Lumen

Lumen: unit of the International System of Measurement, which is used to quantify luminous flux. A precise measure of the luminous intensity emitted by a light source..

Lux and lumen

Technical lighting concepts

Lumen as a seemingly simple concept is often intertwined with another term: Lux (lx).

It is important to understand the difference between lumen vs. lux for an accurate technical understanding in the field of lighting.

Mathematical relationship

Lux is equal to lumen per square metre

The relationship between lumen and lux is remarkable for its mathematical simplicity.

One lux is equivalent to one lumen per square metre. This direct connection between the two units enables an effective assessment of lighting in quantitative and technical terms.

The mathematical relationship between lux and lumen per square metre is essential to understand how the light emitted directly affects a specific surface.

Lux (lx), being the unit of illuminance measurement, provides valuable information about the amount of light incident on a given area. This concept becomes even more significant when it is recognised that one lux is equivalent to one lumen per square metre.

lux = lumen / m²

Practical example

To illustrate this, consider a practical example: if a lamp emits 500 lumens and that light is evenly distributed over an area of 1 square metre, the illuminance at that point would be 500 lux.

This direct relationship allows lighting professionals to precisely calculate the amount of luminous flux emitted by a light source to meet the specific requirements of a space, thus ensuring optimal levels of visible light.

The lumen-to-lux ratio per square metre is also critical in the design of efficient and customised lighting systems.

By understanding this connection, engineers can adjust the power of the light sources and their distribution to achieve uniform and appropriate illumination according to the particular needs of each environment.

This mathematical approach provides a quantitative basis for informed decision making in the design and implementation of lighting projects, ensuring not only a well-lit environment, but also efficient energy utilisation.

Ultimately, the lux-to-lumen ratio per square metre is not only a technical component, but a key tool for optimisation and efficiency in the field of lighting.

Lumen and Lux as fundamentals for optimal performance in technical lighting

Lumen and lux are two intrinsically connected but distinct concepts in the world of technical lighting.

Understanding the connection between the two units establishes a robust basis for the planning and realisation of lighting projects, ensuring efficient results and optimal luminous efficacy.
