A light bar assembly (100) configured to be mounted at a rim of a steering wheel (100) of a vehicle is disclosed. The light bar assembly (100) may include components of a driver monitoring system. The light bar assembly includes a PCB bar (139) having a plurality of visible and infrared LEDs (172, 173) and an LED driver (131). The PCB strip (139) is coupled to a support plate (127) of a housing (120) surrounding the PCB strip. The support plate (127) transfers heat generated by the LED and LED (172, 173) drivers away from the PCB strip (139).
公开了被配置成安装在车辆的方向盘(100)的轮缘处的灯条组件(100)。该灯条组件(100)可包括驾驶员监视系统的部件。该灯条组件包括PCB条(139),该PCB条具有多个可见光LED和红外LED(172,173)和LED驱动器(131)。该PCB条(139)联接到包围该PCB条的外壳(120)的支撑板(127)。该支撑板(127)将由该LED和LED(172,173)驱动器生成的热量传递远离该PCB条(139)。
