For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, as will be appreciated by those of ordinary skill in the art, in the various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments may be mutually combined and referred to without contradiction.

A first embodiment of the present application relates to an indoor lighting device, as shown in fig. 1, at least comprising: a lighting unit 101, a Wi-Fi unit 102, and a Wi-Fi controller 103.

The Wi-Fi controller 103 is configured to control an operation state of the Wi-Fi unit 102 and/or the lighting unit 101 according to a user instruction; the lighting unit 101 is used for providing illumination for an indoor area; wi-Fi unit 102 is used to provide a local area network, i.e., WLAN, covering an indoor area. Based on this, the Wi-Fi controller 103 is connected to the Wi-Fi unit 102 and the lighting unit 101 through control circuits, respectively, so that the Wi-Fi unit 102 and the lighting unit 101 can receive control signals from the Wi-Fi controller 103 and operate according to the control signals.

The Wi-Fi unit 102 may have one or more of an AP mode, a wireless routing (Router) mode, a relay (Repeater) mode, a Bridge (Bridge) mode, a Client (Client) mode, etc. in providing a WLAN, and in order to be able to provide a WLAN, it typically includes a Wi-Fi radio circuit subunit and a Wi-Fi radio antenna subunit in order to transceive signals externally. And to further facilitate the external service of the Wi-Fi unit 102 and the normal operation of the Wi-Fi unit 102, as shown in fig. 2, the indoor lighting device further includes a gigabit ethernet transformer 104 and an ethernet device 105, wherein the ethernet device 105 mainly includes at least one ethernet interface, thereby providing routing and/or switching capability of the ethernet port to the WLAN, and logic control capability.

It should be noted that in an indoor environment, the lighting device is generally disposed at a position where light can cover the indoor space to the greatest extent, and thus, when a Wi-Fi unit for providing WLAN is deployed into the device where the lighting unit is located, the position where the Wi-Fi unit is located can be kept together with the lighting device to cover the indoor space to the greatest extent. If the WiFi equipment and the lighting equipment are simply deployed in the same equipment, larger volume can be occupied, and the control unit correspondingly configured by the Wi-Fi unit is utilized, namely the WiFi controller is used for realizing intelligent control of the lighting unit, the intelligent of the lighting unit can be realized without additionally adding equipment, the increase of cost is avoided, and the household intelligence can be realized.

It is understood that the lighting unit may consist of at least one lighting subunit into a light group. The lighting sub-units may be Light-Emitting Diode (LED) lamps, fluorescent lamps, energy-saving fluorescent lamps, etc., and the number of the lighting sub-units included in the lighting unit may be not limited, one or more lighting sub-units may be provided, or the combination of the lighting sub-units may be not limited, or the lighting sub-units may be arranged to form a square matrix, or may be arranged randomly, or in particular, the lighting sub-units may be closely arranged to reduce the volume of the lighting unit, and the cross section of each lighting sub-unit may be a regular hexagon, a rectangle, etc.

Further, since the light group including the plurality of illumination sub-units can provide different illumination modes, different illumination modes can also indicate different information, and therefore, the light group can also be used for indicating the working state of the Wi-Fi unit, that is, the illumination relationship of different colors of the illumination sub-units in the light group corresponds to different working states, or the different illumination conditions of the illumination sub-units in the light group corresponds to different working states, and the like. For example, the working state of the Wi-Fi unit may have a normal working state, an overload working state, an idle state and the like, the lamp group is formed by arranging three rows of LED lamps, the normal working state of the Wi-Fi unit corresponds to the case that only one row of LEDs in the lamp group is turned on and provides strong light illumination, the idle state of the Wi-Fi unit corresponds to the case that only two rows of LEDs in the lamp group are turned on and provide medium strong light illumination, the overload working state of the Wi-Fi unit corresponds to the case that all three rows of LEDs in the lamp group are turned on and provide weak light illumination, and the like, so that the color and the switch control of the LED lamp group are combined into the controllable LED lamp group, and the controllable LED lamp group is used as one of the user interactive display interfaces of the Wi-Fi unit, which is not repeated herein. Of course, when the lighting unit has only one lighting sub-unit, the lighting sub-unit can still indicate the working state of the WiFi unit by providing different color lighting rays, which will not be described in detail herein.

It will also be appreciated that the Wi-Fi controller needs to receive instructions from the user before controlling the Wi-Fi unit and/or the lighting unit in accordance with the user instructions. The user instructions can be issued by a user directly through a console associated with Wi-Fi control, such as a remote controller, an interaction interface provided by an indoor lighting device, and the like, or can be realized through a user intelligent terminal and a server, such as a mobile phone, a tablet, and the like. When implemented by a user's smart terminal, such as a mobile phone, a tablet, and the like, and a server, the user's smart terminal is typically provided with an associated application program, the user describes user operation requirements by accessing the application program and setting the application program, the application program reads a user setting result and generates a user instruction to send the user instruction to the server, the server sends the received user instruction to the indoor lighting device and receives the received user instruction by a Wi-Fi controller of the indoor lighting device, and JavaScript object notation (JavaScript Object Notation, JSON) protocol communication protocol and DH (Diffie-Hellman) security encryption protocol may be used for communication among the application program, the server, and the indoor lighting device, which is not limited in this embodiment.

