BROADBAND MIRROR

The invention describes a broadband mirror (1) comprising an outer surface layer (10); and a dielectric layer stack (11A, 11B, 12) arranged underneath the outer surface layer (10); characterized in that the dielectric layer stack (11 A, 11B, 12) comprises at least one patterned surface (110, 120) at an interface between adjacent dielectric layers (11A, 12) of the dielectric layer stack (11A, 11B,12). The invention further describes a light-emitting diode (1). The invention also describes a method of manufacturing a broadband mirror (1), which method comprises the steps of providing an outer surface layer (10) and applying a plurality of dielectric layers (11A, 11B, 12) to build a dielectric layer stack (11A, 11B, 12) underneath the outer surface layer (10), characterized by the step of patterning the surface of at least one dielectric layer (11A, 12) before applying a subsequent dielectric layer (11B, 12) to the patterned surface (110, 120). 本发明描述了种宽带反射镜（1），包括：外表面层（10）；和布置在外表面层（10）下方的电介质层叠层（11A、11B、12）；其特征在于，
