Luminous intensity A part of the light flux emitted in one direction.

Luminous intensity A part of the light flux emitted in one direction.

Luminous intensity is a part of the light flux emitted in one direction. Measured in candelas (cd).

It characterises the density of the light flux and the magnitude or quantity of light energy transmitted in a certain direction per unit time.

The narrower the beam angle, the more luminous intensity. Expressed with the luminous intensity distribution curve.
