Original Abstract

Over the last decade lamps became a design feature of a car body and to preserve their primary purpose they are much more complex than in the past. Today’s car lamps contain powerful light sources, which utilize new technologies such as dot-concentrated light (LED chips or xenon discharge tubes). One of the unfavourable properties of these products is a high amount of thermal energy produced in a small area, causing a high thermal stress on the components. For this reason, it is important to know the temperature in critical locations to avoid damaging the lamp body or causing a defect in the light source itself. This paper presents the results of a numerical simulation of the working conditions of a lamp, the measurement inside the environmental-simulation chamber with a real lamp, providing the same conditions and the verification of the simulation results with the measurement, which confirmed the precision of the numerical simulation. The verification procedure was developed at the Heat Transfer and Fluid Flow Laboratory of the BUT in partnership with Skoda Auto a.s.
