Light guide module with adjustable contour surface illumination

摘要

A light guide module with adjustable lighting of a contour surface is composed of light sources and a light guide. The light guide is composed of a primary part, a Y-shaped branch, and a secondary part with a contour surface. The supporting surface of the Y-shaped branch of the light guide is composed of a system of directional optical elements, is of prismatic shape, conical shape, or a combination thereof, and has a vertex on the optical axis of the primary part of the light guide.

主权项

1. A light guide module with adjustable lighting of a contour surface comprising:
at least one light source; and a light guide in optical communication with the light source, the light guide having a primary part having an optical axis, a secondary part having a curved contoured surface configured to emit light, and a Y-shaped branch disposed between the primary part and the secondary part, the Y-shaped branch having a supporting surface and a vertex, the supporting surface defined by a channel in the rear surface of the secondary part; wherein the supporting surface includes a plurality of individual directional optical elements disposed thereon and the vertex is disposed on the optical axis of the primary part, and each individual directional optical element is configured to redirect light from the at least one light source to the contoured surface; wherein the channel is an elongated channel having a first rounded end, a second rounded end, a straight portion extending therebetween, and wherein the first and second rounded ends each comprise directional optical elements having a conical shape, and the straight portion comprises directional optical elements having a planar shape, the channel including a planar shape having a first linear edge surface and a second linear edge surface.
