According to NVC, there are several stages in the lighting design process:
First, we divide the area into zones, each with its own function, desired lighting effect and range of fittings to be used.
Next we consider the illumination levels required on horizontal and vertical surfaces, before looking to ensure that glare is minimised.
Based on the light distribution plan we are now ready to simulate the illumination of the horizontal surfaces in the store. Using the photometric data we have for every fitting (.ies files) we model the effect of the fittings using Dialux.
We then repeat that process, looking at the vertical surfaces, taking into account the quantity, beam angle, wattage and precise angling of individual fittings to ensure that the desired effect is created.
Lighting design simulation
Using software we simulate the effect of the type, quantity and output of the fittings we have selected in a 3D model. At this stage we will discuss the results with the client and adjust the fittings if required.
For example, with an average illumination of 1,000 lux, the product display areas will be lit to 1,500 – 2,000 lux. These figures meet the light levels specified at the area illumination planning stage.
Of course, this is not always the case and we often have to revise the design to meet the criteria established at the start. Finally, when we are satisfied with the simulation we are ready for the next stage.
Prevention of reflected glare
We take care with the projection angle of light fittings, especially when they were illuminating reflective surfaces, to avoid any reflected glare.
It’s critical to consider how the lighting can weaken and strengthen space, so in product display areas we used high levels of illumination, creating a dramatic contrast with the ceiling to attract attention and create an exciting environment.
We can also chose fittings with a black body, mounted on black lighting track on a black painted ceiling to conceal their presence.
