This application is a national stage patent application of PCT application No. PCT/CN2015/075523, filed on Mar. 31, 2015. This application claims the priority of Chinese Patent Application No. 201410184520.2, entitled “Wireless Network System and Smart Device Management Method using LED Lighting Devices,” filed on Apr. 30, 2014, the entire contents of which is incorporated herein by reference.
FIELD OF THE DISCLOSURE
The present disclosure relates to the field of wireless network technologies and, more particularly, relates to a wireless network system using LED lighting devices and a smart device management method thereof.
BACKGROUND
LED (Light Emitting Diode) is a solid-state semiconductor device that can directly convert electrical energy to visible light. LED technologies provide many advantages including high energy efficiency, eco-friendliness, controllable lighting, being highly practical, high stability, short response time, long lifespan, etc. To promote low carbon living and protect environment, LED technologies have been widely adopted in various lighting applications.
WI-FI technology enables personal computers, hand-held devices (such as PDAs, mobile phones) and other smart terminals to interconnect with each other wirelessly, and is widely used in connecting and forming network with a variety of network terminals.
With the development of smart technologies, home life is also becoming more intelligent. Smart home technologies can link a variety of devices in the house together (such as audio and video equipment, lighting system, curtain control, air conditioning control, security system, digital cinema system, network appliance, and system for automatically reading and sending utility bills, etc.) through network technologies, and provide a variety of functions including appliance control, lighting control, curtain control, telephone remote control, indoor and outdoor device remote control, anti-theft alarm, environmental monitoring, HVAC control, infrared repeater and programmable timing control, enabling a full range of information interaction capabilities. Smart home technologies not only help families to maintain a smooth external information exchange flow, optimize people's lifestyle, and use time efficiently, but also enhance home life security, and can even save money in energy costs.
In order to achieve interconnections among a variety of devices in a smart home, it is critical to set up the home network. Currently there are two options to build the network: wired and wireless. Users often like to perform data communication at any place, which cannot be realized by fixed-wire networks. The fast development of wireless communication technologies has brought new opportunities to home network building technologies. Currently, one option to set up the WI-FI network is using a home wireless router, which provides a wireless network that connects with other terminals and appliances. However, as the signal coverage area of the wireless router is limited, it is relatively difficult to build a complete network with this option. Further, this option cannot realize interconnection between smart terminals and appliances. An alternative option to build WI-FI network is using cascade connection of several wireless routers. However, after cascading, the IP address of each smart terminal is not in the same network segment, it is not only complicated for the smart terminals and appliances to access the network, but also difficult to set up centralized control. Therefore, a wireless network system with wide coverage, convenient access, and ability to achieve interconnections among connected devices would be beneficial. The disclosed method and system are directed to solve one or more problems set forth above and other problems.

When the wireless router is connected to the Internet, the LED lighting devices may respectively access the Internet through the wireless router or the wireless network provided by other arbitrary LED lighting devices that have been wirelessly connected with the wireless router. The smart terminals may connect to the Internet via the wireless router or the LED lighting devices.
It is understood that the smart terminal may be a telephone, a computer, a cell phone, a smart appliance, etc. That is, any terminals or devices that have wireless access capabilities may be considered as smart terminals and access the wireless network provided by the LED lighting devices or the wireless router.
Preferably, the LED lighting devices may be set up and distributed at different locations in a home environment according to the home layout. Each LED lighting device may be installed within the coverage of the wireless network provided by at least one other LED lighting device or the wireless router. Since LED lighting devices are common and necessary equipment in home life, providing WI-FI modules in the LED lighting devices enables smart control of the LED lighting devices. Further, using LED lighting devices as connection nodes in the wireless network system not only provides a wide range coverage, but also ensures the stability of the wireless network system.
In another embodiment consistent with present disclosure, as illustrated in FIG. 2 , the wireless router is connected to the Internet, and its own IP address is configured as 192.168.1.1. The DHCP (Dynamic Host Configuration Protocol) server may allocate the address segment as 192.168.1.100-192.168.1.200. LED lighting device 1 may access the wireless network provided by the wireless router. The IP address obtained by WI-FI module 1 may be 192.168.1.100. In the meantime, PDA 1 may freely choose to access the wireless network provided by the wireless router, with an allocated IP address of 192.168.1.101. LED lighting device 2 may connect to the wireless network provided by LED lighting device 1 , with an obtained IP address of 192.168.1.103. Meanwhile, a computer PC 1 may join the wireless network provided by LED lighting device 1 , with an allocated IP address of 192.168.1.102.

INDUSTRIAL APPLICABILITY AND ADVANTAGEOUS EFFECTS
Without limiting the scope of any claim and/or the specification, examples of industrial applicability and certain advantageous effects of the disclosed embodiments are listed for illustrative purposes. Various alternations, modifications, or equivalents to the technical solutions of the disclosed embodiments can be obvious to those skilled in the art and can be included in this disclosure.
The present disclosure has several advantages. Comparing to the prior art, the present disclosure provides a wireless network using LED lighting devices, which fully exploits the locations and application characteristics of LED lighting devices in home and work environments. By providing each LED lighting device with a WI-FI module that has wirelessly access point and network switch functions, the LED lighting devices may be used as network nodes, and form a network with a wireless router through wireless switching cascade connections.
When building a network through cascade connection of wireless routers, the network addresses of terminals and devices would not be in the same network segment. It may be difficult to implement fast and convenient mutual access between the smart terminals and devices, and to perform mutual control among the network terminals and devices, therefore not convenient for centralized management of home devices.
The present disclosure provides a wireless switch cascade method. The WI-FI modules of the LED lighting devices have the capabilities of a wireless switch, which enable the IP addresses of the accessed devices and the module itself to be in the same network segment. Therefore, in a wireless network consistent with the present disclosure, any two terminals or devices can interconnect. Such a wireless network has wide range coverage, is easy to access, and enables the connected devices to perform information exchange freely without location limitations. In the entire network structure, the smart terminals or devices can access the network at any location in the network coverage area, and can perform centralized control on the smart devices. The connected devices are no longer limited by space and can wirelessly connect with each other freely, further enhancing the users' smart home user experience.
