Study on the development of LED headlamps for used cars

Abstract

Currently, LED headlamps are only attached to newly manufactured vehicles, and it remains difficult to mount LED headlamps on used cars. Therefore LED headlamps need to be developed for used cars as a replacement of their halogen lamps. Due to a number of spatial limitations, it is critical to ensure a certain level of thermal performance. In order to obtain a design for efficient heat radiation, this paper aimed to optimize thermal management through a combination of heat sinks, heat pipes and fans. Based on such a design, this paper succeeded in developing LED headlamps of the desired performance to replace the halogen bulbs of used cars.
