Abstract:
With increasing demands for more light efficiency and longer lifetime, all
automotive lamps must be physically tested to evaluate both illumination and thermal quality.
However, due to an excessive heat from a more powerful light source and modern complex
design plastic lamps, a severe thermal degradation can be occurred on thermoplastic parts of
those automotive lamps. Hence, this paper proposes an application of ray tracing method to
examine the beam quality and predict the thermal degradation area on a small automotive lamp
in the early design stage. First, by applying ray tracing method, both illuminance and lux
distribution on a small automotive lamp were calculated in order to examine its beam quality.
Next, the energy concentration on lux distribution was presented to predict the possible thermal
degradation area on lamp components and then compared with thermal distribution results
obtained from finite element Monte Carlo radiation analysis. Finally, the thermal degradation
area forecasted from lux concentration were validated with temperature measurement of a lamp
prototype. In this study, the ray tracing simulation results show that the lux concentration
regions are prone to the thermal failure area on the lamp. Consequently, this method can be
used as a speculative tool not only to precedent assess the illumination and thermal quality of
lamps, but also reduce the cost and time-to-market for automotive lamp manufacturing as well.
