    • There is described a lighting system for vehicles comprising light emitting diodes (20) mounted on printed circuit boards (PCBs). Auxiliary components such as speakers are mounted on some of the PCBs lighting modules (10,20) which are connected in an end-to-end relationship and which form light rows of the lighting system. Electrical traces for the auxiliary components (33) form part of the PCBs. This results in a substantial reduction in or elimination of wiring. Connectors at each end of a PCB are compatible with the connectors on a neighboring PCB and are optionally connectable with a respective corresponding connector assembly of another lighting module (10,20) in a direction substantially normal to the planar mounting surface of the PCB or in a direction substantially parallel to the planar mounting surface.
    • 描述了一种用于车辆的照明系统,其包括安装在印刷电路板(PCB)上的发光二极管(20)。 诸如扬声器的辅助部件安装在以端对端关系连接并且形成照明系统的轻行的一些PCB照明模块(10,20)上。 辅助部件(33)的电气迹线构成PCB的一部分。 这导致了布线的显着减少或消除。 PCB的每一端处的连接器与相邻PCB上的连接器兼容,并且可选地可以与基本上垂直于PCB的平面安装表面的方向上的另一照明模块(10,20)的相应对应的连接器组件相连,或者 大致平行于平面安装表面的方向。
