Description

Technical Field

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

[0002] With the development and improvement of people's living standards, higher requirements are put forward for travel. Today, with the continuous development of the rail transit network, the number of passengers traveling by high-speed rail or bullet train is increasing year by year. During the process of taking rail transit, passengers generally have higher requirements for the conditions of the passenger compartments in the train. In order to improve the experience of passengers during the journey, especially in the sleeper compartments where passengers spend a long time and need to sleep, the application of smart home technology is particularly suitable.

[0003] As an essential part of the passenger compartment, the intelligentization of the lighting system can significantly improve the experience of passengers taking rail transit. Traditional lighting appliances for train compartments usually adopt simple induction adjustment, timing adjustment or manual adjustment methods. The lighting equipment has a single function and less induction information, and cannot meet the various brightness adjustment requirements of passengers in the compartment, especially during the evening period. Summary of the Invention

[0004] In order to at least partially solve the problems existing in the prior art, some embodiments of the present invention provide a lighting fixture system, including: a lighting component for a room where a predetermined number of people rest. The lighting component includes a radar for detecting the situation information of the people in the room, and the situation information includes vital sign information and the number of people information; and a controller for controlling the lighting component in a first manner, and the first manner includes: based on the vital sign information, determining whether the vital signs of the people in the room are abnormal; when the vital signs of any person in the room are abnormal, controlling the lighting component to work in an alarm mode; when the vital signs of all the people in the room are normal, based on the number of people information, determining whether the current number of people in the room is greater than the predetermined number; when the current number of people is greater than the predetermined number, controlling the lighting component to work in a lighting mode; when the current number of people is less than or equal to the predetermined number, based on the vital sign information, determining whether the people in the room enter the sleep state; adjusting the brightness of the lighting component according to the proportion of the number of the first people entering the sleep state in the current number of people, and when the proportion is 100%, controlling the lighting component to turn off.

[0005] Exemplarily, when the brightness of the lighting component is lower than a preset brightness threshold and the current number of people is determined to increase according to the number of people information, the brightness of the lighting component is increased.

[0006] Exemplarily, the lighting assembly includes a first lighting assembly and a plurality of second lighting assemblies. The lighting range of the first lighting assembly is larger than that of each second lighting assembly and overlaps with the lighting ranges of the plurality of second lighting assemblies. The controller is further specifically configured to: when the proportion of the number of first persons in the current number of persons is greater than a first threshold, control the first lighting assembly to turn off; and determine the positions of the second persons who have not entered the sleep state based on the vital sign information, and control the second lighting assemblies whose lighting ranges cover the second persons to operate in a lighting mode.

[0007] Exemplarily, the lighting assembly includes a first lighting assembly and a plurality of second lighting assemblies. The lighting range of the first lighting assembly is larger than that of the second lighting assemblies and overlaps with the lighting ranges of the plurality of second lighting assemblies. The controller is further configured to: determine the positions of the third persons with abnormal vital signs based on the vital sign information, and at least control the second lighting assemblies whose lighting ranges cover the third persons to operate in an alarm mode.

[0008] Exemplarily, the lighting fixture system further includes guiding lights, which are arranged on a predetermined route leading to a room. The controller is further configured to: when it is determined based on the vital sign information that any person in the room has abnormal vital signs, control the guiding lights to operate.

[0009] Exemplarily, there are a plurality of lighting assemblies, which are respectively used for a plurality of rooms. There are a plurality of guiding lights, which are arranged in sequence along the predetermined route. The predetermined route leads to a plurality of rooms. The controller is further configured to: determine the room where the third persons with abnormal vital signs are located based on the vital sign information, and make the guiding lights on the predetermined route leading to that room operate.

[0010] Exemplarily, the lighting fixture system further includes an execution component for controlling a room door. The controller is further configured to: when it is determined based on the vital sign information that the vital signs of the persons in the room are abnormal, control the execution component to open the door of the room where it is located.

