A conversion element (10) is specified, comprising a scattering layer (12), a reflection layer (14), and a conversion layer (16) arranged between the scattering layer (12) and the reflection layer (14). The scattering layer (12) is designed to transmit a first portion (20) of a primary radiation (18) impinging on it from a side facing away from the conversion layer (16) into the conversion layer (16), and to scatter a second portion (22) of the primary radiation (18) impinging on it towards that side of the scattering layer (12) which faces away from the conversion layer (16). The conversion layer (16) comprises at least one conversion means (25) which is designed to convert at least part of the first portion of the primary radiation (18) into a second radiation (19) having a higher wavelength different from the primary radiation (18). The reflection layer (14) has a reflective effect at least with regard to the second radiation (19). |
