Abstract
The present invention relates to a reflector cup (10) comprising: a base (12) for a light source (14); a light emission window (16) opposite the base, wherein the light emission window has a larger area than the base; an optical axis (18) extending through the base and the light emission window; and a circumferential reflective side wall (20) extending around the optical axis and connecting the base and the light emission window, wherein one of the light emission window, the light source, and the base has a non-regular shape, and wherein different regions (30a-b; 32a-b) of the reflective side wall at different locations around the optical axis have different curvatures (34; 36) as seen in a plane in which the optical axis extends.
Claims15
A reflector cup comprising:
- a square base for a light source;
- a rounded rectangular light emission window opposite the base, wherein the light emission window has a larger area than the base;
- an optical axis extending through the base and the light emission window;
- and
- a circumferential reflective side wall extending around the optical axis and connecting the base and the light emission window,
- wherein different regions of the reflective side wall at different locations around the optical axis have different curvatures as seen in a plane in which the optical axis extends, and
- wherein the circumferential side wall comprises a first pair of diagonally arranged first corners with a first curvature radius and a second pair of diagonally arranged second corners with a second curvature radius, wherein the first curvature radius is different from the second curvature radius.
