English translation isn't very good. The photos are not in the Lightroom program. The photos are stored in folders on your computer. Lightroom just opens a catalog which is a database that keeps track of where your photos are stored. IF you deleted your photos then they are gone. You cannot import photos to Lightroom and then delete them. I apologize if I have misunderstood your question.
If I am reading right, you deleted your images. You're seeing image previews in Lightroom and this is "fooling" you - there are ways to get images from these previews but they will be inferior: Script to extract previews of lost or deleted photos
