We aim to propagate scientific research of solid-state lighting. Our activities encompass the investigation, optimization and application of LEDs and their systems for general and specialized lighting. An emphasis is put on LED array and system optimization by varrying the spectral power composition. Our research equipment and software enables us to perform thorough and comprehensive optical, thermal and electrical characterization and optimization for LEDs and other small-sized light systems. In addition to general lighting, we specialize in several specific fields of application, such as greenhouse lighting, medical lighting, and applications of lighting for the control of bacteria and biofilms. Currently the lighting research group is working on several new and ambitious topics.
