另一个展示性实施例的水龙头110在图11-图17中被示出为包括与以上详述的展示性水龙头10相似的许多部件。在以下描述中，展示性水龙头10与110之间的相似部件将用相同的附图标号来标识。
参考图11至13，展示性照明装置112可操作地联接到由水龙头主体(展示性地是输送流道114的悬臂部分117)限定的出口部分113上。更具体地，出口组件119由输送流道114的出口部分113支撑。出口组件119展示性地包括出口壳体120，该出口壳体包括限定了出水口18的第一部分122以及支撑照明装置112的第二部分124。出口壳体120可以由模制聚合物形成。
壳体120的第一部分122包括由倒钩配件126限定的入口。出水管23接纳配件126以便提供与内部流体室128的流体连通。常规的起泡器(未示出)可以由室128的下部部分接纳以便限定出水口18。
接纳室130被限定在壳体120的第二部分124与覆盖件132之间。覆盖件132包括诸如卡扣指状件134等联接器，以便将覆盖件132固定到壳体120上。照明装置112的上部部分被支撑在接纳室130内，而照明装置112的下部部分在输送流道114的悬臂部分117的下表面136的下方延伸。更具体地，基板或支撑件展示性地为印刷电路板(pcb)138，被联接在接纳室130内。如在此进一步详述的，电缆140在输送流道114的内部中延伸到水槽台板30(图1)的下方，以用于将印刷电路板138电联接到其他电气部件上。
参考图13和图16，控制器142、第一传感器(例如光传感器144)和第二传感器(例如声传感器146)可以被联接到印刷电路板138上。灯组件150可以包括光发射器70(例如，发光二极管)，这些光发射器被展示性地支撑在印刷电路板138的相对的右表面152a和左表面152b上。传感器144、146和光发射器70与控制器142展示性地通过形成在印刷电路板138上的导电迹线而电连通。半透明透镜或漫射器154被联接到印刷电路板138的下端上以便引导来自光发射器70的光。透镜154展示性地由半透明材料(例如，丙烯酸树脂或聚合物)形成。透镜154展示性地包括面向上的凹部156以便接纳光发射器70(图17)。展示性地，透镜154在输送流道114的悬臂部分117的下表面136下方延伸。同样地，从光发射器70发射的光展示性地从透镜154水平向外且竖直向下延伸(如图12中的隐藏线157所示)。
参考图13和图17，在透镜154的下表面中展示性地形成开口或凹部158，以便有助于将声音传输到声传感器146。为了防止水进入出口壳体120中，凹部158可以是(例如，具有大约0.010英寸的直径的)小通孔、或是盲凹部。
图18示出了联接到出口壳体120上的展示性管组件160。管组件160包括与第二管状部分164平行延伸的第一管状部分162。管组件160可以由共挤出聚合物形成，在截面上形成了“数字8”。展示性地，第一管状部分162限定了出水管23，而第二管状部分164接纳电缆140。
参考图19，控制器142可以控制灯组件28、150的光发射器70的操作。在一个展示性实施例中，手动输入开关166可以由使用者操作来启用和停用光发射器70。可替代地，接近度传感器168(诸如红外(IR)传感器和/或电容式传感器)可以检测水龙头10、10’、110附近的人的存在、并且响应于人的存在而启用光发射器70。可替代地，声传感器146(例如，麦克风)可以响应于检测到的声音而启用和/或停用光发射器70。声传感器146可以随时间比较音频测量值以便建立基准值来解决(即，过滤)背景噪声。
在另一个展示性实施例中，控制器142可以包括时钟或计时器170，该时钟或定时器在预选择的时刻和/或持续预选择的持续时间启用和停用光发射器70(例如，在首次将电力供应给控制器142之后启用8小时，随后停用16小时等)。
在其他展示性实施例中，水参数传感器172可以与控制器142通信。例如，水温传感器可以被配置用于检测供应到出水口18的水的温度并向控制器142提供信号。对检测到的水温的表示可以随后由光发射器70来提供。例如，当检测到的温度从冷到热升高时，光发射器70可以发射从蓝色转变成红色的光，并且当检测到的温度从热到冷下降时发射从红色转变成蓝色的光。
在某些展示性实施例中，光传感器144可以由印刷电路板138支撑并且与控制器142电连通，以便检测邻近水龙头10、10’、110的环境(例如，室内)光。展示性地，光传感器144可以包括被配置用于检测环境光的强度的光敏电阻器。在一个展示性实施例中，当如由光传感器144检测到的房间中的光低于存储在控制器142的存储器174中的预定值(例如，勒克斯)时，控制器142启用光发射器70。当如由光传感器144检测到的房间中的光至少与预定值(例如，勒克斯)一样大时，控制器142可以停用光发射器70。
在另一个展示性实施例中，一旦如由第一传感器(例如，光传感器144)检测到的房间中的光低于存储在控制器142的存储器174中的预定值(例如，勒克斯)时，那么第二传感器(例如，声传感器146和/或接近度传感器168)就被开启或启动(即，“唤醒”)。如果开启的声传感器146检测到至少与预定阈值一样大的声音，或者开启的接近度传感器168检测到使用者(例如，至少与预定阈值一样大的运动)，那么控制器142就启用光发射器70。一旦如由光传感器144检测到的房间中的光至少与预定值(例如，勒克斯)一样大，那么第二传感器(例如，声传感器146和/或接近度传感器168)就可以被禁用或关掉(即，进入“睡眠模式”)。当光传感器144检测到的光至少与预定值(例如，勒克斯)一样大时，或者当光发射器70已经被启用持续如由计时器170测得的预定时间(例如，2分钟)时，控制器142还可以停用光发射器70。以这种方式，通过在水龙头10、10’、110附近的环境光高于阈值时停用第二传感器146、168，节省了电力76(例如电池)。
以上所述仅为本发明示意性的具体实施方式，并非用以限定本发明的范围。任何本领域的技术人员，在不脱离本发明的构思和原则的前提下所作的等同变化与修改，均应属于本发明保护的范围。
