Luminous energy

The radiant energy in the visible region or quantity of light. It is in the form of electromagnetic waves, and since the visible region is commonly taken as extending 380–760 nanometers in wavelength, the luminous energy is contained within that region. It is equal to the time integral of the production of the luminous flux. See Photometry

Luminous Energy

 

radiant energy that can be detected by the human eye or by other optical detectors whose spectral sensitivity is equal to that of the average eye. The term “luminous energy” is also used in the sense of quantity of light. In this sense it is equal to the product of the luminous flux and the time in which the flux is radiated or received. The unit of luminous energy is the lumen-second.

luminous energy

[′lü·mə·nəs ′en·ər·jē]
(optics)
The total radiant energy emitted by a source, evaluated according to its capacity to produce visual sensation; measured in lumen-hours or lumen-seconds.

luminous energy

The time integral of luminous flux; given by the product of the luminous flux and the time that the flux is maintained, if the luminous flux is of constant value; usually expressed in lumen-hours.
