Abstract

一种全周光LED灯具，其由一灯座（11）、多根灯管（12）、多个自黏基板（13）、多个第一LED元件（14）、一承载板（16）、多个第二LED元件（18）、以及一透明罩体（19）所构成。该全周光LED灯具的瓦数平均分担至每一根灯管之上，由于该些第一LED元件是通过自黏基板而直接贴附于灯管内壁，因此，该些第一LED元件所产生的热亦可通过灯管而直接散至空气中；再者，该全周光LED灯具是采用分离示光源的设计，因此达到分散式散热的功效。

Description

全周光LED灯具 技术领域
本发明涉及节能灯具的技术领域，尤其涉及一种全周光LED灯具。
背景技术
电灯泡，即白炽灯，其发光方式是藉由通电的方式将设置于灯泡内的钨丝加热至白炽状态。通常，白炽灯的灯泡是由玻璃所制造，且钨丝是设置于玻璃灯泡所围成的真空空间之中，然后通入惰性气体于该真空空间之中以防止钨丝于高温状态下氧化。白炽灯是一种非常浪费能源的灯具，原因在于白炽灯会把约90％的电能转化成无用的热能，只有少部份(约10％)的电能会贡献于白炽灯所发出的光之上。因此，白炽灯逐渐地被淘汰使用，而用以取代白炽灯的新型灯具即称之为节能灯。
请参阅图1A与图1B，是传统节能灯的第一立体图与第二立体图。如图1A所示，节能灯1’又称为紧凑型荧光灯，其是由一壳体11’、多根灯管12’与一灯头13’所构成，其中，灯管12’呈现U型状，且其内设置有灯丝，灯丝上则涂布有一些电子粉；此外，灯管12’内更充注有水银(即俗称汞)，且灯管12’同时涂布有荧光物质。如此，当灯丝通电加热时，电子粉便释出具有一定速度与能量的电子流，且电子流会打在水银上，使得汞原子受到激发，同时释放出紫外光，而荧光物质受到紫外光的激发后便会发出适用于照明的光。另外，如图1B所示，螺旋状的灯管12’也经常使用于传统节能灯1’之中。
上述的节能灯1’虽然具有节能省电以及360O发光的优点；然，本案的发明人经长期研究后发现，现有的节能灯1’显现出几个使用上的缺陷：
1.节能灯在使用时，会产生些微的电磁波与微波，在长期使用下，这些电磁波与微波可能会对人体造成伤害。
2.节能灯的所包含汞与紫外线等会对人体产生伤害的材料；而现实之中也有许多中国工人因为制造节能灯而汞中毒。
3.演色性较低：白炽灯及卤素灯的演色性为100，表现完美，然而节能灯的演色性大多仅在于80至90之间。
4.基于节能灯的制造材料包含汞、电子粉、灯丝、荧光物质等多种材料，使得其制造成本无法有效压低，连带着造成其售价偏高。
因此，有鉴于传统节能灯具有太多缺点，灯具制造商推出LED灯具以取代传统节能灯具。请参阅图2A与图2B，是LED灯具的第一分解图与第二分解图。如图2A所示，现有的LED灯具2’经常制作成烛台用灯具，其结构上包括：一灯座21’、一绝缘基座22’、一多块电路板23’、多个LED元件24’、以及一灯罩25’；其中，该多块电路板23’的数量为4块，且该4块电路板23’是相互正交。并且，该4块电路板23’是藉由该绝缘基座22’而设置于该灯座21’的一设置部211’之上。再者，该多个LED元件24’是设于该4块电路板23’的表面；并且，该些LED元件24’是受控于该电路板23’上的一驱动控制电路模块26’而发光。另外，如图2B所示，LED灯具2’也经常制作成球泡灯。
上述的LED灯具2’虽然可以解决传统节能的缺点；然，本案的发明人经长期研究后发现，现有的LED灯具2’显现出几个使用上的缺陷：
(1)如图2A所示，由于该LED灯具2’藉由相互正交的4块电路板23’上的该些LED元件24’而发光，因此，该LED灯具2’的顶部将因为没有设置任何LED元件24’而无法发出任何光线；也就是说，该LED灯具2’的顶部将成为明显的光学暗区。另外，如图2B所示，虽然将LED灯具2’制作成球泡灯结构是能够达到超过180o的光罩范围，但仍无法达到270o以上。因此，基于上述理由，该LED灯具2’无法应用作为一全周光LED灯具。
