本实施例的照明设备还包括透镜50，透镜50安装在壳体10内，光源20通过透镜50产生非对称的出射光线，透镜50为对称结构，并具有中心对称面A0。透镜50包括：透镜本体51、进光部52、出光部53以及反射部54；进光部52设置于透镜本体51的第一表面并包括向透镜本体51的内部凹入且容纳光源20的安装凹部511，安装凹部511包括底壁以及连接在底壁边沿处的筒状侧壁；出光部53设置于透镜50的第二表面，第二表面平行于第一表面，其中，底壁包括外圈部以及位于外圈部的内部的中心部，外圈部朝向进光部52的方向凸出设置，中心部朝向出光部53的方向凸出设置；反射部54设置于透镜本体51的侧面并位于第一表面和第二表面之间。
底壁包括外圈部以及位于外圈部的内部的中心部，外圈部朝向进光部的方向凸出设置，中心部朝向出光部的方向凸出设置。光源20的出射光线通过朝向出光部的方向凸出设置的中心部时进行再分配，使照射在中心部底壁上的光束发散，能够产生一个非对称的出射光线，该非对称的出射光线经过出光板的中间区域，从而减小了出光板的中间区域的照度值，进而有利于提高出光板上的照度的均匀度，以在光路方向上使用户获得较好的视觉体验。因此， 本实施例的技术方案有效地解决了相关技术中的光路通过透镜集中地经过出光板的中间区域，使得出光板上的照度不均匀的问题。上述的反射部54能够将从筒状侧壁入射的光线反射至出光部，使得从筒状侧壁入射的光线均能从出光部出射，避免了上述光线直接从反射部54所在的面出射导致的光线损耗。
需要说明的是，上述的外圈部与中心部直接连接，上述的外圈部由多个曲面沿筒状侧壁的周向依次拼接而成。第二表面和第一表面均可以是平面或者是弧面。第二表面平行于第一表面是指第二表面与第一表面之间的夹角在0至5度的范围内。
在图中未示出的实施例中，外圈部包括朝向进光部的方向凸出设置的多个环状部，多个环状部由筒状侧壁至中心部的方向依次连接，中心部包括朝向出光部的方向凸出设置多个凸出部，多个凸出部沿外圈部的周向依次连接。出射光线通过朝向出光部的方向凸出设置的多个环状部以及多个凸出部时进行多次再分配，使照射在中心部底壁上的光束有效地发散，能够产生一个非对称且不规则的出射光线，该非对称且不规则的出射光线经过出光板的中间区域，进而有效地减小了出光板的中间区域的照度值。需要说明的是，上述的环形部可以是圆形或者椭圆形或者波浪形或者多边形。
为了进一步说明光源20的出射光线通过中心部时进行再分配的效果，本申请提供了相关技术中光源透过透镜50照射在瑞丽散热板上的效果图进行对比说明。
具体地，参照图1至图3，相关技术中的透镜50包括向透镜本体的内部凹入且容纳光源的安装凹部，安装凹部具有朝向光源凸出设置的弧形凹面，光源透过该弧形凹面的中心位置时，弧形凹面的中心位置附近的光束凝聚(参见图2)。而在本申请中，参照图8和图9，光源20的出射光线通过中心部时，中心部的光束发散(参见图9)。这样，本实施例的朝向出光部的方向凸出设置的中心部能够促进中心部的光束发散、从而减小出光板的中间区域的照度值，有利于促进出光板上的均匀度。
需要说明的是，图1和图2中光束凝聚的效果为实际仿真结果。图8和图9中光束发散效果为实际仿真结果。
如图5至图7以及图10所示，光源20的中心在安装凹部511的开口处形成中心光点A1。中心部包括中点A2，设定经过中点A2和中心光点A1的连线为中线L0。筒状侧壁包括相对于中心对称面A0对称设置的第一侧壁和第二侧壁，第一侧壁和第二侧壁在中心对称面A0内形成第一相交线L14和第二相交线L25。外圈部在中心对称面A0内形成的位于中心部两侧的第一曲线L01和第二曲线L02。中心部在中心对称面A0内形成与第一曲线L01相连的第三曲线L03以及与第二曲线L02相连的第四曲线L04。
为了具体分析光源20的出射光线通过中心部时，中心部的光束发散的工作原理，以第三曲线L03和第一曲线L01为例。如图5和图10所示，具体分析如下：
中心光点A1点处入射光线为A1A2，出射光线为A2e。
第一曲线L01点处的切线为aA2b，中点A2处的法线为cA2d。
所以，中点A2处入射光线A1A2的入射角为∠A1A2d，出射光线A2e的出射角为∠cA2e。
假定透镜50的材料折射率为Rf，则根据斯涅尔定律Rf×sin∠cA2e＝sin∠A1A2d。
而透镜所用材料(如塑胶或者玻璃)的折射率Rf恒定＞1。所以，经过简单计算可以得到：∠cA2e＜∠A1A2d，即出射角小于入射角。相应地，出射光线A2e偏离了入射光线A1A2所在A2z轴。即中点A2靠近第一曲线L01附近的光束发散了。
经过上述相似地推理可以得到：中点A2靠近第二曲线L02处的出射光线会偏离入射光线所在A2z轴，并且经过第一曲线L01的出射光线与经过第二曲线L02的出射光线分布在A2z轴的两侧，即中心部处的光束发散了。
