技术领域
本发明涉及无线电力供应,尤其涉及感应供电装置。
背景技术
多年来,感应电力传递的原理已是众所周知。由于互感,电力就被从电源电路中的初级线圈(或简称“初级”)无线传递至次级电路中的次级线圈(“或简称“次级”)。次级电路与诸如灯、马达、充电器或任何其它供电装置。无线连接与常规硬件连接相比提供了许多优点。无线连接可以减少发生震动的机率,并且可以在供电电路与次级电路之间提供比较高水平的电绝缘,电感耦合还使得消费者更容易地更换有限使用寿命的部件。例如,在照明装置中,感应供电灯组件可以在不需要进行直接电连接的情况下容易地进行更换。这不仅使得过程更易于执行,而且限制了受到电击影响的风险。
然而,使用感应电力传递多半被限定于适当应用,例如用于潮湿环境中的连接。感应电力传递的用途有限主要是由于电力传递效率的问题。为了改进电感耦合的效率,通常是仔细设计初级、次级线圈的构型与布置方式。初级、次级线圈通常放置于紧密配合的部件内,其中初级与次级线圈之间间隙最小。例如,初级通常放置于限定了中央开口的底座内,而次级通常放置于在底座的中央开口内紧密配合的圆柱形部件内。这种及其它常规构造设计成用于在初级线圈与次级线圈之间提供接近同轴和沿径向的对齐方式。若干专利的特定实例反应了用于提供初级与次级线圈之间的固定、预定物理关系的常规途径,这些实例包括:授予Hutchisson等人的美国专利5,264,997,其公开了一种带有同轴且互相紧密配合的初级与次级线圈的感应灯;授予Mceachern等人的美国专利5,536,979,其公开了一种感应充电装置,其中待充电的装置在托架内紧密配合以便使得线圈位于固定、预定关系中;授予Tamura等人的美国专利No.5,949,155,其公开了一种其中相邻感应线圈设定于固定关系中的电动剃刀;授予VanLerberghe等人的美国专利5,952,814,其公开了一种电话用感应充电器,其中初级与次级线圈之间的物理关系固定;以及授予Brockman等人的美国专利6,028,413,其公开了一种具有用于确保感应线圈之间的精确、预定对齐的机械导向器的充电装置。在常规实践中,在初级与次级线圈之间提供精确对齐就对感应供电装置的总体设计和适应性产生明显限制。另外,在常规感应系统中,对用于驱动初级线圈的电源电路及以感应方式接收来自初级的电力的次级电路进行设计并且仔细地调整以便使其彼此相配从而使得电感耦合的效率实现最大化。这也对感应供电装置的总体设计和适应性产生明显限制。
发明内容
本发明可以克服上述问题,其中感应供电装置带有用于改变初级与次级之间相对位置以便控制供向负载的电力量的机构。在一个实施例中,本发明包括于可变暗灯组件中,其中初级安装于灯座上而次级安装于灯组件上。通过调节灯组件与灯座之间的距离可以对灯的亮度进行控制。
在第二实施例中,本发明包括于可变暗灯组件中,其中通过改变初级与次级之间的相对角度方位可以对灯的亮度进行控制。在这个实施例中,初级通常为环形而次级可绕枢轴转动地安装于环内。灯组件包括机械调光器,其绕着初级或次级转动以便改变它们的相对角度方位。相对角度方位的变化就改变了传递至次级的电力量,从而改变灯的亮度。
在另一个实施例中,本发明包括于具有一个或多个灯的风铃中,其中这些灯根据铃的运动情况而改变亮度。在这个实施例中,多个铃组件悬挂于初级线圈内,其中每个铃组件可以单独运动。每个铃组件包括在初级的磁场内放置于其上端的次级。当风吹动时,铃组件相对于初级摆动,从而改变位于初级的磁场内的次级线圈的位置与方位。这就使得风铃的亮度响应风的情况而改变。
在另一个实施例中,本发明提供了一种无限可调式电源,以便用于需要调节供向装置的电力量值的供电装置。电源包括置于电源与负载之间的电感耦合。电感耦合包括初级与次级。无限可调式电源还包括用于有选择地改变初级与次级之间相对位置如距离或角度方位的调节机构。调节机构可以调节耦合系数,从而调节次级中所感应并且供向负载的电力的量值。
在第二方面中,本发明的目的在于感应电源站,其能够向多个相对于初级处于任意位置与任意方位的感应供电装置提供电力。感应电源站通常包括绕着插座设置的单个初级,该插座能够接收随意放置的感应供电装置。电源电路包括用于根据出现于插座中的感应供电装置的情况来调节供向初级的电力的电路系统。在一个实施例中,插座为碟状、碗状或类似结构,其中可以放置一个或多个灯组件以便提供照明。每个灯组件包括以感应方式接收来自初级的电力的次级。通过改变放置于插座中的灯组件的数量以及通过在插座内移动灯组件可以对光的亮度进行控制。
在第三方面中,本发明提供了带有多个按照不同方位设置的线圈的次级。多个线圈使得次级在相对于初级按照不同方位放置时能够有效地接受电力。在一个实施例中,带有多个线圈的次级包括于感应供电灯中。灯组件在按照不同方位放置于初级的磁场内时可以接受最大感应电力。在另一个实施例中,灯组件包括多个线圈,每个线圈均电连接于不同的光源上,例如不同颜色的光源。通过调节灯组件的方位,所发出光的颜色可以通过改变分离式光源的相应亮度而改变。
通过阅读关于优选实施例和附图的详细描述,本发明所属领域的普通技术人员将会容易地理解本发明的这些及其它目的、优点及特征。

