[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0046] Aiming at the problems of the complex circuit structure of the lighting device and the long software integrated development cycle in the existing solution, the present application discloses a dynamic flowing water function circuit that uses pure hardware and a conventional simple circuit combination to form a dynamic control function. The circuit structure is simple, the component integration degree is low, and the dynamic effect can be achieved without software development.

[0047] The embodiment of the present application discloses a dynamic flowing water function circuit. Refer to Figure 1 , this circuit may include: a linear voltage regulator 10, an oscillation circuit 20, and a digital logic device 30.

[0048] Regarding the linear voltage regulator 10, the input terminal of the linear voltage regulator 10 is used to obtain the input current PowerSupply, and the output terminal of the linear voltage regulator 10 is used to provide a current signal after linearly regulating the input current Power Supply. The linear voltage regulator 10 is an electronic device that achieves a stable voltage output by adjusting linear elements (such as resistors, transistors, etc.) in the circuit. The linear voltage regulator 10 operates based on the principle of negative feedback. It compares the voltage at the output terminal with the reference voltage and adjusts the circuit parameters according to the comparison result to maintain the stability of the output voltage within the required range. The linear voltage regulator 10 can be regarded as a regulating valve that controls the flow of voltage to maintain voltage stability. The linear voltage regulator 10 adjusts the voltage through linear elements (such as resistors), so compared with the switching voltage regulator, it usually has lower output noise and fluctuations and has better responsiveness to load changes.

[0049] There are various types of linear voltage regulators 10. According to different classification criteria, they can be classified into the following types:

[0050] Classification by connection method:

[0051] Series linear voltage regulator 10: When an adjustment element is connected in series with the load, a series linear voltage regulator 10 is formed. In this type, the load voltage is regulated by controlling the voltage drop across the element.

[0052] Parallel linear voltage regulator: The parallel linear voltage regulator is a voltage regulator in which the path element is connected in parallel with the load. It controls the current flowing through the path element to maintain a constant voltage in the parallel linear voltage regulator 10.

[0053] Classification by output voltage type:

[0054] Fixed-output voltage regulator: This type of voltage regulator provides a preset fixed output voltage, and common standard voltage values include 3.3V, 5V, 12V, etc. They are usually used in applications that require specific voltages, simplifying the circuit design.

[0055] Adjustable-output voltage regulator: The adjustable-output voltage regulator allows users to set the required output voltage by connecting an external resistor or potentiometer. This type of voltage regulator provides higher flexibility and is suitable for applications that require multiple different voltages.

[0056] Classification by function and principle:

[0057] Positive adjustable voltage regulator: A typical model is the LM317 voltage regulator IC, and its output voltage can be adjusted between 1.2V and 37V.

[0058] Negative adjustable voltage regulator: This type of voltage regulator is used to provide a negative voltage output.

[0059] Fixed-output voltage regulator: For example, the 78XX series voltage regulator IC. Among them, 7805 is a commonly used fixed-voltage regulator with a 5V output.

[0060] Tracking voltage regulator: Used to provide an output voltage proportional to the reference voltage.

[0061] Floating voltage regulator: Can provide a stable output voltage at different power supply voltages.

[0062] Classification by conduction component technology:

[0063] NPN-Darlington, NPN, PNP, PMOS, and NMOS voltage regulators: These voltage regulators are based on different conduction component technologies and have different minimum voltage differences and quiescent current characteristics.

[0064] Classification by power rating:

[0065] Standard linear voltage regulator: Suitable for low to medium power applications, with a power range generally from a few hundred milliwatts to a few watts.

[0066] High-power voltage regulator: Designed to provide a higher output current, usually above several tens of amperes. These voltage regulators may require heat sinks to handle higher heat dissipation.

[0067] Those skilled in the art can select a suitable linear voltage regulator as the linear voltage regulator for the dynamic pipelining function circuit in this application according to the circuit design requirements.

[0068] Regarding the oscillation circuit 20, the input end of the oscillation circuit 20 is connected to the output end of the linear voltage regulator 10 and is used to provide a clock signal to the digital logic device 30. The working principle of the oscillation circuit 20 can be explained by the concept of positive feedback. In an oscillation circuit, the input signal of the oscillation circuit is amplified by an amplifier and then fed back to the input end of the amplifier through a feedback network and amplified again. In this way, a positive feedback closed loop is formed. When the gain of the amplifier is greater than the attenuation of the feedback network, the system will generate oscillations. Specifically, at the beginning of the oscillation circuit 20, due to tiny noise or interference, the amplifier will amplify these signals and feed them back to the input end through the feedback network. After multiple feedback amplifications, the amplitude of the signal will continuously increase until it reaches the saturation point of the amplifier. In the saturation state, the amplitude of the signal will start to decrease until the gain of the amplifier is large enough again to maintain the oscillation. In this way, a periodic oscillation signal is formed. In the oscillation circuit 20, the charge on the capacitor plates, the current passing through the coil, and the magnetic and electric fields associated with the current and charge all change periodically. This phenomenon is called electromagnetic oscillation. Oscillating current is an alternating current, an alternating current with a very high frequency. It cannot be generated by rotating a coil in a magnetic field and can only be generated by the oscillation circuit 20. The oscillation circuit 20 has a wide range of applications in many fields such as measurement, automatic control, radio communication, and remote control. For example, a sine wave oscillator is often used as the input signal of an amplifier to observe the distortion of the output waveform and measure the voltage amplification factor and frequency characteristics of the amplifier. In radio communication, high-frequency sine signals are often used as the "carrier" of audio signals for long-distance transmission.

