codes, minimal power achieves comfortable illumination while also
providing the clients with controls for bright, cool summer evenings
or cosy, warm winter nights.
Shadows on the back side of the translucent acrylic would have been
visible from below. Instead of using thick, opaque formwork to support
the acrylic, a tab-and-slot L-panel system was devised. Each piece hangs
by two thin suspension wires and interlocks with the piece below it.
If the LEDs had been mounted to the roof and directed downwards,
the suspension wires would have cast thousands of shadows on to the
translucent acrylic. Instead, the LEDs aim upwards, floating between the
roof and the sculptural ceiling on clear acrylic sheets. This effectively
converts the roof’s underside into a massive light box that disperses
direct rays off its flat white paint. Cast shadows are eliminated and diffuse,
indirect illumination is radiated to the room below.
Once the sunroom’s shell was constructed, it was necessary to relocate
across country to the project site. Flynn A&D worked with the client
to fabricate and install the entire ceiling sculpture. ( Watch the process
online at vimeo.com/183087759). Pre-drilled plywood panels were
painted and filled with more than 1200 eye bolts. The plywood was
then fastened to the underside of the roof rafters and 5000ft (1500m)
of suspension wire was attached. Hanging below are 128 clear acrylic
panels, supporting more than 29,000 LEDs connected by 7000ft (2150m)
of electrical wire. Using custom bending tables, 397 uniquely shaped,
CNC-cut, translucent pieces were thermoformed on individual angles.
These were hung within a 1/32in (0.8mm) tolerance to complete the
ceiling. The result: a curvilinear, translucent, backlit, full-room suspended
ceiling that bathes the sunroom in relaxing, diffuse light.
A specially devised tab-and-slot system ensures the absence
of shadow, effectively turning the ceiling into a lightbox
