Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
The following describes a dimming and toning system based on pulse phase control according to an embodiment of the present application with reference to fig. 1.
As shown in fig. 1, the dimming and color-mixing system based on pulse phase control according to the embodiment of the present application includes an LED lamp set module 100, a main control module 200, a dimming module 300, a color temperature mixing module 400, and a driving module 500.
The LED lamp group module 100 includes a first LED lamp group 110 and a second LED lamp group 120; the first LED lamp group 110 and the second LED lamp group 120 have different color temperature values; the main control module 200 is used for controlling the input of alternating current; the dimming module 300 is connected to the main control module 200, and is configured to perform phase-cut control according to the ac input to output a dimming control signal; the color temperature adjusting module 400 is connected to the main control module 200, and is configured to output a single pulse control signal in the chopping phase-cut region in a preset time period according to the fact that the working state of the dimming module 300 is the chopping phase-cut state, and also configured to send a control instruction to the dimming module 300 according to the fact that the working state of the dimming module 300 is not the chopping phase-cut state, so that the working state of the dimming module 300 is in the preset chopping phase-cut state, and output the single pulse control signal in the chopping phase-cut region; the driving module 500 is connected to the dimming module 300 and the color temperature adjusting module 400, and is configured to receive and adjust the duty ratio signals output by the two paths according to the dimming control signal and the single pulse control signal, so as to adjust the color temperature and the brightness of the LED lamp set module 100.
The color temperature adjusting module 400 outputs a single pulse control signal after performing different processes according to the operating state of the light adjusting module 300. When the dimming module 300 works in the chopping and phase-cutting state, the color temperature adjusting module 400 sends a single-pulse control signal in the chopping and phase-cutting region according to a preset time period, and the driving module 500 adjusts the color temperature of the LED lamp group module 100 after receiving the single-pulse control signal. When the dimming module 300 is not in the chopping phase-cut state, the color temperature adjusting module 400 sends a control instruction to the dimming module 300, so that the dimming module 300 works in the preset chopping phase-cut state, and outputs a single pulse control signal to control the color temperature of the LED lamp group module 100. For example, if the preset chopping phase-cut state is the minimum allowable chopping phase-cut state, the dimming module 300 operates in the minimum allowable chopping phase-cut state after receiving the control instruction, and at this time, the color temperature adjusting module 400 outputs a single pulse control signal, so that the driving module 500 adjusts the color temperature of the LED lamp group module 100. Presetting the chopping phase-cut state can ensure that a chopping phase-cut region exists all the time to allow the color temperature adjusting module 400 to send a single pulse control signal, so as to realize that the LED lamp group module 100 simultaneously performs color adjusting and dimming operations.
According to the dimming and color mixing system based on pulse phase control, the single-pulse control signal is output by the color temperature mixing module according to the working state of the dimming module, the color temperature of the LED lamp bank module is modulated by the driving module according to the single-pulse control signal, and the color temperature can be modulated while the brightness of the LED lamp bank module is modulated. Meanwhile, a complex control system is not required to be added, the brightness and the color temperature of the LED lamp group module can be modulated under the condition of original circuit wiring, and the wiring difficulty and the hardware cost are reduced.
In some embodiments of the present application, as shown in fig. 1 and fig. 2, the color temperature adjusting module 400 includes a color temperature adjusting submodule 410 and an encoding submodule 420, where the color temperature adjusting submodule 410 is configured to output a color temperature adjusting control signal when the operating state of the dimming module 300 is the chopping phase-cut state, and output the color temperature adjusting control signal and send a control instruction to the dimming module 300 when the operating state of the dimming module 300 is the preset chopping phase-cut state; the encoding submodule 420 is connected to the color temperature adjusting submodule 410, and is configured to receive the color temperature adjusting control signal and encode the color temperature adjusting control signal in the chopping phase-cut region to output a single pulse control signal.
For example, the encoding sub-module 420 is connected to the color temperature adjusting sub-module 410, the color temperature adjusting sub-module 410 outputs a color temperature adjusting control signal according to the operating state of the light adjusting module 300, outputs the color temperature adjusting control signal when the operating state of the light adjusting module 300 is the chopping phase-cut state, outputs the color temperature adjusting control signal and sends a control command to the light adjusting module 300 when the operating state is the preset chopping phase-cut state, and the light adjusting module 300 operates in the minimum allowable chopping phase-cut state after receiving the control command. The coding sub-module 420 receives the color temperature control signal and codes the color temperature control signal to obtain a single pulse control signal, and sends the single pulse control signal to the driving module 500, thereby realizing the adjustment of the color temperature of the LED lamp set module 100. After receiving the color temperature adjustment control signal, the encoding submodule 420 encodes the single pulse signal according to a preset encoding rule to obtain a single pulse control signal. The driving module 500 decodes the single pulse control signal after receiving the single pulse control signal, so as to determine the duty ratios of the two paths of outputs of the LED lamp group module 100. The color temperature of the LED lamp set module 100 is controlled by adjusting the duty ratios of the two outputs.
In some embodiments of the present application, as shown in fig. 1 and 3, the driving module 500 includes a dimming driving sub-module 510, a color temperature driving sub-module 520, a driving sub-module 530, and a decoding module 540, the dimming driving sub-module 510 is configured to receive and generate a dimming driving signal according to a dimming control signal; the color temperature adjusting driving submodule 520 is used for receiving and generating a color temperature adjusting driving signal according to the single pulse control signal; the decoding module 540 is configured to receive and adjust duty ratios of the two output PWM signals according to the dimming driving signal and the color temperature modulation driving signal, and according to the dimming driving signal and the decoded color temperature modulation driving signal; the driving sub-module 530 is used for receiving and outputting a driving signal to the LED lamp group module 100 according to the PWM signal.
For example, the dimming module 300 performs phase-cut control on the ac input and generates a dimming control signal. The dimming driving sub-module 510 receives and generates a dimming driving signal according to the dimming control signal. After receiving the dimming driving signal, the decoding module 540 adjusts the duty ratio according to the information carried by the dimming driving signal, thereby outputting a PWM signal. The driving sub-module 530 outputs a driving signal according to the PWM signal, and controls the current and the frequency of the LED lamp set module 100, so as to adjust the brightness of the LED lamp set module 100.
The color temperature adjusting module 400 outputs a single pulse control signal in the chopping and phase-cutting region, and the color temperature adjusting submodule 410 receives and generates a color temperature adjusting driving signal according to the single pulse control signal.

The driving submodule 530 outputs corresponding driving signals to the LED lamp set module 100 according to the two PWM signals, and can change the current and frequency passing through the first LED lamp set 110 and the second LED lamp set 120 by adjusting the two output duty ratios, thereby adjusting the color temperature of the LED lamp set module 100.
In some embodiments of the present application, as shown in fig. 1 and 4, the PWM signal includes a first PWM signal and a second PWM signal, the driving sub-module 530 includes a first driving unit 531 and a second driving unit 532, the first driving unit 531 is configured to receive the first PWM signal and output the first driving signal to the first LED lamp group 110 according to the first PWM signal, and the second driving unit 532 is configured to receive the second PWM signal and output the second driving signal to the second LED lamp group 120 according to the second PWM signal.

Similarly, the second LED lamp set 120 receives a second driving signal sent by the second driving unit 532. Under the control of the first and second driving units 531 and 532, the brightness and color temperature of the LED lamp set module 100 can be adjusted by changing the current of the first and second LED lamp sets 110 and 120.

The protection module 600 can protect the normal operation of the dimming and color-adjusting system based on pulse phase control, and detect the changes of phase, temperature and current in the phase-cutting process.
