Description

配光组件及照明灯具 技术领域
本申请涉及灯具技术领域，尤其涉及一种配光组件及照明灯具。
背景技术
目前，用于教室的照明灯具普遍为朗伯型配光的灯具，而这种配光方式的灯具在照明时，使得灯具正下方的照度很高、而距离灯具较远一点的地方的照度则会很低，即灯具的单灯照度均匀性差，所以为了使整个教室空间的照度均匀性能够达到0.8以上，所以教室空间需要采用多灯布置的方式进行照明，并且每个灯具所照明的边缘区域与周边灯具照明的边缘区域要有很大的照明区域重叠，这样才能达到整个教室照度均匀性的要求。
因此，现有的灯具不仅单灯照射时的照度均匀性差；而且，在多灯布置照明时，还增加了教室空间内的灯具布置密度以及光的重叠区域面积，进而增加了照明成本以及降低了光的利用率。
发明内容

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中 的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
以下结合附图，详细说明本申请各个实施例公开的技术方案。
请参考图1-图7所示，本申请实施例公开了一种配光组件210，所公开的配光组件210包括光扩散元件211、第一光反射元件213和第二光反射元件212；第一光反射元件213和第二光反射元件212分别设置于光扩散元件211相对的两侧，且第一光反射元件213、光扩散元件211和第二光反射元件212之间形成扩口结构的配光室；配光室与光扩散元件211相对的一侧为扩口端214。
同时，光扩散元件211向扩口端214的一侧凹陷形成凹槽结构的光源腔2110，且光源腔2110包括面向第一光反射元件213的反射面的第一扩散部2111、面向扩口端214的第二扩散部2112和面向第二光反射元件212的反射面的第三扩散部2113，即光源腔2110可以将光线扩散至第一光反射元件213的反射面的部分为第一扩散部2111、可以将光线扩散至扩口端214的部分为第二扩散部2112、可以将光线扩散至第二光反射元件212的反射面的部分为第三扩散部2113。
基于上述结构的配光组件210，如图4所示，光扩散元件211形成了具有第一扩散部2111、第二扩散部2112和第三扩散部2113的光源腔2110，并且第一扩散部2111面向第一光反射元件213的反射面，第二扩散部2112面向扩口端214，第三扩散部2113面向第二光反射元件212的反射面；从而使得经第二扩散部2112的出射光大部分可以直接通过扩口端214射出、经第一扩散部2111的出射光可以通过第一光反射元件213的反射面的发射控制后从扩口端214射出、经第三扩散部2113的出射光可以通过第二光反射元件212的反射面的反射控制后从扩口端214射出，进而达到如图5中所示的蝙蝠翼状的配光效果，提高了照射区域内的照度均匀性，并避免了多灯布置时光存在的大面积区域重叠。其中，如图5中所示的蝙蝠翼状的曲线为经过配光组 件210配光后、在C0°剖面上(即经过光源中心轴线、并与光扩散元件211垂直的横截面，如图4所示的截面)的配光效果示意图，水滴状的曲线为光扩散元件211另外两个方向上未经过配光组件210配光、在C90°剖面上(即经过光源中心轴线、并与C0°垂直的剖面)的配光效果示意图。
因此，相较于现有的灯具，本申请所公开的配光组件210可以提高照明灯具在单灯照射时的照度均匀性；并且，在灯具多灯布置时可以减少灯具的布置数量，进而降低照明成本和提高光的利用率。
其中，本申请实施例公开的光扩散元件211可以选用扩散板、扩散片或扩散膜等现有的光扩散元件，从而使得光扩散元件211形成的第一扩散部2111、第二扩散部2112和第三扩散部2113可以对光线进行干涉等、改变光源腔2110内光源的原有配光曲线，并使得光源的光束主要分成上述相应的三部从光扩散元件211射出；同时，第一光反射元件213和第二光反射元件212均可以选用镜面板或镜面铝反射器等现有的镜面反射器，从而可以分别对第一扩散部2111和第二扩散部2112射出的光线进行反射、进而改变出射光线的角度、控制出光方向，达到蝙蝠翼配光曲线；本申请不限制光扩散元件211、第一光反射元件213以及第二光反射元件212选用的具体种类。
