In the afterglow luminescence, the slow component is responsible for the long persistent behavior ; it shows that the initial intensity for this term is [[alpha].sub.L], and the decay rate of the luminous intensity
is proportional to [[tau].sub.L]; that is, larger values for [[alpha].sub.L] and [[tau].sub.L] would result in a higher intensity for (5).
Hence a decrease of more than 30% on luminous intensity
could be expected, as evidenced also in the simulations  executed to define the optical design of the LED-based lamp.
Given only a photometric data report, it is impossible to know how reported zonal lumens of fewer than 10 lumens (and the luminous intensity
values they were based on) were derived from the measured luminous intensity
data (which in turn is inferred from the photosensor illuminance measurements).
The current SI is founded on the seven base quantities, assumed to be independent, time, length, mass, electric current, thermodynamic temperature, amount of substance, and luminous intensity
, for which the SI base units are the second s, meter m, kilogram kg, ampere A, kelvin K, mole mol, and candela cd, respectively; see Table 1.
Illuminance, the amount of light that actually falls on an object, is intimately related to luminous intensity
. Picture that light cone of luminous intensity
; more light per unit area will fall on an object that's close to the luminaire than on an object far away.
These two types of lights differ in luminous intensity
, although the lack of a significant difference does not allow us to conclude that the brightness of the lights has no effect on distance perception.
At night, the entire building lights up like a huge, free-form Japanese paper lantern, glowing with a softly luminous intensity
. Van Velsen's contemporary reinterpretation of a fundamentally introverted building type explores concepts of visual and material lightness, far removed from the historical notion of the cinema as a hulking, opaque bunker.
Candlepower is the luminous intensity
of lamp or luminaire expressed in candles - a standard candle being the unit of luminous intensity
Headliner Juliet Stevenson performed "Footfalls" and "Not I" with luminous intensity
, and the other performers, Debra Gillett and Nigel Cooke, are equally good.
The quality of Mike Nicol's prose, however, gives to the work as a whole a luminous intensity
, a solemnity, that demands a reader's response quite beyond the passive.
In its self-cancelling audacity it manifests, it may be, an exhaustion with style which is itself a new but, in the Eliot oeuvre, a terminal style; and its truest note is that of a melancholy serenity which bids farewell to its symbolist origins and sources, to that poetic of luminous intensity
, pleading a recourse to other personal, familial, national and religious pieties and fidelities.
Simply shifting the curve only changes the angle of the maximum luminous intensity
. The total luminous flux is the same in both cases.
