Lighting systems in off-grid applications
Lengyel, Ladislav ; Škoda, Jan (referee) ; Baxant, Petr (advisor)
Aim of the master's thesis is at first to explain appropriate light sources and lighting systems; secondly present suitable light sources selection for lighting a small space and design of an off-grid system. The last part consists of an overview about alternative energy transformations to light energy. The first of these three major themes focuses on the analysis of light sources suitable for use in applications with accumulation together with data on energy efficiency and the utilization efficiency associated with them, concentrating on their consumption and possible energy saving lighting within small applications. It ends with a description and calculations of electricity energy indicators for different types of rooms. The second and main part of the thesis is focusing on suitable light sources selection for off-grid systems and impacts on humans and the environment associated with it. An object representing a small application has been created in RELUX® software with suitable light sources installed in it. For this scene, appropriate parts of off-grid systems were selected, which could be used to power the proposed lighting. The last theme consists of a brief about alternative sources, most of which are still in development or existing only at a theoretical level. All of these alternative sources are having a possible application in the future.

Lighting and lighting systems for stand-alone applications
Čejka, Lukáš ; Škoda, Jan (referee) ; Baxant, Petr (advisor)
This bachelor's thesis deals with the issue of lighting systems for stand-alone applications. These systems are independent of the electrical connection and they are powered by batteries. Batteries are charged by independent sources. The work is more focused on an autonomous lighting system that uses a solar panel. It mentions the main components of the system. Furthermore, in this work, we can find types of stand-alone lighting applications, their possibilities, problems, advantages and disadvantages, economic balance and also outline other possible solutions.

Design of the lighting system in the joinery workshop
Ševčík, Přemysl ; Novák, Filip (referee) ; Škoda, Jan (advisor)
The bachelor thesis deals with evaluation of current lighting system in workshop and creation a new model of lighting system. In the theoretical part, the thesis deals with lighting parameters of lighting system. Practical part is dedicated to evaluation of current lighting system that is based on performed measurement. Further the new model of lighting system is created so that the work in workshop would be pleasant and economical. An economical proposal is created for the new lighting, which is compared with the current lighting system.

Design of a reference luminaire
Cikryt, Adam ; Baxant, Petr (referee) ; Škoda, Jan (advisor)
The master's thesis deals with the design and manufacturing of a reference luminaire for use in lighting laboratories. In the design of the luminaire, simulations in Ansys Speos are used to assess the luminaire's lighting properties. The designed luminaire is manufactured using 3D printing and assembled. The light technical properties of the luminaire are determined by measurements in lighting laboratories.

Design of the calibration box
Šácha, Tomáš ; Motyčka, Martin (referee) ; Škoda, Jan (advisor)
The diploma thesis deals with the description of basic photometric quantities, light sources and their parameters. The work also describes the LumiDISP luminance analyzer, for which the calibration box is designed. The next part of the diploma thesis deals with the design of the calibration box in the Inventor program and later the simulation of the calibration box in the Ansys Speos program. The simulations in Ansys Speos led to the determination of the number of light sources in the calibration box, which were then used for production. The work also describes the procedures and partial parts of the design and production of the calibration box, including its revitalization and testing.

Measurement of directional non-uniformity of the correlated color temperature of LED luminaires for road lighting
Růžička, Josef ; Škoda, Jan (referee) ; Motyčka, Martin (advisor)
This master's thesis deals with the topic of correlated color temperature measurements. There has been an increase in the demand for accurate correlated color temperature measurements due to regulations concerning reconstruction of the street lighting made by Department of Industry and Business. The main objective of this work is to determine which measuring devices and methods would make correlated color temperature measurements to be done in the most accurate and practical way. The evaluation is based on five laboratory measurements and two outdoor measurements. The main subject of these measurements is biodynamic LED lamp Tungsram SLBt. A verification of certain output data as well as simulating situations that would be too difficult to measure is made by an algorithm created in Matlab software. Final part of the thesis deals with the accuracy differences among various correlated color temperature measuring methods. It describes advantages and disadvantages of these methods and proposes ideas for consequent inquiry. This thesis finds its use in correlated color temperature measurement error and uncertainty discoveries that will have to be dealt with in the future. Also, theoretical part of the thesis may be used as lighting technics learning material.

Lighting design of production hall
Pavlinský, Branislav ; Novák, Filip (referee) ; Škoda, Jan (advisor)
Nowadays, a large number of people spend a lot of time in the presence of artificial lighting and therefore artificial lighting and the correct design of such lighting is very important. This work deals with the evaluation of the original state of the lighting system of the production hall and the design of a new lighting system. Lighting design is solved using the RELUX program. Luminaires from the Czech manufacturer TREVOS were used to design the lighting.