[0011] Exemplarily, the proportion of the number of first persons in the current number of persons is negatively correlated with the brightness of the lighting assembly.

[0012] Exemplarily, the first mode is executed at night.

[0013] Exemplarily, the controller is used to control the lighting assembly in a second mode during the day. The second mode includes: determining based on the vital sign information whether the vital signs of the persons in the room are abnormal; when the vital signs of any person in the room are abnormal, controlling the lighting assembly to operate in an alarm mode; when the vital signs of all the persons in the room are normal, adjusting the brightness of the lighting assembly according to the ambient brightness.

[0014] Thus, when a person is in life danger or has died, the lighting system can issue an alarm prompt to remind medical staff to provide treatment or remind staff to take measures. The prompt is given through the lighting component without the need to set up additional components for alarming, and the light prompt is gentler than the sound generated by an alarm, etc., which can avoid causing excessive negative impacts on people in adjacent carriages. Moreover, the use of such a lighting system is relatively simple and does not require manual network connection, etc. When it is detected that the vital signs of the person are normal, the lighting system can also provide appropriate lighting according to the number of people and their sleep conditions, and thus can be applied to carriage rooms that are separated from each other and where people do not often move at night. When a person in the room enters the sleep state, the lighting brightness can be reduced until the lighting is turned off to avoid affecting sleep; when there are people moving at night, limited lighting can be provided to facilitate their movement, and the light is soft. When there is a crew member or other carriage passengers entering and strong light illumination is required, strong light illumination can be provided. The millimeter-wave radar has a high cost performance, and compared with a camera, it can avoid concerns about privacy while being able to obtain relatively accurate information about people and the room.

[0015] A series of simplified concepts are introduced in the Summary of the Invention, which will be further described in detail in the Detailed Description of the Invention section. The Summary of the Invention section is not intended to attempt to define the key features and essential technical features of the claimed technical solution, nor is it intended to attempt to determine the protection scope of the claimed technical solution.

DETAILED DESCRIPTION OF THE INVENTION

[0018] In the following description, numerous specific details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely exemplarily shows the preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0019] To thoroughly 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. However, in addition to these detailed descriptions, the present invention may also have other embodiments.

[0020] Embodiments of the present invention provide a lighting system. The lighting system according to the embodiments of the present invention will be introduced in detail below in conjunction with the accompanying drawings. In this application, the lighting system is used in a room for a predetermined number of people to sit and rest. The lighting system of this application is particularly applicable to the carriages of trains, high-speed trains or bullet trains. Since the number of passengers in each carriage is usually fixed, it is not easy to misjudge the number of people. The lighting system can also be applicable to other places where the activities of people are relatively fixed, such as rooms in nursing homes, living places such as employee dormitories. For ease of understanding, the following will take the application of the lighting system in a carriage as an example for detailed description.

[0021] The lighting system may include a lighting component and a controller. The lighting component is used in a room for a predetermined number of people to rest, and specifically may include light sources such as fluorescent lamps and LED lamps. In some embodiments, a light homogenizing plate is provided on the surface of some lamp beads to make the light softer. In the embodiments mentioned below, each lighting system may include a lamp with a light homogenizing plate and a spotlight with concentrated light, which can provide extensive lighting in the carriage and also provide lighting for a designated area in the carriage. The lighting component may include a radar.

[0022] The radar may include one or more of radar sensors such as millimeter-wave radar, microwave radar, ultrasonic radar, infrared radar, lidar, etc. Taking the case where the radar uses millimeter-wave radar as an example, the wavelength of the millimeter waves it uses is between microwaves and centimeter waves. Therefore, the millimeter-wave radar has some advantages of both microwave radar and optoelectronic radar. Overall, the millimeter-wave radar can detect the number of people and the movement of people, etc. For each person, the millimeter-wave radar can detect the minute activities of the person's body, such as breathing, heartbeat, etc., so as to determine the person's physical condition. In some embodiments, the millimeter-wave radar can also obtain information such as the gestures of the person and the arrangement of objects in the room where the person is located. Thus, the radar can be used to detect the situation information of the people in the room, where the situation information may include information about vital signs and the number of people. Using millimeter-wave radar can avoid the privacy problems caused by using cameras, and has high detection accuracy and wide applications. The radar may be integrated on the circuit board of the lighting component. Optionally, the controller may also be integrated on the circuit board of the lighting component.

