LIGHT SYSTEM FOR LIFT GATES

摘要

An embodiment of a lighting device (12) for a lift gate includes one or more sensors (18), each sensor configured to generate an output signal based on motion and/or orientation thereof, wherein each sensor is coupled to a movable member (14) of the lift gate to generate an output signal indicating a motion and/or position state of said movable member of the lift gate; a controller circuit (16) coupled to each sensor to receive an output signal from each sensor, wherein the controller circuit is configured to generate one or more control signals for controlling operation of one or more lighting elements; and one or more lighting elements (13) coupled to the controller circuit to receive control signals from the controller circuit; wherein the controller circuit is configured to generate one or more control signals in response to the output signals from each sensor, for controlling operation of one or more lighting elements based on sensed state of the moveable member.
