Optimal placement of light spots on the ceiling and wall

Intro

The correct distribution of light spots on the ceiling is essential to ensure visual comfort, highlight elements of the space and avoid unwanted shadows. In interior architecture, the lighting design must consider the layout of the furniture, the function of each zone, and the presence of moldings, curtains or decorative elements on the ceiling.

General lighting (central light)

Single light spot, generally centered on the room.
In living rooms and bedrooms, it can be replaced with multiple built-in spots, evenly distributed.
In square spaces, the geometric center of the area is often sufficient.
In rectangular spaces, consider the most functional area as a reference (e.g., living or sleeping area).

Distribution of embedded spotlights (spots)

Recommended spacing of 1.20 m to 1.50 m between bulbs, depending on intensity and type of lamp.
Distance from walls: starting at 40 cm, to avoid shadows and highlight curtains or decorative walls.
In corridors or passage areas: linear distribution with foci at each 1.5 to 2 meters.

Spots of light on curtains or curtains

To highlight fabrics and create soft indirect lighting.
Recommended position: 10 to 15 cm away from the molding or the beginning of the curtain.
In LED-illuminated moldings, provide a hidden connection point on the ceiling or side of the molding.

Lighting over dining tables

Center of the light spot should align with the center of the table.
If the table is extendable, consider adjustable hanging light or multi-focus rail.
Lamp height: between 70 and 90 cm of the table surface.

Light spots in the toilet and kitchen

Kitchens: built-in spotlights distributed over work areas (islands, countertops, dishwashers).
WC: center point + specific mirror lighting (it should not be the only light point).
In both cases, avoid placing lights directly on wet areas without adequate protection (use luminaires with IP44 rating or higher).

Special cases: uneven or sloping ceilings

On sloped ceilings, the light spot must respect the vertical of the useful area (avoid touching the sloping wall).
To highlight the ceiling architecture, adjustable rails or lights embedded in false planes can be used.

Tips for planning ceiling lighting

Define the furniture layout first and only then the lighting plan.
Use lighting scenarios: general light + accent light + ambient light.
In bedrooms and living rooms, consider indirect light for moments of relaxation.
ensures easy access to maintenance points and provide ceiling recesses to embed elements.
Anticipate the type of luminaire (built-in, suspended, ceiling) for correct sizing.
