The first sensor module has a first sensor range and generates a first sensor signal after detecting a moving object. The second sensor module has a second sensor range smaller than the first sensor range and generates a second sensor signal after detecting a moving object. The processing module is connected to the first sensor module, the second sensor module, and the light-emitting module. The processing module performs timing after receiving the first sensor signal and activates the light-emitting module to control it to a first brightness. If the processing module also receives a second sensor signal within a preset time interval after receiving the first sensor signal, it controls the light-emitting module to a second brightness.

[0007] In a refinement of the present invention, the second brightness is greater than the first brightness.

[0008] In one refinement of the invention, the processing module turns off the light emitting module if it does not receive the second sensor signal within a preset time interval after receiving the first sensor signal.

[0009] In one refinement of the invention, the processing module controls the light emitting module to a second brightness and turns off the light emitting module after a preset time interval has elapsed.

[0010] In a refinement of the invention, the first sensor module is a microwave sensor and the second sensor module is a body temperature sensor.

[0011] The present invention further provides a control method for a sensor illumination device, including the steps of: activating a light-emitting module and controlling the light-emitting module to a first brightness when timing is performed by a processing module after receiving a first sensor signal generated by a first sensor module having a first sensor range detecting a moving object; and controlling the light-emitting module to a second brightness when, within a preset time interval after receiving the first sensor signal, the processing module receives a second sensor signal generated by a second sensor module having a second sensor range smaller than the first sensor range detecting a moving object.

[0012] In a refinement of the present invention, the second brightness is greater than the first brightness.

[0013] In a refinement of the invention, the control method further comprises the step of turning off the light-emitting module if the processing module does not receive the second sensor signal within a preset time interval after receiving the first sensor signal.

The processing module performs timing after receiving the first sensor signal and activates the light-emitting module to control it to a first brightness. If the processing module also receives a second sensor signal within a preset time interval after receiving the first sensor signal, it controls the light-emitting module to a second brightness. The above multi-stage trigger mechanism allows the sensor lighting device to first turn on the light-emitting module after detecting a moving object and increase the brightness of the light-emitting module when the approach of the moving object is confirmed.

Therefore, the multi-stage trigger mechanism effectively reduces the power consumption of the sensor lighting device, improves the energy saving and power saving of the sensor lighting device, and reduces the impact on human eyes. (3) According to the disclosure of the present invention, the sensor illumination device comprises a first sensor module and a second sensor module. The first sensor module has a first sensor range, and the second sensor module has a second sensor range that is smaller than the first sensor range. The first sensor module is a microwave sensor, and the second sensor module is a human body temperature sensor.

For ease of understanding, the same components in the following embodiments will be denoted and described with the same reference numerals.

[0020] 1 is a block diagram of a sensor illumination device equipped with a multi-stage trigger mechanism according to a first embodiment of the present invention. As shown in the figure, the sensor illumination device 1 includes a first sensor module 11, a second sensor module 12, a light-emitting module 14, and a processing module 13.

[0021] The first sensor module 11 has a first sensor range and generates a first sensor signal after detecting a moving object. In one embodiment, the first sensor module 11 is a microwave sensor (with a detection range of 5-8 meters). In another embodiment, the first sensor module 11 may be a 10 GHz microwave sensor (with a detection range of 10 meters) or other similar components.

[0022] In another embodiment, the second sensor module 12 may be a 24GHz human body temperature sensor (with a detection distance of 2 meters), an infrared sensor, or other similar components.

[0023] The processing module 13 is connected to the first sensor module 11, the second sensor module 12, and the light-emitting module 14. In one embodiment, the processing module 13 may be a microcontroller (MCU). In another embodiment, the processing module 13 may be a central processing unit (CPU), an application specific integrated circuit chip (ASIC), a field programmable gate array (FPGA), or other similar components. In one embodiment, the light-emitting module 14 may be one or more light-emitting diodes. In another embodiment, the light-emitting module 14 may be a light bulb, a fluorescent lamp, or other similar components.

[0024] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the sensor illumination device with the multi-stage trigger mechanism of this embodiment should still fall within the protection scope of the present invention.

