Using high brightness LED to design the practical teaching aid and demonstrating the mixture of colored light

The physics curriculum, "a mixture of colored light", is a fundamental science education and also related knowledge of life. Students are always confusing for the superimposition of colored light and mix of color pigments, which conceptions were based on the experiences of life. In this research, demonstrating the mixture of colored light is based on the novel and intuitive device, a simple and practical experimental device is designed by the light emitting diode (LED) light source with three primary colored light. Teacher can utilize the results of variation of mixture of colored light, which is demonstrated by the novel device for mixture of colored light, to present the superimposition of three primary colored light and the relationships between color and light. Using such high-brightness LED light mixing aids to demonstrate the results of the color variations, will enhance students' attention and interest in learning. Teachers will provide more practical optical experience of color mixing for students.
