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.