具体实施方式
本发明的目的在于改进感应供电装置。在第一方面中,本发明提供了电感耦合,其中可以有选择地改变初级线圈(“初级”)和次级线圈(“次级”)之间的相对位置以便可以控制传递至次级从而传递至感应供电装置的电力量。例如,结合各种灯构型对本发明的这个方面进行了描述,以便容许控制光源的亮度。还结合其它供电装置对本发明的这个方面进行了描述,其中需要控制供向感应供电装置的电力量。在第二方面中,本发明的目的在于感应电源站。在这个方面中,本发明提供了用于以任意位置和任意方位接受一个或多个感应供电装置的插座。在根据这个方面的一个实施例中,次级包括按照不同方位设置的多个线圈,以便使得在初级与次级之间没有精确对准的情况下,在次级中可以更有效地感应电力。在一个实施例中,次级包括沿着笛卡儿坐标系的x、y、和z轴线方向的三个线圈,以便可以在次级中感应电力而与次级相对于初级的角度方位无关。
图1中示出了根据本发明一个实施例的感应供电台灯10。台灯10通常包括底座12、灯组件14以及机械调光器16(参看图3)。底座12包括用于驱动初级20的镇流器与电源电路18。灯组件14包括具有次级24的次级电路22,次级24由初级20而感应供电并且将电力应用于光源26上。机械调光器16包括运动连接于灯座12上的可动式臂28。初级20安装于臂28上,以便使得臂28的运动引起初级20的运动。灯组件14悬挂于灯座12上,其中次级24放置于由初级20所形成的电磁场内。臂28可以机械运动以便改变初级20相对于灯组件14(进而相对于次级24)的位置,从而改变初级20与次级24之间的耦合系数。耦合系数的变化就导致传递至灯组件14的电力的变化,最终导致光源26的亮度的变化。结合可变暗灯10对本发明的这个方面进行描述。然而,本发明非常适合用于实际上需要改变传递至次级电路20的电力量的应用情况中。例如,如以下更详细地描述,本发明可以用于对供向装置的电力量提供高达电源电路容量的无限可调式控制。
如上所述,所示实施例的台灯10通常包括底座12、灯组件14以及机械调光器16。底座12通常包括台座30、轴32以及初级外壳34。所示实施例的台座20通常为盘形,其直径尺寸足以为轴32和灯组件14提供稳定支承,内部空隙31适于接受电源电路18和部分机械调光器16。轴32从台座向上延伸以便容放灯组件14。在所示的实施例中,轴32略微为“?”形,以便从审美角度提供令人满意的外观。轴32在钩36或者其它配置成用于接受灯组件14的环8的连接元件中终止于其上端。初级外壳34通常为环形并且中空以便为初级20提供外壳。初级外壳34安装于臂28上以便支承初级20处于通常环绕着灯组件14的次级外壳25的位置中。所示的台座30和轴32带有所需的美感外观。本发明容易适用于同各种设计的灯一起使用。相应地,所示底座12的设计与构型不应当被理解成对本发明的限制。电源电路18可以是常规型感应电源电路,然而在一个实施例中,电源电路18包括一种共振寻找式镇流器,例如2002年9月18日提交的名为“电感耦合式镇流器电路”的美国系列申请No.10/246,155中所公开的镇流器,并且本文中将其引入作为参考。在所示的实施例中,电源电路18的原理部件容放于台座30中的空隙31内,例如图3中所示。然而,电源电路18中部件的位置可以基本根据灯的设计与所需美感情况而在应用中不同。例如,电源电路18的原理部件可以替代地放置于台座30之中或之上的其它位置,或者可以放置于轴32之中或之上。根据另一种替代方案,电源电路18中的某些或所有部件可以集成灯10所用的壁式插座(未示出)。在所示的实施例中,初级通常为环形并且安装于通常为环形的初级外壳34内。初级外壳34限定了中央开口35,该开口35具有足够的尺寸以便容放灯组件的至少一部分。初级20(以及初级外壳34)的尺寸、形状及方位可以部分根据灯或其它感应装置的特定设计特性而在应用中不同。在所述的实施例中,初级20的内径为1.25英寸,并且包括50匝沿圆周方向绕着基本为常规型的塑料线圈架33缠绕的导线63。导线63可以是直型26轨距的导线。另外,在这个特定实施例中,上述参考的专利申请中电容器271、272的值为66nF。
灯组件14通常包括由次级电路22(参看图4和5)供电的光源26,如白炽灯。在这个实施例中,对光源26进行定制以便提供所需的美感外观。所形成的光源26的上端用于限定小环28,其容许光源26从限定于轴32端部的钩36上悬挂。所示实施例中定制形成的灯只是用于示例说明,光源26可以根据需要而在应用中不同。根据定制形成的灯的替代型方案,灯组件14可以包括常规型灯(未示出),其包含于设计成用于提供所需美感外观的外壳(未示出)内。例如,定制形成的光源26可以由标准白炽灯光源所代替,这种光源安装于华丽且在审美角度令人满意的外壳内。在这种替代实施例中,还可以将次级电路22封装于外壳内。
