Description

Technical Field

[0001] The invention relates to the technical field of decorative light strip control systems, in particular to a decorative light strip structure with dynamic effects when powered on. Background Art

[0002] With the popularization of LED technology, decorative light strips, as a common lighting device, are widely used in various environments. Traditional LED light strip control systems mainly rely on simple current regulation methods to maintain the brightness and dynamic effects of the light strips. However, the current control and thermal management solutions in the existing technology are usually relatively simple, and lack real-time adjustment for changes in dynamic lighting effects. In order to ensure the stability and long life of the light strip, fixed current settings and heat dissipation designs are usually adopted. However, these technologies face problems such as excessive current fluctuations, excessive temperatures, and sudden increases in starting current in actual applications, which lead to system instability and may even have a negative impact on the long-term operation of the light strip.

[0003] Most of the current control in the prior art relies on simple settings and cannot make dynamic adjustments according to the real-time changes in the working state of the light strip. This results in the current being unable to adapt to the needs of different lighting effects in a timely manner when the light strip displays complex dynamic effects, and current instability or overload is prone to occur, thus affecting the normal operation of the light strip. Existing thermal effect management solutions usually rely on fixed heat dissipation designs, ignoring the changes in temperature under working conditions, which can easily cause local overheating, affect the performance of the light strip and accelerate the aging of the lamp beads. During the startup process, the traditional current increase method lacks smooth control, resulting in a sudden increase in current, which may cause damage to the power supply and circuit. In comparison, the present invention effectively solves the above problems by introducing adaptive current regulation, real-time heat flow calculation, and a smooth startup mechanism based on Lyapunov stability theory, thereby ensuring the stability, reliability and long-term service life of the light strip. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a decorative light strip structure with dynamic effects when powered on, aiming to solve the problems of excessive current fluctuation, heat accumulation and sudden current surge at startup in the prior art.

[0012] Preferably, the current control module, the thermal effect management module, and the power-on self-start module coordinate their operations through the control unit to optimize the stability and operating efficiency of the light strip.

[0013] Preferably, the current control module further includes: A genetic algorithm optimization unit for optimizing the current distribution of multiple LED light beads to achieve an optimal current regulation distribution.

[0014] Preferably, the thermal effect management module optimizes the heat distribution path of the light strip through finite element analysis technology, reduces heat accumulation, and improves the heat dissipation effect.

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a schematic diagram of the composition structure of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, in conjunction with the accompanying drawings of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0021] Please refer to the attached Figure 1 , the present invention embodiment provides a power-on self-contained dynamic effect decorative light strip structure, including: A current control module for adjusting the magnitude of the current in the light strip to ensure that the current is within a safe operating range; In this embodiment, the current control module dynamically adjusts the current magnitude according to different requirements of the light strip operation through an adaptive current regulation unit. The current regulation unit will adjust the current in real time according to different dynamic effect requirements. For example, when the light strip displays a high brightness or a rapidly changing light effect, the system will increase the current; while when the light strip displays a soft gradient effect, the current will be reduced. The adjustment of the current not only ensures the normal operation of the light strip, but also can save energy by adjusting the power consumption.

[0022] As an option, the current control module further includes a current fluctuation suppression unit for reducing the amplitude of current fluctuations. The working principle of this part is based on the optimization of the control strategy to prevent the current from changing too much due to power supply fluctuations or other external interferences. By implementing this control strategy, the system can keep the current stable and reduce the heat generation and energy efficiency loss caused by current instability.

[0023] Specifically, the current regulation unit includes a real-time current sampling unit, which can monitor the current of each lamp bead in the light strip in real time and transmit the data to the control unit through a feedback mechanism. The control unit adjusts the current output according to the sampled data so that the current value of each lamp bead is within a preset range. The system coordinates and controls the currents of multiple lamp beads to ensure that each part of the light strip can work in the best state.

[0024] In a possible implementation, a Kalman filter is used to process the current data from the current sensor. Since there are often noises or errors in the current signal, the Kalman filter can effectively eliminate these noises and make the current data more accurate. The working principle of the Kalman filter is based on recursive estimation. First, the system state is predicted, and then the prediction result is corrected according to the measured value to obtain a more accurate current value. Its update formula is as follows: Where: is the estimated value of the current at time k (unit: ampere); y(k) is the current value measured by the sensor at time k (unit: ampere); K(k) is the Kalman gain, representing the response sensitivity to the measured value; H is the observation matrix, representing the relationship between the system state and the measured value.

