Let the desk lamp move with you - a perceptive desk lamp

If I didn't say that, you must think it's just an ordinary desk lamp. Unfortunately, it's not. This desk lamp can perceive your reading posture within a certain range through setting, and keep the distance between the light and the book, so that it won't hurt your eyes because of the dark light in a certain extent. This desk lamp is so interesting, no matter how you move the book with your hands. The desk lamp will automatically adjust the distance between your book and the light.
