ZigBee無線技術(shù)以其?Zigbee Light Link（ZLL）簡介（包括支持網(wǎng)狀網(wǎng)絡(luò)，智能家居應(yīng)用基礎(chǔ)）已經(jīng)證明了自己的智能照明應(yīng)用的一個強(qiáng)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(shù)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(shù)。文章概述了芯片和模塊可供硅廠商熱衷于說服照明設(shè)計(jì)師把他們的無線技術(shù)進(jìn)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).
