High definition vehicular mirror
View Patent ↗A vehicle mirror assembly having a housing or base member, a mirror lens and a connecting gasket member. The mirror lens is provided in the shape of a portion of an end of an ellipsoid. The lens has a varying radius of curvature. The center portion of the lens has a smaller radius of curvature than the outer portions along the major axis of the lens creating an improved field of view of the reflected image.
1. A mirror lens assembly comprising:
a mirror lens member comprising a first base periphery, a second base periphery and a dome lens, said mirror lens member comprising a slice of a geometric shape having a minimum radius of curvature positioned in between said first base periphery and said second base periphery and a varying dome lens radius of curvature increasing from said minimum radius of curvature towards said first base periphery and said second base periphery;
said slice being taken through an axis of said geometric shape and said slice intersecting said axis in a non-perpendicular manner.
2. A mirror lens assembly as described in claim 1 , wherein said geometric shape comprises a geometric shape formed by the rotation of an ellipse.
3. A minor lens assembly as described in claim 2 , wherein said geometric shape comprises an ellipsoid.
4. A minor assembly as described in claim 1 , wherein said varying dome lens radius of curvature is greater at said first base periphery than at said second base periphery.
5. A mirror assembly as described in claim 1 , wherein said minimum, value is not positioned in the center of said dome lens.
6. A mirror assembly as described in claim 1 , wherein said first base portion is parallel to said second base portion.
7. A mirror assembly comprising:
a mirror tens member comprising a dome lens generally configured to conform to a geometric shape formed using an ellipse, said mirror lens member comprising a first base portion and a second base portion comprising an intersection of an axis of said ellipse; said intersection being non-perpendicular to said axis.
8. A mirror assembly as described in claim 7 , wherein said axis of said ellipse comprises a major axis.
9. A vehicle minor assembly comprising:
a mirror lens member having a varying dome radius of curvature substantially conforming to a slice of an ellipse based geometric form, said slice taken non-perpendicular to an axis of said ellipse based geometric form.
10. A vehicle mirror assembly as described in claim 9 , wherein said ellipse based geometric form is generally an ellipsoid.
