Hodnocení kvality osvětlení s využitím moderních softwarových prostředků / Evaluation of Lighting Quality Using Modern Software Tools

Fazekas, Tibor January 2011 (has links)
This thesis deals with the evaluation of the quality of lighting with the usage of the latest software products used nowadays. The first part of the work is about indoor lighting, the basic requirements invested in lighting, and the basic concepts of indoor lighting. The second part includes complete search for today's computer implements for projecting, simulating, calculation and analysis of light, their functions and characteristics, including luminance analyzers based on CCD sensors and their software equipment. The last part of the work has the task to model a computer room using softwares which can be found within the territory of VUT Brno, and the task was to assess its lighting. Following this, with the help of luminance analyzer, the task is to capture the scene under different lighting conditions and to evaluate the measured data.

Moderní systémy pro řízení osvětlení / Modern systems for lighting control

Klein, Tomáš January 2012 (has links)
This Master's thesis deals with intelligent installation systems, focused on lighting systems using the DALI bus system. Theoretical part of this work includes a list of currently available intelligent installation systems and its use in both households and industrial buildings. A summarizing description of KNX and DALI bus systems and their actuators and actuating units are a part of this paper. The practical part proposes two examplary boards designed for laboratories of UEEN VUT in Brno and describes its construction, as well as the programs necessary for its programming, control and monitoring. The outcome of this Master's thesis is a survey of possible remote control of DALI bus system's actuators and mutual compatibility of KNX and DALI bus systems. Furthermore, this paper includes background material for laboratory task, based on data found about remote control and DALI bus system's monitoring.

Simulační model veřejného osvětlení pro Network Simlator 3 / Simulation model of public light for Network Simulator 3

Kapoun, Vladislav January 2015 (has links)
This thesis is focused on the smart public lighting management possibilities. It describes smart public lighting management itself and the advantages of the new management possibilities compared to the current ones are illustrated as well. Furthermore, it deals with a comparison of the most used light resources and LED light resources. This thesis also outlines NS-3 simulation environment and states its advantages. Theoretical concept for energy-saving smart public lighting management system and its modifications for the needs of simulation is described in the paper. This theoretical concept is simulated and compared with the current smart public lighting management systems as well as with the systems designated by the third party.

Simulace LED náhrad v reálných podmínkách / Simulation of LED retrofits under operational conditions

Tomeš, Martin January 2014 (has links)
This Master’s Thesis on Simulation of LED retrofits under operational conditions is divided into theoretical and practical part. Theoretical part in the introductory section deals with the concepts of lighting technology and presents some electric light sources, such as classic bulbs, halogen bulbs, linear and compact fluorescent lamps. It also describes the principle of electroluminescent light sources (LED), which discusses principles of yielding a white light, the main advantages of LED etc. The reader is familiar with the issue of compensation the linear fluorescent lamps tubular LED source and with the work environment programme ReluxPro that is used for design of the lighting system. Practical part of the thesis is divided into two chapters. In the first chapter, measured linear fluorescent lamps and LED modules for the light-technical parameters, luminous intensity, radiation spectrum and settling time of light sources are evaluated and compared. The second chapter is solved by using ReluxPro, which explores the impact on the lighting and the brightness of the room layout SA 5.10 while using various light sources. In conclusion, there is an economic aspect of linear fluorescent lamps and LED modules analyzed. Results from the program ReluxPro are continuously compared with real measured values.

Možnosti osvětlení vozidel pro zvýšení bezpečnosti silničního provozu / Possibilities of Vehicle Lighting to Increase Road Transport Safety

Balharová, Gabriela January 2012 (has links)
This master’s thesis deals with the possibilities of illumination of motor vehicles. Thesis is divided into two sections, from which the first discusses precisely the possibilities of lighting of motor vehicles at the present time. What are the modern lighting techniques, that can be found on the market and what is their impact on safety enhancement in road traffic. Second section is about the practical measurement of low and high beam afterglow. This measurement is being compared between two types of headlamps, namely halogen headlights and xenon headlights. Part of the measurement is as well measurement of illumination intensity precisely for these headlights. The output of measurement is the creation of own illumination intensity diagrams and afterglow diagrams of particular headlights, in comparison to isolux diagrams provided by the headlights manufacturer. Consequently are solved the issues about utilization of the isolux diagrams in expert praxis.

Raytracing virtuálních grafických scén / Raytracing of Virtual Graphics Scenes

Rypák, Andrej January 2012 (has links)
This thesis is dedicated to ray tracing based rendering methods, primarily the original ray tracing. Besides introducing a brief historical overview of algorithms from the family, it presents all the essential tools, techniques and physics needed for designing a rendering application in detail. A significant part of the document consists of an implementation of a photorealistic rendering application for interactive graphics 3D virtual scenes. The focus is on rendering without using any additional model information. The thesis includes descriptions and explanations of specific problems and their solutions.
