In this work, an empirical model for the emission spectra of LEDs is proposed to describe some crucial optical properties of LEDs. As well known, the junction temperature and the electric driving current are two most important factors of all. According to the phenomenal observation, the empirical model for the emission spectra of LEDs is established to simultaneously include the effects from both the junction temperature and the electric driving current. As a result, the empirical model can be applied for the prediction of the chromatic shifts due to the drift of the operating junction temperature. In addition, the stabilization of the chromatic characteristics is obvious.
