    • A standalone gradient detector system, utilizing a gradient detector with a several photodetectors, is disclosed. A lamp emits light toward a screen. The light strikes the photodetectors on a photodector array, which communicate the light intensity to a gradient circuit. The gradient circuit compares the intensity values from each photodetector with the intensity value for the photodetector immediately adjacent, and computes a gradient value. The maximum gradient value is displayed using a display device, and the position of the photodetector with the maximum gradient value is indicated by an adjacent light source. The gradient of an automobile headlamp may thus be found easily, assisting in headlamp positioning during headlamp and vehicle manufacture.
    • 公开了一种利用具有多个光电检测器的梯度检测器的独立梯度检测器系统。 灯会朝向屏幕发光。 光照射光电二极管阵列上的光电探测器,其将光强度传递给梯度电路。 梯度电路将来自每个光电检测器的强度值与紧邻的光电探测器的强度值进行比较,并计算梯度值。 使用显示装置显示最大梯度值,并且由相邻光源指示具有最大梯度值的光电检测器的位置。 因此可以容易地发现汽车前照灯的梯度,在前照灯和车辆制造过程中辅助头灯定位。

    • An automotive lamp assembly includes a light source and a hyperbolic reflector positioned to reflect light from the light source. A bifocal lens is positioned in front of the light source and hyperbolic reflector such that it receives light emitted from the light source and light reflected off the reflector. The bifocal lens includes a first portion having a focal point at the light source and a second portion having a focal point at a virtual focus of the reflector. When the light source is energized and emits light, direct light from the light source strikes the first portion of the lens and collimates the light substantially parallel to the optical axis. Light from the reflector strikes the second portion of the lens and is collimated substantially parallel to the optical axis. Altogether, the light passing through the bifocal lens provides a desirable light beam for an automotive vehicle.
    • 汽车灯组件包括光源和定位成反射来自光源的光的双曲反射器。 双焦点透镜位于光源和双曲反射器的前面,使得它接收从光源发射的光和从反射器反射的光。 双焦点透镜包括具有在光源处的焦点的第一部分和具有位于反射器的虚焦点处的焦点的第二部分。 当光源被激发并发光时,来自光源的直射光照射到透镜的第一部分并使基本平行于光轴的光准直。 来自反射器的光照射到透镜的第二部分并且基本上平行于光轴准直。 总之,通过双焦点透镜的光为机动车辆提供期望的光束。
