智能照明工程的無線技術選擇
?

ZigBee無線技術以其?Zigbee Light Link（ZLL）簡介（包括支持網(wǎng)狀網(wǎng)絡，智能家居應用基礎）已經(jīng)證明了自己的智能照明應用的一個強有力的候選人。然而，ZigBee沒有市場本身。智能照明行業(yè)正走向繁榮，這吸引了其他無線技術廠商的競爭。各自主張自身優(yōu)勢。

本文基于早期高新區(qū)智能照明的文章通過比較優(yōu)勢和競爭劣勢與ZigBee無線技術。文章概述了芯片和模塊可供硅廠商熱衷于說服照明設計師把他們的無線技術進入下一個智能照明產(chǎn)品。

There have been many attempts to endow lighting with a degree of "intelligence." Much of the early effort was targeted at energy saving and was based on using the existing power cables as a data corridor. Lighting was also wired up to sensors that detected daylight and/or movement. Such systems were proprietary, expensive, and difficult to install. Today, however, smart lighting is a key element of home automation. Contemporary systems differ from the clunky products of yesteryear by fusing two young technologies––Solid State Lighting (SSL) and wireless connectivity. SSL enables a wide range of luminosity, color, and temperature which infuses each room (or even different parts of the same room) with a different ambience, while wireless connectivity makes it easy for the consumer to select that ambience from a remote control device (often a smartphone) either while at home or located remotely (Figure 1).
