When interior spaces are illuminated, many design techniques can be used. One of the most efficient ways in terms of energy saving, which also provides a pleasant environment, is the use of layered lighting.
For layered lighting we must basically take into account that each layer is responsible for a specific function. For example, in a museum, there is usually a general lighting with a low intensity, and additionally you can find a more accentuated lighting, with a greater intensity, to highlight the objects that are displayed.
Currently, modern buildings use layered lighting, where four main layers are used, being able to remove some or add another layer depending on each specific case. These layers are organized in such a way as to show the most general lighting (for the whole place) as well as layers for specific uses.
These layers are usually the following: natural lighting, general lighting, emphatic lighting and work lighting.
The first of the layers, natural lighting, depends almost 100% on the architect and the design of the place, since it involves the way in which natural light is used in the environment under study (blinds, windows, etc.)
The second layer would be general lighting. It consists of the lighting of the whole environment with artificial light. In this case you can either use direct light (downlights, fittings, panels, strips) or indirect light (LED strips).
After the general lighting, we have the layer of accent or emphasis, where we want to highlight objects or specific places. For this purpose we can use spotlights with a narrower beam angle, track lights, wallwashers, downlights, flood lights, among others.
Finally, we have the work lighting layer, where we use luminaires that provide an average level of lighting suitable for work (reading, writing, textiles, mechanics, etc). In this case we will study the working surface and use hanging lamps, wall fittings, desk lamps, flood lights, track lights, or any other option that may apply, to increase the average lighting on those work surfaces.
In short, when planning the lighting of indoor spaces, several factors must be taken into account, because people’s state of mind is closely related to the level of average lighting in the work area. Layered lighting is the easiest way to focus on all the factors, where each layer is responsible for a part of the lighting.
