Description

可加大照射范围的光源模块及灯具结构
技术领域
[0001] 本实用新型涉及一种可加大照射范围的光源模块及灯具结构,特别是涉及一种可将光线导引至后方的可加大照射范围的光源模块及灯具结构。
背景技术
[0002] 一般的光源模块,根据发光原理的不同,可分为许多形式。以使用发光二极管作为其光源的光源模块,因为具有良好的光转换效率、波长固定以及光亮、光质可调整等特点而成为当今最被广为使用的光源模块之一。除此之外,发光二极管更具有体积小、低发热量且使用寿命较长的优点。
[0003] 然而,此类光源模块即使拥有上述许多优点,却仍有其先天之缺陷。不论光源本身的发光原理是何种方式,皆仍受限于其照射范围的方向性,一般来说,发光二极管光源的照射范围约为120度,故其向前方直射的正向光最强,而侧边及后方的光源则相对较弱甚至·无法照明,因此造成所谓的无效区域(或称暗区)。为了加强该些无效区域的照明,经常就需要加设更多照明灯具以加强其照明效果,这样却徒增了能源的浪费及消耗。
实用新型内容
[0004] 本实用新型提供了一种可加大照射范围的光源模块及灯具结构,可将光源导引至其后方,减少无效区域,进而加大照射范围。本实用新型解决其技术问题的所采用的技术方案是:
[0005] 一种可加大照射范围的光源模块,它包括:
[0006] 一呈弧形的导光柱,该导光柱的表面形成有数个能起散射、折射、发射作用的微结构;以及
[0007] 二发光二极管光源,与该导光柱的两端相对应。
[0008] 一较佳实施例之中:该导光柱的两端分别设有一容置空间,该二发光二极管光源分别容置于该二容置空间中。
[0009] 一较佳实施例之中:该导光柱表面所形成的该微结构呈角锥状或圆锥状或圆球状。
[0010] —较佳实施例之中:该导光柱表面所形成的该微结构散布在该导光柱的表面上。
[0011] 一较佳实施例之中:该二发光二极管光源连接于一导热部上。
[0012] 一种灯具结构,它包括:
[0013] 至少一呈弧形的导光柱,该导光柱的表面形成有数个能起散射、折射、发射作用的微结构;
[0014] 至少二发光二极管光源,与该导光柱的两端相对应;
[0015] 一散热部,其设有数个散热鳍片,该散热部一端设有一电源座,该散热部另一端设有一接触面;以及
[0016] 一导热部,其连接于该接触面之上,该导热部上装设有所述导光柱。[0017] 一较佳实施例之中:所述导光柱的两端分别设有一容置空间,所述发光二极管光源分别容置于所述容置空间中。
[0018] 一较佳实施例之中:所述这些散热鳍片呈相互间隔排列。
[0019] 一较佳实施例之中:该导热部为一电路板。
[0020] 本技术方案与背景技术相比,它具有如下优点:
[0021] I.光线行经该导光柱并且受该些微结构的影响,产生散射、折射、反射等,将光线逐步引导至该光源模块的后方,从而加大其照射范围,减少无效区,使该光源模块及该灯具结构具有可加大照射范围的优点。
[0022] 2.该光源模块及该灯具结构不必另外增设更多照明灯具来加强其照明效果,具有
节省能源的优点。
[0023] 3.该导光柱设计小巧,可一次安装数个于该导热部之上,以加大该光源模块的亮度。

具体实施方式
[0036] 请参阅图I至图3,本实用新型的一种可加大照射范围的光源模块,包括有:一呈弧状的导光柱I、数个形成于其表面的微结构11、设置于该导光柱I两端的二容置空间12,以及与该导光柱I的两端相对应的二发光二极管光源13。
[0037] 该微结构11为一系列经过计算及实验后所设计而成的特殊构造,其形状可呈角锥状、或圆锥状、或者圆球状(分别如图5A、5B、5C所示),且散布于该导光柱I的表面上。该二发光二极管光源13分别容置于该导光柱I的二容置空间12中,并且电性连接于一导热部3。该二发光二极管光源13是由该导热部3驱动电力而产生照明光线,其光线行经该导光柱I并且受该些微结构11之影响,而产生各种如预期之效果诸如散射、折射、及反射等(如图4所示),其目的在于将光线逐步引导至该光源模块的后方,以减少无效区(暗区),并加大其照射范围。
[0038] 本实用新型另外提供一种灯具结构,除包括上述光源模块外,进一步包括一散热部2以及一导热部3。该散热部2的侧面设有数片散热鳍片21,该散热部2 —端设有一电源座22,另一端设有一接触面23。
[0039] 该些散热鳍片21相互间隔排列于该散热部2的侧面,其功用为增大与空气间之接触面积以加速对流,藉此加速散热。该电源座22系为金属材质,可连接于外接之电源并且导电。该接触面23上设有一孔洞(图略),用以做电源之连接。
[0040] 该导热部3为一电路板,其一侧设有数个发光二极管光源13,另一侧则设有二条电源线(图略),该二条电源线系穿透过该孔洞并且电性连接于该电源座22,当形成通路时即可驱动该些发光二极管光源13以达到照明之目的。该导热部3系连接于该接触面23之上,藉此将该些发光二极管光源13所产生之热能,经由热传导之方式,从该接触面23将热导引至该些散热鳍片21以进行对流而散热。本实施例中同时具有三组光源模块,该三组光源模块的排列方式呈等角度间隔设置,惟上述光源模块之数量及排列方式实际上并无特定限制。 [0041] 本实用新型之可加大照射范围的光源模块,藉由导光柱以及微结构之设计,可有效的引导光线以减少无效区,进而达到其加大照射范围之目的,并且,该导光柱具有设计小巧之特色,故可一次安装数个于该导热部之上,以加大该光源模块之亮度。
[0042] 以上所述,仅为本实用新型较佳实施例而已,故不能依此限定本实用新型实施的范围,即依本实用新型专利范围及说明书内容所作的等效变化与修饰,皆应仍属本实用新型涵盖的范围内。
