Control of Pixel Front Lighting
Kostelník, Pavel ; Vochyán, Josef (referee) ; Dřínovský, Jiří (advisor)
This master’s thesis presents new tendency in automotive lighting – matrix LED headlamp. This thesis consists of description of matrix headlamp construction, main functions of matrix headlamp and controlling by using new integrated circuit, developed by ON Semiconductor Company. The aim of this project is concept of algorithm, which provides correct function of integrated circuit. A part of this thesis is to develop and assembly evaluation kit with this integrated circuit, which will be use to present integrated circuit for customers.

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.

New Solutions for Settings Car Headlamps
Glatter, Willi ; Straka, Ivo (referee) ; Kalivoda, Milan (advisor)
The aim is to develop new adjusting element. There were three versions of engineering design suggested, which were consequently simulated for various materials. Optimal material was chosen and came up to production suggested variants. These variants were consequently implemented to the headlamp and were consequently measured and tested. During measuring was under consideration change of CutOff line position after heat imunity and vibration tests. Result is selection only one material and only one engineering design of adjusting element solution, which warrants easy and fast assembly and confidential adjusting of reflector, for standardization and implementation to recently develop headlamps.

Draft measures to reduce customer complaints
Charvátová, Petra ; Strnad, Vlastimil (referee) ; Tyráček,, Petr (advisor)
This diploma thesis deals with customer complaints of headlamps in Automotive Lighting s.r.o. The goal is to analyze the state of customer complaints for 2018 and to evaluate the biggest source of nonconformities in terms of the type of complaint based on Pareto analysis. The thesis focuses on solution of one particular type of complaint. The key part of the thesis is also the processing of the process analysis, the evaluation of the causes of the complaint and the draft of corrective measures that would eliminate the problem. The conclusion of the thesis contains evaluation of the proposed corrective measures, including from the economic point of view.

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.

Verification Tightness of Headlamp
Maule, Jiří ; Pernikář, Jiří (referee) ; Osička, Karel (advisor)
The task of my work is to describe and analyse tightness control of front headlights in automotive industry. This work is concerned with theoretical indi-cative allocation according to the light source, development and contruction of headlights in preamble. There is shown the way of disclosing the outflow pres-sure area at loose headlight in next part of this work. It defines the most proba-bly caused reason of untightness with help of Ishikawov diagram. There is also made evaluation of measured values and determined the main cause of un-tightness. At the end there are shown possibilities of statistic´s evaluation of measured values and made changes necesarry for untightness elimination.

Analysis of the effect of damping on the magnitude of the response during dynamic headlamp excitation
Lukáš, Jan ; Biskup, Martin (referee) ; Vosynek, Petr (advisor)
The aim of the submitted diploma thesis is the magnitude determination of the headlamp response to the dynamic excitation. Currently it is necessary to measure this response, because it is one of the assessed criteria of quality of the headlamp. When comparing results of the experimental measurement and the computational modelling, a good consensus of resonant frequencies is observed, but there are significant differences in acceleration amplitudes. The cause of this is the variable damping value. The theoretical part of the thesis deals with polymeric materials, basics of oscillation and damping. It serves to understand the mechanisms, which influence the results of the experimental measurement. The practical part is dedicated to the procedure of the computational modelling and the experimental measurement implementation. The analysis of the experimental measurement results leads to an ascertainment of nonlinearities, which influence the headlamp behaviour. The results of a sensitivity analysis of the computational modelling are used to create curves, on the basis of which the damping is estimated. The inclusion of the estimated damping into computational modelling leads to reduction of the compared differences of the acceleration amplitudes. The conclusion of the thesis contains the recommendation for the damping determination during the computational modelling of the headlamp.

Design of the car headlight
Struhár, Slavomír ; Bukvald, Jiří (referee) ; Buganská, Tamara (advisor)
The topic of this bachelor's thesis is design of headlamp for a further unspecified automobile. The first part of the thesis is formed by Overview of current knowledge dedicated to the history, the present and the near future of headlamps of series-production cars. The following sections describe the objectives of the thesis, the process of the design itself and present the final design of the headlamp. The final part evaluates the results of the work with respect to the stated objectives.
