Abstract
The present invention relates to improvements in controlling the direction of light rays and apparatus incorporating the improvements.
Claims34
An apparatus, comprising:
- a mirror element comprising at least one substrate comprising a reflective layer on at least a portion of a surface thereof;
- and
- two differently functioning indicia formed in said reflective layer, functions of said two indicia being selected from the group consisting of a supplemental turning indicator, keyhole/door illuminator, and a side object detection indicator, wherein both of said at least two indicia are defined by one contiguous line opening through said reflective layer.
An apparatus, comprising:
- a mirror element comprising at least one substrate comprising a reflective layer on at least a portion of a surface thereof;
- at least one indicia formed in said reflective layer, said at least one indicia defines one contiguous line having a width less than approximately 2.0 mm and opening through said reflective layer;
- and
- at least two light sources configured to project light rays through said contiguous line.

An apparatus, comprising:
- an electro-optic mirror element comprising at least one substrate comprising a reflective layer on at least a portion of a surface thereof;
- at least one indicia formed in said reflective layer, said at least one indicia defined by one contiguous line having a width of less than approximately 2.0 mm and opening through said reflective layer;
- and
- at least one light source configured to project light rays through said contiguous line.
1 more element
An apparatus, comprising:
- a mirror element comprising at least one substrate comprising a reflective layer on at least a portion of a surface thereof;
- at least one contiguous line opening through said reflective layer, said line having a width of less than approximately 2.0 mm;
- and
- at least one light source configured to project light rays through said contiguous line substantially in a preferred direction, wherein a luminous intensity is greater than or equal to approximately 5.0 candelas.
