Patent ID: 8366304

Claim:
A lighting device for a motor vehicle, comprising: a single printed circuit board; a plurality of light-emitting diode-type light sources having, at least one first set of light-emitting diodes and at least one second set of light-emitting diodes, said at least one first set of light-emitting diodes and said at least one second set of light emitting diodes being mounted on said single printed circuit board; a single diffusion screen covering each of said single printed circuit board, said at least one first set of light emitting diodes and said at least one second set of light emitting diodes to provide a single internal lighting module; said at least one first set of light emitting diodes comprising at least one axial-emission or through-emission diode that emits a light beam in a main direction substantially perpendicular to said single printed circuit board, and said at least one second set of light-emitting diodes comprising at least one lateral-emission diode that emits a light beam in a direction generally parallel to a plane of the single printed circuit board; said single printed circuit board being connected to a microcontroller by at least three conductors, with a first conductor comprising an earth or ground conductor, a second conductor allowing a vehicle voltage to be applied to said at least one first set of light-emitting diodes, and a third conductor allowing a vehicle voltage to be applied to said at least one second set of light emitting diodes; wherein said single lighting module is mounted in a passenger compartment of said vehicle and said at least one first set of light-emitting diodes perform a first lighting function corresponding to reception lighting when a person enters the passenger compartment or when an engine of the vehicle is stopped; and said at least one second set of light-emitting diodes perform a second lighting function corresponding to an ambient lighting inside the passenger compartment so as to not disturb a driver.
