While I am not going to talk about making movies, I am making an analogy with the long and winding road to finally get to where you want to get to. Finding the right lighting solution (“Nemo”) can be a long and arduous route. Today I had a lighting design session that felt a bit like finding “Nemo”. I know what I want to achieve as final lighting effect, a basically simple uniform vertical wall wash in a high void building atrium together with proper lighting levels in the atrium. The ceiling is about 4 stories high, but the lighting design is a bit complicated by firstly a mezzanine floor protruding from the wall half way into the atrium at the 3rd floor and secondly a tilted glass window frame which cantilevers out about 3m from the ground floor plan, in other words the ceiling plan is larger than the floor plan.
We are on the same page as the architect in that we do not really want the lights to be seen but rather the resulting effect in the space. So the principle concept calls for linear coves that will recess/ hide the downlights out of view. However two major challenges need to be overcome. First we want an even uniform wall wash, right from the top of the wall, no scalloping. Second we are dealing with the sloped window pane which potentially can create irritating reflected glare. So obviously it is about location, location, location and optics, optics and optics.
I generally work backwards (well in my vocabulary it is forward) when designing looking at the lighting effects/ moods that I want to achieve first, then working my way back(for) towards the lighting fittings that will be able to do the job. This then impacts on location and installation details, such as layout, spacing and dimensions. We have come up with a couple of options which we now work out in terms achieving the desired lighting levels and uniformity, with quality to determine quantity!
Light & Learn 3-18: Here are some of the wall wash solutions we have been investigating. We have not decided on the final design solution, though I have a pretty good idea what we will select. Final decision will be made once we have weighted the costs and energy loads of the options. Sustainability remains key to every solution!
