Abstract

La présente invention concerne un module fluorescent (10), comprenant : un substrat (120) qui comprend une première surface (1201), la première surface (1201) étant pourvue d'une rainure (1202) ; et une couche de conversion de longueur d'onde (110) disposée dans la rainure (1202) et conçue pour convertir une lumière d'excitation incidente en une lumière excitée ayant une plage de longueurs d'onde différente de celle de la lumière d'excitation, puis l'émettre. La couche de conversion de longueur d'onde (110) comprend une surface d'incidence de lumière (1101) ; la longueur maximale de la couche de conversion de longueur d'onde (110) dans une direction parallèle à la surface d'incidence de lumière (1101) est supérieure à la longueur maximale dans la direction perpendiculaire à la surface d'incidence de lumière (1101) ; et une couche réfléchissante de lumière est disposée sur toutes les surfaces de la couche de conversion de longueur d'onde (110) à l'exception de la surface d'incidence de lumière (1101). Un couvercle réfléchissant (130) relié au substrat (120) recouvre la première surface (1201) depuis le dessus et entoure, conjointement à la première surface (1201), la couche de conversion de longueur d'onde (110) ; le couvercle réfléchissant (130) comprend une seconde surface (1301) proche d'un côté de la couche de conversion de longueur d'onde (110), et permet de réfléchir la lumière excitée incidente sur la seconde surface (1301) en retour vers la couche de conversion de longueur d'onde (110) ; et le couvercle réfléchissant (130) comprend en outre une première ouverture de passage de lumière ( 131) destinée à la transmission de la lumière excitée.
