Notes:
Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eye-response curve. The dominant wavelength (λd) is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.
It is widely used in display screen function, including pattern display.