[0069] The types of the oscillation circuit 20 mainly include the following several:

[0070] RC oscillation circuit: Composed of a capacitor and a resistor, it can generate a periodic oscillation signal.

[0071] LC oscillation circuit: Composed of an inductor and a capacitor, it can also generate a periodic oscillation signal.

[0072] Excitation oscillation circuit: Composed of an amplifier and an oscillation element, it can generate a periodic oscillation signal.

[0073] Sine oscillation circuit: An oscillation circuit that can generate sine or cosine waveform signals. Sine wave oscillators have a wide range of applications in many fields such as measurement, automatic control, radio communication, and remote control.

[0074] Relaxation oscillation circuit: The generated signal waveform has mutations, such as triangular waves, rectangular waves, square waves, or sawtooth waves, etc.

[0075] In addition, there are also some special types of oscillation circuits, such as a double triode multivibrator circuit, etc.

[0076] In this solution, the specific type of the oscillation circuit 20 can be selected according to the design requirements of the dynamic pipelining functional circuit.

[0077] Regarding the digital logic device 30, the clock signal input terminal of the digital logic device 30 is connected to the output terminal of the linear voltage regulator 10, the current input terminal of the digital logic device 30 is connected to the output terminal of the linear voltage regulator 10, the control signal input terminal of the digital logic device 30 is used to obtain an analog steering signal, and the output terminal of the digital logic device 30 is used to provide a control signal for the lighting circuit.

[0078] Digital logic devices 30 are circuits that implement digital signal logic operations and operations based on the binary principle. They are mainly divided into combinational logic circuits and sequential logic circuits. The logic function of a combinational logic circuit is independent of time, that is, it does not have memory and storage functions, while the output result of a sequential logic circuit is not only related to the input logic but also controlled by timing. The digital logic device 30 in this solution is a sequential logic circuit.

[0079] According to functional characteristics, digital logic devices 30 can be further classified into gate circuits, latches and flip-flops, encoders and decoders, multiplexers and multi-feedback, counters and clocks, etc. In circuit design, according to different processes, logic devices can also be divided into types such as Bipolar (bipolar), CMOS (complementary metal oxide semiconductor), and BiCMOS. When selecting and using digital logic devices 30 in a dynamic pipelining functional circuit, the specific type of digital logic device 30 can be selected according to design requirements.

[0080] This application designs a dynamic pipelining functional circuit. The circuit includes three circuit modules: a linear voltage regulator 10, an oscillation circuit 20, and a digital logic device 30. The linear voltage regulator 10 supplies power to the subsequent oscillation circuit 20 and digital logic device 30. The oscillation circuit 20 provides a timing control signal for the digital logic device 30. Under the action of the timing control signal and the analog steering signal voltage, the digital logic device 30 can generate a displacement level with a required time interval at the output terminal of the digital logic device 30, and use this displacement level as the control signal for the lighting circuit to control the lighting circuit to achieve the dynamic pipelining effect. It can be seen that the circuit structure of this solution is simple, easy to develop and debug, has a low cost, and does not require software development. The effect of adjusting the speed of the lighting change of the lighting circuit can be achieved by appropriately changing the sizes of the resistors and capacitors in the circuit.

[0081] In the technical solution disclosed in this embodiment, the specific structure of a linear voltage regulator 10 circuit is disclosed. Refer to Figure 2 , the linear voltage regulator 10 circuit disclosed in this embodiment may include:

[0082] Linear chip 11, first voltage stabilizing capacitor C1, diode D1, and second voltage stabilizing capacitor C2;

[0083] Among them, the first voltage stabilizing capacitor C1 and the diode D1 are connected to the input end of the linear chip 11; the second voltage stabilizing capacitor C2, and the second voltage stabilizing capacitor C2 is connected to the output end of the linear chip 11.

