Abstract
A lens for forming a predetermined pattern from a light source includes a first region of an inner surface configured to receive light from the light source and to bend the light into a first line segment. The lens includes a second region of the inner surface configured to receive the light from the light source and to bend the light into a second line segment perpendicular to the first line segment, the first line segment forming a cross of a “T” and the second line segment forming the stem of the “T.”
Claims20
A lens for forming a predetermined pattern from a light source, comprising:
- a first region of an inner surface configured to receive light from the light source and to bend the light into a first line segment;
- and
- a second region of the inner surface configured to receive the light from the light source and to bend the light into a second line segment perpendicular to the first line segment, the first line segment forming a cross of a “T” and the second line segment forming the stem of the “T.”
A lens assembly, comprising:
- a base board;
- a light source mounted to the base board;
- and
- a lens mounted to the base board and having an inner surface defining a cavity, such that the light source is located in the cavity, the inner surface of the lens having a first region configured to receive light from the light source and to bend the light to form a first line segment, and the inner surface of the lens having a second region configured to receive the light from the light source and to bend the light to form a second line segment perpendicular to the first line segment, such that the first line segment forms a cross of a “T” shape and the second line segment forms a stem of the “T” shape.
