Introduction to Philips and Osram OLED lamps

  1. Philips (Europe) Lighting has been exploring the potential technology of OLED and the company’s strategy to enter this technology field. The technology has now been applied to make panels most suitable for artistic exploration, the most dynamic of which is the curtain wall, an interactive light wall containing hundreds of OLED panels, introduced at the European Lighting Exhibition in 2009. Earlier, Philips has started to sell its OLED-based Lu mi blade lighting chips, but before the OLED, the market has not moved much]. In 2010, Philips began to launch commercial products. Features of Philips panels:

1) Size: diameter 11.9cm×3.7cm×2.3mm;

2) Efficiency (typical value): 15~20lm/W;

3) Material type: small molecule OLED (emission layer);

4) Color temperature adjustable (3200K) and RGB color adjustable;

5) Brightness: 3000cd/m2;

6) Life (typical value of LT50): about 10000h@1000cd/m2;

7) CRI (typical value): 80;

8) Shipment time: the fourth quarter of 2010.

  1. OSRAM Corporation (Europe)

OSRAM Opto Semiconductors, Regensburg, Germany, has been promoting the development of OLED technology, and the company recently launched Orbe os light panels in Europe [147]. These panels are “market-ready” for integration into lighting applications and are now available in the US market. In November 2010, Osram produced the first OLED lighting fixture [148]. The circular Orbe os OLED lamps have a brightness of 1000cd/m2 and a service life of more than 5000h. At present, Osram is focusing more energy on research and development of OLED lamps for general lighting. The focus of OLED research and development is white OLED, as it is the most commonly used indoor lighting fixture.

The company’s goal is to produce white OLED lamps with a luminous efficacy of 251m/W at the appropriate current.

Features of Osram’s panels:

1) Size: diameter 88mm×2.1mm;

2) Efficiency (typical value): 231m/W;

3) Material type: small molecule OLED (emission layer);

4) Color temperature adjustable (2580~3320K) and RGB color adjustable;

5) Brightness: 1000cd/m2@186mA;

6) Life (typical value of LT50): 8000h;

7) CRI (typ.): 75.

Osram expects to mass-produce OLED lighting products until 2016. It transitioned to high volume in 2012 by selling to design groups, where target customers would value some of the product’s unique features, such as transparency.
