Abstract
A reflector of a lighting apparatus such as a flashlight has a cupped body with a first pair of opposing walls and a second pair of opposing walls extending from an aperture at the cupped body center to a rectangular opening. The internal surfaces of the walls are reflective. Each of the first pair of walls is concavely curved with a focus point in front of a filament light source inside the cupped body and each of the second pair of walls is convexly curved with a focus point exterior to the cupped body. The first pair of opposing walls and the second pair of opposing walls are shaped to reflect light from the filament light source through the rectangular opening to form a predetermined flood beam by breaking up the filament image and reflecting the resulting light.
