Abstract

Paraxial imaging equations are derived to determine the image position and magnification of light emitting semiconductor chip of a clear Tl3/4 LED lamp and a positive lens coupling optics. The energy density distribution in the image space of the coupling lens is studied with the help of non-sequential ray trace methodology by generating a computer aided 3D model. Finally the energy density distribution in the image space of the coupling lens is observed experimentally and the results are discussed.
