling the five LEDs to turn on according to the selected lighting mode parameters, thereby achieving the desired lighting effect. Thus, the LED lamp controller in this embodiment can switch between different lighting modes according to the user's selection of lighting mode parameters, meeting the user's actual needs.

[0031] In the microprocessor 101 of the LED lamp controller of this utility model, the PWM module unit outputs the PWM signal, and the field-effect transistor unit generates the PWM drive signal to drive the LED lamp. This utility model creatively combines multiple PWM module units to correspond to the selected lighting mode parameters, and the microprocessor 101 controls and starts the lighting mode, realizing the selection and switching of multiple lighting modes, so as to meet the user's refined and personalized lighting needs.

[0032] The LED light controller in this embodiment may further include a control panel 104. The control panel 104 is equipped with a touch-sensitive switch button connected to the microprocessor 101 and two lighting mode buttons (not shown in the figure). The switch button is used to perform power on / off operations, and the two lighting mode buttons correspond to lighting mode 1 and lighting mode 2, respectively. It should be noted that the two lighting mode buttons in this embodiment are merely an example; in actual implementation, multiple buttons can be set as needed to correspond to the number of lighting modes. Of course, those skilled in the art can easily conceive and implement that the number of lighting mode buttons does not necessarily correspond one-to-one with the number of lighting modes; for example, one lighting mode button can control multiple lighting modes.

[0033] In addition, the control panel 104 may also be equipped with indicator lights (not shown in the figure) corresponding to each button, used to display the power on / off status, lighting mode 1 output status, and lighting mode 2 output status respectively, so as to achieve good human-machine information exchange. Similarly, those skilled in the art can easily conceive and implement that the number of the above indicator lights does not necessarily correspond one-to-one with the power on / off status and lighting mode, and the above indicator lights can also be replaced by a display screen. Furthermore, the above lighting mode buttons and indicator lights can also be integrated into a touch screen, which can also achieve the above technical effects. Figure 4 The diagram shows the circuit structure of each button and indicator light in the control panel of the LED light controller in this embodiment.

[0034] This embodiment of the LED light controller also includes a signal receiving module 106 and a signal level conversion module 105 connected thereto. The signal level conversion module 105 is connected to the microprocessor 101. The signal receiving module 106 receives external data signals (which may be data signals compliant with the DMX512 protocol) and transmits them to the signal level conversion module 105. In this embodiment, since the data signals transmitted by the DMX512 protocol are differential signals with extremely strong anti-interference capabilities, the signal level conversion module 105 needs to convert them into TTL level signals that the microprocessor 101 can recognize. After receiving the TTL level signal, the microprocessor 101 stores it in the storage module 102 for the generation, updating, and upgrading of lighting mode parameters. Figure 5 The circuit structure diagram of the signal receiving module 106 and the signal level conversion module 105 of the LED lamp controller in this embodiment is shown. In this embodiment, the data signal transmitted by the DMX512 protocol is also 256 levels, which matches the 256-level PWM dimming drive output by the PWM module, so the response speed is fast and the stability and reliability are good.

[0035] Specifically, the signal receiving module 106 in this embodiment can adopt a USB hot-swappable physical interface or be implemented as a wireless receiving unit. The signal receiving module 106 is used to receive external data generation, update, and upgrade signals to complete the generation, update, and upgrade of the lighting mode parameters in the storage module 102. Since the USB hot-swappable interface may experience momentarily high voltage, the signal receiving module 106 in this embodiment may also include a lightning protection and anti-static unit to prevent damage to internal components.

[0036] The LED controller in this embodiment may further include a power supply filtering and regulating module 107 and a boost filtering module 108 connected thereto. The input terminal of the power supply filtering and regulating module 107 can be connected to a 24V constant power DC power supply, for example. The first output terminal of the power supply filtering and regulating module 107 is connected to the microprocessor 101, used to convert the 24V constant power DC voltage into a stable and clean low voltage, such as 5V, for use by the microprocessor 101. The second output terminal of the power supply filtering and regulating module 107 is connected to the input terminal of the boost filtering module 108. The output terminal of the boost filtering module 108 is connected to the multi-channel drive module 103, used to boost the received stable low voltage to the voltage required by the multi-channel drive module, such as 24V, to provide sufficient power input voltage for the drive circuit, thereby satisfying the high-current drive of the constant voltage high-power MOSFET and effectively reducing the heat loss of the MOSFET. Figure 6 A schematic diagram of the power supply filtering and voltage regulation module of the LED lamp controller in this embodiment is shown. Figure 7 A schematic diagram of the circuit structure of the boost filter module of the LED lamp controller in this embodiment is shown.

[0037] In this embodiment, the output terminal of the multi-channel drive module 103 can adopt a waterproof pluggable aviation connector, with a total of six positive wires outputting five LED control channels, ensuring the safe and reliable opening and closing of the five LEDs.

[0038] This embodiment of the LED light controller conforms to international standard lighting control protocols, converting the input constant 24V DC voltage into a five-channel, adjustable 24V DC digital PWM drive signal. Furthermore, the control panel's power switch and lighting mode buttons allow for on / off control and switching between different lighting mode combinations. The signal receiving module 106's input port can be connected to a data transmitter (e.g., USB) or wirelessly received via an app, providing a foundation for subsequent data generation, updates, and upgrades, enabling a wider range of lighting mode combinations.

[0039] In one application scenario, the aforementioned LED light controller can be used for LED aquarium lights. The five LEDs can be a combination of CW (warm white / cool white) LEDs and RGB (red, green, blue) tri-color LEDs. The CW LEDs are used to adjust the color temperature, while the RGB LEDs are used to adjust the color. This allows the five LEDs to achieve different light colors or warm / cool color temperatures under different lighting mode parameters, displaying a vibrant array of colors, which is highly suitable for the ecological environment and aesthetic lighting requirements of aquariums.

[0040] The operation of the LED aquarium light is as follows: After connecting to 24V DC power, the power supply filter and voltage regulator module 107 provides a stable and clean 5V voltage to the microprocessor 101. After being powered on, the microprocessor 101 controls five PWM module units to output five PWM signals corresponding to the parameters of the mode button, according to the lighting mode selected by the user. Then, the multi-channel drive module 103 generates five corresponding PWM drive signals, which ultimately drive the five LEDs to light up. At the same time, the operating status is displayed by the corresponding indicator lights. If there is an update or upgrade data input, the microprocessor 101 can first save the update or upgrade data in the storage module 102. The corresponding indicator light will flash three times to indicate that the data has been saved and will be used for subsequent execution of the lighting mode.
