The physical-mathematical model of LEDs in the plastic case. As the parameters of the model used by the geometric dimensions of crystal and shell elements, refractive index and absorption coefficient of the shell and crystal. In addressing the problem of propagation of radiation taken into account the processes of reflection from the base of the shell, cylindrical and spherical surfaces of the dome, the effects of refraction of rays on these surfaces, the absorption of radiation in the crystal and the material of the shell. Adequacy of the model is tested by comparing the calculated and experimental directivity pattern of radiation. The theoretical and experimental results of patterns of light-emitting diodes investigations are presented. The directional characteristics of the pattern versus the case parameters are analyzed.