[0084] The linear chip 11 in the linear voltage regulator 10 refers to a chip that can stably convert the input voltage into the required output voltage. They mainly achieve voltage conversion through a buck method and have high-quality output and low-noise characteristics. For example, it can be LT1790ACS6-5 chip, LM317 chip, LM7805 chip, AMS1117 chip, ME6209A30PG chip, HT7133 chip, HT7533 chip, and HT7536-1 chip, etc. The function of the first voltage stabilizing capacitor C1 is to stabilize the input voltage of the linear chip 11, the function of the diode D1 is to prevent current from flowing back into the power supply, and the function of the second voltage stabilizing capacitor C2 is to stabilize the output voltage of the linear chip 11. In Figure 2 In the shown scheme, the current output by the power supply passes through the diode D1, is stabilized by the first voltage stabilizing capacitor C1, the stabilized current enters the linear chip 11, after being linearly voltage-stabilized by the linear chip 11, it is output from its output end, and the output current is stabilized by the second voltage stabilizing capacitor C2.

[0085] In this embodiment, the first voltage stabilizing capacitor C1 and the second voltage stabilizing capacitor C2 can be a single capacitor, or can include multiple parallel capacitors. For example, see Figure 3 , in this embodiment, the first voltage stabilizing capacitor C1 can include the parallel capacitors C11 and C12, and the second voltage stabilizing capacitor C2 can include the parallel capacitors C21 and C22. The sizes of the capacitors C11, C12, C21, and C22 can be selected according to user needs. For example, the capacitance values of the capacitors C11 and C21 can be 4.7uF, and the capacitance values of the capacitors C12 and C22 can be 100nF.

[0086] In the technical solution disclosed in this embodiment, the specific structure of an oscillation circuit 20 is disclosed. See Figure 4 , the oscillation circuit 20 disclosed in this embodiment can include:

[0087] First switching transistor Q1 and second switching transistor Q2, and the second ends of the first switching transistor Q1 and the second switching transistor Q2 are grounded;

[0088] First capacitor C3, and the first capacitor C3 is arranged between the control end of the first switching transistor Q1 and the first end of the second switching transistor Q2;

[0089] A second capacitor C4, where the second capacitor C4 is disposed between a first end of the first switching transistor Q1 and a control end of the second switching transistor Q2;

[0090] A first resistor R1, where a first end of the first resistor R1 is connected to an output end of the linear voltage regulator 10, and a second end of the first resistor R1 is connected to the first end of the first switching transistor Q1;

[0091] A second resistor R2, where a first end of the second resistor R2 is connected to the output end of the linear voltage regulator 10, and a second end of the second resistor R2 is connected to the control end of the second switching transistor Q2;

[0092] A third resistor R3, where a first end of the third resistor R3 is connected to the output end of the linear voltage regulator 10, and a second end of the third resistor R3 is connected to the control end of the first switching transistor Q1;

[0093] A fourth resistor R4, where a first end of the fourth resistor R4 is connected to the output end of the linear voltage regulator 10, and a second end of the fourth resistor R4 is connected to the first end of the second switching transistor Q2.

[0094] In the technical solution disclosed in this embodiment, the types of the first switching transistor Q1 and the second switching transistor Q2 can be selected according to requirements. For example, the first switching transistor Q1 and the second switching transistor Q2 can be triodes or metal-oxide-semiconductor field-effect transistors. When the switching transistor is a triode, the collector of the triode is the first end of the switching transistor, the emitter of the triode is the second end of the switching transistor, and the base of the triode is the control end of the switching transistor. When the switching transistor is a metal-oxide-semiconductor field-effect transistor, the correspondence between the three ends (gate, source, drain) of the switching transistor and the control end, the first end, and the second end of the switching transistor can refer to that of the triode. In the technical solution disclosed in the above embodiment, the functions of the first resistor R1, the second resistor R2, the third resistor R3, and the fourth resistor R4 are all to step down the voltage, and the functions of the first capacitor C3 and the second capacitor C4 are to isolate direct current. Figure 3The disclosed oscillator circuit 20 charges and discharges a capacitor through a resistor and controls the conduction / turn-off of a switching transistor, thereby generating a square wave with a certain period at the first ends of the first switching transistor Q1 and the second switching transistor Q2, and providing a timing signal to the digital logic device 30. Specifically, when the first resistor R1 and the fourth resistor R4 have a resistance value of 1 KΩ, the second resistor R2 and the third resistor R3 have a resistance value of 30 KΩ, and the capacitance values of the first capacitor C3 and the second capacitor C4 are 1 uF, the period of the square wave output by the first switching transistor Q1 is: TCLK = 2 * 0.7 * R2 * C1, where R2 in the formula refers to the resistance value of the second resistor R2, and C1 refers to the capacitance value of the first capacitor C3. Figure 3 In this case, both the first switching transistor Q1 and the second switching transistor Q2 can be NPN transistors. In addition to the astable multivibrator composed of the Figure 3 dual NPN transistors shown, the oscillator circuit 20 can also be an astable multivibrator composed of an operational amplifier, an astable multivibrator composed of a Schmitt trigger, an astable multivibrator composed of a CMOS inverter, an astable multivibrator composed of a 555 integrated circuit, or a multivibrator composed of complementary transistors.

