簡易、可互操作的無線照明控制

　　簡易、可互操作的無線照明控制

　　利用ZigBee光鏈路實現(xiàn)照明控制解決方案（ZLL）在EmberZNet PRO平臺標準，設(shè)計人員可以利用一個強大的和可互操作的解鎖新的和令人興奮的消費者集中照明應(yīng)用的網(wǎng)絡(luò)解決方案。

　　消費者在控制家用電器時重視方便，并且隨著彩色LED技術(shù)的最新進展，家庭中選擇和修改環(huán)境照明的可能性比以往任何時候都大。無線網(wǎng)絡(luò)進一步使照明控制的新的可能性，使它更容易和更具成本效益的改造現(xiàn)代照明系統(tǒng)，同時也使照明系統(tǒng)的控制器更方便地使用在建筑物內(nèi)或周圍的任何地方。

　　這一新興的無線照明控制市場迄今為止已被一系列解決方案所服務(wù)，每一種解決方案都有其自身的長處和短處。一個特別的問題是，消費者沒有簡單的方法來確保任何一個產(chǎn)品都能與另一個產(chǎn)品合作，因此用戶在一段時間內(nèi)逐步擴展他們的家庭照明系統(tǒng)是非常困難的。此外，這種網(wǎng)絡(luò)所需的一些復(fù)雜的調(diào)試過程常常意味著用戶需要增加新設(shè)備，即使使用同一制造商的產(chǎn)品時也是如此。其他解決方案可能需要高成本的專業(yè)安裝程序。

　　By defining a common standard available to all product designers， the new lighting profile from the ZigBee Alliance addresses both of these issues. Developed in cooperation with major global lighting manufacturers， ZigBee Light Link （ZLL） not only describes an application messaging protocol for advanced lighting control， but it also includes a mechanism which makes out-of-the-box commissioning as simple for the consumer as pushing a button. In addition to these new features， the ZigBee Light Link profile also leverages the key characteristics common to all ZigBee profiles – robust and secure mesh networks based on low-power， low-cost IEEE 802.15.4 radio technology.

　　Simple device commissioning

　　As with any new consumer technology， complexity （real or perceived） is a significant barrier to growth. A key principle during the development of the ZLL profile was that the operation of the system be highly intuitive， and certainly no more complex than a traditional wired lighting system. Figure 1 below shows some possible commissioning use cases to demonstrate the ease with which ZigBee Light Link products can be used.
