Abstract

PURPOSE:To design the light emission aperture more freely and to reduce the restriction to the design of the car by cutting a part of two parabolic reflectors, which are opposite to each other and have a common focus, to make it a light emission aperture. CONSTITUTION:Silver plating between A-A on the surface of one of the parabolic reflectors 2, 3, which are opposite to each other and have a common focus 1, is removed to make the part a light emission aperture of clear glass, it is a desired headlight. When the light source is placed at the focus 1, the ray that reaches the aperture A-A from the light source and the ray reflected from the upper part of the reflector 2 are emitted from the aperture to the outside. The ray that reaches the lower part of the reflectors 2, 3 is reflected from each reflector to make itself a parallel ray, reflected from the opposite reflector to converge itself to the focus 1, and is emitted from the aperture to the outside. In this way, the lower half part of the headlight can be located at the back of the bumper 4, the lower nose of car can be designed.
