Luminescent, ultraviolet protected automotive interior members

A method of illuminating an interior area of a motor vehicle comprising:

• injection molding at least one photoluminescent interior member having a thickness of 1.5 mm to 2.5 mm, wherein the injection molded photoluminescent interior member is formed of a plastic composition, wherein the plastic composition comprises a blend of at least one polymer and a plurality of additives comprising at least one photoluminescent material and at least first ultraviolet protector;
• wherein the at least one photoluminescent material absorbs electromagnetic radiation in a first ultraviolet range of an electromagnetic spectrum, and thereafter emits electromagnetic radiation in a visible radiation range of the electromagnetic spectrum;
• wherein the first ultraviolet protector is an ultraviolet absorber, wherein the ultraviolet absorbs electromagnetic radiation in a second ultraviolet range of the electromagnetic spectrum and does not absorb electromagnetic radiation in the first ultraviolet range of the electromagnetic spectrum;
• and
• absorbing electromagnetic radiation in the first range of the electromagnetic spectrum with the at least one photoluminescent material, and thereafter emitting electromagnetic radiation in the visible radiation range of the electromagnetic spectrum to illuminate the interior area of the motor vehicle.
