[0068] In order to make the personnel in the technical field better understand the present application scheme, the technical scheme in the embodiment of the present application will be described clearly and completely below by combining the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all. Based on the embodiment in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0069] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0070] In order to facilitate the understanding of the technical scheme of the present application, the hardware architecture based on the embodiment of the present application is described first.

[0071] Figure 1 is a structure schematic diagram of a compatible thyristor and wireless dimming driving circuit provided by the embodiment of the present application. Figure 1 a is a structure schematic diagram of a thyristor lamp control system provided by the embodiment of the present application. Figure 1 aAn example of a drive circuit 100 compatible with silicon controlled and wireless dimming is shown in the case of being arranged in an LED lamp. Figure 1 a An example of a silicon controlled lamp control system includes a power supply, such as an alternating current power supply Vac, a silicon controlled dimmer 110 connected in series between the positive pole L and the negative pole N of the power supply of the LED lamp.

[0072] In combination Figure 1 and Figure 1 a The drive circuit 100 compatible with silicon controlled and wireless dimming provided by the embodiments of the present application includes: an angle detection module 120 connected with the silicon controlled dimmer 110, the angle detection module 120 is used to obtain the conduction angle data of the silicon controlled dimmer 110; a wireless control module 140 connected with the angle detection module 120, the wireless control module 140 is used to generate a control signal in response to a gesture operation adjustment instruction according to the conduction angle data of the silicon controlled dimmer 110; a power supply adjustment module 130 connected with the silicon controlled dimmer 110 and the wireless control module 140, the power supply adjustment module 130 is used to obtain the power signal transmitted by the silicon controlled dimmer 110, and generate a driving signal according to the control signal.

[0073] Specifically, the angle detection module 120 is connected with the silicon controlled dimmer, and the angle detection module 120 is used to detect the conduction angle data of the silicon controlled dimmer 110, such as the current conduction angle, the historical conduction angle, etc. of the silicon controlled dimmer 110. The angle detection module 120 sends the obtained conduction angle data of the silicon controlled dimmer 110 to the wireless control module 140. The wireless control module 140 receives the conduction angle data. The wireless control module 140 can generate a control signal in response to a gesture operation adjustment instruction and according to the conduction angle data. The control signal can include a PWM control signal or a pulse signal, etc. The wireless control module 140 is connected with the power supply adjustment module 130. The wireless control module 140 sends the control signal to the power supply adjustment module 130. The power supply adjustment module 130 is connected with the silicon controlled dimmer 110. The power supply adjustment module 130 adjusts the output driving signal according to the power signal output by the silicon controlled dimmer 110 and the received control signal. The greater the driving signal, the higher the brightness of the lamp bead connected with the power supply adjustment module.

[0074] In this way, the lightness of the lamp beads can be adjusted by gesture operation on the mobile terminal in the circuit with the triac dimmer 110, which is compatible with the wireless dimming module. The mobile terminal can include a mobile phone, a tablet computer, a wearable device, a remote controller or the like. Since the gesture operation of the target user on the mobile terminal is responsive to the demand of the target user, the wireless control module 140 also receives the conduction angle data of the triac dimmer 110 and generates a control signal according to the conduction angle data, so that the control signal is compatible with the conduction angle data of the triac dimmer 110 and also compatible with the dimming demand of the target user, realizing the function of compatible triac and wireless dimming, improving the dimming effect and meeting the dimming depth needs of the target user.

[0075] It should be noted that, Figure 1 It should be noted that,

[0076] The technical scheme of the embodiment of the present application acquires the conduction angle data of the triac dimmer 110 by setting the angle detection module 120. The wireless control module 140 is connected with the angle detection module 120, and generates a control signal according to the conduction angle data of the triac dimmer 110 in response to the gesture operation adjustment instruction. The power supply adjustment module 130 acquires the power signal transmitted by the triac dimmer 110, and generates a driving signal according to the control signal. In this way, the driving signal is compatible with the conduction angle data of the triac dimmer 110 and also compatible with the dimming demand of the target user, realizing the function of compatible triac and wireless dimming, improving the dimming effect and meeting the dimming depth needs of the target user.

[0077] Optionally, Figure 2 is a schematic diagram of the correspondence between the conduction angle of the triac dimmer and the duty cycle of the control signal provided by the embodiment of the present application. Figure 2a is a schematic diagram of the angle detection module detecting the conduction angle data of the triac dimmer provided by the embodiment of the present application. On the basis of the above embodiment, Figures 1 to 2a The conduction angle data includes a first preset angle and a second preset angle. The wireless control module is also used for matching the first preset angle of the conduction angle data with the first duty cycle of the control signal and matching the second preset angle of the conduction angle data with the second duty cycle of the control signal. The first preset angle is smaller than the second preset angle, and the first duty cycle of the control signal is smaller than the second duty cycle. The range of the duty cycle of the control signal is between the first duty cycle and the second duty cycle. The first preset angle is the conduction angle corresponding to the adjustment of the triac lamp to be extinguished.