(2)如图2A所示由于该LED灯具2’的结构上使用了多块电路板23’以及一个绝缘基座22’，因此，该些LED元件24’发光所产生的热将会因为该LED灯具2’缺乏有效的散热路径或散热结构而堆积于该些电路板23’之上，进一步地，不断的热堆积最终导致LED元件24’的故障或者烧坏该驱动控制电路模块26’。另外，如图2B所示的球泡灯结构，虽然已经于灯座21’侧边形成散热鳍片结构212’，但由于电路板23’是由导热性差的玻纤板所制成，因此该些LED元件24’发光时所产生的热，仍然难以传递至散热鳍片结构212’以进行散热。
(3)承上述第2点，由于该LED灯具2’的结构设计上显现出了热电合一(光源即发热源)以及热源集中等缺陷，加上该LED灯具2’的散热效果极差，导致该LED灯具2’无法被应用作为一高功率(＞20W)LED灯具。
经由上述，可以得知现有的LED灯具2’于结构组成的设计上仍有所不足；有鉴于此，本案的发明人极力加以研究发明，终于研发完成本发明的一种正全周光LED灯具。
发明内容
本发明的主要目的，在于提供一种全周光LED灯具，其是由一灯座、多根灯管、多个自黏基板、多个第一LED元件、一承载板、多个第二LED元件、以及一透明罩体所构成，具有构造简单、制造成本低、不须使用任何玻纤电路板等优点。此外，于本发明的全周光LED灯具的设计上，是将全周光LED灯具的瓦数平均分担至每一根灯管之上，并且，由于该些第一LED元件是通过自黏基板而直接贴附于灯管内壁，因此，该些第一LED元件所产生的热发光时所产生的热亦可通过灯管而直接散逸至空气中，而不会于灯管内产生热堆积的现象。也就是说，每一根灯管本身是光源也是散热源；再者，由于本发明是采用分离式光源的设计，因此达到分散式散热的功效。。

此外，为了达成本发明的主要目的，本发明又提出一种全周光LED灯具的另一实施例，包括：

多个第二LED元件，设置于该多个自黏基板的该弯折部之上，并与该第二线路层电性连接；其中，该LED驱动模块控制该些第一LED元件以及该些第二LED元件的发光。
再者，为了达成本发明的主要目的，本发明又提出一种全周光LED灯具的再一实施例，包括：

为了能够更清楚地描述本发明所提出的一种全周光LED灯具，以下将配合图式，详尽说明本发明的较佳实施例。
请参阅图3与图4，本发明的一种全周光LED灯具的立体图及其分解图。如图3与图4所示，本发明的全周光LED灯具1包括：一灯座11、多根灯管12、多个自黏基板13、多个第一LED元件14、一承载板16、多个第二LED元件18、以及一透明罩体19；其中，该灯座11至少具有一电性连接件111与一灯管组合件112。如图所示，该电性连接件111为该灯座11的下半部，用以耦接一外部电源。灯管组合件112的内部设置有一LED驱动模块15，且该LED驱动模块15耦接该电性连接端111；并且，灯管组合端112的表面上设置有多个灯管插孔1121。
继续地参阅图3与图4，并请同时参阅图5的单一灯管与单一自黏基板的某一视角立体图以及图6的多根灯管、多个自黏基板、与承载板的立体图。如图所示，该多根灯管12藉由分别插入该多个灯管插孔1121的方式而组装至该灯管组合件112之上，且每一根灯管12至少具有一顶部开口121。另，多个自黏基板13分别设置于该多根灯管12的内壁，且每一个自黏基板13的一基部13a的表面上形成有一第一线路层131以电性连接于该LED驱动模块15；并且，每一个自黏基板13更具有一弯折部13b，其中，该弯折部13b自该顶 部开口121延伸而出，且该弯折部13b与该基部13a之间具有一夹角；并且，弯折部13b的表面上形成有电性连接于该第一线路层131的一第二线路层134。
