Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular to a lamp system. Background Art

[0002] With the development of the times, people's demand for lighting is getting higher and higher. Lamps that need to be manually operated can no longer meet people's needs. As a result, more and more lamps with various functions have emerged on the market, such as voice-controlled lamps, light-controlled lamps, infrared sensor lamps, etc. These lamps can meet different application scenarios to a certain extent.

[0003] Smart lamps have been gradually popularized in the market. These lamps have more functions, and many smart lamps include one or more functions of the above lamps. Some smart lamps are equipped with cameras, which can determine the user's position or status by acquiring images in the environment, and can provide automatic switching services based on the user's position, posture, gestures, etc.

[0004] Although the smart lamps currently on the market can usually provide reasonable lighting services for a person in a room, there is still a lack of smart lamps on the market that can provide lighting more reasonably for environments such as corridors. Summary of the invention

[0006] Exemplarily, the first controller is also used to: after the lighting component of the second lamp is illuminated, when it is determined that a person is present based on the personnel situation information detected by the radar component of the second lamp, control the lighting component of the third lamp located downstream of the second lamp on the daily activity path to illuminate, and control the lighting component of the first lamp to extinguish.

[0007] Exemplarily, the lighting system includes at least three lamps for providing lighting for the same daily activity path, and the first controller is also used to control all lighting components of the daily activity path to emit light when the personnel situation information detected by the radar components of the first lamp and the second lamp determine the presence of personnel in turn.

[0008] Exemplarily, multiple lamps are used to provide lighting for multiple daily activity paths, the first lamp and the second lamp are used to provide lighting for a first daily activity path among the multiple daily activity paths, the first lamp and the fourth lamp are used to provide lighting for a second daily activity path among the multiple daily activity paths, and the first controller is also used to control the lighting component of the fourth lamp to emit light when it is determined that a person appears based on the personnel situation information detected by the radar component of the first lamp and that the person is heading towards the second daily activity path.

[0009] Exemplarily, the first controller is used to: determine the order in which people pass through the multiple lamps based on personnel situation information detected by radar components of the multiple lamps when the multiple lamps are used for the first time; and determine the daily activity path based on the order.

[0010] Exemplarily, the first controller includes multiple sub-first controllers, which are arranged in a one-to-one correspondence in multiple lamps, and each sub-first controller is used to control the on / off of the lighting component of the corresponding lamp; each lamp includes a communication module, and the first controller of each lamp communicates with the communication modules of other lamps via the communication module of the corresponding lamp, wherein the sub-first controller is used to: when multiple lamps are used for the first time, based on the personnel situation information detected by the radar components of the multiple lamps, determine that the lamp that first detects a person is the first lamp, and the sub-controller of the first lamp sends a first signal to other lamps among the multiple lamps via the communication module; the lamp that receives the first signal among the multiple lamps and detects a person after receiving the first signal is determined to be the second lamp, and the sub-controller of the second lamp sends a second signal to other lamps among the multiple lamps via the communication module.

[0011] Exemplarily, one of the multiple lamps is an initiator for building a local area network when the multiple lamps are used for the first time. The initiator is a lamp among the multiple lamps whose sub-controller first determines that a person is present based on personnel situation information detected by its radar component. The initiator's sub-controller is used to: send a connection request signal to other lamps among the multiple lamps via a communication module; and establish a communication connection with the other lamps based on a connection response signal from the other lamps, wherein the connection response signal from the other lamps is sent when the lamp determines that a person is present based on the personnel situation information detected by its radar component.

[0013] Exemplarily, when determining that a vital sign is abnormal, the first controller is also used to: control the lighting of lamps from the first lamp to the fifth lamp on the daily activity path, where the fifth lamp is a lamp that determines that a vital sign is abnormal based on personnel situation information detected by its radar component.

