Design and lighting guide
Designing concealed LED light with IB-15
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
The lit area should begin behind the upper ledge and blend upward. Keeping the front and side faces opaque preserves the strong stepped outline instead of making it look washed out.
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
Use the profile in feature rooms, generous residences and hospitality interiors where the ceiling is intended to be a focal point.
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
Intersections need special attention: carry the hidden source continuously while masking any spill that crosses onto the visible beam faces.
Also establish wiring routes, driver location and access, heat management and dimming compatibility before the beam details are closed and finished.
