Design and optimization of a low beam LED headlamp reflector
Varhaníková, Alžbeta ; Kapusta, Martin (referee) ; Novotný, Jan (advisor)
The diploma thesis deals with the optical design of low beam LED reflector. The thesis aims to optimize the existing low beam LED reflector with an emphasis on achieving a legal and homogeneous light distribution. The theoretical part contains the essay of light sources and optical systems used in headlights, as well as the description of the production technology of LED reflector for different polymeric materials. The experimental part presents a detailed methodology for the optical design of low beam LED reflector in the company software. The thesis also contains a description of the original low beam LED reflector and its problematic parts. The optimization of LED reflector was performed by changing its construction and by the replacement of the light source which increased the robustness of the whole system. In the conclusion, the optimization of LED reflector is evaluated by comparing final light distributions for individual LED reflectors.
Application of Modern Technologies for a Design of Disc Coupling Production
Varhaníková, Alžbeta ; Varhaník, Matúš (referee) ; Sedlák, Josef (advisor)
The bachelor thesis deals with the design of disc coupling and its production by using 3D printing technology. Model of disc coupling and this thesis are supposed to serve as teaching equipment for students at Secondary vocational schools. The theory section contains the essay of shaft couplings with a detailed description of disc coupling, characteristic of individual methods of Rapid Prototyping technology and materials suitable for 3D printing. The experimental section is dedicated to the calculation and construction design of disc coupling and its production using the Fused Deposition Modeling method. The thesis also contains a description of post-production processing and assembly. The attachments of the thesis consist of assembly mechanical drawing and production mechanical drawing of drive disc.