承上述的说明，该多个第一LED元件14设置于该多个自黏基板13的该基部13a的表面上，并与该些第一线路层131电性连接。并且，多个第二LED元件18，设置于该多个自黏基板13的该弯折部13b之上，并与该第二线路层134电性连接。如图4所示，由于弯折部13b与基部13a构成L形的自黏基板13，如此设计，当该LED驱动模块15控制该些第一LED元件14以及该些第二LED元件18发光时，该些第一LED元件14所发出的光会由LED灯具1的四周围射出，且该些第二LED元件18所发出的光会由LED灯具1的顶部射出，使得LED灯具1所发出的光为一全周光。另外，本发明更于该灯座11内设置耦接于该LED驱动模块15的一个震动感测器(未图示)。如此，当该震动感测器感测到该LED节能灯具1受到一定程度的震动时，该震动感测器即断开该LED驱动模块15与该些第一LED元件14及该些第二LED元件18的电性连接。这样的设计是为了于此全周光LED节能灯具1掉落地的同一时间就切断电源，进而避免使用者捡拾掉落的灯具的时不小心触电受伤。
再者，如图7的多根灯管与承载板的立体图所示，该承载板16以其周缘的多个凹口162分别嵌住该多根灯管12，使得承载板16的设置位置位于该多根灯管12之间，并靠近该多根灯管12的顶部，进而承载该多个自黏基板13的该弯折部13b。此外，本发明更以一透明罩体19套住该些灯管12的该顶部开口121，藉以覆盖保护该承载板16与该些第二LED元件18。
请再同时参阅图8A与图8B，透明罩体的某一视角正视图以及另一视角正视图。如图所示，为了使得承载板16上的该些第二LED元件18所发出的光能够具有最大的发光角度，特别于透明罩体19的顶部上形成有一光学透镜191，且该光学透镜191为一LED散光透镜，例如：凸透镜。并且，该光学透镜191亦可藉由覆盖一光扩散材料于该透明罩体19的顶部表面的外壁或者内壁而完成。
继续地，请参阅图9，灯管的其它实施态样的立体图。于此，必须特别说明的是，虽然图3与图4所绘示的灯管12的数量为4根，但并非以此限制本发明的实施例；实际应用时，灯管12的数量可根据全周光LED灯具1的瓦数进行调整。举例说明，假设该全周光LED灯具1的瓦数为20瓦，则灯管12的数量可设计为4根；另，若该全周光LED灯具1的瓦数为15瓦，则灯管12的数量可设计为如图9所示的3根。也就是说，于本发明的全周光LED灯具1的设计上，是将全周光LED灯具1的瓦数平均分担至每一根灯管12之上，如此，即便全周光LED灯具1长时间不间断地发光，每一根灯管12内的第一LED元件14所产生的热亦不会过高；再者，由于该些第一LED元件14是通过自黏基板13而直接贴附于灯管12内壁，因此，该些第一LED元件14所产生的热发光时所产生的热亦可通过灯管12而直接散逸至空气中，而不会于灯管12内产生热堆积的现象。
于此，再一次简述上述本发明的重要技术特征。本发明采用分离式光源的设计，每一根灯管12即是一组光源；并且，由于该些第一LED元件14是通过导热性非常良好的自黏基板13而直接贴附于灯管12内壁，因此，该些第一LED元件14发光时所产生的热便即时藉由自黏基板13传导至玻璃材质的灯管12，然后由玻璃材质的灯管12即时性地散热；也就是说，每一根灯管12本身是光源也是散热源。再者，由于本发明采用分离式光源的设 计，因此达到分散式散热的功效。
此外，不管是图3所示的灯管12或者图9所示的灯管12，其底部可更形成有一底部开口，使得灯管12成为玻管式灯管(即，双开口灯管)的形式，且，灯管12的底部开口插入该灯管插孔1121。此外，灯管12的内壁或外壁喷涂有一光学扩散涂料，该光学扩散涂料有助于增加灯管12内的第一LED发光元件14所发出的光的发光角度。另外，就灯管12的材质而言，灯管12可以是全透明玻璃灯管或全透明塑胶灯管；并且，为了增加光的散射，灯管12也可以是光扩散玻璃灯管或者光扩散塑胶灯管。
