Claim Text:
1. A light-emitting arrangement, comprising: a reflective member having a reflective surface; a plurality of light-emitting diodes arranged on said reflective surface of said reflective member along a longitudinal direction with respect to said reflective member, said plurality of light-emitting diodes being adapted to emit light of a first wavelength; a wavelength converting member comprising a first wavelength converting material adapted to convert light of said first wavelength into light of a second wavelength, said wavelength converting member being arranged on said reflective member and having a top face oriented parallel to said reflective surface of said reflective member, and having a first side face and a second side face each arranged between said top face and said reflective member on a respective side of said plurality of light-emitting diodes, said first and second side faces extending along said longitudinal direction, wherein light is transmitted through said first side face and said second side face, and wherein said top face is arranged at a vertical distance from a light-emitting surface of said plurality of light-emitting diodes; and a first planar specular reflector and a second planar specular reflector arranged on said reflective member on a respective side of said wavelength converting member, wherein said first planar specular reflector is configured to reflect at least a portion of the light transmitted through said first side face out of said light-emitting arrangement and wherein the at least a portion of the light transmitted through said first side face does not pass through said top face; wherein the top face and at least one of the first or second side face are adapted to convert light of said first wavelength into light of said second wavelength and wherein the reflectivity of said top face is different from the reflectivity of said at least one of the first side face or the second side face; wherein the top face, the first side face and the second side face are adapted to convert light of said first wavelength into light of said second wavelength and wherein the reflectivity of said top face is different from the reflectivity of said first side face and from the reflectivity of said second side face; wherein the reflectivity of said first side face is different from the reflectivity of said second side face.
