Description

LED射灯
本发明涉及一种LED照明灯具，特别是一种LED射灯。
LED光源具有发光效率高、低发热、省电和寿命长的优点，因此其应用越来越广泛。LED灯将逐渐取代白炽灯和卤素灯等传统照明灯具。采用LED光源进行聚光、泛光照明时，一般采用反光杯或透镜对LED光源进行配光。但是，传统的反光杯或透镜仅仅使用简单的锥形反射面，它们虽然能实现聚光功能，但是，由于配光形状存在缺陷，这些结构难以实现高效的定向配光。
有鉴于此，有必要提供一种能实现高效定向配光的LED射灯。
本发明采用的技术方案为：一种LED射灯，包括透镜、LED光源板及一颗或多颗呈点光源状排列的LED光源，该透镜设置在该LED光源板的上方，该透镜为顶部较大而底部较小的倒台体结构，该透镜的底部大致正对该LED光源设有入射面，该透镜的顶部形成大致平行该LED光源板的出射面，该透镜的侧面形成反射面，该入射面为朝向远离该LED光源凹陷的凹槽结构，该入射面包括第一入射部、第二入射部及设置在该第一入射部与该第二入射部之间的过渡段，该第一入射部设置在该入射面的中部并正对该LED光源发出的大致平行其中轴线方向的光线设置，该第一入射部大致平行该LED光源板设置以将该LED光源发出的光线朝向该出射面折射，该第二入射部设置在该第一入射部的外围，该过渡段为弧形结构，该过渡段用于将该LED光源发出的靠近其中轴线方向的光线朝向该反射面折射，该第二入射部大致垂直该LED光源板设置以将该LED光源发出的偏离其中心轴的光线朝向该反射面折射，该反射面用于将射来的光线朝向该出射面折射。
发明的有益与现有技术相比，LED射灯通过设置入射面、出射面、反射面形成配光结构，LED光源发出的光一部分穿过入射面后直接朝向出射面照射出去，另一部分光穿过入射面后经过反射面的反射最终朝向出射面照射出去。而其中入射面包括第一入射部、第二入射部及过渡段。第一入射部设置在该入射面的中部且大致平行于该LED光源板设置，并对LED光源发出的光配光后使得光线大致平行于该透镜的中轴线。第二入射部设置在该第一入射部的外围且大致垂直该LED光源板设置，并对LED光源发出的光配光将光线朝向反射面折射，再通过反射面将光线朝向出光面照射出去。过渡段连接第一入射部与第二入射部且为弧形结构，用于将光线朝向该反射面折射，在通过反射面将光线朝向出光面照射出去。因此使得光线通过第一入射部、第二入射部及过渡段的作用可实现25°-120°范围内光束角的调整。同时通过绝大多数的光线都能够通过第二入射部及过渡段的折射使得光线朝向反射面照射，在再通过反射面的反射向外照射出去。从而使得该LED射灯具有能实现高效定向配光的优点。

是图1所示LED射灯中透镜的主视图。
是沿图2中A-A线的剖视图。
下面结合附图与具体实施方式对本发明作进一步详细描述。
本发明第一实施例的LED射灯100，请参考图1至图3。
请参考图1至图3，一种LED射灯100，包括透镜20、LED光源板10及一颗或多颗呈点光源状排列的LED光源12，该透镜20设置在该LED光源板10的上方，该透镜20为顶部较大而底部较小的倒台体结构。该透镜20的底部大致正对该LED光源12设有入射面21，该透镜20的顶部形成大致平行该LED光源板10的出射面23，该透镜20的侧面形成反射面22，该入射面21为朝向远离该LED光源12凹陷的凹槽结构。其中，该反射面22为锥形的弧面结构。该入射面21为以该LED光源12的中轴线为中心轴旋转而成的回转体结构。
由上述结构LED射灯100通过设置入射面21、出射面23、反射面22形成配光结构，LED光源12发出的光一部分穿过入射面21后直接朝向出射面23照射出去，另一部分光穿过入射面21后经过反射面22的反射最终朝向出射面23照射出去。其中，该入射面21为朝向远离该LED光源12凹陷的凹槽结构，仿制卤素灯外形，满足市场多样需求。入射面21为以中轴线为中心轴旋转而成的回转体结构，使得绝大多数光线11均能够从该入射面21进入且四周具有较为均匀的配光。该反射面22为锥形的弧面结构，使得绝大多数的光线11能够通过该反射面22进行反射后向外照射出去。
