【摘要】 针对目前投影仪在屏幕上投射影像会因为教室光线的影响而显示不清楚的问题,本研究拟设计开发一种新型教室LED自动调光灯,以满足将黑板和幕布光线稳定在合适的光照值内,让黑板和幕布同时看清的要求。论文针对光敏传感器感光装置,单片机控制系统,功率放大装置,LED灯等方面进行了开发设计。最终,通过以上各部分的系统集成来完成整个教室LED自动调光灯研发。更多还原

【Abstract】 The projector’s projected image on the screen can be hard to see because of the impact of light and display clear issues in the classroom, this study was to design and develop a new kind of auto-dimming LED light that dim when the light is too bright in the class-room, so that while the board is over bright from light from the windows it is not overbright from the lights in the classroom. In this paper, a photographic light-sensitive sensor device, a microprocessor control system, a power amplification device, LED lights, and other aspects of the development and design. Eventually, through various parts of the above systems integration to complete the entire auto-dimming LED lights classroom research.更多还原
