LIGHTING DEVICE CONTAINING A CURED LIGHT WAVEGUIDE EQUIPPED WITH MEANS FOR EXPLOITING THE SPOILING

摘要

The device has an optical light guide with an end face to introduce light rays. An emission section has a lateral surface that forms a light beam emission face. A bend (28) is interposed between the introduction face and the section. A wedge of the bend projects toward exterior and beveled to present upper and lower facets (30, 32) to reflect incident light rays, where a part of rays escapes outside the guide through the facets. Prisms (34A, 34B) modify orientation of the escaped rays, such that the escaped rays complete a light beam from the emission face in homogenous and continuous manner.
