[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-3 An intelligent Bluetooth music light control system of this embodiment includes:

[0045] a sound unit, at least one group of light-emitting units, at least one group of auxiliary light units, an ambient light sensor, a human body sensing unit, and a control unit, Figure 1 The Bluetooth music lamp has a sound unit, a group of light units and a group of auxiliary light units. Figure 2 The Bluetooth music lamp has a sound unit, two sets of light units and two sets of auxiliary light units;

[0046] The control unit adjusts the flashing frequency and color change of the light-emitting unit and the auxiliary light unit in real time by analyzing the rhythm and frequency of the music signal emitted by the sound-emitting unit, so that the lighting effect is synchronized with the music rhythm;

[0047] The control unit also detects the ambient light intensity through the ambient light sensor, and automatically adjusts the brightness of the light emitting unit and the auxiliary light unit according to the detected ambient light intensity;

[0048] The control unit also detects the position of the user in the space through an ultrasonic or infrared sensor, and dynamically adjusts the irradiation direction and range of the light emitting unit and the auxiliary light unit according to the detected user position;

[0049] The control unit also dynamically adjusts the irradiation direction and range of the light emitting unit and the auxiliary light unit in combination with the music rhythm and the user's position, so that the light changes along with the user's movement trajectory.

[0050] The smart Bluetooth music light control system provided by the present invention is an intelligent device that integrates music playback, light control and environmental perception. The system can receive and play music from smart phones or other Bluetooth devices via Bluetooth connection, and adjust the flashing frequency and color changes of the lights in real time according to the rhythm and frequency of the music, creating a lighting effect synchronized with the music. In addition, the system also has ambient light detection and human body sensing functions, and can automatically adjust the brightness and illumination direction of the lights according to the ambient light intensity and user position, providing a more comfortable and immersive use experience.

[0051] Among them, by introducing advanced music signal processing algorithms, the system can accurately detect the intensity and frequency of the music rhythm, thereby achieving a high degree of synchronization between the lighting effects and the music rhythm; by introducing multiple light sensors, the system can comprehensively detect changes in ambient light intensity, thereby achieving precise adjustment of light brightness; by introducing ultrasonic or infrared sensors, the system can accurately detect changes in the user's position in three-dimensional space, thereby achieving dynamic adjustment of the direction and range of light illumination; by combining music rhythm, ambient light intensity and user position, the system can achieve multi-dimensional dynamic adjustment of light flashing frequency, color changes, brightness and illumination direction, thereby creating richer and more immersive lighting effects.

[0052] It should be noted that the ambient light sensor includes a plurality of photosensitive elements, and the photosensitive elements are used to detect the intensity of ambient light.

[0053] Furthermore, the control unit detects the intensity of the music rhythm by the following algorithm:

[0054]

[0055] Where R(t) represents the intensity of the music rhythm at time t, A(τ) is the amplitude of the music signal, and T is the time window;

[0056] The algorithm quantifies the intensity of music rhythm by calculating the average absolute value of the amplitude of the music signal within the time window T. When the music rhythm is strong, the amplitude changes greatly and the R(t) value is high; when the music rhythm is gentle, the amplitude changes less and the R(t) value is low. In addition, the choice of time window T affects the sensitivity of rhythm detection. A shorter T can capture rapid rhythm changes, while a longer T is more suitable for detecting the overall rhythm trend.

[0057] The control unit adjusts the flashing frequency of the light emitting unit and the auxiliary light unit according to the detected music rhythm intensity:

[0058] F(t)=k·R(t)

[0059] Where F(t) is the light flickering frequency at time t, and k is the proportionality coefficient;

[0060] The light flickering frequency F(t) is proportional to the music rhythm intensity R(t). The proportional coefficient k determines the range of light flickering frequency. When the music rhythm is strong, the R(t) value is high, the light flickering frequency F(t) will increase accordingly, and the lighting effect will be more dynamic and active. When the music rhythm is slow, the R(t) value is low, the light flickering frequency F(t) will decrease, and the lighting effect will be softer and more soothing.

[0061] It should be noted that the system receives audio signals from smartphones or other devices via Bluetooth, decodes them, extracts audio data, and samples the audio signals in real time to obtain the amplitude A(τ) at each time point. Based on the sampled data, the system calculates the average absolute value of the amplitude R(t) within the current time window T.

[0062] At the same time, the system controls the brightness and flashing frequency of the LED lights through PWM (pulse width modulation) technology. According to the calculated flashing frequency F(t) of the light, the system dynamically adjusts the flashing frequency of the LED lights to synchronize it with the rhythm of the music. In addition to the flashing frequency, the system can also adjust the color changes of the lights according to the intensity of the music rhythm, such as using brighter colors when the rhythm is strong and softer colors when the rhythm is slow.

