Abstract
A vehicle light system includes an LED lamp mounted to an outer body of a vehicle. The LED lamp includes a frame, a diode array having a plurality of individual diodes fixed relative to the frame, and a control unit fixed relative to the frame. The control unit controls a current flow to the diode array and measures a value indicative of the current flow to the diode array. The control unit further compares the measured value to a cut-off value, the cut-off value being a parameter that is indicative of a luminous intensity of the LED lamp. If the measured value is less than the cut-off value, the control unit cuts the current flow to the diode array such that the LED lamp is turned off.

10. A method for testing an LED lamp for a vehicle, the LED lamp including a frame, a diode array having a plurality of individual diodes fixed relative to the frame, and a control unit fixed relative to the frame, the method comprising:
-
providing power to the diode array; connecting a testing device to the diode array, the testing array configured to measure a value indicative of current flow to the diode array; measuring a luminous intensity of the LED lamp at a first distance and a first angle using a measuring device; and determining if the measured luminous intensity is greater than or equal to a threshold luminous intensity, wherein, if the measured luminous intensity is determined to be greater than or equal to the threshold luminous intensity, the method further comprises deactivating one individual diode and repeating the steps of measuring the luminous intensity of the LED lamp at the first distance and the first angle and determining if the measured luminous intensity is greater than or equal to the threshold luminous intensity, and wherein, if the measured luminous intensity is determined to be less than the threshold luminous intensity, the method further comprises measuring the value indicative of the current flow to the diode array using the testing device. - View Dependent Claims (11, 12, 13, 14, 15)

16. A vehicle light system, the system comprising:
-
an electronic control unit for a vehicle; and an LED lamp configured to mount to an outer body of the vehicle, the LED lamp comprising; a frame; a diode array having a plurality of individual diodes fixed relative to the frame; a control unit fixed relative to the frame and in communication with the electronic control unit, the control unit configured to; control a current flow to the diode array; measure a value indicative of the current flow to the diode array; compare the measured value to a cut-off value, the cut-off value being a parameter that is indicative of a luminous intensity of the LED lamp, wherein, if the measured value is less than the cut-off value, the control unit is further configured to communicate to the electronic control unit that the measured value has becomes less than the cut-off value, and wherein the electronic control unit is configured to alert a driver of a need for replacement of the LED lamp when the measured value is less than the cut-off value. - View Dependent Claims (17, 18, 19, 20)