Thus, in some examples, the Wi-Fi controller is further configured to receive a user instruction sent by the user through the cloud server. The user instructions may include, among other things, status query instructions and/or operation control instructions. Specifically, the user instructions include, but are not limited to: query class commands: status query for indoor lighting, service activation status query for indoor lighting, running status query for indoor lighting, and operation class command: the method comprises the steps of performing an on operation on a Wi-Fi unit and/or a lighting unit, performing an off operation on the Wi-Fi unit and/or the lighting unit, controlling the illumination color of the lighting unit, adjusting the illumination brightness of the lighting unit, controlling the display condition of the lighting unit, setting a service set identifier (Service Set Identifier, SSID), a WLAN key or a WLAN security protocol of the Wi-Fi unit in an AP mode, performing uplink access in a Repeater mode, performing AP searching in the Repeater mode, performing AP association in the Repeater mode and the like.

In the scenario that the network access mode of the user intelligent terminal shown in fig. 3 is a fixed access network access so as to realize control over indoor lighting equipment based on a cloud server, a user sends a user instruction to the cloud server through executable configuration end software of the intelligent terminal or an application program on an intelligent mobile system and the like based on the fixed access network and carries relevant instruction parameters such as a registered user number, wherein the instruction parameters can indicate the content of an instruction to be executed, including but not limited to service activation state inquiry, equipment state inquiry, on/off of lighting equipment, wi-Fi function on/off, WLAN configuration modification and the like; then, the cloud server sends a user instruction through the fixed access network and carries relevant instruction parameters, such as a registered user number and the like, to the indoor lighting device, and executes a state synchronization or remote control command. And after the indoor lighting device acts according to the user instruction, the cloud server returns an execution result of the user instruction to be used as a response based on the fixed access network, and then the cloud server returns the received response to the intelligent terminal based on the fixed access network and finally presents the response to the user. Of course, the result of executing the user instruction may be a successful response or a failed response.

In the scenario that the network access mode of the user intelligent terminal shown in fig. 4 is mobile data network access so as to realize control over indoor lighting equipment based on a cloud server, a user sends a user instruction to the cloud server through executable configuration end software of the intelligent terminal or an application program on an intelligent mobile system and the like based on the mobile data network of the intelligent terminal and carries relevant instruction parameters, such as a registered user number, wherein the instruction parameters can indicate the content of an instruction to be executed, including but not limited to service activation state inquiry, equipment state inquiry, lighting equipment on/off, wi-Fi function on/off, WLAN configuration modification and the like; then, the cloud server sends a user instruction based on the fixed access network and carries relevant instruction parameters, such as a registered user number and the like, to the indoor lighting device, and executes a state synchronization or remote control command. And after the indoor lighting device acts according to the user instruction, the cloud server returns an execution result of the user instruction to be used as a response based on the fixed access network, and then the cloud server returns the received response to the intelligent terminal based on the mobile data network and finally presents the response to the user. Of course, the result of executing the user instruction may be a successful response or a failed response.

Therefore, no matter what way the intelligent terminal of the user accesses the network, the control of the indoor lighting device can be realized through the cloud server, wherein the control of the indoor lighting device can be realized through the mobile data network, as long as the mobile data network of the intelligent terminal of the user is available, the control of the indoor lighting device through the fixed access network does not need to depend on the mobile data network of the intelligent terminal, and the limitation of the state of the mobile data network of the intelligent terminal is avoided.

Since the fixed access network and the mobile data network are not the focus of the present embodiment, the fixed access network, the mobile data network, and the like will not be described in detail.

It should be further noted that, in the case where intelligent control needs to be performed on the Wi-Fi unit and the lighting unit, registration activation is generally further required, and the Wi-Fi controller is further configured to initiate a service activation request to a server, such as a cloud server, and receive a service activation result returned by the server. The service registration activation process is usually started when the indoor lighting device is powered on for the first time or a factory configuration restoration is executed, and in particular, key information of the indoor lighting device needs to be carried for verification each time of registration activation.

In some examples, the Wi-Fi controller includes a main processor (central processing unit, CPU) and a lighting driver chip, the CPU is configured to control the Wi-Fi unit via a high-speed serial computer expansion bus standard (peripheral component interconnect express, PCIe), the CPU is further configured to control the lighting driver chip to drive the lighting unit via a general purpose input/output port (General Purpose Input Output, GPIO). That is, as shown in fig. 2, the lighting unit 102 is connected to the CPU in the Wi-Fi controller 103 through the driving chip in the Wi-Fi controller 103, where the driving chip and the CPU communicate through the GPIO interface.

It is considered that circuit ripple, radiation, etc. of the lighting unit may affect signal transceiving of the Wi-Fi unit. In order to reduce the influence as far as possible, when the circuit of the indoor lighting device is deployed, the circuit of the lighting unit and the radio frequency links of the Wi-Fi unit are respectively arranged on two sides of the circuit board of the indoor lighting device, so that the circuit of the lighting unit and the radio frequency links of the Wi-Fi unit are far as possible, and the interference of circuit ripple, radiation and the like of the lighting unit on the Wi-Fi unit is reduced.