为了使得配光组件210形成对称分布的蝙蝠翼配光，第一光反射元件213的反射面和第二光反射元件212的反射面关于光源腔2110的中心轴线呈对称结构，即第一光反射元件213和第二光反射元件212对称设置于光扩散元件211的两侧；通常情况下，光源可以位于光源腔2110的中心轴线上，从而对称设置的第一光反射元件213的反射面和第二光反射元件212的反射面可以更好地保证光照的对称均匀性分布，方便于多灯布置时灯具的排布设置、降低照明布置的难度。
当然，第一光反射元件213的反射面和第二光反射元件212的反射面之间的设置方向也可以为不对称结构，进而使得光分布形成不对称的蝙蝠翼状的配光。例如，第一光反射元件213的反射面和光源腔2110的中心轴线之间 的夹角暂时第定义为第一夹角，第二光反射元件212的反射面和光源腔2110的中心轴线之间的夹角暂时定义为第二夹角；通常情况下，由于配光组件210装配以及各元件的加工制作等误差，所以导致第一夹角与第二夹角之间往往会存在2-3°左右的偏差。
本申请实施例公开的配光组件210中，第一光反射元件213的反射面和第二光反射元件212的反射面可以均为平面，也可以均为向背离配光室的方向弯曲的曲面，其可以对平面或曲面的面型曲率进行相应的设计使反射光线按照要求的出光方向射出即可。
具体地，如图4所示，第一光反射元件213的反射面和第二光反射元件212的反射面均为向背离配光室的方向弯曲的曲面，且曲面为包括上弯折面和下弯折面的弯折曲面，从而通过上弯折面和下弯折面使得该弯折曲面具有两种面型曲率，进而使得经第二扩散部2112射出的光线中的大部分光线经下弯折面反射后从扩口端214射出、是形成蝙蝠翼配光的主要光线，小部分光线经上弯折板反射后也从扩口端214射出、对小角度方向的光线强度进行补强；因此，相较于平面的单一面型曲率，曲面可以达到更好的控光效果。
同时，作为弯折曲面的反射光线的一种出光方向要求，上弯折面的面型曲率设计为使得反射光线反射到15°以内(反射光线与光源中心轴线之间的夹角)的方向，下弯折面的面型曲率设计为使得反射光线反射到20°-30°之间的方向。
容易理解的是，本申请实施例公开的配光组件210中，为了更好地提高反射面的控光效果，第一光反射元件213的反射面和第二光反射元件212的反射面还可以设计为具有多个面型曲率的弯折曲面或平滑的弧形曲面；并且，根据具体的反射光线的光方向要求，反射面的面型曲率可以进行适应性的调整；本申请实施例不对第一光反射元件213的反射面和第二光反射元件212的反射面的具体形状以及反射面的具体面型曲率进行限制。
本申请实施例公开的配光组件210中，如图6所示，光源腔2110可以为 截面形状为方形的凹槽结构；相应地，凹槽的底面为第二扩散部2112，凹槽的两侧面分别为第一扩散部2111和第二扩散部2112。当然，光源腔2110还可以为其他形状的凹槽结构；例如，截面形状为弧形的凹槽结构(如图7所示)或截面形状为U形的凹槽结构等。
具体地，光源腔2110为三块光扩散板拼接形成的凹槽结构，并相应地作为第一扩散部2111、第二扩散部2112和第三扩散部2113。同时，作为第二扩散部2112的光线透过率的具体要求，第二扩散部2112的光线透过率可以为80％，从而使得第二扩散部2112的光通量占80％、第一扩散部2111和第三扩散部2113的光通率各占10％，进而使得光通量比例分配可以保证第一扩散部2111和第三扩散部2113射出的光通量在一个合理的范围内，这样有足够的光能量经过反射器反射而实现整灯需要的配光形状，同时又不至于经过第一光反射元件213和第二光反射元件212反射控光的光能量占比过大。作为光扩散板的具体规格尺寸要求，光扩散板的高度可以为12mm、宽度可以为31mm。
