Description

光源模组以及灯具 技术领域
本发明涉及照明技术领域，尤其涉及一种光源模组以及灯具。
背景技术
透镜是由透明物质(例如玻璃、水晶等)制成的一种光学元件，并基于光的折射原理以应用在照明领域，发光体结合透镜能增强光的使用效率和发光效率，还可以根据不同的效果来使用不同的透镜进而改变发光体的光场分布。通常情况下，透镜单元罩设在发光体上以对发光体进行配光。
目前，照明装置使用时内部会产生热量，透镜单元内的温度会随之升高，使得透镜单元内的压力升高，同时透镜单元由于受热会发生热变形，在高压和高温的共同作用下，透镜单元向背离发光体的方向鼓出，进而导致透镜单元的入光面与发光体的距离增大，此时无疑会改变发光体的出光角度，严重影响到透镜单元的配光效果。由于照明装置内部各区域的温度不同，因此不同区域的透镜单元受到的热变形也不同，在温度较高的区域，透镜单元的热变形更为严重，配光效果更差。
发明内容
本发明公开一种光源模组以及灯具，以解决目前的透镜单元由于受热产生热变形进而影响配光效果的问题。
为了解决上述问题，本发明采用下述技术方案：
第一方面，本发明提出一种光源模组，其包括配光元件和光源板，所述光源板包括电路板和设置于所述电路板上的发光体；所述配光元件上具有多个透镜单元，所述透镜单元均对应罩设在所述发光体上。
所述透镜单元在朝向所述光源板的表面内凹并形成容纳腔，所述容纳腔的表面设置有第一补偿部，所述第一补偿部在朝向所述光源板的表面内凹， 并形成用于容纳所述发光体的配光腔；所述第一补偿部朝向所述发光体的表面为入光面，所述透镜单元背离所述第一补偿部的表面为出光面。
沿靠近所述电路板的几何中心至远离所述电路板的几何中心的方向，所述第一补偿部的厚度依次减小；或者，沿所述电路板的第一区域至所述电路板的第二区域的方向，所述第一补偿部的厚度依次减小，其中，所述电路板的第一区域的所述发光体的密度大于所述电路板的第二区域的所述发光体的密度。
第二方面，本发明提出一种灯具，其包括基部、驱动器件和上述的光源模组，所述配光元件设置于所述基部上并共同向内形成收容腔，所述驱动器件和所述光源板收容于所述收容腔，所述驱动器件与所述光源板电连接。
本发明采用的技术方案能够达到以下有益效果：
在本发明公开的光源模组中，透镜单元内设置有第一补偿部，相较于现有的透镜单元的入光面与发光体的距离，第一补偿部的入光面与发光体的距离更近，当透镜单元受压受热而向外鼓出变形时，第一补偿部的厚度弥补了透镜单元变形而与发光体之间产生的距离，抵消了透镜单元变形对其配光效果的影响，进而能够确保发光体的出射光得到较佳的配光效果；沿靠近电路板的几何中心至远离电路板的几何中心的方向，或者沿电路板上发光体密度较大的区域向发光体密度较小的区域的方向，实质上是沿电路板上温度较大的区域至温度较低的区域的方向，第一补偿部的厚度依次减小，如此第一补偿部的厚度能够与电路板上的不同区域的温度变化对应，进而能够与电路板上不同区域的透镜单元的变形量相匹配，提升了出射光经透镜单元配光后出光角度的准确性。
相较于现有技术中透镜单元由于受热会产生形变，进而会影响到配光效果，该光源模组不仅能够对透镜单元的热变形进行补偿，确保透镜单元保持正常的配光效果，同时第一补偿部的厚度与电路板上不同温度区域的透镜单元的变形量相匹配，确保出射光经透镜单元配光后出光角度较为准确。

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6，本发明实施例公开一种光源模组，其包括配光元件100和光源板200。
光源板200是该光源模组的发光组件，配光元件100为光源板200发出的光线进行配光。通常情况下，该光源模组还包括如后文所述的基部400，基部400则是光源模组的基础构件，为光源模组的其他部分提供安装支撑基础，配光元件100和光源板200就可以设置在基部400上；当然，本发明实施例对此不做具体限制，配光元件100可以直接设置在光源板200上，只需要能够对光源板200发出的光线配光即可。
