minimise shadows in the corners and to evenly
illuminate each window blind. LDC built a mock-up in Madrid to test three different combinations of
optics and holographic diffusers, finally choosing
elliptic optics. The new fixture control was designed
to allow soft movements of light. The 320 linear
luminaire and 20 corner luminaires have a total of
7360 RGBW LED chips; every two chips or 120cm
can be controlled individually resulting in 3680
pixels with four channels. The software developed
for lighting control enables the client to change the
lighting with an online app from any location.
The lighting content is arranged in three families. The
first, titled Geometric, is inspired by the architecture.
Weather incorporates real-time temperature, wind
and humidity data collected online. For example, cold
temperatures result in cooler tonalities and increases
in wind speed make the patterns move faster. The
third content family, 8 Bit, plays with the facade grid
and treats each window as a pixel.
The control system allows soft
movements of light. The client
can change the scene from any
location using an app which
controls nearly 7500 LEDs
