método para prover um revestimento refletor a um substrato para um dispositivo emissor de luz, substrato adaptado para ser provido com um dispositivo emissor de luz e dispositivo de emissão de luz

摘要

The present invention relates to a method for providing a reflective coating (114) to a substrate (104) for a light-emitting device (112), comprising the steps of: providing (201) a substrate (104) having a first surface portion (116) with a first surface material and a second surface portion(106, 108) with a second surface material different from the first surface material; applying (202) a reflective compound (401) configured to attach to said first surface material to form a bond with the substrate (104) in the first surface portion (116) that is stronger than a bond between the reflective compound (401) and the substrate (104) in the second surface portion (106, 108); curing (203) said reflective compound (401) to form a reflective coating (114) having said bond between the reflective coating (114) and the substrate (104) in the first surface portion (116); and subjecting said substrate (104) to a mechanical treatment with such an intensity as to remove (205) said reflective coating (114) from said second surface portion (106, 108) while said reflective coating (114) remains on said first surface portion (116).
