Abstract
A dynamic segmented-reflector for a vehicle headlamp that includes a light source and a substrate formed as a reflector sidewall. The reflector sidewall includes reflector facets that are grown on the reflector sidewall. The reflector facets include at least one mirrored surface that faces the light source, and the reflector facets are configured to adjust position to form different light patterns.
Claims7
A reflector for a vehicle headlamp, comprising:
- a curved reflector sidewall substrate that outwardly extends from a center portion to form a peripheral edge and that includes a concave surface and a convex surface opposite to the concave surface, the convex surface is connected to the concave surface by the peripheral edge;
- a planar circuit board that extends perpendicular to the curved reflector sidewall substrate;
- a light source that is located on the planar circuit board adjacent to the peripheral edge of the curved reflector sidewall substrate and that emits light toward the curved reflector sidewall substrate;
- and
- a plurality of reflector facets that outwardly extend from only the concave surface of the curved reflector sidewall substrate, that include at least one mirrored surface that faces the light source, that are configured to reflect light to form a plurality of patterns, and that are configured to adjust to form the plurality of light patterns.

A method for controlling a dynamic reflector comprising:
- adjusting a plurality of reflector facets grown on only a concave surface of a curved reflector sidewall substrate of a dynamic segmented-reflector to form a first light pattern arrangement of the plurality of reflector facets from light emitted from a light source on a planar circuit board located perpendicular to the curved reflector sidewall substrate;
- and
- adjusting the plurality of reflector facets grown on the curved reflector sidewall substrate of the dynamic segmented-reflector to form a second light pattern arrangement of the plurality of reflector facets different from the first light pattern arrangement, wherein
- the curved reflector sidewall of the dynamic segmented-reflector includes a convex surface opposite to the concave surface, the convex surface of the curved reflector sidewall is connected to the concave surface by a peripheral edge.

A method for controlling a dynamic reflector comprising:
- adjusting an arrangement of a plurality of reflector facets grown on only a concave surface of a curved reflector sidewall substrate of a dynamic segmented-reflector to form a first light pattern arrangement from light emitted from a light source on a planar circuit board adjacent to the curved reflector sidewall substrate;
- detecting oncoming traffic via a light sensor;
- transmitting a signal to a controller that indicates the detection of oncoming traffic in response to the detection of oncoming traffic;
- and
- adjusting the arrangement of the plurality of reflector facets grown on the curved reflector sidewall substrate of the dynamic segmented-reflector to form a second light pattern arrangement different from the first light pattern arrangement that spreads emitted light of the dynamic segmented-reflector away from oncoming traffic, wherein
- the curved reflector sidewall substrate of the dynamic segmented-reflector includes a convex surface opposite to the concave surface, the convex surface of the curved reflector sidewall substrate is connected to the concave surface by a peripheral edge.
