This section contains information and supporting materials for laboratory assignments in lighting technology courses.
FRVS Project Assignments - Innovation of Teaching in the Lighting Laboratory
Principal investigator: Ing. Jan Skoda Co-investigators: Doc. Ing. Petr Baxant, Ph.D.; Ing. Tomas Pavelka
The project innovated the courses Lighting Technology and Lighting Systems. A new modern workplace was created and ten laboratory assignments were prepared to expand practical knowledge and skills in the field of lighting technology and small light sources, especially LEDs.
These assignments were created within grant project no. 3089 of the Higher Education Development Fund in 2010.

FRVS Project Assignments - Innovation of Laboratory Teaching in the Lighting Laboratory
Principal investigator: Ing. Tomas Pavelka Co-investigators: Doc. Ing. Petr Baxant, Ph.D.; Ing. Jan Varmuza
The project focused on innovation of laboratory teaching in the courses Lighting Technology and Lighting Systems. Its output was a workplace for measurements in lighting systems using a wireless data acquisition system. Seven new laboratory assignments were prepared so that students could verify their theoretical knowledge through independent measurements.
These assignments were created within grant project no. 3215/2011/G1 of the Higher Education Development Fund in 2011.
Assignment List
- Evaluation of light source parameters
- Influence of daylight on a lighting system
- Evaluation of a lighting system as a whole
- Choice of luminaires with respect to their placement
- Programming an application for monitoring a lighting system
- Evaluation of measured data using DARCA software
- Selection of suitable light sources for specific lighting applications
Lighting Technology (MSVT, LSVT), Academic Year 2011/12
