[0029] Such as Figures 1-3As shown in the figure, a taper switch compatible on-off control LED color mixing circuit according to an embodiment of the first aspect of the present invention includes a power modulation module 100, an LED assembly 200, a driving module 300, a push-and-turn control member 400, and a control module 500. The input end of the power modulation module 100 is used to connect to a power supply. The power modulation module 100 is used to modulate the input voltage of the power supply to form a supply voltage. The LED assembly 200 includes at least a first LED lamp group 210 and a second LED lamp group 220. The first LED lamp group 210 and the second LED lamp group 220 can emit light of different color temperatures. The driving module 300 includes at least a first switch unit 310 and a second switch unit 320. The first switch unit 310 is connected in series with the first LED lamp group 210 to form at least part of a first driving branch. The second switch unit 320 is connected in series with the second LED lamp group 220 to form at least part of a second driving branch. The output end of the power modulation module 100 is respectively connected to the first driving branch and the second driving branch. The push-and-turn control member 400 includes a turning part and a plurality of gear parts. The turning part is movably arranged on the push-and-turn control member 400. Applying force to the turning part can switch the cooperation between the turning part and different gear parts. The cooperation between the turning part and different gear parts can cause the push-and-turn control member 400 to output different control signals. The control module 500 is respectively connected to the output end of the power modulation module 100, the push-and-turn control member 400, the controlled end of the first switch unit 310, and the controlled end of the second switch unit 320. The control module 500 can respectively output PWM signals to control the on-off operation of the first switch unit 310 and the second switch unit 320. The control module 500 can change the working currents of the first LED lamp group 210 and the second LED lamp group 220 according to different control signals or according to the on-off signals output by the power modulation module 100.

[0030] Among them, the push-and-turn control member 400 may include a housing for placing on a wall or a tabletop. The turning part may be a lever movably arranged on the housing. A first conductive member is arranged inside the lever. Each gear part may be provided with a second conductive member. The lever moves so that the first conductive member switches to contact different second conductive members to achieve electrical connection. The first conductive member and different second conductive members output different control signals. It should be noted here that the difference in the control signals can be reflected in different signal frequencies or can also be reflected in the same signals output from different ports.

[0031] The control module 500 can be selected from a conventional MCU, CPU or other processing chips. The control module 500 can output PWM signals with different duty cycles to the first switching unit 310 and the second switching unit 320. Specifically, a third switching unit and a third LED lamp group can also be adaptively added. Both the first switching unit 310 and the second switching unit 320 can use semiconductor switching tubes, such as Figure 3 As shown, the first switching unit 310 includes a switching tube Q2, and the second switching unit 320 includes a switching tube Q3. The PWM signal is output to the switching tube Q2 and the switching tube Q3. The switching tubes will cause the first LED lamp group 210 and the second LED lamp group 220 to turn on and off according to the duty cycle of the PWM signal. The control module 500 changes the working current of the first LED lamp group 210 and the second LED lamp group 220 according to different manipulation signals. Since the color temperatures of the first LED lamp group 210 and the second LED lamp group 220 are different, when the lighting interval of the first LED lamp group 210 increases and the corresponding extinguishing interval shortens, at the same time, the lighting interval of the second LED lamp group 220 shortens and the extinguishing interval increases, the mixed light color of the LED assembly 200 tends to the color temperature of the first LED lamp group 210, and vice versa. Thus, the light emitting color of the LED assembly 200 can be changed. Similarly, the enable terminal of the control module 500 can be connected to the output terminal of the power supply adjustment module 100. While the power supply adjustment module 100 outputs a supply voltage to power the control module 500, the control module 500 can also sample the on-off signal. The control module 500 can also change the working current of the first LED lamp group 210 and the second LED lamp group 220 according to different on-off signals. It should be noted that for the on-off signal that can change the working current of the first LED lamp group 210 and the second LED lamp group 220, the time interval of on-off switching is usually set to be relatively short, such as the on-off switching time is within 0.5 s, 1 s, etc.

[0032] The push-pull switch of the utility model is compatible with the on-off control LED color adjustment circuit. When the user needs to adjust the luminous color, force can be applied to the toggle part to switch the toggle part to cooperate with the appropriate gear part. The toggle part cooperates with different gear parts to enable the push-pull control member 400 to output different control signals. The control module 500 changes the working current of the first LED light group 210 and the second LED light group 220 according to the different control signals. Alternatively, the user controls the power supply input power modulation module 100 to form an on-off signal by turning on and off the power supply voltage of the power modulation module 100. The control module 500 can also continuously change the working current of the first LED light group 210 and the second LED light group 220 according to the on-off signal. When the working current of the first LED light group 210 and the second LED light group 220 changes, the mixed light color of the first LED light group 210 and the second LED light group 220 also changes accordingly to achieve color adjustment. The present design is convenient and reliable to use, simple to operate, and meets user needs.

[0033] In some embodiments of the present invention, Figure 3 As shown, the first LED lamp group 210 includes a first LED lamp string, and the first LED lamp string includes a plurality of first LED lamp beads connected in series in sequence. The output end of the power modulation module 100 is connected to the positive pole of the first LED light string, the negative pole of the first LED light string is connected to the input end of the first switch unit 310, and the output end of the first switch unit 310 is grounded.

