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.

Active cooling of the car headlight
Žlebek, Jan ; Mauder, Tomáš (referee) ; Štětina, Josef (advisor)
The main goal of this bachelor thesis is to design the cooling of the headlamp by using a Peltier module. The first chapter is to acquaint the reader with the possibility of heat transfer. Further work is focused on various types of heatsinks and printed circuit board. The third part describes the principle of functions of Peltier's module. The last part of the work contains the design of the heatsink assembly and the design solution of fixing the cooling assembly in the housing.

Optimization of wall thickness for headlamp body
Prokeš, Radim ; Tomaj, Martin (referee) ; Kandus, Bohumil (advisor)
This project is concerned with the issue of the thickness optimalization of the wall thickness of the plascics headlamp housing by the simulation Moldflow analyse. There are mentioned the basic information about the plastic materials and their dividing over there. Furthermore the description of the injection process, the injection machines and the tools is included. The principles of the proposal and the construction of the plastics part is also mentioned here. In the application of the Moldflow Plastics Insight 6.0 there is provided the simulation of the melt moldflow for the proposed headlamp housing. Based on this analyse the proposal of the thickness reduction of the wall thickness of the headlamp housing is worked out with the aspect on the required qualities. It also contains the technoeconomic estimation of the benefit optimalization.
