摘要
在教育领域,由于国家对现代化教育设施建设力度逐步加强,带动了学校多媒体教室的建设和使用。同时,投影机的使用和维护问题也就日益凸显。无论是哪种品牌和型号的投影机,经过长时间的运行之后,内部产生的热量很大,如果这些热量没有被及时地排出去,投影机的使用寿命会缩短,投影机灯泡的老化速度会加速,最终导致投影机的损坏。本研究就工作中遇到的问题和解决的方案做了详细的描述,供大家参考。
In the field of education, by gradually strengthening national efforts in building modern educational facilities, the construction and application of multimedia classrooms in schools were promoted. At the same time, the problems of projectors＇ application and maintenance had emerged. Whatever the brand and model of the projector, the heat generated inside the machine gets great after a long run. If this heat is not timely discharged, the aging of the projector lamp will be quickened and the projector＇s lifespan will be shortened. In this study, issues encountered in the work and their solutions were described in detail, for reference.