[0034] Specifically, the first LED lamp string may further include more first LED lamp beads, and more first LED lamp beads may be connected in parallel with the first LED lamp beads in the first LED light string. The multiple first LED lamp beads are composed of a combination of multiple warm white LED lamp wicks and multiple cool white LED lamp wicks, and a corresponding number of warm white LED lamp wicks and a corresponding number of cool white LED lamp wicks are configured according to the color temperature value required by the first LED lamp group 210, or the luminous color temperature of the warm white LED lamp wicks and the cool white LED lamp wicks are selected.

[0035] In some embodiments of the present invention, the second LED light group 220 includes a second LED light string, the second LED light string includes a plurality of second LED lamp beads connected in series in sequence, the output end of the power modulation module 100 is connected to the positive pole of the second LED light string, the negative pole of the second LED light string is connected to the input end of the second switch unit 320, and the output end of the second switch unit 320 is grounded.

[0036] Specifically, the second LED light string may further include more second LED lamp beads, and more second LED lamp beads may be connected in parallel with the second LED lamp beads in the second LED light string. The multiple second LED lamp beads are composed of a combination of multiple warm white LED lamp wicks and multiple cool white LED lamp wicks, and a corresponding number of warm white LED lamp wicks and a corresponding number of cool white LED lamp wicks are configured according to the color temperature value required by the second LED light group 220, or the luminous color temperature of the warm white LED lamp wicks and the cool white LED lamp wicks are selected.

[0037] In some embodiments of the present invention, Figure 3 As shown, the push-to-push control member 400 includes a plurality of gear output terminals, and the control module 500 includes a plurality of gear receiving terminals connected to the gear output terminals in a one-to-one correspondence. When the push-to-push part cooperates with different gear parts, the corresponding gear output terminal outputs a control signal.

[0038] The first conductive member of the push-to-push control member 400 can be connected to a low-voltage 3.3V or 5V power supply, and the second conductive member can be connected to the gear output terminal one by one. When the user drives the push-to-push part to move, so that the first conductive member is selectively connected to any second conductive member, the corresponding gear output terminal outputs a control signal to the gear receiving terminal. The control signal here is a level signal. When different gear receiving terminals of the control module 500 receive the control signal, the operating current of the first LED light group 210 and the second LED light group 220 is changed.

[0039] In some embodiments of the present invention, the push-to-pull control member also includes a locking portion, and applying force to the toggle portion can switch the toggle portion and the locking portion to cooperate. When the toggle portion cooperates with the locking portion, the control module changes the operating current of the first LED light group and the second LED light group according to the on-off signal output by the power modulation module. When the toggle portion cooperates with the gear portion, the control module changes the operating current of the first LED light group and the second LED light group according to different control signals. This is equivalent to that when the toggle portion cooperates with each gear portion, even if the control module receives an on-off signal, the control module will not change the operating current of the first LED light group 210 and the second LED light group 220. Only when the toggle portion cooperates with the locking portion will the control module change the operating current of the first LED light group 210 and the second LED light group 220 according to the on-off signal.

[0041] Among them, the rectification unit 110 can be a full-wave rectifier bridge or a half-wave rectifier bridge. The power supply can be an AC mains supply. After the rectification unit 110 rectifies the alternating current, it provides it to the switching power supply voltage regulation unit 120 for voltage modulation to form a supply voltage suitable for the operation of the LED assembly 200.

[0042] In some embodiments of the present invention, as Figure 2 shown, the switching power supply voltage regulation unit 120 includes a switching power supply chip 121, a semiconductor switching tube Q1, and an output voltage detection component 122. The output end of the rectification unit 110 is respectively connected to the input end of the switching tube Q1, the sampling end of the output voltage detection component 122, the first drive branch, and the second drive branch. The output end of the output voltage detection component 122 is connected to the switching power supply chip 121. The output end of the switching tube Q1 is grounded, and the switching power supply chip 121 is connected to the controlled end of the switching tube Q1.

[0043] The output voltage detection component 122 detects the magnitude of the supply voltage and then feeds it back to the switching power supply chip 121. The switching power supply chip 121 changes the on-off duty cycle of the switching tube Q1 to adjust the magnitude of the supply voltage. For example, when the supply voltage increases, the switching power supply chip 121 controls the conduction duration of the switching tube Q1 to increase, so that the supply voltage can be decreased. Specifically, the output voltage detection component 122 can include a sampling resistor R2.

[0044] In some embodiments of the present invention, the switching power supply voltage regulation unit 120 further includes an input voltage detection component 123 and a diode D1.

Specifically, the input voltage detection component 123 includes a resistive voltage division circuit formed by a resistor R4, a resistor R5, and a capacitor C2.

The input end of the power modulation module 100 is connected to the power supply through the main switch component 600. Operating the main switch component 600 can switch the switch state of the main switch component 600. The main switch component 600 can be independent of the push-pull control member 400. The main switch component 600 can be a main power switch set on the wall, which is used to press the main switch component 600 to control the start and stop of the LED component. The main switch component 600 can also be integrated in the push-pull control member 400. Toggle the push-pull control member 400 to start and stop the power supply input, thereby controlling the start and stop of the LED component. Specifically, the user can operate the main switch component 600 to form an on-off signal.
