[0026] Embodiment 1

[0027] Reference Figure 1 - Figure 2 , this embodiment provides a circuit for networking devices based on the mains power, including a mains power conversion circuit, a sensor, and slave devices;

[0028] The input end of the mains power conversion circuit is connected to the mains power, and the output end is connected to the drive circuit and the signal detection circuit of the slave devices;

[0029] The drive circuit is used to drive the LED in the slave device to work with the voltage output by the mains power conversion circuit;

[0030] The signal detection circuit is used to detect the waveform output by the mains power conversion circuit and output different signals to the drive circuit through different waveforms. The drive circuit drives the LED in the slave device to work in a corresponding mode according to the received signal.

[0031] In this embodiment, the different waveforms refer to full-wave or half-wave waveforms output by the mains conversion circuit. Of course, other waveforms are also possible, which are simple replacements in this embodiment. The LED operating mode corresponding to the full-wave waveform is full brightness; the LED operating mode corresponding to the half-wave waveform is 10% brightness. The specific operating mode can also be adjusted according to actual needs, which also belongs to the simple replacement of this embodiment.

[0032] To achieve different waveforms output by the mains conversion circuit, the mains conversion circuit includes a relay; the first port of the relay is directly connected to the live wire L1, the second port is connected to the live wire L2 through a first diode, and the third port is connected to the live wire L3 through a second diode; the first diode and the second diode are arranged in reverse. The fourth port of the relay is connected to the AC input terminal of the rectifier bridge, and the other AC input terminal of the rectifier bridge is connected to the neutral wire. For example, when connecting L1-N, the original mains sine wave is output; when connecting L2-N, the upper half-wave is output; when connecting L3-N, the lower half-wave is output; when connecting V+ and V-, the DC voltage after full-bridge rectification is output.

[0033] Embodiment 2

[0034] Reference Figure 3 - Figure 4 Furthermore, the present utility model also provides a device networking circuit based on the mains, including a master device and a slave device; the master device includes a mains conversion circuit and a sensor; the input terminal of the mains conversion circuit is connected to the mains, and the output terminal is connected to the drive circuits and signal detection circuits of the master device and the slave device; the drive circuits are used to drive the LEDs in the master device and the slave device with the voltage output by the mains conversion circuit; the signal detection circuit is used to detect the waveforms output by the mains conversion circuit and output different signals to the drive circuits according to different waveforms, and the drive circuits drive the LEDs of the slave device to operate in the corresponding modes according to the received signals.

[0035] In this embodiment, the different waveforms refer to full-wave or half-wave waveforms output by the mains conversion circuit. Of course, other waveforms are also possible, which are simple replacements in this embodiment. The LED operating mode corresponding to the full-wave waveform is full brightness; the LED operating mode corresponding to the half-wave waveform is 10% brightness. The specific operating mode can also be adjusted according to actual needs, which also belongs to the simple replacement of this embodiment.

[0036] To achieve different waveforms at the output of the mains conversion circuit, the mains conversion circuit includes a relay. The first port of the relay is directly connected to the live wire L1, the second port is connected to the live wire L2 through a first diode, and the third port is connected to the live wire L3 through a second diode. The first diode and the second diode are arranged in reverse. The fourth port of the relay is connected to the AC input terminal of the rectifier bridge, and the other AC input terminal of the rectifier bridge is connected to the neutral wire. For example, when connecting L1-N, the original mains sine wave is output; when connecting L2-N, the upper half wave is output; when connecting L3-N, the lower half wave is output; when connecting V+ and V-, the DC voltage after full-bridge rectification is output.

[0037] Taking the above networking circuit as an example, the sensor is selected as a human body induction sensor. For example, when the human body induction sensor is built-in, when a person walks near the lamp, the sensor senses the signal. When the main device adjusts to the brightest, the mains conversion is carried out simultaneously. For example, the mains is converted into a positive half wave, and the converted mains is transmitted to the slave devices at the back end. The converted mains not only supplies power to the slave devices at the back end, but also provides information about the current state of the main lamp to the slave devices at the back end. For example, the waveform converted when the main lamp is fully lit is a full wave, and the waveform converted when the main lamp is at 10% brightness is a half wave. The slave devices at the back end will judge whether to output full brightness or 10% brightness according to whether all positive half waves or negative half waves are detected.

[0038] The above is only a preferred specific embodiment of the present invention, and does not limit the patent scope of the present invention. All technical equivalent transformations made using the content of the specification of the present invention fall within the protection scope of the present invention.
