PURPOSE: A polarization lighting apparatus is provided to improve the performance of a lighting device by changing a color in a decoration. CONSTITUTION: A polarization member(70) is installed in a decoration to transmit light. A polarization light source emits polarized light. A birefringent medium(120) is installed between polarization member and the polarization light source. The light passing through the birefringent medium is emitted to the polarization member installed in the decoration. A displacement member changes a polarization direction of the polarization member.