光源板200包括电路板210和设置于电路板210上的发光体220，发光体220与电路板210电连接以实现发光，配光元件100对发光体220进行配光。在通常情况下，发光体220可以优选为LED发光体，LED发光体具有环保、节能、产热少及寿命长等优点，具体的LED发光体为LED灯珠。当然，本发明实施例对发光体220的具体类型不做限制。
在本发明实施例中，配光元件100上具有多个透镜单元110，透镜单元110均对应罩设在发光体220上。应理解的是，每个透镜单元110均有相对应的一个或者多个发光体220与之配合，发光体220发出的光线经过透镜单元110就实现了配光。
通常情况下，透镜单元110在朝向光源板200的表面内凹并形成容纳腔，发光体220的光线进入到该容纳腔再经过透镜单元110进行配光。在本发明实施例中，该容纳腔的表面设置有第一补偿部300，第一补偿部300在朝向光源板200的表面内凹，并形成用于容纳发光体220的配光腔310。应理解的是，发光体220的光线进入到该配光腔310在经过第一补偿部300和透镜单元110进行配光；同时需要说明的是，本发明实施例不限制发光体220与配光腔310的设置关系，发光体220可以为至少部分位于配光腔310中，也可以全部设置在配光腔310之外，而仅配光腔310与发光体220相对设置，实质上只需要发光体220发出的光线能够进入到配光腔310内即可。
第一补偿部300朝向发光体220的表面为入光面320，透镜单元110背离第一补偿部300的表面为出光面111。具体的，在发光体220的发出的光线进入到配光腔310内后，然后经过入光面320进入到第一补偿部300和透镜单元110内，最后从出光面111射出，如此就完成了配光过程。其中，第一补偿部300和透镜单元110就是配光元件100的光学部分。
通常情况下，透镜单元110的布置方式受到光源模组外观以及内部结构设计的影响，而本发明实施例对透镜单元110的具体布置方式不做限制。发光体220在使用过程中会产生热量，使得电路板210上发光体220所在区域内温度升高，最终会导致透镜单元110的变形。具体的，由于透镜单元110在高温高压下出现热变形并向外鼓出，透镜单元110的入光面与发光体220之间的距离增大，发光体220发出的光线到达透镜单元110的入光面时入射角发生变化，变形后的入射角不符合预设标准，进而会影响到透镜单元110对于发光体220发出的光线的配光效果，最终导致从出光面111出射的光线的出光角度不准确。第一补偿部300处于透镜单元110和发光体220之间，即使透镜单元110发生热变形并向外鼓出，但是第一补偿部300弥补了透镜单元110与发光体220之间增大的距离空间，发光体220发出的光线到达第一补偿部300的入光面320时，变形后的入射角符合预设标准，最终从出光面111出射的光线的出光角度较为准确，进而使得透镜单元110的配光效果不受影响。
其中，由于电路板210的几何中心处于所有发光体220的中心区域，该区域的热量难以流通以实现热交换，相较于电路板210的其他区域，电路板210的几何中心处的温度最高，而向外围温度逐渐降低。在本发明实施例中，沿靠近电路板210的几何中心至远离电路板210的几何中心的方向，第一补偿部300的厚度依次减小。或者，由于光源板200在工作过程中，发光体220的密度大的区域产生的热量多于发光体220的密度小的区域，进而使得电路板210上的区域温度出现高低差异。在本发明实施例中，沿电路板210的第 一区域至电路板210的第二区域的方向，第一补偿部300的厚度依次减小，其中，电路板210的第一区域的发光体220的密度大于电路板210的第二区域的发光体220的密度。综合来看，上述两种第一补偿部300的渐变方式均对应于电路板210上温度较高的区域至温度较低的区域的方向。
