Abstract
Official abstract text for this publication.
A light guide ( 201 ) including a transparent element is presented. The transparent element includes an optical diverter section ( 204 ) including one or more reflective surfaces ( 205 ) forming walls of a notch ( 206 ) extending into the diverter section, where the reflective surfaces provide total reflections for directing light into directions lateral with respect to an arrival direction of the light. The transparent element includes an optical channel section ( 208 ) for receiving the light from a light source and for directing the light to the optical diverter section. The optical channel section includes a side surface ( 209 ) shaped to provide total reflections for directing light to the optical diverter section. The optical channel section makes it possible to place the light source a distance apart from the optical diverter section and also to prevent or at least to reduce direct propagation of light from the light source to the lateral directions.
First claim
Opening claim text (preview).
What is claimed is: 1. A light guide for modifying a light distribution pattern of a point-form light source, comprising: a transparent element made of transparent material having refractive index greater than unity, the transparent element having an optical diverter section that comprises: reflective surfaces constituting walls of an apex extending into the diverter section, the reflective surfaces being shaped to provide total reflections for directing light into directions l…