[0023] The controller may be electrically connected to the lighting component to control the lighting component to work or stop working. The controller can also obtain the situation information of the people detected by the radar provided on the lighting component. In some other embodiments, the controller may be centrally arranged at a suitable position in each carriage to receive the information obtained by the radar in the carriage and correspondingly control the lighting component in the carriage to work. Optionally, the controller may be arranged in the power distribution box of the vehicle and electrically connected to the lighting components in one or more carriages at the same time. Optionally, the controller may also be a device similar to a smart speaker, and is electrically connected to each lighting component in the carriage through wireless communication, so as to receive the information obtained by the radar and correspondingly control the lighting component to work.

[0024] Specifically, the control device may be built with electronic components such as timers, comparators, registers, digital logic circuits, etc., or implemented with processor chips such as single-chip microcomputers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic arrays (PLAs), application-specific integrated circuits (ASICs), etc. and their peripheral circuits.

[0025] The controller is used to control the lighting component in a first manner. Figure 1The working flowchart of the lighting fixture system of the first exemplary embodiment is shown. The first mode includes determining whether the vital signs of the people in the room are abnormal based on the vital sign information. As mentioned above, the radar can detect subtle changes in the human body. For example, according to the vibration of the human body, information directly related to vital signs including respiration information and heartbeat information can be obtained. When the vital signs of any person in the room are abnormal, the controller can control the lighting component to work in an alarm mode. Specifically, for example, when a person has a serious illness, difficulty in breathing caused by various reasons, etc., the controller can obtain this information and can alarm by controlling the lighting component. For example, the controller can repeatedly turn on and off the lighting component, thereby generating a working mode completely different from the normal lighting mode. In some embodiments, the lighting component can emit lights of different colors, and the controller can control the lighting component to alarm with lights of a different color from the normal color. Optionally, the controller can also control the lighting component to alternately switch between lights of different colors. In some embodiments, the lighting component includes light beads with concentrated light, and the controller can control these light beads to flash, so as to avoid the alarm information being masked due to overly strong natural light during the daytime.

[0026] When the vital signs of all the people in the room are normal, the controller can determine whether the current number of people in the room is greater than a predetermined number based on the number of people information. Since the lighting fixture system is applied to a room with a relatively fixed number of people, it can be considered that when there are visitors in the room, the people in the room are in a relatively active state. For example, there may be situations where crew members come in and out. The controller can control the lighting component to work in a lighting mode when the current number of people is greater than the predetermined number. Thus, when it is detected that there are people entering the room of the carriage, the controller can control the lighting component to provide relatively bright lighting for them, so as to avoid inconvenience or even errors caused by dim light. When the current number of people is less than or equal to the predetermined number, it is considered that there are no visitors in the room. At this time, the controller can judge whether the people in the room have entered the sleep state based on the vital sign information. Specifically, it can be determined whether they have entered the sleep state according to the respiration and heartbeat frequencies of the people. On this basis, the brightness of the lighting component is adjusted according to the proportion of the number of the first people who have entered the sleep state in the current number of people, and when the proportion is 100%, the lighting component is controlled to turn off. Specifically adjusting the brightness of the lighting component can include: increasing or decreasing the voltage or current of the light beads in the lighting component, thereby changing its power; or adjusting the lighting power through pulse width modulation (PWM). In the embodiment where the lighting component mentioned below includes a plurality of sub-lighting components, such as the first lighting component and the second lighting component, the brightness of the local or overall lighting in the room can also be changed by turning on or off some of the sub-lighting components.

