Power line data transfer
Ryška, Aleš ; Janík, Lukáš (referee) ; Dobesch, Aleš (advisor)
This thesis deals with powerline communication and application its use in headlamp. In thesis are compared various commercial available solutions, especially the Qualcomm QCA7000 modem. Furthermore, the work deals with the design and the prototype for exploring the applicability of the existing wiring in automobile. The aim of the thesis is to construct a prototype that allows the communication with the front lamp of the car via the power line.

High resolution digital light source design for automotive industry
Machač, Petr ; Rubeš, Ondřej (referee) ; Věchet, Stanislav (advisor)
Digital high definition light sources are a new way of communication between car and other road users. By intelligent switching of high beam or projection of various warning or information symbols on the road a lot of even tragic traffic accidents can be prevented. The purpose of this thesis is to explore contemporary automotive lighting technologies, then to choose the appropriate technology for high definition light source and design a prototype of mechatronic lighting systém.

Tool for measurement goniophotometer
Poledník, Radim ; Klapka, Milan (referee) ; Dvořáček, Jiří (advisor)
The aim of the bachelor’s thesis is to develop a new multipurpose storage for photometric measurement of automotive headlamps and rear lamps. The goal of this device is reduce overall time required to measure samples, mainly rear lamps. The concept takes into account qualitative and quantitative requirements. For example, the effective shielding of light and heat radiation, constant electrical quantities, and easy manipulation in difficult condition of the photometric test halls.

Placement Optimization of Projector Lens
Bezděk, Matěj ; Važík, Jiří (referee) ; Novotný, Pavel (advisor)
This diploma thesis deals with the creation of engineering design of holder of projector lens. The thesis is created in cooperation with department of development in Varroc Lighting Systems, s.r.o. Initial part provides a brief description of the development of lighting technology used in car´s headlamps. The following part describes solutions currently used in clamping the lens in holder. The main part of the thesis focuses on the design of holder of projector lens itself. Projector lenses testing provide critical values of cohesive failure of the lens material, which cannot be exceed during the process of lens fitting and its subsequent clamping. In the final part the engineering design is verified and optimized using finite element analysis.

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.

Optimization of technological parameters of injection plastic parts
Hamáček, Richard ; Hlaváček, Martin (referee) ; Kandus, Bohumil (advisor)
This project is dealt with optimalization of moulding procedure of plastic housing of headlamp for project DCW 204 Mopf halogen. The aim is reach a shorter injection moulding cycle time with keeping of claim quality of plastic part. Optimalization will be done based on modification of moulding pressing time. We observe warpage in axis X in the most problematical points of housing by using of contactless measuring optical technologie ATOS III Triple Scan. Simulation analysis for injection moulding was used for prediction of housing warpage up to unforming in every chosen moulding pressing time. According to reaching data in this way comparison of predicted warpage was able to done up to unforming time and real warpage of housing after unforming. According to reaching data in a different period of time warpage of housing during time flowing was observed.

Replacement of headlamp parts screw fixation by a plastic nail
Lysa, Bohuslav ; Píška, Miroslav (referee) ; Polzer, Aleš (advisor)
The master thesis covers several issues linked to a substitution of headlamp screw fixation by a plastic nail. The thesis includes an analysis of the headlamp technology, including description of the prescribed durability tests. On the basis of the analysis some new designs of plastic nails are proposed, consistent with characteristics of plastic materials. Selected outcomes of the analysis have been tested as prototypes and verified with Finite Elements Method in SimDesigner including 3D modeling capabilities provided by the Catia V5. The feasibility study regarding a casting form of the new design of plastic nails and technical economic valuation for contingent assembly mounting is included in the thesis.