[0078] Specifically, referring to Figure 2aThe angle detection module 120 can generate the conduction angle data corresponding to the power supply signal by collecting the phase angle of the power supply signal flowing through the triac dimmer. The conduction angle data output by the angle detection module 120 is a pulse width signal. The wireless control module 140 obtains the AC zero-crossing point and the conduction angle information by detecting the proportion of the conduction time width Ton and the non-conduction time Toff in a cycle or the rising edge and the falling edge in a cycle of the pulse width signal after receiving the conduction angle data.

[0079] The first preset angle and the second preset angle are the minimum conduction angle and the maximum conduction angle of the triac dimmer respectively. It should be noted that the first preset angle is the maximum conduction angle corresponding to the triac lamp being turned off. As shown in Figure 2 The conduction angle of the triac dimmer has a corresponding relationship with the output PWM duty cycle. The duty cycle corresponding to the first preset angle is called the first duty cycle, and the duty cycle corresponding to the second preset angle is called the second duty cycle.

[0080] The range of the duty cycle of the control signal is between the first duty cycle and the second duty cycle. In this way, the range that the wireless control module can adjust is between the minimum brightness and the maximum brightness of the lamp beads.

[0081] Figure 3 is a schematic diagram of a brightness adjustment bar of a display interface of an intelligent terminal provided by an embodiment of the present application. As shown in Figure 3 The target user can set the first duty cycle and the second duty cycle of the triac dimmer 110 through the display interface of the intelligent terminal. The conduction angle of the triac dimmer 110 is between the first preset angle and the second preset angle, and the range of the duty cycle of the control signal that the target user can adjust is between the first duty cycle and the second duty cycle.

[0082] Optionally, Figure 4 is a schematic diagram of a triac conduction angle corresponding to a duty cycle adjustable range provided by an embodiment of the present application. Figure 5 is a schematic diagram of a triac conduction angle corresponding to a duty cycle adjustable range provided by an embodiment of the present application. Figure 6 is another schematic diagram of a triac conduction angle corresponding to a duty cycle adjustable range provided by an embodiment of the present application. Based on the above embodiment, in combination with Figures 1 to 4 The wireless control module is specifically configured to: when the conduction angle data of the triac dimmer 110 is unchanged, generate a first control signal in response to a gesture operation adjustment instruction. The control signal includes the first control signal, and when the conduction angle data of the current triac dimmer 110 corresponds to a first target duty cycle of the control signal, the range of the duty cycle of the first control signal is between the first duty cycle and the first target duty cycle; the first target duty cycle is less than or equal to the second duty cycle.

[0083] When the conduction angle data of the SCR dimmer 110 is adjusted from the first conduction angle to the second conduction angle, a second control signal is generated; wherein, the control signal includes a second control signal, the first conduction angle of the SCR dimmer 110 corresponds to the second target duty cycle of the control signal, and the second conduction angle of the SCR dimmer 110 corresponds to the third target duty cycle of the control signal; the duty cycle of the second control signal is first adjusted back to the second target duty cycle from the current duty cycle, and then adjusted to the third target duty cycle from the second target duty cycle.

[0084] Specifically, in one possible application scenario, the target user adjusts the SCR lamps via a smart terminal instead of operating the SCR dimmer 110. (See [link to relevant documentation]). Figure 4 When the conduction angle of the thyristor dimmer 110 is fixed at a certain value between the first preset angle and the second preset angle, for example... Figure 4 The first angle θ1 in the diagram refers to the duty cycle corresponding to the conduction angle of the current SCR dimmer 110, which is the first target duty cycle. It should be noted that the first target duty cycle is between the first duty cycle and the second duty cycle, and the first target duty cycle is less than or equal to the second duty cycle. When the target user adjusts the device via a smart terminal, the device responds to the target user's operation command and generates a first control signal. The duty cycle corresponding to the first control signal is between the first duty cycle and the first target duty cycle.

[0085] Another possible application scenario is that the target user adjusts the SCR lamp via a smart terminal to make the light brightness correspond to the current duty cycle. Then, without using the smart terminal, the target user adjusts the SCR lamp by operating the SCR dimmer 110. See also... Figure 5 and Figure 6 When the conduction angle of the SCR dimmer 110 is adjusted from the current angle to another conduction angle, for example, the current conduction angle of the SCR dimmer 110 is the first conduction angle θ1, and the target conduction angle of the SCR dimmer 110 is the second conduction angle θ2. The duty cycle of the control signal corresponding to the first conduction angle θ1 is the second target duty cycle, and the conduction angle corresponding to the second conduction angle θ2 is the third target duty cycle. When the target user adjusts the brightness of the SCR lamp through the SCR dimmer 110, a second control signal is generated. The duty cycle of the second control signal is gradually adjusted from the current duty cycle back to the second target duty cycle, and then gradually adjusted from the second target duty cycle to the third target duty cycle. Due to the presence of the wireless adjustment module 140, the current duty cycle of the second control signal may not be equal to the second target duty cycle.

