IB-04 lighting design guide
IB-04 · LED
Layered moulding, softened by concealed LED light.
IB-04 uses stepped detail to create depth in daylight and a controlled hierarchy of shadow after dark.
Design and lighting guide
Designing concealed LED light with IB-04
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 light should reveal the stepped profile rather than flatten it. A hidden source aimed toward the ceiling keeps the moulding readable and lets the brightest area remain above the beam.
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
The result suits transitional dining rooms, tailored living spaces and interiors that balance traditional trim with a cleaner overall composition.
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
Protect the visible faces from direct spill, especially at intersections. Match channel position and output around every corner so the illuminated ceiling reads as one continuous plane.
Also establish wiring routes, driver location and access, heat management and dimming compatibility before the beam details are closed and finished.
