Extreme cutoff beam control optics

An optical assembly comprising:

• at least one lens having a lens central axis;
• at least one light emitting diode (LED) oriented to emit light into the at least one lens, the at least one LED having an optical axis;
• and
• at least one curved reflector disposed adjacent to the at least one LED such that the at least one LED is at a first side of the at least one curved reflector, wherein the at least one curved reflector has a reflective surface extending over the at least one LED and beyond the optical axis,
• wherein the at least one LED is configured to emit light from the optical assembly and wherein the optical assembly is configured to direct at least 95% of the emitted light in a first direction relative to a light cutoff plane (1) that extends through the optical axis of the at least one LED located within the optical assembly at a location most distal from the first direction and (2) that extends parallel to the optical axis and perpendicular to the first direction.

An optical assembly comprising:

• a base having a surface and defining at least one aperture;
• at least one lens having a dome shape portion and a lens central axis, wherein the at least one lens is coupled to the base and extends through the at least one aperture so as to be visible on the surface;
• at least one light emitting diodes (LED) oriented to emit light into the at least one lens and the at least one LED having an optical axis;
• and
• at least one curved reflector disposed adjacent to the at least one LED such that the at least one LED is at a first side of the at least one curved reflector, wherein the at least one curved reflector has a reflective surface extending over the at least one LED and beyond the optical axis of the at least one LED and
• wherein the dome shape portion of the at least one lens extends from the surface and wherein the surface is configured to absorb at least 90% of light incident on the surface.

An optical assembly comprising:

• a base comprising a first surface, a second surface opposite the first surface, and at least one aperture extending through the base from the first surface to the second surface;
• at least one lens coupled to the base, the at least one lens having a lens central axis perpendicular to a plane of the base, wherein the at least one lens is attached to the second surface of the base and extends at least partially through the at least one aperture so as to be at least partially exposed on the first surface of the base;
• at least one light emitting diode (LED) positioned to emit light into the at least one lens, the at least one LED having an optical axis;
• and
• at least one curved reflector disposed adjacent to the at least one LED such that the at least one LED is at a first side of the at least one curved reflector, wherein the at least one curved reflector comprises a curved surface defined at least partially by connected line segments such that the at least one curved reflector curves over the at least one lens and extends beyond the optical axis of that the at least one LED,
• wherein the line segments comprise a linear segment extending perpendicularly to the base.
