Description

一种双曲面透镜及LED灯具
本申请要求了申请日为2020年12月28日，申请号为202023223756.2，实用新型名称为“一种双曲面透镜及LED灯具”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及照明灯具领域，具体涉及一种双曲面透镜及LED灯具。
背景技术
LED灯具有寿命长、光效高、低功耗、节能、环保等突出特点，因此正被应用到越来越多的技术领域。其中，玉米灯和球泡灯灯体小巧、安装方便、款式新颖，在装饰大灯以及各种装饰灯罩中使用非常广泛。玉米灯和球泡灯在横向方向为360度发光，但由于LED光源是朗伯发光体，其发光角度是120度，导致玉米灯在纵向方向发光角度仅有120度，造成了使用玉米灯或球泡灯的装饰灯罩在纵向方向亮度分布不均的现象。由于装饰灯罩中底部连接器部件等外结构限制以及玉米灯的外尺寸限制，使得玉米灯的照射范围有局限性，不能照亮灯罩的上、下两侧，产生被照面中间局部过亮，上、下方照度偏暗的问题。
为解决上述问题，技术人员将透镜应用至玉米灯以实现大角度发光。在对现有技术的研究和实践过程中，本申请的发明人发现，现有的透镜设计虽能扩大玉米灯的发光角度，但其结构复杂、透镜加工难度大；另一方面，通过平贴透镜的全反射方式增加下出光比例会导致下出光占比较少且会损失较多光能，照明效果不佳。

如图5所示，设定一直线，该直线与所述中心轴线平行且通过所述LED光源202的中心，该直线与所述第一曲面具有第一交点2021和第二交点2022，所述第一交点2021到所述LED光源202的中心的距离为a1，所述第二交点2022到所述LED光源202的中心的距离为a2；该直线与所述第二曲面1022具有第三交点2023和第四交点2024，所述第三交点2023与所述第一交点2021在所述LED光源202的同一侧，所述第四交点2024与所述第二交点2022在所述LED光源202的同一侧，所述第三交点2023与所述第一交点2021的距离为b1，所述第四交点2024与所述第二交点2022的距离为b2；其中，a1＝a2，b1＝b2；或者a1≠a2，b1≠b2；或者a1＝a2，b1≠b2；或者a1≠a2，b1＝b2。
当a1＝a2，b1＝b2，且所述双曲面透镜100为对称结构时，所述LED光源202的中心位于所述双曲面透镜100的对称面上。当a1≠a2，b1≠b2；或a1≠a2，b1＝b2，且所述双曲面透镜100为对称结构时，所述LED光源202的中心不在所述双曲面透镜100的对称面上。当所述双曲面透镜100为对称结构时，上述结构可保证所述LED光源202发射出的光线在各个方向上均能被反射并保证光照范围。
当a1＝a2，b1≠b2；或者a1≠a2，b1＝b2时，所述双曲面透镜100为非对称结构。当所述双曲面透镜100为非对称结构时，为了保证所述LED灯具200具有最大面积的光照范围，需将所述双曲面透镜100的中心与所述LED光源202的几何中心设置在同一水平面上，以使得所述LED光源202发射出的光线经过不对称的所述双曲面透镜100时在各个方向上均能够被折射。
当所述LED灯具竖直设置时，所述第三交点2023在所述第四交点2024的上方，所述b1＞a1，b2＞a2。将所述第一曲面1021至所述第二曲面1022的距离设置得稍大一些有利于在所述LED光源202发出光线后，所述双曲面透镜100能够在最大范围内对最多的光线进行折射，更大的曲面厚度可以增大光线的折射角度，使得所述LED灯具200获得更大的照明范围，实现蝙蝠翼配光。且不同距离的的设置方便根据实际需要设置不同配光角度的双曲面透镜，达到不同照明效果。
如图6所示，所述LED灯具200还包括电连接端子203、电极2031、灯罩204、灯座205。
所述电连接端子203上具有相应的电极2031，所述PCB基板201固定在所述电连接端子203上且与所述相应的电极2031连接。所述电连接端子203为所述LED灯具200提供了线路连接及供电设备，使得所述LED灯具200可持续发光，实现照明效果。
所述电连接端子203包括插接式连接端子、螺纹式连接端子中的一种。根据实际需要设置不同种类的电连接端子，方便所述LED灯具200在不同场景下的安装及使用。
所述LED光源202发出的光线，经过所述双曲面透镜100射出后，所述光线的反向延长线与所述中心轴线的夹角为15°～90°。所述双曲面透镜100与所述LED光源202的组 合设置可实现大角度全方位的照明效果，使得经所述双曲面透镜100射出的光线可到达各个方向上，为所述LED灯具200提供最大的光照面和最佳的照明效果。
所述双曲面透镜100、所述PCB基板201、所述LED光源202以及所述电连接端子203安装至所述灯罩204内；所述灯座205固定安装至所述电连接端子203下方。所述灯罩204与所述灯座205的设置方便所述LED灯具200在实际应用中的使用、固定与美观。
所述垂直于所述中心轴线1011方向的平面为所述双曲面透镜的对称面。可选的，所述双曲面透镜的对称面可与该平面设置一定的垂直距离，方便根据所述LED光源202在所述灯罩中的相对位置设置所述双曲面透镜100的配光角度大小，所述LED光源202在所述灯罩204中相对于上下边缘的距离不同，可分别对所述第一曲面1021和所述第二曲面1022的透镜面型进行设计，使所述LED光源202发出的光线能够均匀照亮所述灯罩整体，以使得所述灯罩在其上、下边缘处获得更佳的照射效果。
