Different Form Factors

SustainabilityArchitecture: GenslerLighting: Darrell Hawthorne / Architecture & LightPhotography: Nic Lehoux

• No mercury or other hazardous materials

• Thin and light. Reduced amounts of luminaire

housing materials.

• Reduces footprint of shipping and packaging

and disdposal

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.

PHILOSOPHY

OLED MOVES BEYOND FUNCTION…

IT IS ABOUT EMOTION

Approachable, welcoming , get close to, touch it and befriend it


IT IS ABOUT EMOTION

PHILOSOPHY


IT IS ABOUT EMOTIONOLED transform the lighting experience. It elevates lighting from

simply utility to something that resonates with our emotion.

FORM FOLLOWS THAT EMOTION

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

Design – Freedom

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.

“Who ever said that

pleasure wasn’t

functional?"
