What is a lux meter?

A lux meter is a measuring device to know how much light or luminosity there is in an environment with which light appears in the human eye. It is not the same as measuring the energy produced by a light source. The unit of measurement is lux. A lux is the equivalent of the energy produced by a light source, for the human eye.

How does a lux meter work?

The operation of the lux meter is simple. This depends on photovoltaic cells, an integrated circuit that, when receiving a certain amount of light, are able to transform them into electricity. Depending on the intensity of the electricity, the amount of lux is known.

Luxometerscan have different scales depending on the amount of light you want to measure, to have a more accurate accuracy in case the luminosity is stronger or weaker.

How to use a lux meter?

As a first step, the photoreceptor, a piece that receives the light, must be placed in the direction of the light source that you want to measure.

As a second step, we must place in the luxometer reader the appropriate scale depending on how strong or weak the light is. For example, if you want to measure moonlight, it should be a scale close to 1 lux. On the other hand, if you want to measure the sunlight of a room, we need a scale close to 1000 lux.

Once everything is ready, you should press the power button of the reader, wait a few seconds until the reading appears.

Once the reading appears, the number is multiplied by the chosen scale. Example if we choose a scale of 100 lux, and the measurement was 30 the value is 30*100 = 3000 lux

Parts of a lux meter

A photoreceptor. It is responsible for perceiving the light intensity to be measured, and transforming it into electrical energy, which is then transported to the reader. Part of a photoresistance.

A reader. It is responsible for receiving the electrical signal sent by the photoreceptor and transforming it into a measure of luminosity. Then this measure is indicated on the screen.

Applications of a lux meter

Filmmakers and photographers. The lux meter was created in order to improve the luminosity in films and photographs.

Energy producers. They use lux metersto optimize the use of light indoors and outdoors.

Meteorology. It measures the light in the sky, or that received by the soils of cities, fields, forests or greenhouses.

Hygiene and safety. Industrial measurements for Occupational Risk Prevention,

It is used to check if any workplace could adversely affect workers either because of its high or low amount of light. In this way, the correct lighting of workspaces can be ensured in any type of productive sector, whether factories or offices.
