    • The headlamp system of the present invention includes a source array of semiconductor light sources and a lens system to produce a first component, such as spread light, of desired beam patterns and a source array of semiconductor light sources and a lens system to produce a second component, such as the hot spot components, of the desired beam patterns. Light from the semiconductor light sources of each source array is transferred to the respective lens system by a transfer device comprising a series of light pipes which capture light emitted by the semiconductor light sources and emit the captured light adjacent the respective lens systems. One or both source arrays can include additional semiconductor light sources which are selectively illuminated or extinguished to provide steering hot spots in the beam pattern to illuminate areas adjacent the vehicle over which the vehicle will be turned.
    • 本发明的前照灯系统包括半导体光源的源极阵列和用于产生所需波束图案的第一分量(例如扩展光)和半导体光源的源阵列的透镜系统以及用于产生第二 组件,例如热点组件,所需的波束图案。 来自每个源阵列的半导体光源的光通过包括一系列光管的传送装置传送到相应的透镜系统,该系列的光管捕获由半导体光源发射的光并发射与相应的透镜系统相邻的捕获的光。 一个或两个源阵列可以包括附加的半导体光源,其被选择性地照明或熄灭以在波束图案中提供转向热点以照亮车辆将被转动的车辆附近的区域。
