Each activity requires a level of illumination, the greater complexity of the task increased need for lighting. How lux illumination is measured and how to know how much light do I need? Espaciohogar you what we have video.

How to measure illuminance in Lux

The lux (lx) and the lumen (lm / square meter)

The lux is the unit for measuring illumination level. Photometry this measure is used to calibrate the light sensitivity of the human eye. Equals&# 160; one lumen per square meter. The difference between the lux and the lumen s lux takes into account the surfaces where the light flux is distributed, the lux measured incidence of light impinging on the surfaces.

How did lux measured?

The lux measured with a measuring device called the lux meter, which converts light signal into an electrical signal which is amplified and subsequently allows the intensity reading on a calibrated scale of lux

Before the measurement is calibrated dial 0. the device is expected about five minutes before the measurement. Measurements are made with furniture, equipment or personnel (for office) in their usual positions.

How to measure illuminance in Lux

To know the level of illumination in a specific place where it runs a task is measured at the level where it is performed. If utility is measured at 85 cm from the ground. In roads it measured at ground level.

Recommended lighting levels

Depending on the task is&# 160; need more light because it is not the same visual perception for precision tasks that others do not. The Normalizer European Committee establishes recommended lighting levels.How to measure illuminance in Lux

  • special visual tasks such as surgery:&# 160; between 20,000 and 10,000 lux

  • extraordinarily demanding visual tasks (microelectronic assemblies: between 7500 and 5000 lux

  • time-consuming tasks that require precision (horological):&# 160; between 3000 and 2000 lux

How to measure illuminance in Lux

  • Visual tasks with specific requirements (prints, sewing):&# 160; between 1500 and 100 lux

  • Tasks with normal visual requirements: 750 to 500 lux

  • limited visual tasks:&# 160; between 500 and 200 lux

  • Areas not intended for work, storage, access roads: between 150 and 100 lux

  • Lighting areas to guide visitors short mode: from 75 to 50 lux

  • between 30 and 20 lux: open to public access areas with dark surroundings
