The Green Light Source

lumiweb_green_light_source1_410x450You Matter. Light Matters.

Light – an important and indispensable part of life.

Light affects our mood, improves our well-being and enables us to experience and achieve more.

No wonder, that a large part of the electrical energy produced today is used for lighting. And the figures are dramatic.

Worldwide almost 20 percent of the electricity is used for lighting. At the same time the energy for lighting accounts for six percent of the world’s greenhouse gases. This is about 1.9 billion tons of carbon dioxide (CO2) or about 70 percent of emissions from all passenger cars worldwide (Source: United Nations Environment Program). By using energy-saving lighting – such as OLEDs – these figures can be reduced significantly. The UN is even talking of halving them.

Although OLEDs are still a relatively new lighting technology, they already show today, that they will be far superior to conventional lighting systems in terms of efficiency and power consumption. They follow LEDs in setting new standards in this area.

Not only green because of efficiency

Efficiency and longevity

OLEDWorks Lumiblade OLEDs last over 30 times longer than inefficient incandescent light bulbs. Tests have shown that OLEDs will become about as efficient as LEDs already are. These provide up to 80 percent better efficiency. So the energy savings with OLEDs compared to the traditional light bulb are obvious. In addition, the manufacturing process of this new light source is very effi cient as well, making the OLED a true all-rounder when it comes to effiency.


OLEDs consist of almost 100 percent glass. Therefore they can easily be recycled at the end of their operating life. Lumiblade OLEDs also meet the European Union’s stringent RoHS and REACH directives. With OLEDs, users do not only get a very attractive surface light source, but also a particularly green one. An increasing number of lighting solutions in which OLEDs are used are coming onto the market in the near future. With each of these solutions users ensure a reduction in their electricity bills. And a reduction in global energy consumption for lighting.

Light output

OLEDs are surface light sources, making a diffuser screen which scatters the light unnecessary. This has a big advantage because with conventional light sources up to 70 percent of the light output is lost by the system. Not with OLEDs. Here the efficiency of the light source equals the system efficiency.
