Abstract

L'invention concerne un boîtier décodeur et sa structure de guidage de lumière et de protection contre la lumière. La structure de guidage de lumière et de protection contre la lumière du boîtier décodeur comprend un capot supérieur de boîtier décodeur pourvu d'une pluralité de trous de guidage de lumière. Un ensemble de protection contre la lumière servant à protéger contre la lumière est disposé au-dessous des trous de guidage de lumière. L'ensemble de protection contre la lumière et les trous de guidage de lumière sont formés d'un seul tenant et permettent d'obtenir, au moyen d'une structure fixée sur l'enveloppe du boîtier de décodeur, le même effet d'éclairage qu'une colonne de guidage de lumière traditionnelle et qu'un écran de protection contre la lumière traditionnel, ce qui permet de réaliser des économies sur le coût du développement des moules, le coût des pièces et le coût de la main-d'œuvre d'assemblage.
