Abstract

A light emitting arrangement (100) comprises: a reflective member (101) having a reflective surface (102); at least one light emitting diode (103) arranged on the reflective surface of the reflective member the at least one light emitting diode being adapted to emit light of a first wavelength; and a wave length converting member (104) comprising a first wavelength converting material adapted to convert light of the first wavelength into light of a second wavelength. The wavelength converting member is arranged on the reflective member and having a top face (105)oriented parallel to the reflective surface of the reflective member and having a first side face (106) and a second side face (107)each arranged between the top face and the reflective member on a respective side of the at least one light emitting diode and wherein the top face is arranged at a vertical distance (V1) from a light emitting surface (108) of the at least one light emitting diode. By adapting the properties dimensions and/or orientation of the faces of the wavelength converting member according to the invention a desirable light distribution from the light emitting arrangement is achieved.
