Lighting systems
The interest in natural lighting has increased recently, due less to the quality of illumination obtained than to the well-being it provides. But since the level of illumination of natural sources is not uniform, an artificial lighting system is necessary.
The most common lighting systems are:
Uniform general lighting
In this system, the light sources are evenly distributed, regardless of the location of the workstations. The average IL luminance level must be equal to the level of illumination required for the task to be performed. These systems are mainly used in workplaces where workstations are not fixed.
They must comply with three basic characteristics: the first is to be equipped with anti-glare devices (scrolling grids, diffusers, reflectors, etc.), the second requires to distribute a fraction of the light towards the ceiling and the upper part of the light. Walls; the third involves installing the light sources as high as possible to minimize glare and ensure as homogeneous lighting as possible
This system attempts to reinforce the overall lighting scheme by placing the lamps near the work surfaces. As lamps of this type are often dazzling, they should be equipped with reflectors installed so that the light source is out of the worker's field of vision. The use of localized lighting is recommended in cases where the visual requirements are very high, such as those requiring lighting levels of 1,000 lux or more. In general, visual performance deteriorates with the age of the worker, which makes it necessary to increase the level of general illumination or to supplement it with localized lighting.
Localized general lighting
This type of lighting consists of ceiling lights that are split keeping two things in mind - the features of the equipment and the lighting needs of each workstation. This type of lighting is well suited to places or work areas that require a high level of illumination and requires knowing the precise location of each workstation even before the study phase.
