摘要:市场调光台灯多为手动式，即根据使用者的需要，用手转动调光旋钮，改变台灯的亮度，虽然有节约用电的作用，但不是自动调光，更无防近视的功能。目前，学生患近视症的人中很多造成近视的原因，多是在灯下学习或做作业时，由于距光源过近，久而久之，使视力下降，促成近视眼。

　　　我们设计的红外线防近视自动调光台灯是通过监测人与台灯的距离来控制台灯的亮度。人体不能离灯过近，若超过规定(即调定)的距离，灯光便自动变暗乃至熄灭，离开规定距离，灯光则自动变亮从而达到防近视的目的。

　　　我们设计的红外线防近视自动调光台灯由直流电源、红外发射、红外接收、调光五个电路组成。

Abstract:The current household appliances development met a lot of problems. Among them, the control system will industry idea and derivative to life is produce these problems. One of the main reasons Do not only increased the cost and difficulty of intelligent life, also seriously affected the lives of comfort and convenience, and the safety of complex systems, this not reliable to household life destruction is undoubtedly disastrous. So we might as well references for the development of the human process, from the start, rely on cooperation wisdom strengthen ourselves. Use intelligence to improve their lives. So we think household life is the development direction of: a simple and reliable system, application accurate control through high intelligence and synergies, make life easier more comfortable more savings. From a professional standpoint, we are electronic products, gift their soul creator is not only our dreams and our mission. Based on this concept we launched infrared automatic dimmer desk lamp. This lamp glow in the light intensity users the distance from desk lamp close related: the lamp is darker even out; Far as is lamplight to brighten.

　　　It not only can light your bedroom, also can illuminate the way to future family. It is not only consumer goods, but also a member of the family cloud systems. Of course it's a healthy green concept.
