• Recognize the difference between OLED Light source all the conventional light
sources (including LEDs)
• Identify the major components of an OLED and understand the basic principles
of light emission
• Explain OLED performance and Photometric characters
• Define the Lighting Design Philosophy and Design Language for OLED
Lighting and the kinds of luminaire designs they enable
• Describe the current applications of OLED Lighting and its future direction
LEARNING OBJECTIVES

Bright, glary
They are intolerable
Cannot be viewed directly
Current Light sources

We create shades, diffusers, lenses, louvers and
parabolic cells to hide the light sources

PHILOSOPHY
Lighting design – complements 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
Compelling luminaires
Celebrating the source itself
PHILOSOPHY
OLED MOVES BEYOND FUNCTION…
IT IS ABOUT EMOTION
(Photo Courtesy: OLED-Info)
PHILOSOPHY
FORM FOLLOWS THAT EMOTION
SIMPLICITYDESIGN
This design demonstrates the unique
character of OLED lighting:
Nobility of light – it is simple, pure and
honest;
it allows LIGHT itself to become the luminaire
SIMPLICITYDESIGN
As evocative as a
candle flame
FREEDOMDESIGN
We can sculpt a ceiling with brightness and texture.
Luminaires deliver tailored light where needed.
Regimented layouts are a thing of the past.
EXPRESSIONDESIGN
OLED enlivens any environment with focal points of sculpted light
EXPRESSIONDESIGN
Light is the sculpture and focal point
lighting immerses the user in a soft volume of
light and creates a sense of companionship
and comfort
when mounted in close proximity, it
transforms the interaction within an interior
space to a more human and personal
experience
it invites us to gather
HUMAN CONNECTIONDESIGN

DESIGN INTIMACY