[0027] Thus, when there is a life-threatening situation or death of a person, the lighting system can issue an alarm prompt to remind medical staff to provide treatment or remind staff to take measures. By using the lighting component for prompting, there is no need to set up additional components for alarming, and the lighting prompt is gentler than the sound generated by an alarm, etc., which can avoid causing too much negative impact on the people in the adjacent compartments. Moreover, the use of such a lighting system is relatively simple and does not require manual network connection, etc. When it is detected that the vital signs of the person are normal, the lighting system can also provide appropriate lighting according to the number of people and their sleep situation, so it can be applied to compartments or rooms that are separated from each other and where people do not move around frequently at night. When there are people entering the sleep state in the room, the lighting brightness can be reduced until the lighting is turned off to avoid affecting sleep; when there are people moving at night, limited lighting can be provided to facilitate their movement and the light is soft. When there is a crew member or other passengers in the compartment and strong lighting is required, strong lighting can be provided. The millimeter-wave radar has a high cost performance, and compared with a camera, when it can obtain relatively accurate information about people and the room, it can avoid concerns about privacy.

[0028] As described above, adjusting the brightness of the lighting component may include turning off some sub-lighting components. In this embodiment, the following situation may occur: before the proportion of the number of the first people reaches the threshold, the brightness of the lighting component remains unchanged, and when the proportion of the number of the first people reaches the threshold, the brightness of the lighting component suddenly decreases. In other embodiments, the proportion of the number of the first people in the current number of people is negatively correlated with the brightness of the lighting component. In this way, as long as there are people entering the sleep state, the brightness of the lighting component can be reduced to remind others and at the same time reduce the impact on the sleep of this person. Optionally, the lighting component may include a sufficient number of sub-lighting components. As the number of the first people increases, the extinguished sub-lighting components also gradually increase until the entire lighting component is extinguished.

[0029] Exemplarily, the first method can be executed at night. Refer to Figure 2 , since usually sufficient lighting can be obtained from the window during the day, it may not be meaningful to control the lighting component to work, and it will cause waste of energy and even lead to too strong ambient light, affecting people's normal work and life. On the contrary, adjusting the lighting brightness of the lighting component according to the rest situation of people at night can significantly affect people's sleep situation and work and life situation. In this embodiment, the lighting system can have a night mode. Optionally, the night mode can be turned on at a fixed time period every day; optionally, the night mode can also automatically enter or exit according to the change of the ambient brightness, according to seasons, weather, etc. In short, the night mode can be considered as a mode for people to rest.

[0030] Exemplarily, the controller is further configured to control the lighting assembly in a second manner during the day. Continuing to refer to Figure 2 , the second manner includes determining whether the vital signs of the people in the room are abnormal based on the vital sign information, and when the vital signs of any person in the room are abnormal, controlling the lighting assembly to operate in an alarm mode. This is the same as the first manner. When the vital signs of the people in the room are normal, the controller may adjust the brightness of the lighting assembly according to the ambient brightness.

[0031] In the embodiment where the above lighting fixture system can detect the ambient brightness, the lighting fixture system may further include a light detection assembly for detecting the brightness of the carriage room. The light detection assembly may include a photoresistor, a photovoltaic cell, etc. In some embodiments, the light detection assembly may further include a solar panel disposed inside or outside the carriage. In some embodiments, the light detection assembly may be used to detect infrared rays and / or ultraviolet rays to distinguish natural light from artificial light sources. The controller is further configured to determine whether it is currently in the day period or the night period based on the current brightness and the brightness change of the carriage room. When it is in the night period, it enters the night mode, and when it is in the day period, it exits the night mode.

[0032] Exemplarily, when the brightness of the lighting assembly is lower than a preset brightness threshold and it is determined according to the personnel quantity information that the current personnel quantity increases, the brightness of the lighting assembly is increased. When there are crew members, staff members or other carriage passengers entering, lighting with relatively strong light can be provided. However, when the people in the room are in a sleeping state, suddenly increasing the brightness of the room to a large extent may seriously affect the mood of the people. And the light in the room needs to at least meet the needs of the entering people for walking, finding someone, and working. Therefore, the brightness threshold can be determined according to the lighting brightness required for an ordinary person to complete work, so as to timely increase the lighting brightness of the environment to the lighting brightness that an ordinary person can work in when the current environment is relatively dim.

