Abstract: An apparatus (200, 300, 400, 500) includes a lighting driver circuit (210, 310, 410, 510) and a housing (220, 420, 520) in which the lighting driver circuit is disposed. The lighting driver circuit is configured to receive an input voltage (10) between a pair of input terminals (305) and in response thereto to supply power to one or more light sources (20). The housing has an electrically insulating inner surface (222, 422, 522) and an electrically insulating outer surface (228, 428, 528) and an electrically conductive electromagnetic shield layer (226, 426, 526). The electrically conductive electromagnetic shield layer is disposed between the electrically insulating inner surface and the outer electrically insulating surface. The lighting driver circuit is electrically connected to the electrically conductive electromagnetic shield layer of the housing.

Abstract: A low voltage electronic module interface, with a low voltage interface for an electronic module receiving a constant current from a body control module, the interface including a reverse current protection circuit 152; and a switch 154 operably connected in series with the reverse current protection circuit 152, the switch 154 being responsive to a status signal 144. The reverse current protection circuit 152 and the switch 154 form a low voltage electronic module interface circuit 150 having a resistance; and the resistance is selected so voltage across the low voltage electronic module interface circuit 150 is less than 2.70 Volts when the switch 154 is closed and the constant current 124 flows through the low voltage electronic module interface circuit 150.

Abstract: A current limiting controller (100) for a light emitting diode (LED) driver automatically resets the LED driver to normal operation after elimination of a fault. The current limiting controller (100) includes a fault detector to detect a fault across a load (20, 40) that is being driven by the driver circuit (10, 30); a current limiter (130, 230) to limit the current supplied from the driver circuit (10, 30) to the load (20, 40) in response to the detected fault; and a reset circuit (120, 220, 320) to disable the current limiter (130, 230) upon expiration of a first time interval after the fault is detected, and to allow the current limiter (130, 230) again to limit the current supplied from the driver circuit (10, 30) to the load (20, 40) when the detected fault remains after a second time interval.
