2.2 Reflectors

Reflector is an optical part that regulates luminous flux from the light source by reflection from reflector material – a mirror reflection, a diffuse reflection, and a mixed reflection.

Reflectors are basically divided into two groups: first group includes conic reflectors of four basic geometries – elliptical, zonal, hyperbolic, and parabolic (Figure 2.2.1); second group includes non-conic reflectors, such as square or asymmetric ones of the same basic geometries of reflection surfaces.
