摘要
为了让"色光的混合"教学生动形象,让学生对光的合成认识更直观,设计了三原色合成演示仪,该演示仪采用可调直流稳压电源,利用三色光的混合规律,对三原色发光二极管进行了排列设计,同时还将毛玻璃放置在发光二极管的前面,由交叉的光源和毛玻璃共同来完成色光的混合,以增强演示效果.该演示仪可以用来辅助光的合成教学,演示现象明显.
In order to teach vividly and intuitively,a demonstration device for color synthesis with three-primary colors was designed.The device adopted adjustable DC stabilized voltage supply.Basing on the principle of color synthesis,three-primary-color light emitting diodes were arranged.In order to strengthen the demonstration effect,frosted glass was put in front of the light emitting diodes.The device could assist the teaching of color synthesis,and the phenomenon was obvious.
