Abstract

La présente invention porte sur un élément de guidage de lumière (20) et sur un dispositif électronique (100) ayant l'élément de guidage de lumière (20). L'élément de guidage de lumière (20) comprend une colonne de guidage de lumière. La colonne de guidage de lumière comprend un premier corps de guidage de lumière (22) et un second corps de guidage de lumière (24) raccordé au premier corps de guidage de lumière (22). Le premier corps de guidage de lumière (22) est pourvu d'une surface d'entrée de lumière (2211) et d'une courbe réfléchissante (2231). Le second corps de guidage de lumière (24) est pourvu d'une surface de sortie de lumière (245). La surface d'entrée de lumière (2211) et la surface de sortie de lumière (245) sont disposées à distance l'une de l'autre. La courbe réfléchissante (2231) est raccordée entre la surface d'entrée de lumière (2211) et la surface de sortie de lumière (245). La surface d'entrée de lumière (2211) guide la lumière ambiante vers la surface de sortie de lumière (245) pour émettre la lumière ambiante vers l'extérieur. Dans le dispositif électronique (100), un capteur du dispositif électronique (100) est disposé à l'intérieur d'un boîtier (12) ; l'élément de guidage de lumière (20) s'étend à partir du bord d'un ensemble écran (14) jusqu'au capteur de telle sorte que l'élément de guidage de lumière (20) puisse guider la lumière ambiante vers un capteur de lumière (30) et que le capteur de lumière (30) ne puisse pas être intégré au bord de l'ensemble écran (14). Par conséquent, la largeur d'encadrement de l'ensemble écran (14) est réduite, ce qui facilite la conception de plein écran du dispositif électronique (100).
