Lighting design – enhance the visual experience of
the occupants and brings architecture to life with or
without the visual presence of luminaires.
With OLED lighting, luminaires are more central to our
focus and our consciousness.
They are meant to be seen and celebrated.

Thinness
A luminaire with form but without volume. Celebrates what is not there.
OLED is hi tech, the design is comfortable & familiar
Light is the star. Everything else is receded to the background
6/10/2016
13
For a luminaire that connects with us,
its design, its brightness, it form, and its gesture has to be sympathic to our emotion
OLED releases us from the rigor of regimented layout. Such as 8x8 or 8x10.
You are free to put light where you want to. Regimented layouts are a thing
of the past

AbstractTask -Ambient lighting provides energy saving but space surrounding the users can be dim and unpleasant. This study
proposed a solution of an additional Surround Layer of light. Though a series of simulated lighting scenarios,
it examined illumination requirements, dimensionality and appearance of the space by the use of Vector/Scalar and
Task/Vertical Illumination Ratios.
They were evaluated under several illuminance requirements, Task-Surround combinations and Surround Light source
sizes. The results showed that by adding a Surround Light Layer, visual appearance of space surrounding the users
could be enhanced and energy savings could be achieved.

“Any time of day or night, the effect of the luminaires is stunning. Clients – including lighting designers,
architects, engineers, contractors, distributors and owners – have a similar reaction.
“When I hear them say ‘Wow’, one might think they are simply referring to our amazing view. But I know
it’s the lighting!” - Ayse Aktari, 16500

“I love that Trilia OLED luminaire allows you to have a connection to nature. It hints back to
something more organic, more inspiring. There is something about this particular product that
lends itself to a creative connection. When visitors are in our space, they are often so intrigued
that they ask to physically touch it.”
- Leslie North, Aurora Lighting Design
OLED system delivered much
higher quality lighting
in spite of a few field issues.
Approximately 2 months after installation
was complete, a driver failed and was replaced; 2 months later, an OLED
panel failed and was replaced. The
only unresolvable issue is photometric flicker of approximately 77% to 100% at
261 Hz
produces high vertical illuminances
on surfaces (such as walls) and
excellent facial modeling; a soft
light distribution that reduces harsh shadows from objects
The installation was time-consuming because the contractor had not installed
such a system before, and because of
the high level of precision required to
locate mounting points in a limited-
access ceiling, and the complexity of the wiring between the panel sections
and the many drivers
very pleased with the finished appearance and function of the OLED system. They made
positive descriptive comments
about the lighting, such as “soft,” “inspiring,” “desirable uniformity
of light for the office

The Power of OLED Lighting design is not just looking great.
It is functional and touches our emotion.
And we embrace it with pleasure.

pleasure wasn’t
functional?"
