Abstract

There is provided a light emitting module (1) having at least one light emitting element (3) which is arranged to emit light of a primary wavelength and a wavelength converting element (5) arranged at a distance from the at least one light emitting element (3). The wavelength converting element (5) is arranged to convert at least part of the light of a primary wavelength into light of a secondary wavelength. Further the module (1) comprises a first optical component (7) having surface structures (11) on a surface facing away from the light emitting element (3). Light rays incident on the first optical component (7) at small angles are reflected and light rays incident on the first optical component (7) at large angles are transmitted and bent towards a normal of the first optical component (7). The invention is advantageous in that it provides a compact and efficient light directing module.
