Title (EN) COLLIMATING LIGHT GUIDE
(FR) GUIDE DE LUMIÈRE DE COLLIMATION
Abstract:
(EN) A light guide includes a light input surface, a first major surface orthogonal to the light input surface, a second major surface opposing the first major, a plurality of discrete light extraction features disposed on the second major surface and a plurality of closely packed prisms disposed along the second major surface. The plurality of discrete light extraction features separate the plurality of closely packed prisms from the second major surface. Each of the closely packed prisms include a first prism surface forming a first angle with the second surface in a range from 80 to 100 degrees or in a range from 85 to 95 degrees or in a range from 87 to 93 degrees.
(FR) L'invention concerne un guide de lumière qui comprend une surface d'entrée de lumière, une première surface principale orthogonale à la surface d'entrée de lumière, une seconde surface principale opposée à la première surface principale, une pluralité de caractéristiques d'extraction de lumière discrètes disposées sur la seconde surface principale et une pluralité de prismes disposés très rapprochés les uns des autres le long de la seconde surface principale. Les multiples caractéristiques d'extraction de lumière discrètes séparent les multiples prismes disposés très rapprochés les uns des autres de la seconde surface principale. Chacun des prismes disposés très rapprochés les uns des autres comprend une première surface de prisme formant un premier angle avec la seconde surface dans une plage de 80 à 100 degrés ou dans une plage de 85 à 95 degrés ou dans une plage de 87 à 93 degrés.
