Low profile optical lighting assembly for use in outside vehicle mirror and method of forming same

摘要

An optical lighting assembly for use with a vehicular outside rearview mirror includes a printed circuit board (PCB) having a light source such as a light emitting diode (LED) mounted thereon. An optical device such as a light pipe is positioned adjacent to the LED for propagating light away from the LED. A mirror element includes at least one indicia where light escaping from the light pipe is used to illuminate the indicia.

主权项

1. A low profile optical lighting assembly for use in an outside vehicular mirror comprising:
at least one light source mounted to a first side of a printed circuit board (PCB) so as to project light through a gap in the PCB to a second side of the PCB, wherein the light source has a height extending from the first side; a lens optic device positioned on the second side of the PCB from the at least one light source and separated from the light source, wherein the lens optic device is configured to receive light from the light source and spread the light over an aperture larger than the gap, the aperture corresponding to at least one indicia; a mirror element arranged parallel to the PCB comprising the at least one indicia, wherein light passing through the lens optic device illuminates the at least one indicia, wherein the PCB and the mirror element are substantially parallel to provide for the low profile; and a cover member in direct contact with the first side of the PCB and forming a space approximately the height of the light source from the PCB.
