The lighting map in GIS
Nejedlý, Lukáš ; Potočňák, Tomáš (referee) ; Rozman, Jiří (advisor)
Bachelor thesis deals with the lighting of roads and public areas. The work is divided into two parts. First part is focused on the basic terms of lighting technology, measurement methodology and appropriate hygiene standards. The paper also discussed electric light sources used in public lighting and basic information on the geographic information system ArcGIS, which was used during the processing of the measured values. The second part is focused on the measurement of illuminance in Žďár nad Sázavou and graphical analysis of the measured values in ArcView GIS. The measured values of the illumination were compared with hygenic limits standard ČSN 13 201.

Street Lighting Control
Kořenek, Jan ; Krbal, Michal (referee) ; Štěpánek, Jaroslav (advisor)
This bachelor thesis deals in a theoretical part with the origin of the light, his features and lighttechnical quantities. There are also characterized light sources, which are currently most used to control street lighting. There are further described basics of the street light and currently most used ways of street lighting control. Further part of this thesis is focused on practical control of different types of light sources and monitoring their parameters, such as luminous flux, power, efficiency or correlated colour temperature during voltage reduction. These light sources are high pressure sodium lamps, halogenid lamp, fluorescent lamp and high pressure mercury lamp. Main conclusion from measurements are several cross characteristics, where is possible to monitor behavior of the parameters during voltage reduction. The last part concerned about practical street lighting control in Bezděkov, which is a village located near Havlíčkův Brod. There was connected the dimmer. On the street was created net of points according to the standard. In these points were measured illuminance for voltage 230 V and then for lower voltages 210 V and 190 V. These values were processed and average and minimum value was compared with the value defined in the standard.

Map of lighting in GIS
Suchý, Petr ; Rozman, Jiří (referee) ; Čech, Petr (advisor)
This thesis deals with legislation and public lighting. Furthermore, this topic is closely related to describing the characteristics of lighting and hygiene levels in comparison with the IEC standards. The work focuses on theoretical training, follow-field measurement and analysis of data obtained. The paper discussed aspects related to the light, physiology of vision and optical comfort. Outdoor lighting and its technical characteristics. Brief description of standards and their use in planning practical measurement of public lighting. A substantial part of the work is focused on graphical analysis of values and their comparison with the standard.

Design of street lamp
Fridrichová, Eva ; Rubínová, Dana (referee) ; Zvonek, Miroslav (advisor)
My bachelor´s work discuss about a lamp of street lighting. This work consist of historic, technical and present design analyses. As a reset is design, which fulfil fiction, safety and modern look. Work consist of text part, visualizations, poster and model of lamp.

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.

Automatická adaptace pouličního osvětlení na základě dat z kamer
Švanda, Jan
The thesis deals with the creation of a system that, based on the analysis of the real situation on the road using image data from cameras can provide data for the prediction of the optimal lighting settings for each moment. The thesis also deals with the selection and comparison of detection methods and subsequent optimization of the selected method.
