Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0031] This embodiment provides a device networking method based on mains power. A control signal output module outputs control signals to a mains power conversion circuit. The mains power conversion circuit converts the mains power into different waveforms according to different control signals and outputs them to the downstream slave devices for power supply. The downstream devices detect the waveforms output by the mains power conversion circuit and drive the devices to operate in the corresponding modes. In this embodiment, the control signal output module is a sensor.

[0032] Example 1

[0033] Referring to Figures 1-4, this embodiment provides a device networking circuit based on mains power, including a mains power conversion circuit, a control signal output module, and slave devices;

[0034] The input terminal of the mains power conversion circuit is connected to the mains power, and the output terminal is connected to the drive circuit and signal detection circuit of the slave device.

[0035] The driving circuit is used to drive the LED in the device to work using the voltage output from the mains power conversion circuit. As a simple alternative to this embodiment, the driving circuit obtains voltage from other lines to drive the LED to work. Using the voltage output from the mains power conversion circuit achieves the simplest solution in terms of the line, but it is not the only feasible solution.

[0036] The signal detection circuit is used to detect the waveform output by the mains power conversion circuit, and outputs different signals to the driving circuit through different waveforms. The driving circuit drives the LED in the slave device to work in the corresponding mode according to the received signal.

[0037] In this embodiment, the different waveforms refer to the full-wave or half-wave waveform output by the mains power conversion circuit. Of course, other waveforms can also be used, which are simple substitutions in this embodiment. The full-wave waveform corresponds to a fully bright LED operating mode; the half-wave waveform corresponds to a 10% brightness LED operating mode. The specific operating mode can also be adjusted according to actual needs, which is also a simple substitution in this embodiment. For example, the half-wave waveform corresponds to a 90% brightness LED operating mode; as long as it is not fully bright, this percentage of brightness can be adjusted arbitrarily.

[0038] Referring to Figure 3, in addition to full-wave and half-wave waveforms, the waveform output by the mains power conversion circuit can also be a chopped waveform, a carrier waveform, or a waveform with altered amplitude or frequency. The half-wave waveform can be either the upper or lower half of a full-wave waveform, or either the upper or lower half of a full-wave waveform.

[0039] Referring to Figure 4, to achieve different waveforms output by the AC power conversion circuit, the AC power conversion circuit includes a relay; wherein 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 the first diode, and the third port is connected to the live wire L3 through the second diode; wherein the first diode and the second diode are reversed. 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 connected to L1-N, the original AC sine wave is output; when connected to L2-N, the upper half-wave is output; when connected to L3-N, the lower half-wave is output; and when connected to V+ and V-, the DC voltage after full-bridge rectification is output.

[0040] Example 2

[0041] Referring to Figures 5 and 6, the present invention also provides a device networking circuit based on mains power, including a master device and a slave device; the master device includes a mains power conversion circuit and a control signal output module; the input terminal of the mains power conversion circuit is connected to the mains power, and the output terminal is connected to the drive circuit and signal detection circuit of the master device and the slave device; the drive circuit is used to drive the LEDs in the master device and the slave device to work using the voltage output by the mains power conversion circuit; 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, and the drive circuit drives the LEDs of the slave device to work in the corresponding mode according to the received signals.

[0042] In this embodiment, the different waveforms refer to the full-wave or half-wave waveform output by the mains power conversion circuit. Of course, other waveforms can also be used, which are simple substitutions in this embodiment. The full-wave waveform corresponds to a fully lit LED operating mode; the half-wave waveform corresponds to a 10% brightness LED operating mode. The specific operating mode can also be adjusted according to actual needs, which are also simple substitutions in this embodiment.

[0043] To achieve different waveforms output from the AC power conversion circuit, the AC power 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 via a first diode, and the third port is connected to the live wire L3 via a second diode; the first and second diodes are reverse-biased. 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 connected to L1-N, the original AC sine wave is output; when connected to L2-N, the upper half-wave is output; when connected to L3-N, the lower half-wave is output; and when connected to V+ and V-, the DC voltage after full-bridge rectification is output.

[0044] Taking the above-mentioned network circuit as an example, the control signal output module is selected as a human body induction control signal output module. For example, when the human body induction control signal output module is built-in, when a person walks near the light, the control signal output module senses the signal. When the main device adjusts to the brightest setting, it simultaneously performs mains power conversion, for example, converting the mains power to a positive half-wave. The converted mains power is then transmitted to the slave device at the back end. The converted mains power not only powers the slave device at the back end but also provides it with information about the current status of the main light. For example, the waveform when the main light is fully bright is a full wave, and the waveform when the main light is at 10% brightness is a half wave. The slave device at the back end will determine whether the output is fully bright or at 10% brightness based on whether the detected waveforms are positive or negative half-waves.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Any technically equivalent modifications made based on the content of this specification shall fall within the protection scope of the present invention. Industrial applicability
