As shown in FIG. 1, the exemplary system may include at least one LED lighting device 1, a smart home control server 2, and at least one smart terminal 3.
There is no limitation on the quantity of LED lighting devices. A user may configure the number of LED lighting devices according to the indoor room space and practical needs. Generally, a plurality of LED lighting devices may be distributed at different locations in an indoor and/or an outdoor space. The smart home control server 2 may be a server in the home network or a cloud server. The smart terminal 3 may be various household electrical appliances, such as a smart refrigerator, a smart air conditioner, a speaker, a smart phone, a smart watch, a tablet computer, a laptop computer, a telephone, etc. Different types and quantities of smart terminals should not limit the scope of the present disclosure. Users may select one or more smart terminals according to practical situations.
In the exemplary system for controlling a smart home environment using one or more LED lighting devices, the LED lighting device 1, the smart home control server 2 and the smart terminal 3 may form an integrated smart home control system by interacting with each other. The LED lighting device 1 and the smart home control server 2 may be configured to respectively include a communication module for performing data interactions between the LED lighting device 1 and the smart home control server 2. The smart terminal 3 may also be configured to include a communication module for exchanging signals with the smart home control server 2. In certain embodiments, the LED lighting device 1 may wirelessly communicate with the smart home control server 2. Further, the smart terminal 3 may also wirelessly communicate with the smart home control server 2. The communication modules may be a wireless communication module such as a WI-FI module, a Bluetooth module, etc. It is understood that the above-described communications may also be realized by wired connections.
The LED lighting device 1 may be configured to not only include a common LED light-emitting component to provide lighting, but also integrate a video acquisition module. The video acquisition module may be configured to collect video and/or image data in a detection range. The LED lighting device 1 may send the video data to the smart home control server 2 through the communication modules provided in the LED lighting device 1 and the smart home control server 2. After receiving the video data, the smart home control server 2 may perform image processing and recognition to detect behavioral information of a person and/or an object in the video. Further, the smart home control server 2 may generate control instructions according to the behavioral information and send the control instructions to the smart terminal 3 through the communication modules of the smart home control server 2 and the smart terminal 3.
It should be noted that, the smart terminal 3 may be any kind of home electrical appliances including the LED lighting device 1. The smart home control server 2 may also control the LED lighting device 1.
In one embodiment, the exemplary system may be used to recognize illegal activities and trigger corresponding control responses. For example, the smart home control server 2 may detect behavioral information in the video data about a person or an object breaking in a door or a window. Such behavioral information is recognized as an illegal activity. The smart home control server 2 may generate control instructions and send the control instructions to the smart terminal 3, such as a smart phone, the LED lighting device 1, and/or a speaker. The control instructions may be configured to control the smart terminal 3 to generate alarms by sound, light, and/or vibration. The smart terminal 3 may receive the control instructions and initiate the alarm. Further, the smart home control server 2 may also send control instructions to a telephone. The telephone may receive the control instructions and initiate a call to the police.
In another embodiment, the exemplary system may be used to recognize unsafe behaviors and trigger corresponding control responses. For example, the smart home control server 2 may detect behavioral information in the video data about an elderly person or a child tripping or falling. Such behavioral information is recognized as an unsafe behavior. The smart home control server 2 may generate control instructions and send the control instructions to the smart terminal(s) 3 such as a smart phone, and/or an LED lighting device. The control instructions may be configured to control the smart terminal 3 to generate alarms by sound, light and/or vibration.

In certain embodiments, to increase intelligent level of a smart home control system, besides recognizing illegal or unsafe activities and generate corresponding alarms, the exemplary system may further recognize users' specified instructive behaviors and perform corresponding controls. The specified instructive behaviors may include general activities of daily life. The specified instructive behaviors may be considered as behavioral information and recognized by the smart home control server 2. For example, the smart home control server 2 may detect a specified instructive behavior of a person drawing a circle in the air. The smart home control server 2 may recognize such behavior as turning the light on. For another example, the smart home control server 2 may detect a specified instructive behavior of a person of a person making a cross with his/her hands and recognize such behavior as turning the light off. In another example, the smart home control server 2 may detect a specified instructive behavior of a person doing a fanning gesture and recognize such behavior as turning on an air conditioner.
It is understood that users may customize different types of instructive behaviors and corresponding control instructions in the smart home control server 2 in advance. After recognizing an instructive behavior, the smart home control server 2 may generate control instructions and send to a corresponding smart terminal 3, an LED lighting device, or an air conditioner. The smart terminal 3 may operate according to the control instructions.
