Abstract

L'invention concerne un appareil de rétroéclairage à éclairage direct, qui présente une efficacité énergétique élevée avec moins de non-uniformité d'éclairage périodique. L'appareil de rétroéclairage à éclairage direct est doté d'une pluralité de sources lumineuses linéaires, d'une plaque de diffuseur de lumière, et analogues. La source lumineuse linéaire a un diamètre extérieur de 5 mm à 30 mm. Au moins une surface de lumière sortante ou une surface de lumière entrante a une structure irrégulière au moins en partie. La structure irrégulière, qui est une zone dans laquelle le diamètre extérieur de la source lumineuse linéaire est projeté verticalement sur la plaque du diffuseur de lumière, et la structure irrégulière, qui est une zone ayant la position intermédiaire des sources lumineuses linéaires adjacentes au centre et une largeur identique au diamètre extérieur de la source lumineuse linéaire, ont des formes différentes.
