A Closer Look at OLED Lighting Perspectives for Phosphors

Smithers Apex interviewed Peter Ngai, Vice President of OLED Research and Development, Acuity Brands Lighting on the future of OLED lighting perspectives.

March is approaching fast and before you know it you'll be lounging at Paradise Point preparing for the Phosphor Global Summit 2014! This conference will provide the most comprehensive look at the industry and is the most well respected summit in the industry. From sessions on OLED Lighting Perspectives, the evolution of the LED industry, High Luminance Applications, plus many more, we have the information you need to compete in 2014!

Peter Ngai's presentation will compare OLEDs to traditional types of light sources and set the performance benchmarks required for lighting design. He will also describe the character of light from OLEDs and analyze the designs they enable. We asked Peter a few questions on what makes the OLED technology stand out in lighting, the evolution of new lighting philosophies, and the role phosphors play in OLED lighting.

In your opinion, what makes the OLED technologies stand out when it comes to lighting applications and where do the opportunities and challenges lie for mass implementation and adoption?

OLED lighting today is ideal for applications where the impact of a strong design statement is a critical part of the project, such as in specialty spaces in corporate interiors, lobbies, retail, or hospitality spaces. It is also ideal in applications where users can interact with the light or where the light is close to the users - think of task lighting, mirror lighting, and luminaire types such as sconces and decorative pendants. Of course, efficacy and lifetime are improving rapidly with OLED, and we expect these performance attributes to be on par with LED in the next few years. It will certainly broaden applications, and enable the core character of OLED be appreciated on a larger scale and be applied in more types of applications such as general office, healthcare, and residential. The biggest challenge OLED faces for mass implementation and adoption is bringing down the cost. We expect cost trend of OLED will be similar to that of LED. As OLED becomes more and more affordable, the almost limitless design possibilities and superior lighting quality will enable new classes of luminaires, promote new ways of integrating light into interiors, and evolve new lighting design techniques.

What role does Phosphor play in the development of OLED lighting technologies?

OLED contains separate RGB emitters and does not require phosphors. However, OLED is competing with LED based on color quality so the understanding of the efficacy/ color quality (CRI Ra and R9) trade-offs in phosphor converted LEDs are important.

Can you explain briefly how do you see new lighting philosophies evolving and coming into life?

Some of unique the characters of OLED are that it is thin, calm, cool to touch, perfect light diffusion as well as possibly transparent and flexible. These characters bring imagination and creativity which will be the spark to innovate new lighting philosophies. As more and more designers work with OLED, we will see the landscape and language of lighting design evolve from a practice that relies upon specification of luminaires to one that celebrates lighting with light, that enables us to humanize light, that encourage us to interact with light and simply have fun playing with light.

What are you looking forward to hear at the Phosphor Global Summit 2014?

OLED developments if any; user studies of LED color quality; and overall advances in phosphor development
