Abstract

Cette invention porte sur un projecteur décoratif, conçu pour la projection, dans des conditions ambiantes sombres, de signes, de formes géométriques et de dessins en noir et blanc ou en couleurs, sur un fond de couleur claire. Le projecteur décoratif, dans sa première variante de construction, selon l'invention, est constitué par au moins une source de lumière (1), fixée à une surface (2) et alimentée par l'un des moyens connus, ainsi que par d'autres sources de lumière (3) disposées au-dessous d'une plaque de filtre (4) et à l'intérieur d'un filtre de lumière (5). La source de lumière (1) est apte à émettre dans une direction (a) croisant la plaque de filtre (4), et les sources de lumière (3) émettant de la lumière sur un plan (A - A) qui peut être parallèle à la surface (2). La deuxième variante du dispositif comporte plusieurs sources de lumière (8) disposées sur les génératrices d'une surface en forme de cône (B), et qui, du fait de leur position, enverront de la lumière sur un plan de projection (C) situé à l'extérieur de la zone constituée par un filtre de lumière (10) ; un plan de projection (C) pouvant être parallèle à une surface (7). La troisième variante du dispositif comporte au moins une paire de sources de lumière (D), fixées à une surface (11) et placées entre une plaque de filtre supérieure (12) et une plaque de filtre inférieure (13), ainsi qu'à l'intérieur d'un filtre de lumière (14). En dehors des trois variantes mentionnées ci-dessus, le dispositif peut également être proposé sous cinq autres variantes.
