In one embodiment, as shown in fig. 1, there is provided a switching regulator circuit comprising:
a rectifying circuit 110 for connecting to a mains line; the rectification circuit is connected with the mains supply circuit through a switch;
the input end of the power supply circuit 120 is connected with the rectifying circuit;
a voltage division circuit 130, a first end of which is connected with the rectification circuit; the voltage division circuit is used for outputting a first voltage signal when the switch is disconnected; when the switch is conducted, outputting a second voltage signal;
the power supply end of the controllable IC chip is connected with the output end of the power supply circuit, the output end of the controllable IC chip is used for being connected with a lamp, and the voltage detection end of the controllable IC chip is connected with the second end of the voltage division circuit; the controllable IC chip is used for transmitting a driving signal with corresponding current percentage to the lamp according to the first voltage signal and the second voltage signal.
The rectifier circuit 110 is a circuit that converts ac power into dc power; the rectifying circuit 110 may be used to rectify an ac power transmitted through a utility line and output a dc power. Alternatively, the rectifying circuit 110 may be a half-wave rectifying circuit, a full-wave rectifying circuit, or a bridge rectifying circuit. A utility line refers to a line that transmits mains frequency alternating current (e.g., 50 hz alternating current). A switch refers to an electronic component that can open a circuit, interrupt a current, or cause it to flow to other circuits; for example, the switch may be a wall switch. The power supply circuit 120 can be used for converting the direct current output by the rectifying circuit into an electric signal conforming to the power supply of the controllable IC chip; for example, the power supply circuit 120 may output a 30 volt voltage signal. The voltage dividing circuit 130 is used for dividing and outputting the direct current output by the rectifying circuit; for example, when the switch is turned off, the circuit is in an open circuit state, and the amplitude of the first voltage signal output by the voltage dividing circuit 130 is 0 v; when the switch is turned on, the circuit is in a pass state, and the amplitude of the second voltage signal output by the voltage dividing circuit 130 is a voltage value after corresponding voltage division. The controllable IC chip 140 refers to a constant current LED driving chip with a switching step dimming function; for example, the controllable IC chip 140 may be a single-channel high-voltage linear constant-current LED driving chip.
Optionally, the lamp can be an LED ceiling lamp, an LED bulb lamp, an LED filament lamp or an LED fluorescent lamp tube.
Specifically, the switch is connected between the rectifying circuit 110 and the commercial power line based on the fact that the rectifying circuit 110 is connected with the commercial power line; the input end of the power supply circuit 120 is connected with the rectifying circuit 110, and the output end of the power supply circuit 120 is connected with the power supply end of the controllable IC chip 140; a first end of the voltage division circuit 130 is connected with the rectification circuit 110, and a second end of the voltage division circuit 130 is connected with a voltage detection end of the controllable IC chip 140; the output of the controllable IC chip 140 is used to connect to a lamp. The user can operate the on-off of the switch, and when the switch is switched off, the controllable IC chip 140 can receive the first voltage signal output by the voltage division circuit 130; when the switch is turned on, the controllable IC chip 140 may receive the second voltage signal output by the voltage dividing circuit 130; the controllable IC chip 140 may transmit a driving signal with a corresponding current percentage to the lamp according to the receiving interval time between the first voltage signal and the second voltage signal and the number of times the first voltage signal and the second voltage signal are received, so that the lamp illuminates with a corresponding brightness.
For example, when the user operates the switch for the first time to turn off or turn on, the controllable IC chip 140 may transmit a driving signal with a first current percentage (e.g., 100%) to the lamp according to the receiving interval between the first voltage signal and the second voltage signal, so that the lamp is illuminated with a first brightness (e.g., 100% brightness). When the user operates the switch for the second time to turn off or turn on, the controllable IC chip 140 may transmit a driving signal of a second current percentage (e.g., 50%) to the lamp according to the receiving interval between the first voltage signal and the second voltage signal, so that the lamp is illuminated at the first brightness (e.g., 50% brightness). When the user operates the switch for the short turn-off and the short turn-on for the third time, the controllable IC chip 140 may transmit a driving signal of a third current percentage (e.g., 20%) to the lamp according to the receiving interval time between the first voltage signal and the second voltage signal, so that the lamp is illuminated at a third brightness (e.g., 20%).
