本发明的一些实施例将详细描述如下。 然而, 除了如下描述外, 本发 明还可以广泛地在其他的实施例施行, 且本发明的范围并不受实施例的限 定, 其以之后的专利范围为准。 再者, 为提供更清楚的描述及更易理解本 发明, 图式内各部分并没有依照其相对尺寸绘图, 某些尺寸与其他相关尺 度相比已经被夸张; 不相关的细节部分也未完全绘出, 以求图式的简洁。
图 1为本发明的发光二极管灯 100的实施结构, 包括: 基板 10 , 具有 第一表面 11及第二表面 12; 发光二极管模块 20, 其是设置于前述第一表 面 11 ; 灯罩 30 , 具有内部空间 31用于容纳前述基板 10; 电气连接部 40, 其是与前述灯罩 30连接, 用以与外部电源电气连接并提供前述发光二极管 模块 20发光所需电力; 散热构件 50 , 其是包覆于前述基板 10的第二表面 12侧的灯罩 30外; 及同步旋转控制装置 60。
在本结构中, 同步旋转控制装置 60是设置于前述灯罩 30的电气连接 部 40相对侧, 用以同步同向旋转灯罩 30内的基板 10及灯罩 30外的散热 构件 50, 而散热构件 50为一个散热罩。
在部分实施结构中, 基板 10的第二表面 12是可设置散热片 1 3 , 用以 将发光二极管模块 20工作所产生的热引导移除。
本发明所称的基板是用于设置发光二极管模块, 且因其应用, 发光二 极管是设置于基板的同一侧(即第一表面 11), 该基板可为铝基板、铜基板、 硅基板、 陶瓷基板或均温板。
本结构中的灯罩是用于容纳包覆发光二极管模块, 并得使发光二极管 工作时所产生的光穿透。 当可轻易理解的是, 本发明的特征不在于灯罩的 材质, 因此已知可应用于发光二极管灯的灯罩材质的材料, 包含但不限于 玻璃或塑胶, 皆为本发明可采。
本发明所称的电气连接部是用以自外部电源接收电力, 并经适当转换 或保护以提供发光二极管工作所需电压 /电流, 在一般的实施结构中, 电气 连接部 40包含灯头 41、 灯体 42或其结合物, 其中, 灯头 41的作用在于使 发光二极管灯得以固接于接座, 包括但不限于 E27或 E40, 在部份的实施结 构中, 灯头 41 内部是可容纳电子电路元件; 灯体 42的部分是视需要用于 容纳转换或保护所需的电子电路元件, 部分实施结构中灯体 42是由散热材 质所构成, 借此移除电子电路元件所生的热。
前述转换或保护的电子电路元件包括但不限于整流模块、 驱动模块、 调光模块、 限流模块或其结合, 且所述电子电路元件是各自独立设置于前 述灯头 41中或灯体 42中或基板 10上或分配设置于三者中。
本发明的电气连接部提供前述发光二极管模块发光所需电力是通过导 线传电, 在此结构中, 导线是具有实质上可供挠曲的柔软度或足够的长度, 使灯罩 30内的基板 10与灯罩外的散热构件 50同步旋转时不会断毁, 在部 份实施结构中, 本发明的发光二极管灯具有定位装置, 使前述基板 10与灯 罩外的散热构件 50同步旋转限制于一个区间,避免前述导线过度扭转断毁, 该定位装置的作用亦可为固定完成同步旋转的基板 10与散热构件 50,使其 不再旋转。
在部分结构中, 电气连接部 40提供前述发光二极管模块发光所需电力 是通过接触传电或者无线供电模块, 接触导电是指基板延伸出的供电接点 与电气连接部 40的供电接点经过设计, 可在灯罩内的基板与灯罩外的散热 构件同步旋转时维持电气连接, 至于无线供电模块则是通过设置于基板上 的接收电力模块与设置于电气连接部的电力供应模块的交互作用达到电力 供应的效果。
本结构的特色在于散热构件的设置与使用, 借此用于移除前述基板因 发光二极管工作产生的热, 已知技术为使完成安装后的发光二极管灯的基 板发光面能向下, 是在灯罩与电气连接部接触区域设置旋转机构, 然此设 计仍仰赖电气连接部同时扮演散热的功能, 高温对设置于其中的电子电路 元件寿命影响甚巨。 本结构通过基板、 同步旋转控制装置及散热构件的固接, 将发光二极 管模块工作时产生的热传导出灯罩外至散热构件, 并通过散热构件材质与 结构的选用设计将热逸散至空气中, 亦即在体积与设置条件允许下, 散热 构件是可具有散热鳍片或散热孔来提升散热效率。