如图5至图7以及图10所示，在本实施例中，第一曲线L01与第一相交线L14相交于第一交点B1，中心光点A1与第一交点B1的连线为第一直线L1。中线L0与第一直线L1之间形成第一夹角。第二曲线L02与第二相交线L25相交于第二交点B2，中心光点A1与第二交点B2的连线为第二直线L2。中线L0与第二直线L2之间形成第二夹角，第一夹角大于第二夹角。这样，使得第一曲线L01及第三曲线L03所对应出射光线覆盖的出光板的长度(线段pq的长度)大于第二曲线L02及第四曲线L04所对应出射光线覆盖的出光板的长度(线段mp的长度)，使得出光板的远端方向上有更多的光线能量，有利于增加照度，使得出光板在长度方向上的照度变得均匀。上述的出光板的远端是指出光板的远离光源20的一端。
发明人发现，由于在实际应用中透镜50的尺寸远远小于透镜50与出光板之间的距离，所以在分析的过程中可以近似将透镜简化为一个光源20。对于第一夹角大于第二夹角的技术效果说明具体分析如下：
如图11所示，A1点为光源20的中心光点位置，mpq是出光板的位置，其中，m为出光板的近端，q为出光板的远端。A1np是光源20的光轴方向，光轴A1np与A1sq之间的光线对应于图7中的第一曲线L01及第三曲线L03，光轴A1np于A1m之间的光线对应于图7中的第二曲线L02及第四曲线L04。假定∠qA1p＝∠pA1m＝α，即这里先假定第一夹角等于第二夹角。
又假定∠A1qp＝θ，在△spq中pq＝sp/sin(θ)，在△A1sp中sp＝A1p×sin(α)，所以pq＝A1p×sin(α)/sin(θ)。
在△mnp中mp＝mn/sin(∠npm)，对于△A1pq，∠npm＝∠pA1q+∠pqA1＝α+θ。
所以mp＝mn/sin(α+θ)。
在△mA1n中mn＝A1m×sin(α)。
所以，mp＝A1m×sin(α)/sin(α+θ)。
所以pq/mp＝(A1p/A1m)×(sin(α+θ)/sin(θ))。
简单推理可以得到A1p＞A1m，所以A1p/A1m＞1。
又显然sin(α+θ)/sin(θ)＞1。
所以pq/mp＞1，即pq＞mp。
也就是说在∠qA1p＝∠mA1p＝α的情况下，∠qA1p所对应出射光线覆盖的出光板的长度(线段pq的长度)要大于∠mA1p所对应出射光线覆盖的出光板的长度(线段mp的长度)。即经图7示出透镜50的第一曲线L01及第三曲线L03出射的光线所覆盖的出光板长度要大于经图7示出透镜50的第二曲线L02及第四曲线L04出射的光线所覆盖的出光板长度。
如图10所示，如果假定第一夹角等于第二夹角，对应的出光板长度pq与出光板长度mp来源的光线能量相等。且pq＞mp，使得出光板长度pq上的照度要小于出光板长度mp上的照度。但在本实施例中，如图7所示，由于第一夹角大于第二夹角，使得出射的光线在图10示出的出光板长度pq上，能够增加照度，使得出光板的远端方向上有更多的光线能量，有利于提高整个出光板mpq上的照度的均匀度。
如图7所示，为了便于出模，容易加工成型，第一相交线L14与第一垂面之间形成第三夹角，第一垂面垂直于第一表面，第三夹角的范围在2°至5°之间。第三夹角优选为2°或者3°或者4°或者5°。
如图7所示，为了便于出模，容易加工成型，第二相交线L25与第二垂面之间形成第四夹角，第二垂面垂直于第一表面，第四夹角的范围在2°至5°之间。第四夹角优选为2°或者3°或者4°或者5°。
当然，在图中未示出的实施例中，第一相交线L14与第一垂面之间形成第三夹角，第一垂面垂直于第一表面，第三夹角的范围可以在2°至5°之间。或者第二相交线L25与第二垂面之间形成第四夹角，第二垂面垂直于第一表面，第四夹角的范围可以在2°至5°之间。
如图5至图7所示，反射部54包括相对于中心对称面A0对称设置的第一弧形面和第二弧形面。第一弧形面和第二弧形面在中心对称面A0上形成第三相交线L38和第四相交线L69。第一弧形面和第二弧形面共同形成透镜50的全反射面。该全反射面是照明光学领域的常用的概念，本申请对全反射面的内涵不再做解释。
参照图11，根据第一夹角大于第二夹角的技术效果可知，增加出光板的远端q方向上的光线能量，有利于提升整个出光板mpq上的照度的均匀度。
如图12所示，透镜50的全反射面的第三相交线L38和第四相交线L69处的出射光线都投射至靠近出光板mq(即图11中的mpq)的远端q附近，能够增加出光板mq的远端q方向上的光线能量以增加出光板mq远端q的照度，进而有利于提高整个出光板mq的照度的均匀度。
发明人发现，为了实现透镜的全反射面的第三相交线L38和第四相交线L69处的出射光线都投射至靠近出光板mq的远端q附近这一目标，透镜的两个第三相交线L38和第四相交线L69具有以下特点：
如图13所示，第三相交线L38的长度大于第四相交线L69的长度。第三相交线L38与第一表面相交成第三交点B3，设定经过第三交点B3作第三相交线L38的切线为第一延伸线L3v。第四相交线L69与第一表面相交成第四交点B4，设定经过第四交点B4作第四相交线L69的切线为第二延伸线L6u。其中，第一延伸线L3v与中线L0之间形成第五夹角，第五夹角大于或者等于45°。第五夹角优选45°或者51°或者56°或者60°。第二延伸线L6u与中线L0之间形成第六夹角，第六夹角小于或者等于45°。第六夹角优选为45°或者42°或者36°或者30°。上述的第五夹角的点值和第六夹角的点值能够实现透镜的全反射面的第三相交线L38和第四相交线L69处的出射光线都投射至靠近出光板mq的远端q附近，使出射光线更好的覆盖在出光板mq上。
