Abstract
This utility model relates to a projection device, including a light source assembly for generating a light source; a dimming assembly including a light guide and an image generation unit, wherein the image generation unit and the light guide are disposed on the light path of the light source assembly, and the image generation unit is configured to receive electrical signals and output corresponding optical images; a lens assembly disposed on the light path of the light source assembly and located behind the dimming assembly, the lens assembly being used to magnify the image generated by the image generation unit and project it onto a target surface; and a light shield having a light-transmitting hole, through which the image generated by the image generation unit passes and projects an image with fading edges onto the target surface. This utility model aims to solve the problem that existing simple projection devices cannot achieve a fading edge effect.
