The diploma deals with a research of a new method of fixing a reflector in the lamp housing and its design. The main objective of the diploma thesis is to investigate, which technology is the most appropriate for manufacturing the reflective piece, and how to fix it in the lamp housing in order to lower the cost of the final product. Initially, the thesis describes the technology that could be used to produce the reflective piece, and moves on to the possible solutions for combining the reflective piece with the lamp housing. After determining the wishes and requirements that the product must fulfill, a functional structure was made. With a help of a morphological matrix, six concepts were designed and technically and economically evaluated. Further on, two concepts were processed in more detail and modeled in 3D CAD environment. The final selection, which model is more appropriate is based on the size of the production series.