如上所述,灯组件14包括为灯26提供电力的次级电路22。次级电路22包括由初级20以感应方式驱动的次级24。图5中示出了次级电路的示意图。在这个实施例中,光源26为定制形成的30瓦白炽灯。光源26与次级24串联电连接,在需要的情况下与电容器60串联电连接。在这个实施例中,次级24的直径为0.25英寸,并且包括24匝沿圆周方向绕着基本为常规型的塑料线圈架62缠绕的导线64。导线64可以是直型26轨距的导线。任选的电容器60用于通过偏移次即24的感应系数而改进次级电路22的功率因数,如美国系列申请No.10/133,860中更详细地描述,其中该申请在2002年4月26日提交,名为“感应供电灯组件”,在本文中将其引入作为参考。在这个特定实施例中,电容器60包括33nF电容。包括次级24与电容器60的次级电路22的特性可以基本根据光源与电源的情况而在应用中不同。实际上,如上所述,在一些应用情况下可以任选电容器60并且将其去除。尽管这个实施例包括白炽灯光源26,但是替代地,本发明可以基本包括任何其它电磁辐射发射装置,例如气体放电灯或发光二极管。
如上所述,台灯10带有用于控制光源26亮度的机械调光器16。在所示的实施例中,机械调光器16包括于底座12与轴32中以便使得初级外壳34(进而使得初级20)垂直运动并且改变初级20与次级24之间的物理距离。如所示,初级外壳34安装于可动式臂28上。在这个实施例中,灯座12可以包括用于控制机械调光器16的刻度盘66a(参看图7)、滑块66b(参看图8)或旋转式顶部66c(参看图9)。根据常规机械原理,齿条-蜗杆式组件将刻度盘66a、滑块66b或旋转式顶部66c的旋转运动转换成初级20的垂直运动。更具体而言,刻度盘66a、滑块66b或旋转式顶部66c的运动使得蜗轮74转动,其中蜗轮74可转动地固定于灯座12或轴32内。在所示的实施例中,刻度盘66a通过正齿轮68连接于蜗轮74上。因此,刻度盘66a的旋转运动使得正齿轮68并最终使得蜗轮74发生旋转运动。蜗轮74的运动又使得齿条72进而使得初级20发生垂直线性运动。可能在图6中看得最为清楚,齿条72包括纵向狭槽73,它们与轴32内部上的相应肋(未示出)互相配合。这种界面容许齿条72在轴32内垂直运动。由于蜗轮组件的不可逆特性(即蜗轮74可以移动齿条72,但是齿条72不可以转动蜗轮74),其提供了“自锁”式机械调光器16。从电源电路18引至初级外壳34的电引线(未示出)足够松弛从而容许进行所需范围的运动。替代地,可以提供滑动触点(未示出)以便在机械调光器16的整个运动范围内保持电源电路18与初级20之间的电连接。
图10中示出了替代型机械调光器80。在这种替代实施例中,臂82的内端包括螺母84,可运动地安装于螺杆86上。臂82的高度通过转动螺杆86进行调节,这就使得螺母84沿杆86的轴上下运动。杆86可以基本上使用任意类型的控制如刻度盘66a、滑块66b或旋转式顶部66c来转动。如同上述的齿条-蜗轮实施例一样,可以提供松弛的电引线、滑动触点或其它类似机构以便保持臂82的整个所需运动范围的电连接。
替代地,机械调光器可以配置成用于使得灯组件14相对于初级20运动。由于可以简化系统的电构型,所以在一些应用优选的可以是这种替代方案。更具体而言,由于电源电路18与初级20之间不发生相对运动,所以在没有任何用于相对运动的调节设备(例如松弛的电引线或滑动触点)的情况下,导线或其它电连接可以直接从电源电路18到达初级20。另外,由于灯组件14为自给型,所以就不需要使得电连接到达灯组件14。在根据这种替代方案进行制造的台灯10’的一个实施例中,轴32’包括多个能够接受灯组件14’的凹口40a-c’(参看图11a-b和12)。在这个实施例中,灯组件14’的上端带有能够适配于凹口40a-c’的加大环38’。如所述,灯组件14’可以从不同的凹口40a-c’悬挂以便改变次级外壳25’相对于初级外壳34’的位置。这样又改变了灯组件14’的亮度。在替代型台灯10”的第二实施例中,轴32”由挠性材料制成,其能够弯曲从而改变灯组件14”相对于初级外壳34”的位置,进而改变次级相对于初级的位置。在一些应用情况下,挠性轴32”可以具有少许或没有弹性从而使在受到作用时保持处于被弯成的任何位置中。在其它应用情况下,挠性轴32”可能具有弹性从而就需要一种机构以便将轴32”保持于所需位置。在图13-16所示的这种应用情况的一个实施例中,砝码42”装配于轴32”上并且可以沿着轴32”运动以便设定并保持轴32”处于所需弯曲状态(参看图13和16)。在一个实施例中,砝码42”装配于轴32”上并且包括基本为常规型、弹簧承载的接线夹50”,其中该接线夹50”有选择地将砝码42”锁定于轴32”上的适当位置处。在操作中,弹簧52”使得接线夹50”在轴32”上偏置成接线位置。为了使得砝码运动,克服弹簧52”的偏置而将接线夹50”推至松脱位置,在该位置中接线夹50”沿着轴32”自由滑动。在台灯10’”的第三实施例中,平衡组件44’”用于设定灯组件14’”的位置。在这个实施例中,轴32’”优选地为中空轴,其限定了用于容纳平衡组件44’”的内部空间(未示出)。灯组件14’”通过缆线48’”而从轴32’”悬挂。缆线48’”延伸穿过轴32’”中的内部空间并且固定于平衡组件44’”上。环40’”安装于缆线48’”的自由端以便于灯组件环38’”互相连接。在图18中看得最为清楚,平衡组件44通常包括弹簧50’”(或其它偏置机构),其中弹簧的张力使得灯组件14’”的重量偏移。平衡组件44还包括一对牢固地夹住缆线48’”的辊子52a-b’”。辊子52a-b’”与Bellville垫圈54a-b’”装配在一起以便提供将缆线48’”限制于给定位置中的限制性制动(参看图19)。通过使得灯组件14’”的重量偏移,平衡组件44就将灯组件14’”保持于使用者所选定的位置中。这样就容许使用者通过升高或降低灯组件14’”来设定灯组件14’”的亮度。替代地,弹簧50’”可以由重量与灯组件14近乎相同的配重(未示出)来代替。
