luminous intensity

In 1851, the luminous intensity of the lantern was further increased.

Luminous intensity is the perceived power per unit solid angle.

Prior to 1948, various standards for luminous intensity were in use in a number of countries.

There was a silence; Brendel's eyes burned now with a luminous intensity.

ED marks the points in a digital image at which the luminous intensity changes sharply.

The luminous intensity would still be one candela in those directions that are not obscured.

The luminous intensity of a typical candle is thus approximately one candela.

Such a source could then be used to calibrate instruments designed to measure luminous intensity.

A common candle emits light with roughly 1 cd luminous intensity.

A typical candle produces light with about 1 candela of luminous intensity.

However, low luminous intensity of the emitting surface is useful because it reduces glare.

However, it is still sometimes used to describe the luminous intensity of high powered flashlights and spotlights.

The luminous intensity for light of a particular wavelength λ is given by

In either case, luminous intensity is tabulated from this data and used in lighting design.

The unit of luminous intensity, candela, is realized by using an absolute radiometer.

Light with the same radiant intensity at other wavelengths has a lower luminous intensity.

Luminance for instance is a measure of the density of luminous intensity in a given direction.

A lamp can produce higher luminous intensity either by producing more light, or by focusing it tighter.

A unit for measuring luminous intensity.

The luminous intensity was 180,000 Hefner candles.

The number 683 is connected to the modern (1979) definition of the candela, the unit of luminous intensity.

Prior to the definition of the candela, variety of units for luminous intensity were used in various countries.

I is the luminous intensity in candelas (cd),

I, symbol for the luminous intensity

It may, in certain cases cause luminous objects appear like cylindrical pipes with the same luminous intensity at all points.