具体地，下面分析全反射面上的第三相交线L38处的出射光线的工作原理：
如图13和图14所示，为了增加出光板mq远端q的照度，需要增加透镜出射光线向出光板mq远端q的投射。这里约定实际应用时出光板长度mq(即线段mq的长度)远大于透镜的尺寸。可以将光源20简化为一个的中心光点A1。对于第三相交线L38处的全反射面来说，图14示出B3点处出射光线B3h与中线L0不相交的情形，有助于促使出射光线投射向出光板mq的远端q，从而提升整个出光板mq上的照度的均匀度。并由图14可知，∠A1B3h为钝角，即∠A1B3h＞90°。∠A1B3h具体数值计算如下：
如图14所示，hq为点B3的出射光线B3h经过第二表面折射后的透镜外部光线路径，hq与中线L0的夹角约定为δ 2。
如图14所示，B3h为外部光线路径hq在透镜内对应的光线路径，线段B3h与中线L0的夹角约定为δ 1。如图14所示，根据菲涅尔折射定律，sin(δ 1)＝sin(δ 2)/Rf，如前所做假定Rf为透镜的材料的折射率为大于1的正常数。
如图14所示，∠A1B3h＝∠A1B3w+∠wB3h。这里约定B3w平行中线L0，所以∠A1B3w＝90°。又∠wB3h＝δ 1，所以∠A1B3h＝90°+δ 1。
假定线段A1B3k是∠A1B3h的角平分线，A1B3是第三相交线L38的起始点8点处的入射光线，B3h是B3点处的出射光线，A1B3与B3h关于B3k对称，使得B3k也是B3点处的法线。根据前面的叙述，线段B3v为B3点的切线，而线段B3k是B3点处的法线，使得线段B3v垂直于线段B3k。即：
∠vB3A1+∠A1B3k＝90°。所以∠vB3A1＝90°-∠A1B3k。
又线段3k是∠A1B3h的角平分线，∠A1B3k＝0.5×∠A1B3h＝0.5×(90°+δ 1)。
所以∠vB3A1＝90°-∠A1B3k＝90°-0.5×(90°+δ 1)＝0.5×(90°-δ 1)。
线段A1B3在第一表面内，所以根据前面的叙述，线段A1B3垂直于中线L0。所以，∠vA1B3＝90°。根据三角形三个内角和等于180°,所以在△vB3A1中，
∠A1vB3+∠vB3A1＝90°。
所以∠A1vB3＝90°-∠vB3A1＝90°-0.5×(90°-δ 1)＝0.5×(90°+δ 1)＞0.5×90°＝45°。
具体地，下面分析全反射第四相交线L69处的出射光线的工作原理：
为了增加出光板mq远端q的照度，需要增加透镜出射光线向出光板mq远端q的投射。这里约定实际应用时出光板长度mq(即线段mq的长度)远大于透镜的尺寸。可以将光源20简化为一个的中心光点A1。对于第四相交线L69处的全反射面来说，图15示出B4点处出射光线B4j与中线L0相交的情形，有助于促使出射光线投射向出光板mq的远端q，从而提高整个出光板mq上的照度的均匀度。并由图15可知，∠A1B4j为锐角，即∠A1B4j＜90°。∠A1B4j具体数值计算如下：
如图15所示，jr为B4点的出射光线B4j在经透镜的第二表面折射后出射的透镜外部光线路径，jr与中线L0的夹角约定为γ 2。
如图15所示，B4j为出射光线路径jr在透镜内对应的光线路径，这里约定B4x平行中线L0，所以B4j与中线L0的夹角等价于B4j与B4x的夹角，即∠jB4x。这里约定为∠jB4x＝γ 1。如图15所示，根据菲涅尔折射定律，sin(γ 1)＝sin(γ 2)/Rf，如前所做假定Rf为透镜的材料的折射率为大于1的正常数。
如图15所示，∠A1B4j＝∠A1B4x-∠jB4x。而B4x平行中线L0，所以∠A1B4x＝90°。又∠jB4x＝γ 1，所以∠A1B4j＝90-γ 1。
假定线段B4i是∠A1B4j的角平分线，A1B4是B4点处的入射光线，B4j是B4点处的出射光线，A1B4与B4j关于B4i对称，使得B4i也是B4点处的法线。根据前面的叙述，线段B4u为B4点的切线，而线段B4i是B4点处的法线，使得线段B4u垂直于线段B4i。即：
∠uB4A1+∠A1B4i＝90°。所以∠uB4A1＝90°-∠A1B4i
又线段B4i是∠A1B4j的角平分线，∠A1B4i＝0.5×∠A1B4j＝0.5×(90°-γ 1)。
所以∠uB4A1＝90°-∠A1B4i＝90°-0.5×(90°-γ 1)＝0.5×(90°+γ 1)。
线段B4A1在第一表面内，所以根据前面的叙述，线段B4A1垂直于中线L0。所以，∠uA1B4＝90°。根据三角形三个内角和等于180°,所以在△uB4A1中，
∠A1uB4+∠uB4A1＝90°。
所以∠A1uB4＝90°-∠uB4A1＝90°-0.5×(90°+γ 1)＝0.5×(90°-γ 1)＜0.5×90°＝45°。
如图5、图7以及图13所示，反射部54包括相对于中心对称面A0对称设置的第一弧形面和第二弧形面，第一弧形面和第二弧形面在中心对称面A0上形成第三相交线L38和第四相交线L69。其中，第四相交线L69包括第一交线段L67以及与第一交线段L67连接的第二交线段L79，第一交线段L67比第二交线段L79更靠近第一表面。第三相交线L38的长度大于第一交线段L67的长度。为了便于设计及出模，第二交线段L79平行于中线L0。
