Large-polarization large-space illumination optical device

The invention relates to a large-polarization large-space illumination optical device which is characterized in that a right enhanced refraction light-emitting surface with a zigzag section is additionally arranged on the outer surface of a right reflection part, so that light which is incident from a refraction light-incident curved surface and is propagated rightwards is deflected leftwards through the right enhanced refraction light-emitting surface; on the basis of reflection, the polarization angle is further enhanced, and the utilization efficiency of light is improved. The LED lamp is suitable for large-space lighting places such as tunnels, roads and lighting requirements in targeted directions, and is easy and convenient to install. 本发明涉及一种大偏光大空间照明光学装置，该装置通过在右反射部的外表面增加截面为锯齿形的右加强折射出光面，使得由折射入光曲面入射的向右传播的光线经右加强折射出光面向左偏折出射，在反射基础上进一步加强了偏光角度，提高了光线的利用效率。本发明适用于隧道、道路以及有针对性方向照明需求等大空间照明场所，安装简单便捷。
