The bowl-shaped reflector (11) has an inner side (20) having multiple facets (18a,18b,18c), where multiple adjacent facets form a wave. The wave trough and crests are based on the basic form of the reflector. The wave is superimposed on an irregular structure of certain amplitude. Independent claims are also included for the following: (1) a tool for manufacturing a cupped and curved inner side of a reflector; and (2) a method for manufacturing a reflector element. |
