Due to the energy crisis, the issue about how to improve the efficiency of lighting gains popularity. Many
researches focus on using LED to be the light source of car lamps because LED has the advantages, such as low power
consumption, adjustable luminous intensity, high color rendering index, long lifetime, and short reaction time, and the
car lamps will become smaller and lighter. In our design, the LED headlamp consists three parts: a double ellipsoidal
reflector, an aspherical lens, and a baffle. The double ellipsoidal reflector can improve the luminous flux in front of the
headlamp and provide adequate illumination; the aspherical lens can eliminate spherical aberration; and the designed
location of baffle can solve the glare problems. According to the optical simulation, the design successfully fits the
request of intensity distribution in the ECE regulation.