[0033] Exemplarily, the lighting assembly may include a first lighting assembly and a plurality of second lighting assemblies. Figure 3 The working flowchart of the lighting fixture system according to the third embodiment of the present application is shown. The lighting range of the first lighting assembly is larger than the lighting range of each second lighting assembly, and there is an overlap with the lighting ranges of the plurality of second lighting assemblies. Continuing to take carriage lighting as an example, in a carriage, there may be multiple berths. The first lighting assembly may be one or more lighting lamps on the carriage top, which can provide overall lighting for the carriage room when lit; the second lighting assembly may be one or more reading lamps disposed at each berth position, which can provide local lighting for each berth area and hardly affect other berths.

[0034] The controller is further specifically configured to control the first lighting component to turn off when the proportion of the number of the first group of people in the current number of people is greater than a first threshold. The first threshold can be a proportion such as one half, one third, two thirds, etc. In some embodiments, the first threshold can also be set to 0. Thus, when the people in the room enter the sleep state, the environmental brightness can be timely reduced, and the influence on the people's sleep can be reduced. Moreover, the position of the second group of people who have not entered the sleep state is determined according to the vital sign information, and the second lighting component whose lighting range covers the second group of people is controlled to work in a lighting mode. In this way, good lighting can be provided for the people who need lighting, and the rest of other people is hardly affected.

[0035] Exemplarily, the controller can also be configured to determine the position of a third group of people with abnormal vital signs based on the vital sign information, and at least control the second lighting component whose lighting range covers the third group of people to work in an alarm mode. Specifically, for example, the first lighting component and the second lighting component corresponding to the third group of people can be controlled to work together in the alarm mode, so as to remind the people in the carriage to timely determine the people in need of help, provide assistance or call the crew for handling. Or, only the second lighting component corresponding to the third group of people works in the alarm mode, so as to remind the surrounding people to provide assistance to him or call the crew with less influence on the people in the carriage. In short, in this way, the people in need of help can be accurately located and an alarm can be issued in time.

[0036] Exemplarily, the lighting fixture system can further include guiding lights, which are arranged on a predetermined route leading to the room. The guiding lights can include indicating lights with arrow signs, ordinary circular lights or spotlights, etc. The controller is further configured to control the guiding lights to work when it determines that any person in the room has abnormal vital signs based on the vital sign information. Specifically, the guiding lights can be used as ordinary lighting lights in daily situations, and work in an alarm mode when the vital signs of the people are abnormal. Optionally, the guiding lights can be lit only when the vital signs of the people are abnormal. Thus, the information that the people need help can be quickly conveyed to the staff, and the staff can be guided to the target room. Optionally, the alarm mode of the guiding lights can include flashing, color changing, breathing lights or flowing water lights, etc., which can at least remind the staff to pay attention.

[0037] Exemplarily, there can be multiple lighting components, which are respectively used for multiple rooms. The guiding lights can also be set to be multiple and arranged in sequence along the predetermined route, and the predetermined route leads to multiple rooms. Specifically, for example, the guiding lights can extend from a fork in the road to multiple rooms respectively, or there are multiple rooms on a corridor, and the guiding lights extend on the corridor.

[0038] The controller is further configured to: determine the room where the third person with abnormal vital signs is located based on the vital sign information, and cause the guiding lights on the predetermined route leading to the room to operate. In the embodiment where the guiding lights include arrows, the controller may control the arrows to point to the room; in some embodiments, the guiding lights may be lit from a fork in the road or the end of the corridor to the door of the room; in some embodiments, the guiding lights may be in the form of running lights and be lit in a cycle from a fork in the road or the end of the corridor to the door of the room. In short, multiple guiding lights can clarify the location of the room and prevent medical staff or crew members from arriving at the wrong room.

