Description

具散热结构的灯具基座及其灯具、照明装置 技术领域
发明涉及灯具的技术领域，特别地，涉及一种可大幅增进LED散热效益之的具散热结构的灯具基座及其灯具、照明装置。
背景技术
在现有之照明装置中，通常都会设置至少一发光组件，藉以对外界环境投射出至少一照明光束来提供照明效果。在实务运用层面上，由于发光二极管(Light Emitting Diode；LED)具备高功率、高照度、低耗电与使用寿命长之效果，因此近年来逐渐地被大量用来制作上述之照明组件。
　　　由于LED在对外界环境投射出照明光束时，会散发出热能。若LED所散发出的热能无法有效地被逸散，将不仅会影响到LED的正常运作，降低LED使用寿命且造成光衰，甚至使LED坏损。因此，在大多数照明装置中，多半都会设置一散热模块，并藉由散热模块之结构或材料特性方面的改良而提升散热效果。然而高亮度和低耗能的照明装置会导致电路密度和发热源增加，因此仅采用传统片状之散热鳍片的具散热结构的灯具基座是不够的，从而在热传导与热对流方面都应有更精进的需求。
　　　综观之前所述，发明的发明人思索并设计了一种具散热结构的灯具基座及其灯具、照明装置，经多年苦心研究，以针对现有技术的缺失加以改善，进而增进产业上的实施利用。
 技术问题
基于上述现有技术的问题，发明目的在于提供一种具散热结构的灯具基座及其灯具、照明装置，以解决习知技艺的LED灯具的散热问题。

 本发明的实施方式
为便于了解发明的技术特征、内容与优点及其所能达成的功效，兹将发明配合附图，并以实施例的表达形式详细说明如下，而其中所使用的附图，其主旨仅为示意及辅助说明书，并不是发明实施后的真实比例与精准配置，因此，不能将后续附图的比例与配置关系解读、限制发明在实际实施上的权利范围，在此提前说明。
　　　以下将参照相关附图，说明根据发明具散热结构的灯具基座及其灯具、照明装置的实施例，为便于理解，下述实施例中相同组件以相同的符号标示来说明。
　　　请参阅图1、2及3，其分别为本发明灯具的第一实施例的爆炸示意图、组合示意图及灯具基座的俯视角示意图。灯具1包含了具散热结构的灯具基座11、风扇12及发光模块13。其中灯具基座11设置于风扇12及发光模块13之间。即，风扇12固定于灯具基座11的一端，而发光模块13则固定于灯具基座11的另一端，以利用灯具基座11吸取发光模块13及其具有的至少一个发光二极管（未绘示于图中）的热量，且利用风扇12带动环境气体的流动，从而进行对发光模块13的散热。
　　　灯具基座11更包含了多个散热件111、鳍片部112及散热通道113。散热件111可为铝或铜等具良好散热性能的材质，经由挤出成型或铣削加工等方式制成各散热件111形状相互对应的外形，以利用形状相互对应的将散热件111组合成为灯具基座11的本体。其中散热件111的数量可为二个以上，例如二个、三个或四个，于本实施例中是以四个作为示范态样，但并不以此为限。鳍片部112设置于散热件111未与相邻的散热件111连接的外壁面上，且鳍片部112是由多个鳍片1120所组成。散热通道部113设置于散热件111与相邻的散热件111连接的连接壁面1110上。其中，散热通道部113由散热件111的一端向散热件111的另一端延伸，且于邻近散热件111的另一端处转折延伸向散热件111的外壁面，而连通散热件111的一端与邻近于散热件111的另一端的散热件111的外壁面。其中，散热通道部113的通道尺寸由散热件111的一端往散热通道部113的转折部1130逐渐的缩小。
　　　详细来说，散热件111可为一个四分之一的圆形形状结构，当四个散热件111进行组合时则成一个圆柱形结构(如图3所示)。鳍片部112则设置于四分之一的圆形形状结构的圆周上（即，外壁面），而散热通道部113则设置于连接于四分之一的圆形形状结构的直线壁面上（即连接壁面1110）。散热件111更具有一连接部1111，其位于连接壁面1110与外壁面之间，即连接壁面1110的两侧边上分别具有一连接部1111。接著，连接壁面1110的一侧的连接部1111上设置有多个通孔11110，而连接壁面1110的另一侧的连接部1111对应通孔11110设有多个栓接孔11111。当四个散热件111进行组合而成为灯具基座11时，可藉由多个栓接组件穿过通孔11110而锁附于栓接孔11111，以使四个散热件111可稳定地相互组合。在实际运用中，为了利于进行锁附固定，其中灯具基座11的中心至连接部1111的边缘的距离可大于灯具基座11的中心至鳍片部112的鳍片1120的边缘。换句话说，连接部1111是凸出于鳍片1120的。
　　　其中鳍片部112对应风扇12的风扇固定孔120于其中一或二的鳍片1120的末端设有C字型形状的固定部1121。同样的，鳍片部112对应发光模块13的发光模块固定孔130于其中一或二鳍片的末端设有固定部1121。较佳的实际运用中，可将固定部1121、风扇固定孔120及发光模块固定孔130三者设置为同样的相对位置，藉此，仅需一组固定部1121即可同时地供给风扇12及发光模块13进行固定。即，组装时可利用螺丝等组件穿过风扇固定孔120及穿过发光模块固定孔130而锁附于固定部1121，以将风扇12及发光模块13分别固定于灯具基座11的两端。
