Abstract

Un feu comprend une pluralité de sources de lumière (42, 52) disposées en parallèle, une lentille de projection à travers laquelle de la lumière émise par la pluralité de sources de lumière (42, 52) est transmise, et un premier réflecteur entre sources de lumière (31c, 32c) et un deuxième réflecteur entre sources de lumière (31d, 32d) qui sont disposés de façon à enserrer une ligne reliant les sources de lumière (42, 52) adjacentes l'une à l'autre et qui sont configurés pour réfléchir une partie de la lumière émise par les sources de lumière (42, 52) vers la lentille de projection.
