Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0035] Example 1

[0036] The present application provides an intelligent lighting system for a limited space, as shown in FIG1 , including: a multi-position sensor, a controller, and at least one adjustable light source, wherein:

[0037] Multi-position sensors are located at multiple locations within the target confined space and are used to collect at least one type of sensor information. A controller is used to obtain the sensor information fed back by the multi-position sensors and, based on the preset lighting conditions of the target confined space, generate control instructions to control the power of the adjustable light source to achieve the preset lighting conditions. Specifically, the controller in the embodiment of the present application comprehensively analyzes the actual sampling results of all sensors within the confined space to form a brightness output plan and, in the form of control instructions, synchronously controls the adjustable light source to achieve precise brightness output in different areas of the space.

[0038] In an embodiment of the present application, a multi-position sensor includes: a ground sensor, a wall-mounted sensor, and a hanging sensor. The ground sensor, the wall-mounted sensor, and the hanging sensor all include: at least one of: a photosensitive sensor, an acoustic wave sensor, a temperature sensor, a humidity sensor, a pressure sensor, and a vibration sensor. Among them, the use scenario of the photosensitive sensor is, for example: the controller controls the adjustable power supply to achieve the preset lighting conditions based on the brightness information of the current room fed back by the photosensitive sensor; the use scenario of the acoustic wave sensor is, for example, in an area where people do not often go (for example, in a corridor), by collecting the size of the sound waves generated during the movement of people, the controller uses this to adjust the light intensity / lighting power of the preset area where the current person is located; the use scenario of the temperature sensor is, for example: if a certain area of ​​the room is greatly affected by the temperature, the heat will cause the lamp to heat up seriously, and the controller adjusts the light intensity / lighting power of these areas of the room based on the temperature feedback received from the temperature sensor in this area to ensure the long service life of the lamp. The power of the lamp; the use scenario of the humidity sensor is, for example: if a certain area of ​​the room is greatly affected by humidity, because the wall is polluted due to the humid environment, the reflectivity of the wall may be reduced, and the controller receives the humidity feedback of the humidity sensor in this area, and adjusts the light intensity / lighting power of these areas of the room; the use scenario of the pressure sensor is, for example: the sensor is subjected to the size of the external force of the person, and the controller uses this to adjust the light intensity / lighting power of the preset area where the person is currently located; the use scenario of the vibration sensor is, for example: if the vibration of the equipment in a certain area of ​​the room is greatly affected, the controller receives the vibration feedback of the vibration sensor in this area, and adjusts the light intensity / lighting power of these areas of the room.

[0039] In practical applications, the detailed layout of various sensors can be configured for detailed brightness zoning based on user needs. For example, if a user requires the same brightness within a 1-square-meter confined space, while adjacent spaces maintain the same or different brightness levels, the various sensors should be arranged with 1 square meter as the minimum unit. Furthermore, the installation options for various sensors should be designed based on their sampling characteristics for various influencing factors. For example, if a user requires a certain brightness level on a certain floor within a confined space, an illuminance floor sensor should be installed on the floor of that space. For example, if a user requires sound (human or object sounds) within a certain space as a feedback factor for adjusting the brightness of that area, an acoustic suspension sensor should be installed at a certain height within the space as the acoustic sampler for that area. Furthermore, if nearby walls affect the actual acoustic sampling in that area, an acoustic wall-mounted sensor should be placed on the nearby wall to perform sampling corrections on the acoustic suspension sensor in that area to ensure the accuracy of acoustic sampling in that area.

[0040] In one specific embodiment, the controller includes a human-computer interface for obtaining user-entered preset lighting conditions for a target effective space and / or configuration information for multi-position sensors. Specifically, the human-computer interface allows users to customize and optimize the intelligent lighting system by configuring the usage of different position sensors and desired lighting conditions based on actual needs. This adapts to diverse lighting system usage scenarios and provides users with a superior lighting experience. Furthermore, the human-computer interface can display operating status information for the multi-position sensors and adjustable light sources, facilitating monitoring of actual usage.

[0041] In one embodiment, the controller includes: an operation unit and at least one control unit. The operation unit is used to obtain sensor information fed back by multi-position sensors set in various areas within a limited space and generate control instructions for different areas and send them to the control unit. The control unit controls the power of the adjustable power supply in its area according to the control instructions to achieve preset lighting conditions.

[0042] Specifically, in one application scenario, the target effective space is divided into four areas, and the lighting area requirements of each area are different. Correspondingly, different multi-position sensor types are set. The operation unit can use different algorithms to couple the various sensor information fed back by the multi-position sensors according to the lighting requirements of different areas to generate corresponding control instructions. The control unit can be a PID controller, which is respectively set to control the adjustable power supply in the corresponding area, and based on the light information fed back by the photosensitive sensors set in each area, continuously adjusts the adjustable power supply until the preset lighting conditions are reached. The specific connection diagram is shown in Figure 2. The multi-position sensor types set in each area in Figure 2 are only for example description and are not limited to this.

