a high CRI (>90) and just 1mm (yes, one millimetre) thick. This single panel is capable of a maximum 1,000lm output and a 40,000 hour lifetime. Interestingly, LG Chem has continued to develop flexible OLED based light sources and in order to reduce pricing they have focused on adding plastic substrates based versions which will become commercially available in 2015. These new plastic based flexible OLEDs will be super-thin at only 0.3mm thick, lightweight <5g, bendable, twistable and at the same time infrangible. Although I wonder exactly what mass produced lighting will need such flexible OLEDs, they certainly will allow lighting designers to stretch their imagination as to the potential uses of such light sources. LG Chem highlighted how OLED flexibility could be used for task lighting and light art. The LG OLED task light can also be controlled by smartphone using iOS and Google Android Apps. I know you will be saying that OLEDs may meet the technical specifications required for lighting but the costs are excessively prohibitive. LG did state the costs of OLED panel would drop significantly now that they have reached technically acceptable levels and I believe costs will drop by 50 to 80% over the next few years allowing a rapid penetration in certain market segments just as LEDs did in their early evolution. I wouldn’t put it past LG Chem to deliver a 140lm/W 600mm x 600mm OLED panel by Light + Building 2016!

rooms, where lighting is used as a design statement to create an exclusive ambience.

so that Acuity are expanding their commercial OLED team to take advantage of the expanding market which points to a realisation the OLED technology is becoming acceptable for general lighting markets.

PHILIPS Philips launched its new OLED Lumiblade Panel Brite FL300 which is a highly flexible OLED panel ideal for customised designs. This new panel offers 300 lumens output over a 12cm2 area with an increased efficacy of 50 lumens/W and will be available by the end of 2014 in two colour temperatures of 3,000 Kelvin and 4,000 Kelvin. The Lumiblade panel brite FL300 is rated to last 10,000 hours at full brightness and is designed for environments such as high-end shops and hotels, as well as office spaces such as executive board

OSRAM OSRAM showed an OLED concept suspended luminaire designed by Werner Aisslinger equipped with 16 square SDW-058 OLED panels based on the latest generation of the ‘Orbeos’ OLED panel. The new Orbeos OLED panel is already more efficient than energy-saving lamps and the performance improvement compared to the previous generation is +50-75% on lm/W, lifetime and lux output. These latest OLED panels can achieve 600 lux and 65lm/W with a lifetime of 15,000 hours, which is just ahead of Philips latest devices but behind those exhibited by LG Chem. ACUITY One of the largest pure play lighting companies, Acuity Brands has been focusing on OLEDs for several years and they showcased its latest generation of OLED luminaires. Three commercially available OLED luminaires – Trilia, Revel and Canvis - used the LG Chem OLED panels to unlock functional but artistic possibilities to enhance human relationships with lighting. The OLED luminaires can be used in a variety of spaces such as office, retail, hospitality and restaurants. They are offered in three colour temperatures - 3000K, 3500K and 4000K – with a CRI of 85 to 90. The Canvis OLED luminaires allow freedom to sculpt and define the shape of a space and provides substantial lighting. The Trilia OLED luminaires are modular units that allow designers to shape single or expansive networks of OLED lighting and create an exquisite interplay of symmetry and asymmetry. Speaking with Pete Shannin, Acuity Brands Lighting General Manager and Vice President, OLED Business Group he confirmed how focused Acuity are on their OLED business and stated that the three luminaires shown demonstrate that OLED lighting has made significant advancements and is now commercially viable.

KONICA MINOLTA Konica Minolta has been making R&D progress on commercialisation of OLED lighting, as it utilises the company’s unique core phosphorescent emitter materials. Konica Minolta has developed the world’s most efficient OLED lighting panel - achieving 131 lm/W over an emitting area being 15cm2. Konica Minolta presented the pioneering R&D results including the announcement of the OLED lighting panels with the world’s first colour tuneable function within an exhibition entitled ‘The cradle of life’. The Irodori display demonstrated an OLED lighting panels that rotated slowly and dynamically changed colours. The Ibuki display contained the world’s thinnest flexible type OLED at only 70-microns thick (or 30% thinner than a human hair). The OLED panel is so thin and light that it was shown floating in the air fanned by wind. Konica Minolta also invested in a new Japanese OLED production facility focusing on high-productivity roll-to-roll manufacturing methods. The facility will be able to manufacture up to 1 million panels per month and is set to deliver the new Symfos OLED panel range. One of the perceived advantages of rollto-roll manufacturing of OLED devices is the large reducing in production costs and
