Headlamps from various light sources, including halogen, high-intensity discharge (HID), light-emitting diodes (LEDs), and lasers, are emerging as headlamps play the most important role in automobile safety. However, the lamps used in automobile headlamps pose different problems that affect the light transmittance of the headlamp due to radiant heat. The purpose of this study is to predict the effect of such light sources on light transmittance by conducting an experiment and measuring the radiant heat characteristics of each light source used in automobile headlamps under a low-temperature environment.
