This smart desk lamp detects the current light environment and automatically adjusts the light. Annular shadowless lighting minimizes eyes strain. When a child reads a book or writes a homework, the "wisdom bean" on the base of the desk lamp is pinned to the front of the collar. It can automatically sense the child's bad sitting posture and use voice information to remind the child to correct it in time. Through the integration of functions and scenes, children can develop good sitting and eye habits during studying.