当然，在图中未示出的实施例中，第二交线段L79倾斜于中线L0。
如图13至图15所示，为了使透镜实现偏心散光，让倾斜打到出光板的近端的光线和远端的光线尽可能均匀一些，第三相交线L38与第二表面相交于第五交点8(即上述起始点8)，第二交线段L79与第二表面相交于第六交点9，第六交点9与中线L0之间的距离小于第五交点与中线L0之间的距离。
如图13至图15所示，为了便于将第三相交线L38和第一相交线L14位于中线L0的同一侧，四相交线L69和第二相交线L25位于中线L0的同一侧。这样，使得出光板的远端方向上有更多的光线能量，有利于增加照度，使得出光板在长度方向上的照度变得均匀。
本申请还提供了一种照明设备，如图16至图21所示，照明设备包括光源20和透镜50，透镜为上述的透镜。由于上述的透镜能够解决相关技术中的光路通过透镜集中地经过出光板的中间区域，使得出光板上的照度不均匀的问题，使得包括该透镜的照明设备能够解决同样的技术问题。需要说明的是，本实施例的照明设备为天空灯，出光板为瑞利散射板。当然，在图中未示出的实施例中，照明设备还可以为格栅灯或者洗墙灯或者台上照明或者厨卫灯。出光板还可以为混光板或者出光罩或者出光面板。
如图16至图21所示，照明设备还包括壳体10和出光板30，光源20和透镜50均安装在壳体10内，壳体10包括顶板11和围板12，围板12的第一端与顶板11连接，围板12的第二端形成出光口，出光板30设置在出光口处，顶板11与出光口所在平面平行设置，围板12的中心线与顶板11倾斜设置，光源20设置在围板12和顶板11之间的锐角夹角处。这样光源20能够进行倾斜出射光线，从而在保证光线照射到出光板的光程的前提下，尽可能地降低了壳体厚度。
如图16至图21所示，照明设备还包括壳体10。光源20和透镜50均安装在壳体10内。设定经过光源20的中心光点A1并垂直于地面的直线为垂轴C1，设定光源20的中心光点A1穿过壳体10时形成出射光束主光线C2(图18中示出)。垂轴C1与出射光束主光线C2之间形成第七夹角θ，第七夹角θ的范围在45°至80°之间。位于45°至80°范围内的第七夹角θ使光源20可以合理地安装在壳体10内，以使垂轴C1的长度越来越短，使得壳体10的厚度越来越薄，有利于降低照明设备的加工成本。第七夹角θ的范围优选在45°至60°之间，第七夹角θ优选为45°或者60°或者72°或者80°。
需要说明的是，上述的出射光束主光线是指：光源与透镜出射光束中最大光强值所在的方向即为出射光束主光线所在方向。采用最大光强值所在方向来定义光束主光线方向的原因 在于出射光束在最大光强方向的光线投射能力最强，可以用来表征光源与透镜出射光束的投射方向。最大光强值可以由光度分布计测量。
发明人发现，光源20位于壳体10内的位置不同，所照射的光路也不同，使得覆盖在出光板的照射范围也不同，具体分析如下：在图16中，W1为前墙侧，W2为后墙侧，W3为地面侧，W4为天花侧。
当θ增大时，出射光线整体会向图16中的前墙侧移动，相应的出射光线落在图16中的地面侧的比例就会减小。所以θ有一优选的上限值θ max。优选地，θ max≤80°。
又如图17所示，假定A1p方向是出射光束主光线所在方向。∠fA1p＝θ。A1m和A1q是出射光束的边界光线所在方向。∠mA1p＝α，∠pA1q＝β。其中，α、β均为数值恒定的正常数。在△fA1m中，fm＝A1f×tan(∠fA1m)＝A1f×tan(∠fA1p-∠mA1p)＝A1f×tan(θ-α)。在△fA1q中，fq＝A1f×tan(∠fA1q)＝A1f×tan(∠fA1p+∠pA1q)＝A1f×tan(θ+β)。
所以，光源与透镜出射光束能覆盖的照射范围，即光源与透镜出射光束能覆盖的出光板的照射范围：mq＝fq-fm＝A1f×(tan(θ+β)-tan(θ-α))。
mq对θ进行数学求导操作：
d(mq)/dθ＝A1f×((1/cos 2(θ+β))-(1/cos 2(θ-α)))
又对于本申请，约定只考虑以下应用情形：
0°＜θ-α＜90°，
0°＜θ+β＜90°。
又显然θ-α＜θ+β，所以：0°＜θ-α＜θ+β＜90°。
所以cos(θ-α)＞cos(θ+β)，所以(1/cos 2(θ-α))＜(1/cos 2(θ+β)。
所以((1/cos 2(θ+β))-(1/cos 2(θ-α)))＞0。
所以d(mq)/dθ＞0，也就是说当θ增加mq也相应增加，也就是说大θ值是有利于增加光源与透镜出射光束对出光板的照射范围的。需要说明的是，在本申请的实际应用中出光板的照射范围mq是相对确定的，而θ越大、对应A1f就越小。而A1f对应的是壳体10的厚度。也就是说，大的θ值有利于减小壳体10的厚度。所以θ值有一优选的下限值θ min。优选地，θ min≥45°。
如图8、图9和图13所示，反射部54包括相对于中心对称面A0对称设置的第一弧形面和第二弧形面，第一弧形面和第二弧形面在中心对称面A0上形成第三相交线L38和第四相交线L69，第三相交线L38比第四相交线L69更靠近顶板11，第三相交线L38的内侧朝向出光板30。这样，能够保证第三相交线L38所在的反射部54能够有效地进行全反射。
