Research

Light source characterisation and design

Development of methods for the photometric, spectrometric and colorimetric characterization of light sources

Any kind of light.

Single lamps or LEDs, complex lighting systems, such as multi-LED systems, monitors, displays

Methods

Development of innovative methods for the photometric, spectrometric and colorimetric characterization of light sources

Conditions

Efficiency analysis under abnormal or deformed power supply conditions

Colour rendering

Colorimetry applied to the study of light sources for the illumination of works of art

Light pollution

Analysis of the outdoor artificial light at night and its effect on the environment

Reflectometry

The Laboratory uses a goniometric system for the analysis of samples of surfaces: retroreflectors, paints, road pavings.

Any kind of surfaces

The design of a street lighting is based on the knowledge of the reflection properties of the road pavings. Their direct measurement allows the realization of better designs and a significant energy saving in road lighting.

Road lightingE

External measurements for the assessment of the performances of a road lighting system. Novel methods of road lighting and signalling are under study, they will allow an important energy saving.

Colorimetry of cultural heritage

The use of different lights can modify the appearance of a work of art; a clever analysis can allow to obtain the best results of perception. The Laboratory is able of evaluating the risk caused by the lighting, with the aim of preserving the object and providing the optimal exposition.