Direct data interactions between the LED lighting device 1 and the smart home control server 2 and signal exchanges between the smart home control server 2 and the smart terminal 3 may together enable various user controls over a smart home environment. Further, users may use the smart terminal 3 to configure the LED lighting device 1 and the smart home control server 2 according to practical needs. In certain embodiments, the smart terminal 3 may interact with the LED lighting device 1 through their communication modules and configure parameters of various functional components of the LED lighting device 1. The smart terminal 3 may also configure the smart home control server 2 through the communication modules. Details are described later in relation to other embodiments.
In the exemplary system for controlling a smart home environment using one or more LED lighting devices, the LED lighting device 1 may collect video data and send to the smart home control server 2 using data paths between the LED lighting device 1 and the smart home control server 2. The smart home control server 2 may parse the video data to detect behavioral information and generate corresponding control instructions. The smart home control server 2 may send control instructions to the smart terminal 3 through signal paths between the smart home control server 2 and the smart terminal 3. The smart terminal 3 may receive the control instructions and operate accordingly.
Comparing to the prior art, the exemplary system does not require additional components to set up specialized monitoring devices. The LED lighting devices may include integrated video acquisition capabilities, which is covert and may have good surveillance results. Further, such configuration may save spaces and make the smart home environment simple and comfortable. On the other hand, through interactions among the LED lighting device 1, the smart home control server 2 and the smart terminal 3, controlling the smart home environment may become more efficient and convenient.

The embodiments above describe the interaction process among three entities including the LED lighting device, the smart home control server and the smart terminal from a system perspective. The following embodiments will illustrate advantageous hardware improvements and/or software configurations of these entities.
FIG. 2 is a structure diagram illustrating an exemplary LED lighting device consistent with various embodiments of the present disclosure. As shown in FIG. 2, the exemplary LED lighting device 1 may include an LED light-emitting module 21, a power supply module 22, a video acquisition module 23, a processing module 24 and a communication module 25.
The power supply module 22 may be electrically connected to the LED light-emitting module 21, the video acquisition module 23, the processing module 24 and the communication module 25. The processing module 24 may be electrically connected to the video acquisition module 23 and the communication module 25.
The video acquisition module 23 may be configured to collect video data within a camera capture range, and send the video data to the processing module 24.
The processing module 24 may be configured to control the communication module 25 to send the video data to a smart home control server 2.
In certain embodiments, the video acquisition module 23 may be a camera fitted for the structure and size of the exemplary LED lighting device 1. Specific model of the camera may be configured according to practical needs to integrate the camera with the LED lighting device. In an exemplary embodiment, the camera may have auto-focus functionalities and be able to adjust camera angles freely for a desirable shooting effect. The video acquisition module 23 may include the camera having auto-focus capabilities and an angle-adjustment structure. The camera may be connected to the angle-adjustment structure. The camera and the angle-adjustment structure may be electrically connected to the processing module. The angle-adjustment structure may be configured to rotate and turn the camera to adjust shooting angles when receiving control instructions from the processing module. In some embodiments, the camera may be placed on a panel or a housing of the LED lighting device. It is understood that, the position of the camera may vary according to the overall shape and structure of the LED lighting device.
In various embodiments of the present disclosure, the exemplary LED lighting device 1 further includes the video acquisition module 23. The video acquisition module 23 and the LED light-emitting module 21 may both use the power supply module 22 for obtaining power supply, and use the processing module 24 for receiving control instructions.
The LED light-emitting module 21 and other modules usually require a DC supply voltage and the required supply voltage is usually low. An exemplary hardware implementation of the LED lighting device may provide a viable structure for the power supply module 22 to facilitate integration of various modules including the video acquisition module 23.
In the exemplary hardware implementation, the power supply module 22 may include a rectifier circuit and step-down circuit. An input of the rectifier circuit may be electrically connected to an external AC power supply (e.g. a household power outlet). An output of the rectifier circuit may be electrically connected to an input of the step-down circuit. The LED light-emitting module 21 usually requires different a supply voltage than those of the processing module 24, the video acquisition module 23 and the communication module 25. The step-down circuit may be configured to convert the output of the rectifier circuit to various voltages to satisfy voltage requirements of different modules. In one embodiment, a first voltage output of the step-down circuit may be electrically connected to the LED light-emitting module 21. A second voltage output of the step-down circuit may be electrically connected to the processing module 24, the video acquisition module 23 and the communication module 25. The first voltage and the second voltage may be determined by specifications of the LED light-emitting module 21, the processing module 24, the video acquisition module 23, and the communication module 25.
