Abstract

La présente invention concerne un réverbère à DEL. Le réverbère à DEL selon la présente invention comprend : un élément (100) de couvercle qui est fabriqué à partir d'un matériau en résine synthétique, comporte des nervures (111) servant à renforcer sa résistance mécanique et est muni d'une section (118) à pince sur un côté de telle façon que la section (118) à pince soit montée sur une structure (P) de réverbère ; un élément (200) de lampe qui est fabriqué à partir d'un matériau en résine synthétique et monté du côté inférieur de l'élément (100) de couvercle, et qui comporte une pluralité de sections (220) de lentilles montées suivant une pluralité de lignes, une section (230) de carte à circuit imprimé étant montée au niveau de chaque section de la pluralité de sections (220) de lentilles et munie de DEL (239) de 0,05 à 0,3 W suivant une pluralité de lignes, une pluralité de trous (212) d'évents étant formée pour la ventilation d'air extérieur, et des barrières (213) étant formées entre les trous (212) d'évents et la pluralité de sections (220) de lentilles de telle façon que l'humidité introduite par les trous (212) d'évents ne puisse être introduite du côté de la section (230) de carte à circuit imprimé ; et une section (250) de rayonnement qui est fabriquée à partir d'un matériau en résine synthétique et disposée du côté supérieur de l'élément (200) de lampe, et qui comporte un rebord (251) monté à l'extérieur des barrières (213) de telle façon que l'humidité introduite par les trous (212) d'évents ne puisse être introduite du côté de la section (230) de carte à circuit imprimé, la section (250) de rayonnement évacuant la chaleur générée à partir des DEL (239) de la section (230) de carte à circuit imprimé au moyen de l'air introduit via les trous (212) d'évents.
