The excerpt below from a Wiki page describes applications of parabolic mirrors.
Parabolic Mirror Applications
A parabolic mirror (or reflector) is a reflective device used to project and collect energy like light and sound. Parabolic mirrors can either be on-axis or off-axis. When they are on-axis, parabolic mirrors produce collimated reflected light. Off-axis parabolic mirrors focus reflected light to a focal point off-axis.How parabolic mirrors are used to extend the intensity of car headlights:
Energy radiating from the focus to the mirror can be transmitted outward in a beam that is parallel to the axis of the mirror. Which if we are talking about Car headlights will intensify the light and make the light beam glare in no particular direction.
How parabolic mirrors are used to reduce lightpollution in big cities:
Parabolic Mirrors reduce light pollution in big cities because it uses a reflective to collect energy, like light. So any incoming ray that is parallel to the axis of the dish will be collected to a central focus. Many types of energy can be reflected this way, parabolic reflectors can be used to collect and concentrate energy entering the reflector at a certain angle.
