IB-09 lighting design guide
IB-09 · LED
Deep architectural relief for a dramatic illuminated ceiling.
IB-09 has enough scale and modelling to hold its presence in tall rooms, even when the ambient LED layer is dimmed low.
Design and lighting guide
Designing concealed LED light with IB-09
The profile, source position and reflecting surface must be planned together. That coordination is what turns a hidden linear source into an architectural ceiling effect.
Let the profile geometry lead
Its deeper shape creates a strong separation between the beam face and the reflected ceiling wash. Controlled light on the upper plane can emphasize that depth without exposing the source.
Treat the strip, channel and diffuser as one system; confirm their setback and aiming with the selected components. The principle is related to architectural light coves, adapted here to the beams of a coffered or waffle ceiling.
Match the effect to the room
This is a natural fit for great rooms, formal reception spaces and high ceilings viewed across long distances.
Control the ambient layer separately from recessed spotlights or decorative fixtures so the room can shift from everyday use to a quieter evening scene.
Plan the concealed components
Confirm beam spacing and output at the room scale. Deeper coffers may require careful aiming and a sample run to avoid a bright line near the channel and a dark centre overhead.
Also establish wiring routes, driver location and access, heat management and dimming compatibility before the beam details are closed and finished.