[0025] Through this filtering process, the Kalman filter can effectively improve the accuracy of current control and reduce the errors caused by noise interference.

[0026] Generally, the suppression of current fluctuations is mainly achieved through the PID control (Proportional-Integral-Derivative control) mechanism. The PID controller balances current fluctuations by adjusting the proportional, integral, and derivative parameters. The controller calculates the error of the current in real time and adjusts the current output to reduce fluctuations.

[0027] Current optimization and adaptive adjustment mechanism In addition to the Kalman filter and PID control, this embodiment also adopts a genetic algorithm optimization mechanism. The genetic algorithm optimization unit performs non-linear optimization distribution of current among multiple LED lamp beads to achieve more efficient current utilization. The genetic algorithm conducts a global search based on the power requirements and current fluctuations of the lamp beads to find the optimal current distribution scheme. Its basic process includes operations such as selection, crossover, and mutation. Through these steps, the genetic algorithm can select the most suitable current adjustment strategy among multiple schemes, thus ensuring the efficient operation of the system.

[0028] In the specific implementation process, the objective function of the genetic algorithm can be defined as: Where: f(x) is the objective cost function; P i is the power of the i-th LED lamp bead (unit: watt); is the change rate of the current of the i-th LED lamp bead (unit: ampere / second); R is the weight coefficient of the current change rate, used to control the impact of current fluctuations on power consumption; N is the number of LED lamp beads in the light strip.

[0029] By optimizing this cost function, the genetic algorithm can achieve the optimal distribution of current in the dynamically changing lighting effects, ensuring that the current control of each lamp bead meets the actual requirements.

[0030] Cooperative work of the current control module and other modules The current control module is closely related to the thermal effect management module and the power-on self-start module. The stability of the current directly affects the heat generation of the light strip, which in turn affects the operation of the thermal effect management module. The thermal effect management module ensures that the light strip does not overheat due to excessive current during operation by controlling the temperature. Therefore, the precise control of the current is crucial for the thermal management of the entire system.

[0031] Similarly, the current increase process of the power-on self-start module also needs to cooperate closely with the current control module to ensure that during the startup process, the current increases gradually rather than suddenly, thus avoiding excessive impact on the circuit and affecting the stability of the overall system.

[0032] Specifically, the current control module receives feedback information from the thermal effect management module and the power-on self-start module through the control unit, and adjusts the current output according to the feedback. For example, during the startup process, the current control module will gradually increase the current according to the current increase control strategy without immediately reaching full power, thus avoiding power overload or overheating of the light strip caused by instantaneous current fluctuations.

[0033] The current control module in this embodiment ensures the stable operation of the light strip under various dynamic effects through precise adjustment mechanisms and optimization algorithms. The combined action of the Kalman filter, PID control, and genetic algorithm optimization ensures the minimization of current fluctuations, the control of power consumption, and further improves the overall stability and efficiency of the system through collaborative work with the thermal effect management module and the power-on self-start module.

[0034] The thermal effect management module is used to regulate the heat distribution within the light strip and optimize the heat dissipation design; In this embodiment, the thermal effect management module mainly includes a non-linear heat flow model and a thermal radiation transfer model, which are used to accurately calculate the heat transfer and heat dissipation process within the light strip. Specifically, the thermal effect management module first calculates the heat transfer within the light strip through the non-linear heat flow model and monitors the temperature of the light strip in real time through the heat feedback mechanism. According to these calculation results, the system can automatically adjust the heat dissipation structure of the light strip to ensure that the temperature remains within a reasonable range.

