Industry-recommended light levels.
Correct ilimuniation should be fundamental in our work areas since this prevents eye fatigue, tiredness, stress and above all improves employee productivity and most importantly prevents accidents in the work area in all kinds of Industries.
Good lighting combines three aspects: high luminous efficiency, long service life and good color reproduction. Lighting of industrial premises must:
- Facilitate the execution of a task: the concept of visual performance.
- Normal vision can only be exercised in minimal light. A good lighting level allows for good productivity, which means fewer errors or accidents and reduces visual fatigue.
- Ensuring well-being: the fundamental concept of visual comfort.
In addition to the required lighting level, it is also essential to ensure the following:
- A good quality of light emitted by sources.
- The uniformity of the lighting.
- The proper lighting balance to avoid glare in particular.
- Illuminating industry work areas.
The level of illumination must be adapted to the nature and precision of the work to be done. To illuminate the work area, it is recommended to use local lighting, adapted to complement the general lighting of the facilities.
For indoor circulation: Minimum illumination of 40 lux.
For changing rooms and bathrooms: Minimum illumination of 120 lux.
For blind premises assigned to permanent work: Minimum illumination of 200 lux.
For taxiways: Minimum illumination of 10 lux.
For outdoor areas assigned to permanent work: Minimum illumination of 40 lux.
Lighting for specific work areas:
For average office and office-based typing jobs: 200 Lux minimum illumination
For machine processing and drawing work in the office: 300 lux minimum illumination
For fine mechanics, engraving, drawing and color comparison: Minimum illumination of 400 lux.
For precision engineering, fine electronics and various controls: Minimum illumination of 600 lux.
The level of lighting required in the industry depends on:
The size of the details to be observed. The contrast between the object/shape and the bottom (the greater the contrast, the greater illumination is required).
The following aspects should also be considered:
The speed of execution of the job.
The movement of monitored objects (the faster the movement, the more lighting is required) The age of the operators.
In industries that require precise and precise mechanical tasks, as well as in the electronics industry, specific lighting reinforcements must be installed on workstations. Some industrial sectors, in particular the chemical sector, require the use of protected luminaires.
Industries where chromatic reproduction is extremely important, such as the printing industry, require the use of suitable lighting lamps. In other industries, such as the manufacture of paints, plastics or resins, the industrial process requires the use of special types of UV rays or IR light emissions.
