随着社会的的发展，科技的进步，人们对生活的质量要求越来越高，很多新研发的科技产物也在不断的走进人们的生活当中，身边随处可见的智能设备，让我们的生活变得更加便利且满足。由于现在在电子工程技术的不断发展，人们平日里用来照明的设备也在不断地变化，照明的演变也从明火，到煤油，再到现在的电器，都无一不体现着人类的文明发展。显而易见的是，随着科技的不断进步，也带来了很多负面的问题，能源的减少，环境的污染。这些问题的不断出现，现代科技也不断的在强调节能以及节省资源，所以绿色环保的照明设备越来越多的出现在我们的生活当中，不断地淘汰高能耗照明设备。随着人们生活水平的不断提高，对物质的要求也不断地变高，单一用途的设备在人们的生活越来越少，而人们现在更多地是选着多功能的智能化的照明设备。因此蓝牙智能台灯是现在以及以后生活的必须朋友，在我们日常的生活中会扮演更多地角色。本次设计是利用单片机来改变PWM的占空比来达到调节台灯的灯光，这也是将我们所学到的单片机技术与PWM调光的完美结合的例子。在用台灯时，且在台灯的有效范围内，自动感应开灯，灯光也会跟随者周围的光线而变化，在不需要台灯时，人只要离开台灯的有效范围，在特定的时间后会自动熄灭。通过台灯对光线的感应以及对人体红外的检测来控制对灯光的调节，很好的实现节能减排。为了提高台灯的通途以及使用外围，我们还加入了手动模式，在特殊的环境当中，我们还可以通过手动来控制灯光的开关和强弱。为了更便捷我们还增设了蓝牙工作模块，即我们可以使用手机app来与我们的台灯连接交互，通过手机来对台灯进行监控以和对灯光的调节，以及PWM的调整，让我们的台灯越来越智能。

【Abstract】
With the development of society and the progress of science and technology, peoples quality requirements for life are getting higher and higher. Many newly developed scientific and technological products are also constantly entering peoples lives, and the intelligent equipment that can be seen everywhere makes our lives more convenient and satisfying.
Due to the continuous development of electronic engineering technology, the equipment that people usually use for lighting is also constantly changing. The evolution of lighting also reflects the development of human civilization from open fire to kerosene to electrical appliances. It is obvious that with the continuous progress of science and technology, it also brings many negative problems, energy reduction and environmental pollution. These problems are constantly emerging, and modern technology is also constantly emphasizing energy conservation and resource saving, so green and environmentally friendly lighting is increasingly appearing in our lives, constantly eliminating highenergy lighting. With the continuous improvement of peoples living standards, the material requirements are also constantly increasing, singlepurpose equipment is less and less in peoples lives, and people now choose more multifunctional intelligent lighting. So Bluetooth smart desk lamps are necessary friends in present and future life, and will play a more role in our daily life.
This design is to use a singlechip microcomputer to change the space ratio of PWM to adjust the lamp, which is also an example of the perfect combination of the singlechip microcomputer technology we have learned with PWM dimming.
When using the desk lamp, and within the effective range of the desk lamp, the light will automatically sense the light, and the light will also change according to the light around the lamp. When the desk lamp is not needed, as long as the person leaves the effective range of the desk lamp, it will automatically extinguish after a specific time. Control the regulation of light through the induction of the desk lamp and the detection of human body infrared, which is a good way to achieve energy saving and emission reduction. In order to improve the fluctance of desk lamps and use peripherals, we have also added manual mode. In special environments, we can also manually control the switches and strengths and weaknesses of lights. In order to make it more convenient, we have added a Bluetooth work module, that is, we can use the mobile app to connect to our desk lamps, monitor the desk lamps and adjust the lights through the mobile phone, and adjust the PWM to make our desk lamps more and more intelligent.