[0014] The third aspect of the present application provides a lighting system, comprising: a plurality of lamps, the plurality of lamps being used to sequentially provide lighting for people's daily activity paths, each lamp comprising a lighting component and a radar component, the radar component being used to detect personnel situation information within at least a portion of the lighting range of the corresponding lighting component; and a second controller, the second controller being communicatively connected to the radar components of the plurality of lamps for receiving personnel situation information, the second controller being electrically connected to the lighting components of the plurality of lamps for controlling the on / off of the lighting components, wherein the second controller is specifically used to: when it is determined that there is an abnormality in the personnel situation information, control the lighting component of at least one lamp among the plurality of lamps that is closest to the person to issue a light alarm.

[0015] Exemplarily, when determining that the personnel situation information is abnormal, the second controller is also used to: control the lighting of multiple lamps from the first lamp on the daily activity path to the lamp with abnormal personnel situation information detected by the radar component, where the first lamp is the first lamp on the daily activity path.

DETAILED DESCRIPTION

[0030] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0031] In order to fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0032] The embodiment of the present invention provides a lamp system. The lamp system can be applied to living places such as nursing homes, hospital inpatient departments, dormitories, and corridors outside rooms. The lamp according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] According to one aspect of the present application, a lighting system is provided. The lighting system includes a plurality of lighting fixtures, and the plurality of lighting fixtures are used to sequentially provide lighting for the daily activity paths of people. The daily activity paths of people include environments such as corridors and hallways that restrict people's walking, rather than environments such as squares where people can walk in any area. Therefore, people walking along the daily activity paths can only walk from one lamp to an adjacent lamp in sequence, and cannot directly reach other lamps from one lamp over an adjacent lamp. Figure 1 As shown, each lamp includes a lighting assembly 100 and a radar assembly 200, and the radar assembly 200 is used to detect the personnel situation information within at least part of the lighting range of the corresponding lighting assembly 100. The lighting assembly 100 may include a light source such as a fluorescent lamp, an LED lamp, etc. In some embodiments, a light-diffusing plate is provided on the surface of some lamp beads to make the light softer. In the embodiments mentioned below, each lamp may include a lamp with a light-diffusing plate and a spotlight with concentrated light, which can provide extensive lighting indoors or provide lighting for designated areas indoors.

[0034] The radar component 200 is used to detect the personnel situation information of the personnel in the living environment, and the personnel situation information includes information about the number of personnel and personnel activities. The radar component 200 may include one or more radar sensors such as millimeter wave radar, microwave radar, ultrasonic radar, infrared radar, laser radar, etc. Taking the radar component 200 using millimeter wave radar as an example, the wavelength of the millimeter wave used is between microwave and centimeter wave, so the millimeter wave radar has some advantages of microwave radar and photoelectric radar. On the whole, the millimeter wave radar can detect the number of people, as well as the movement of people. For each person, the millimeter wave radar can detect the tiny activities of the person's body, such as breathing, heartbeat, etc., so as to determine the physical state of the person. In some embodiments, the millimeter wave radar can also obtain information such as the gestures of the person and the placement of objects in the environment where the person is located. The use of millimeter wave radar can avoid the privacy issues caused by the use of cameras, and has high detection accuracy and a wide range of uses.

[0035] The lamp system also includes a first controller 800, which is communicatively connected to the radar components 200 of the plurality of lamps for receiving personnel situation information. The first controller 800 is electrically connected to the lighting components 100 of the plurality of lamps for controlling the on / off of the lighting components 100. The first controller 800 of the lamp system may also be the same as the first controller 800 of the lamp mentioned above.

[0036] The control device can be constructed using electronic components such as timers, comparators, registers, digital logic circuits, etc., or can be implemented using processor chips such as single-chip microcomputers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic arrays (PLA), application-specific integrated circuits (ASICs), and their peripheral circuits. In some embodiments, the first controller 300 may include circuit elements arranged in each lamp. In other embodiments, the first controller 300 may be centrally arranged at a suitable location in each room and corridor to receive information obtained by the radar component 200 of each lamp and control the lighting component 100 of the lamp accordingly. Optionally, the first controller 300 may be arranged in a distribution box and electrically connected to the lamps in one or more rooms and corridors. Optionally, the first controller 300 may also be a device similar to a smart speaker, electrically connected to each lamp through wireless communication, thereby receiving information obtained by the radar component 200 of the lamp and controlling the lighting component 100 accordingly.

