Spherical Mirrors ‒ Reflector

Reflector is the part of the headlamp, which provides a concentration of light in a desired direction. It has a concave mirror, placed behind the light source, which is reflecting back the light beams propagating in other than the desired direction. When necessary to achieve a parallel beam, the mirror is in a shape of the parabola, with the light source positioned at its focal point. The light source is a bulb connected to a power source through a switch which is turning the flashlight on and off. The light beams are emitted in all directions from the filament. A radiated beam falls on the reflective layer and due to the law of reflection is reflected parallel with other reflected rays and forming a parallel beam. Rays that do not reflect and go straight through the protective glass are forming a luminous flux in a shape of a cone. Rays reflected from the reflective layer create a cylinder of high luminous flux. Thanks to the combination of the different shape, different position of the lamps and the lampshades, every car can be fitted with a low beam lights, high beam lights and the daytime running lights.
