[0068] When LED light control circuit 10 switches to music rhythm mode, the 5V power supply provides a voltage to microphone MIC1 through resistor R13. Filter capacitor C14 is used to filter out environmental interference from the microphone signal, and coupling capacitor C13 is used to limit the bandwidth of the microphone signal and remove noise interference, thereby improving signal quality and clarity.
[0069] When music or sound is played, it changes the resistance of microphone MIC1. When the resistance of microphone MIC1 increases, the voltage received by microphone MIC1 increases. When the resistance of microphone MIC1 decreases, the voltage received by microphone MIC1 decreases. The microphone signal output by microphone MIC1 passes through capacitor C13 and is then coupled to the base of the first transistor Q4. Because the music rhythm module is equipped with resistor R11, the collector of the first transistor Q4 is always in a high-level state. When the microphone signal coupled to the base of the first transistor Q4 is at a high level, the collector and emitter of the first transistor Q4 are turned on, thereby connecting the collector of the first transistor Q4 to ground. Consequently, the collector of the first transistor Q4 is pulled from a high level to a low level.
[0070] When the signal coupled to the base of the first transistor Q4 is low, the collector and emitter of the first transistor Q4 are cut off, and the collector of the first transistor Q4 is high. Therefore, microphone MIC1 can convert music or sound into a microphone signal. The first transistor Q4 converts this microphone signal into a ripple signal, a continuous signal that fluctuates in level with the music. This ripple signal is output from the collector of the first transistor Q4, coupled through capacitor C12, and input into the base of Q3.
[0071] When the signal coupled to the base of the second transistor Q3 is high, the emitter and collector of the second transistor Q3 are cut off, and the music rhythm module 15 outputs no signal. When the signal coupled to the base of the second transistor Q3 is low, the emitter and collector of the second transistor Q3 are turned on. The second transistor Q3 converts the ripple signal into a sound signal, and the music rhythm module 15 can output the sound signal. Furthermore, the first voltage divider resistor R15 and the second voltage divider resistor R16 can divide the sound signal.
[0072] Ultimately, the sound signal flows into the second control chip U3, which collects and processes it through an algorithmic analysis process. Once the algorithm arrives at the result, the second control chip U3 outputs corresponding pulses, thereby controlling the RGB lamp beads 161 of the ambient light to produce a rhythmic effect in response to the music. Furthermore, the user can adjust the resistance values of the first and second voltage-dividing resistors R15 and R16, thereby varying the voltage divider of the sound signal and adjusting the sensitivity to the musical rhythm.
[0073] The operating principle of the present invention is as follows: When the LED light control circuit 10 is in operation, the touch control module 11 can first output a touch data signal via the touch data output pin TK1 / PWM4 / IO4, and the touch control module 11 can output a clock signal via the clock output pin TK2 / IO5. The control module 13 then receives the touch data signal via the touch data input pin IO2 / PWM2 / AN0 and the clock signal via the clock input pin IO9 / AN6. The control module 13 can pulse-width modulate the touch data signal and the clock signal, thereby generating a white light signal and a warm light signal. Alternatively, the infrared sensor module 12 can output an infrared sensing signal via the IR pin, and the touch module 11 can output a clock signal via the clock output pin TK2 / IO5. The control module 13 then receives the infrared sensing signal via the infrared sensor input pin IO13 / AN9 and the clock signal via the clock input pin IO9 / AN6. The control module 13 can pulse-width modulate the infrared sensing signal and the clock signal, thereby generating a white light signal and a warm light signal. Then, the control module 13 may output a white light signal through the first PWM output pin PA2 / AIN2 / NRST / PWM0 , and the control module 13 may output a warm light signal through the second PWM output pin PA4 / AIN3 / PWM1 .
[0074] Subsequently, the light board module 14 may receive the white light signal and the warm light signal, which are used to control the on / off of the LED light inside the light board module 14. Alternatively, the white light signal and the warm light signal may adjust the brightness of the LED light inside the light board module 14. Alternatively, the white light signal and the warm light signal may adjust the color temperature of the LED light inside the light board module 14.
