元器件交易网讯3月28日消息，据外媒报道，飞利浦推出一款概念LED灯，不仅通过以太网供电还能感知区域内人员动作、环境温度等信息。

　　飞利浦最新概念LED灯采用以太网供电，输出光的同时还会通过传感器收集信息，且灯具之间可以互通信息。灯具中的动作传感器可以记录区域中员工的情况，温度传感器可以反馈当前温度。管理者可以实时监控办公室情况，或通过智能机应用调整照明、加热情况以减少水电费，但用以太网取代传统布线花费较高。

　　安装成本方面，相较传统布线飞利浦以太网供电（PoE）报价要低50%，对于有翻新办公室需求的管理者来说是个值得考虑的选择。（元器件交易网毛毛 译）

　　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."
