FEKT-LSVTAcad. year: 2019/2020
The course deals with the basics of lighting technology. Photometric and radiant variables and their interrelationships are explained, the spectrum of optical radiation properties of eye system and vision, color measurement and color rendering index. Next the principles of light generation, the main types of light sources are explained. Principles are explained in detail and construction of incandescent light sources, linear and compact fluorescent lamps, sodium lamps, mercury vapor lamp, metal halide and LED sources. Next the main features of the other light sources, such as induction lamps, xenon lamps and sulfur lamps are explained.
Learning outcomes of the course unit
Graduate of this course is able to:
- Describe the basic physics of light,
- Explain the principles of light generation,
- Explain the nature of vision and the visual system functions,