[0095] In the technical solution disclosed in this embodiment, the digital logic device 30 can be implemented using a digital logic chip. At this time, the CLK port of the digital logic chip serves as the clock signal input terminal of the digital logic device 30, the output pin of the digital logic chip serves as the output terminal of the digital logic device 30, the CLR port of the digital logic chip serves as the control signal input terminal of the digital logic device 30, and the power interface of the digital logic chip serves as the current input terminal of the digital logic chip. The specific type of the digital logic chip can be selected according to user requirements. For example, in the technical solution disclosed in this embodiment, the digital logic chip can be a chip with the model number 74LS164N. This chip supports 8 output pins and can provide control signals for 8 light-emitting elements simultaneously.

[0096] In the technical solution disclosed in this embodiment, the dynamic pipelining function circuit can be integrated with a signal generator. The output terminal of the signal generator is connected to the CLR port of the digital logic chip for providing an analog steering signal to the digital logic chip. Of course, the signal generator can also be set independently of the dynamic pipelining function circuit. Figure 5As shown, in the technical solution disclosed in this embodiment, a control switch J1 can also be provided between the signal generator and the CLR port of the digital logic chip, and whether the signal generator provides an analog steering signal to the digital logic chip is controlled by the control switch G1. Among them, an inverter is provided at the CLR port of the digital logic chip 74LS164N, and the inverter is used to reverse-process the obtained analog steering signal. When the digital logic chip detects that the signal voltage (~CLR) detected by the CLR pin is at a low level, and at the same time at each rising edge of the timing (CLK), the output terminals (QA-QH) sequentially output high levels. By using this high-level signal that changes periodically to control the on and off sequence of each light-emitting element in the lighting circuit, a dynamic flowing water effect can be achieved.

[0097] In this embodiment, the lighting circuit can also be used as part of the dynamic flowing water function circuit. At this time, referring to Figure 6 As shown, the lighting circuit includes:

[0098] N light-emitting units 400, the input end of each light-emitting unit is correspondingly connected to an output pin of the digital logic chip, and N is a positive integer not less than 1;

[0099] Referring to Figure 6 As shown, the light-emitting unit includes:

[0100] A light-emitting element, the input end of the light-emitting element is connected to the power supply, and the light-emitting element can be an LED diode;

[0101] A third switching tube Q3, the first end of the third switching tube Q3 is connected to the output end of the light-emitting element, and the second end of the third switching tube Q3 is grounded;

[0102] A fourth switching tube Q4Q4, the first end of the fourth switching tube Q4 is connected to the control end of the third switching tube Q3, the second end of the fourth switching tube Q4 is grounded, and the control end of the fourth switching tube Q4 is connected to the second end of the third switching tube Q3 through a voltage-dividing resistor.

[0103] In addition to the above-mentioned light-emitting element, third switching tube Q3 and fourth switching tube Q4, a plurality of resistors can also be provided in the light-emitting unit summary. For example, referring to Figure 6, may include resistor R4, resistor R6, resistor R7, resistor R8, and resistor R9. Among them, the first end of resistor R4 is connected to the output pin line of the digital logic chip, the second end of resistor R4 is connected to the control end of the third switching transistor Q3, the first end of resistor R6 is connected to the second end of the third switching transistor Q3, the second end of resistor R6 is grounded, the first end of resistor R7 is connected to the control end of the third switching transistor Q3, the second end of resistor R7 is grounded, the first end of resistor R8 is connected to the output end of the light-emitting element, the second end of resistor R8 is connected to the first end of the third switching transistor Q3, the first end of resistor R9 is connected to the control end of the fourth switching transistor Q4, and the second end of resistor R9 is connected to the first end of resistor R6.

[0104] In the above solution, after the circuit is powered on, the signal generator generates an analog turn signal. During the high-level period of the signal, the signal is inverted through the CLR pin of the digital logic chip. Under the control of the inverted signal, the output pin of the digital logic chip outputs a low-level signal, and the controlled third triode is not turned on, and the light-emitting element remains off; when the analog signal generated by the digital logic chip is at a low level, at each rising edge of "CLK", the output pin of the digital logic chip of the digital logic chip starts to output a high level in sequence, and the controlled triodes are lit in sequence to produce a dynamic effect.

[0105] In the technical solution disclosed in this embodiment, in order to facilitate the replacement and maintenance of the lighting circuit, the lighting circuit is connected to the digital logic chip through a terminal block. Through the terminal block, the quick plugging and unplugging of the lighting circuit can be realized.
