Ashford-Smit says the concept of using geo-
metric patterns of light and colour sequencing to
transport visitors to a radical new world is very
successful. The different colours and contrasts
subtly change the atmosphere; chromotherapeuti-
cally stimulating a variety of feelings, moods and
emotions; disrupting circadian cycles and keeping
people awake and stimulated. This is the oppor-
tunity a casino affords, and is what differentiates
Times Square from all the others.
The LED channels are populated with RGBW
LEDs on a circular download. The installation
cycles through 26 scenes each day to create the
chosen spectrum and, according to Ashford-Smit,
the cross-fade between colours is so seamless it
is barely noticeable.
Lighting control was central to the success of
the installation, not only for the scene changes and
dimming control but also to achieve the maximum
energy saving. Triac used the Intellibus system, a
South African designed and manufactured digital
lighting control system. Bespoke PWM dimming
panels control the RGBW LED channels, whilst
Intellibus LED low power dimmer modules control
all the LED downlights.The four-channel PWM dim-