In addition, considering that the Wi-Fi controller is usually implemented based on an embedded operating system, such as a Linux system, in order to maintain the normal operation of the Wi-Fi controller, it is generally required to update the version of the embedded system in time, record the execution condition of the user instruction, record the operation data of the Wi-Fi controller, and the like.

Based on this, as shown in fig. 2, the indoor lighting apparatus further includes a storage unit 106, wherein the storage unit 106 is configured to store data information of the indoor lighting apparatus.

In particular, the storage unit 106 may include a memory subunit and a storage subunit, where the memory subunit may be configured to store data necessary for normal operation, and the data may be dynamically stored, where the stored data may be used to load embedded operating system usage, and the storage subunit may be configured to store static data, such as embedded operating system data and user profile data. The memory subunit in this embodiment may be a serial peripheral interface (Serial Peripheral Interface, SPI) FLASH, non-volatile FLASH memory (Nor FLASH), nand FLASH, hard disk, etc., and the memory subunit may be a double rate synchronous dynamic random access memory (Double Data RateRandom Access Memory, DDR RAM) etc.

In particular, the indoor lighting device requires external power supply, and thus, as shown in fig. 2, the indoor lighting device further includes a power supply unit 107, wherein the power supply unit 107 is configured to convert external alternating current into direct current to power the Wi-Fi controller 103, the lighting unit 101, and the Wi-Fi unit 102.

The present embodiment is not limited to the power supply unit 107, and may be any device or device group capable of receiving an external power source and performing ac/dc conversion. In particular, when the weak current that the control circuit of the Wi-Fi controller 103 can receive cannot be directly provided from the outside, the power supply unit 107 may further include a transformer or the like to convert the current provided from the outside into the weak current that the Wi-Fi controller 103 can receive, which will not be described in detail herein.

In particular, as shown in fig. 2, the indoor lighting device further includes a key group 108, where the key group 108 communicates with the CPU in the Wi-Fi controller 103 through a GPIO interface, so as to implement control of the Wi-Fi controller 103 on the key group 108.

It should be noted that, the devices such as the power supply module 107, the key set 109, the gigabit ethernet transformer 104 and the like shown in fig. 2 are not required to be deployed in the indoor lighting device at the same time, and may be selectively deployed according to the needs, which will not be described in detail here.

It will also be appreciated that Wi-Fi units are integrated with lighting units such that the coverage of WLAN provided by Wi-Fi units is maximized based on the characteristic that lighting units are typically positioned in a location where the lighting rays are able to cover as much of the indoor area as possible, but still full coverage of the entire indoor area is not guaranteed.

Based on this, as shown in fig. 5, the indoor lighting device further includes a power line communication (Power Line Communication, PLC) unit 109, wherein the PLC unit 109 is configured to provide a network for an indoor area where the local area network provided by the Wi-Fi unit does not cover.

It is worth mentioning that the PLC unit can be used as a communication unit designed in a special application scene, and a commonly available network is provided for covering dead angle areas, so that the indoor communication problem that a remote distance in a room, especially a Wi-Fi unit cannot cover a room without wired network deployment, is solved. At this time, the indoor lighting device may cover a separate special room as a Wi-Fi AP.

The indoor lighting equipment provided by the embodiment can replace the existing household lighting bulb on the premise of not obviously increasing the cost of the whole hardware, has the lighting function, the intelligent function of the lighting system and the Wi-Fi indoor coverage function, and effectively solves the indoor coverage problem of WLAN. Meanwhile, the Wi-Fi controller multiplexing the Wi-Fi units gives consideration to the intelligent upgrading and reconstruction requirements of the lighting equipment, meanwhile, the Wi-Fi units and the intelligent lighting equipment in the intelligent home are in seamless butt joint, a complete solution is provided for users, the colors and the switch control of the lamp groups can be combined into controllable lamp groups, the lamp groups are used as one of user interaction presentation interfaces of the Wi-Fi units, and complex service interaction presentation and personalized presentation are realized. And based on the complex lamp language presenting function realized by the lighting equipment, a unique indoor Wi-Fi equipment is created.

It should be noted that, under some circumstances that WLAN coverage is not particularly required, the lighting unit in the above embodiments may be replaced by other indoor user devices, such as a refrigerator, a sound box, an air purifier, a fan, etc., which also can realize the intellectualization of other home appliances with low cost, and provide the indoor coverage function of the Wi-Fi unit, which will not be described here again.

It should be noted that, each module in this embodiment is a unit module, and in practical application, one unit may be one physical unit, or may be a part of one physical unit, or may be implemented by a combination of multiple physical units. In addition, in order to highlight the innovative part of the present application, elements that are not so close to solving the technical problem presented in the present application are not introduced in the present embodiment, but it does not indicate that other elements are not present in the present embodiment.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific embodiments in which the present application is implemented and that various changes in form and details may be made therein without departing from the spirit and scope of the present application.
