LuminousIntensityUnit enum

Represents units for luminous intensity.

This enum implements the Unit interface to provide conversion capabilities and a display symbol for each luminous intensity unit. All conversion factors are pre-calculated in the constructor relative to Candela (cd), which is the SI base unit for luminous intensity.

Values

candela → const LuminousIntensityUnit

Candela (cd), the SI base unit of luminous intensity. It is defined by taking the fixed numerical value of the luminous efficacy of monochromatic radiation of frequency 540 × 10¹² Hz, Kcd, to be 683 when expressed in the unit lm W⁻¹, which is equal to cd sr W⁻¹ or cd sr kg⁻¹ m⁻² s³.

const LuminousIntensityUnit(1, 'cd')

millicandela → const LuminousIntensityUnit

Millicandela (mcd), equal to 0.001 candelas. Commonly used for LEDs and indicator lights.

const LuminousIntensityUnit(LuminousIntensityFactors.candelasPerMillicandela, 'mcd')

kilocandela → const LuminousIntensityUnit

Kilocandela (kcd), equal to 1000 candelas. A less common unit, might be used for very high-intensity light sources like searchlights or lighthouses.

const LuminousIntensityUnit(LuminousIntensityFactors.candelasPerKilocandela, 'kcd')