该透镜20靠近该LED光源板10设置，使得该入射面21覆盖该LED光源12设置。该透镜20的底面紧贴该LED光源板10设置，使得该LED光源12产生的热量经过该LED光源板10传至该透镜20，同时，该入射面21覆盖该LED光源12设置。该透镜20由玻璃或塑料或陶瓷一体制成。
请参考图1至图3，该入射面21包括第一入射部211、第二入射部212及设置在该第一入射部211与该第二入射部212之间的过渡段213，该第一入射部211设置在该入射面21的中部并正对该LED光源12发出的大致平行其中轴线方向的光线11设置，该第一入射部211大致平行该LED光源板10设置以将该LED光源12发出的光线11朝向该出射面23折射，该第二入射部212设置在该第一入射部211的外围，该过渡段213为弧形结构，该过渡段213用于将该LED光源12发出的靠近其中轴线方向的光线11朝向该反射面22折射，该第二入射部212大致垂直该LED光源板10设置以将该LED光源12发出的偏离其中心轴的光线11朝向该反射面22折射，该反射面22用于将射来的光线11朝向该出射面23反射。
由上述结构，入射面21包括第一入射部211、第二入射部212及过渡段213。第一入射部211设置在该入射面21的中部且大致平行于该LED光源板10设置，并对LED光源12发出的光配光后使得光线11大致平行于该透镜20的中轴线。第二入射部212设置在该第一入射部211的外围且大致垂直该LED光源板10设置，并对LED光源12发出的光配光将光线11朝向反射面22折射，再通过反射面22将光线11朝向出光面照射出去。过渡段213连接第一入射部211与第二入射部212且为弧形结构，用于将光线11朝向该反射面22折射，在通过反射面22将光线11朝向出光面照射出去。因此使得光线11通过第一入射部211、第二入射部212及过渡段213的作用可实现25°-120°范围内光束角的调整。第一入射部211为曲率很大的球面或者为平行于LED光源板10，因此第一入射部211能够对朝向其照射的光线11朝向透镜20的中轴线聚光，使得光线11在小角度具有光线11照射。同时通过将第二入射部212设置为大致垂直该LED光源板10，因此使得入射面21被拉高，使得绝大多数的光线11都能够通过第二入射部212及过渡段213的折射使得光线11朝向反射面22照射，在再通过反射面22的反射向外照射出去。一方面，大大提高了光学效率，降低照明光斑使得照明效果更好。另一方面，使得绝大多数的光线11通过配光实现聚光或朝向大角度照射，实现光束角的调整。
请参考图3，还包括台阶段214，该台阶段214的一端连接该第一入射部211，该台阶段214的另一端连接该过渡段213，该台阶段214的设置使得该第一入射部211相对该LED光源板10的高度大于该过渡段213及该第二入射部212相对该光源板的高度。该台阶段214大致垂直该LED光源板10设置。
综上所述，第一入射部211设置在该入射面21的中部且第一入射部211为曲率很大的球面或者为平行于LED光源板10，因此第一入射部211能够对朝向其照射的光线11朝向透镜20的中轴线聚光，使得光线11在该中轴线附近的小角度能实现较好的聚光。同时通过将第二入射部212设置为大致垂直该LED光源板10，因此使得入射面21被拉高，使得绝大多数的光线11都能够通过第二入射部212及过渡段213的折射使得光线11朝向反射面22照射，在再通过反射面22的反射向外照射出去。这样，一方面，大大提高了光学效率，降低照明光斑使得照明效果更好。另一方面，使得绝大多数的光线11通过配光实现聚光或朝向大角度照射，实现25°-120°范围内光束角的调整。这就使得该透镜20整体的高度可以做得比较低。该台阶段214的设置使得使得部分从LED光源12上发出的偏离其中轴线的光线被该台阶段214朝向该出射面23折射，相比不设置该台阶段214的情形，这种折射后的光线更加偏向于偏向该中轴线的方向。所以，设置该台阶段有利于使光线朝向平行于中轴线的方向发射，有利于聚光。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明保护的范围之内。
