具体实施方式
为了使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和优选实施例对本发明作进一步的详细说明。
支架实施例一
如图1所示，一种LED支架10，包括基板101以及设置在所述基板101上的反射杯102,在所述反射杯102的上表面设置有聚光部件103，所述聚光部件103与反射杯102杯口1021相邻的侧面设有内凹的聚光面1030，在后续LED支架封装完成后，LED芯片射出的部分光线射向聚光面1030并通过聚光面1030反射后与LED芯片射出的其它光线汇聚。
其中，所述反射杯102的材质为工程树脂，可采用聚邻苯二酰胺树脂(PPA)、聚甲基丙烯酸甲脂(PMMA)、聚酰胺(PA)，聚碳酸酯(PC)，聚甲醛(POM)和聚对苯二甲酸丁二醇酯(PBT)中的任意一种，优选白色聚邻苯二酰胺树脂(PPA)。
所述反射杯102的杯口1021可以设置为方形、圆形、椭圆形或者不规则图形，反射杯102的上表面可以是方形，也可以是六边形，附图中显示所述反射杯的上表面呈方形。
所述聚光部件103位于反射杯102上表面的至少一个边上，本实施例中，所述反射杯的上表面为方形，所述聚光部件103位于所述上表面呈方形反射杯的至少一个边上且与所述反射杯102呈一体结构，所述聚光部件103包括第一聚光部件1031和与所述第一聚光部件1031呈一体结构的第二聚光部件1032，其中，所述第一聚光部件1031位于所述反射杯的一个边上，其上表面与所述反射杯的上表面平行，所述第二聚光部件1032位于所述第一聚光部件1031的两侧，是由设置有第一聚光部件的反射杯的一边向相邻两边延伸，并至少覆盖部分所述相邻两边，其表面可以为垂直面、斜面或者曲面，垂直面即与反射杯的上表面垂直，所述第二聚光部件的表面和所述反射杯的上表面所形成的夹角A的范围为90°-120°，当第二聚光部件的表面为曲面时，夹角A为与曲面相切的平面和反射杯的上表面所形成的夹角，本实施例中，所述第二聚光部件的表面为斜面，所述斜面和反射杯的上表面所形成的夹角A的范围为90°＜A≤120°，所述第一聚光部件与第二聚光部件在设置有反射杯杯口的一侧构成了一个内凹的聚光面。
其中附图1中的夹角B即夹角A的补角，根据发明人研究得出，当夹角A的范围为90°-120°时，光线损失率达到最低，可以有效的节约能源，并且观察者可以达到最佳的观察效 果。
所述聚光部件在设置有反射杯杯口的一侧构成的内凹的聚光面1030的形状有很多实施方式，例如，内凹的光滑曲面或平面，在本实施例中，如图1所示，采用内凹的光滑曲面，所述聚光部件与所述支架的上表面可以呈垂直分布，也可以与所述支架的上表面的垂直方向前后偏离一定的角度，通过调整所述聚光部件与所述支架的上表面的垂直方向的角度偏离情况可以调整LED器件的出光角度。
所述LED支架的上表面设置有聚光部件，用于LED器件时，由于所述聚光部件在设置有反射杯杯口的一侧构成的面为内凹的聚光面，此处内凹的聚光面具有聚光作用，LED芯片发出光到达聚光部件的聚光面后被反射回来，然后被聚集在观察者所观察的视野内，有效降低了光在设置有聚光部件的方向上的光线损失，提高了光线利用率。
支架实施例二
如图2所示，本实施例所述的一种LED支架20与实施例一相似，区别在于：在所述聚光部件内凹的聚光面覆盖有反射物质层104，形成反射层，LED芯片发出的光线经聚光部件聚光面的反射物质层104反射，然后被聚集在观察者所观察的视野内，有效提升可视部分的光强，从而能够减少光污染，进一步提高了LED器件的光利用率。
支架实施例三
如图3和图4，本实施例所述的一种LED支架30与实施例一相似，区别在于本实施例对反射杯302的内壁进行了限定。
具体的，所述反射杯302的内壁包括靠近所述聚光部件303的第一内壁3021以及和所述第一内壁3021相对设置的第二内壁3022，所述第一内壁3021与反射杯302杯底3023之间的夹角L1的范围为90°至120°，所述第二内壁3022与反射杯302杯底3023之间的夹角L2的范围为120°至135°，当夹角L1增大时，适当减小夹角L2，可以使光线到达靠近设置有聚光部件303的反射杯302第一内壁3021后被反射回来，然后被聚集在观察者所观察的视野内，可以提高光线的利用率。

本实施例提供了一种基于上述LED器件实施例所述的LED器件制造而成的LED显示模组。
本实施例提供的一种LED显示模组，如图5所示，包括线路基板1，安装在所述线路基板1上的若干个间隔设置的LED器件2，灌封在线路基板上相邻LED器件之间区域的灌封胶体。
所述LED器件用于LED显示模组使用时，可以根据实际需要选择聚光部件的安装方向，将不需要光线的方向上的光反射到能够被有效利用的方向上去，可以使LED显示模组发出的光能够被有效利用。本实施例中，所述LED显示模组安装在室外的高位处，LED器件发出的向上的光不能被有效利用，故本实施例所述聚光部件设置在LED器件的上方，由于所述LED器件的反射杯上表面设置有聚光部件，LED器件发出的向上和部分向左及向右的光，到达聚光部件的聚光面后被反射下来，从而能够被有效利用，降低了光在朝上、部分朝左和朝右方向的光线损失，提高了光的利用率，可以让观察者在观测位置(即LED显示模组的下方)接收到更大强度的光线。
与现有技术相比，本发明的有益效果在于：
1、通过在LED支架的上表面设置有聚光部件，在设置有反射杯杯口的一侧构成了一个内凹的聚光面，此处内凹的聚光面具有聚光作用，LED芯片发出光到达聚光部件的聚光面后被反射回来，然后被聚集在观察者所观察的视野内，有效降低了光在设置有聚光部件的方向上的光线损失，提高了光线利用率。
2、通过在所述聚光部件的聚光面面覆盖有反射物质，形成一层反射层，LED芯片发出的光线经聚光部件聚光面的反射物质反射，然后被聚集在观察者所观察的视野内，有效提升可视部分的光强，从而能够减少光污染，进一步提高了LED器件的光利用率。
3、所述LED器件用于LED显示模组使用时，可以根据实际需要选择聚光部件的安装方向，将不需要光线的方向上的光反射到能够被有效利用的方向上去，可以使LED显示模组发出的光能够被有效利用。
以上对本发明进行了详细介绍，文中应用具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技 术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
