Development of a heat dissipating LED headlamp with silicone lens to replace halogen bulbs in used cars

摘要

LED headlights have been developed for newly produced automobiles, but LED substitutes to replace halogen headlamps in used and second-hand automobiles are nonexistent. Hence, this study developed a high efficiency LED headlight that can act as a replacement for halogen bulbs. To achieve this, a silicone lens capable of producing a light distribution curve identical to halogen, and an LED with similar photochromic characteristics to halogen lamps was developed. Additionally, CFD was applied to optimize the LED's heat dissipation performance. A prototype was produced and its performance was verified through experiment. (C) 2015 Elsevier Ltd.
