反射镜 4是为可调整位置的镜面， 该镜面的形成， 可经由镀膜或其他方式为之， 为使其具可调整的功能， 因此， 其得具一转轴 4 1， 如图所示， 此反射镜 4具有两个 稳态静止位置， 其可为如 4 5度角的外张， 唯亦可为平贴或垂直状态（虚线所示）， 当 其为如 4 5度角的外张时， 则会对光源发出的光形成反射作用， 将的反射至再反射镜 再反射镜 5是为二次反射之用， 基本上， 其是为与前述可调整反射镜 4为异向的 斜外向外张， 其目的在于将前述可调整反射镜 4反射投射的光线， 再为反射并为转向， 而且， 此再反射镜 5可为如预设的角度而为固定设置， 其可为平面反射镜亦可为直角 棱镜而利用内部全反射进行反射。
第二导光件 6是设于前述第一导光件 3的一侧， 并为再反射镜 5射出的方向上， 其内侧具一反射件 6 1， 外侧则具一散射件 6 2， 而中央则包夹一楔形导光件 6 3， 该反射件 6 1及楔形导光件 6 3是为已知构件， 在液晶电视、 液晶电脑显示器中广为 应用， 容不详述。 第一导光件 3与第二导先件 6， 实际上为一整体的结构， 在外观上 是一独立灯具整体。
请配合图 1， 当本发明起动光源 1时， 则光线往上投射， 并经第一导光件 3投射， 是以， 光线向上有如火炬式灯的照明效果， 灯光经天花板反射而成为间接照明， 如再 经过聚光件 2的反射， 则可增加其功效， 唯当将可调整反射镜 4外张时， 则由于投射 光线为遮断， 故并无向上的光线投射， 且光线会经由该可调整反射镜 4为反射， 并投 射至再反射镜 5， 而后进入第二导光件 6， 经反射强化设施 6 1、 6 3向侧方反射， 而自散射件 6 2为侧向输出， 成为柔和的光线泛出。 如此向上的灯光照明功能改变为 侧向的面或线形照明功能。
请再参阅图 2， 本发明的可调整反射镜 4可置于光源 1与第一导光件 3的间， 且 再反射镜 5则置于可调整反射镜 4之侧， 其倾角固定为可将光导入第二导光件 6的应 反射位置， 则当可调整反射镜 4随转轴 4 1外张时， 则可将光反射至再反射镜 5， 经 再反射镜 5将光线导入第二导光件 6中， 再经 6 1、 6 2、 6 3等装置的作用， 而为 侧向光线投射， 唯当可调整反射镜 4下翻成不干涉光线状态时， 如虚线所示， 则光源 1的光线可经由第一导光件 3为向上投射而自端处射出。
图 2中的再反射镜 5， 因其相对于光源与第一导光件的位置， 与图 1不同， 因此 倾斜方向是与可调整第一反射镜 4外张时的位置平行。
图 3为依据本发明设计构思的另一实施方案， 图中的第一导光件 3与第二导光件
6实际上共用相同空间， 共构为一柱体。 当光线由光源向上发射时， 先进入由空气为 介质的第一导光空腔 3， 当光线到达由光密较高， 折射是数较大的 P匿 A (压克力， 唯 不以此为限） 第二导光件 6的介面时， 有些光线将反射回来， 继续向上， 有些则进入 第二导光件 6的内部， 进入第二导光件 6的光线， 当继续前进而到达外缘的锯齿状介 面时， 将因外界是空气层而产生全反射折回， 全反射折回的光线将因为第二导光件 6 的内外缘， 两侧与空气接触的介面， 实际上均为平行面（第二导光件的设计规范）， 因 而继续进行内部全反射向上行进， 而不溢出， 直至由顶端射出。 当可关闭的反射镜 4 关闭后， 光线便只能向下反射， 向下反射的光线， 将先进入有如楔形的导光件 6， 当 此光线行进至与导光件 3的空气介面时将因全反射而折回， 当光线到达外缘的锯齿状 介面时， 部份光线将由锯齿的短边溢出， 而到达散射层 6 2 , 而向侧方射出。
由上所述第一导光件， 与第二导光件 6虽为共构在一相同空间之内， 但是由光行 方向的正逆而产生完全不同的照明效果， 由于反射镜 4的作用， 而达到不同照明功能 的目的。
