LIGHTING
interiors, bespoke furniture and decorative lighting. As a pendant, OLED can be used to recreate a traditional incandescent but brighter and more energy efficient, without glare or heat.
In its flexible form, Applelec’s OLED modules boast a bending radius of 20mm and a thickness of just 0.41mm, enabling it to be made into coils or waves without adding any significant depth to the design.
Applelec recently supplied materials for a stunning art installation which combined OLED technology with 3D printing for the London Design Festival. The Ribbon created by lighting artist Min Sang Cho, was featured at the festival before being installed at its permanent home at the Genting Highland Casino in Malaysia.
“It’s not unusual for FMs to
report savings on energy bills of around 75%.”
The Ribbon explored both the artistic possibilities presented by OLED while maximising its advanced technology. First, the installation was 3D printed before being manipulated into shape then finished by hand. 24-carat gold leaf paint was applied to each piece of ribbon to emphasise the soft, ambient reflections from the OLEDs.
The installation can be altered in size and shape, with each measuring 1.2 metres when straightened. One segment features three flexible 400mm x 50mm OLED panels on one side while the other side is hand-painted with gold leaf. Power consumption is impressively low, with the installation drawing just 9W per unit.
High versatility, low-power consumption The ability of LEDs in general to reduce energy usage and costs is well known. Currently, they are often the first choice for many facility managers looking to reduce high electricity bills; it is not unusual for managers to report savings on energy bills of around 75%.
OLED technology is capable of achieving even more impressive efficiencies than most LED schemes. With regular LED modules, the backlight is never actually turned off but is blocked, producing the colour black when the pixel shutter is fully closed.
An OLED has no backlight, and turns the pixel off entirely to produce black, therefore it consumes zero power.
At the moment, OLEDs are considered by many too expensive to use for general lighting schemes, while the organic materials have a limited lifetime. However, moves are being made to prolong their lifetime, with some already capable of reaching 10,000 hours or above. The technology is, however, relatively young and it has already opened up a world of possibilities for designers and architects alike.
