Description

配光元件及灯具 技术领域
本发明涉及照明技术领域，尤其涉及一种配光元件及灯具。
背景技术
LED玉米灯是常用的一种灯具，其形状及灯珠分布如同玉米棒，并可沿周向360°发光，故被称为LED玉米灯。现有的LED玉米灯通常包括有安装筒以及沿安装筒周向侧壁布设的LED灯珠，由于LED灯珠射出的大部分光线都集中于安装筒侧壁的法向上，使得LED玉米灯的光线发散度不足，而导致其上存在暗区或阴影，并且该问题在LED玉米灯的端部尤为凸显。
发明内容
本发明公开一种配光元件及灯具，以解决目前的灯具存在暗区的问题。
为了解决上述问题，本发明采用下述技术方案：
第一方面，本发明提供一种配光元件，适用于为光源进行配光，其包括至少两个沿其高度方向排布的第一配光模组，所述第一配光模组沿周向环绕于所述光源，所述第一配光模组包括相互背离的入光面和出光面，所述入光面与所述光源相对设置，所述第一配光模组自所述入光面至所述出光面为发散光线构型；相邻两个所述第一配光模组之间具有凹陷区。
第二方面，本发明提供一种灯具，其包括光源组件以及前述的配光元件，所述光源组件包括至少两个沿所述灯具的高度方向排布的第一光源模组，所述配光元件包括至少两个沿所述灯具的高度方向排布的第一配光模组，一个所述第一配光模组罩设于一个所述第一光源模组，且所述第一配光模组沿所述灯具的周向罩设于所述第一光源模组。
本发明采用的技术方案能够达到以下有益效果：
在本发明公开的配光元件中，其包括至少两个沿其高度方向排布的第一配光模组，且第一配光模组沿周向环绕于光源设置，如此即可实现灯具周向360°的配光；同时，基于第一配光模组的发散光线构型，使得光源发出的光线通过第一配光模组后散射，在第一配光模组的出光方向上实现了更大的照射覆盖面，因此光线的光路可更贴近配光元件的表面。
相较于现有技术，本发明公开的配光元件应用于灯具时，灯具具有更大范围的照射覆盖面，不仅提升了灯具的能耗利用率，同时光源发出的光线经配光元件发散之后，使得光线的光路更贴近灯具表面，进而能够有效消除灯具上的暗区，而且，由于第一配光模组沿灯具的高度方向排布、并可对灯具周向360°进行配光，因此该配光元件无疑能够对灯具进行全表面无死角地暗区消除。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
以下结合附图，详细说明本发明各个实施例公开的技术方案。
请参考图1～图4，本发明实施例公开一种配光元件300，其适用于为光源结构进行配光。在本实施例中，所公开的配光元件300包括至少两个沿其高度方向排布的第一配光模组310，也即是说，第一配光模组310的数量可以为两个，也可以大于两个；当然，本实施例未限制第一配光模组310的具体数量。在实际应用时，该配光元件300与光源结构相对设置，光源结构发出的光线投射至配光元件300上，配光元件300即可对这些光线进行配光。
具体地，第一配光模组310沿周向环绕于光源，如此设置下，每个第一配光模组310均可以实现对光源结构周向360°的配光。第一配光模组310包括相互背离的入光面和出光面，入光面与光源相对设置，在具体的配光过程中，光源结构发出的光线首先投射至入光面，而经第一配光模组310配光处理后再由出光面出射。
需要说明的是，目前光源结构发出的光线通常均为散射光，即光线相互之间不平行，而是会存在一定的角度差异，这些光线中角度差异最大的两条 光线的角度差为最大角度差。在现有技术中，灯具通常包括灯罩，当光源结构发出的光线通过灯罩后，光线的最大角度差不会变化，由于光线多集中于光源结构本身的法向上，而灯罩表面大部分区域缺少光线照射，进而导致灯罩的表面存在较多的暗区和阴影。
在本实施例中，第一配光模组310自入光面至出光面为发散光线构型。应理解的是，如图4所示，在具体的工作过程中，当光源结构发出的光线投射至入光面，光线进入到第一配光模组310中进行配光，光线从出光面出射后，光线都会被再次散射，使得光线整体变得更为发散，具体表现为出射光的最大角度差明显大于入射光的最大角度差。
当出射光的最大角度差变大之后，部分光线与配光元件300表面之间的夹角变小，即更贴近于配光元件300表面，因此在配光元件300的表面会有更多的光线照射，进而能够消除配光元件300表面的暗区和阴影。结合前述，由于第一配光模组310沿周向环绕于光源设置，因此每个第一配光模组310均可在配光元件300的周向上对暗区和阴影进行消除，也即第一配光模组310能够对配光元件300表面进行360°的暗区消除；同时，多个第一配光模组310沿配光元件300的高度方向排布，如此在全部的第一配光模组310的共同作用下，即可对配光元件300进行全表面无死角的暗区消除。
