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.

Nox

nox

Definition

The Nox is a unit of illuminance equal to one-thousandth of a lux, representing very low levels of illumination. It is used for measuring extremely dim light conditions, such as those found in night vision applications, astronomical observations, or specialized scientific measurements.

History/Origin

Developed for measuring very low illumination levels that are below the practical range of the lux. The nox provides a convenient unit for expressing extremely dim light conditions in scientific and technical applications where precision is important.

Current Use

Used in specialized applications requiring measurement of very low light levels, such as night vision technology, astronomical photometry, and scientific research involving extremely dim light sources. It provides a practical scale for quantifying near-threshold illumination conditions.