[0025] 2 is an explanatory diagram showing the operating state of a sensor lighting device equipped with a multi-stage trigger mechanism according to a first embodiment of the present invention. As shown in the figure, the first sensor module 11 has a wide sensor range and therefore first generates a first sensor signal S1. When the first sensor module 11 detects a moving object, it generates the first sensor signal S1 and transmits it to the processing module 13. After receiving the first sensor signal S1, the processing module 13 performs timing, activates the light-emitting module 14, and controls the light-emitting module 14 to a first brightness. In this case, since the processing module 13 has confirmed that a moving object is approaching, it activates the light-emitting module 14 and controls the light-emitting module 14 to a first brightness.

[0026] Subsequently, when the moving object also approaches the second sensor module 12, the second sensor module 12 also generates a second sensor signal S2. If the processing module 13 also receives the second sensor signal S2 within a preset time interval after receiving the first sensor signal S1, it controls the light-emitting module 14 to a second brightness. The second brightness is greater than the first brightness. In this case, the processing module 13 determines that the moving object is close enough to detect the temperature, and activates the light-emitting module 14 and controls the light-emitting module 14 to a second brightness. That is, if the processing module 13 also receives the second sensor signal S2 within a preset time interval after receiving the first sensor signal S1, it increases the brightness of the light-emitting module 14. In one embodiment, the first brightness is 50% of the maximum brightness of the light-emitting module 14, and the second brightness is the maximum brightness of the light-emitting module 14. In one embodiment, the first brightness is 30% of the maximum brightness of the light-emitting module 14, and the second brightness is 80% of the maximum brightness of the light-emitting module 14. Both the first brightness and the second brightness can be adjusted according to actual needs.

[0027] If the processing module 13 does not receive the second sensor signal S2 within a preset time interval after receiving the first sensor signal S1, it turns off the light-emitting module 14. In this case, the processing module 13 confirms that a moving object is approaching, but it is not close enough (or is not a human with body temperature), so it turns off the light-emitting module 14 to reduce power consumption.

[0028] The processing module 13 controls the light-emitting module 14 to the second brightness, and when the preset time interval has elapsed, turns off the light-emitting module 14. In this case, the processing module 13 has confirmed that the on time of the light-emitting module 14 is sufficient, so turns off the light-emitting module 14 to reduce power consumption. If the processing module 13 receives the second sensor signal S2 again within the preset time interval, the processing module 13 counts time again and recalculates the preset time interval.

[0029] In another embodiment, the processing module 13 calculates the distance between the vertex of the moving object and the first sensor module 11 based on the intensity of the first sensor signal S1 to obtain a detection distance. The processing module 13 compares the detection distance with a lookup table and adjusts the brightness of the light-emitting module 14 from the second brightness to a third brightness based on the comparison result. The lookup table records brightness levels corresponding to different detection distances. The lookup table can be obtained through prior training, and different detection distances indicate different heights of different moving objects. If the moving object is high, the brightness of the light-emitting module 14 needs to be reduced. Conversely, if the moving object is low, the brightness of the light-emitting module 14 needs to be increased to ensure a comfortable viewing experience for the moving object (e.g., a person). The lookup table can record the heights of the moving object corresponding to different detection distances and the brightness levels appropriate for the different heights. The processing module 13 can then adjust the brightness of the light-emitting module 14 to a third brightness according to the detection distance, ensuring a comfortable viewing experience for the moving object. The third brightness is greater than the first brightness, but may be smaller or greater than the second brightness. In one embodiment, the first brightness is 50% of the maximum brightness of the light emitting module 14, the second brightness is the maximum brightness of the light emitting module 14, and the third brightness is 90% of the maximum brightness of the light emitting module 14. In one embodiment, the first brightness is 30% of the maximum brightness of the light emitting module 14, the second brightness is 70% of the maximum brightness of the light emitting module 14, and the third brightness is 80% of the maximum brightness of the light emitting module 14. In one embodiment, the first brightness is 30% of the maximum brightness of the light emitting module 14, the second brightness is 80% of the maximum brightness of the light emitting module 14, and the third brightness is 70% of the maximum brightness of the light emitting module 14. The first brightness, second brightness, and third brightness can all be adjusted according to actual needs.

