Course detail

Lighting Technology

FEKT-MKC-SVTAcad. year: 2024/2025

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.

Entry knowledge

The student who select the subject should be able to explain the basic laws of electric circuits, should have knowledge of basic electrical quantities measurements. General knowledge is required at the level of bachelor's degree, but it is advisable to have completed a course Energy use (BUEE).

Rules for evaluation and completion of the course

up to 24 points per laboratory protocols
up to 16 points for the progress tests of knowledge
up to 60 points for the final exam, which is focused on an overview of issues. The exam is form of a test on a computer with an oral supplement in the event of deficiencies.
Laboratory teaching of the course is compulsory, properly excused absences can be arranged with the teacher, usually replace to last week or the following week, unless the teaching is divided into multiple groups.