[0063] Furthermore, the control unit detects the ambient light intensity by the following algorithm:

[0064]

[0065] Where E(t) is the ambient light intensity at time t, L i (t) is the reading of the ith light sensor, and N is the number of light sensors;

[0066] The algorithm quantifies the ambient light intensity by calculating the average value of multiple light sensor readings. Using multiple light sensors can improve the accuracy and robustness of ambient light detection and avoid the impact of single sensor reading errors on the overall result. The ambient light intensity E(t) at time t reflects the current ambient light and provides a basis for subsequent light brightness adjustments.

[0067] The control unit adjusts the brightness of the light emitting unit and the auxiliary light unit according to the detected ambient light intensity:

[0068]

[0069] Among them, B(t) is the light brightness at time t, B max is the maximum brightness of the light, E max is the maximum intensity of ambient light;

[0070] The light brightness B(t) is inversely proportional to the ambient light intensity E(t). When the ambient light intensity is high, the light brightness is low; when the ambient light intensity is low, the light brightness is high. In this way, the system can automatically adjust the light brightness to ensure comfortable lighting effects under different lighting conditions.

[0071] Furthermore, the control unit detects the user position by the following algorithm:

[0072] P(t) = (x(t), y(t), z(t)) where P(t) is the 3D coordinate of the user at time t;

[0073] User location detection is usually achieved through infrared sensors, ultrasonic sensors, cameras or Bluetooth signal strength (RSSI). The system collects user location data in real time and obtains the user's precise location in three-dimensional space through coordinate conversion and filtering algorithms. The user's location P(t) at time t provides a basis for subsequent light direction adjustment.

[0074] The control unit adjusts the irradiation direction of the light emitting unit and the auxiliary light unit according to the detected user position:

[0075]

[0076] Among them, θ(t) is the horizontal angle of the light;

[0077] The light direction angle θ(t) is determined by calculating the horizontal angle between the user and the lamp. The system dynamically adjusts the horizontal angle of the light according to the user's position to ensure that the light always shines on the user's position. If the vertical angle (pitch angle) needs to be adjusted, a similar algorithm can be used to calculate the vertical angle.

[0078] Further, the sound-generating unit is used to play music signals, the light-emitting unit is used to provide a main light source, and the auxiliary light unit is used to provide an auxiliary light source;

[0079] The ambient light sensor is used to detect the ambient light intensity, and the human body sensing unit is used to detect the position of the user in the space;

[0080] The control unit is used to adjust the flashing frequency, color change, brightness, illumination direction and range of the light-emitting unit and the auxiliary light unit in real time according to the rhythm and frequency of the music signal, the ambient light intensity and the user's position, so as to achieve synchronization of lighting effects with the music rhythm, adaptive adjustment of ambient light and dynamic lighting tracking.

[0081] Suppose the user is playing a piece of electronic music with a strong rhythm through the Bluetooth music light:

[0082] When the system detects that the music rhythm intensity R(t) is high, it adjusts the light flashing frequency F(t) to a higher value, causing the light to flash quickly and adjusts the light color to bright red and blue, alternating between them. If the ambient light is dim, the system automatically increases the light brightness to ensure that the lighting effect is obvious. If the user moves to the other side of the room, the system dynamically adjusts the light's direction so that the light always follows the user.

[0083] Assume that the user uses a Bluetooth music lamp in a dimly lit room:

[0084] When the system detects that the ambient light intensity E(t) is low, it adjusts the light brightness B(t) to a higher value to provide sufficient lighting. Users can view the current light brightness through the mobile phone APP and manually adjust the brightness or switch scene modes as needed. If the ambient light intensity changes (for example, the curtains are opened), the system will automatically adjust the light brightness to ensure that the lighting effect is always comfortable.

[0085] Assume that a user uses a Bluetooth music light in a room:

[0086] The system detects the user's three-dimensional coordinates P(t), calculates the horizontal angle θ(t) of the light, and adjusts the direction of the light. The user can view the current direction of the light through the mobile phone APP and manually adjust the direction or switch scene modes as needed. If the user's position changes (for example, the user moves to the other side of the room), the system will automatically adjust the direction of the light to ensure that the light always shines on the user's location.

[0087] Furthermore, the human body sensing unit is an ultrasonic or infrared sensor, and the ultrasonic or infrared sensor includes a plurality of ultrasonic or infrared transmitters and receivers, and the transmitters and receivers are used to detect the position of the user in space.

[0088] Furthermore, the sound-generating unit includes a speaker and an audio processing module, and the audio processing module is used to analyze the rhythm and frequency of the music signal.

[0089] Furthermore, the light-emitting unit includes an LED light group and a driving circuit, and the driving circuit is used to control the flashing frequency and color change of the LED light group.

[0090] Furthermore, the auxiliary light unit includes an LED light group with adjustable brightness and a driving circuit, and the driving circuit is used to control the brightness and illumination range of the LED light group.

[0091] Furthermore, the control unit includes a microprocessor, a storage module and a wireless communication module, wherein the storage module is used to store algorithms and control programs, and the wireless communication module is used to exchange data with external devices;

[0092] Optionally, the control unit further includes a power management module, and the power management module is used to manage the power supply of the system.
