晶格结构三维模型“LED光立方”的设计与制作

Design and Preparation of LED Light Cubic Model for Showing Three Dimentional Crystal Lattice

针对大学生在学习《固体物理学》等课程中晶格结构理解的困难,采用成熟的LED驱动电路,通过单片机编程技术,利用LED灯设计制作了一套以三维方式表达晶格结构的"LED光立方"模型。模型结合专业特色,凝聚软件和硬件优势,能将复杂的空间结构问题简单化,使学生能直观地认识晶体的立体结构,既能激发学生的课程学习兴趣,同时也为教师提供了多样化的教学手段。

The work aims at the difficulty for undergraduates in understanding the three-dimensional crystal lattice structures in the courses of Solid State Physics and so on. A LED（ Light Emitting Diode）“Light Cube”model was designed and prepared for showing the three-dimensional crystal lattice by using LED driver circuit and microcontroller programming technique. The model combining the features of the related majors and the ad-vantages of the hardware and software can simplify the complex spatial structural problems. It enables students to have an intuitive understanding of the three-dimensional crystal lattice structures. Moreover,it activates their interest in learning the related courses,and also provides the teachers with diversified teaching instruments.