应理解的是，如果第一补偿部300的厚度过大，则透镜单元110变形后入光面320离发光体220距离较小，会改变入射光的入射角，从而影响到透镜单元110的配光效果；如果第一补偿部300的厚度过小，则透镜单元110变形后入光面320离发光体220距离较大，依然会改变入射光的入射角，从而影响到透镜单元110的配光效果。因此，当第一补偿部300沿着电路板210上温度较高的区域向温度较低的区域厚度依次减小，能够尽量地确保透镜单元110在变形后入光面320离发光体220的距离较为合适，不改变入射光的入射角，进而实现透镜单元110较佳的配光效果。当然，各个第一补偿部300的厚度需要根据光源模组在实际使用时产生的热量而适应性调整。
由上述内容可知，在本发明实施例公开的光源模组中，透镜单元110内设置有第一补偿部300，相较于现有的透镜单元110的入光面与发光体220的距离，第一补偿部300的入光面320与发光体220的距离更近，当透镜单元110受压受热而向外鼓出变形时，第一补偿部300的厚度弥补了透镜单元110变形而与发光体220之间产生的距离，抵消了透镜单元110变形对其配光效果的影响，进而能够确保发光体220的出射光得到较佳的配光效果；沿靠近光源板200的几何中心至远离光源板200的几何中心的方向，或者沿光源板200上发光体220密度较大的区域向发光体220密度较小的区域的方向，实质上是沿光源板200上温度较大的区域至温度较低的区域的方向，第一补偿部300的厚度依次减小，如此第一补偿部300的厚度能够与光源板200上的不同区域的温度变化对应，进而能够与光源板200上不同区域的透镜单元110的变形量相匹配，提升了出射光经透镜单元110配光后出光角度的准确性。
相较于现有技术中透镜单元由于受热会产生形变，进而会影响到配光效果，该光源模组不仅能够对透镜单元110的热变形进行补偿，确保透镜单元110保持正常的配光效果，同时第一补偿部300的厚度与光源板200上不同温度区域的透镜单元110的变形量相匹配，确保出射光经透镜单元110配光后出光角度较为准确。
在本发明实施例中，入光面320的形状类型可以有多种，例如入光面320可以由多段弧形面平滑衔接而成，本发明实施例对其不做限制。在具体的一种实施方式中，如图5和图6所示，入光面320可以包括在第一补偿部300的长度方向上连接的平面321和弧形面322。
由于不同的入光面320的形状会对入射光的入射角产生不同的影响，而为了保证入射光从不同的入光面320进入到透镜单元110后都得到良好效果的配光，在更为优选的方案中，透镜单元110的第一部分的厚度可以大于第二部分的厚度，其中，第一部分为透镜单元110对应于弧形面322的部分，第二部分为透镜单元110对应于平面321的部分。
当透镜单元110发生热变形并向外鼓出后，发光体220除了与入光面320的距离增大，从另一方面发光体220与配光元件100的表面距离也增大了，在这种情况下，由于发光体220发出的光线是散射状态，发光体220的部分光线就难以进入到配光腔310，而直接入射在配光元件100的表面，使得这部分光线不能被配光并从出光面111出射，最终减弱了光源模组的照度。基于此，在较为优选的方案中，第一补偿部300的边缘外侧可以沿周向设置有第二补偿部700，第二补偿部700呈环状。具体的，由于第二补偿部700呈环状，其内部具有通孔，发光体220发出的光线可以通过该通孔进入到配光腔310内；与此同时，即使在透镜单元110发生热变形并向外鼓出的情况下，第二补偿部700弥补了配光元件100的表面与发光体220之间增加的距离的空间，发光体220散射出的光线被第二补偿部700所阻挡并产生反射，进而使得这些原本入射到配光元件100的表面的光线被反射到配光腔310内，最 终实现配光而确保了光源模组具备正常的照度。
