Abstract
Description
Technical Field
[0001] This utility model relates to the field of power controller technology, and more specifically, to a power controller based on button control. Background Technology
[0002] With the development of technology, LED lights are being used more and more widely. String lights are installed during some holidays, such as Christmas, to create a festive atmosphere. LED string lights refer to strips of light formed by assembling LEDs onto a flexible, strip-shaped circuit board.
[0003] Currently, most string light controls on the market use physical buttons to start or stop them. However, these physical buttons act as a master switch, only allowing the lights to be turned on and off. To improve the display effect of the string lights, existing technologies have added wireless remote control functionality. Signals emitted by the wireless remote control allow for different lighting modes, brightness levels, and durations of illumination.
[0004] However, in actual use, the wireless remote control is not always placed next to the light string. When the light string needs to be adjusted, the operator needs to find the corresponding remote control before making adjustments. This results in untimely and inflexible control of the light string. Utility Model Content
[0005] The technical problem to be solved by this invention is that the existing technology cannot adjust the display of light strings in a timely manner. In order to overcome the above-mentioned defects of the existing technology, this invention provides a power controller based on button control.

[0007] A power supply module, wherein the input terminal of the power supply module is electrically connected to the live wire and the neutral wire;
[0008] The main control module is electrically connected to the output terminal of the power supply module.
[0009] A button control module includes a button and a timer indicator. The positive terminal of the timer indicator is electrically connected to the output terminal of the power supply module, and the negative terminal of the timer indicator is connected in series with the button and then grounded. The connection terminal of the negative terminal of the timer indicator and the button is electrically connected to the main control module. The main control module drives the timer indicator to light up or turn off according to the number of times the button is pressed.
[0010] The driving module has its input terminal electrically connected to the main control module and its output terminal electrically connected to the light string. The main control module controls the driving module to adjust the display mode, display time, and display brightness of the light string based on the number of button presses and the trigger duration signal received.
[0011] Compared with the prior art, the power controller based on button control proposed in this application has the following advantages: a button control module is set on the power controller, and the display mode, display time and display brightness of the light string are adjusted by the number of button presses and the trigger duration.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0024] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0025] See Figure 1 As shown in the figure, this application discloses a power controller based on button control, including:
[0026] The power supply module has its input terminals connected to the live wire and the neutral wire.
[0027] The main control module is electrically connected to the output terminal of the power supply module.
[0028] The button control module includes a button and a timer indicator. The positive terminal of the timer indicator is electrically connected to the output terminal of the power supply module, and the negative terminal of the timer indicator is connected in series with the button and then grounded. The connection terminal of the negative terminal of the timer indicator and the button is electrically connected to the main control module. The main control module drives the timer indicator to light up or turn off according to the number of times the button is pressed.
[0029] The driver module has its input terminal electrically connected to the main control module and its output terminal electrically connected to the light string. The main control module controls the driver module to adjust the display mode, display time, and display brightness of the light string based on the number of button presses and the trigger duration signal received.
[0030] A button control module is set on the power controller. The number of button presses and the trigger duration control the drive module to adjust the lighting mode, lighting time and lighting brightness of the light string. The light string is directly connected to the power controller, which can adjust the display of the light string in a timely manner and make the control more flexible.
[0031] In actual operation, if the button is pressed once within a preset time (the time is timed by the crystal oscillator of the main control module), the main control module will detect the press and control the drive module to adjust the light string to enter the next display mode.
[0032] If the button is pressed twice within a preset time, the main control module will control the drive module to adjust the display duration of the light string, thus enabling the light string to have a timer function.
[0033] Within a preset time, the main control module continuously detects the button being pressed and controls the drive module to adjust the brightness of the light string display.

Once the preset time is reached, the main control module drives the driver module to turn off the LED string. This is existing technology and will not be described in detail here.
[0036] Adjusting the brightness of the LED string display via the driver module involves the main control module adjusting the duty cycle of the signal input to the driver module.

The connection terminal of resistor R13 and capacitor C10 is electrically connected to the power supply terminal of the main control module. The negative terminal of diode D7 is electrically connected to the power supply terminal of the drive module.
[0042] By setting diode D7, short-circuit current is prevented from entering one end of the transformer when the driver module and the lamp string are short-circuited, thus preventing power supply damage; and by setting capacitor C10 and Zener diode ZD1, voltage regulation and filtering are achieved to ensure the stability of the output power signal.