[0037] The first controller 800 is specifically used to control the lighting assembly 100 of the first lamp 500 to emit light when it is determined that a person appears based on the personnel situation information detected by the radar assembly 200 of the first lamp 500 on the daily activity path. The first lamp 500 can be a lamp at the entrance and exit of the corridor, and the person can only enter the corridor from the corridor entrance or leave the corridor from the corridor entrance and exit. Taking the person entering the corridor as an example, the first lamp 500 detects the presence of the person and can provide lighting for the person. Since the corridor restricts the walking direction and route of the person, after the first predetermined time interval, the first controller 800 can control the lighting assembly 100 of the second lamp 600 located downstream of the first lamp 500 on the daily activity path to emit light. Thus, before the person arrives at the second lamp 600, the second lamp 600 has provided lighting for the person in the area. In the case where there is no gap between the lighting areas of the two lamps, there is almost no lighting blind spot on the route where the person walks. The first predetermined time can be determined according to the walking speed of the person and the distance between the first lamp 500 and the second lamp 600. In some embodiments, the first preset time can be very short, so as to illuminate the path where people walk in advance and provide a better experience. After the second preset time interval, when it is determined that no people appear based on the personnel situation information detected by the radar component 200 of the second lamp 600, the lighting component 100 of the second lamp 600 is controlled to be extinguished. Thus, when a person stays in a certain area, the downstream lamps will not be lit all the time. The second preset time can also be determined based on the walking speed of the person and the distance between the first lamp 500 and the second lamp 600. Optionally, the second preset time can be the time for a normal person to enter the detection range of the first lamp 500 and walk to the detection range of the second lamp 600, or it can be longer than this time so as to be suitable for elderly people with slower walking speeds.

[0038] In some embodiments, the daily activity path can extend into the room. For example, the first lamp 500 is set outside the door of the room, and the second lamp 600 is set inside the room. As a result, lighting can be provided indoors before a person enters the room, without manual operation. The first lamp 500 and the second lamp 600 may also be set in multiple rooms. After a person enters the room where the first lamp 500 is set, the first lamp 500 is lit, and the second lamp 600 is also lit. In the case where a person stays in the room where the first lamp 500 is set, the second lamp 600 can turn off by itself without detecting the person's entry, so as to save energy and extend the service life of the lighting assembly 100.

[0039] Exemplarily, the first controller 800 is also used to control the lighting assembly 100 of the third lamp 700 located downstream of the second lamp 600 on the daily activity path to light up, and control the lighting assembly 100 of the first lamp 500 to turn off, when it is determined that a person appears based on the personnel situation information detected by the radar assembly 200 of the second lamp 600 after the lighting assembly 100 of the second lamp 600 lights up. In the case where more lamps are set in the corridor, when a person walks in one direction, he will pass the first lamp 500, the second lamp 600 and the third lamp 700 in sequence. Therefore, when it is confirmed that the person walks to the second lamp 600, the lighting assembly 100 of the third lamp 700 in front of the person can be controlled to light up, and the lighting assembly 100 of the first lamp 500 behind the person can be turned off. In this way, the service life of the lamp lighting assembly 100 can be extended and electric energy can be saved.

[0040] In some embodiments, multiple third lamps 700 may be provided on the forked roads. When a person passes the second lamp 600 at the forked road, both third lamps 700 may be lit after a first preset time. Then, when the person enters one of the forked roads and arrives under the third lamp 700 of the forked road, the third lamp 700 of the other forked road automatically turns off after no object is detected and the duration reaches a second preset time interval.