[0035] Generally, during the heat transfer process within the light strip, due to the working characteristics of the lamp beads and the change of the ambient temperature, the heat distribution is not uniform. As an option, in this embodiment, a non-linear heat flow model is used to calculate the heat distribution path within the light strip. Through the accurate calculation of heat conduction, the system can know the heat flow of each part and make corresponding adjustments accordingly. For example, if the heat in a certain area is too high, the system will optimize the heat dissipation design to reduce the temperature of that area. Specifically, the non-linear heat flow model is based on Fourier's law of heat conduction, and heat conducts along the temperature gradient within the object. Its expression is: Wherein: J is the heat flux density, with the unit of watt per square meter (W / m 2 ); k is the thermal conductivity, with the unit of watt per meter·Kelvin (W / m·K); is the temperature gradient, with the unit of Kelvin per meter (K / m); α is the temperature-dependent non-linear coefficient, with the unit of 1 / K2; T is the temperature, with the unit of Kelvin (K); x is the spatial coordinate, with the unit of meter (m).

[0036] In a possible implementation, the thermal effect management module calculates the heat transfer in real time according to the above model and analyzes the temperature conditions of each lamp bead in the light strip. This model is particularly applicable to the situation where the heat flux density changes accordingly when the temperature rises. In some embodiments, in order to improve the accuracy of the system, the module also considers the non-linear relationship between temperature and heat flux, so as to more accurately reflect the dynamic heat changes inside the light strip.

[0037] In addition to heat flux calculation, the thermal effect management module also includes a thermal radiation transfer model for calculating the thermal radiation power generated by the lamp beads of the light strip. According to the Stefan-Boltzmann law, the thermal radiation power is proportional to the fourth power of the temperature. The formula is: P rad = σ∈AT 4 Wherein: P rad is the thermal radiation power, with the unit of watt (W); σ is the Stefan constant, with the unit of 5.67×10 - 8W / m 2 K 4 ; ∈ is the emissivity, representing the heat generation ability of the object, ranging from 0 to 1; A is the surface area of the lamp bead, with the unit of square meter (m 2 ); T is the temperature of the object, with the unit of Kelvin (K).

[0038] Specifically, this model helps calculate the thermal radiation power of each lamp bead, thereby providing a basis for optimizing the heat dissipation structure. In practical applications, the radiation power of the lamp bead increases with the increase of temperature. Therefore, the system needs to adjust the heat dissipation path and materials in a timely manner according to the calculation results to prevent local overheating.

[0039] As an option, the thermal effect management module can also perform simulation analysis on the heat distribution path inside the light strip through finite element analysis (FEA) technology. This technology can help the system identify possible heat accumulation areas during the design phase and take measures in advance. For example, FEA technology can help determine the most suitable heat sink layout for the light strip and the use of heat dissipation materials, thereby improving the overall heat dissipation efficiency.

[0040] In a possible implementation, the FEA simulation system simulates the thermal effects under different working conditions, thereby predicting the heat flow distribution in each area and optimizing the heat dissipation design accordingly. Through this method, the system can adjust the heat dissipation path in real time according to the temperature changes under different working environmental conditions, avoiding a decrease in the performance of the light strip due to excessive temperature.

[0041] Cooperation of Thermal Effect Management with Other Modules The cooperation of the thermal effect management module with the current control module and the power-on self-start module is crucial. The current control module affects the power consumption of the light strip by adjusting the current, thereby affecting the generated heat. If the current is too large, too much heat will be generated, and then the thermal effect management module needs to strengthen heat dissipation. The coordination between the current control module and the thermal effect management module ensures that the system can respond to the temperature changes caused by current fluctuations in real time.

[0042] The power-on self-start module needs to cooperate with the thermal effect management module to ensure that there is no overheating due to a sudden increase in current during the startup phase. Through a smooth current increase process, the system can avoid violent fluctuations in thermal effects during the startup process. The control unit coordinates the work of these three to ensure a smooth transition of current, heat, and the startup process.

[0043] Through the above implementation, the thermal effect management module uses the non-linear heat flow model and the thermal radiation transfer model to calculate and adjust the heat distribution inside the light strip in real time. This design ensures that the light strip can operate at a stable temperature, avoiding a decrease in performance due to overheating. Through cooperation with the current control module and the power-on self-start module, the system can effectively respond to the heat fluctuations caused by current changes and maintain the long-term stable operation of the light strip. By introducing finite element analysis technology (FEA) and other optimization algorithms, the thermal effect management module further improves the accuracy of the heat dissipation design, making thermal management more efficient.

