Definitions
- the present invention relates to a projector particularly for projecting images in variable dimensions and in infinite colors.
- Conventional projectors used for example in the field of show business generally comprise a light source on the light beam whereof a filtering element is interposed in order to provide the intended coloring.
- the aim of the present invention is to eliminate the above-described drawbacks, by providing a projector particularly for projecting images in variable dimensions and in infinite colors which allows to obtain, with structurally simple means, an infinite range of colors, allowing to combine in the various shades the three complementary colors, i.e., cyan, magenta and yellow.
- an object of the present invention is to provide a projector which allows to vary at will the dimensions of the resulting image and to provide said variation continuously and simply.
- Another object of the present invention is to provide a projector which is particularly versatile and capable of combining the possibility of obtaining an infinite color range and of modifying the dimensions of the image and of combining their shape at will.
- Another object of the present invention is to provide a projector, particularly for projecting images in variable dimensions and infinite colors, which thanks to its particular constructive characteristics is capable of giving the greatest assurances of reliability and safety in use.
- a projector particularly for projecting images in variable dimensions and infinite colors which comprises, on a light beam emitted by a light source, a color changer, characterized in that said color changer is interposed between said light source and an image focusing unit.
- the projector particularly for projecting images in variable dimensions and infinite colors comprises a light source 2, constituted by a high-power discharge lamp which emits an unfocused light beam 3.
- a color changer Downstream of the source 2 there is provided a color changer, generally designated by the reference numeral 4, which is constituted by a mechanical system with six motors, two for each complementary color (cyan, magenta and yellow), and there is also provided a dimmer designated by the reference numeral 5; with this arrangement, an unfocused beam of light is projected onto the color changer.
- the color changer 4 has, for each complementary color, two sectors 10 which are arranged symmetrically with respect to each other and are provided with a central body 11 which can engage a rotation pivot 12.
- a toothed sector 13 is connected to the central body 11 and meshes with the gear 14 of a corresponding actuation motor.
- a glass plate 15 of the type capable of withstanding high temperatures and on which a portion is provided which is colored in a complementary color and in practice forms a dichroic film which is laser-etched so as to have a contour having a particular pattern.
- the colored portions 16 have a continuous covering layer 16a which has, on its edge directed toward the other sector, comb-shaped protrusions 16b.
- the sectors 10 can be interposed along the light beam 3 so as to produce a coloring which depends on the arrangement of the sector in the light beam.
- the comb-shaped protrusions of the two sectors are shaped complementarily, so that when the two sectors are completely mutually superimposed the light beam is completely colored, while the gradual spacing of the sectors causes the light beam, which is unfocused, to produce a coloring whose intensity decreases gradually as the sectors move apart, until they are mutually separated and therefore not interposed on the light beam.
- the presence of the dimmer allows to adjust the luminous output at will.
- the dimmer is provided by means of sectors which are shaped exactly like the above described sectors regarding the color changer, the only difference being that the two complementary sectors are constituted by sheet-like elements made of metal plate or the like which are optically black, so that it is possible to achieve a continuous variation in light intensity.
- the color changer is interposed between the light source and a focusing unit, generally designated by the reference numeral 21.
- An iris diaphragm and a rotating unit are arranged between the color changer and the focusing unit; the rotating unit is provided with a first gobo 23 and a second gobo 24, one for fixed images and one for rotating images, which can be selectively interposed on the light beam; correspondingly, the focusing unit 21 has a first doublet 22 which arranges itself so as to correspond with the iris diaphragm 20, and a second achromatic doublet 25 for focusing the gobos or masks 23 and 24.
- the iris diaphragm is motorized, and its internal laminas assume different diameters; when one of the contours (gobos) fitted on the wheels 23 and 24 is inserted on the optical plane, the iris diaphragm opens and the projected images is the projection of the contour of the gobo inserted in the light beam with the wheels 23 or 24.
- the lenses 22 and 25 are supported by a rotating disk 26 which can be actuated automatically in combination with the movement of the rotating assembly; moreover, the disk 26 can have a lens-free passage to obtain maximum luminous output, achieving particular effects.
- the rotating disk 26 can be actuated manually in order to obtain any combination of effects.
- a prism wheel 28 which can support rotating and fixed prisms and is also provided with a through opening in order to provide its functional disconnection.
- the zoom 30 comprises a first lens set 31 and a second lens set 32 in which the first set 31 has two double-convex lenses and the second unit has a double-concave lens.
- the sets 31 and 32 are slidingly mounted on a guide which is designated by the reference numeral 40.
- the first set is connected to a first belt 41 which is actuated by a first variation motor 42 of the step type, while the second set 31 is connected to a second belt 43 which is connected to a second variation motor 44 of the step type.
- the mutually independent actuation of the motors 42 and 44 causes, by means of the translatory motion of the corresponding belts 41 and 43, the sliding of the units 31 and 32 on the guiding bar 40, thus allowing to provide a zoom with a projection angle between 7 and 69 degrees.
- Another important aspect of the present invention is constituted by the fact that the projector has very small dimensions, thanks to the particularly sophisticated embodiment of the assembly.
- the materials employed, as well as the contingent shapes and dimensions may be any according to requirements.
