Abstract
A light guide assembly includes a metal material printed circuit board. A light emitting diode is mounted on and extends away from a first face of the printed circuit board. A light guide molded from a light transmissive polymeric material is positioned proximate to the light emitting diode and is at least partially received in a concomitantly shaped through bore pre-formed in the printed circuit board. The light guide includes an extended feature co-molded from the same material as the light guide and extending away from the first face of the printed circuit board in an installed position of the light guide. The extended feature includes a first extended feature having a first length and a second extended feature having a second length, the second length greater than the first length.

A light guide assembly, comprising:
- a printed circuit board;
- a light emitting diode mounted on a first face of the printed circuit board;
- a light guide molded from a light transmissive polymeric material positioned proximate to the light emitting diode, the light guide including an extended feature for positioning the light guide into a mold, the extended feature co-molded from the same material as the light guide and extending away from the first face of the printed circuit board in an installed position of the light guide.
A light guide assembly, comprising:
- a metal material printed circuit board;
- a light emitting diode mounted on and extending away from a first face of the printed circuit board;
- a light guide molded from a light transmissive polymeric material positioned proximate to the light emitting diode, and at least partially received in a concomitantly shaped through bore pre-formed in the printed circuit board;
- and
- the light guide including an extended feature co-molded from the same material as the light guide and extending away from the first face of the printed circuit board in an installed position of the light guide, the extended feature including a first extended feature having a first length and a second extended feature having a second length, the second length greater than the first length.
A light guide assembly, comprising:
- a metal material printed circuit board;
- a light emitting diode mounted on and extending away from a first face of the printed circuit board;
- a light guide pre-molded from a light transmissive polymeric material positioned proximate to the light emitting diode, and at least partially received in a concomitantly shaped through bore pre-formed in the printed circuit board;
- the light guide including an extended feature co-molded from the same material as the light guide and extending away from the first face of the printed circuit board in an installed position of the light guide, the extended feature including a first extended feature having a first length and a second extended feature having a second length, the second length greater than the first length;
- a white film individually applied or ink printed over the light guide without contacting any portion of the first face of the printed circuit board;
- and
- an opaque polymeric material applied onto the first face of the printed circuit board using an injection molding process after installation of the light guide, the first extended feature abutting against a wall of a mold to predetermine a thickness of the opaque polymeric material, and the second extended feature partially received within an aperture of the wall of the mold to position the light guide within the mold.
