原标题：NXP JN516x无线MCU智能家居照明方案

　　nxp公司的智能家居照明方案采用基于NXP JN516x无线MCU的ZigBee光链接(ZLL)网络,具有无线IP连接,节能照明和待机功耗低(目前是150mW,以后要降到50mW)以及小型低成本等优点.

　　NXP’s GreenChip smart lighting solution brings together wireless IP connectivity, energy-efficient lighting and low standby power (150mW, roadmap down to 50mW) in a compact, low-cost solution, which enables new ways to control lights and manage energy consumption.

　　This Application Note provides a ZigBee Light Link (ZLL) wireless network solution which uses the NXP JN516x-EK001 Evaluation Kit. The demonstration allows the user to control ZLL Lighting devices from ZLL Controller devices. From the evaluation kit:

　　• the Lighting/Sensor Expansion Boards (DR1175) are used as ZLL Lighting devices

　　• the Remote Control Unit (DR1159) is used as a ZLL Controller device

　　The ZigBee Light Link (ZLL) network consists of a combination of ZLL Controller and ZLL Lighting devices.
