Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular to a low-power lighting system and a control method. Background Art

[0002] Rhythmic lighting is a hot topic in the current lighting research field. By controlling the illumination and color temperature of the light, the light is made to conform to the human body rhythm, which inhibits the secretion of melatonin during the day, keeps people excited and awake, and thus helps to improve work and study results and efficiency. Conversely, it promotes the secretion of melatonin at night, making it easier for people to fall asleep and improve sleep quality.

[0003] To achieve rhythmic lighting, it is usually necessary to configure a rhythmic lighting system, which includes a photoelectric sensor for detecting ambient light and a central controller. The central controller controls the color temperature and illumination of the light according to the information detected by the photoelectric sensor to make the light meet the requirements of rhythmic lighting.

[0004] Although the current rhythmic lighting system can provide rhythmic lighting, it also introduces new technical problems. That is, the rhythmic lighting system needs to continuously monitor the changes in ambient light, that is, the photoelectric sensor is continuously in working condition, and the photoelectric sensor is usually powered by a battery. Users need to replace the battery frequently, which leads to a relatively poor user experience; in addition, the current rhythmic lighting system, because the system needs to keep running continuously, leads to higher energy consumption.

[0005] How to reduce the energy consumption of rhythmic lighting systems, reduce the frequency of sensor battery replacement and optimize user experience is a technical problem that needs to be solved urgently in this field. Summary of the invention

[0006] The purpose of the present invention is to provide a low-power lighting system and a lighting control method. Through the cooperation of a radar module and an ambient light sensing module, when there is no one in the environment, only the radar module in the entire lighting system works, and the rest of the system does not work, thereby reducing the energy consumption of the lighting system.

[0008] Furthermore, after the ambient light sensing module detects ambient light in the environment and sends the detection result to the sensor control chip, the sensor control chip disconnects the circuit of the ambient light sensing module.

[0009] Optionally, the ambient light sensing module detects the color temperature value and / or illumination value of the environment.

[0010] Furthermore, the radar module scans the environment for human body information at a first time interval.

[0011] Furthermore, it also includes a wired control module, which is connected to the wired transmission module. When the application controller receives a control signal from the wired control module, the application controller controls the DALI lamp to work according to the control signal.

[0012] The present invention also provides a low-power lighting control method applied to the low-power lighting system, comprising the following steps: The radar module detects a human body signal, and when the radar module detects a human body signal, the radar module sends the human body signal to the sensor control chip; The sensor control chip controls the circuit of the ambient light sensing module to close, the ambient light sensing module detects the ambient light, and sends the detection information to the sensor control chip, and the sensor control chip sends the detection information to the application controller; The application controller compares the preset information with the detection information, and sends a control signal to the DALI lamp to control the operation of the DALI lamp when the detection information does not meet the preset information.

[0013] Furthermore, when the sensor control chip receives the detection information from the ambient light sensing module, it controls the circuit of the ambient light sensing module to be disconnected.

[0014] Furthermore, the radar module detects human body signals at a first time interval.

[0015] Furthermore, after the radar module sends the human body signal to the sensor control chip, the sensor control chip controls the radar module to cut off power.

[0016] Furthermore, the detection information includes a color temperature value and / or an illumination value of the environment.

[0017] The present invention provides a low-power lighting system and lighting control method.

[0018] When there is no one in the environment, the ambient light sensing module of the rhythm sensor in this system is always in a power-off state, which can save power to a great extent, reduce the frequency of sensor battery replacement, and optimize the user experience.

[0028] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0029] The present invention provides a low-power lighting system to solve the problems of high energy consumption, high replacement frequency of photoelectric sensor batteries, and poor user experience in the current rhythmic lighting system. Figure 1 As shown, the system includes: An application controller, the application controller comprising a wired transmission module and a wireless transmission module; A DALI lamp, which is connected to the wired transmission module and receives a control signal from the application controller to operate; A rhythm sensor, wherein the rhythm sensor establishes communication with the wireless transmission module, and the rhythm sensor comprises a radar module, an ambient light sensing module 4 and a sensor control chip 1; The radar module 3 scans the environment for human body information and sends the scanning result to the sensor control chip 1. The sensor control chip 1 controls the opening and closing of the circuit of the ambient light sensing module 4 according to the scanning result; the ambient light sensing module 4 detects the ambient light of the environment and sends the detection result to the sensor control chip 1. The sensor control chip 1 sends the received information to the application controller. The application controller sends a control signal to the DALI lamp according to the received information; the ambient light sensing module 4 detects the color temperature value and / or illumination value of the environment.

[0030] like Figure 2As shown, the rhythm sensor of the present invention includes a power supply 2, which is used to power the sensor; a sensor control chip 1, which is connected to the power supply 2, and the sensor control chip 1 is also connected to a radar module 3, an ambient light sensing module 4 and a wireless module 5; the radar module 3 scans the environment for human body information, and sends the scanning result to the sensor control chip 1, and the sensor control chip 1 controls the opening and closing of the circuit of the ambient light sensing module 4 according to the scanning result; the ambient light sensing module 4 detects the ambient light of the environment, and sends the detection result to the sensor control chip 1, and the sensor control chip 1 sends the detection result through the wireless module 5. In this embodiment, the wireless module 5 is a Bluetooth module or a radio frequency module, preferably a Bluetooth module; the ambient light sensing module 4 detects the color temperature value and / or illumination value of the environment. The sensor control chip 1 adopts the TLSR8250 chip, the radar module 3 is a BGT24L radar sensor, and the ambient light sensing module 4 is an STK2236 photoelectric sensor.