在另一个替代实施例中(未示出),机械调光器可以包括用于使得灯组件内的次级进行运动而非使得整个灯组件运动的机构。例如,灯组件可以包括次级,该以沿着固定轴滑动运动的方式进行安装从而使得使用者可以沿着轴上下滑动次级以便对灯组件(未示出)的亮度进行控制。替代地,次级可以转动方式安装于次级外壳内如通过将次级安装于球接头(未示出)上,以便使得次级的角度方位发生变化。按钮或手柄(未示出)可以穿过次级外壳中的狭槽伸出以便于线性或角运动。替代地,机械调光器可以包括使得初级在初级外壳内运动的类似机构(未示出)。
图20-22中示出了一种替代型感应供电灯100。在这个实施例中,对供向次级部件的电力量进行控制,通过改变次级124相对于初级120的相对角度方位。台灯100通常包括台座130、安装于台座130上的轴132以及可绕枢轴转动地安装于轴132上的臂133。在一个实施例中,光源126位于朝向臂133的一端,而配重150的位置朝向另一端。优选地,电源电路基本包含于台座130和轴132内,并且包括在环形初级外壳134内朝向轴132顶部安装的初级120。初级外壳134可以由注模的半部134a-b组装而成。支承件140从轴132向上延伸至由初级外壳134所限定的中央开口中。支承件140限定了适于容放臂133的凹形托架142。臂133包括放置于臂133的重心处的球体146。球体146可以由注模的半部146a和146b组装而成,并且其外径与托架142的内径相应。相应地,通过将臂133搁在支承件140上就使得臂133安装于轴132上,其中球体146容放于托架142中。在需要的情况下,通过大大加重球体146就可以改善臂133的稳定性。所示的连接容许臂133基本上沿所有方向绕枢轴运动。各种替代接合可以用于将臂133连接于轴132上。例如,标准标准球窝或标准万向节可以代替所示连接。在需要的情况下,可以使用只限制臂133运动的连接,例如只限制臂133的垂直运动或只限制其水平运动。
在操作中,臂133相对于轴132绕枢轴运动,从而使得球体146在托架142中发生滚动。当臂133进行运动时,次级124就在由初级120所形产生的磁场内绕枢轴转动。这就改变了耦合系数和光源126的亮度。次级124和初级120可以定向以便在臂133的所需位置处提供最亮的光线。例如,光源126可以在臂133处于大致水平时最亮并且随着臂133离开水平位置向上或向下运动而逐渐变暗。替代地,光源126可以随着臂133在水平位置之下向下运动而变得更亮。所提供的配重150用于平衡光源126的重量,从而保持臂133的相对位置,除非其受到作用力。
前述实施例的目的在于照明用途,其中光源的亮度由改变初级与次级之间相对位置的机构进行控制。然而,本发明并不限于照明用途。相反地,本发明非常适用于基本上任何需要控制供向装置的电力量的应用情况。在这个方面中,本发明提供了无限可调式感应电源。通过提供用于控制次级相对于初级的位置的机构,就可以对通过电感耦合供应的电力量进行控制。更具体而言,通过调节初级与次级之间的距离或初级与次级之间的角度方位,就可以在感应电源的范围内对电感耦合的耦合系数进行无限调节。在这个方面中,本发明不仅提供了无限可调式电源,而且还在电源与感应供电装置之间提供绝缘,从而提供了安全性优点。
结合图23中所示的变速风机200,对根据本发明的可调式电源进行更详细地描述。在所示的实施例中,风机200包括容放于基本为常规型的风机外壳282内的常规型电动马达280。电动马达280接收来自具有初级220和次级224的电源电路218的电力。次级224邻近初级220可运动地安装,以便使得次级224的运动可以用于有选择地改变电感耦合的耦合系数,然后又改变供向马达280的电力。例如,在所示的实施例中,次级224安装于调节杆290上。调节杆290相对于风机外壳可以进行内外运动,如箭头A所示,以便使得次级224相对于初级220进行运动。因此,调节次级224就可以用于有选择地控制风机200的速度。尽管这个实施例包括用于使得次级224运动的机构,但是替代地,通过提供用于使得初级220运动或者用于使得初级220与次级224都运动的机构也可以对耦合系数进行调节。如上所述,通过改变初级与次级之间的物理距离并且/或者通过改变初级与次级之间的相对角度方位都可以实现对耦合系数进行调节。
尽管结合可变速风机进行了描述,但是本发明的无限可调式电源非常适合用于其它需要可调式电源的应用情况中。例如,电源可以包括于电池充电器(未示出)中,其中通过调节初级与次级的相对位置而对充电的量值进行控制。根据另一个实例,电源可以包括于电钻(未示出)或其它电力工具中,其中通过有选择地改变初级与次级的相对位置而对供向电动马达的电力进行调节。
