More efficient lighting with LEDs

LEDs (light-emitting diodes) are meanwhile a ubiquitous light source. They offer higher luminous efficiency paired with lower energy consumption, come in a wide range of colors, and enable new design options due to their small size. But all of these advantages only come to the fore when the light fixtures are adjusted to the LED technology. Evonik Industries AG developed PLEXIGLAS LED for precisely this purpose. It can be used to produce crystal-clear, structured or light-diffusing lighting covers. Evonik Industries AG is presenting these possibilities at the International Trade Fair for Plastics and Rubber, K 2013, in Hall 6, Booth No. B28.
PLEXIGLAS LED guides light efficiently to the point where it is needed. Lighting applications serve different purposes. Street lights are designed to light up the street, not the space around the light source several meters up in the air. For this, light fixture manufacturers use covers that guide the light through fine structures in the material.
In other types of lighting, though, light needs to be diffused in order to distribute brightness uniformly throughout the room. PLEXIGLAS LED was optimized for this purpose. It contains special embedded diffuser particles, which ensure that the light fed in via the edges is evenly emitted across the surface. This edge lighting enables slimmer structures and requires smaller fitting depths, as in the panel lights that are becoming more and more popular. These are ultra-flat light fixtures that can be installed directly in the ceiling as recessed lights.