[0041] Exemplarily, the lighting system may include at least three lamps for providing lighting for the same daily activity path. The first controller 800 is also used to control all lighting components 100 in the daily activity path to emit light when the personnel situation information detected by the radar component 200 of the first lamp 500 and the second lamp 600 determines that there are people appearing in sequence. Taking a corridor as an example, when a person passes through the first lamp 500 and the second lamp 600 in succession, it can be confirmed that the person is walking in the direction of the corridor. The first controller 800 controls all lighting components 100 in the daily activity path to emit light, which can provide a better field of vision for the personnel, and the control logic is simpler. When a fork in the road appears, the direction of the fork in the road that the person is heading to can be determined by the lamp number that the person passes by, and all lighting components 100 on the fork in the road can be controlled to emit light.

[0042] Exemplarily, a plurality of lamps are used to provide lighting for a plurality of daily activity paths, the first lamp 500 and the second lamp 600 are used to provide lighting for a first daily activity path among the plurality of daily activity paths, and the first lamp 500 and the fourth lamp are used to provide lighting for a second daily activity path among the plurality of daily activity paths. The first controller 800 is also used to control the lighting assembly 100 of the fourth lamp to emit light when determining that a person appears and that the person is heading toward the second daily activity path based on the personnel situation information detected by the radar assembly 200 of the first lamp 500. In some embodiments, the radar assembly 200 can determine the direction in which the person is moving. When the positions of the third lamp 700 and the fourth lamp are determined according to the walking direction of the passing person, the first controller 800 can determine whether the user is walking toward the first daily activity path or the second daily activity path. Thus, the lamp system can control the lamps on the path to which the user is heading to light up in advance, thereby improving the user experience.

[0043] Exemplarily, the first controller 800 is used to determine the order in which people pass through the multiple lamps based on the personnel situation information detected by the radar components 200 of the multiple lamps when the multiple lamps are used for the first time, and to determine the daily activity path based on the order. Specifically, when a person passes by the first lamp 500, the first controller 800 can determine the sequence number of the radar component 200 of the first lamp 500 as 1, and when a person passes by the second lamp 600, the first controller 800 can determine the sequence number of the radar component 200 of the second lamp 600 as 2, and so on. In some embodiments, in addition to determining the sequence of multiple lamps when used for the first time, the sequence can also be modified when the daily activity path changes during use.

[0044] like Figure 2A As shown, in some exemplary embodiments, the first controller 800 may be configured as a centralized controller, and the first lamp 500, the second lamp 600, and the third lamp 700 are all electrically connected to the first controller 800. Figure 2B As shown, exemplarily, the first controller 800 may include a plurality of sub-controllers, which are arranged in a plurality of lamps one by one, and each sub-controller is used to control the on / off of the lighting assembly 100 of the corresponding lamp. Each lamp may include a communication module, and the controller of each lamp communicates with the communication modules of other lamps via the communication module of the corresponding lamp. The sub-controller may be integrated with the circuit board of one or more of the radar assembly 200, the lighting assembly 100, and the power supply assembly. Figure 4As shown, the sub-controller is used to determine that the lamp that first detects a person is the first lamp 500 based on the personnel situation information detected by the radar assembly 200 of the multiple lamps when the multiple lamps are used for the first time, and the sub-controller 510 of the first lamp 500 sends a first signal to other lamps in the multiple lamps via the communication module; the lamp that receives the first signal among the multiple lamps and detects a person after receiving the first signal is determined to be the second lamp 600, and the sub-controller 610 of the second lamp 600 sends a second signal to other lamps in the multiple lamps via the communication module. In an embodiment in which more lamps are provided, the third lamp can be determined in the same way as the second lamp, and the same is true for the fourth, fifth, and even Nth lamps. In this way, the order of lamps in the daily activity path can be determined. Each lamp has an independent sub-controller, and there is no need to set up a centralized first controller 800, and the layout of the line is also simpler. Specifically, all lamps can be connected only to power lines, without the need to establish electrical connections between the lighting assembly 100 and the radar assembly 200 of each lamp and the centralized first controller 800 in a wired or wireless manner. Figure 2B In the illustrated embodiment, the lamp system further includes a third lamp 700 and a sub-controller 710 of the third lamp 700 which is integrated in the third lamp 700 .