发明人发现，由于光源20需要将光打到瑞利散射板的边缘处，以实现瑞利散射板发光均匀，避免出现明显暗光区域。但将光打到瑞利散射板边缘时，不可避免的会有部分光线照射到与瑞利散射板相邻的壳体内表面边上，此时会产生大量的杂散光线进入瑞利散射板，进而在壳体内产生有害的反光，影响照明设备的出光效果。
为了解决上述问题，如图8、图20至图22所示，本实施例的照明设备还包括设置在壳体10内的减反射结构40，减反射结构40位于透镜50射出的光线的路径的一侧。减反射结构40用于吸收入射光线中的杂散光线，减少杂散光线反射至出光板上。进而能够极大地降低由壳 体10内产生的有害的杂散光或者有害的反光，有效地保证了照明设备的出光效果。具体地，壳体10包括顶板11以及连接在顶板11四周的围板12，减反射结构40设置在围板12顶板11上，当然，减反射结构还可以是设置在围板12上。
如图20和图21所示，照明设备还包括壳体10，光源20和透镜50均安装在壳体10内，壳体10包括围板12和连接在围板12的一端的顶板11，围板12的中心线与顶板11倾斜设置，减反射结构40设置在围板12的内壁的受光区域上。需要说明的是，上述的受光区域是指光源出射的部分光线能够直射到围板的内壁的区域。当然，减反射结构40除了设置在上述区域外，还可以设置在围板的内壁的其他的区域。当然也可以设置在顶板的内壁上。
并且，减反射结构40设置在围板12的内壁的受光区域上能够消除有害的反光，无需将壳体的外形扩大用于避让来消除有害的反光，同时满足了照明设备小型化、模块化的量产需求。
具体地，如图20所示，围板12依次连接的第一侧板、第二侧板、第三侧板以及第四侧板，第一侧板、第二侧板、第三侧板以及第四侧板均与顶板11连接，第一侧板和第三侧板平行设置且均为平行四边形结构，第二侧板和第四侧板平行设置，光源20与第二侧板之间的距离小于光源20与第四侧板之间的距离。第一侧板和第三侧板的形状为平行四边形，第二侧板和第四侧板为矩形，这样使得围板12的竖直截面为平行四边形，这样能够有效地增加光源20与出光口之间的光学距离，同时，上述的形状便于后续的装配。减反射结构40设置在第四侧板上。这样，第四侧板与光源20的出射的光线相对应，便于第四侧板上的减反射结构40能够直接吸收部分光线，减少杂散光线反射至第一侧板、第二侧板或者第三侧板上。
如图23所示，减反射结构40包括蜂窝层。相比于普通板材如槽钢而言，蜂窝层的内部能够折射更多的杂散光线，有效地对杂散光线进行捕捉并吸收掉。
如图23和图24所示，蜂窝层包括相互连接的多个筒体。每个筒体为正六边形的柱状体，多个正六边形柱状体通过边界重合，相互连接成蜂窝层。需要说明的是，每个筒体的形状可以不限于正六边形的柱状体，还可以是四边形的柱状体、五边形的柱状体、七边形的柱状体及以上。
如图24至图26所示，为了蜂窝层更好地吸收入射光线中的杂散光线，蜂窝层包括相互连接的多个筒体，每个筒体的轴线垂直于壳体10的内侧壁面。相邻的两个筒体之间具有间距L，每个筒体的高度H与间距L之比大于1。为了降低高度、成本，高度H选值较小，所以相应的间距L选值也较小。应用时选择间距L比较小的情况，例如L为2mm。减反射结构40的所有表面均涂有黑色层。上述的壳体10的内侧壁面优选为壳体10顶板11的内壁面，当然，在图中未示出的实施例中，壳体的内侧壁面还可以是围板12的内壁面。
具体地，每个筒体吸收入射光线中的杂散光线的原理如下：
图26中矩形a2b2c2d2表征正六边形柱状体沿高度H方向的截面。光源20的中心光点A1点代表照明设备的安装位置，代表光线的起点。图25中的A1a3是投射向筒体内壁面的光线，从入光口a2b2进入正六边形的柱状体以后，大部分被黑色的内壁吸收，剩下的少部分的光线在a3点反射后形成有一定发散角度反射光束，反射光束的中心方向光线为a3c3。a3b3和a3d3是反射光束的两条边界光线。如图26所示，反射光束会走向正六边形的柱状体的底部c2d2方向，在上述关系式H/L＞1的作用下，反射光束会再次或多次继续入射到正六边形的柱状体的内侧壁。在经过再次或多次的反射后，入射光线A1a3会被正六边形的柱状体的黑色内壁面吸收掉，而不会反射出去。
如图22所示，为了使减反射结构40具有较高的结构强度，减反射结构40为金属件。这样，金属件使得减反射结构40的自身不易变形，避免干扰到正常入射光线，能够保证减反射结构40吸收部分入射光线的效果。
如图20和图21所示，照明设备还包括壳体10和出光板30，光源20和透镜50均安装在壳体10内，出光板30设置在壳体10内，出光板30位于透镜50射出的光线的路径上。出光板30在面向光源20的一侧贴合有一层带微结构的膜层。该膜层具有带光点遮蔽能力的微结构膜。上述的膜层优选为美国的Bright View膜(高亮屏扩散膜)、Luminit膜(光学薄膜)。通过膜贴合工艺将Bright View膜贴合到出光板的面向光源的一侧。经过实际验证，贴合了带光点遮蔽能力的微结构膜的出光板对光源和透镜进行光点隐藏处理，使得隐藏效果大幅提升，视觉效果得到大幅地改善。
