摘要： Light distribution characteristics are defined which define a correspondence relation between the position of a reflection point on a reference plane and the position of an image of a light source. In accordance with the light distribution characteristics, a path line in the reference plane is determined. A profile curve for each of a plurality of sampling points dispersibly distributed on the path line, is determined in accordance with the light distribution characteristics, the profile curve passing through the sampling point and corresponding to the topological shape of a reflecting surface to be determined. As the reflection point moves along the profile curve, the image of the light source moves in the direction crossing the reference plane in accordance with the light distribution characteristics. The topological shape of the reflecting surface is determined in accordance with the profile curve determined for each sampling point.

摘要： An improved signal lamp for a vehicle is composed of a plurality of dome type light emitting diodes and a plurality of reflective mirrors arranged corresponding to the light emitting diodes. Each of the reflective mirrors is designed in the shape of a rotational parabolic surface whose focus is located at the position coincident to the foremost end of the corresponding light emitting diode or at the position in the vicinity of the foremost end of the corresponding light emitting diode. The rotational parabolic surface is configured such that a virtual light source appearing on each light emitting diode is located at the position coincident with the focus of the corresponding reflective mirror or at the position in the vicinity of the focus of the corresponding reflective mirror. Each light emitting diode chip is sealably received in a transparent cylindrical case molded of synthetic resin such that a large part of light generated by the light emitting diode chip is emitted directly from the light emitting diode chip so as to allow it to be radiated to the outside through the lens portion at a radiating angle ranging from 10.degree. to 12.degree. as measured from the optical axis.
摘要翻译：用于车辆的改进的信号灯由多个圆顶型发光二极管和对应于发光二极管布置的多个反射镜组成。每个反射镜被设计成旋转抛物面的形状，其焦点位于与相应的发光二极管的最前端一致的位置处或者在相应的发光二极管的最前端附近的位置。旋转抛物面被配置为使得出现在每个发光二极管上的虚拟光源位于与相应反射镜的焦点重合的位置处或者在相应反射镜的焦点附近的位置处。每个发光二极管芯片可密封地接收在由合成树脂模制的透明圆柱形壳体中，使得由发光二极管芯片产生的大部分光直接从发光二极管芯片发射，以便将其发射到以从光轴测量的10°至12°的辐射角通过透镜部分外部。