[0045] Combined with reference Figure 2C and Figure 2D , when a person reaches the detection range of the radar assembly 200 of the first lamp 500, the sub-controller 510 of the first lamp 500 controls the lighting assembly 100 to emit light, and sends a signal to the second lamp 600 through the communication module after a first preset time interval. The sub-controller 610 of the second lamp 600 receives the signal of the first lamp 500 via the communication module and controls the lighting assembly 100 to emit light. When a person reaches the detection range of the radar assembly 200 of the second lamp 600, the sub-controller 610 of the second lamp 600 sends a signal to the first lamp 500 via the communication module, and sends a signal to the third lamp 700 via the communication module after a first preset time interval. The sub-controller 510 of the first lamp 500 receives the signal of the second lamp 600 via the communication module and controls the lighting assembly 100 to turn off. The sub-controller 710 of the third lamp 700 receives the signal of the second lamp 600 via the communication module and controls the lighting assembly 100 to emit light.

[0046] Exemplarily, one of the multiple lamps is an initiator for building a local area network when the multiple lamps are used for the first time. The initiator is the lamp whose sub-controller first determines that a person is present based on the personnel situation information detected by its radar component 200. The initiator's sub-controller is used to send a connection request signal to other lamps in the multiple lamps via a communication module. The initiator's sub-controller is also used to establish a communication connection with other lamps based on a connection response signal from other lamps. Taking WIFI communication as an example, multiple sub-controllers need to handshake to communicate with each other via a communication component. When the lamps leave the factory, all default configurations can be used. After the multiple lamps are installed, at least one lamp's sub-controller needs to send a connection request signal via the communication component. After receiving the connection request signal via the communication component, the sub-controllers of other lamps can send a connection response signal when the lamp determines that a person is present based on the personnel situation information detected by its radar component 200. In actual use, there is almost no situation where there are people under multiple lamps at the same time. Therefore, when someone passes by a lamp, the lamp can respond to the connection request signal, add itself to the local area network, and thus establish a connection with other lamps. Optionally, if there are too many lamps connected to the initiator's sub-controller, the initiator's sub-controller can communicate with the sub-controllers of other lamps and transfer the connections of some lamps to the sub-controller of this lamp. Optionally, in the case that some lamps are too far away from the initiator's sub-controller, the initiator's sub-controller can connect a sub-controller of a lamp between itself and the target lamp as a relay. The sub-controller acting as a relay can be selected according to the strength of the signal.

[0047] Exemplarily, the personnel situation information includes information about vital signs, and the first controller 800 is further used to: based on the personnel situation information detected by the radar assembly 200 of any of the multiple lamps, when it is determined that the vital signs are abnormal, control the lighting assembly 100 of at least one of the multiple lamps to issue a light alarm. In this way, the alarm function can be achieved without the need for an additional alarm mechanism, and the alarm will not emit an alarm sound that disturbs other personnel.

[0048] Exemplarily, when determining that the vital signs are abnormal, the first controller 800 is also used to control the lighting of the lamps from the first lamp 500 to the fifth lamp on the daily activity path, and the fifth lamp is a lamp that determines that the vital signs are abnormal based on the personnel situation information detected by its radar component 200. Thus, when there are abnormal vital signs of people in any room, the lamps in the corridor can guide medical personnel or treatment personnel to the corresponding room. In some embodiments, the corridor may have windows, and natural light may enter. The continuous lighting of the lamps in the corridor may not be enough to attract attention. Therefore, the lighting of the lamps from the first lamp 500 to the fifth lamp may include controlling them to emit light in a flashing manner, or to emit light in different colors.