如图27至图36所示，在本实施例中，照明设备包括：壳体10、光源20以及出光板30。壳体10上设置有出光口。光源20设置于壳体10内。出光板30设置于出光口处。其中，光源20的主出光方向与出光口所在平面之间成锐角夹角a，锐角夹角a在10°至60°之间。
应用本实施例的技术方案，光源20设置在壳体10的内部，壳体10上设置有出光口，出光板30设置在出光口处。光源20的出光方向与出光口所在的平面之间成锐角夹角。通过上述的设置能够有效地提高光源20到出光口之间的光学距离，这样能够在保证整体照明设备的尺寸的前提下，保证照明设备实现自然光的照射效果，因此本实施例的技术方案有效地解决了相关技术中的照明产品难以实现自然照射效果的问题。
如图27至图36所示，本实施例的照明设备包括吸顶灯、面板灯、青空灯、厨卫集成类灯具。出光板30包括混光板、出光罩或者瑞利散射板等。
如图27至图36所示，在本实施例中，壳体10包括顶板11以及围板12，围板12的第一端与顶板11连接，出光口设置在围板12的第二端，围板12的中心线与顶板11倾斜设置，光源20设置于顶板11或者围板12上，光源20位于顶板11和围板12的夹角处。由于围板12倾斜设置，这样能够进一步增加光源20到出光口之间的光学距离，进而能够进一步地提高自然照射的效果。具体地，在本实施例中，光源20设置在围板12和顶板11之间的锐角夹角处。
在图中未示出的实施例中，光源设置于围板上，并靠近顶板和围板的夹角处。
如图27至图36所示，在本实施例中，围板12包括依次连接的第一侧板121、第二侧板122、第三侧板123以及第四侧板124，第一侧板121、第二侧板122、第三侧板123以及第四侧板124均与顶板11连接，第一侧板121和第三侧板123平行设置且均为平行四边形结构，第二侧板122和第四侧板124平行设置，上述的设置能够使得光源20的光线长度较大，进而使得照射的效果较好。
如图27至图36所示，在本实施例中，光源20与第二侧板122之间的距离小于光源20与第四侧板124之间的距离，和/或，光源20与顶板11之间的距离小于光源20与出光口之间的距离。第一侧板121和第三侧板123的形状为平行四边形，第二侧板122和第四侧板124为矩形，这样使得围板12的竖直截面为平行四边形，这样能够有效地增加光源20与出光口之间的光学距离，同时，上述的形状便于后续的装配。
在图中未示出的实施例中，光源与顶板之间的距离小于光源与出光口之间的距离。
如图27至图36所示，在本实施例中，照明设备还包括减反射结构40，出光板30为瑞利散射板，其中，减反射结构40至少设置于第四侧板124上，和/或，减反射结构40位于光源 20的照射方向上。减反射结构40位于光源20的照射方向上，减反射结构40的设置能够避免照明设备出现过亮的区域，进而影响照射的效果。
在图中未示出的实施例中，消光板还可以在第二侧板、第三侧板以及第四侧板上均设置。
如图27至图36所示，在本实施例中，减反射结构40上设置有蜂窝结构，蜂窝结构包括相互连接的多个筒体，其中，每个筒体的内孔的边长与每个筒体的高度之比大于或者等于1，和/或，每个筒体的高度在0.5mm至10mm的范围内，和/或，每个筒体的颜色为黑色。上述的蜂窝结构为微型结构，具有0.5mm至10mm的深度。当光源20发出的光照射在蜂窝结构的上侧，而视线是从出光口进入的，看到的蜂窝结构的下侧，这样则能够使得用户无法看到光线的照亮区域，反映的视觉效果即为黑色。蜂窝结构包括相互连接的多个筒体，每个筒体的横截面呈正六边形。当然在图中未示出的实施例中，每个筒体的横截面的形状可以不限于正六边形，还可以是四边形、五边形、七边形及以上。每个筒体的内孔的边长与每个筒体的高度之比大于或者等于1。每个筒体的颜色为黑色。每个筒体的内孔的边长在0.5mm至15mm的范围内。每个筒体的内孔的边长优选为0.5mm或者1mm或者5mm或者10mm或者15mm。每个筒体的高度在0.5mm至10mm的范围内。同时为了降低高度及成本，高度选值较小，所以相应的间距选值也较小。应用时选择间距比较小的情况，例如为2mm。
如图27至图36所示，在本实施例中，减反射结构40包括消光涂层，消光涂层包括高耐候氟碳漆或者醇酸磁漆或者耐高温油漆或者环氧防腐漆，和/或，消光涂层为黑色涂层。上述的设置均能够实现消光的效果。
如图27至图36所示，在本实施例中，减反射结构40还包括消光涂层。消光涂层包括高耐候氟碳漆或者醇酸磁漆或者耐高温油漆或者环氧防腐漆。其中，高耐候氟碳漆属于丙烯酸防腐涂料，醇酸磁漆和耐高温油漆均属于油性漆，环氧防腐漆属于水性漆。消光涂层为黑色涂层。
如图27至图36所示，在本实施例中，光源20包括PCB板21和多个灯珠22，多个灯珠22形成一排设置于PCB板21上，其中，灯珠22通过导电压接件连接在PCB板21上，导电压接件的第一端与PCB板21连接，导电压接件的第二端压设在灯珠22的侧边，导电压接件包括导线部和设置于导线部上的加强部，导线部包括位于中部的弯曲段和位于两端的平直段，加强部套设在弯曲段外，弯曲段朝向PCB板21设置，加强部设置于弯曲段，加强部的底面为平面，加强部的底部与PCB板21抵接配合。上述的设置能够保证光源20的照射方向，避免有较多的灯珠22发出的光直接照射到出光口处。灯珠22为COB灯珠。