当然，光源腔2110也可以为两块或多块光扩散板拼接形成的凹槽结构，或者由一块光扩散板一体成型形成的凹槽结构；同时，根据具体地应用场景以及配光强度要求，可以对第一扩散部2111、第二扩散部2112以及第三扩散部2113的光线透过率的要求以及光扩散板的规格尺寸要求进行适应性调整。
优选地，第二扩散部2112可以设置有阵列排布的微结构21120，从而通过微结构21120可以对光源腔2110内射向第二扩散部2112的光线进行多角度的折射，进而经第二扩散部2112直接从扩口端214射出的光照更加均匀，使配光曲线更加圆润；其中，微结构21120可以为截面形状是三角形、弧形或圆形的凸棱或凹槽，还可以为圆形或锥形的凸起或凹坑等；同时，微结构21120可以设置于第二扩散部2112的内侧面(即位于光源腔2110内的一面)，也可以设置于第二扩散部2112的外侧面(即位于光源腔2110外的一面)或 第二扩散部内。当然，第二扩散部2112也可以为光滑的平面，即不设置微结构21120。
为了提高配光组件210在光扩散元件211的另外两个方向上(即光扩散元件211未设置第一光反射元件213和第二光反射元件212的两侧)的防眩光效果；本申请实施例公开的配光组件210还可以包括第一防眩光元件2301和第二防眩光元件2302；第一防眩光元件2301和第二防眩光元件2302分别设置于光扩散元件211相对的两侧，且第一防眩光元件2301和第二防眩光元件2302均位于第一光反射元件213和第二光反射元件212之间、并与第一光反射元件213和第二光反射元件212围成四周封闭的配光室，从而通过第一防眩光元件2301、第二防眩光元件2302、第一光反射元件213和第二光反射元件212在光扩散元件211四周均形成遮光角，使得配光组件210的UGR可以在16以下，达到较好的防眩光效果。其中，第一防眩光元件2301和第二防眩光元件2302可以均为镜面板或棱晶板等可以用于防眩光的光学元件。
具体地，作为第一防眩光元件2301、第二防眩光元件2302、第一光反射元件213和第二光反射元件212的遮光角的一种具体设置要求，第一防眩光元件2301和第二防眩光元件2302的遮光角为46.5°，第一光反射元件213和第二光反射元件212的遮光角为32°，从而可以提供更舒适地照明体验。当然，根据具体的使用场景可以对第一防眩光元件2301、第二防眩光元件2302、第一光反射元件213和第二光反射元件212的遮光角的设置进行适应性的调整，本申请实施例不限制各元件的遮光角的具体设置角度。
优选地，第一防眩光元件2301和第二防眩光元件2302位于配光室之内的侧面均为内侧面，第一防眩光元件2301的内侧面和第二防眩光元件2302的内侧面均为曲面，且曲面向背离配光室的方向弯曲，从而使得第一防眩光元件2301和第二防眩光元件2302的内侧面分别具有多种面型曲率，可以达到更好地控光效果。当然，第一防眩光元件2301和第二防眩光元件2302的内侧面也可以设计为平面，本申请实施例不限制第一防眩光元件2301和第二 防眩光元件2302的内侧面的具体形状。
本申请还公开了一种照明灯具，所公开的照明灯具包括光源板220以及上述的配光组件210；光源板220设置于光源腔2110的槽口处，且光源板220与光源腔2110对应的位置设置有发光元件2201，从而使得发光元件2201发出的光线可以通过配光组件210重新配光，并达到蝙蝠翼配光的效果。
通常，光源板220设置的发光元件2201可以为一组LED灯，一组LED包括至少一个发光二极管；同时，光源板220还设置有驱动器，并将驱动器与LED等电连接，从而通过驱动器可以使LED灯供电发光。
本申请实施例公开的照明灯具还可以包括壳体100，且壳体100设置安装槽110；光源板220设置于安装槽110的底面；配光组件210设置于安装槽110内、并位于光源板220上，且扩口端214位于安装槽110的槽口处；从而通过壳体100不仅可以对光源板220以及配光组件210等起到保护作用，而且还可以兼顾灯具的美观性；并且，壳体100还可以作为光源板220和配光组件210承载设置的基础构件，用于光源板220以及配光组件210的安装固定。
