Abstract

An intelligent anti-myopia desk lamp that acquires the reading and writing posture of a subject in real time, accurately analyzes the reading and writing posture, and sends an alarm for abnormal states. Including the light source, lamp post and lamp holder, there is an anti-myopia intelligent warning device installed on the lamp post or lamp holder. The input device installed in the identification module of the computer of the device, the storage module that separately or centrally saves the measurement data corresponding to the real-time reading and writing posture of the reader and the standard parameter corresponding to the standard reading and writing posture, and the measurement data exceeds the standard parameter setting range The alarm module and the central processing unit are derived from audio signals corresponding to the real-time posture analysis results of readers. The desk lamp of the present invention can effectively obtain the body posture and posture of the teenagers when reading and writing, and give prompts for incorrect posture or posture. It can accurately measure the distance from the human eye to the book, and has positive significance for the prevention of myopia.
