Course detail

Optics and Electronics in the Automotive Industry

FSI-HOEAcad. year: 2018/2019

The course is a practical continuation of the compulsory course Optoelectronics. The course extends the knowledge of the optical part of the headlights of automobiles and includes the process from the legislative background of the design of headlights to practical examples of optical surfaces simulations. The students will deal with technical solutions of unusually thick-walled moulded optical lenses from plastic materials. Another section is devoted to the LED technologies used in headlights. Some practical proposals for the application of power LED chips and their application in assemblies consisting of three directions (reflective, project and matrix systems) are included. The electronics part is connected with practical demonstrations of samples, management and control systems, and discusses the possibilities of laser LED applications. That includes a look at the technology of assembly lines for LED systems and optical systems, their characteristics and risks associated with serial production, and it covers also the production costs of the assemblies and facilities.

Aims

Broadening the knowledge of optics and electronics in the practical application for the power LED headlight systems used in cars. A technical specification of the product approval process is included, according to the industrial property laws. The light sources and functioning of various types of optical systems and the latest trends in automotive headlights are described. In the practical part, students are trained in the optical simulations and how to evaluate the results of the simulation. Student will become familiar with the latest trends in the exterior automotive lighting. The optical part will be followed by the electronics use, such as the modern LED technologies. The modern trends in the industry field and visions are highlighted. Student gets an overview of the principles and characteristics of LEDs, means of their power, temperature parameters and ratios for LED modules as well as advanced lighting control systems in the car. The student will be familiar with the problems of producing LED modules also representing the complex group of LED chips and optical units.

Specification of controlled education, way of implementation and compensation for absences

All of exercise lesson are obligatory. The student’s own work and knowledge is assessed in practicals. According to the studied topic some lessons will be practicals - carried out in the lab, and some will be focused on the theory - calculations carried out in the classroom in a seminar form. Absence from seminars should be substituted for by attending a seminar with another study group or individually by the agreement with the teacher. Lessons may be occasionally inspected by the head of the department.