图 3 - 1为局部放大示意图，由下向上的全反射光线终将到达另一与反射面平行的 另一反射面， 如虚线所示， 而被再全反射向上前进。 由上而下的光线有部份会由锯齿 边溢出。
当光线由图 3灯具的顶端射出时， 其为天花板反射式的间接照明， 当光线由柱体 四周溢出时， 则为空间照明， 形成两种不同的灯光气氛。
图 4， 所示为另一设计实施例， 平时可做为装饰灯照亮顶端的饰品， 但是当将光 罩 5掀起打开时， 其与光罩 5有机构连动 （图中未显示） 的反射镜 4亦同时关闭， 关 闭的反射镜 4， 将使经第一导光件空气腔 3 , 进入由 PMMA (压克力）制成的导光件 6， 而射向上方饰物的光线， 转而向下反射。 当此被反射而向下行迸的光线到达第二导光 件 6与第一导光件空气腔 3的介面时， 因为是由光密介质进入光疏介质且介面 6 设 计为 4 5度的倾斜角， 以使入射角大于全反射角而被内部全反射导向侧方， 向外射出 的光线将因已掀起的光罩 5的反射而向下转折， 照射桌面， 以供阅读等。
当光罩 5折回后，如虚线所示位置，反射镜 4将同时连动幵启（连动装置未显示）, 光线便可继续向上前进而照亮饰品。
图 3及图 4中的可启闭的反射镜装置， 可为如图 7 - 1所示的掀合式， 图 7 - 2所 示的栅栏式， 图 7 - 3所示的光圈式， 图 7 - 4所示的胡蝶叶式等， 唯不限此列举。
图 5所示为图 3所示的实施例的变化， 以显示本发明设计构思极富弹性的多元应 用。 当反射镜开启， 而使光线能继续向上前进时， 光线将经由光纤束导向光纤束的末 端， 而为局部重点照明灯具， 若是将反射镜 4关闭， 则光线由柱体四周溢射而出。 而 为空间环境照明。 光纤束外围的螺旋状弹簧是为了支撑与调整而设， 由于仅有光线进 入此光纤束而无电线， 此鹅颈状导光装置尚可设计为可 3 6 Q度旋转。
上述图 1及图 2所呈现的实施例， 为利用可调整位置的反射镜， 将位置固定的光 源的光线， 导入另一导光件的中， 而完成不同的照明效果。
图 3、 图 4所呈现的实施例则为用可开启或关闭的反射镜让光线通过或逆转返回 进入不对称的光导件中利用光行进方向不同， 而产生不同的照明效果。 基本上均是利 用反射镜使光线进入特性不同的光导的中而产生不同的照明效果。
使用者亦可以将镜面固定而由移动第一导光件而改变其与固定镜面的相对关系， 从而将第一导光件射出的光线导入第二导光件， 如图 6所示。
图 6为本发明设计构思的另一实施例。
图 6 - 1的第一导光件 3为可收折或掀起拉出的装置， 当其为如图 6 - 1的收折位 置时， 光线经固定的第一反射镜 4及固定的第二反射镜 5进入第二导光件 6， 经 6 1、 6 2、 6 3等光学设施而由第二导光件 6的侧方溢射而出， 当第一导光件 3被拉出时， 如图 6 - 2所显示， 则光线由第一导光件 3的底端射出而可供如阅读之用。
此一设计适合作为床头阅读灯或壁灯之用。当拉出时可供作阅读之用， 当收折时， 则光线射向侧方壁面或床头而成为侧光的空间照明。
图 6 - 3所示则为图 6 - 1所示实施例的对称造型。
当第一导光件在收折位置时，光线由两侧对称溢射而出作为壁灯时较为对称美观。 当拉出时则成为向下或向上 （倒置装设） 的洗墙式壁灯， 应用极富弹性。
图 6 _ 4为第二导光件置于第一导件后侧的实施例，当光线经反射镜反射而射入第 二导光件 6之后， 由图中 6 1、 6 2、 6 3等光学配备， 将光线投射向前方。 此实施 例的第一导光件 3为透明材质如压克力构成， 投向前方的散射光线将可穿过此透明的 第一导光件而呈面状照明。
由上所述， 经由本发明的实施， 其可使灯具具有两种或以上的功效， 且其在外表 上， 呈现无法预测或感知的惊奇感， 堪称为灯具的一大突破。
本发明所揭示的， 乃较佳实施例， 凡是局部的变更或修饰而源于本发明的技术构 思而为熟习该项技术的人所易于推知的， 俱不脱本发明的专利权范畴。