The processing module 24 may function as a central control element of the exemplary LED lighting device 1. The processing module 24 may be configured to control transmissions between the communication module 25 and a communication module of the smart home control server 2, and send video data to the smart home control server 2. In certain embodiments, when the video acquisition module 23 is collecting video data, the video may stay the same for a long period of time (e.g., video of a hall way with no human traffic). In order to save energy and preserve resources, the processing module 24 may further be configured to determine whether the video data collected by the video acquisition module 23 is changed during a preset time duration. When there is no change for the preset duration, the processing module 24 may stop the communication module 25 from transmitting the video data to the smart home control server 2, until the processing module 24 determines that the video data collected by the video acquisition module 23 has changed. When the video data has changed, the processing module 24 may control the communication module 25 to resume sending the video data to the smart home control server 2.
In some embodiments, the LED lighting device 1 may be considered the smart terminal 3 and controlled by the smart home control server 2. Further, the processing module 24 may electrically connect to the LED light-emitting module 21. The communication module 25 may further be configured to receive control instructions from the smart home control server 2 and send the control instructions to the processing module 24. The control instructions may be used to instruct the LED light-emitting module 21 to adjust lighting brightness and/or to flash. The processing module 24 may control the LED light-emitting module 21 to operate according to the control instructions.
In various embodiments of the present disclosure, the exemplary LED lighting device 1 may integrate a video acquisition module and a communication module. Besides providing normal lighting functions (e.g., lighting up a room), the exemplary LED lighting device may collect video data and transmit the collected video data to a smart home control server through signal exchanges between the LED lighting device and the smart home control server. The smart home control server may parse and process the video data to detect behavioral information and generate corresponding control instructions. The smart home control server may send control instructions to a smart terminal through signal exchanges between the smart home control server and the smart terminal. The smart terminal may receive the control instructions and operate accordingly. Such configuration does not require additional effort to set up specialized monitoring devices. The exemplary LED lighting device may integrate video acquisition capabilities. Such an LED lighting device with integrated video acquisition capabilities is covert and may provide good surveillance results. Further, such configuration may save space and make the smart home environment simple and comfortable. On the other hand, the exemplary LED lighting device may integrate a communication module to facilitate interactions with a smart home control server. Such configuration enables timely detection and prevention of illegal activities and/or unsafe behaviors, as well as recognition and execution of specified user instructions, which may expand various applications of smart terminals at home.
On the basis of various embodiments illustrated in FIG. 2, the exemplary LED lighting device 1 may further integrate other functional modules. As shown in FIG. 3, the exemplary LED lighting device 1 may further include a light sensor 26 and a supplemental infrared light module 27. The supplemental infrared light module 27 may be electrically connected to the power supply module 22 and the processing module 24. The light sensor 26 may be electrically connected to the power supply module 22 and the processing module 24.
The light sensor 26 may be configured to detect light intensity in a surrounding area of the LED lighting device 1 and send the light intensity data to the processing module 24.
The processing module 24 may further be configured to control an on/off status of the supplemental infrared light module 27 and an intensity of supplemental light provided by the supplemental infrared light module 27.
In certain embodiments, for example, when no one is at home at night, the LED light-emitting module 21 of the LED lighting device 1 may be off, thus there may be poor lighting around the exemplary LED lighting device 1 and video data collected by the video acquisition module 23 may be too dark. The smart home control server 2 may have difficulty parsing and recognizing the video data. The exemplary LED lighting device 1 may further include the light sensor 26. The light sensor 26 may be composed with various photosensitive units and configured to determine ambient light intensity around the LED lighting device. The processing module 24 may further be configured to control the supplemental infrared light module 27 to switch on and increase an intensity of supplemental light provided by the supplemental infrared light module 27. When the light intensity detected by the light sensor 26 reaches a certain value, the processing module 24 may further be configured to control the supplemental infrared light module 27 to decrease the intensity of the supplemental light, or to turn off the supplemental infrared light module 27.
