Description

Technical Field

[0001] The utility model relates to an adaptive dimming double-control switch. Background Art

[0002] Currently, only single-burner dimmer switches are available on the market. These single-control switches offer simple and direct control, making them suitable for single-user scenarios. For example, in a typical bedroom or living room, a single switch is often sufficient to control the light's on / off state. In this scenario, single-control switches are simple, practical, and easy to operate, making them suitable for everyday home use. However, their disadvantage is their limited flexibility, as they can only be controlled by a single switch, making them inconvenient. Utility Model Content

[0003] In view of the above problems, the utility model provides an adaptive dimming double-control switch.

[0005] Furthermore, the power supply unit includes two groups of power supply units, one group of power supply units is connected to the drive unit to supply power to the power supply unit; another group of power supply units is connected to the mutual control unit to supply power to the mutual control unit, and another group of power supply units is connected to the DC / DC unit, and the DC / DC unit converts 12V power into 3.3V power to power the MCU.

[0006] Furthermore, a zero-crossing detection unit for triggering the lamp at the zero point of the AC power is connected to the MCU.

[0007] The beneficial effects of the present invention are that the electric light can be controlled at different positions, and no rewiring is required during household installation. If the old rocker switch has a double control line, it can be installed. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to specific embodiments and accompanying drawings:

[0018] Example 1, refer to the attached Figure 1-9 As shown, an adaptive dimming dual-control switch includes a power supply unit, a DC / DC unit, a drive unit, a dimmer switch, an inter-control unit and an MCU. The power supply unit is connected to the inter-control unit, the DC / DC unit and the drive unit. The inter-control unit, the DC / DC unit and the drive unit are all connected to the MCU; the drive unit is connected to the lamp, and the inter-control unit is connected to the dimmer switch.

[0019] An adaptive dimming double-control switch, the power supply unit includes two groups of power supply units, one group of power supply units is connected to the driving unit to supply power to the power supply unit, such as Figure 2 Another set of power supply units is connected to the mutual control unit to supply power to the mutual control unit, and another set of power supply units is connected to the DC / DC unit. The DC / DC unit converts the 12V power supply into a 3.3V power supply to supply power to the MCU. Figure 3 .

[0020] An adaptive dimming dual-control switch realizes that the zero-crossing detection unit of the lamp is connected to the MCU when the lamp is triggered at the zero point of the AC power. Figure 4 、 Figure 5 .

[0021] An adaptive dimming dual-control switch, driving unit, uses dual MOS to realize the dimming function of the lamp. The MCU outputs the PWM signal to U3, and U3 outputs the corresponding PWM waveform to chop the lamp L1 through the dual MOS, thereby realizing the control function of the lamp brightness, such as Figure 6 .

[0022] An adaptive dimming double-control switch, mutual control unit, can realize the mutual control function of two dimmer switches:

[0023] Step 1: Use the live wire as the ground, the COM port is both the power line and the data communication transmission line, a single data bus method (such as Figure 7 ).

[0024] Step 2: MCU controls the uc_com_out pin to pull up the level, and the other switch uc_com_in inputs to the MCU pin and receives a low level signal, and vice versa. In this way, relevant protocols can be formulated for communication, thereby realizing mutual control functions (such as Figure 8 ).

[0025] Although the present invention has been illustrated and described with reference to preferred embodiments, it will be understood by those skilled in the art that it is not limited to the description of the above embodiments and that various changes in form and details may be made within the scope of the claims.