承上述的说明，当灯管12为全透明玻璃灯管之时，可搭配使用一张光扩散防爆保护膜来覆盖全透明玻璃灯管；相反地，若灯管12为光扩散玻璃灯管之时，便搭配使用一张全透明防爆保护膜与以覆盖保护。必须加以补充说明的是，若灯管12为导热塑胶与光扩散塑胶的复合灯管、导热型全透明塑胶灯管、或者导热型光扩散塑胶灯管时，则可省去防爆保护膜的使用。再者，除了前述贴附式防爆保护膜外，防爆保护膜也可以是热缩式套膜，例如光扩散热缩套膜或者透明热缩套膜。进一步地，防爆保护膜也可以通过喷涂的方式而成型于灯管12之上，例如喷涂成型式光扩散保护膜与喷涂成型式透明保护膜。最后，也可以将灯管12浸泡于一胶液之中而使得保护膜成型于灯管12之上，例如含浸成型式光扩散保护膜或含浸成型式透明保护膜。
请继续参阅图10A与图10B灯座11的各种实施态样的立体图。虽然图3与图4所示的灯座11的电性连接件111为一旋转灯头，但不以此限制灯座11的实施态样。如图10A所示，灯座11的电性连接端111可通过两个电性连接端子而插入该外部电源的二电性插槽。并且，如图10B所示，灯座11的外型不限于圆筒，其也可以是立方体的设计。
除了上述说明所介绍的全周光LED灯具1的第一实施例以外，本发明更提供该全周光LED灯具1的第二实施例。请参与图11，该全周光LED灯具的第二实施例的分解图。如图11所示，该全周光LED灯具1的第二实施例包括：一灯座11、多根灯管12、多个自黏基板13、多个第一LED元件14、一支撑件17、一承载板16、多个第二LED元件18、以及一透明罩体19；其中，第二实施例的该多根灯管12、该多个自黏基板13、该多个第一LED元件14、该承载板16、该多个第二LED元件18、以及该透明罩体19的设计皆相同于前述第一实施例的灯管12、自黏基板13、第一LED元件14、承载板16、第二LED元件18、与透明罩体19的设计；基于这个理由，于此便不再重复说明之。于第二实施例中，该灯管组合件112的表面上更设置有一插孔1122，使得一支撑件17可以其一端嵌入该插孔1122，进而设置于该灯管组合件112之上；如此，便可利用该支撑件17的另一端连接支撑该承载板16。
除了上述说明所介绍的全周光LED灯具1的第一实施例与第二实施例以外，本发明更提供该全周光LED灯具1的第三实施例。请参与图12与图13，该全周光LED灯具的第三实施例的立体图与分解图。如图12与图13所示，该全周光LED灯具1的第三实施例包括：一灯座11、多根灯管12、多个自黏基板13、多个第一LED元件14、以及多个第二LED元件18；其中，其中，该灯座11至少具有一电性连接件111与一灯管组合件112。如图所示，该电性连接件111为该灯座11的下半部，用以耦接一外部电源。灯管组合件112的内部设置有一LED驱动模块15，且该LED驱动模块15耦接该电性连接端111；并且，灯管组合端112的表面上设置有多个灯管插孔1121以供该多根灯管12分别插入其中。于第三 实施例中，特别地，每一根灯管12具有一基管部123与一顶部弯管部122。
继续地参阅图12与图13，并请同时参阅图14，单一根灯管与单一自黏基板的立体图。如图所示，该多个自黏基板13分别设置于该多根灯管12的内壁，且每一个自黏基板13具有一基部13a与一弯折部13b；其中，基部13a置于该基管部123之中，且其表面形成有一第一线路层131以电性连接于该LED驱动模块15。并且，与该基部13a之间具有一夹角的弯折部13b置于该顶部弯管部122之中，且其表面形成有一第二线路层134以电性连接于该LED驱动模块15。
此外，该多个第一LED元件14是设置于该多个自黏基板13的该基部13a的表面上，并与该些第一线路层131电性连接，并且，该多个第二LED元件18是设置于该多个自黏基板13的该弯折部13b之上，并与该第二线路层134电性连接。如图13所示，由于弯折部13b与基部13a构成折弯型自黏基板13，如此设计，当该LED驱动模块15控制该些第一LED元件14以及该些第二LED元件18发光时，该些第一LED元件14所发出的光会由LED灯具1的四周围射出，且该些第二LED元件18所发出的光会由LED灯具1的顶部射出，使得LED灯具1所发出的光为一全周光。
