Intelligent lighting technology has received more and more attention, and it has become the first wave of the Internet of Things. The intelligent lighting gateway is a key link in this wave of enthusiasm. Grasping it in the explosive growth that may be foreseen in the future will play the role of “the ear of the cowâ€. Gateway: Provide the foundation for lighting networks Today, there are still two key issues that need to be addressed: the interoperability of new and old systems and the end-to-end analytical capabilities. Although the Internet of Things has the suspicion of "industrial heat, cold market", it has not yet ushered in a real outbreak, but smart lighting has the advantages of safety, energy saving, comfort, and efficiency. Its application in home and office is promising. In the period, it is expected that there will be a large-scale replacement for traditional lighting. In this regard, Ryan Zahn, general manager of NXP's global lighting product line, said: "Customer experience will be one of the most critical factors affecting the smart lighting market." Intelligent gateways play an important role in lighting systems. Intelligent lighting uses the existing computer network technology to connect various lamps to the network, and realizes centralized control and management of lighting fixtures through the network. The intelligent gateway is the internal transmission and control center of the intelligent lighting network, which directly determines whether the intelligent lighting network can be established quickly. In other words, the gateway provides a foundation for lighting network construction. Adam Burns, director of product marketing and business planning for Intel's IoT Solutions Group, said that the Internet of Things is growing stronger around the world. However, to date, there are still two key issues that need to be addressed: the interconnection of new and old systems and the end-to-end analytical capabilities. We believe that only by successfully solving these two problems can the Internet of Things be fully developed. In order to efficiently collect useful data from the original independent devices and transmit them to the cloud for integration and analysis in the cloud, intelligent gateways are indispensable. Status: Multi-gateway solutions exist for a long time As one of the distributed or multiple gateway solutions, the lighting gateway will exist in the market in large quantities and for a long time. With the emergence of new home gateway products, the focus on different types of applications on one device will be the future trend of home gateway research and development. However, due to the different characteristics of different external access networks, different service providers also have different business models. Therefore, it is difficult to have a single home gateway solution for a period of time. The lighting gateway is distributed or multiple. One of the gateway solutions will be in the market in large and long-term existence. “Intelligent lighting gateway system can realize centralized management and control of modules such as intelligent switches and sockets through wireless. The number of controllers is increased according to the actual size of the unit, thus solving the problem of limited wireless distance. The lighting gateway puts the appliances in the home and The centralized management of the lights allows for rich management and control functions,†said Ryan Zahn. Murata said that the end devices we use today, such as mobile phones and PADs, have Wi-Fi capabilities but no ZigBee communication capabilities, so if you want to use these end devices for control, you need a signal conversion process. The gateway is for this purpose. Murata's gateway for intelligent systems can understand and control the entire intelligent system in various environments and situations, and connect residential facilities such as lighting and home appliances through the network to communicate with each other, even if not at home, through a smartphone or tablet. Various devices to control and collect information. Trend: Support for multiple communication standards In the case of Wi-Fi, GPRS and other communication protocols vying to enter the Internet of Things, the solution to support multiple communication standards will become the future development trend. Zigbee has been the mainstream technology for intelligent lighting transmission protocols. Murata said that compared with other wireless communication technologies, ZigBee has low power consumption, low data volume, high anti-interference and high confidentiality. And features that cannot be ignored are automatic dynamic networking and the function of the self-contained cluster library (ZCL). These features make ZigBee's application in the smart lighting industry easier and simpler. Murata's choice of intelligent lighting is also the communication method of ZigBee. However, as one of the Internet of Things systems, the intelligent lighting system not only connects through ZigBee, but also supports the multi-communication standard when multiple communication protocols such as WiFi and GPRS enter the Internet of Things. In terms of technology, Murata's recently launched mini-gateway can realize the coexistence of 2.4GHz ZigBee and WiFi in the same frequency band, so that the two wireless communication modes work simultaneously in the same frequency band, and can maintain good performance without disturbing each other; In terms of services, Murata provides a complete set of solution design services behind the mini-gateway, from efficient and stable wireless communication software design to mobile device-side application software systems and application cloud service software development, in addition to CE, OFCA, ZigBee and WiFi and other certification requirements. NXP Semiconductors introduced the LightPRO solution, which is responsible for source code conversion between the WiFi router and the JenNet IP or ZigBee protocol suite. After the intranet obtains the TCP/IP command, the gateway converts it to JenNet Ip or ZigBee and sends it to the wireless lighting control unit. The wireless module consists of an RF receiver and an MCU. It receives commands from the gateway and takes action to manage and control the LED dimming driver. Marvell also launched the "ZigBee+WIFI" solution to solve the problem of RF distance and flexibility, providing consumers with a better experience. System: Let various devices work together seamlessly The LightPRO module acts as a common application layer, allowing devices from different vendors to work together seamlessly. After all, the gateway is only one component of the intelligent lighting system. It is the key to realize more flexible control and diversified functions. Based on the lighting gateway, Murata's intelligent lighting system includes ZigBee modules connected to LED lamps and different types of control devices, such as remote control, human body detection and control devices, illumination sensing devices, and APP software for smart devices. Human body, illumination adjustment, monochrome light control, color temperature light control, color light (RGB) light control and other functions. Ryan Zahn also said that in the gateway system with LightPRO controlling building lighting, each gateway can operate up to 500 nodes, and each floor can have a gateway. The system can be expanded as needed without any restrictions. Just add more to the system. Multiple gateways are all. The LightPRO solution has simple hardware requirements, no control lines, easy installation, flexible grouping, and remote dimming. The preset system and scene settings bring a good user experience. Most importantly, the LightPRO module can act as a common application layer, allowing devices from different vendors to work together seamlessly.
Intergrated Solar Street Light means the Solar Panel and head of light are intergraged together,just show as two opposite sides.
the advantage contains :no need to lay cables and ac power supply,just supply the power with sunlight,in case of no electricity charges; DC power supply,photosensitive control.