[0031] In the rhythmic lighting system provided in this embodiment, the radar module 3 first scans the environment for human information, and the sensor control chip 1 controls the opening and closing of the circuit of the ambient light sensing module 4 according to the scanning results; when the radar module 3 does not scan the human information, the sensor control chip 1 controls the circuit of the ambient light sensing module to be disconnected. It should be noted here that when the radar module 3 does not scan the human information, the ambient light sensing module 4 may be in two states; the first state is that its circuit is originally in an open circuit state, at which time the sensor control chip 1 maintains the circuit of the ambient light sensing module 4 open circuit after receiving the scanning information; the second state is that its circuit is originally in a closed state, at which time the sensor control chip 1 controls the circuit of the ambient light sensing module 4 to switch from the open state to the open circuit state.

[0032] The application controller sends a control signal to the DALI lamp according to the received information. In this embodiment, if there is someone in the environment, the information received by the sensor control chip 1 includes the scanning result of the radar module 3 and the detection result of the ambient light sensing module 4. At this time, the application controller controls the DALI lamp to turn on. If the DALI lamp has been turned on before, the application controller keeps the DALI lamp turned on; if there is no one in the environment, the information received by the sensor control chip 1 only includes the scanning result of the radar module 3. At this time, the application controller does not turn on the DALI lamp. If the DALI lamp has been turned on before, the application controller controls the DALI lamp to turn off.

[0033] In this embodiment, through the cooperation between the radar module 3 and the ambient light sensing module 4, when there is no one in the environment, only the radar module 3 in the entire lighting system works, and the rest of the system does not work, thereby reducing the energy consumption of the lighting system.

[0034] Furthermore, the rhythm sensor of this embodiment also uses a battery as a power source 2. Only after the radar module 3 senses human body information will the sensor control chip 1 control the circuit of the ambient light sensing module 4 to close, and the ambient light sensing module 4 will be in a power consumption state; when the radar module 3 does not recognize human body information, the ambient light sensing module 4 is in a power-off state, and when the radar module 3 does not scan human body information during the next human body information scan, the sensor control chip 1 will control the circuit of the ambient light sensing module 4 to disconnect. That is, when the rhythm sensor of this embodiment is in an environment where there is no one, the ambient light sensing module 4 is always in a power-off state, which can save a lot of electricity. After testing, the rhythm sensor in this embodiment can extend the single working time from the original 3-5 days to 20-40 days.

[0035] Furthermore, the radar module 3 performs a human body information scan on the environment at a first time interval. In this embodiment, the sensor control chip 1 has a built-in timer, and the timer sends a first time signal to the sensor control chip 1 at a time interval. The sensor control chip 1 controls the circuit conduction of the radar module 3 according to the first time signal to perform human body information scanning. By setting the radar module 3 to an intermittent working mode, the power consumption of the radar module 3 is further reduced. In this embodiment, the first time interval is 2-20 seconds.

[0036] In this embodiment, after receiving the scanning result, the sensor control chip 1 controls the circuit of the radar module 3 to be disconnected. That is, the radar module also works intermittently, which can further extend the single working time of the rhythm sensor to 3-5 months, reducing the replacement frequency of the rhythm sensor battery.

[0037] According to an embodiment of the present invention, after the ambient light sensing module 4 detects ambient light in the environment and sends the detection result to the sensor control chip 1, the sensor control chip 1 disconnects the circuit of the ambient light sensing module 4. In order to further reduce the replacement frequency of the rhythm sensor battery, the ambient light sensing module 4 also works in an intermittent manner, and its power consumption can be controlled at a low level even when there are people in the environment.

[0038] Furthermore, the low-power lighting system also includes a wired control module, which is connected to the wired transmission module. When the application controller receives a control signal from the wired control module, the application controller controls the DALI lamp to work according to the control signal. For the rhythmic lighting system, during the day, due to sufficient light, the ambient light usually meets the requirements of rhythmic lighting, so its working time is usually one hour before sunset to one hour after sunrise. Therefore, in order to ensure the availability of the system during the day, the system is also equipped with a wired control module, and the user can also control the system through the wired control module during the day.

[0039] According to an embodiment of the present invention, the present invention also provides a low power consumption lighting control method, such as Figure 3 As shown, the following steps are included: The radar module 3 detects human body signals, and when the radar module 3 detects human body signals, the radar module 3 sends the human body signals to the sensor control chip 1; The sensor control chip 1 controls the circuit of the ambient light sensing module 4 to close, the ambient light sensing module 4 detects the ambient light, and sends the detection information to the sensor control chip 1, and the sensor control chip 1 sends the detection information to the application controller; The application controller compares the preset information with the detection information, and sends a control signal to the DALI lamp to control the operation of the DALI lamp when the detection information does not meet the preset information.

[0040] The method further comprises the steps of: The radar module 3 detects a human body signal, when the radar module 3 does not detect a human body signal; Sending the blank signal to the sensor control chip 1; The sensor control chip 1 sends the signal to the application controller; The application controller queries the state of the current DALI lamp, and if the DALI lamp is in the on state, turns off the lamp, and if the DALI lamp is in the off state, keeps it on.

[0041] In this embodiment, the detection information includes the color temperature value and / or the illuminance value of the environment, and the preset information is also the color temperature value and / or the illuminance value, corresponding to the detection information.

[0042] In the case where the detection information is different from the preset information, the application controller controls the color temperature value and / or the illumination value of the DALI lamp to make the detection information the same as the preset information.

[0043] In this embodiment, when the sensor control chip 1 receives the detection information from the ambient light sensing module 4, it controls the circuit of the ambient light sensing module 4 to be disconnected. The radar module 3 detects human body signals at a first time interval. When the radar module 3 sends the human body signal to the sensor control chip 1, the sensor control chip 1 controls the radar module 3 to be powered off.

[0044] In the description of the specification, the description with reference to the terms "one embodiment", "some embodiments", "an embodiment", "some embodiments", "an example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
