luminous fluxThe energy field generated by light. See lumen. luminous flux [′lü·mə·nəs ′fləks] (optics) The time rate of flow of radiant energy, evaluated according to its capacity to produce visual sensations; measured in lumens. Luminous flux The time rate of flow of light. It is radiant flux in the form of electromagnetic waves which affects the eye or, more strictly, the time rate of flow of radiant energy evaluated according to its capacity to produce visual sensation. The visible spectrum is ordinarily considered to extend from 380 to 760 nanometers in wavelength; therefore, luminous flux is radiant flux in that region of the electromagnetic spectrum. The unit of measure of luminous flux is the lumen. See Photometry How to thank TFD for its existence?

Ohno, Total luminous flux calibrations of LEDs at NIST, Proc. Avago's ASMC-QHB2-TCD0E (red-orange) and ASMC-QAB2-TAC0E (amber) Envisium LEDs feature typical luminous flux of 6. In order to improve the situation, NIST has investigated the technical problems and is developing standard LEDs and recommended measurement methods for luminous intensity, total luminous flux, and color (chromaticity and dominant wavelength). |