[0044] The power-on self-start module is used to control the light strip to gradually increase the current when powered on, avoiding a sudden increase in current; In this embodiment, the design of the power-on self-start module mainly relies on the Lyapunov stability theory and the fuzzy controller. When powered on, the current increase control unit uses the control strategy designed based on the Lyapunov stability theory to gradually increase the current instead of suddenly increasing it. This control method can avoid equipment damage caused by instantaneous current fluctuations and can also smoothly transition to the normal working state of the system.

[0045] Generally, the working principle of the power-on self-start module is that when the light strip is powered on, the increase process of the current is not instantaneous but slow. This gradually increasing current will not cause a burden on the circuit in the initial stage. As an option, this current increase process follows the control law in the Lyapunov stability theory, causing the current to gradually increase when powered on and reach the target current within a preset time.

[0046] Specifically, the Lyapunov stability theory analyzes the stability of the system by constructing a Lyapunov function. The design of the Lyapunov function is usually achieved through the following steps: V(x(t))=x(t) T Px(t) Where: x(t) is the state vector of the current; P is a positive definite matrix used to ensure the stability of the system.

[0047] By adjusting the matrix P, the control system can ensure a smooth increase in the current when powered on and will not cause an impact on the power supply or the light strip circuit. The derivative of the Lyapunov function Must be negative to ensure that the system converges to the stable state at each time point.

[0048] In a possible implementation, the power-on self-start module calculates the current increase rate and combines the Lyapunov stability theory to control every detail in the current increase process and avoid sudden increases in the current. In practical applications, the control unit will adjust the increase rate according to the system feedback, thereby ensuring that each startup can be completed smoothly and avoiding unnecessary electrical faults caused by current fluctuations.

[0049] The role of the fuzzy controller As an option, the fuzzy controller is used to finely adjust the rate of current increase. The fuzzy controller adjusts the current increase rate in real time based on the real-time data of the current and temperature. Through fuzzy control rules, the system can cope with the uncertainty and complexity of current changes. Specifically, the fuzzy controller will determine the adjustment step size according to the difference between the current current and the target current. This method can make the current increase process smoother and avoid overloading the circuit due to too fast current changes.

[0050] Specifically, the fuzzy controller describes the process of increasing current by setting a number of rules. For example, when the difference between the current and the target value is large, the controller may increase the step size of the increase; when the current approaches the target value, the step size is reduced, thus smoothing the current change.

[0051] The working formula of the fuzzy controller can be expressed as: Where: u(t) is the control signal, representing the adjustment amount of the current; w i is the weight of the fuzzy rule, reflecting the influence degree of each rule; μ i (x(t)) is the fuzzy membership function, representing the membership degree of the current state x(t) to the i-th rule.

[0052] In the fuzzy controller, the rate of current change is determined by the membership function, and the output control signal is adjusted in real time according to the deviation between the actually measured current and the target current, ensuring that the current increases gradually and avoiding sudden increases.

[0053] Cooperation with other modules The power-on self-start module not only needs to independently control the process of increasing current, but also needs to cooperate with other modules. Especially in cooperation with the current control module and the thermal effect management module, it ensures that the current will not be unstable due to excessive load changes during the startup process. The current control module monitors the current in real time and ensures the accuracy of current control through a Kalman filter. If the current increases too fast, the current control module will adjust the current output according to the feedback information to avoid unnecessary system load caused by excessive current.

[0054] At the same time, the thermal effect management module will adjust the heat dissipation design according to the current change. During the process of increasing current, if the temperature rises, the thermal effect management module will adjust the heat dissipation strategy to ensure that the system will not overheat due to sudden current increase and affect the normal operation of the light strip. The synergistic effect of the two enables the power-on self-start module to make a smooth transition during the startup process, not only avoiding current surges, but also optimizing the overall system thermal management.

[0055] Through the above implementation method, the power-on self-start module realizes the smooth increase of current by combining the Lyapunov stability theory and the fuzzy controller, ensuring that the system will not be impacted by sudden current at the moment of power-on. This module works in cooperation with the current control module and the thermal effect management module, and can accurately adjust the process of increasing current during startup to avoid negative impacts on the circuit caused by current fluctuations. Through these innovations, the startup process of the system is smoother, the operation is more stable, and the reliability and service life of the light strip are further improved.

