Intelligent desk lamp designAbstractWith the changes of The Times and the progress of society ,human beings are constantly pursuing and exploring a more intelligent life.With the requirement of increasing the quality of people's life,also the corresponding with thechanging market,high-tech has become indispensable in people's life also nouns,intelligent technology is applied to electronic products has become the trend of The Times in your life.In real life,intelligent technology has been applied to many electronic products,such as smart washing machine,intelligent electric rice cooker,intelligent induction cooker and so on.In fact,all intelligent electronic products have a common feature,which is to use single chip microcomputer as the central control unit.Combined with the single chip microcomputer intelligent electronic products compared with the ordinary electronic products,on the function,use and safety on hasincomparable advantage,more important is the intelligent electronic products,more energy efficient,corresponding with the quality of the electronic products increases.Intelligent lamp for induction of the body is an infrared signal,on the basis of the pyroelectricinfrared sensor as heat release electrical signal processing circuit,single-chip microcomputer for processing,reach the purpose of easy control of intelligent products.When people are in the dark,thedesk lamp induction to the human body,single-chip microcomputer and a turn on the light's instructions,it will make people leave out the trouble looking for a switch in the dark,and also reduce the unnecessary loss or injury;When people in the learning process,there will always be sitting incorrectly,in the case of too close to the desk,the lamp will give hints,to correct the sitting position,to prevent myopia;Intelligent desk lamp also can autonomously time,when learn a certain time,desk lamp will send out warning,remind people to break time to arrive;When no one is there,the single chip will send out the instruction to turn off the lights to achieve the purpose of energy conservation.Key Words:smart desk lamp;Pyroelectric infrared sensor;Photoelectric switch;-2-
