Abstract

SSLSSLSSLSSLSSLSSLSSLSSLSSLSSLA light emitting module (150) emits light through a light exit window (104) and comprises a base (110) a solid state light emitter (154 158) and a partially diffusive reflective layer (102). The base (110) has a light reflective surface (112) which faces towards the light exit window (104). The light reflective surface (112) has a base reflection coefficient Rbase which is defined by a ratio between the amount of light that is reflected by the light reflective surface and the amount of light that impinges on the light reflective surface. The solid state light emitter (154 158) emits light of a first color range (114) comprises a top surface (152 158) and has a solid state light emitter reflection coefficient R_SSL which is defined by a ratio between the amount of light that is reflected by the solid state emitter (154 156) and the amount of light that impinges on the top surface (152 158) of the solid state light emitter (1154 156). A largest linear size dssL of the top surface (106) of the at least one solid state light emitter is defined as the longest distance from a point on the top surface (152 158) of the at least one solid state light emitter to another point on the top surface (152 158) of the at least one solid state light emitter along a straight line. The light exit window (104) comprises at least a part of the partially diffusive reflective layer (102). A solid state light emitter area ratio ? is defined as the ratio between the area of the top surface of the at least one solid state light emitter and the area of the light reflective surface of the base. A gap with a distance h is present between the top surface (152 158) of the at least one solid state light emitter (154 156) and the partially diffusive reflective layer (102). A relatively efficient light emitting module is obtained if 0.3•d = h = 5·d for 0 < ? < 0.1 0.15·d = h = 3·d for 0.1 = ? = 0.25 and 0.1·d = h = 2·d for ? > 0.25 and if the value of the base reflection coefficient Rbase is larger than 70% and larger than the solid state light emitter reflection coefficient R_SSL.
