Light reflector and method and device for its manufacture

摘要

The reflector (1) has shell-shaped curved reflector portion (2) having a reflection surface (4) whose inner diameter is increased in a direction of longitudinal central axis between rear lamp opening (8) and front light exit opening (10). The reflection surface is divided into several grid-like facets (12) which are curved in a state extending facet surface (14). The facets are arranged alternately at regular intervals one behind the other within each column group (B) in a state rising and falling repeatedly at specific curvature radii of facets. An independent claim is included for device for manufacturing lamp reflector.