如果第二补偿部700厚度过大，则增加了制造成本且会与电路板210产生干涉；如果第二补偿部700厚度过小，则难以起到对发光体220的散射光线进行反射的作用，因此在更为优选的方案中，可以沿靠近电路板210的几何中心至远离电路板210的几何中心的方向，第二补偿部700的厚度依次减小；或者，可以沿电路板210的第一区域向电路板210的第二区域的方向，第二补偿部700的厚度依次减小，其中，电路板210的第一区域的发光体220的密度大于电路板210的第二区域的发光体220的密度。应理解的是，上述两种第二补偿部700的渐变方式均对应于电路板210上温度较高的区域至温度较低的区域的方向，具体的，在温度较高的区域，配光元件100的表面与发光体220的距离增大较多，则第二补偿部700的厚度设置较大，在温度较低的区域，配光元件100的表面与发光体220的距离增大较少，则第二补偿部700的厚度设置较小。当然，各个第二补偿部700的厚度需要根据光源模组在实际使用时产生的热量而适应性调整。
为了提升第一补偿部300和第二补偿部700与配光元件100的连接稳定性，在较为优选的方案中，第一补偿部300和第二补偿部700中至少有一者可以与配光元件100一体成型。应理解的是，可以仅第一补偿部300和第二补偿部700的其中一者与配光元件100一体成型，也可以第一补偿部300和第二补偿部700均与配光元件100一体成型；一体成型的连接方式可以使得第一补偿部300和第二补偿部700与配光元件100之间没有间隙，使得配光效果更佳，而且也能够避免光线从第二补偿部700与配光元件100之间射出。
当然，本发明实施例不限制第一补偿部300和第二补偿部700与配光元件100之间的具体连接关系，例如第一补偿部300和第二补偿部700与配光元件100之间还可以通过粘接、卡接等实现连接。
在本发明实施例中，配光元件100的类型可以有多种，可以优选为平面透镜。
请再次参考图1，基于上述的光源模组，本发明实施例还公开一种灯具，其包括基部400、驱动器件500和上述的光源模组。基部400是灯具的基础构件，为灯具的其他部分提供安装支撑基础，驱动器件500和该光源模组都设置在基部400上。
配光元件100设置于基部400上并共同向内形成收容腔410，驱动器件500和光源板200收容于收容腔410。为了便于分类以及避免出现干涉，在较为优选的方案中，收容腔410可以包括第一子腔411和第二子腔412，光源板200收容于第一子腔411，驱动器件500收容于第二子腔412。当然，本发明实施例对收容腔410的具体设置布局不做限制。
在本发明实施例中，配光元件100与基部400的连接关系可以有多种，例如卡接、粘接等，在具体的一种实施方式中，配光元件100通过紧固件固定在基部400上。紧固件可以优选为螺纹紧固件，例如螺钉、螺栓等，使得二者的拆装较为方便。
驱动器件500与光源板200电连接，具体的，驱动器件500用于对光源板200的控制，二者之间可以通过电连接件实现电连接，电连接件可以优选为柔性线缆、FPC等。
为了提升灯具整体的密封性，在较为优选的方案中，灯具还可以包括密封件600，基部400的边缘设置有限位凹陷420，密封件600被配光元件100压紧密封装配于限位凹陷420。具体的，密封件600提升的是基部400与配光元件100之间的密封性。通常情况下，限位凹陷420为凹槽，当然限位凹陷420还可以为其他类型，例如卡槽等。本发明实施例不限制密封件600的具体类型，密封件600可以优选为橡胶密封圈、密封泡棉等。
通常情况下，基部400上可以设置有灯座430，进而方便灯具的安装。
为了进一步地防止透镜单元110的热变形，在较为优选的方案中，基部400可以为散热罩。具体的，在实际使用过程中，基部400可以散失掉灯具内部的部分热量，避免灯具内部温度过高，间接地提升灯具整体的防热变形 能力。为了实现更好地散热，基部400通常为散热性能良好的金属结构件，例如铁质件、铝质件等。当然，金属结构件的强度较大，有利于基部400为灯具的其它部件提供较好的支撑。
本发明实施例所公开的灯具可以是路灯、台灯、厂房吊灯等，本发明实施例不限制照明灯具的具体类型。
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。
