| Abstract: | By experiments,the properties of a red LED,a green LED and a blue LED have been studied.The studied properties include stability of emitting light,volt-ampere characteristic and emission light wavelength.For the measurements of light wavelengths of LEDs,two methods,switching voltage method and spectrometer method,have been applied.The measurement results of the two methods show that they are in agreement. |
