LIGHT GUIDING LENS AND VEHICLE LIGHTING UNIT

摘要

A light guiding lens and vehicle lighting unit are shown. According to one aspect, an elongated light guiding lens guides and emits light emitted from LEDs. The light guiding lens includes a first rod extension and a second rod extension connected with each other, and a flange protruding from the first rod extension. The flange includes a plurality of light incident portions to introduce light into the flange. The light incident portions guide light toward the first rod extension along a light guiding direction and lies in the direction toward the second rod extension, the light guiding direction defining an acute intersecting angle with the extending direction of the first rod extension. The first rod extension includes reflecting surfaces to internally reflect the light incident on the light incident portions and guided inside the flange.

1. An elongated light guiding lens guiding and emitting light emitted from a plurality of LEDs, the light guiding lens comprising:
a first rod extension and a second rod extension connected with each other; and a flange protruding from the first rod extension, wherein the flange includes a plurality of light incident portions corresponding to the respective LEDs and introducing light emitted from the LEDs into the flange, the light incident portions are disposed at different sites in a crossing direction intersecting with an extending direction of the first rod extension at an acute angle, the light incident portions guide light emitted from the respective LEDs inside the flange toward the first rod extension along a light guiding direction which is perpendicular to the crossing direction and lies in the direction toward the second rod extension, the light guiding direction defining an acute intersecting angle with the extending direction of the first rod extension, and the first rod extension includes a plurality of reflecting surfaces to internally reflect the light incident on the light incident portions and guided inside the flange along the extension direction toward the second rod extension.