需要说明的是，灯具的表面即为配光元件300的表面，因此本实施所公开的配光元件300应用于灯具时，即能实现灯具的全表面无死角的暗区消除。
通常情况下，相邻两个第一配光模组310之间具有凹陷区340，凹陷区340通常为相邻两个第一配光模组310之间的间隔区域，也即由于配光元件300上由于第一配光模组310的密度通常不足以完全覆盖配光元件300表面而存在的间隔空间，当然凹陷区340还可以为基于第一配光模组310的结构构型而形成凹陷结构。在现有技术中，上述的凹陷区340由于缺乏光线的照射，极容易形成大块的暗区或阴影。在本实施例中，经第一配光模组310配光之后的光线，特别是由第一配光模组310的边缘出射的光线，即可投射至 凹陷区340内，而消除掉暗区。
本实施例所公开的配光元件300可直接作为灯罩使用，不仅能够为光源结构进行配光，还能够对光源结构起到一定的防护作用；当然，配光元件300也可作为灯罩的部分而设置。
由上述说明可知，在本发明公开的配光元件300中，其包括至少两个沿其高度方向排布的第一配光模组310，且第一配光模组310沿周向环绕于光源设置，如此即可实现灯具周向360°的配光；同时，基于第一配光模组310的发散光线构型，使得光源结构发出的光线通过第一配光模组310后散射，在第一配光模组310的出光方向上实现了更大的照射覆盖面，因此光线的光路可更贴近配光元件的表面。
相较于现有技术，本发明公开的配光元件300应用于灯具时，灯具具有更大范围的照射覆盖面，不仅提升了灯具的能耗利用率；同时光源结构发出的光线经配光元件发散之后，使得光线的光路更贴近灯具表面，进而能够有效消除灯具上的暗区，而且，由于第一配光模组310沿灯具的高度方向排布、并可对灯具周向360°进行配光，因此该配光元件300无疑能够对灯具进行全表面无死角地暗区消除。在实现暗区消除的基础上，用户即可获得更佳的照明体验感。
在本实施例中，第一配光模组310的具体类型可以有多种，例如第一配光模组310为一个整体的环状配光结构，其入光面和出光面均为一个。在另一种具体的实施方式中，第一配光模组310可以包括多个沿周向围绕布设于光源的配光单元330，配光单元330均包括相互背离的入光面单元331和出光面单元332；在一个所述第一配光模组中，所述入光面单元331沿周向彼此相连而形成所述入光面。
应理解的是，在现有技术中，配光单元330通常间隔布设，灯具上能够布设的光源结构有限，因此灯具整体的光线强度也存在上限；其次，由于光源结构发出的光线通常集中其自身法向上的正前方，当光线再被配光单元 330散射之后，光线的出射角度会变大，进而导致光线整体的强度降低，使得光效变差。
而在本实施方式中，由于不同的配光单元330的入光面单元331都彼此相连，因此在一个第一配光模组310中，配光单元330之间不再像现有技术一样被隔断，也即，配光单元330之间不存在隔断结构，因此在相同的安装空间中，第一配光模组310内能够安装容纳更多的光源结构，如此便能够发出更多的光线，由于入光面单元331形成了统一的入光面，因此这些光线都能够自第一配光模组310的入光面、并再由出光面出射。从该配光元件300应用到灯具整体来看，光源结构增多，无疑能够提升灯具的照明亮度，进而使得光效更佳。
同时，由于在灯具的周向上光源结构增多，因此也能够缩小相邻光源结构在配光元件300的出光面上产生的暗区的大小，无疑有利于减少灯具表面的暗区。
通常情况下，在第一配光模组310中，配光单元330的出光面单元332可以彼此相连。如此设置下，在灯具的周向上配光单元330之间不存在间隔区域，也即，在灯具的周向上的配光元件300均会有光线通过，如此无疑能够避免在灯具的周向上产生暗区。当然，本实施例未限制第一配光模组310中的出光面单元332的具体配合关系，在可选的实施方式中，可以仅部分配光单元330的出光面单元332彼此相连，与可以配光单元330的出光面单元332均间隔设置。
如前所述，经过配光散射后的出射光会进入凹陷区340中，进而起到消除暗区的作用。在本实施例中，在该配光元件300上，可设置凹陷区340专门用于供光源发出的光线进行散射。
应理解的是，出射光在投射至凹陷区340后会继续传播至相邻的第一配光模组310的表面，在此种情况下，通过凹陷区340投射至相邻的第一配光模组表面的光线会再次被反射，并改变光路而与其他的光线汇聚、并提升灯 具整体的光线强度和光效。
如前所述，在本实施例中，凹陷区340的具体形式有多种。举例来说，当配光元件300的表面上第一配光模组310间隔设置时，凹陷区340即为相邻两个第一配光模组310之间的间隔区域。在另一种具体的实施方式中，如图3和图4所示，在配光元件300的高度方向上，相邻的两个配光单元330可以彼此相连、并在二者之间形成有凹陷部341；在配光元件300的周向上，多个凹陷部341组成凹陷区340。
