Langgestreckter Scheinwerfer

摘要

With headlamps of the related configuration, the amount of light in a horizontal direction is insufficient when the width of a reflector is narrowed, and a broad light distribution in the horizontal direction is therefore difficult. This imposes design limitations. In the present invention, an oblong headlamp (1,10) comprises a first reflector (3) and a third reflector (5) constituted by two ellipse group reflectors and sharing one light source (2) at a first focal point, wherein a second focal point of the first reflector (3) is above its first focal point and a second focal point of the third reflector (5) is positioned below its first focal point in reference to the direction of illumination, comprising further a second parabolic group reflector (4) positioned above the first reflector (3) having a focal point at the second focal point of the first reflector (3), and a fourth parabolic group reflector (6) positioned below the third reflector (5) having a focus at thesecond focal point of the third reflector (5). Light from the light source (2) converged by the first ellipse group reflector (3) and third reflector (5) is then supplied to the second (4) and fourth (6) parabolic group reflectors and a bright oblong headlamp is therefore made possible.