如图27至图36所示，在本实施例中，PCB板21上设置有安装区域，灯珠22设置在安装区域处。灯珠22通过导电压接件连接在PCB板21上，导电压接件的第一端与PCB板21连接，导电压接件的第二端压设在灯珠22的侧边。上述的导电压接件一方面能够实现灯珠22的电路的导通，另一方面能够实现对灯珠22的固定，这样使得灯珠22的位置稳定。通过上述的设置能够有效地减少连接导线的使用，避免连接导线散落在灯珠22的附近而影响照明效果。同时由于上述的灯珠22无需其他结构进行固定，仅通过导电压接件就能够实现对灯珠22的固定，这样有效地降低了灯体组件的整体的结构复杂度，并且也降低了其他结构对发光效果的影响的可能性。
如图27至图36所示，在本实施例中，灯珠22通过导电压接件连接在PCB板21上，导电压接件的第一端与PCB板21连接，导电压接件的第二端压设在灯珠22的侧边，导电压接件包括导线部和设置于导线部上的加强部，导线部包括位于中部的弯曲段和位于两端的平直段，加强部套设在弯曲段外，弯曲段朝向PCB板21设置，加强部设置于弯曲段，加强部的底面为平面，加强部的底部与PCB板21抵接配合。导电压接件包括导线部和设置于导线部上的 加强部。加强部的设置能够进一步提高导电压接件的强度，避免导电压接件弯曲而影响灯珠22的固定效果。导线部包括位于中部的弯曲段和位于两端的平直段，加强部套设在弯曲段外。弯曲段的设置能够提高导线部的结构强度，并且由于弯曲段是朝向PCB板21设置的，这样能够有效地提高导线部的反向抗弯曲的能力，这样能够使得灯珠22的固定效果更好，同时将加强部设置在弯曲段，这样能够进一步保证导线部的结构强度。加强部的底面为平面，加强部的底部与PCB板21抵接配合。加强部的底部与PCB板21抵接配合，这样能够提高导电压接件的稳定性，进而能够进一步提高灯珠22的稳定性。具体地，在本实施例中，加强部为长方体，当然，还可以为正方体，其他形状的六面体，或者是圆柱体、圆锥体以及棱锥体等。导线部的材质为铜，导线部的拉伸强度在400N/mm 2-450N/mm 2之间，加强部的材质为铜。上述的导线部的材质为铜，这样使得导电的效果较好。并且导线部的拉伸强度较大，这样能够避免导线部发生变形。本实施例的技术方案将COB灯珠的“+”“-”极通过导电压接件表贴引出，为透镜50贴装留下足够空间，不存在影响发光效果的现象，导电压接件可以引出多个COB灯珠的“+”“-”极至PCB板21后，PCB板21通过印制线统一至1个端子然后输出到电源，解决传统接线整理接出问题、连接线与铝基板短路问题；由于PCB板21和COB灯珠通过导电压接件连接，COB灯珠不需要独立进行固定，直接将印制板固定于PCB板21，取消了螺丝固定COB灯珠的过程。
如图27至图36所示，在本实施例中，透镜50为多个，多个透镜50与灯珠22一一对应地设置。透镜50的结构简单，便于装配，能够有效地实现光源的聚焦。
如图27至图36所示，在本实施例中，第一侧板121和第三侧板123相对应的表面为光滑面。第四侧板124朝向第二侧板122的表面上设置有第一加强结构71，第一侧板121和第三侧板123的外表面设置有第二加强结构72。第一加强结构71和第二加强结构72的结构简单，便于设置。第二加强结构72位于围板12的外侧，这是由于光源20在进行照射时，若将第二加强结构72设置在围板12的内侧，光源20发出的光能够照射在第二加强结构72，这样会形成过亮的区域，进而影响了照射的效果，所以这也是将第一侧板121和第三侧板123的相应的表面设置为光滑面的原因。而将第一加强结构71设置在围板12的内侧，是由于第一加强结构71是位于光源20的后侧，光源20发出的光不会照射在第一加强结构71上，所以并不影响照射的效果。
如图27至图36所示，在本实施例中，照明设备还包括封框80，封框80安装于出光口处，出光板30位于封框80和壳体10之间。封框80的设置能够更好地固定出光板30，并能够提高照明设备的密封效果，还可以与其他的连接结构配合。
如图27至图36所示，在本实施例中，照明设备还包括散热件60，散热件60设置于顶板11上，光源20设置于散热件60上，散热件60包括固定板61和与固定板61连接的倾斜板62，光源20设置于倾斜板62上，固定板61与顶板11贴合连接。散热件60能够有效地固定光源20，由于散热件60上设置有倾斜板62，将光源20设置在倾斜板62上，则实现了光源20的出光角度与出光口之间倾斜设置。同时，散热件60能够有效地对光源20进行散热，防止光源20的温度过高而影响光源20的正常使用。
在图中未示出的实施例中，散热件还可以设置在围板上。
如图27至图36所示，在本实施例中，散热件60还包括第一散热部63，第一散热部63设置于倾斜板62的远离光源20的表面上。第一散热部63设置在倾斜板62上，光源20也设置在倾斜板62上，光源20发出的热量能够传递至倾斜板62上，而第一散热部63能够对倾斜板62进行散热，进而间接地对光源20进行散热。在本实施例中，第一散热部63为间隔设置的多个鳍片，这样能够有效地增加与空气的接触面积，进而有效地实现了散热。