在另一个实施例中,台灯300带有灯组件314,该灯组件314可以按照不同的方位进行放置以改变光输出特性。在图24和25所示的实施例中,台灯300包括可以放置于垂直或反向位置中的灯组件314,其中这两个位置形成不同的照明效应。如所示,台灯300包括具有台座330、轴332以及初级外壳334的底座312。初级外壳334封装着初级320并提供了用于支承灯组件314的环形结构。在所示实施例中,透明板340安装于初级外壳334内以便容放灯组件314。板340限定了中央开口342以便灯组件314。在这个实施例中,灯组件314通常为“蛋形”,其具有一对放置于支承环360两侧的透光外壳部件。更具体而言,灯组件314包括透明外壳部分362和半透明外壳部分364。可以将分离式光源如白炽灯放置于每个外壳部分362和364内,或者可以提供单独光源,以便通过两个外壳部分362和364投射光线。外壳部分362和364各具有小于板340中的中央开口342内径的外径。因此,灯组件314可以悬挂在位于支承件360上的中央开口342内。
在使用中,通过按照不同方位将灯组件314放置于中央开口342中,就可以改变灯300所发出的光的特性。尤其是,将灯组件314与透明外壳部分362一起朝下放置,就使得台灯300向位于下方的表面投射出明亮、清楚的光,而背离该表面向上则投射出柔和、发散的光。将灯组件314倒转并且将其与半透明外壳部分364一起朝下放置,就使得台灯300向下在位于下方的表面上投射出柔和、发散的光,而背离该表面向上则投射出明亮、清楚的光。灯300所投射的光的各种变化还可以通过提供带有不同物理与光学特性的外壳部分362和364来实现。例如,两个外壳部分362和364可以由不同的有色材料制成,它们具有不同的尺寸或形状或者以不同的透镜特性形成,例如焦距、放大率以及扩散作用发生变化。替代地,灯300所投射的光的差异可以通过在外壳362和364内提供不同的光源来实现。例如,两种光源可能具有不同的功率,或者具有不同类型的灯。在一个实施例中,外壳362由透明玻璃或聚合物制成并且包含白色白炽灯泡,而外壳364由半透明玻璃或聚合物制成并且包含蓝色发光二极管。
在需要的情况下,还可以通过将灯组件314以不同位置放置于中央开口342中,从而改变初级与次级之间的物理距离。如果次级324与支承环360沿轴向对齐,那么次级324将会相对于初级320处于大致相同的位置,这与透明部分362或半透明部分364是否朝上无关。另一方面,如果次级线圈324从支承环360沿轴向偏移,那么初级320与次级324之间的物理距离将会根据灯组件314的方位情况而变化。次级324可以从支承环360沿两个方向偏移,这取决于所需光输出更多的位置。
又一方面,本发明包括于用于在现有螺旋座灯中工作的置换灯座400中。如图26中所示,灯座400包括外壳402,该外壳包括用于驱动初级420的电源电路418。在所示的实施例中,外壳402由围绕着电源电路418与初级420的两个注模式半部制成。外壳402还包括螺旋灯座404,与常规型白炽灯的现有螺旋灯座大致相同的。螺旋灯座404装配于外壳402的下部上,以便可以容易地将其拧入常规型灯插座(未示出)。电引线(未示出)从螺旋灯座404穿过外壳402中的相应开口延伸至电源电路418。外壳402限定了适于容放感应灯组件414的灯插座408。灯插座408可以包括机械调光器,其容许使用者以机械方式改变初级与次级之间的相对位置(参看图27和28)。然而,机械调光器并非必需,灯座408可以包括卡扣式组装件或其它常规组装件以便将灯组件414固定于灯座408内的固定位置上。在图27和28中所示的替代实施例中,灯座408’包括容许以机械方式改变灯组件414’位置的凸出物410a-b’。凸出物410a-b’与次级外壳403’的下表面上的相应凸出物412a-b’相互作用,如以下更详细地描述。凸出物410a-b’与412a-b’可以由螺纹或其它类似机构(未示出)所代替,以便以机械方式有选择地改变灯组件414’在插座408’内的深度。为了有助于将灯组件414保持于插座408内的所需位置中,插座408和次级外壳403配置成通过摩擦而互相配合。在这个实施例中,弹性o型环440可以绕着次级外壳403装配以便提供可靠的摩擦界面。优选地,O型环440位于环形凹槽(未示出)内以便有助于防止其沿外壳403上下滑动。O型环440可以装配于插座408中的环形凹槽(未示出)内。根据另一种替代方案,机械调光器可以包括用于使得外壳402内的初级420或次级外壳403内的次级424运动的机构。例如,每个线圈可以在相应外壳内沿着其轴线滑动运动以改变初级与次级之间的距离,或者每个线圈可以在相应外壳内绕枢轴转动地运动以改变初级与次级之间的角度方位。电源电路481可以同上述电源电路18大致相同,其中部件的值选择成与所需光源或光源的范围相配。