[0030] The above multi-stage trigger mechanism enables the sensor lighting device 1 to first turn on the light emitting module 14 after detecting a moving object, and then increase the brightness of the light emitting module 14 when it confirms the approach of the moving object. Therefore, the above multi-stage trigger mechanism can effectively prevent false triggers caused by environmental factors, and the sensor lighting device 1 can better meet the requirements of practical applications.

[0031] Furthermore, in this embodiment, the sensor illumination device 1 is equipped with a multi-stage trigger mechanism. This multi-stage trigger mechanism enables the sensor illumination device 1 to first turn on the light-emitting module 14 after detecting a moving object, and then increase the brightness of the light-emitting module 14 once it confirms the approach of the moving object. Therefore, the multi-stage trigger mechanism effectively reduces the power consumption of the sensor illumination device 1, improves the energy-saving and power-saving performance of the sensor illumination device 1, and reduces the impact on people's eyes.

[0032] In this embodiment, the sensor lighting device 1 comprises a first sensor module 11 and a second sensor module 12. The first sensor module 11 has a first sensor range, and the second sensor module 12 has a second sensor range that is smaller than the first sensor range. The first sensor module 11 is a microwave sensor, and the second sensor module 12 is a human body temperature sensor. This allows the sensor function of the sensor lighting device 1 to be unaffected by the ambient temperature, achieving higher accuracy. Furthermore, because the sensor lighting device 1 does not raise privacy concerns, its range of applications is wider and it can be used more flexibly.

[0033] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the sensor illumination device with the multi-stage trigger mechanism of this embodiment should still fall within the protection scope of the present invention.

[0034] 3 is a first explanatory diagram of a usage scenario of a sensor lighting device with a multi-stage trigger mechanism according to a second embodiment of the present invention, and also refers to FIG. 1. As shown in the figure, D1 indicates a first sensor range of the first sensor module 11, and D2 indicates a second sensor range of the second sensor module 12. When the first sensor module 11 detects a moving object TV, it generates a first sensor signal S1 and sends it to the processing module 13. After that, when the processing module 13 receives the first sensor signal S1, it performs timing, activates the light-emitting module 14, and controls the light-emitting module 14 to a first brightness.

[0035] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the sensor illumination device with the multi-stage trigger mechanism of this embodiment should still fall within the protection scope of the present invention.

[0036] 4 is a second explanatory diagram of a usage scenario of the sensor lighting device with a multi-stage trigger mechanism according to the second embodiment of the present invention, which also refers to FIG. 1. As shown in the figure, when a moving object TV approaches the second sensor module 12, the second sensor module 12 generates a second sensor signal S2. When the processing module 13 receives the second sensor signal S2 within a preset time interval after receiving the first sensor signal S1, it controls the light-emitting module 14 to a second brightness.

[0037] The above multi-stage trigger mechanism enables the sensor lighting device 1 to first turn on the light emitting module 14 after detecting a moving object, and then increase the brightness of the light emitting module 14 when it confirms the approach of the moving object. Therefore, the above multi-stage trigger mechanism can effectively prevent false triggers caused by environmental factors, and the sensor lighting device 1 can better meet the requirements of practical applications.

[0038] Furthermore, in this embodiment, the sensor illumination device 1 is equipped with a multi-stage trigger mechanism. This multi-stage trigger mechanism enables the sensor illumination device 1 to first turn on the light-emitting module 14 after detecting a moving object, and then increase the brightness of the light-emitting module 14 once it confirms the approach of the moving object. Therefore, the multi-stage trigger mechanism effectively reduces the power consumption of the sensor illumination device 1, improves the energy-saving and power-saving performance of the sensor illumination device 1, and reduces the impact on people's eyes.

[0039] In this embodiment, the sensor lighting device 1 comprises a first sensor module 11 and a second sensor module 12. The first sensor module 11 has a first sensor range, and the second sensor module 12 has a second sensor range that is smaller than the first sensor range. The first sensor module 11 is a microwave sensor, and the second sensor module 12 is a human body temperature sensor. This allows the sensor function of the sensor lighting device 1 to be unaffected by the ambient temperature, achieving higher accuracy. Furthermore, because the sensor lighting device 1 does not raise privacy concerns, its range of applications is wider and it can be used more flexibly.

[0040] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the sensor illumination device with the multi-stage trigger mechanism of this embodiment should still fall within the protection scope of the present invention.

