Title
(EN) LED LUMINAIRE USING LOUVERS AS A HEAT SINK
(FR) LUMINAIRE À DIODE ÉLECTROLUMINESCENTE UTILISANT DES ÉCRANS COMME DISSIPATEUR DE CHALEUR
Abstract
(EN)
An illumination system (10) comprising at least one light source (2), a heat sinking structure (5) on which the light source is arranged, said structure facilitating dissipation of heat from said light source and being at least partly light-transmissive and at least one reflector (3) arranged for reflecting light emitted by said light source, said reflector being arranged in the light emitting direction of the light source and configured to reflect incident light in a direction towards said heat sinking structure.
(FR)
L'invention porte sur un système d'éclairage (10), qui comprend au moins une source de lumière (2), une structure de dissipation de chaleur (5) sur laquelle est disposée la source de lumière, ladite structure facilitant la dissipation de chaleur à partir de ladite source de lumière et transmettant au moins partiellement la lumière, et au moins un réflecteur (3) agencé pour réfléchir la lumière émise par ladite source de lumière, ledit réflecteur étant disposé dans la direction d'émission de lumière de la source de lumière et configuré pour réfléchir la lumière incidente dans une direction dirigée vers ladite structure de dissipation de chaleur.