现在参看图26,灯组件414通常包括适于装配在灯插座408内的次级外壳403、包含于次级外壳425内的次级电路(未示出)以及从次级外壳425伸出的光源426。次级外壳425通常包括由次级424与次级电路的剩余部分(未示出)所围绕的两个注模式半部。如上所述,图27所示的替代实施例的次级外壳403’包括凸出物412a-b’,这些凸出物412a-b’位于其下表面上以便与灯座408的凸出物410a-b’相互作用。凸出物412a-b’可以没有或者由其它机械调光机构代替。优选地,次级电路与上述次级电路22大致相同,其中其部件的值选择成与所需光源426相应。
在替代实施例中,本发明包括于同时提供对风的听觉与视觉反应的感应供电风铃500(参看图29-31)中。通常,风铃500包括从吊环504悬挂的初级外壳512和多个从吊环514悬挂于初级外壳512的中心内的铃组件514a-d。初级外壳512通过导线502a-d或其它类似部件而从吊环504悬挂。吊环504配置成允许将风铃500悬挂于各种不同的位置处。在所示的实施例中,初级外壳512包括两个容放着初级520(参看图30)的注模式半部512a-b。电源电路(未示出)包含于壁式插座(未示出)上。电源电路581可以同上述电源电路18大致相同,其中部件的值选择成与所需光源或光源的范围相配。
每个铃组件514a-d通过相应导线506a-d悬挂于初级外壳512的中心内。分离式导线506a-d允许每个铃组件514a-d响应风的情况而自由运动。每个铃组件514a-d通常包括铃外壳530、光源526。次级电路522以及铃532。所示实施例的铃外壳530包括从相应导线506a-d悬挂的不透明上部外壳部分530a和安装于上部外壳部分530a下表面上的透明下部外壳部分530b。铃外壳530限定了用于包含次级电路522的内部空间,次级电路522包括次级524、光源526以及任何所需的电容器528。次级电路522容放于上部部分530a内,在此其大部分看不见。光源26从上部外壳部分530a向下延伸至下部外壳部分530b。铃532基本为常规铃,并且安装于每个铃外壳530的下端。因此,当铃组件514a-d随着风移动时,铃532彼此相撞以便产生声音。同时,当每个铃组件514a-d运动时,其次级524就朝向和背离初级520进行运动。次级524在初级520所产生的磁场内的运动就会改变供向光源526的电力量,进而改变光源526的亮度。更具体而言,当铃组件514a-d靠近初级520运动时,由初级520传递至次级524的电力量增加,光源526就变得更亮。相反地,当铃组件514a-d背离初级520运动时,传递至次级524的电力量减少,光源526就变得更暗。因此,风量增加就使得铃组件514a-d的运动增加,光源526亮度的波动就会增加。
在另一个方面中,本发明涉及感应电源站,其具有以感应方式向一个或多个感应供电装置提供电力的初级,每个均具有自身的次级线圈。在图32-35中所示的实施例中,感应电源站600通常包括由多条腿606a-c支承的电力插座602和存储插座608。初级620绕着电力插座602放置以便产生磁场,该磁场向放置于电力插座602内的任何感应装置650a-c提供感应电力。在所述的实施例中,初级620的直径为6.5英寸,并且包括50匝沿圆周方向绕着基本为常规型的塑料线圈架633缠绕的导线663。导线663可以是绞合线,这种绞合线包括八股按照每英寸一匝的方式缠绕的32轨距的绝缘导线,这样可以改进初级620的效率。初级620包含于初级外壳634内。现在参看图33,初级外壳634包括两个封装着初级620的环形半部634a和634b。
电力插座602用于以任意位置、任意方位容放多个感应装置,例如灯组件614a-b。在所示的实施例中,电力插座602为碗形,其由透明或半透明材料如玻璃或塑料制成。碗形电力插座602装配于初级外壳634内并由其支承。尽管所示的电力插座602为碗形,但是插座可以具有各种替代构造。例如,碗形插座602可以由可以放置感应供电装置的水平平面(未示出)代替,或者其可以由从此处可以悬挂感应供电装置的一个或多个环来代替。根据另一个实例,插座可以是垂直平面,该垂直平面邻近可以悬挂各种感应装置如感应供电壁灯或感应供电时钟的地方。
如上所述,所示的电源站600还包括例如通过螺钉或其它紧固件而安装于腿606a-c上的存储插座608。存储插座608提供了用于存储灯组件如灯组件614c以及其它未使用时的感应供电装置的位置。在这个实施例中,存储插座608为碗形以便与电力插座602的形状互补,并且安装于电力插座602下面的站600的腿606a-c与底座612的上方之间。存储插座的大小、形状、构型和位置可以根据需要而在应用中进行变化。替代地,可以没有存储插座608。
