Abstract

La présente invention concerne un abat-jour qui présente des tuyaux d'air et un appareil d'éclairage l'utilisant, un ou plusieurs tuyaux d'air étant agencés de façon à dissiper efficacement et rapidement la chaleur générée par un module d'émission de lumière, de façon à prolonger la durée de vie et à améliorer l'avantage économique de l'appareil d'éclairage. Dans ce but, un ou plusieurs tuyaux d'air sont agencés au niveau de la surface interne de l'abat-jour, de telle sorte que les tuyaux d'air peuvent être en communication avec l'air externe. La surface externe de chaque tuyau d'air est traitée de façon à réfléchir la lumière émise par une source de lumière, et présente une forme polygonale. Les tuyaux d'air peuvent être attachés à l'abat-jour et détachés de celui-ci. L'appareil d'éclairage à diodes électroluminescentes utilisant l'abat-jour selon la présente invention possède un cadre de dissipation de la chaleur dont une partie d'émission de lumière est formée au niveau d'une surface latérale de celui-ci. La surface latérale et/ou une surface inférieure du cadre de dissipation de chaleur présente un ou plusieurs trous de liaison de tuyau d'air, de telle sorte que de l'air externe est introduit dans le cadre de dissipation de chaleur à travers les tuyaux d'air de l'abat-jour de façon à dissiper la chaleur générée par le module d'émission de lumière.