It should be noted that, the controllable IC chip 140 compares the receiving interval time between the first voltage signal and the second voltage signal with the preset turn-off time by the comparator to determine the on-off state of the switch. When the switch turn-off time is greater than the minimum turn-off time and less than the maximum turn-off time, considering one-time short turn-off operation; considering a long turn-off operation when the switch turn-off time is greater than the maximum turn-off time; when the switch on time is greater than the minimum on time and less than the maximum on time, the operation is regarded as a short on operation; a long on operation is considered when the switch on time is greater than the maximum on time.
Among the above-mentioned switch regulation and control circuit, through the short turn-off and the short operation of opening of switch, controllable IC chip 140 can switch drive signal's current percentage according to the receipt interval time between first voltage signal and the second voltage signal, realizes the brightness control to lamps and lanterns, and the switch regulation and control circuit that this application provided is small, with low costs, and the practicality is strong, can be suitable for multiple lamps and lanterns.
In one embodiment, as shown in fig. 2, controllable IC chip 140 includes a logic controller 142, a memory 144, a voltage detection module 146, a counter 148, and a voltage controlled current source 222. The logic controller 142 is connected to the memory 144, the voltage detection module 146, the counter 148 and the voltage controlled current source 222.
The voltage detection module 146 is configured to detect the first voltage signal and the second voltage signal, and transmit the first voltage signal and the second voltage signal to the logic controller 142; the logic controller 142 is configured to trigger the counter 148 to count when receiving the first voltage signal until receiving the second voltage signal, and according to the count data of the counter 148, retrieve the corresponding current percentage from the memory 144, and transmit a driving signal corresponding to the current percentage to the voltage-controlled current source 222, so that the voltage-controlled current source 222 drives the lamp to perform corresponding brightness illumination.
The logic controller 142 may be configured to compare the count data between the first voltage signal and the second voltage signal with a preset off time, and the logic controller 142 may be further configured to retrieve and transmit a driving signal of the current percentage of the memory 144. The voltage detection module 146 may be used to detect the first voltage signal and the second voltage signal of the output of the voltage divider circuit. A counter 148 may be used to count the switch off time. The voltage controlled current source 222 is referred to as a voltage controlled current source. The memory 144 may be used to store current percentage information corresponding to different drive signals. In one example, the memory 144 is a non-volatile memory.
Specifically, one end of the voltage detection module 146 is connected to the voltage divider circuit 130, and the other end is connected to the logic controller 142; the input end of the voltage-controlled current source 222 is connected with the logic controller 142, and the output end is connected with the lamp; the logic controller 142 is connected to the memory 144 and the counter 148, respectively. The voltage detection module 146 may transmit the detected first voltage signal and the second voltage signal to the logic controller 142; the logic controller 142 may trigger the counter 148 to count when receiving the first voltage signal, and terminate the counter 148 to count until receiving the second voltage signal, so as to obtain the count data from the time of receiving the first voltage signal to the time of receiving the second voltage signal; the logic controller 142 may also retrieve the corresponding current percentage from the memory 144 according to the count data of the counter 148; the logic controller 142 may transmit a driving signal corresponding to the current percentage to the voltage-controlled current source 222 according to the current percentage, so that the voltage-controlled current source 222 drives the lamp to perform corresponding brightness illumination, and the brightness of the lamp is adjusted and controlled by on-off operation of the switch.