In addition, the exemplary LED lighting device 1 may further integrate an audio acquisition module 28 which may supplement the video data collected by the video acquisition module 23. The audio acquisition module 28 may be a microphone and configured to collect audio signals. Similarly to the video data transmission method, the audio acquisition module 28 may send audio signals to the processing module 24. The processing module 24 may be configured to control the communication module 25 to send the audio signals to the smart home control server 2.
In certain embodiments, for example, the video acquisition module 23 may collect video data about someone or some objects entering from a door or a window, while the audio acquisition module 28 may collect glass shattering sounds from the door or the window or other destruction sounds. The smart home control server 2 may combine these video and audio signals to recognize the behavioral information as an intrusion, and generate corresponding control instructions to control the smart terminal 3.
The above embodiments describe how various modules integrated in the exemplary LED lighting device 1 function and connect with each other. Further, the exemplary LED lighting device may interact with the smart terminal 3 through the communication module 25 to facilitate user configurations on the various functional modules. For example, a user may install an APP on the smart terminal 3 such as a mobile phone or a tablet computer. When using the APP, the user may set configuration information of the exemplary LED lighting device 1 by menu options or manual input. The configuration information may include operation parameters of at least one of the LED light-emitting module 21, the video acquisition module 23, the light sensor 26 and the audio acquisition module 28. The operation parameters may include but not limited to on-time, off-time, intensity of a light emitted by the LED light-emitting module 21, a camera angle of the video acquisition module 23, etc. The smart terminal 3 may use its communication module to transmit the configuration information to the communication module 25 of the exemplary LED lighting device 1. The communication module 25 may send the configuration information to the processing module 24. The processing module 24 may control an operational state of corresponding module(s) according to the configuration information.
In various embodiments consistent with the present disclosure, the exemplary LED lighting device 1 may further integrate the light sensor 26 and the supplemental infrared light module 27, which may provide supplemental light to the video acquisition module 23 when there is poor lighting. The exemplary LED lighting device 1 may further integrate the audio acquisition module 28, which allows the smart home control server 2 to perform comprehensive analysis and detect behavioral information combining both video and audio data. The precision of behavior recognition may be enhanced. Further, through data interactions between the communication modules of the smart terminal 3 and the exemplary LED lighting device 1, users may easily configure various function modules of the exemplary LED lighting device through the smart terminal 3, which enhances user experience.
FIG. 4 is a structure diagram illustrating an exemplary smart home control server consistent with various embodiments of the present disclosure. As shown in FIG. 4, the exemplary smart home control server 2 may include a communication module 41 and a processing module 42. The communication module 41 and the processing module 42 may be electrically connected.
The communication module 41 may be configured to receive a video data from the LED lighting device 1 and send the video data to the processing module 42.
The processing module 42 may be configured to parse and process the video data to detect behavioral information, generate control instructions according to the behavioral information and control the communication module 41 to send the control instructions to corresponding smart terminal 3.
The exemplary smart home control server 2 may be a server in a home network or a cloud server. The processing module 42 may first parse and process the video data to detect behavioral information. The behavioral information may be a hand gesture, a limb movement, an action or a combination thereof. The processing module 42 may then generate control instructions according to the recognized behavioral information. For example, in the embodiment described in FIG. 1, the recognized behavioral information may be an illegal intrusion. The processing module 42 may generate control instructions to instruct a smart terminal 3 to give sound, light and/or vibration alarms. The smart terminal 3 may be an LED lighting device, a speaker, a smart phone, etc. Further, the processing module 42 may instruct a telephone to call the police. Other applications described in previous embodiments may also be employed in the exemplary smart home control server 2 and are not repeated here. It should be noted that, the processing module 42 may implement various existing image recognition algorithms to perform image recognition, and generate control instructions according to the recognition result.
Further, in certain embodiments, the exemplary smart home control server 2 may further include a memory module 43 (not shown). The memory module 43 may be electrically connected to the processing module 42 and configured to store video data, audio data, a behavior database, and/or a control instruction library. The behavior database and/or the behavioral instruction library may be preset. The processing module 42 may recognize and compare the video data with behavioral data stored in the behavior database in the memory module 43, and obtain matching behavioral information. The behavioral information may be, for example, image date related to a person breaking into a building, a person falling down, a person breaking into a vehicle, two people fighting, etc. Further, the processing module 42 may search corresponding control instructions in the instruction library. The instructions may be, for example, initiating a sound alarm at the smart terminal 3, flashing the light of the LED light emitting module 21, or initiating an emergency call by the smart terminal, etc.
