L’éclairage DEL : Évolution ou Révolution?
5000 ans av. J.-C., les mouches à feu étaient capturées, mises dans de petits bocaux et utilisées en tant que lampe. 3000 ans av. J.-C., des chandelles faites d’huile végétale et de cire d’abeille étaient utilisées en Chine. En 1801, Sir Joseph Swan, au côté de Thomas Edison, inventa la première ampoule incandescente…
LED Lighting — Evolution or Revolution
In 5000 BC, fireflies were captured and enclosed in a small jar and used as a lamp. In 300 BC, candles made of plant oil and beeswax were first used in China. In 1801, the incandescent bulb was invented by Sir Joseph Swan, alongside Thomas Edison. Together they formed the Edison & Swan United Electric Company and gave the World its first mass produced light bulb…

In-depth Assessment of OLED Display Quality
Organic LEDs (OLEDs) are an interesting and promising new display technology. They provide a number of major technology enhancements for displays and televisions, such as high contrast ratio, wide viewing angle, and very fast response time.
The Evolution of OLED Technology for Lighting
Although a relatively new technology, organic light-emitting diodes, OLEDs, are labelled today’s most promising display technology. As its name suggests, OLED is an advancement upon LED or light-emitting diode that allows for even thinner and brighter displays…
Tunable White Will Be The Lighting Game Changer of 2015
LED keeps evolving. Six or seven years ago no one thought that LED was bright enough or cost-effective enough for general purpose lighting. Then efficacies improved, colour got more consistent, costs came down, and nowspecifiers and end-users want LED first, everything else as a second option. LED has arrived and there’s really no questioning it now.