[0039] Exemplarily, the lighting fixture system further includes an execution component for controlling the room door, and the controller is further configured to: when it is determined based on the vital sign information that the vital signs of the person in the room are abnormal, control the execution component to open the door of the room where it is located. Optionally, the door of the room may be configured as an automatic door, and the execution component may control the opening and closing of the room door. Optionally, the execution component may be the door lock of the room, and the execution component may allow the room door to be locked or unlocked. In short, when the vital signs of the person in the room are abnormal, the room door can be automatically opened or unlocked, facilitating the crew or medical staff to quickly enter the room for treatment and preventing delays in treatment time.

[0040] Exemplarily, when entering the night mode, the controller is further configured to determine the number of people in the carriage room based on the personnel situation information and use this number of people as the predetermined number. The people in the carriage may also, for various reasons, fail to board the train or temporarily leave the carriage. This will cause changes in the people in the carriage, resulting in a situation where the controller misjudges and continuously controls the lighting component to be lit or operate at a lower brightness. By resetting the predetermined number each time the night mode is entered, the lighting can be provided in an appropriate manner in the night mode. In this way, after existing people leave or new people enter, there is no need to manually change the predetermined number, and the lighting of the lighting fixture system is more intelligent.

[0041] For the lighting fixture systems of some embodiments, they may obtain the current time information by connecting to the Internet or manually inputting the current time, etc. For the lighting fixture systems of some embodiments, they may include a time module, and the accurate time can be entered at the time of factory. However, except for obtaining time through the Internet or radio, the time obtained by other methods will gradually have a large error with use and needs to be calibrated. Connecting to the Internet and manually inputting time also require relatively cumbersome operations.

[0042] Through the change of ambient brightness, the lighting system can know the approximate time period of a day without manual or network connection, and can be automatically adjusted with the change of seasons. For example, the time to turn on the night mode is relatively late in summer and relatively early in winter. Since the opening of the night mode of the lighting system does not require very precise time, the time period is roughly obtained by light, and the error is acceptable. In some embodiments, after detecting that it is getting dark, the lighting system will not immediately enter the night mode, but can delay the daytime mode for one or several hours to meet the normal life of people and provide higher-brightness lighting. In some embodiments, similarly, when detecting that it is getting light, the lighting system will not immediately switch to the daytime mode, but remain in the night mode to provide sufficient sleep for people. Optionally, the controller can comprehensively consider the light changes in two or more days and automatically adjust the time period of entering the night mode for each future day to avoid the controller's misjudgment of time due to rainy days or similar abnormal weather conditions.

[0043] For ease of understanding, the mode in which the lighting system is in other than the night mode can be referred to as the daytime mode. In the daytime mode, optionally, the lighting system can be turned on or off by a conventional manual switch; optionally, based on the light information of the light detection component, when the brightness in the carriage is relatively low, the lighting component can be controlled to turn on to supplement the light in the carriage. In some embodiments, in the daytime mode, the lighting system may have no difference in function from an ordinary lighting system.

[0044] Exemplarily, the controller is further configured to enter the night mode when determining that the number of people in the carriage room is less than or equal to the first ratio based on the personnel situation information. Specifically, the first ratio can be one-third. Taking a carriage with three people as an example, when there is only one person or no one is active in the carriage room, it can be considered that most people have gone to bed or are about to go to bed. To avoid disturbing the rest of these people, the controller enters the night mode. Optionally, the first ratio can also be one-half. For a carriage with three people, only no one is active, one person is active, two people are active, or three people are active. Therefore, it is still when there is only one person or no one is active in the carriage room that most people are considered to have gone to bed or are about to go to bed.

[0045] The controller is further configured to exit the night mode when determining that the number of people in the carriage room is greater than or equal to the second ratio based on the personnel situation information. Thus, the conventional lighting in the daytime mode can be turned on at an appropriate time period. The second ratio can be greater than the first ratio. Continuing with the embodiment where the first ratio is one-third, the second ratio can be two-thirds. In this way, when there are three people in the carriage, the night mode will only be exited when two people or three people are active, avoiding seriously disturbing the sleep of most people.

