具体实施方式
下面结合附图和具体实施例对本发明作进一步详细的说明， 并不是把本发明的实施范 围局限于此。
如图 1至图 4所示， 本实施例所述的一种曲率可变的照明透镜装置， 包括灯体 1、 散热 块 2、光源 3和反射罩 4， 所述光源 3为 LED光源， 该光源 3以散热块 2进行散热， 以确保 LED光源工作正常，光源 3发出的光通过反射罩 4进行反射，在灯体 1内安装有平板透镜 5， 该曲率可变的照明透镜装置还包括软体硅胶 6、 软体硅胶盒 7、 可变透镜罩 8、 透镜调节装 置 9和透镜调节旋钮 11， 软体硅胶盒 7和平板透镜 5紧密相连， 软体硅胶 6灌注在软体硅 胶盒 7中， 可变透镜罩 8的下端部抵压在软体硅胶 6上端面， 可变透镜罩 8为一中空体， 内部形成空腔， 外侧设有环形凸台； 当软体硅胶 6受到可变透镜罩 8的压力时， 软体硅胶 6 产生形变； 由于软体硅胶 6两侧受力， 那么软体硅胶 6向中间挤压， 并向上隆起， 从而进 入可变透镜罩 8内部空腔中； 透镜调节装置 9通过螺杆和可变透镜罩 8连接， 透镜调节旋 钮 11和透镜调节装置 9装配在一起， 透镜调节装置 9和灯体 1装配在一起。 所述软体硅胶 6受力作用能产生形变。 所述软体硅胶 6是透明的。 所述软体硅胶盒 7是透光的。 所述透镜 调节装置 9与可变透镜罩 8通过螺杆相连。 该曲率可变的照明透镜装置还包括透镜 10， 所 述透镜 10和透镜调节旋钮 11连接在一起。 为了保持软体硅胶 6的透光度， 增加了透镜 10， 使得外部空气与可变曲率的软体硅胶 6隔离， 从而保证软体硅胶 6具有稳定的透光率。 所 述可变透镜罩 8下端的端口呈圆形， 从而使得软体硅胶 6变形后能够改变出光角度。 本实 施例在制造过程中， 先将高透明度的硅胶化合物灌注在可以透光的软体硅胶盒 7 中， 待硅 胶固化后， 形成受力后可以产生弹性变形的软体硅胶 6， 可变透镜罩 8紧紧压在软体硅胶 6 上， 当透镜调节旋钮 11旋转时， 带动透镜调节装置 9上下移动， 从而带动可变透镜罩 8上 下移动， 使得软体硅胶 6在软体硅胶盒 7中发生变形， 该变形通过可变透镜罩 8改变成曲 率可变的圆形透镜， 从而实现灯具出光光线方向的改变， 进而改变了灯具光线的投射角， 圆形透镜曲率改变的大小与可变透镜罩 8 的上下移动位置有关， 移动位置越大， 圆形透镜 曲率越大， 从而使得光线的投射角度越大， 最终实现了通过设在灯具外部的透镜调节旋钮 11， 改变了灯具的投射角的功能。 可变透镜罩 8紧紧压在透明的软体硅胶 6上， 透镜调节 装置 9与可变透镜罩 8利用螺杆相连， 当透镜调节旋钮 11旋转时， 根据螺杆传动原理， 当 旋动透镜调节旋钮 11， 透镜调节旋钮 11驱动透镜调节装置 9， 透镜调节装置 9通过螺杆驱 动可变透镜罩 8， 可变透镜罩 8的下端紧紧压住软体硅胶 6， 使软体硅胶 6按照可变透镜罩 8的形状而改变形状， 从而实现灯具透镜曲率的改变。 图 1是本实施例在软体硅胶未变形时 的纵向剖视图， 在该状态下， 透镜曲率为零， 软体硅胶 6保持平整， 其作用相当于一个普 通的平板玻璃。 图 2是本实施例在软体硅胶小变形时的纵向剖视图， 在该状态下， 透镜曲 率较小， 软体硅胶 6 形成了一个曲率不为零的凸透镜， 从而改变了光线的投射角及出光方 向， 灯具实现了光线投射角的改变。 图 3是本实施例在软体硅胶 6大变形时的纵向剖视图， 在该状态下， 透镜曲率较大， 光线的投射角较大， 灯具照射范围较大。 图 4是本实施例中 的可变透镜罩 8的纵向剖视图， 软体硅胶 6按照可变透镜罩 8的形状而改变形状， 从而实 现灯具透镜曲率的改变。 图 5为本实施例的使用状态图， 它是一 LED轨道重点照明灯具， 包括灯体 1， 灯具连杆 12以及专用的灯具电器盒 13， 灯具电器盒 13通过灯具连杆 12连接 灯体 1， 其结构还请参见图 3， 所述光源 3为 LED光源， 该光源 3以散热块 2进行散热， 以 确保 LED光源工作正常，光源 3发出的光通过反射罩 4进行反射，把 LED光源发出的光都 集中在透镜上， 以确保整个灯具的光效率，平板透镜 5与软体硅胶盒 7紧密相连，确保 LED 光源 3的光通过透明的软体硅胶 6。在本实施例中所述的方向以图 3为准， 图 3的上方为上 端， 图 3的下方为下端。
以上所述仅是本发明的一个较佳实施例， 故凡依本发明专利申请范围所述的构造、 特 征及原理所做的等效变化或修饰， 均包含在本发明专利申请的保护范围内。 工业应用性 本发明创造包括灯体、 软体硅胶、 软体硅胶盒、 可变透镜罩、 透镜调节装置和透镜调 节旋钮， 在灯体内安装有平板透镜， 软体硅胶盒和平板透镜紧密相连， 软体硅胶灌注在软 体硅胶盒中， 可变透镜罩的下端部抵压在软体硅胶上端面， 透镜调节装置通过螺杆和可变 透镜罩连接， 透镜调节旋钮和透镜调节装置装配在一起， 透镜调节装置和灯体装配在一起。 在 LED照明灯具中采用本发明后， 其光线投射角度可以调节， 光线投射角度调节方便、 可 靠， 同一个灯具能够满足不同重点照明场所的要求， 并能满足用户改变 LED照明灯具出光 角度的要求， 本发明创造可以批量生产， 具有良好的市场前景。
