Parabolic reflector. Computer artwork of diverging light beams striking a tilted parabolic reflector from a light source at centre. The rays strike the parabolic mirror and are reflected parallel to each other. This creates a beam of light. This process is used in a number of lighting devices, including spotlights and car headlights.
