Kandela (łac. candela, świeca) – jednostka światłości źródła światła; podstawowa jednostka w układzie SI, oznaczana jako cd [1].
The candela (symbol: cd) is the unit of luminous intensity in the International System of Units (SI). [5] [6] It measures luminous power per unit solid angle emitted by a light source in a particular direction.
Die Candela (lateinisch für ‚Kerze‘, Betonung auf der zweiten Silbe: [1] [kanˈdeːla]) ist die SI-Einheit der Lichtstärke, also des auf den Raumwinkel bezogenen Lichtstroms. Die Lichtstärke ist eine photometrische Größe, die auch die Hellempfindlichkeitskurve des menschlichen Auges einbezieht.
La candela è uno strumento di illuminazione tipicamente costituito da uno stoppino immerso in una colonna di combustibile solido, in genere un qualche tipo di materiale ceroso Storia. Antico fonditore per la produzione di candele in cera d'api. Già gli antichi Romani usavano delle candele rudimentali, costruite ...
A small ornamental candle with a gold stand. A candle is an ignitable wick embedded in wax, or another flammable solid substance such as tallow, that provides light, and in some cases, a fragrance. A candle can also provide heat or a method of keeping time.
The candela per square metre (symbol: cd/m 2) is the unit of luminance in the International System of Units (SI). The unit is based on the candela, the SI unit of luminous intensity, and the square metre, the SI unit of area. The nit (symbol: nt) is a non-SI name also used for this unit (1 nt = 1 cd/m 2). [1]
A candela is the SI base unit of luminous intensity. It measures how bright something is. It is one of the basic units of science. A light bulb is bright, but the Sun is much brighter, so the Sun has more candelas than the light bulb. The frequency chosen for measuring candelas is in the visible spectrum near green.
