luminous flux
Usage examples
  • When the reflex reflector is illuminated by CIE standard illuminant A, with an angle of divergence of 20' and an illumination angle V = H = 0 C, or, if this produces a colourless surface reflection, an angle V = ± 5 C, H = 0 C, the trichromatic coordinates of the reflected luminous flux must be within the following limits ...

light flux variant
  • Rahvusvahelise suuruste süsteemi ISQ tuletatud suurus
  • suurus, mis väljendab valguse võimsust nägemisaistingu järgi
  • ISQ derived quantity
  • measure of the perceived power of light
valgusvoog
Usage examples
  • Valgusvoog arvestab silma tundlikkust, kaaludes võimsust igal lainepikkusel heledusfunktsiooniga, mis esindab silma reaktsiooni erinevatele lainepikkustele.
luminous flux preferred
Usage examples
  • The luminous flux accounts for the sensitivity of the eye by weighting the power at each wavelength with the luminosity function, which represents the eye's response to different wavelengths.