具体而言，如此设置下，在配光元件300的周向上，多个凹陷部341能够形成凹陷区340，进而确保能够具有前述凹陷区340的有益效果；同时，相邻的两个第一配光模组310此时为邻近设置，使得凹陷区340所在的配光元件300表面不再存在无光线通过的区域，如此无疑能够避免在灯具的高度方向上产生暗区；再者，如此设置下，可使得配光元件300上的结构设计更为紧凑，在同样的表面积下，能够在配光元件300上设置更多的第一配光模组310，进而能够适配更多的光源结构，而进一步地提升灯具整体的光线强度和光效。
在本实施例中，未限制配光单元330的具体类型，配光单元330通常可选用为透镜结构，例如菲涅尔透镜；当然配光元件300也可以为其他的配光结构，例如平面反射镜、反射棱镜等反射结构，具体而言，反射结构可在配光元件300表面对光线进行反射，以改变光线的光路并反射至凹陷区340等配光元件300表面上可能存在暗区的区域。请参考图1～图7，基于前述的配光元件，本发明实施例还公开一种灯具，所公开的灯具包括光源组件200以及前述的配光元件300。其中，光源组件200为灯具的发光构件，在本实施例中，配光元件300罩设在光源组件200的外部，即配光元件300为光源组件200发出的光线进行配光。
具体地，光源组件200包括至少两个沿灯具的高度方向排布的第一光源模组210，配光元件300包括至少两个沿灯具的高度方向排布的第一配光模 组310，一个第一配光模组310罩设于一个第一光源模组210，且第一配光模组310沿灯具的周向罩设于第一光源模组210。应理解的是，第一光源模组210和第一配光模组310的数量可以为两个，也可以大于两个；当然，本实施例未限制第一光源模组210的具体数量。在实际应用时，一个第一配光模组310对应罩设在一个第一光源模组210上，第一光源模组210发出的光线投射至第一配光模组310上，第一配光模组310即可对这些光线进行配光。
如图1和图2所示，结合前述配光元件300在其高度方向上设置第一配光模组310，同时第一光源模组210也沿灯具的高度方向上排布，此种布设方式较为简单，第一配光模组310的形状较为规则，降低了配光元件300及灯具整体的布设和加工难度。
需要说明的是，在配光元件300的生产加工过程中通过模压成型，配光元件300通常包括第一子部和第二子部，两个子部分别模压成型后再组合在一起而形成配光元件300；通常情况下，第一子部和第二子部通过设置能够相互配合的定位结构来实现组配。在具体的灯具装配过程中，通过将第一子部和第二子部套接在组配好的光源组件200的外部，再组配好配光元件300即可；在拆卸灯具时，将第一子部和第二子部分离，即可将光源组件200从配光元件300中取出，也可以对光源组件200进行检修。
在本实施例中，未限制配光元件300的形状轮廓。如图1和图2所示，配光元件300可以为正六棱柱形；如图5所示，配光元件300可以为正四棱柱形；如图6所示，配光元件300可以为正三棱柱形；如图7所示，配光元件300可以为长方体形。
光源组件200包括有发光体230。通常情况下，发光体230可选为LED发光体，LED发光体具备环保、节能、使用寿命长等；当然，本实施例不限制发光体230的具体类型。具体地，第一光源模组210包括多个沿其周向排布的发光体230，第一配光模组310的配光单元330对应罩设于第一光源模组210的发光体230。在实际应用时，第一光源模组210的发光体230发出 的光线可投射至第一配光模组310的配光单元330上，配光单元330即可对这些光线进行配光。
在本实施例中，配光单元330与发光体230的配光关系可以有多种，通常情况下，一个配光单元330对应对一个发光体230进行配光；而如图2所示，一个配光单元330可对两个发光体230进行配光；本实施例未限制配光单元330与发光体230的具体配光关系。当然，一个发光体230也可以由多个配光单元330进行配光。
光源组件200通常包括有基板240，发光体230设置于基板240上，进而能够被基板240供电。本实施例未限制基板240的具体类型，其可以为套设在安装基部100上的柔性电路板，也可以为分块均匀布设的刚性电路板，刚性电路板可直接插接固定于后文所述的灯座500中。通常情况下，灯具还可以包括灯座500，配光元件300具有收容腔和开口，开口与收容腔连通，配光元件300在开口一侧设置有配合部350，配光元件300通过所述配合部350与灯座500可拆卸连接，光源组件200设置于收容腔内。具体而言，基于灯座500与配光元件300的可拆卸连接，可实现对收容腔的外露与封闭，以便于装拆光源组件200，如此也提升了灯具整体的装拆便捷性。