电源站600还包括向初级620供应电力的电源电路618。在所示的实施例中,电源电路618置于灯座612内。现在参看图34,灯座612通常包括封装着电源电路618的上部外壳612a和下部外壳612b。电源电路618包括由按钮692致动的电源开关690。按钮692向下延伸通过上部外壳612a中的相应孔694以便与开关690接合。按钮692可以为透明的,电源电路618可以包括一对电力指示LED696a-b,他们在电源接通时照亮按钮692。在这个实施例中,电源软线698穿透下部外壳612b并且电连接于电力输入插口699上以便提供通向电源电路618的AC电力。电引线(未示出)从电源电路618通过位于腿606a-c之一中的布线通道(未示出)延伸至初级620。优选地,电源电路618与上述电源电路18相同。该电源电路618能够监控供向初级620的电力,以便确定累积负载(例如,放置于电力插座602中的感应供电装置)的某些特性,而后根据所监控到的值对供向初级620的电力的特性进行调节。在一个实施例中,电源电路618监控供向初级620的电流并根据该电流的值对供向初级610的频率进行调节。
在所示的实施例中,感应供电装置为多个灯组件614a-c。可能在图35中看得最为清楚,每个灯组件614a-c一般包括封装着光源626a-d和次级电路622的灯外壳604。在这个实施例中,灯外壳604由两个玻璃或注模式塑料半部604a-b组装成,其中至少一个半部由透明或半透明材料制成。例如,这些半部604a-b通过盖环640以粘结或螺纹方式而互相连接。分离式o型环642a-b可以装配于盖环640与每个半部604a-b之间。次级电路622封装于灯外壳604内,并且通常包括与光源626a-d串联连接的次级624和任选电容器630。在所示的实施例中,光源包括多个LED626a-d。在这个实施例中,次级624的直径为2英寸,并且包括27匝沿圆周方向绕着大致为常规型的塑料线圈架662缠绕的26轨距的直型导线664。次级624的特性(例如:匝数、线圈直径、导线类型)和任选电容器630的特性(例如:电容值)选择成与光源626a-d和由初级620所供应的电力相应。
为了改善感应电源站的挠性,感应装置可以包括具有多个按照不同方位设置的线圈的次级。在只使用单个线圈的应用情况下,随意放置于电力插座内的装置可能将会位于大致平行于磁场定位的线圈中。在这种情况下,次级可能收不到足够的电力来用于从初级向装置供应电力。通过提供次级线圈设置结构,就显著增加至少一个线圈将会至少基本上与初级所产生的磁场的磁力线相交的可能性,所以使用多个线圈就解决了这一问题。例如,感应装置可以包括带有两个线圈的次级,这两个线圈互相成90度。利用这种构型,两个线圈中至少一个就可能跨过磁场的磁力线延伸并且接收来自初级的电力。分离式线圈的数量可以因应用情况不同而不同,例如,感应装置可以包括3、4、6或8个处于不同方位的线圈以便在各个方位改进效率。通过按照不同方位提供足够数量的线圈,感应装置就可以配置成用于接收来自初级的电力而与感应装置的方位无关。
在一个实施例中,感应供电装置包括次级670,次级670具有三个分离式线圈672a-c;一个分离式线圈沿着笛卡儿三维坐标系的x、y和z轴中的每一个。如图36中所示,三个线圈架660a-c提供用于容放三个线圈672a-c。三个线圈架660a-c的直径不同以便使得线圈架660a-c可以按照一个位于另一个之内的方式进行装配。假定次级所感应的电力与次级的直径成比例,那么使用不同尺寸的线圈架就可能使得供向每个次级的电力失衡。在需要平衡不同线圈672a-c所感应的电力的应用情况下,可以将附加的导线匝数加在较小的线圈架660b-c上,其中添加至每个较小线圈架上的附加匝数的准确数值主要取决于其尺寸大小。例如,如果最外部的次级672a包括七匝,可能就需要在中间次级672b上放入八匝,而在最内部的次级672c上放入九匝。替代地,可以提供球形线圈架(未示出),其中每个线圈按照所需位置、沿所需方位例如绕x、y和z轴绕着球形线圈架缠绕。这个实施例就减少了三个次级在直径方面的差异,从而改善了线圈的平衡情况。尽管结合感应供电灯组件614对带有多个线圈的次级进行了描述,但是带有多个线圈的次级基本可以包括于任何感应供电装置中以便在磁场内使得沿装置的各个方位的电力传递最大化。例如,蜂窝式电话(未示出)或个人数字助理(未示出)可以带有感应供电电池充电器,这种充电器具有单个线圈的次级如上述次级622或带有多个线圈如次级670。在这个实施例中,由于次级670能够获得足够的电力用于以任意方位对装置进行充电,所以具有带有多个线圈的次级的蜂窝式电话或个人数字助理可以随意放置于电力插座602内而无须关注其方位情况。
图38a-c示出了用于三线圈式次级670的三个实施例的电路图。图38a示出了用于提供来自三个分离式线圈672a-c的DC电力的电路680。如所示,三个线圈672a-c与负载并联连接,电容器674a-c串联连接于每个线圈672a-c与负载之间。在这个实施例中,每个电容器674a-c和每个二极管676a-c的值选择成用于为电路的负载侧提供谐振电路。这个电路680使用电容器将每个线圈内感应的电力组合起来以便提供与负载的谐振,而二极管674a-c对来自电路680的电压输出进行整流。替代地,可以从电路680中将二极管676a-c去除,以便向负载提供AC电力。
