A mirror assembly (10) including a dichroic mirror (50) which allows a predetermined narrow spectral band to pass through the mirror and be seen from aposition forward of the mirror (50), and which further reflects a broad spectral band of light which originates from a direction forward of the mirror; a light source (62, 76) is positioned rearwardly of the mirror (50) and emits light in the predetermined narrow spectral band passed by the dichroic mirror; and an electronic circuit is provided which is operable to step up, or step down the voltage supplied to the light source thereby maintaining a constant voltage source which is utilized to energize the light source (62, 76).
Ensemble de miroir (10) constitué des éléments suivants : un miroir dichroïque (50) conçu pour qu'une bande spectrale étroite puisse le traverser et être aperçue d'un point d'observation situé à l'avant du miroir (50) et pour refléter la lumière d'une bande spectrale large prenant son origine devant le miroir; une source de lumière (62, 76), placée derrière le miroir (50) et émettant un faisceau lumineux dans une bande spectrale étroite prédéterminée pour pouvoir traverser le miroir dichroïque; et un circuit électronique conçu pour élever ou abaisser la tension fournie à la source de lumière, de manière à conserver une source de tension constante pour alimenter la source de lumière (62, 76).