需要说明的是，本实施例未限制灯座500与配光元件300之间的具体配合关系，通常配合部350可以为卡扣结构，基于配合部350，配光元件300可以与灯座500实现卡接配合；当然，基于配合部350结构变形，配光元件300与灯座500还可以通过诸如粘接、螺纹连接等方式来实现可拆卸连接。
通常情况下，灯具还可以包括设置于收容腔内的安装基部100，安装基部100可为灯具的基础构件，并为灯具的其他组成部分提供安装基础。当然，在本实施例中，灯具也可以不包括安装基部100，光源组件200可通过依附设置于配光元件300、灯座500等。
在本实施例中，第一光源模组210设置于安装基部100的外周面，为了与前述内容相适配，第一光源模组210沿安装基部100的高度方向排布，第 一配光模组310沿安装基部100的高度方向排布。安装基部100通常可呈柱状，如此方便在其上设置光源组件200；当然，安装基部100一般基于灯具的形状轮廓而匹配形状，例如在灯具为球形灯时，安装基部100也可以设置为球状。为了提升灯具的散热性能，在可选的方案中，光源组件200可以设置于安装基部100的部分外周面，且安装基部100为热良导体件。具体而言，光源组件200只是覆盖了安装基部100的部分外周面，而未被光源组件200覆盖的另一部分外周面则直接外露于空气中；由于安装基部100是热良导体件，其能够快速吸收部分光源组件200的热量(主要直接来自于基板240)，起到均匀分布热量的作用，避免光源组件200在使用过程中温度太高而被损坏。
同时，安装基部100上的热量会在未被光源组件200覆盖的外周面与空气进行热交换，将部分热量散失到空气中，从而能够再次吸收光源组件200的热量，以对光源组件200进一步降温。
当然，本实施例未限制安装基部100的具体材料类型，安装基部100可以由银、铝等导热性较好的金属材料制成。举例来说，安装基部100可以为由铝板组合的结构件。
在安装基部100呈柱状的实施方式中，为了进一步地提升灯具整体的照射覆盖面，在可选的方案中，光源组件200还可以包括第二光源模组220，灯座500设置于安装基部100的第一端一侧，第二光源模组220位于收容腔内、且设置于安装基部100的第二端；配光元件300可以包括第二配光模组320，第二配光模组320对应罩设于第二光源模组220。
应理解的是，如此设置能够弥补灯具在安装基部100的第二端一侧的照明缺失，第一光源模组210和第二光源模组220配合使用，就能够实现灯具更大范围的照明区域。特别是在室内顶部照明的应用场景中，本实施方式能够确保灯具底部的区域能够获得充足有效的照明效果。
进一步地，第二配光模组320的配光单元330也可以为发散构型，使得 第二光源模组220的发光体230发出光线在出射之后，最大角度差变大，进而使得光线更贴近在安装基部100的第二端一侧的配光元件300的表面，以进一步消除配光元件300表面的暗区或阴影。
由于光源组件200在使用时需要供电，因此灯具还包括驱动组件400，驱动组件400设置于安装基部100或灯座500，光源组件200与驱动组件400电连接。在使用时，可以通过控制驱动组件400来调整光源组件200的开关。
在本实施例中，未限制驱动组件400的具体类型，举例来说，驱动组件400可以为蓄电池。在一种具体的实施方式中，驱动组件400可以包括电控板410和电连接部420，安装基部100具有内腔，内腔在第一端与外部连通，电控板410至少部分设置于内腔中，也就是说，电控板410可以部分设置于内腔中、而部分设置于灯座500，或者全部设置于内腔中。光源组件200与电控板410电连接，电连接部420与电控板410电连接，在具体使用时，电连接部420与电源连接实现对电控板410和光源组件200的供电，电控板410可以实现对光源组件200的开关、强度或颜色等的调整。
在本实施例中，电连接部420可以设置于灯座500上，电连接部420可以为开设于灯座500上的电连接端口，也可以为穿设于灯座500并伸出至配光元件300之外的电插针。当然，本实施例不限制电连接部420的具体类型。
通常情况下，电连接部420为多个电插针，而为了便于设置电插针以及提升电插针的连接稳定性，在可选的方案中，电控板410包括转接面411，转接面411设置于安装基部100的第一端，多个电插针均可一端安装于转接面411上、另一端穿设于灯座500而伸出至灯具之外，以便通过电插针与外部电源电连接而实现对灯具的供电。
本发明上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域 技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