[0086] It should be noted that, Figure 5The third target duty cycle is greater than the second target duty cycle, and the second target duty cycle is greater than the current duty cycle of the second control signal. When the angle of the triac dimmer 110 is adjusted from the first conduction angle θ1 to the second conduction angle θ2, the duty cycle corresponding to the second control signal is first adjusted from the current duty cycle less than the second target duty cycle to the second target duty cycle, and then adjusted from the second target duty cycle to the third target duty cycle.

[0087] Figure 6 The third target duty cycle is greater than the second target duty cycle, and the second target duty cycle is greater than the current duty cycle of the second control signal. When the angle of the triac dimmer 110 is adjusted from the first conduction angle θ1 to the second conduction angle θ2, the duty cycle corresponding to the second control signal is first adjusted from the current duty cycle less than the second target duty cycle to the second target duty cycle, and then adjusted from the second target duty cycle to the third target duty cycle.

[0088] Yet another optional application scenario, Figure 6a is a schematic diagram of an adjustable duty cycle range of a display interface of a smart terminal provided by an embodiment of the present application. When the adjustable range of the duty cycle of the smart terminal is unchanged, the first preset angle of the conduction angle data is matched with the first duty cycle of the control signal, and the conduction angle data of the current triac dimmer is matched with the second duty cycle of the control signal. The second duty cycle of the actual output of the control signal is the product of the conduction angle data of the current triac dimmer and the brightness ratio of the triac lamp. The brightness ratio of the triac lamp is the ratio of the conduction angle data of the current triac dimmer to the conduction angle corresponding to the maximum brightness of the triac lamp.

[0089] Specifically, when the duty cycle of the display of the smart terminal is constant and unchanged, for example, the adjustable range of the duty cycle of the triac lamp displayed on the smart terminal is 1%-100% adjustable, and the second duty cycle of the actual output of the control signal is the product of the conduction angle data of the current triac dimmer and the brightness ratio of the triac lamp. The brightness ratio of the triac lamp is the ratio of the conduction angle data of the current triac dimmer to the conduction angle corresponding to the maximum brightness of the triac lamp. When the target user adjusts the conduction angle of the triac dimmer from 60° to 80°, the adjustable range of the duty cycle of the triac lamp displayed on the smart terminal is still 1%-100% adjustable. When the conduction angle of the triac dimmer is 60°, the 100% duty cycle of the triac lamp displayed on the smart terminal corresponds to the maximum brightness of the triac lamp with a conduction angle of 60°. When the conduction angle of the triac dimmer is 80°, the 100% duty cycle of the triac lamp displayed on the smart terminal corresponds to the maximum brightness of the triac lamp with a conduction angle of 80°. Figure 7 is a schematic diagram of the change of the adjustable duty cycle range of the display interface of the smart terminal corresponding to the conduction angle of the triac.Figure 8 is another intelligent terminal display interface adjustable duty cycle range corresponding to the thyristor conduction angle change schematic diagram provided by the embodiment of the application. The target user intelligent terminal adjustable duty cycle range changes with the thyristor conduction angle range.

[0090] Referring to Figure 7 , for example, in the case that the third target duty cycle is greater than the second target duty cycle, and the second target duty cycle is greater than the current duty cycle of the second control signal, the duty cycle corresponding to the second control signal is first adjusted to the second target duty cycle, and then adjusted to the third target duty cycle from the second target duty cycle. When the conduction angle of the thyristor dimmer 110 changes, the target user adjustable duty cycle range also changes.

[0091] Referring to Figure 8 , for example, in the case that the third target duty cycle is less than the second target duty cycle, and the second target duty cycle is greater than the current duty cycle of the second control signal, the duty cycle corresponding to the second control signal is first adjusted to the second target duty cycle, and then adjusted to the third target duty cycle from the second target duty cycle. When the conduction angle of the thyristor dimmer 110 changes, the target user adjustable duty cycle range also changes.

[0093] Specifically, the passive discharge circuit 210 adopts a capacitor-resistor series circuit to provide a maintenance current for the normal work of the thyristor dimmer 110. The passive discharge circuit 210 is arranged between the thyristor dimmer 110 and the angle detection module 120, and the angle detection module 120 can better detect the conduction angle of the thyristor dimmer 110 and the AC zero-crossing point.