继续地参阅图15，多根灯管与多个自黏基板的立体图。如图14与图15所示，灯管12的一端可形成有一顶部开口121，使得自黏基板13的弯折部13b露出于灯管12的基管部123之外；并且，可于灯管12的另一端更形成有一底部开口，且该底部开口插入该灯管插孔。此外，更可以一透明端盖12a套设于该顶部开口121以作为灯管12的顶部弯管部122。
如此，上述已完整且清楚地说明本发明的全周光LED灯具的详细构件与结构特征，并且，经由上述，可以得知本发明具有下列的优点：
(1)相较于现有的LED节能灯，本发明的全周光LED灯具由一灯座11、多根灯管12、多个自黏基板13、多个第一LED元件14、一承载板16、多个第二LED元件18、以及一透明罩体19所构成，具有构造简单、制造成本低、不须使用任何玻纤电路板等优点。
(2)此外，于本发明的全周光LED灯具1的设计上，采用分离式光源的设计，将全周光LED灯具1的瓦数平均分担至每一根灯管12之上；再者，由于该些第一LED元件14是通过自黏基板13而直接贴附于灯管12内壁，因此，该些第一LED元件14所产生的热发光时所产生的热亦可通过灯管12而直接散逸至空气中，而不会于灯管12内产生热堆积的现象。也就是说，每一根灯管12本身是光源也是散热源。再者，由于本发明采用分离式光源的设计，因此达到分散式散热的功效。
(3)再者，本发明是将具有多个第二LED元件18的一承载板16嵌设于该多根灯管12之间；如此，当该承载板16上的该些第二LED元件18以及该多根灯管12内的该些第一LED元件14同时发光时，不会于本发明的全周光LED灯具1的任何一处产生光学暗区。因此本发明的全周光LED灯具1可以取代现有的烛台用LED灯具以及全周光球泡型LED灯具；当然，也可以取代传统的U型灯管节能灯以及螺旋灯管节能灯。
除此之外，本发明的全周光LED灯具1更包括一第四实施例。请参阅图16，本发明的全周光LED灯具的第四实施例的分解图。如图16所示，全周光LED灯具的第四实施例包括：一灯座11、多根灯管12、多个自黏基板13、多个第一LED元件14、至少一第二LED元件18；其中，该灯座11与该多根灯管12的实施态样相同于前述第一实施例。不同的是，第四实施例的自黏基板13包括一基部13a与一翘起部13c。
继续地参阅图16，并请同时参阅图17，灯管与基板的立体图。如图16与图17所示，基部13a的表面上形成有一第一线路层131以电性连接于该LED驱动模块15，且翘起部13c的表面形成有电性连接于该第一线路层131的一第二线路层134以电性连接于该LED驱动模块15。并且，该多个第一LED元件14设置于该多个自黏基板13的该基部13a的表面上，并与该些第一线路层131电性连接。该第二LED元件18则设置于该多个自黏基板13的该翘起部13c之上，并与该第二线路层134电性连接。特别地，于第四实施例之中，翘起部13c是呈现倒V状，且其底部由一支撑件13d所支撑。如图所示，该支撑件13d为一三角形块状物，但不以此为限。在实际的应用中，支撑件13d也可以由一铝板金件弯折成倒V状的支撑件13d，或导热材V状的支撑件。
如此设计，使得第二LED元件18的发光面朝向灯管12上方，并使得该些第一LED元件14的发光面朝向灯管12的侧面，所以当该LED驱动模块15控制该些第一LED元件14以及该些第二LED元件18发光时，该些第一LED元件14所发出的光会由LED灯具1的四周围射出，且该些第二LED元件18所发出的光会由LED灯具1的顶部射出，使得LED灯具1所发出的光为一全周光。
如图18所绘示的灯管立体图所示，第四实施例所使用的灯管12，其灯管12一端可形成有一顶部开口121，使得自黏基板13的翘起部13c露出于灯管12之外；并且，更可以一透明端盖12a套设于该顶部开口121。
当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