[0041] However, conventional sensor lighting devices still have many drawbacks that need to be improved. For example, many conventional sensor lighting devices use microwave sensors, which are triggered after detecting a moving object and are prone to malfunction due to environmental factors. For example, some conventional sensor lighting devices use infrared sensors, but these sensors are easily affected by ambient temperature and have a narrow detection range. For example, some conventional sensor lighting devices use cameras, but these sensors are prone to privacy issues. In contrast, according to first and second embodiments of the present invention, a sensor lighting device includes a first sensor module, a second sensor module, a light-emitting module, and a processing module. The first sensor module has a first sensor range and generates a first sensor signal after detecting a moving object. The second sensor module has a second sensor range smaller than the first sensor range and generates a second sensor signal after detecting a moving object. The processing module is connected to the first sensor module, the second sensor module, and the light-emitting module. The processing module performs timing after receiving the first sensor signal and activates the light-emitting module to control it to a first brightness. The processing module controls the light-emitting module to a second brightness if it also receives a second sensor signal within a preset time interval after receiving the first sensor signal. The multi-stage trigger mechanism allows the sensor-based lighting device to first turn on the light-emitting module after detecting a moving object, and then increase the brightness of the light-emitting module once it confirms the approach of the moving object. Therefore, the multi-stage trigger mechanism effectively prevents false triggers caused by environmental factors, allowing the sensor-based lighting device to better meet the requirements of practical applications.

[0042] Furthermore, according to the first and second embodiments of the present invention, the sensor lighting device has a multi-stage trigger mechanism. This multi-stage trigger mechanism enables the sensor lighting device to first turn on the light-emitting module after detecting a moving object, and then increase the brightness of the light-emitting module once it confirms the approach of the moving object. Therefore, the multi-stage trigger mechanism effectively reduces the power consumption of the sensor lighting device, improves the energy-saving and power-saving performance of the sensor lighting device, and reduces the impact on people's eyes.

[0043] Furthermore, according to the first and second embodiments of the present invention, the sensor illumination device comprises a first sensor module and a second sensor module. The first sensor module has a first sensor range, and the second sensor module has a second sensor range that is smaller than the first sensor range. The first sensor module is a microwave sensor, and the second sensor module is a human body temperature sensor. This makes the sensor function of the sensor illumination device unaffected by the ambient temperature, achieving higher accuracy.

[0044] Furthermore, according to the first and second embodiments of the present invention, the multi-stage trigger mechanism of the sensor illumination device can be realized without using a camera.

[0045] Furthermore, according to the first and second embodiments of the present invention, the design of the sensor lighting device is simple, so that the desired effect can be achieved without significantly increasing costs. Therefore, the sensor lighting device has high practicality and can meet the requirements of various applications. As can be seen from the above, the sensor lighting device with the multi-stage trigger mechanism according to the embodiments of the present invention can indeed achieve very good technical effects.

[0046] 5 is a flowchart of a control method for a sensor illumination device having a multi-stage trigger mechanism according to a third embodiment of the present invention. As shown in the figure, the control method for a sensor illumination device according to this embodiment includes the following steps: Step S51: When the processing module performs timing after receiving a first sensor signal generated by a first sensor module having a first sensor range detecting a moving object, the processing module activates the light-emitting module and controls the light-emitting module to a first brightness. Step S52: When the processing module receives a second sensor signal generated by a second sensor module having a second sensor range smaller than the first sensor range and detecting a moving object within a preset time interval after receiving the first sensor signal, the processing module controls the light-emitting module to a second brightness. Step S53: Turn off the light-emitting module if the processing module does not receive the second sensor signal within a preset time interval after receiving the first sensor signal. Step S54: The processing module controls the light-emitting module to a second brightness and turns off the light-emitting module after a preset time interval has elapsed.

[0047] In another embodiment, the control method further includes the steps of: calculating, by the processing module, a distance between the vertex of the moving object and the first sensor module based on the intensity of the first sensor signal to obtain a detection distance; and comparing, by the processing module, the detection distance with a lookup table; and adjusting, based on the comparison result, the brightness of the light-emitting module from the second brightness to a third brightness, wherein the lookup table records the brightness corresponding to different detection distances.
