Abstract

L’invention concerne un dispositif optique pour un dispositif lumineux permettant de créer des effets de lumière, comprenant  un support (2), une surface réfléchissante (1), ledit support (2) comprenant un disque (21) pourvu sur une face d’une paroi circulaire (22) se dressant en saillie depuis ladite face et définissant un manchon (23) coaxial avec l’axe central (A) du disque (21), un élément porteur (4) de la surface réfléchissante (1) étant agencé pour être logé dans le manchon (23) de sorte qu’un faisceau lumineux (F) entrant par l’extrémité ouverte du manchon (23) est réfléchi par la surface réfléchissante (1) pour sortir par un orifice de sortie (25) ménagé dans la paroi (22) du manchon (23) pour être en regard de ladite surface réfléchissante (1), un deuxième orifice (26) étant ménagé dans la paroi (22) du manchon (23) sensiblement à l’opposé de l’orifice de sortie (25), caractérisé en ce que, lorsque le matériau constituant le support (2) présente une densité inférieure à 3200kg/m3, le support (2) présente au moins un orifice (27) ménagé sur la partie du disque (21) du côté de l’orifice de sortie (25), lorsque le matériau constituant le support (2) présente une densité comprise entre 3200kg/ m3 et 3800kg/ m3, le disque (21) du support est sans orifice; et lorsque le matériau constituant le support (2) présente une densité supérieure  à   3800kg/m3,  le support (2) présente au moins un orifice (27’) ménagé sur la partie du disque (21) du côté de l’orifice (26) opposé à l’orifice de sortie (25).The invention relates to an optical device for a luminous device for creating light effects, comprising a support (2), a reflecting surface (1), said support (2) comprising a disc (21) provided on one side with a circular wall (22) protruding from said face and defining a sleeve (23) coaxial with the central axis (A) of the disc (21), a carrier element (4) of the reflecting surface (1) being arranged to be housed in the sleeve (23) so that a light beam (F) entering through the open end of the sleeve (23) is reflected by the reflecting surface (1) to exit through an outlet (25) provided in the wall (22) of the sleeve (23) to be facing said reflecting surface (1), a second orifice (26) being formed in the wall (22) of the sleeve (23) substantially opposite to the outlet orifice (25), characterized in that, when the material constituting the support (2) has a density of less than 3200k g / m3, the support (2) has at least one orifice (27) formed on the part of the disc (21) on the side of the outlet orifice (25), when the material constituting the support (2) has a density between 3200kg / m3 and 3800kg / m3, the disc (21) of the support is without orifice; and when the material constituting the support (2) has a density greater than 3800 kg / m3, the support (2) has at least one orifice (27 ') formed on the part of the disc (21) on the side of the orifice (26 ) opposite the outlet (25).
