【Abstract】 The authors designed a demonstration of chromaticity experiment based on novel tricolor LEDs.An adjustable power supply was made for the tricolor LEDs,which were environment-protected and power-saving.The experiment demonstrated additive and subtractive color mixing,and fluorescence excited by the blue LED.The optical experiments were simple, and the experimental phenomena were clear.更多还原
