4 layers of commercial lighting
In this article I will talk about the rough division into four layers that are worth considering in commercial lighting.
This article doesn't claim that these are the only layers, but I can certainly say that anyone who has addressed these 4 has done his due diligence in finding a good solution for lighting a commercial space.
When I write "commercial space" my intent is a store, showroom, office and similar spaces. There are many other subcategories for defining spaces according to purpose, audience or people using these spaces.
It's good to know these layers as this helps in many cases that arise on the way.
I call these layers as that's how I see it in my head. This isn't a professional term but just the easiest way for me to explain it.
Layer 1: General lighting
The purpose of general lighting is to create the basic lighting level necessary to light the space.
Layer 2: Lighting points of interest
The purpose of this layer is to emphasize/highlight elements in the space. We direct visitors to look where we want. A display stand of special articles sold in the store, a show cabinet with samples in the office, design or art pieces on the walls, cars in a car showroom, you get the point...
We achieve this effect by using different levels of light between general lighting and directed lighting on the items we wish to highlight. This can also be achieved by using different lighting temperatures in the fixtures.
Direct lighting fixtures are usually characterized by a narrow, adjustable illumination beam of 20-40 degrees and we use
Layer 3: Designer lighting
The pieces that you select for this layer are design items in their own right. They have an effect on lighting the space but are also, themselves, part of the design.
These lighting fixtures have a definite presence. They are a design element hanging in your space. Don't forget that they also affect the lighting and must be taken into account in the lighting plan.
Layer 4: Emergency lighting
You can't avoid safety. Emergency lighting is not a design feature. These products are characterized in a minimalist style so as to affect the overall design as little as possible.
It is essential to install this lighting, as part of the overall lighting plan, to illuminate escape routes according to the building standard wherever your project is.
It is important to choose a lighting fixture with symmetrical photometry for an open space. For corridors, select a narrower, asymmetric beam. Along with the emergency lighting solution, you will usually install exit signs, and for this you should consult with the project safety advisor.
If you have an answer to each of these layers in your commercial space lighting plan, then you are probably covered.
I wish you successful commerce, and productive work in a pleasant, well lit space.
I wish us all good light!
