Course detail

Lighting Technology

FSI-HLT-KAcad. year: 2022/2023

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.