具体地，第一防眩光元件2301和第二防眩光元件2302均为镜面栅格元件230，且镜面栅格元件230呈V形；光源板220、光扩散元件211、第一光反射元件213和第二光反射元件212均沿安装槽110的长度方向延伸；镜面栅格元件230的数量可以为多个，并沿安装槽110的长度方向间隔设置，从而通过镜面栅格元件230将配光组件210分割形成多个配光单元200，即相邻的两块镜面栅格元件230之间为一个配光单元200，且一个镜面栅格元件230的两侧镜面可以分别作为相邻的两个配光单元200的第一防眩光元件2301和第二防眩光元件2302；同时，光源板220设置有与配光单元200一一对应的一组发光元件2201，从而使得每个发光元件2201发出的光线均可以经相应的配光单元200中的第一光反射元件213和第二光反射元件212的反射面重新配光、并达到蝙蝠翼的配光效果，从而有利于提高照明灯照的照度 均匀性；并且，在照明灯具多灯布置时可以减少照明灯具的布置数量，进而降低照明成本和提高光的利用率。
其中，镜面栅格元件230的数量具体可以为两个、三个、四个或五个等，相应地形成的配光单元200的数量为一个、两个、三个或四个等；本申请实施例不限制镜面栅格元件230以及配光单元200的具体数量。
镜面栅格元件230设置有供光扩散元件211通过的开口，从而光扩散元件211通过开口穿过各个镜面栅格元件230，且镜面栅格元件230的对称面垂直于光扩散元件211设置，开口的内侧边与光扩散元件211的表面贴合，从而便于通过镜面栅格元件230将配光组件210分割形成相应的配光单元200。
作为镜面栅格元件230的一种具体规格要求，镜面栅格元件230的高度为55mm，张开角度为14°。当然，根据具体使用要求可以对镜面栅格元件230的高度以及张开角度等具体规格进行适用性调整；同时，也可以对镜面栅格元件230的形状进行改变，例如梯形的镜面栅格元件230等；镜面栅格元件230可以为镜面铝栅格板或采用他材料制成的镜面栅格板；壳体100可以为铝制型材壳体，也可以为塑料或其他材料制成的壳体。

具体地，为了便于镜面栅格元件230与第一光反射元件213和第二光反射元件212的装配；第一光反射元件213和第二光反射元件212均设置有卡槽，镜面栅格元件230的两端分别设置有与卡槽相匹配的卡脚231，从而通过卡脚231与卡槽的卡扣配合，方便于镜面栅格元件230与第一光反射元件213和第二光反射元件212的装配固定；其中，卡脚231可以为凸起或柱状结构等。当然，镜面栅格元件230还可以通过粘结或紧固件等固定方式与第一光反射元件213和所述第二光反射元件212连接，实现镜面栅格元件230 的装配固定。
同时，为了便于第一光反射元件213和第二光反射元件212与壳体100的装配，可以在安装槽110的两侧壁设置沿安装槽110的长度方向延伸的插脚120，在第一光反射元件213和第二光反射元件212的背面设置沿安装槽110的长度方向延伸的插槽240，从而通过插脚120与插槽240的插接配合，方便于第一光反射元件213和第二光反射元件212与壳体100的装配固定。
当然，作为第一光反射元件213和第二光反射元件212与壳体100的其他装配方式，也可以将插槽240设置于安装槽110的两侧壁，将插脚120分别设置于第一光反射元件213和第二光反射元件212的背面；或者，第一光反射元件213和第二光反射元件212还可以通过螺钉等紧固件与壳体100固定连接等。
同时，镜面栅格元件230也可以直接设置于壳体100的安装槽110内，并且镜面栅格元件230直接与安装槽110的内壁连接、将安装槽110分割形成多个栅格，并在每个栅格中设置相应光源板220和第一光反射元件213和第二光反射元件212；本申请实施例不限制镜面栅格元件230的具体装配设置方式结构以及第一光反射元件213和第二光反射元件212与壳体100的具体设置方式结构。
