摘　　要：基于嵌入式控制技术,提出一种具有区域自识别功能的新型医用观片灯系统结构。该系统以超高亮白光LED构成分布均匀的LED阵列,通过嵌入式控制器识别X光片的规格及覆盖区域,并控制该区域的LED灯阵列发光。本系统所采用的分区LED灯光控制技术不仅可以有效节约电能,大幅延长观片灯寿命,而且还能改善医务工作者观察的舒适度。Based on embedded control technology, this paper proposed a novel system structure of medical view box with region self-identifying function. Super-bright pure-white LED are used to constitute an uniformly distributed LED array. The type and the covering area of the X-ray film are identified and the covered LED are turned on with an embedded controller automatically. Thanks to the region control technology, the proposed system has the merits of better energy saving, longer service life cycle. At the same time, it also makes the observation of X-ray film more convenient.