如图27至图36所示，在本实施例中，倾斜板62位于固定板61的中部，散热件60还包括第二散热部64，固定板61包括与倾斜板62成钝角夹角的第一板段611以及与倾斜板62成锐角夹角的第二板段612，第二散热部64设置于第一板段611上，并朝向光源20设置。第二散热部64朝向光源20设置，这样使得第二散热部64能够直接对光源20进行散热。通过第一散热部63和第二散热部64的配合，能够有效地保证光源20的温度，避免其温度过大。具体地，第二散热部64也为间隔设置的多个鳍片，第二散热部64的鳍片的高度小于第一散热部63的鳍片的高度，第二散热部64的鳍片的数量大于第一散热部63的鳍片的数量。
如图27至图36所示，在本实施例中，在本实施例中，散热件60的整体散热面积达到271438mm 2，以便使目前58W的灯珠发热量的整体温度降至100℃以内。
如图27至图36所示，在本实施例中，照明设备还包括连接板，连接板连接于顶板11上，散热件60设置于连接板上，连接板的材质为塑胶。连接板能够有效地固定散热件60，同时连接板能够对散热件60进行散热，进而提高了散热件60的散热效果。并且连接板方便结构设计，该连接板为塑胶件PC材质，结构可塑性较强，方便做固定、防水、防尘等相关设计，且可使外观较为整洁；还便于隔热设计，因该PC材料耐热性100℃较好且导热率较低，所以该连接板在满足耐热的需求下既防止搭接零件受热变形，又可以防止烫伤用户。
如图27至图36所示，在本实施例中，先将光源20安装至散热件60上，再将散热件60安装至连接板上，最后将连接板安装到顶板11上。上述的安装方式是由于围板12是倾斜的，阻碍组装工具螺丝刀等的正常使用，无法直接锁附固定。同时，由于顶板11和围板12围成的腔体的体积较大，需要用高熔值的塑胶材料PC+ABS或ABS以保证材料流动性，以便很好成型，但这种塑胶材料耐热性较差，散热件60直接锁附在腔体容易使其受热变形。
在其他的实施例中，照明设备包括：壳体10、光源20以及出光板30。壳体10上设置有出光口。设置于壳体10内。出光板30设置于出光口处。其中，壳体10包括顶板11以及围板12，围板12的第一端与顶板11连接，出光口设置在围板12的第二端，围板12的中心线与顶板11倾斜设置，光源20设置于顶板11或者围板12上，光源20位于顶板11和围板12的夹角处。通过上述的设置能够有效地提高光源20到出光口之间的光学距离，这样能够在保证整体照明设备的尺寸的前提下，使得照明设备实现自然光的照射效果，同时，将光源20设置在顶板11和围板12的夹角处，这样能够使得照明设备的整体的结构布置更加规整。
光源20的主出光方向与出光口所在平面之间成锐角夹角a。上述的设置能够进一步保证光源20照射的光线的长度。
锐角夹角a在10°至60°之间。上述的角度的设置能够有效地保证光源20与出光口之前的光学距离。具体地在，本实施例中，锐角夹角为45°，倾斜板62与固定板61之间的角度为45°。
顶板11与出光口所在平面平行设置。上述的设置的能够降低加工的难度，并且能够保证照明设备的结构规整。
当然，在其他的实施例中，照明设备，包括，壳体10、光源20以及出光板30。壳体10上设置有出光口。光源20设置于壳体10内。出光板30设置于出光口处。其中，照明设备的底部相对的两个边沿处分别设置有凹台结构和凸台结构。凹台结构和凸台结构能够相互抵接配合，这样能够使得照明设备的拼接更加更加稳定，同时凹台结构和凸台结构的结构简单，加工较为方便。

当然，还可以不设置安装顶板，直接将照明设备安装在房屋的顶壁。
照明设备包括相对设置的两个平行四边形侧板，凹台结构和凸台结构位于平行四边形侧板的侧部。平行四边形侧板的设置能够使得照明设备的竖直截面为平行四边形，这样能在照明设备中形成锐角夹角，这样将光源设置在锐角夹角处，能够有效地增加光线的长度。进而实现自然光的照射效果。
凹台结构压接于凸台结构上。上述的设置能够使得照明设备的拼接更加稳定。
灯具装置还包括支撑块，支撑块安装于其中一个照明设备的边沿上，支撑块设置于最外侧的凹台结构处。支撑块设置在第一个照明设备的凹台结构处，这样使得第一个照明设备能够平稳地连接，同时支撑块的结构简单便于设置。具体地在本实施例中，支撑块通过紧固件固定在凹台结构处。

本实施例的技术方案用于提供在不同场景实现发光面无限拼接的模块化安装技术，以降低的成本、较低的安装场地要求，实现较大发光面的照明需求。同时还可以很好的模拟蓝天效果，实现任意尺寸的模拟天窗需求。同时本实施例的照明设备的外形为平行四边形，这样一方面满足较长光路设计以满足较好光学效果，另一方面有效空间避位实现拼接安装。
如图35所示，连接结构包括相互配合的滑轨和卡扣，滑轨和卡扣中的一个设置于安装顶板上，滑轨和卡扣中的另一个设置于照明设备上，滑轨和卡扣的结构简单，卡扣卡接在滑轨上，这样能够实现照明设备的固定。同时，卡扣能够在滑轨上移动，这样也能够降低装配的难度。具体地在本实施例中，滑轨设置在安装顶板上，卡扣设置在照明设备上。
