[0022] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figures 1 to 7 , an embodiment of the carrier-controlled light-emitting circuit of the present invention is proposed:

[0024] A carrier-controlled lighting circuit includes a controller 1, a plurality of sensors 2, a plurality of light strips 3, and a power supply 4. The mains power is connected to the controller 1 through the power supply 4.

[0025] The controller 1 includes a power supply circuit, a main control chip, a button, a display screen, a first carrier sensor, and a modulation circuit. The power supply circuit is connected to the main control chip, the button, the display screen, the first carrier sensor, and the modulation circuit to provide power. The two output pins of the main control chip are connected to the display screen and the modulation circuit, respectively. The two input pins of the main control chip are connected to the button and the first carrier sensor, respectively.

[0026] A demodulation circuit is provided in the light strips 3 , and the light strips 3 are connected in parallel to the output end of the controller 1 .

[0027] The sensor 2 includes a sensing module and a second carrier sensor. The sensing module can be an infrared module, a microwave module, or a light sensing module.

[0028] Sensor 2 senses the surrounding environment through its sensing module and sends a signal to the first carrier sensor via the second carrier sensor. Controller 1 receives the signal from the first carrier sensor and then, through a modulation circuit, outputs an output waveform containing control information to light bar 3. Light bar 3 receives the information through a demodulation circuit and operates according to the control information. Controller 1 also controls the display to display the corresponding operating mode. The operating mode of controller 1 can be switched using a button.

[0029] Multiple operating modes can be pre-programmed into the controller 1, enabling multiple lighting modes to be realized through multiple sensors 2. The sensors 2 are placed between the light strips 3 and can detect whether there are people nearby. This allows for applications such as stair lighting and follow-up lighting, meeting the needs of a wider range of users.

[0030] For sensor 2, if it is used in a corner or a larger usage space, some sensors 2 and controller 1 are farther away or there are obstacles between them and cannot communicate directly. In this case, a group method can be adopted. Sensors 2 and sensor 2 form a sensor group, and a transmission link is set within the sensor group. The information in the same sensor group is transmitted to the designated sensor 2 and then to the controller 1.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
