CA 2730719

A lighting module includes a light output window, at least one side wall that defines a cavity and a mounting plate, and at least one light source such as a light emitting diode, and at least one reflector that is within the cavity. The light output window may be one of the side walls in a side-emitting configuration. The spectral distribution of the light that is the color or color temperature coming out of the light output window may be changed by manipulating the relative position of the side wall to the at least one reflector that is within the cavity such that more or less light is incident on a phosphor material.

Module d'éclairage, comprenant une fenêtre de sortie de lumière, au moins une paroi latérale délimitant une cavité et une plaque de montage, et au moins une source lumineuse, et au moins un réflecteur placé dans la cavité. La fenêtre de sortie de lumière peut être une des parois latérales dans une configuration à émission de lumière latérale. La distribution spectrale de la lumière émanant de la fenêtre de sortie de lumière peut être modifiée par manipulation de la position de la paroi latérale par rapport au réflecteur placé dans la cavité, de manière à augmenter ou diminuer la quantité de lumière incidente sur un matériau luminophore.
