Title
(EN) ILLUMINATION CONVERTER
(FR) CONVERTISSEUR D'ÉCLAIRAGE
Abstract
(EN)
The disclosure generally relates to illumination converters that are capable of converting light from one geometrical format to another. In particular, the described illumination converters are capable of converting a circular source such as an LED to a linear source useful in an edgelit waveguide, which can be used in a backlight for a display.
(FR)
L'invention concerne en général des convertisseurs d'éclairage qui permettent de convertir de la lumière d'un format géométrique à un autre. En particulier, les convertisseurs d'éclairage selon l'invention permettent de convertir une source circulaire, par exemple une DEL, en une source linéaire utile pour un guide d'ondes à éclairage latéral, qui peut être utilisé dans un rétroéclairage pour un écran.
