| luminous | 1. Shining; emitting or reflecting light; brilliant; bright; as, the is a luminous body; a luminous colour. "Fire burneth wood, making it . . . Luminous." (Bacon) "The mountains lift . . . Their lofty and luminous heads." (Longfellow) 2. Illuminated; full of light; bright; as, many candles made the room luminous. "Up the staircase moved a luminous space in the darkness." (Longfellow) 3. Enlightened; intelligent; also, clear; intelligible; as, a luminous mind. " Luminous eloquence." . " A luminous statement." Luminous paint, a paint made up with some phosphorescent substance, as sulphide of calcium, which after exposure to a strong light is luminous in the dark for a time. Synonym: Lucid, clear, shining, perspicuous. Luminously, Luminousness. Origin: L. Luminosus, fr. Lumen light: cf. F. Lumineux. See Luminary, Illuminate. Source: Websters Dictionary (01 Mar 1998) |
| luminous intensity | The luminous flux per unit solid angle in a given direction. Synonym: candle-power, radiant intensity. (05 Mar 2000) |
| luminous retinoscope | <instrument> A portable optical device providing either a circular or linear (streak) beam of light. (05 Mar 2000) |
| bloody flux | The dysentery, a disease in which the flux or discharge from the bowels has a mixture of blood. Source: Websters Dictionary (01 Mar 1998) |
| net flux | The difference between the two unidirectional flux's. (05 Mar 2000) |
| integrated neutron flux | <radiobiology> Sum (integral) of the neutron flux (neutrons per unit time per unit area, see flux) over all time, total number of neutrons which passed through a unit area. Important figure-of-merit in testing effects of neutron radiation on materials, and in assessing how long such materials can survive exposure to neutron sources (such as fission reactor cores and D-T fusion plasmas). (09 Oct 1997) |
| either particle flux density | The particle fluence rate, or energy flux density, the energy fluence rate of intensity. Compare: fluence. (05 Mar 2000) |
| toroidal flux | <radiobiology> Magnetic field flux in the toroidal direction. See: magnetic fields. (09 Oct 1997) |
| unidirectional flux | The flux of a substance from one surface of a boundary layer or membrane to the other, disregarding any counterbalancing flux in the other direction, as measured by tracer technique. (05 Mar 2000) |
| flux | <radiobiology> The total amount of a quantity passing through a given surface per unit time. Typical quantities include (magnetic) field lines, particles, heat, energy, mass of fluid, etc. Common usage in plasma physics is for flux by itself to mean magnetic field flux, unless specified otherwise. (09 Oct 1997) |
| flux density | <radiobiology> Total amount of a quantity passing through a unit surface area in unit time See: flux. (09 Oct 1997) |
| flux, light | <microscopy> Sometimes called luminous flux, the visible portion of the radiant energy emitted by a light source. It is measured in lumens per solid angle. In electrical engineering, it is analogous to the lines of force in a magnetic field, spoken of as magnetic flux. (05 Aug 1998) |
| flux ratio | The ratio of the two unidirectional fluxes through a particular boundary layer or membrane. (05 Mar 2000) |

The flux of visible radiation, so weighted as to account for the manner in which the response of the human eye varies with the wavelength of radiation. The basic unit for luminous flux is the lumen.

| luminous flux |
Defined as the total luminous energy per unit time emitted by the light source into a sphere(360? surrounding the light source, where the luminous flux is the radiant flux multiplied by the human eyes sensitivity. The measurement unit for luminous flux is the lumen (lm).