[0056] A control unit for coordinating the operation of the current control module, the thermal effect management module, and the power-on self-start module to ensure the stable operation of the light strip; In this embodiment, the control unit receives feedback signals from the current control module, the thermal effect management module, and the power-on self-start module, processes and analyzes these signals, and finally outputs corresponding adjustment instructions. Specifically, the control unit can coordinate each module based on real-time data, thereby optimizing the operating state of the light strip and avoiding excessive current fluctuations, overheating, or instability during startup.

[0057] Generally, the control unit realizes its coordination function through the following aspects: Receiving current signals and power consumption data from the current control module, adjusting the current output to ensure that the current is within the preset safe range; Receiving temperature data from the thermal effect management module, judging whether the current working environment exceeds the preset temperature range, and timely adjusting the heat dissipation strategy; Receiving the progress information of the increasing current from the power-on self-start module to ensure a smooth current increase process without causing too much impact on the system.

[0058] As an option, the processing mechanism of the control unit makes dynamic decisions based on real-time collected data. These data include current magnitude, temperature change, startup status, etc. The control unit analyzes and calculates the adjustment parameters most suitable for the current working state through algorithms. For example, during the startup stage of the light strip, the control unit will coordinate the current increase progress of the power-on self-start module while monitoring the temperature change to ensure that the temperature does not cause the system to overheat due to sudden current increase.

[0059] Specifically, the control unit first processes the data from the current control module to judge whether the current current meets the preset working range. If the current exceeds the set range, the control unit will send an adjustment signal to the current control module to reduce current fluctuations. The control unit will also ensure the rationality of current adjustment by calculating the power consumption in real time.

[0060] In a possible implementation, the control unit combines the PID control algorithm and the fuzzy control strategy to optimize the adjustment process of current and temperature. The PID controller optimizes current adjustment by adjusting the proportional, integral, and derivative parameters. For complex non-linear situations, the control unit can make decisions through the fuzzy control algorithm to adjust the current increase rate or the working mode of the heat dissipation system in real time. The working formula of the fuzzy controller is as follows: Where: u(t) is the control signal, representing the adjustment amount of current or temperature; w iis the weight of the fuzzy rule, reflecting the influence of each rule; μ i (x(t)) is the fuzzy membership function, representing the relationship between the control signal and the current state.

[0061] The control unit dynamically adjusts parameters such as current and temperature according to these rules to ensure that the system always maintains the best working state.

[0062] In some embodiments, the control unit can also adopt an adaptive control method based on neural networks. By training the neural network model, the system can more accurately predict the change trends of parameters such as current and temperature and make corresponding adjustments in advance. This method can further improve the adaptive ability and response speed of the system.

[0063] The collaborative work of the control unit and other modules The close cooperation between the control unit and the current control module, the thermal effect management module, and the power-on self-start module ensures the stability and efficiency of the system. The current control module is responsible for real-time adjusting the current and transmitting the current data to the control unit. The control unit judges whether the current reaches the preset target according to the current data and sends an adjustment signal to the current control module.

[0064] The thermal effect management module monitors the temperature and transmits the real-time data to the control unit. The control unit adjusts the heat dissipation strategy according to the temperature data. The power-on self-start module controls the gradual increase of the current and feeds back the progress of the current increase to the control unit. After receiving the data from the power-on self-start module, the control unit adjusts the current increase rate according to the actual situation to ensure a smooth increase of the current.

[0065] Specifically, the control unit issues adjustment instructions to the current control module according to the real-time data of current fluctuations and temperature changes. When the current fluctuates greatly, the control unit adjusts the current adjustment rate to avoid the impact of violent current fluctuations on the system; when the temperature is too high, the control unit activates the thermal effect management module to start a more efficient heat dissipation strategy. Through this collaborative effect, the system can start smoothly and operate stably, avoiding damage to the system caused by overcurrent or overheating.

[0066] Through the above implementation methods, the control unit plays a core role in the system. It coordinates the work of the current control module, the thermal effect management module, and the power-on self-start module. The control unit realizes the dynamic adjustment of important parameters such as current and temperature through the analysis and processing of real-time data. The close cooperation between the control unit and other modules ensures the efficient and stable operation of the entire LED strip system. This design not only improves the overall performance of the system but also enables the LED strip to cope with various dynamic effects and changes in the working environment, ensuring the long-term stability and service life of the LED strip.

[0067] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