[0049] Another aspect of the present application also provides a lamp system. The lamp system includes a plurality of lamps, and the plurality of lamps are used to sequentially provide lighting for the daily activity path of personnel. Each lamp includes a lighting assembly 100 and a radar assembly 200, and the radar assembly 200 is used to detect the personnel situation information within at least a part of the lighting range of the corresponding lighting assembly 100. Each lamp also includes a second controller, and the second controller is connected to the radar assembly 200 of the plurality of lamps in communication, and is used to receive the personnel situation information. The second controller is electrically connected to the lighting assembly 100 of the plurality of lamps, and is used to control the on / off of the lighting assembly 100. Among them, the second controller is specifically used to control the lighting assembly 100 of at least one lamp closest to the personnel among the plurality of lamps to issue a light alarm when it is determined that there is an abnormality in the personnel situation information. The abnormality in the personnel situation information includes but is not limited to abnormal breathing of the personnel, abnormal heartbeat of the personnel, and falling of the personnel. By issuing a light alarm, relevant personnel can be reminded to provide timely assistance, and the structure of the lamp is simple, and no sound will be emitted to cause panic among irrelevant personnel.

[0050] Exemplarily, when determining that the personnel situation information is abnormal, the second controller is also used to control the lighting of multiple lamps on the daily activity path from the first lamp to the lamp with abnormal personnel situation information detected by the radar component 200, where the first lamp is the first lamp on the daily activity path. The serial number of the lamp can be marked on the surface of the lamp when it leaves the factory, or it can be automatically obtained through machine learning after the installation is completed, as with the lamp system mentioned above. Therefore, when a person is abnormal, the lamp can form a guide on the daily activity path, thereby helping relevant personnel to quickly arrive at the scene for rescue or disposal.

[0051] Exemplarily, the radar assembly 200 is also used to obtain the heartbeat information of the person. The second controller determines that the person's condition information is abnormal based on the heartbeat information. For the radar assembly 200 using millimeter wave radar, the heartbeat information of the person can be obtained based on the vibration of the person's body detected. In this way, when the heartbeat of the person is abnormal, such as myocardial infarction that the elderly are prone to, the lighting assembly 100 of the lamp can be controlled in time to issue an alarm prompt so that the person can receive timely assistance.

[0052] Exemplarily, the radar assembly 200 is also used to obtain breathing information of the personnel, and the second controller determines that there is an abnormality in the personnel condition information based on the breathing information. For the radar assembly 200 using millimeter wave radar, the breathing information of the personnel can also be obtained based on the detected vibration of the personnel's body. Thus, in the event of suffocation of the personnel, the second controller can also promptly control the lighting assembly 100 of the lamp to issue an alarm prompt so that the personnel can obtain timely assistance. The embodiments of the present application do not exclude embodiments that simultaneously detect the user's heartbeat information and breathing information.

[0053] Exemplarily, the radar assembly 200 is also used to obtain the height information of the personnel, and the second controller determines that the personnel situation information is abnormal based on the posture information and the height information. In view of the easy fall of the elderly, the radar assembly 200 can determine whether the personnel sits down, lies down or falls down by obtaining the height information of the personnel. Optionally, according to the rate of change of the personnel's height, when the rate of change of the personnel's height is too fast, the second controller can judge that the personnel falls down. Optionally, the radar assembly 200 can obtain the posture information of the personnel, and when the posture of the personnel is consistent with the posture after falling down, the second controller judges that the personnel falls down, rather than sitting down or lying down. Optionally, the second controller can judge whether the personnel falls down based on the height information and the posture information, so that it is not easy to cause false alarms or missed alarms. Thus, in the case of a person falling down, an alarm can be promptly called to call other personnel for disposal.

[0054] like Figure 4 As shown, in an exemplary embodiment, the second controller determines the personnel situation information through the radar assembly 200. When the personnel situation information is normal, the lighting assembly is controlled to emit light normally. When the personnel situation information is abnormal, all lamps from the first lamp to the lamp closest to the person are determined, and the lighting assemblies of the above lamps are controlled to emit light in an alarm mode. Thus, a guiding path is formed to guide other personnel to accurately reach the position of the abnormal person.
