Preface

The present textbook was elaborated on the basis of the extensive experience in the field of vocational training of its authors and is meant for apprentices in electrical engineering.

It deals with elementary knowledge in lighting engineering.

The required knowledge in this field of electrical engineering is presented in didactic form.

Starting from a certain scientific knowledge - which is an absolutely necessary precondition - the learning and understanding of the treated problems is facilitated by many illustrations and diagrams as well as comprehensible texts.

Thanks to the consistent observance of the unity of theory and practice, the apprentices can use the textbook as a working aid in theoretical and practical training as well.

The last part of the textbook consists in tasks and questions for repetition and knowledge tests. They point to the most important contents of training and serve the apprentices for checking their knowledge.

To enable an assessment of the answers given, a key is to be found in chapter 12.
