Modeling and Fitting of Asymmetrical Spectrum of Blue Light-Emitting Diode
The asymmetricalspectrum from the bluelight-emitting diode (LED) was experimentally measured,mathematically modeled,empirically approximated,numerically simulated and fitted,and compared with the spectra simulated and fitted with Gaussian and Lorenz models,widely used to approximate and simulate the emission spectrum emitted of a monochromatic LED.The newly-formulated mathematical model gives full consideration to the physical mechanism responsible for blue light emission.The measured spectrum,emitted from a blue LED,was simulated with the new model and software packages MATLAB and ORIGIN.The simulated results show that when it comes to fitting precision of the asymmetricalspectrum emitted from a blue LED,the newly-formulated model outperforms both Gaussian and Lorenz models.