In embodiments consistent with the present disclosure, each piece of behavioral information may correspond to one or more instructions in the instruction library. The LED lighting device 1, through the processing module 24, may look up one or more instructions based on the determined behavioral information. For example, if the process module 24 determines that a person has fallen down based on the collected video data, the process module 24 may look up the instructions corresponding to that behavioral information (a fall) in the instruction library. The instructions corresponding to an identified fall may be initiating one or more emergency calls on smart terminal 3, turning on the LED lighting device at the location of the fall, etc.
In some embodiments consistent with the present disclosure, the processing module 24 may determine the behavioral information based on both the video data acquired by the video acquisition module 23 and the audio data acquired by the audio acquisition module 28. In some cases, the video data and audio data may both indicate the same behavioral information (e.g., a fall, a break-in, etc.). The processing module 24 may determine the behavioral information. The processing module 24 may further look up the instructions corresponding to the behavioral information in the instruction library. In other cases, the video data and audio data may indicate different behaviors (e.g., video data indicating a fall while audio data indicating a break-in). The processing module 24 may then identify the behavioral information as “undetermined.” The instruction corresponding to the “undetermined” behavioral information in the instruction library may be to notify the smart terminal 3 or other terminals connected to the smart home control server 2 that the video and audio data need to be reviewed by a user. Such a notification may be a message displayed on a user interface, a call to a designated number, an audio notification pushed to one or more areas inside or outside the home, or a combination thereof. Further, when the behavioral information is “undetermined,” the processing module 24 may adjust the settings for the corresponding lighting emitting module 21, video acquisition module 23, and audio acquisition module 28 so that the future behavior recognition results may be more accurate. For example, the processing module 24 may increase the brightness level of the lighting emitting module 21 at the monitored location; adjust the relevant orientation of the video and audio acquisition modules 23 and 28 to achieve better behavior recognition results.
In addition, when the LED lighting device 1 integrates the audio acquisition module 28, the communication module 41 of the exemplary smart home control server 2 may receive audio data from the LED lighting device 1. The processing module 42 may be configured to parse and recognize behavioral information according to both the video data and the audio data. Detailed description may be found in various embodiments according to FIG. 3.
It should be noted that, users may upload the behavior database and/or the behavioral instruction library to the smart home control server 2 in advance. Users may also customize the behavior database and/or the behavioral instruction library in advance. Further, entries in the behavior database and the behavioral instruction library may be added, deleted or updated according to practical needs. In certain embodiments, users may directly log into the exemplary smart home control server 2 to upload and/or update data in the behavior database and/or the behavioral instruction library. Further, users may also use the smart terminal 3 to upload and/or update data to the exemplary smart home control server 2. For example, a user may install an APP on the smart terminal 3 such as a mobile phone or a tablet computer. When using the APP, the user may input data entries by menu options or manual input. The smart terminal 3 may send the data entries to the exemplary smart home control server 2 through its communication module. The processing module 42 may store the data entries in the memory module 43.
Further, to allow users to watch video data collected by the LED lighting device 1 in real-time, the processing module 42 may control the communication module 41 to send the video data to the smart terminal 3. When the smart terminal 3 is installed with the APP, users may play the video data through the APP.
In various embodiments consistent with the present closure, the exemplary smart home control server 2 may interact with the LED lighting device 1 and the smart terminal 3 through their communication modules. The exemplary smart home control server 2 may parse and recognize video data to detect behavioral information and generate corresponding control instructions. The smart home control server 2 may send control instructions to the smart terminal 3 through signal exchanges between the smart home control server 2 and the smart terminal 3. The smart terminal 3 may receive the control instructions and operate accordingly. Through interactions among the LED lighting device 1, the smart home control server 2 and the smart terminal 3, controlling the smart terminals may become more efficient and convenient. The LED lighting device, the smart home control server and the smart terminal may enable timely detection and prevention of illegal activities and/or unsafe behaviors, as well as recognition and execution of specified user instructions, which may expand various applications of smart terminals at home.

For example, the control instructions may notify a smart terminal with lighting capabilities to produce alarms by light. In another example, the control instructions may notify a smart terminal with voice capabilities to produce alarms by sound/announcement. In another example, the control instructions may notify a smart terminal with vibration capabilities to produce alarms by vibration. Further, for devices such as a refrigerator or a smart air-conditioner, the control instructions may notify them to power on and set a desired temperature.
