Visionary seminar: A new Age of Enlightenment - Solid State Lighting
Dramatic changes are unfolding in lighting technology. Lighting applications that use light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs), or polymer light-emitting diodes (PLED) are commonly referred to as solid-state lighting. Solid-state lighting is the first truly new lighting technology to emerge for nearly 100 years. A semiconducting material converts electricity into light. Light-emitting diodes, or LEDs, have been around for more than 30 years, but until recently they were used only in small electronic devices as indicator lamps. Indeed, only since about one decade the efficiency of solid-state light emitters to convert electricity into light has surpassed the performance of incandescent light bulbs.
Today, solid-state lighting is increasingly used in applications such as red rear-lights of cars and traffic lights, because it offers design flexibility, cost savings, energy savings and a very long lifetime. In the near future, solid-state white light sources will be used for applications such as as headlights for cars and general-purpose illumination for the office and the home. In addition, the organic light-emitting diode technology will propose a near-infinite freedom of form and color to the lighting designer. Large-area illumination tiles will be integrated in ceilings or into mirrors that reflect light in daylight but emit light at dusk, flexible illumination foils will be bent around pillars or hung on the wall. The color palette will include not only the saturated colors such as blue, yellow or red, but also unsaturated colors such as pink, pale yellow, ... The user will be able to tune the color of his illumination panel, according to his needs or mood. Last but not least, these technologies will allow considerable energy savings in public and private life.
The program of the evening will highlight the opportunities that will be offered by solid-state lighting in the coming decade, but also explain the immense challenges that still lie ahead before these technologies will make their break through.
