　　元器件交易網訊3月28日消息，據外媒報道，飛利浦推出一款概念LED燈，不僅通過以太網供電還能感知區域內人員動作、環境溫度等信息。

　　飛利浦最新概念LED燈采用以太網供電，輸出光的同時還會通過傳感器收集信息，且燈具之間可以互通信息。燈具中的動作傳感器可以記錄區域中員工的情況，溫度傳感器可以反饋當前溫度。管理者可以實時監控辦公室情況，或通過智能機應用調整照明、加熱情況以減少水電費，但用以太網取代傳統布線花費較高。

　　安裝成本方面，相較傳統布線飛利浦以太網供電（PoE）報價要低50%，對于有翻新辦公室需求的管理者來說是個值得考慮的選擇。（元器件交易網毛毛 譯）

　　Get ready for a whole new generation ofconnected lightbulbs. Philips latest concept replaces an office's traditionalelectrical wiring with Ethernet, used to power LED bulbs and pass info to andfrom each lamp. Each fixture outputs light, but also collects information froma variety of sensors. A motion sensor can track the number of employees in agiven area, for example, while a thermometer can report back on the currenttemperature. Facility managers can track any section of the office in realtime,adjusting lighting and heating from a smartphone app to save on utilitieswhenever possible. Of course, as you'll need to replace traditional cablingwith Ethernet, the installation itself is sure to cost a pretty penny. Philipsquotes a 50-percent reduction in installation costs for PoE over traditionalwiring with new installations, however, so if you're planning to refurbish anoffice this is definitely an interesting option to consider.

　　Said Philips' Jeff Cassis, "The LEDlighting alone is 80% more efficient than conventional lighting. Personalcontrol of the lighting by employees actually increases efficiency as generallighting levels can be kept lower. The potential savings on a building’soperational costs will be significant, given that heating, cooling and lightingtogether account for 70% of a building’s energy usage."
