• 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

W H Y O L E D I S D I F F E R E N T

CALM SOFT COMFORTABLE TO LOOK AT

Bright, glary

They are intolerable

Cannot be viewed directly

Current Light sources

OLED

We create shades, diffusers, lenses, louvers and

parabolic cells to hide the light sources

LET THE LIGHT BE FREE

No longer is the light confined to a restricted design or scale

Free from the bondage of traditional shapes and sizes

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

Sensitive designs that encourage you to come closer
