The light source (1) is based on a high-efficiency solid-state laser source (2) of the excitation coherent radiation (3) and a single crystal phosphor (4) which is machined in a form of an optic element for emitted light parameterisation. The single crystal phosphor (4) is produced from a single crystal material on the basis of garnets of the (Ax, Lu1-x)aAlbO12:Cec general formula or from a single crystal material on the basis of perovskite structure of the B1-qAIO3:Dq general formula. The efficient light source (1) shall be utilized e.g. in the automotive industry.
