OLED lighting

OLED is the acronym of Organic Light Emitting Diode (organic light emitting diode) and indicates a technology that will mark the future of lighting for many operators in the lighting industry. The problem is that technology OLED for lighting is not yet available on the market, mainly due to the high cost of the devices tested so far.

However, many operators think that the technology costs OLED they could fall shortly, even by 60-70% and facilitate mass adoption in the residential, industrial and tertiary sectors. This is thought to be possible following the example of TV manufacturers a LED (who are experimenting with technology OLED for the production of displays), that is, passing from a production process based on evaporation to production with printing technology ..

The main advantage of technology OLED derives from the potential of the organic material that makes it possible to have a low voltage power supply for the production of light and consequently determine a high luminous efficiency estimated at approximately 60-70 lm / W.

Returning to the limits of technology OLED, another is made up of organic material (i.e. with a predominantly carbon structure) which tends to lose its illuminating capacity in a relatively short time even if it is decidedly good (as for LED) in comparison to fluorescent, metal halide and iodine lighting systems. However, on the lifespan front, ongoing research promises imminent progress.

Technology lighting systems OLED, with good luminous efficiency in terms of lumen per watt lm / W and duration expressed in hours, could allow considerable savings in electricity in various areas. Think of industrial buildings, where the average annual energy consumption for lighting represents 70-75% of the total. But even more so in school buildings where the share of electricity for lighting the rooms is 75-80% of the total. In the residential sector, lighting absorbs 10-15% of the total average consumption of electricity.
