We investigated the laser‐phosphor light source by using inorganic phosphor wheel. We experimentally confirmed the light extraction efficiency of the inorganic phosphor wheel which is 8% higher than conventional phosphor wheel. In addition, we explain about the cause of improvement of the efficiency by showing fluorescence emission model.