[0046] When the activation of the lighting system affects everyone simultaneously, when multiple people in the carriage are about to go to sleep, they don't want the others to turn on the lights and affect their sleep. During the daytime, when multiple people are active, there is also a high probability of waking up the others. By using the lighting system of the above embodiment, the lighting needs of most people in the same carriage can be taken into account to a certain extent.

[0047] Exemplarily, the controller is further configured to determine, based on the personnel situation information, the time period during which a proportion of the people in the carriage room greater than or equal to a third proportion are all active. And based on the time period, control the lighting component to gradually increase the brightness in a manner simulating sunlight. To improve the quality of life of the personnel, before the personnel wake up, by gradually increasing the brightness of the lighting component, the overall brightness in the carriage can be gradually increased to conform to the effect of natural light, thereby playing a role in waking up the personnel. This can enable the personnel to have a better experience after waking up. By using this lighting system, it can be applied to carriages with poor daylighting through windows and carriages with relatively thick curtains. This can also conform to the living habits of most people. The third proportion is similar to the second proportion and can meet the living habits of most people in the carriage. The third proportion can be greater than, less than, or equal to the second proportion, but is usually greater than the first proportion.

[0048] Exemplarily, the alarm state of the lighting component can be manually turned off. Optionally, the alarm mode of the lighting system can be turned off through a remote control or a key switch. In some embodiments, the alarm mode of the lighting system can be turned off by detecting a change in the number of people, such as when a medical staff member enters the carriage or someone goes out to seek help. This can avoid the working state of the lighting component during alarm, which may affect the lighting effect of the lighting system or the state of the personnel. Thus, it can be avoided that the alarm state delays the treatment of medical staff or affects the subsequent use of the carriage.

[0049] Exemplarily, the lighting component includes a plurality of sub-lighting components arranged at multiple positions in the carriage room. The sub-lighting components can include lights with relatively concentrated light, such as spotlights. The personnel situation information also includes information about the position of the personnel, and can detect the position of the personnel in the carriage. The radar is also used to detect the map in the carriage room. Specifically, the radar can determine structures in the carriage such as tables, chairs, beds, and the corners of the carriage walls. The controller is further configured to control at least the sub-lighting component closest to the boundary among the plurality of sub-lighting components to emit light when the minimum distance between the personnel position and the boundary of the map is less than a first threshold. During the night-time activities of the personnel, these sub-lighting components in the corresponding areas can indicate these areas such as the corners of the table and the edges of the seats, thereby avoiding bumps and falls due to poor visibility.

[0050] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation terms such as "front", "rear", "upper", "lower", "left", "right", "lateral", "vertical", "perpendicular", "horizontal", "top", "bottom", etc. are usually based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description. Without contrary statements, these orientation terms do not indicate or imply that the devices or elements referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of the present invention; the orientation terms "inner" and "outer" refer to the inside and outside relative to the contour of each component itself.

[0051] For convenience of description, regional relative terms such as "above...", "over...", "on the upper surface of...", "above-mentioned", etc. can be used here to describe the regional positional relationships of one or more components or features shown in the drawings with other components or features. It should be understood that the regional relative terms not only include the orientations of the components described in the drawings but also different orientations during use or operation. For example, if the components in the drawings are inverted as a whole, the components "above other components or features" or "over other components or features" will include the situations where the components are "below other components or structures" or "under other components or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". In addition, these components or features can also be positioned at other different angles (such as rotated 90 degrees or other angles), and this document is intended to cover all such situations.

[0052] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, components, assemblies, and / or combinations thereof.

[0053] It should be noted that the terms "first", "second", etc. in the description, claims, and above-mentioned drawings of the present application are used to distinguish similar elements and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order different from those illustrated or described here.