[0075] When LED light control circuit 10 switches to music rhythm mode, the 5V power supply provides a voltage to microphone MIC1 through resistor R13. Filter capacitor C14 is used to filter out environmental interference from the microphone signal, and coupling capacitor C13 is used to limit the bandwidth of the microphone signal and remove noise interference, thereby improving signal quality and clarity.
[0076] When music or sound is played, it changes the resistance of microphone MIC1. When the resistance of microphone MIC1 increases, the voltage received by microphone MIC1 increases. When the resistance of microphone MIC1 decreases, the voltage received by microphone MIC1 decreases. The microphone signal output by microphone MIC1 passes through capacitor C13 and is then coupled to the base of the first transistor Q4. Because the music rhythm module is equipped with resistor R11, the collector of the first transistor Q4 is always in a high-level state. When the microphone signal coupled to the base of the first transistor Q4 is at a high level, the collector and emitter of the first transistor Q4 are turned on, thereby connecting the collector of the first transistor Q4 to ground. Consequently, the collector of the first transistor Q4 is pulled from a high level to a low level.
[0077] When the signal coupled to the base of the first transistor Q4 is low, the collector and emitter of the first transistor Q4 are cut off, and the collector of the first transistor Q4 is high. Therefore, microphone MIC1 can convert music or sound into a microphone signal. The first transistor Q4 converts this microphone signal into a ripple signal, a continuous signal that fluctuates in level with the music. This ripple signal is output from the collector of the first transistor Q4, coupled through capacitor C12, and input into the base of Q3.
[0078] When the signal coupled to the base of the second transistor Q3 is high, the emitter and collector of the second transistor Q3 are cut off, and the music rhythm module 15 outputs no signal. When the signal coupled to the base of the second transistor Q3 is low, the emitter and collector of the second transistor Q3 are turned on. The second transistor Q3 converts the ripple signal into a sound signal, and the music rhythm module 15 can output the sound signal. Furthermore, the first voltage divider resistor R15 and the second voltage divider resistor R16 can divide the sound signal.
[0079] Ultimately, the sound signal flows into the second control chip U3, which collects and processes it through an algorithmic analysis process. Once the algorithm arrives at the result, the second control chip U3 outputs corresponding pulses, thereby controlling the RGB lamp beads 161 of the ambient light to produce a rhythmic effect in response to the music. Furthermore, the user can adjust the resistance values of the first and second voltage-dividing resistors R15 and R16, thereby varying the voltage divider of the sound signal and adjusting the sensitivity to the musical rhythm.
[0080] The utility model provides an LED lamp control circuit, which is provided with a control module. The control module can control the switching of an LED lamp inside a light board module based on a white light signal and a warm light signal, or can adjust the brightness of the LED lamp inside the light board module based on the white light signal and the warm light signal, or can adjust the color temperature of the LED lamp inside the light board module based on the white light signal and the warm light signal.
[0081] This LED light control circuit is equipped with a music rhythm module and an ambient light module. The music rhythm module outputs a sound signal. The control module performs pulse width modulation on the sound signal, thereby generating a control signal. The ambient light module receives the control signal, which is used to adjust the different modes of the RGB lamp beads within the ambient light module. Therefore, an LED clip light equipped with this LED light control circuit not only provides dual-color temperature LED lighting but also adds the function of ambient lighting with RGB lamp beads. This effectively solves the technical problem of existing clip lights being relatively limited in functionality. This LED clip light equipped with this LED light control circuit can create an overall sense of ambiance in the illuminated space, allowing users to use it in a variety of daily life scenarios, effectively enriching their daily needs and providing a good user experience. This LED clip light equipped with this LED light control circuit can meet users' lighting and ambiance needs, eliminating the need to purchase separate RGB lamp beads, saving space and reducing the cost of purchasing the lighting fixture.
