Description

固态照明装置
技术领域
本发明涉及一种固态照明装置，特别是一种发光二极管照明装置。
背景技术
目前，发光二极管(Light Emitting Diode，LED)因具光质佳(也即LED光源射出的光谱)及发光效率高等特性而逐渐取代冷阴极荧光灯(Cold Cathode Fluorescent Lamp，CCFL)作为固态照明装置的发光元件，具体可参阅Michael S.Shur等人在文献Proceedingsof the IEEE，Vol.93，No.10(2005年10月)中发表的“Solid-State Lighting：Toward Superior Illumination”一文。
对于现有采用发光二极管作为发光元件的照明装置，其通常具有近似圆对称的光场，这些光场的中心光强度较强，由中心向四周扩散的区域光强度逐渐减弱，该光场的光强度分布不均匀，无法获得较佳的光利用效率和光均匀度。如图1所示，一种发光二极管照明装置10包括一发光模组11及一扩散板16，该发光模组11包括一电路板14及设置于该电路板14上的若干发光二极管12。由于该发光二极管12发出的光线直接向上照射自扩散板16的下侧进入，容易使得该扩散板16与发光二极管12相对的部分亮度较高，而远离该发光二极管12的部分亮度则相对较暗，从而造成该发光二极管照明装置10的出光均匀度较低。
发明内容
有鉴于此，有必要提供一种出光均匀度较高的固态照明装置。
一种固态照明装置，包括一发光模组，该发光模组包括一电路板及设于该电路板上的若干发光单元，还包括一散热器、至少一支撑体和至少一光学微结构，该散热器包括一基座，该至少一支撑体及该至少一光学微结构均设于该基座的一承载面上，该至少一支撑体的侧面与该承载面的法向量之间具有一夹角，该发光模组设置在该至少一支撑体的侧面上，且与该至少一光学微结构相邻。
与现有技术相比，本发明固态照明装置包括具有基座的散热器及设置于该基座上的承载面上的支撑体，且该支撑体的侧面与该基座的承载面的法向量之间呈夹角，通过将发光单元设于该侧面上，使该发光单元的发光角度可随着该侧面的倾斜角度旋转一定角度，该发光单元所发出的光线中部分光线向该承载面所在方向照射，并通过光学微结构的散射沿不同角度向远离该基座的承载面的方向照射，从而实现该固态照明装置出光均匀度较高的目的。

具体实施方式
下面参照附图，结合具体实施例对本发明作进一步的描述。
如图2所示为本发明固态照明装置的第一实施例，包括一散热器20、设于该散热器20上的一发光模组30及布设于该散热器20表面上的若干光学微结构40。
该散热器20采用高导热率的金属材料制成，如铜、铝、铜合金或铝合金等材料制成，其包括一平板形的基座21，从该基座21的下表面向下延伸的若干散热鳍片23及从基座21的上表面向上凸设的若干支撑体25。该基座21的上表面为一承载面210，该若干支撑体25间隔排列于该承载面210上，每一支撑体25呈长条状，并沿该散热器20的基座21纵向延伸。每一支撑体25平行，每相邻的两支撑体25之间暴露出供所述网点41布设的部分承载面210。该支撑体25通过铝挤的方式与散热器20的基座21一体成型，包括与承载面210相互平行的顶面，以及位于该顶面与该承载面210之间且分别与该承载面210倾斜的左、右两个侧面250。请同时参考图3，本实施例中，每一支撑体25的任一侧面250与承载面210的法向量F之间形成的夹角θ为5度，该支撑体25的横截面的形状为梯形。不同的实施方式中，该支撑体25的左、右两个侧面250与承载面210的法向量F之间夹角的大小可以不同；且支撑体25的形状也可以适当变化，但须使得变化后的支撑体25具有至少一相对该承载面210倾斜的侧面250；该支撑体25可以通过蚀刻、冲压等方式与散热器20一体成型，或者分别单独成型后使用银胶或者焊锡加热后等方式与散热器20相互粘结。
该发光模组30包括若干电路板34及设于该电路板34上的若干发光单元32。本实施例中，该发光单元32为发光二极管，该若干发光单元32分别对应地装设于该电路板34上并与电路板34电性连接。每一电路板34紧密贴设在上述支撑体25的一侧面250上，电路板34与支撑体25之间电性绝缘。其中，该电路板34可以为绕性电路板(Flexiable PCB)或者金属芯基板(Metal Core PCB)。