[0043] In practical applications, signals can be transmitted between multi-position sensors, controllers, and adjustable light sources through wireless or wired communication, and can be reasonably configured according to the actual application scenario.

[0044] When wireless communication is employed, the intelligent lighting system provided in the embodiments of the present application further includes: wireless communication devices, each provided on the multi-position sensor, the controller, and the adjustable light source, for transmitting signals between the controller and the multi-position sensor and the adjustable light source, respectively. Specifically, a wireless transmitter is provided on the multi-position sensor to transmit the sensor information collected by the transmitter to the controller; a wireless transceiver is provided on the controller to receive the sensor information transmitted by the multi-position sensor and generate control instructions to transmit to the adjustable power source; and a wireless receiver is provided on the adjustable power source to receive the control instructions transmitted by the controller. Wireless transmission can reduce the workload of engineering construction such as pre-wiring.

[0045] When wired communication is employed, the intelligent lighting system provided in embodiments of the present application further includes cables for electrically connecting the controller to the multi-position sensor, and for electrically connecting the controller to the adjustable power supply. This enables signal exchange between the controller, the multi-position sensor, and the adjustable power supply, thereby ensuring stable and real-time signal transmission.

[0046] The intelligent lighting system for a confined space provided in the embodiment of the present application provides real-time feedback on the actual environmental perception within the target confined space by setting distributed sensors that affect light, forming a negative feedback system. This can achieve high-precision brightness control at the spatial level and ensure that the brightness at different locations within the target confined space always meets the preset requirements.

[0047] Example 2

[0048] The present application provides an intelligent lighting control method for a limited space, as shown in FIG3 , including the following steps:

[0049] Step S301: Obtaining lighting influencing factor information and preset lighting conditions of a target limited space.

[0050] Specifically, the preset lighting conditions can be set according to the user's personalized needs based on different application scenarios, or the minimum illumination value for this application scenario can be set according to the lighting design specifications. The lighting influencing factors can be determined based on the actual environmental conditions in the target limited space and the collection characteristics of various sensors, and the user can input information through the manual interaction interface.

[0051] Step S302: Determine the location and type of the multi-position sensor according to the lighting influencing factor information and the preset lighting conditions.

[0052] Specifically, multi-position sensors should be designed based on the lighting system's sampling characteristics for various influencing factors. For example, if a specific floor within a confined space is required to maintain a certain brightness, an illuminance floor sensor should be installed on the floor within that space. If sound (human or object sounds) is used as a feedback factor to adjust the brightness of a specific area within that space, an acoustic suspension sensor should be installed at a certain height within the space to serve as the acoustic sampler for that area. Furthermore, if nearby walls affect the actual acoustic sampling of that area, an acoustic wall sensor should be installed on the nearby wall to perform sampling corrections on the acoustic suspension sensor in that area to ensure the accuracy of the acoustic sampling in that area.

[0053] The preset lighting conditions used in this application can be set based on the lighting requirements of different zones within the target confined space. For example, a user may require that the brightness within a 1-square-meter confined space be maintained constant, while adjacent spaces maintain the same brightness or a different brightness. In this case, the various sensors should be arranged with 1-square-meter as the minimum unit. This is for example only and is not intended to be limiting.

[0054] Step S303: acquiring sensing information fed back by the multi-position sensors, and generating a control instruction based on the preset lighting conditions of the target effective space to control the power of the adjustable light source to achieve the preset lighting conditions.

[0055] The specific process involves obtaining at least one type of sensor information from multiple position sensors, combining it with the preset lighting conditions of the target effective space to generate a control instruction to control the power of the adjustable light source. Furthermore, the system obtains brightness information from multiple photosensors and continuously modifies the power adjustment signal in the control instruction based on this brightness information until the preset lighting conditions are achieved. This control process ensures that the impact of various factors on brightness can be corrected in real time, more accurately ensuring the brightness of the light receiving point in the area, achieving continuous brightness changes, and more accurately adjusting the brightness perception of the sensory organs in the area, while also providing a positive user experience.

[0056] The intelligent lighting control method for a confined space provided in the embodiment of the present application has the function of autonomous configuration of lighting needs. Users can freely define the area division rules with different brightness levels within the confined space. By increasing the number of sensors and light sources, the brightness of different areas in the confined space can be continuously and accurately changed as needed, meeting the usage needs of scenes with higher brightness requirements.

[0057] Although the embodiments of the present application have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the appended claims.
