摘要
采用红、绿、蓝3条LED发光灯带、3组船型开关以及相对应的亮度调节电位器,自制“三原色光合成”演示教具.该教具不仅可以展示单色光,实现两原色以及三原色等比例的混合,同时还可以实现色光不等比例的混合,从而达到良好的课堂演示效果.
Using red,green and blue LED light strips,three sets of ship-type switches and brightness adjustment potentiometers,the demonstration teaching aid of“tri-color light synthesis”was made.This teaching aid can not only display monochromatic light,realize the mixing of two primary colors or three primary colors in equal proportion,but also realize the mixing of colored light in unequal proportion,so as to achieve good classroom demonstration effect.
