Definition of candela in English:

candela

(also cd)

noun kanˈdɛləˈkandɪlə

Physics

The SI unit of luminous intensity. One candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 10¹² Hz and that has a radiant intensity in that direction of 1/683 watt per steradian.
〔物理〕坎德拉，新烛光（发光强度单位）
Example sentencesExamples
- SI (Système Internationale d' Unites) uses seven different fundamental units, the meter, kilogram, second, ampere, kelvin, candela, and mole.
- We have a 15-inch demo and a 50-inch demo, and have achieved 600 candelas per square meter generating 1 millimetre sized pixels.
- According to the spec sheet, the FP231W is supposed to deliver about 250 candelas / square-meter of brightness.
- Nits are also a measure of luminance, in so many candela per square metre.
- These types of detectors should be calibrated in lumens/amps, which allows easy calculation of candela values.

Origin

1950s: from Latin, 'candle'.
