Abstract

该技术属于聚光镜领域，具体涉及一种用于阳极倒置的氙灯的聚光镜。其外壁形状为两条抛物线与一条椭圆曲线的组合；其中椭圆曲线方程为y2＝2R0x-(1-e2)x2，其中R0是曲线顶点曲率半径，e是椭圆离心率，两条抛物线方程为y2＝2px，两条抛物线与椭圆曲线相交，在交点左侧聚光镜的外壁采用抛物线的形状，而交点右侧聚光镜的外壁采用椭圆曲线的形状。在聚光镜的顶部有一圆形孔，用于安装氙灯电极与进行通风散热。本发明在保证聚光镜的聚光效率的条件下，尽量减小聚光镜的尺寸和改善氙灯的散热。

Description

发明内容
本发明的目的在于：提供一种用于阳极倒置的氙灯的聚光镜，提高太阳模拟器的聚光效率。
本发明的技术方案如下：一种用于阳极倒置的氙灯的聚光镜，其外壁形状为两条抛物线与一条椭圆曲线的组合；其中椭圆曲线方程为y2＝2R0x-(1-e2)x2，其中R0是曲线顶点曲率半径，e是椭圆离心率，两条抛物线方程为y2＝2px，两条抛物线与椭圆曲线相交，在交点左侧聚光镜的外壁采用抛物线的形状，而交点右侧聚光镜的外壁采用椭圆曲线的形状。
在聚光镜的顶部有一圆形孔，用于安装氙灯电极与进行通风散热。
本发明的显著效果在于：本发明在保证聚光镜的聚光效率的条件下，尽量减小聚光镜的尺寸和改善氙灯的散热。
附图说明
图1为本发明所述的一种用于阳极倒置的氙灯的聚光镜侧面形状示意图
图2为本发明所述的一种用于阳极倒置的氙灯的聚光镜立体结构示意图
具体实施方式
下面结合附图及具体实施例对本发明作进一步详细说明。
一种用于阳极倒置的氙灯的聚光镜，如图1所示，其形状类似碗状，其外壁形状为两条抛物线与一条椭圆曲线的组合，如图1所示，实线表示椭圆曲线，虚线表示抛物线，其中椭圆曲线方程为y2＝2R0x-(1-e2)x2，其中：R0是曲线顶点曲率半径，e是椭圆离心率，两条抛物线方程为y2＝2px，两条抛物线与椭圆曲线相交，在交点左侧聚光镜的外壁采用抛物线的形状，而交点右侧聚光镜的外壁采用椭圆曲线的形状。如图2所示，在聚光镜的顶部有一圆形孔，用于安装氙灯电极与进行通风散热。
