1. one kind for by preferred blue exciting light that exist with light beam form, high power density (4) with preferably by through light irreflexive, more long wavelength (5) the generation colored light of high brightness or the transmodulator of white light, wherein, described exciting light (4) produces little hot spot on transmodulator, and described transmodulator comprises:

  • -with excitation side with away from the converter bodies (1) of side, excitation side and determined the thickness of converter bodies (1) away from the spacing of side, described thickness was preferred for making through the share of irreflexive exciting light (4) and meticulous coupling of share through irreflexive long wavelength light (5)-wherein, described converter material is the optical ceramics with embedded grain pattern, described optical ceramics is as YAG pottery or LuAG pottery or the magnalium pottery of doping, described grain pattern has strong scattering, to be achieved as follows transmitting spot, described transmitting spot is almost equally large with the beam cross-section of described exciting light (4).
