WebbThe shape and reflective properties of the modifier allow for great control over the focus and contrast produced by the light — one of the main advantages of these modifiers. I explain and demonstrate all of this in my ‘Understanding parabolic lighting’ live show , where you can see each of these concepts clearly demonstrated. A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves. Its shape is part of a circular paraboloid, that is, the surface generated by a parabola revolving around its axis. The parabolic reflector transforms an … Visa mer Strictly, the three-dimensional shape of the reflector is called a paraboloid. A parabola is the two-dimensional figure. (The distinction is like that between a sphere and a circle.) However, in informal language, the word … Visa mer The principle of parabolic reflectors has been known since classical antiquity, when the mathematician Diocles described them in his book On Burning Mirrors and proved that they focus a parallel beam to a point. Archimedes in the third century BCE studied paraboloids … Visa mer • John D. Kraus • Liquid-mirror telescope, paraboloids produced by rotation • Parabolic antenna Visa mer Focus-balanced reflector It is sometimes useful if the centre of mass of a reflector dish coincides with its focus. This allows it to be easily turned so it can be aimed at a moving source of light, such as the Sun in the sky, while its focus, where the … Visa mer The most common modern applications of the parabolic reflector are in satellite dishes, reflecting telescopes, radio telescopes, parabolic microphones, solar cookers, and many lighting devices such as spotlights, car headlights, PAR lamps and LED housings.