　　　另一方面，散热通道部113可为由连接壁面1110向内凹陷的半圆弧形形状。也就是说，当其中二个或四个散热件111进行结合时，半圆弧形形状的散热通道部113则可形成一个完整个圆形形状结构，即为形成一个完整的散热通道。另外，于连接壁面1110上的散热通道部113的数量可为两个，即散热通道部113分别设置在以90?角相连接而成为L字型形状的连接壁面1110的各侧壁面上。亦即，当四个散热件111进行结合时可形成四个完整的散热通道。再者，散热通道部113更包含流体接收部1131及流体排出部1132。流体接收部1131的一端位于散热件111的一端，而流体接收部1131的另一端连接转折部1130。流体排出部1132的一端位于散热件111的外壁面，流体排出部1132的另一端连接于转折部1130。简单的说，转折部1130连接于流体接收部1131及流体排出部1132之间。其中流体接收部1131可由散热件111的一端的端面上，且邻近中心处向散热件111的另一端略微向外偏斜的伸延，而连接至转折部1130。而连接于转折部1130的另一端的流体排出部1132则是以斜向散热件111的另一端的方向延伸，从而连接至散热件111的外壁面上。藉此，可增加热量与流动空气的接触面积。值得注意的是，散热通道部113的通道尺寸由散热件111的一端往散热通道部113的转折部1130逐渐的缩小，即于流体接收部1131的部分通道尺寸是逐渐缩小的，而于转折部1130及流体排出部1132的通道尺寸是一致的。当然地，转折部1130及流体排出部1132的通道尺寸亦可进一步地设置为逐渐缩小的，故应不可以此为限。
　　　请进一步参阅图4，其是本发明灯具的第一实施例的气体流动示意图，于图中以由其中两个散热件进行组合后的半圆形结构作为表示及说明。如图所示，风扇12设置于灯具基座11远离转折部1130的一端。即，流体接收部1131处。风扇12可带环境的气体进行流动，而将环境的气体吸入流体接收部1131中。由于，气体不断的被吸入流体接收部1131中，因而后续进入的气体将推抵于流体接收部1131中的气体往转折部1130流动，且由于通道尺寸的由大变化为小，也增加了气体的流动速度，从而迅速的由流体排出部1132排出。亦即，于散热通道方面主要是利用转折部1130及流体排出部1132来进行散热的动作，且转折部1130的位置亦为灯具基座11吸收发光模块13的热量后，热量的主要的集中区域。顺带一提的是，连接壁面1110上的四个流体接收部1131可相融合于一起，以利于接收风扇12所带入的流体。
　　　值得一提的是，灯具基座11的长度可为60mm至160mm之间，优选地，灯具基座11的长度可为60mm、80mm、100mm及160mm。其中长度尺寸为80mm、100mm及160mm的灯具基座11的灯具1可适用于室外或室内的灯具，而长度尺寸为60mm的灯具基座11的灯具1可适用于室内的灯具。其中室外的灯具例如路灯、隧道灯等室外灯具，而室内的灯具例如嵌灯、聚光灯、装饰灯或挂灯等室内灯具。而于实际运用中，可先制作出长度为160mm的灯具基座11，再依不同的需求以对长度为160mm的灯具基座11的具有流体接收部1131的一端进行切除的动作，以其可符合需求的长度。换句话说，当需求的长度愈短，流体接收部1131的长度则随之愈短。当然地，亦可直接以调整散热通道部113的整体比例的方式，以使其可符合需求的长度。
　　　请参阅图5及6，其分别为本发明灯具的第二实施例的爆炸示意图及组合示意图。于本实施例中，相同的组件的连结关系与动作均与前一实施例类似，其类之处于此便不再赘述。本实施例与前一实施例的不同处在于，本实施例中是以二个散热件111作为示范态样。
　　　详细来说，本实施例中的灯具1的灯具基座11主要是由二个散热件111所组合而成的。当由灯具基座11的俯视或仰视观之时，各散热件111呈现半圆形形状的结构，从而同样可组合成圆柱形形状的灯具基座11（如图6所示）。此时，若散热通道部113的数量为两个时，则散热通道部113则设置于半圆形形状结构的直线壁面上（即，以180?角相连接而成的连接壁面1110），且其为镜射的方式配置于连接壁面1110；若散热通道部113的数量为一个时，则散热通道部113选择地设置在邻近其中一侧的连接部1111的连接壁面1110上即可。于本实施例中，散热通道部113的数量以两个作为示范态样。换句话说，当二个散热件111组合形成灯具基座11时，散热通道的数量则为二个。此时，风扇12带入的气体则可由二方向上的流体排出部1132排出。
　　　请参阅图7，其为本发明照明装置的实施例的示意图。于本实施例中，相同的组件的连结关系与动作均与前二实施例类似，其类之处于此便不再赘述。本实施例不同处在于，本实施例中是将多个灯具1阵列放置于一起而形成照明装置2作为示范态样。照明装置2包含了多个第一实施例或第二实施例中所述的灯具1及固定架21。固定架21具有对应容置多个灯具1的容置口210，以使灯具1可阵列的排列于容置口21中。其中，多个灯具1可以圆形、矩形等方式阵列排列，于本实施例中是以矩形作为示范态样，但不以此为限。另外，灯具1固定于固定架21的容置口21中的方式可利用锁附、卡接等方式，例如，于连接部1111的侧壁上增设一锁附孔（未绘示于图中），以利用螺丝等组件穿过固定架21而锁附于锁附孔，以将灯具1。故灯具1固定于固定架21的技术，是为所属领域技术人员所熟知，于此便不再加以赘述。
　　　综上所述，本发明的具散热结构的灯具基座及其灯具、照明装置在利用鳍片散热外，更藉由散热通道及其预定的配置方式，以增加散热气体的流动、接触位置及面积，从而可大幅的增加散热效果。
　　　以上所述仅为示例，而非为限制发明。任何未脱离发明的精神与范畴，而对其进行等效修改或变更，均应包含在本申请的权利要求范围中。
