1. A semiconductor light emitting element comprising:

  • a light emitting layer for emitting primary light having a first wavelength;

    a wavelength converter located in the light extraction side of said light emitting layer to absorb said primary light emitted from said light emitting layer and to emit secondary light having a second wavelength different from said first wavelength; and

    a first optical reflector located in the light extraction side of said wavelength converter, and having a low reflectance to said secondary light emitted from said wavelength converter and a high reflectance to said primary light emitted from said light emitting layer.
