LED and laser diode based illumination systems with a tuneable radiation pattern KU Leuven
The adoption of solid-state light sources for general lighting applications was mainly driven by the continuous need for efficiency improvements in the lighting industry. Most luminaires nowadays, make use of LEDs that can be easily dimmed if necessary. Introducing inexpensive sensors into these lighting fixtures can further reduce energy consumption by monitoring the environment and adjusting the illumination accordingly. A simple example ...