For example, the user continuously performs four short turn-off operations on the switch, and when the user operates the switch for the first time to perform short turn-off, that is, when the count data of the counter 148 satisfies the condition, the logic controller 142 calls the corresponding current percentage (e.g., one hundred percent) to the memory 144; when the user operates the switch for a short turn-off for the second time, that is, when the count data of the counter 148 satisfies the condition, the logic controller 142 calls the corresponding current percentage (e.g., fifty percent) to the memory 144; when the user operates the switch for a short turn-off for the third time, that is, when the count data of the counter 148 satisfies the condition, the logic controller 142 calls the corresponding current percentage (for example, twenty percent) to the memory 144; when the user operates the switch for the fourth time to turn off the switch for a short time, that is, when the count data of the counter 148 satisfies the condition, the logic controller 142 calls the corresponding current percentage (e.g., one hundred percent) from the memory 144; the logic controller 142 may transmit a driving signal corresponding to the current percentage to the voltage-controlled current source 222 according to the current percentage, so that the voltage-controlled current source 222 drives the lamp to perform corresponding brightness illumination, and the brightness of the lamp is adjusted and controlled by on-off operation of the switch.
In the switch regulation circuit, the percentage of brightness regulation can be configured by the memory 144 (e.g., a nonvolatile memory); the corresponding drive current percentage may be configured by the memory 144. The driving current percentage corresponding to each switching short-off operation changes along with the change of the switching short-off operation, when the brightness of the lamp is adjusted, the logic controller 142 can adjust the corresponding current percentage stored in the memory 144, and output the driving signal corresponding to the current percentage by controlling the voltage-controlled current source 222, so that the lamp is driven to be lightened at the corresponding brightness, and the brightness adjusting function of the lamp is realized.
In a particular embodiment, after each short turn-off, the logic controller may write the current percentage of the present output to the non-volatile memory for storage. When the switch is turned on after each long-time shutdown, the logic controller can read out the current percentage stored for the last time from the nonvolatile memory and transmit a driving signal of the corresponding current percentage to the lamp through the voltage-controlled current source, so that the lamp is lightened according to the brightness of the current percentage stored for the last time, and the brightness memory function of the lamp is realized.
It should be noted that, when a plurality of lamps are connected in parallel, the switch regulation and control circuit provided by the present application can perform synchronous dimming on the plurality of lamps.
In one embodiment, as shown in FIG. 2, the controllable IC chip 140 further includes a reset circuit 224 coupled to the logic controller 142; the logic controller 142 is used for triggering the reset circuit 224 according to the counting data of the counter 148.
Wherein reset circuit 224 may be used to restore the circuit to an initial state.
For example, the logic controller 142 may determine whether the switch is in the double-click operation state according to the count data of the counter. When the switch is determined to be in the double-click operation state, the logic controller 142 may trigger the reset circuit 224, so that the output driving signal is modified to a preset reset signal; wherein a double click operation is short off-short on-short off-long on. After the double-click operation, the logic controller 142 triggers the reset circuit 224, and the reset circuit 224 reads out the current percentage corresponding to the reset signal from the nonvolatile memory, and outputs the reset signal to the lamp through the voltage-controlled current source 222 according to the current percentage corresponding to the reset signal. In one example, if more than 3 times of quick switching operations (one quick switching operation, namely short switching-short switching), the driving signal output to the lamp is also a preset reset signal, so that the user can conveniently and quickly reset the brightness of the lamp, and the practicability of switching regulation is improved.
In one embodiment, as shown in fig. 2, the controllable IC chip 142 further includes a digital-to-analog converter 226 connected between the logic controller 142 and the voltage controlled current source 222.
The digital-to-analog converter 226 may convert the data signal into an analog signal.
Specifically, based on the digital-to-analog converter 226 being connected between the logic controller 142 and the voltage-controlled current source 222, the logic controller 142 can convert the digital driving signal into the analog driving signal through the digital-to-analog converter 226; the voltage-controlled current source 222 receives an analog driving signal to drive the lamp to light at a corresponding brightness.
