Unit Information

Learn about the illumination units you're converting between

Lux

Definition

The Lux is the SI derived unit of illuminance, representing the luminous flux per unit area. It measures the amount of light that falls on a surface, with one lux being equal to one lumen per square meter. This unit is fundamental in lighting design and photometry.

History/Origin

The lux was established as part of the International System of Units (SI) in 1960, derived from the candela and meter. It replaced earlier illumination units and provides a standardized way to measure light levels for various applications, from architectural lighting to scientific research.

Current Use

Widely used in lighting design, photography, workplace safety standards, and scientific research. It is essential for determining proper lighting levels in buildings, outdoor spaces, and industrial environments, ensuring adequate visibility and safety.

W/cm² (at 555 nm)

Definition

The Watt per Square Centimeter (at 555 nm) is a unit of spectral irradiance that can be converted to illuminance at the peak sensitivity wavelength of the human eye. It represents the radiant power per unit area at 555 nm, weighted by the luminous efficacy of radiation.

History/Origin

Developed for converting between radiometric and photometric quantities at the peak sensitivity wavelength of human vision. It provides a bridge between physical light measurements and perceived brightness, using the luminous efficacy of 683 lumens per watt at 555 nm.

Current Use

Used in optical engineering, laser technology, and display characterization where the relationship between radiant power and perceived brightness is important. It allows for precise conversion from physical measurements to photometric quantities for monochromatic light sources.
