一种能够实现在两个不同方向投射的双向投影仪。技术方案为:在投影仪的聚光棱镜至投影仪的主镜头的光路之间增设半反射镜,使一部分光线穿过半反射镜保持原来方向,经过主投影镜头投射,另一部分光线被半反射镜反射,呈90°方向经过90°辅投影镜头投射,可以实现在相互垂直的两个方向上投影。如果在90°方向的光路上增设反射镜,使该路光线再折射90°,可以实现在180°方向的双向投影。通过控制按钮控制半反射镜的位置使其离开或进入光路,可以实现单向或双向投影的切换。在双向投影的状态下,通过控制按钮控制反射镜离开或进入光路,可以实现90°双向或180°双向投影的切换。

Bidirectional projector

A bidirectional projector capable of projecting in two different directions. Technical scheme: between the optical path in the main lens projector projector to the condensing prism is added in the half mirror, so that part of the light through the half mirror to maintain the original direction, through the main projection projection lens, the other part of the light being half mirror, a 90 degrees 90 degrees direction through the auxiliary projection lens, can the projection in two directions perpendicular to each other. If a reflector is added to the light path in the direction of 90 DEG, and the light of the road is refracted 90 DEG, a bidirectional projection in the direction of 180 DEG can be realized. Through the control button to control the position of the half mirror to make it leave or enter the light path, the one-way or bidirectional projection can be switched. In the state of bidirectional projection, a switch of 90 DEG or 180 DEG bi directional projection can be realized by controlling the mirror to leave or enter the optical path.
