发明名称 Vehicle lamp unit
摘要 A vehicle lamp unit includes an LED having a high directivity as a light source and a reflective surface that reflects a light from the LED. The reflective surface is based on a paraboloid of revolution with the LED as a focal point, and divided into a plurality of reflecting portions, including a plurality of first reflective surfaces that reflects light beams within a half-value angle in a first predetermined direction, and a plurality of second reflective surfaces that reflects light beams out of the half-value angle in a second predetermined direction. A focal length of the paraboloid of revolution for the first reflective surfaces is smaller than that of the paraboloid of revolution for the second reflective surfaces.
