Abstract
The invention discloses an intelligent light-emitting diode (LED) table lamp. The table lamp comprises an infrared sensor, a 5V rechargeable lithium battery, a single chip microcomputer control chip, a driving circuit and an LED lamp body. The infrared sensor senses strong or weak infrared light from human hands so as to control a single chip microcomputer; the single chip microcomputer controls the LED driving circuit so as to control the brightness of the LED lamp body; an infrared sensor sensing system can cooperate with a timing system so that reading and studying time can be counted, and when the reading and studying time exceeds the time set on a timer, the single chip microcomputer gives alarm and reduces the brightness of the LED lamp body so as to remind a learner of noticing studying time and protecting the eyes; the 5V rechargeable lithium battery can provide power for the LED table lamp during power failure.
Description
Technical field
The present invention relates to a kind of intelligent LED desk lamp.
Background technology
Though current desk lamp used has Single-chip Controlling LED drive circuit to control the brightness of LED, but do not coordinate timekeeping system can calculate the learning time of reading by infrared sensor induction system, the time single-chip microcomputer exceeded on timer will send reports to the police and reduces the brightness of LED, uses not with people institute wish.
Summary of the invention
