LIGHT EMITTING DIODE HEADLAMP FOR A VEHICLE
First Claim
1. A vehicle exterior lamp comprising a plurality of light emitting diodes (LEDs) positioned into an array, the array having at least one row and at least two columns, each LED positioned at an intersection thereof, wherein at least one of the LEDs is illuminated by selectively applying a signal to the row and a signal to the column corresponding to the position of the LED.

Abstract
A vehicle exterior lamp is provided with an array of light emitting diodes (LEDs) with rows and columns and each LED positioned at an intersection thereof. An LED is illuminated by selectively applying a signal to the row and column corresponding to the LED position. A vehicle headlamp lighting system is provided with an array of LEDs with rows and columns, and each LED positioned at a row and column intersection. The lighting system has a control module for selectively illuminating the LEDs by applying a signal to the rows and to the columns corresponding to the location of the LEDs to be illuminated. A vehicle headlamp is provided with an optical structure for reflection and refraction of light and LEDs. Light emitted by the LEDs interacts with the optical structure and exits the headlamp in a generally perpendicular direction to the LED emitted light.

19. A lighting system for a vehicle headlamp, the lighting system comprising:
-
a plurality of light emitting diodes (LEDs) arranged into a first and a second array, each array having at least two rows and at least one column, each LED positioned at a row and column intersection; and a control module for selectively illuminating at least one of the plurality of LEDs, the control module applying a signal to at least one row and a signal to at least one column corresponding to the location of the LEDs to be illuminated.

20. A vehicle headlamp comprising:
-
an optical structure for at least one of reflection and refraction of light; and a plurality of light emitting diodes (LEDs) for selectively emitting light; wherein light emitted by the LEDs is directed towards the optical structure, interacts with the optical structure, and the light then exits the headlamp in a generally perpendicular direction to the LED emitted light.
