Modern Systems of Vehicle Lighting
Špaček, Ladislav ; Huzlík, Rostislav (referee) ; Hájek, Vítězslav (advisor)
A vehicle lighting is a basic component of active safeness, which, as an integral part of any vehicle, contributes to road traffic safety increase. From the very beginning, the car electrotechnincs has been engaged in the car lighting and visibility improvment for worse driving conditions, e.g. fog, rain, night ride etc. Thanks to new car lighting systems, such as adaptive headlights, LED based light sources and night vision systems, road traffic became much safer than ever before.

Control of headlight assembly line
Sikora, Martin ; Hynčica, Ondřej (referee) ; Štohl, Radek (advisor)
This thesis deals with design of the reflector assembly line. The document contains the analysis of the customer requirements sheet. In short there is written how to put the parts of the reflector together. The Poka-Yoke method is properly described in this work too. This method is used to design of the actions, which are trying to decrease the risk level of wrong reflector composition as low as it is possible. FMEA and PFMEA methods are explained in theory. There is the plan how to make the analysis too. The instrumentation of one part of the line is designed according to this analysis and according to the customer requirements. The OEE pointer is used to test the right effect of the Poka-Yoke method. The next aim of this thesis is to compare chosen PLCs for control of the assembly line and to choose one of them. On the base of the analysis there is designed the control program in the flowcharts form. One part of this thesis is focused on design of the visualization for the chosen operational panel.

Lighting systems of vehicle
Žlebek, Michal ; Guzej, Michal (referee) ; Štětina, Josef (advisor)
The aim of this work is to explore the development of headlamps and focus on the problem of cooling. The first part is devoted to automotive lighting and to headlamps generally. It deals with history, manufactures, functions and basic construction of headlamps. The next section describes the types of headlamp and the procedure for its construction depending on used light source. In semifinal part can be found explanation of heat origin in LED and with the help of heat transfer is described its spreading. At the end is this work dealing with problems of cooling when using LEDs. It shows view of cooler and explaining how important is to use simulations during heat spreading counting.

Proposal of the Plastic Overload Clutch
Ujčík, Martin ; Mrázek, Dušan (referee) ; Samek, František (advisor)
The bachelor thesis describes the proposal of the geometrical change on the sliding holder which is ensuring adjusting of the headlamp in to the correct position. It means a change of geometrical concept. Proposed geometry overtakes the security function of the overload clutch witch ensured in current solution additional part. Proposal was created in CAD System Catia. Function of the solution was tested with finite element method in SimDesigner program and with the evaluation of measuring of prototype part.

A New Design for Sealing Headlamp Adjusting Screws
Lysa, Bohuslav ; Mrázek, Dušan (referee) ; Samek, František (advisor)
The bachelor thesis covers several issues connected with the sealing of headlamp adjusting screw. The thesis includes analysis of the O-ring fastening and analysis of the fixation adjusting screw in functional position. On the basis of the analyses a new design of O-ring fastening, a new design of the adjusting screw fixation are proposed. Finite Elements Method in SimDesigner software using 3D modeling capabilities provided by Catia V5 were used for calculations and simulations in selected parts of the analysis. The feasibility study regarding adjustments of the existing casting form of the adjusting screw is included in the thesis.