本结构在灯罩的相对于电气连接部之侧设置了同步旋转控制装置, 通 过例如同轴固接的设计使灯罩内的基板与灯罩外的散热构件得以进行热传 导, 此设计的优点有二: (一)发光二极管工作产生的热由散热构件部份移 除, 可避免传统由电气连接部进行散热所致电子电路元件受热所致寿命耗 损; 及 (二)散热构件的面积远较电气连接部大, 在散热效果上更佳。
进一步地, 本发明所称的散热构件得以具有延展性, 或者具有延展机 构, 得以在发光二极管灯设置于灯具并调整照明方向后, 将该延展部或延 展机构作动, 使散热构件可以与灯具或周围物件接触, 让热进一步由散热 构件以接触传导至发光二极管灯以外的物体上, 特别是当本发明的发光二 极管灯为高功率应用(例如路灯用)时, 热可以传导至路灯灯具本体, 使热 逸散至空气的效果更佳。
参阅图 2, 在部分的实施结构中, 本发明的发光二极管灯 200, 其是进 一步包括风扇 70, 该风扇 70是设置于前述同步旋转控制装置 60上或散热 构件 50上或基板的第二表面 12 , 并且与前述电气连接部 40电气连结。 风 扇 70的运作可使风扇附近的空气产生流动, 提升散热效率。 以图 2为例, 该风扇 70是可使前述灯罩 30内的空气流动, 借此提高导热与散热效率。
本发明所称的同步旋转控制装置是用于同步旋转基板与散热构件, 使 横接的发光二极管灯中基板的发光面得以朝向目标方向, 而散热构件则可 同步移动至基板的非发光面一侧。 在具体实施结构中同步旋转控制装置为 同轴旋钮, 前述基板与散热构件是固接于该同轴旋钮的轴上, 转动旋钮时, 即可达到基板与散热构件的同步旋转。
更进一步地, 本发明另一结构的发光二极管灯 300是如图 3所示, 在 本结构中, 灯罩 30是与散热构件 50共同形成一个内部空间 31, 用以容纳 前述基板 10, 此时基板 10的第一表面 11是在灯罩 30侧, 第二表面 12是 处于散热构件 50侧, 在此结构中, 同步旋转控制装置 60设置于灯罩 30与 散热构件 50结合物与电气连接部 40间, 该同步旋转控制装置 60是可同步 同向旋转灯罩 30、 散热构件 50及基板 10。
在上述结构中, 由于发光二极管模块 20工作时产生的热是通过与基板 10及散热构件 50固接的同步旋转控制装置 60进行热传导, 进而由散热构 件 50将热逸散至空气中。 然而在部份的结构中, 同步旋转控制装置 60与 电气连接部 40间系可进一步包括隔热部, 该隔热部是可为具有实质隔热效 果的空间, 或者是具有隔热效果, 由隔热材料形成的隔热构件, 使发光二 极管模块 20 工作时产生的热得以完全或大部分地不会传导到电气连接部 40, 而是由同步旋转控制装置 60传导致散热构件 50将热逸散至空气中。
在本结构中, 并不排除于灯罩 30与散热构件 50结合物的电气连接部 40相对侧具有导热件 51, 该导热件 51是与基板 10及散热构件 50固接, 借此将发光二极管模块 20工作时产生的热以基板 10、 导热件 51及散热构 件 50的顺序进行热传导并逸散至空气中, 减少由同步旋转控制装置 60进 行热传导时, 热能传导至电气连接部 40的状况。
请参阅图 4, 其举例说明了本发明的又一结构,发光二极管灯 400的结 构是近似于图 3的结构, 但基板 10直接与灯罩 30共同形成一个内部空间 31 , 该内部空间 31是位于第一表面 11侧, 发光二极管模块 20工作时产生 的光穿过内部空间 31及灯罩 30向外发散, 而散热构件 50则可直接特化为 例如散热鳍片的构造而设置于基板 10的第二表面 12上, 直接将发光二极 管模块 20工作时产生的热由基板 10及散热构件 50逸散至空气中。
以上所述, 仅是本发明的较佳实施例而已, 并非对本发明做任何形式 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做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 例所做的任何简单修改、 等同变化与修饰, 均仍属于本发明技术方案的范 围内。
