Connecting wire between LED light, between LED light and switch 510 is placed in inside the cavity 110.When instructor presses out
After closing 510, the LED light that the corresponding LED light group 500 of the switch 510 is included can be lighted all.
The river as involved in geography course, mountain range are numerous, and in teaching process, instructor is often awarded using language
Class allows student oneself to find a certain mountain range or river in map, many people is caused not catch up with the rhythm of teacher, study is caused to be eaten
Power, and remember and be also easy to appear confusion, meanwhile, in geography class, various lines of demarcation, as monsoon region and non-monsoon region line of demarcation,
Southern and northern line of demarcation, the precipitation such as 800mm, humid region and subhumid boundary etc. are also the emphasis of examination and study, and this
A little lines of demarcation are mostly made of mountain range or river, therefore, are highlighted by way of LED light, efficiency of teaching can be improved,
It can deepen student's impression to a certain extent, improve memory effect, enhance classroom dynamics.
In use process of imparting knowledge to students, instructor's rotary motion handle 330, to drive active roller bearing 300 and driven roller bearing 310
It is rotated.Active roller bearing 300 and driven roller bearing 310 can drive teaching panel 400 to be rotated in rotation, thus when impart knowledge to students
The content of courses on panel 400 generates movement.The content of courses on teaching panel 400, such as the China of Rainfall distribution figure
Map contour is Chong Die up and down with the map of China profile of transparent region A120, stops operating, Rainfall distribution figure can penetrate at this time
Transparent region A120 shows that in face of Faculty and Students, the mode rotated manually can not only reduce cost to a certain extent,
Moreover, reducing the probability of damage, prolong the service life, moreover, the accuracy that manual rotating manner rotates control is higher.Turn
After the completion of dynamic, instructor presses lower switch 510, so that corresponding LED light group 500 lights, facilitates displaying.
