Mesh網絡有助于節約能源通過智能LED在家居照明控制

　　節能可以通過切換到LED照明在家里是眾所周知的。它已被廣泛記錄，低功耗，高效率的LED燈具可以降低功耗超過80%時相比，傳統的來源，如鹵素和白熾燈。不太好理解的是，智能照明控制可以刮掉更多的電費賬單。智能控制功能，通過傳感器和無線網絡，包括自動調光和關閉燈在無人的房間。

　　智能照明控制的市場，越來越多地被安裝作為家庭自動化系統的一部分，被認為是一個巨大的機會，在更廣泛的物聯網（物聯網）運動。然而，市場增長的關鍵是靈活和靈活的配置和安裝，以及成本低，投資回報快。

　　本文將考慮一些適用于國內應用的控制策略和無線網絡協議，專注于新的替代方案，建立ZigBee光鏈路。這些包括專有的協議，如線程和csrmesh技術。

　　ZigBee benefits

　　For some years， ZigBee Light Link has been regarded as the protocol of choice for smart lighting in the home， and has begun to amass a sizeable installed base. ZigBee has a number of advantages over alternative network strategies for home automation. It is established， proven， well supported and dedicated to low power sensing and control applications that demand low latency. Importantly， it is designed to support a mesh network topology， allowing alternative routes between controllers and nodes. This is essential for a flexible and scalable system， such as domestic lighting， that requires centralized， automatic， and programmable controls， as well as remote and manual ‘point’ controls.