图38b示出了用于提供来自三个分离式线圈672a-c’的DC电力的半波整流电路680’。如所示,通过将二极管676a-f’串联连接于每个线圈672a-c’与负载之间,而使得这三个线圈672a-c’与负载并联连接。在这个实施例中,每个二极管676a-f’的值主要根据负载的特性来确定。另外,电容器674a-c’串联连接于线圈672a-c’的一侧与相应二极管676a-f’之间。每个电容器674a-c’的值也主要根据负载的特性来确定。这个电路680’使用电容器将每个线圈内感应的电力组合起来以便提供与负载的谐振,而二极管676a-c对来自电路680’的电压输出进行整流。
图38c示出了用于提供来自三个分离式线圈672a-c”的DC电力的全波整流电路680”。如所示,通过将二极管676a-l”串联连接于每个线圈672a-c”与负载之间,而使得这三个线圈672a-c”与负载并联连接。在这个实施例中,每个二极管676a-l”的值主要根据负载的特性来确定。另外,电容器674a-c”串联连接于线圈672a-c”的一侧与相应二极管676a-l”之间。每个电容器674a-c”的值主要根据负载的特性来确定。这三个电路680、680’和680”都执行提供DC电力的功能。电路680可能是成本最的低的设计,而电路680”对DC输出提供最好的控制,例如,与其它两个实施例相比,电路680”可能使得输出中的波动最小。
在使用中,所示的感应电源站600与伴随的灯组件614a-c提供了与众不同且从审美角度令人满意的光源。通过改变放置于插座602内的灯组件614a-c的数量,通过改变插座内每个灯组件614a-c的位置以及通过改变插座内的每个灯组件614a-c的方位就可以对系统所投射光的数量与特性进行调节。例如,可以将附加灯组件614a-c加入插座中以便增加系统所投射光的亮度。类似地,可以改变给定灯组件614a-c的位置或方位以便对特定灯组件614a-c的光输出进行控制。
在替代实施例中,灯组件614包括两个连接于分离式次级624a-b上的光源626a-b(参看图37)在这个实施例中,两个光源626a-b优选地为发光二极管,每个二极管均发出不同颜色的光。次级624a-b彼此成90度以便使得供向一个次级的电力与供向另一个次级的电力成反比。例如,通过转动灯组件614和电力插座602,就将一个次级移入与初级620所产生的磁场更直接相交的位置中,而另一个次级就被移动至与磁场更不直接相交的位置。因此,灯组件614可以在电力插座602内转动以便通过调节供向每个光源626a-b的电力量而有选择地控制灯组件614的颜色。例如,利用红与蓝光源,就可以使得灯组件614转动以便投射出范围从纯红至紫至纯蓝的光。在需要的情况下,装置可以带有3个分离式次级,这三个次级各互相成90度方位,例如沿笛卡儿三维坐标系的x、y和z轴。根据这种替代方案,每个次级都可以驱动分离式光源或者为分离式电装置供电。应当指出,通过比较来自每个次级的电压,就可以将三条轴线的构型用于计算装置的方位。在一些应用情况下,可能需要提供带有两组线圈的感应供电装置,其中第一组设定成用于为一个或多个装置提供电力,而第二组用于提供位置信息。图39a-d示出了用于各种多个次级电路的电路图。图39a示出了单一式三次级电路700,其中每个线圈702a-c连接于分离式负载上,所述负载如光源、三通道式位置计算电路的单一通道或其它感应供电装置。图39b示出了一种替代型电路710,其中电容器714a-c串联连接于每个次级712a-c与其相应负载之间。在这个实施例中,每个电容器714a-c的电容值主要根据相应负载与相应次级的感应系数来进行选择以便调整每个次级电路内的电力。图39c示出了一种替代型电路720,其中电容器724a-c与二极管726a-c串联连接于每个次级722a-c与其相应负载之间。该电路720提供限制性整流以便提供通向每个负载的分离式DC电力源。在这个实施例中,每个电容器724a-c和二极管726a-c的电容值主要根据相应负载与相应次级的感应系数来进行选择。图39d示出了一种替代型电路730,其中电容器734a-c与一对二极管736a-f串联连接于每个次级732a-c与其相应负载之间。该电路730提供半波整流以便提供通向每个负载的分离式DC电力源。在这个实施例中,每个电容器734a-c和二极管736a-c的电容值主要根据相应负载与相应次级的感应系数来进行选择。尽管并未示出,但是替代地,每个次级可以包括全波整流电路以便提供通向每个负载的分离式DC电力源。
尽管结合独特的灯构造对感应电源站600进行了示例说明,但是感应装置可以包括其它类型的感应供电装置。例如,蜂窝式电话、个人数字助理或其它类似装置可以包括配置成用于接收来自感应电源站的电力的感应供电电池充电器。在这种应用情况下,感应供电装置可以通过只需将其放置于电力插座内而进行充电。感应供电装置可以使用由次级供应的电力来直接为装置提供电力,而非只是为其再充电。例如,微型收音机、MP3音乐播放器或其它媒体播放器可以带有容许它们由电源站供电的感应次级电路。
上述描述为对本发明优选实施例的描述。在不背离附属权利要求所限定的本发明的精神和更广意义的情况下,可以作出各种替代与变化,它们应当根据包括等效原则的专利法的法则来进行理解。所涉及的例如使用冠词“一”、“一个”、“该”或“所述”而以单数形式所修饰的权利要求元件不应当理解成将元件限定为单数。
