Experimental design of measuring the effect of peak wavelength shift of LED on chrominance

WANG Yuan;PAN Wei;XU Ru-feng;ZHOU Hong;WANG Jin-hui;Department of Physics and Astronomy,Shanghai Jiaotong University;  
LED's lighting was controlled by adjustable constant current source.The LED's spectra were measured by multichannel spectrometer.The peak wavelength shift of colored LED induced by the normal working current was obtained,and the corresponding variation of the chrominance was calculated.