所述光学微结构40凸设于该基座21的承载面210上，该光学微结构40用以散射发光单元32所发出的光线中向该承载面210照射的光线，使得该部分的光线可改变照射方向沿不同的角度向上照射而达到使发光单元32的出射光均匀分布的目的。本实施例中，所述光学微结构40为紧密排布于相邻两支撑体25之间的承载面210上的圆点状的网点41，该网点41所用材料包括陶瓷，荧光粉，金属或者白色油墨等。该网点41是利用印刷或喷墨等方式形成于该承载面210上。该网点41于承载面210上分布的宽度及紧密度均可根据该发光单元32的发光角度及该支撑体25的侧面250的倾斜角度而调整，至少使得发光单元32所发出的光线中最外侧的光线可照射到最邻近支撑体25的网点41上，防止部分向下的光线直射到承载面210上而损耗。该网点41的形状也可以为其它不规则形状，其具体形状可以在不同的实施过程中根据不同需求来确定。
由于支撑体25的左、右两侧面250均倾斜于承载面210，因此贴设于该侧面250上的发光模组30亦倾斜于承载面210，使该法光模组30中发光单元32的发光角度可随着该侧面250的倾斜角度旋转一定角度，发光单元32所发出的光线中的部分光线向承载面210照射。如图3所示，该侧面250与承载面210的法向量F之间的形成的夹角θ为5度，假设该发光单元32的发光角度θ1为120度，则该发光角度θ1内照射方向低于水平参考线I部分的光线，即角度θ2内的光线均属于射向承载面210的光线，通过计算可知该角度θ2的大小为55度。该向下光线照射在承载面210上，通过该承载面210上网点41的散射后而沿不同的角度向上照射，从而达到照射均匀的目的。当支撑体25的侧面250与承载面210的法向量F之间的夹角θ逐渐增大时，角度θ2的大小将随之变小，即发光单元32所发出的光线中向下照射的光线随之减少。具体实施时，可根据不同发光单元32的发光角度θ1，确定该形成于支撑体25的侧面250与承载面210的法向量F之间的夹角θ的大小，以确保至少有一部分光线向下照射，同时配合该承载面210上网点41分布的范围及密集情况，使尽可能多的光线在网点41的散射作用下向上照射。该种配置方式一方面可以避免发光单元32发出的所有光线均直接向上照射而影响均匀度，另一方面也可以避免发光单元32所发出的光线中部分光线向下照射时，因不能被网点41散射而减弱向上照射的光线的强度。通常，该支撑体25的侧面250与承载面210的法向量之间的夹角θ的大小在5度至85度之间，以保证该角度θ2范围内的向下光线仅占发光单元32发出的所有光线中的少部分，且通过将该部分光线散射后使其可朝不同方向向上照射，从而达到使发光单元32的出射光相对均匀且同时具有较强的强度的目的。该支撑体25不仅可提供供发光单元32设置的倾斜侧面250，而且可将发光单元32产生的热量迅速传导至下方具有较大散热面积的散热器20的基座21及散热鳍片23迅速散发，从而提高了发光模组30的热稳定性，保证了发光单元32具有较高的出光效率。
图4及图5所示为本发明发光二极管照明装置的第二实施例，其与上述第一实施例的区别在于：该光学微结构40为设置于每相邻两支撑体25之间的承载面210上的单片光学凸起物41a。单片光学凸起物41a由散射物质，如掺有陶瓷粉末或荧光粉的硅胶、白色塑胶，或者金属等材料制成。每一单片光学凸起物41a呈长条状，且分别对应地设置于一相邻两支撑体25之间的承载面210上，该每一单片光学凸起物41a与支撑体25平行设置，并沿该散热器20的基座21的纵向延伸。每一单片光学凸起物41a具有单一、连续的外表面，其横截面的形状为半圆形，在不同实施方式中也可以为抛物线形、梯形或者三角形等，该单片光学凸起物41a的高度h不高于发光单元32相对于承载面210的高度H，其作用也在于散射发光单元32所发出的光线中向承载面210所在方向照射光线，使其可沿不同角度向上照射而达到出光均匀度较高的目的。该单片光学凸起物41a可采用射出或者冲压方式等制造成型后与散热器20相互粘结成一体，可以理解的，当该单片光学凸起物41a采用与散热器20相同材料的金属制成时，还可以通过铝挤的方式与散热器20一体成型。该位于任意相邻两支撑体25之间的单片光学凸起物41a分别为一整体，因而制造简单、成型方便，且其连续的外表面可最大限度地散射发光二极管所发出的光线。
另外，本领域技术人员还可于本发明精神内做其它变化，如变更支撑体25的形状、数量及排布方式，光学微结构40的形状、数量及排布方式，发光单元32的结构等用于本发明的设计，只要其不偏离本发明的技术效果均可。这些依据本发明精神所做的变化，都应包含在本发明所要求保护的范围之内。
