More Information
Summary:The utility model provides a low-glare projection device, comprising a DLP light machine used for projecting an image light beam; the wedge-shaped lens is provided with an acute angle, and the wedge-shaped lens is used for deflecting the direction of the image light beam; and the diffusion sheet is used for receiving the deflected image light beam, enabling all the image light beam to be focused on the diffusion sheet to display an image and generating image light, and the image light is scattered and transmitted forwards. 本实用新型提供一种低眩光的投影装置，包括：DLP光机，用于投射一影像光束；楔形透镜，具有一锐角，楔形透镜用以偏折影像光束的方向；扩散片，用于接受偏折的影像光束，并让影像光束全部聚焦在扩散片以显示一影像，并产生一影像光，该影光向前散射传递。
