为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功 效, 以下结合附图及较佳实施例, 对依据本发明提出的一种可调光的发光 二极管灯具其具体实施方式、 结构、 特征及其功效, 详细说明如后。
请参阅图 1, 本发明所提供第一实施例的可调光的发光二极管灯具, 用以接收直流电源 100的电能后产生亮光, 且该直流电源 100具有正电线 路以及负电线路, 且该正电线路与该负电线路分别具有以金属制的轨道
1 01、 102。 该可调光的发光二极管灯具包含有主体 10、 遮罩 20、 透明镜片 25、 直流 /直流转换器 30以及发光二极管组 40。 其中:
该主体 1 0呈空心, 且该主体 10上具有导电部。 该导电部具有以导体 制成的第一端子 11以及第二端子 12 , 而该端子 11、 12之间呈断路。 于本 实施例中, 该第一端子 11与该第二端子 12 为钩状的金属片, 用以分别勾 设于该轨道 101与该轨道 102中。
该遮罩 20呈喇 p八状, 并具有开口 22, 且遮罩 20的内表面为可反光的 表面, 且该遮罩 20相反于该开口 22的一侧与该主体 10连接, 而使得该遮 罩 20位于该主体 10上相反于该端子 11、 12的一侧。 其中, 该遮罩 20至 少其中一部分可透光。
于本实施例中, 该透明镜片 25为塑胶材料制成的凹透镜, 且设于该遮 罩 20上, 并遮蔽该开口 22, 即该遮罩可透光的部分。 当然,在实际实施上, 该透明镜片 25亦可以依需求改为玻璃制成, 且亦可为凸透镜或平板镜片。 该直流 /直流转换器 30设于该主体 10中, 且与该导电部的该端子 11、 12电性连接, 以通过该端子 11、 12接收该直流电源传输至该导轨 101、 102 的电能, 并依据该直流电源的电能的电压(即该导轨 101、 102间的电位差) 转换输出对应的电流。 另外, 于本实施例中, 该直流 /直流转换器 30输出 的电流正比于该直流电源 100的电能的电压, 意即, 当该直流电源 100的 电能的电压越大, 该直流 /直流转换器 30输出的电流则越大。
该发光二极管组 40具有多个发光二极管, 设于该主体 10上而位于该 遮罩 20中, 且电性连接该直流 /直流转换器 30。 该发光二极管组 40用以持 续接收该直流 /直流转换器 30输出的电流, 以使所述多个发光二极管产生 亮光穿射过该开口 22 , 提供使用者照明的功能。 众所皆知的是, 发光二极 管的亮度与供给的电流呈正比关系, 换言之, 供给该发光二极管组 40的电 流越大时, 其产生的亮光的亮度则越大。 反之, 供给该发光二极管组 40的 电流越小时, 其产生的亮光的亮度则越小。
如此一来, 通过上述的设计, 配合可以调整电压的直流电源 100后, 便可有效地调整该直流 /直流转换器 30输出的电流, 进而达到调整该发光 二极管组 40产生的亮光亮度的目的。
值得一提的是, 通过该遮罩 20内表面可反射光线的设计, 更可将射向 该主体 10方向的光线反射至该开口 11的方向, 进而增加该可调光的发光 二极管灯具的照明效率。 另外, 该透明镜片 25为凹透镜的设计, 更可使自 该开口 22射出的亮光散射, 进而有效地增加该可调光的发光二极管灯具的 照明范围, 且亦能有效地保护装设于该遮罩 20中的发光二极管组 40。
另外, 除上述设计外, 请参阅图 2, 本发明第二较佳实施例的可调光 的发光二极管灯具更可具有改变照明色度的效果。 该可调光的发光二极管 灯具同样包含有主体 50、 遮罩 60、 透明镜片 65、 直流 /直流转换器 70以及 发光二极管组 80。 而与上述实施例不同之处在于, 该可调光的发光二极管 灯具所应用的直流电源 200 包含有第一正电线路、 第二正电线路以及负电 线路, 且该第一正电线路、 该第二正电线路以及该负电线路分别具有金属 制的轨道 201 - 203。 另外, 该第一正电线路(轨道 201)与该负电线路(轨道 202)之间具有第一电压, 而该第二正电线路(轨道 203)与该负电线路(轨道 202)之间则具有第二电压。 所以, 因应上述差异, 该主体 50的导电部则对 应具有呈勾状金属片的第一端子 51、 第二端子 52以及第三端子 53, 所述 多个端子 51 ~ 53之间同样呈断路, 且该第一端子 51与该轨道 201连接, 该第二端子 52与该轨道 202连接, 而该第三端子 53与该轨道 203连接。
该直流 /直流转换器 70同样设于该主体 50中,并与所述多个端子 51 - 53连接, 且依据该第一电压转换输出对应的第一电流, 以及依据该第二电 压转换输出对应的第二电流。
该发光二极管组 80 包含有多个第一发光二极管 81 以及多个第二发光 二极管 82 ,且所述多个第二发光二极管 82的光色不同于所述多个第一发光 二极管 82的光色, 举例来说, 该第一发光二极管 81的光色为冷光色系(如 白光、 蓝光等), 而该第二发光二极管 82 的光色为暖光色系 (如黄光、 红 光等)。 该发光二极管灯组 80设于该遮罩 60 中, 并与该直流 /直流转换器 50电性连接, 且该第一发光二极管 81接收该第一电流, 而该第二发光二极 管 82则接收该第二电流。
如此一来, 通过上述的灯具设计, 只要调整该直流电源 200 的该第一 电压与该第二电压, 便可有效地调整该直流 /直流转换器 70输出的第一电 流与该第二电流, 以分别改变所述多个第一发光二极管 81与所述多个第二 发光二极管 82产生的亮光的亮度, 进而达到调整该发光二极管组 80产生 的亮光色度的目的。
最后, 必须再次说明, 前述仅为本发明较佳实施例而已, 并不以使用 于轨道的灯具为限, 亦可为灯泡、 灯条等构造, 且于前揭实施例中所揭露 的构成元件, 仅为举例说明, 并非用来限制本案的范围, 其他等效元件的 替代或变化, 亦应为本案的申请专利范围所涵盖。
以上所述, 仅是本发明的较佳实施例而已, 并非对本发明作任何形式 上的限制, 虽然本发明已以较佳实施例揭露如上, 然而并非用以限定本发 明,任何熟悉本专业的技术人员, 在不脱离本发明技术方案范围内,当可利 用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例,但 凡是未脱离本发明技术方案的内容, 依据本发明的技术实质对以上实施例 所作的任何简单修改、 等同变化与修饰, 均仍属于本发明技术方案的范围 内。
