Definitions
- the present invention relates to a lighting device, capable of producing a halo of light colored in a homogeneous manner and adjustable both in intensity and in color.
- a particularly advantageous application of this device is that of scenic lighting, although, in general, any situation in which colored lighting is used can constitute an application of the present invention.
- the lights for cinematographic or photographic shots can also constitute an application of the invention.
- obtaining a particular coloration in a localized halo of light, combined with a determined intensity of light is usually done by bringing together on this halo several light beams uniformly colored each in a fundamental color, allowing, by appropriate dosage of these fundamental colors to obtain the desired shade of color.
- the relative dosage of the fundamental colors is done by the individual adjustment of the light intensity of each of the sources.
- these light sources usually spotlights, are spaced from each other, and are adjusted individually.
- Either the projectors are controlled remotely, using motors, electric for example, and the installation of such controls making it possible to adjust both their orientation and their light intensity is complex and expensive.
- the subjects to be lit are often mobile. They should therefore be followed by a simultaneous and appropriate orientation of the projectors. As these projectors are not placed in the same place, for reasons of space and mobility, the fact of following a mobile subject is a relatively complex task, especially when implementing a simultaneous remote control.
- the most advantageous solution for solving such a problem consists in producing the desired mixture of colors in a single projector, or, more generally, on the propagation path of a light beam.
- a projector comprising a light source, means for giving this light source a defined direction of propagation, thereby determining a beam, and means for adjusting the width, intensity and coloring of the beam.
- the coloring of the beam is done by interposition on the path of the latter of a plurality of colored filters, comprising in this case sheets of colored transparent material, known in the art under the name of " gelatins ", each colored filter being interposed on a more or less significant part of the surface of the cross section of the beam at the level of this filter.
- each filter in two moving parts according to a plane normal to the light beam, the two parts of each filter being able to totally meet in an extreme position, or on the contrary, take all the positions. intermediate to the other extreme position where they are separated so as no longer to interpose in the light beam.
- Document DE-A-1 804 980 (Niethammer) describes a projector more particularly for the scenic field.
- This projector has a number of colored filters to obtain a colored beam.
- the beam obtained has a uniform coloration for a limited number of colors.
- Halftone cannot be obtained because it would be necessary to use each partially colored filter for this, which is not possible without eliminating the homogeneity of the colored beam.
- the object of the present invention is to allow the homogeneous coloring of a halo of light coming from a lighting device, said halo being colored according to the shade sought, said shade being adjustable at will.
- Such a lighting device comprises a light source adapted to create a light beam, a reflective mirror disposed behind the light source and, in front of the light source, along the path of the light beam, successively and spaced from each other from said light source to the exit of the lighting device, at least one optical lens, an adjustable iris diaphragm, at least two optical lenses mounted for displacement relative to each other along the beam luminous and a plurality of colored filters, arranged spaced apart from each other, each of said plurality of colored filters comprising a pair of sheets of colored transparent material, called gelatins arranged so as to be placed partially or totally in the path of the light beam or outside of this, device characterized in that the light source is said to be wide and has electrodes whose l a length is greater than 6 mm, and in that said at least two optical lenses are arranged so that the image of the light source is focused on the farthest from said two lenses and that the light
- such a device is also characterized in that the lens closest to said wide source, immediately downstream thereof, is a so-called aspherical lens, of substantially conical shape with widely rounded tip, and one of which flat base is normal to the direction of propagation of the light beam is directed towards the source.
- the beam and by the same token the halo of light obtained with a device according to the invention, is colored uniformly.
- a device also comprises at least two lenses arranged downstream of said diaphragm, at least one of said two lenses of the plurality of lenses is axially movable, in the direction of propagation of the light beam, and a shutter means adjustable, opaque, consisting of two opaque plates, movable in a plane normal to the path of the light beam, can partially interpose on this path.
- Such arrangements allow adjustments to be made to the focus, the width of the light beam and the light intensity.
- the colored filters are each a pair of sheets of colored transparent material, called gelatins, which are each stretched respectively on a metal frame arranged in a plane normal to the path of the light beam, these frames being mobile in this plane so as to be able to approach where to deviate and thus partially or totally interpose said gelatins on the path of the light beam.
- a device comprises a shutter means, three colored filters, and an uncolored filter capable of blurring the light beam more or less.
- Such a device implemented in a projector, for example, therefore makes it possible, by the range of possibilities it offers, to considerably reduce the number of projectors to be used, and to improve the quality of the light halo without any other disadvantage .
- a headlamp 1 implementing a first embodiment of the invention described by way of example comprises a so-called wide light source 10 consisting of a glass bulb 13 substantially ovoid whose axis is disposed generally perpendicular to the general axis of the projector 1, Typically, such a bulb has an axial width of about 30 mm, and a circular cross section with a diameter of 25 mm.
- Two electrodes 11, 12 made up of filaments extend parallel to the axis of the bulb 13 inside of it.
- the axial dimension of these two electrodes, which constitute the light source proper, is greater than 6 mm.
- Such an axial dimension in practice determines the width of the light source. This is not, in this case, negligible compared to the dimensions of the different optical elements used in the invention and described below, the light source is said to be "wide".
- the bulb contains a halogen gas.
- the source is located near one of the closed ends thereof, the so-called upstream end.
- the opposite open end through which the light beam exits is said to be downstream.
- a substantially hemispherical reflector 14 On the axis of the headlamp 1, immediately upstream from the source 10, is arranged a substantially hemispherical reflector 14.
- the pole of this hemisphere is arranged in the axis of the projector, oriented upstream. In this way, the reflector 14 reflects the light radiation coming from the source 10 generally downstream.
- a lens 15 Downstream of the source 10, coaxially with the projector, is arranged a lens 15, called aspherical.
- a lens has a substantially frustoconical shape, the base of which would be normal to the axis of the headlamp 1 and the point of which, broadly rounded, would face downstream of the headlamp.
- annular diaphragm 16 of the iris type coaxial to the axis of the headlight 1, is arranged an annular diaphragm 16 of the iris type, having an annular opening 17 of adjustable diameter using appropriate adjustment means (not shown).
- a first lens 18 Downstream of the diaphragm 16 is arranged, coaxially, a first lens 18.
- Such a lens in the embodiment described, is generally convex, asymmetrical axially, and has a substantially planar face, upstream, and a convex face, substantially in the form of a portion of a sphere, facing downstream.
- a second lens 19, of a kind similar to the first, is arranged coaxially downstream of the latter at a distance adjustable by axial displacement of at least one of the two lenses 18, 19.
- these two lenses are axially movable and can be operated by suitable means known per se (not shown).
- the second lens 19 has a general diameter greater than that of the first, is also convex, asymmetrical axially, and has a substantially flat face turned upstream.
- a mirror image 51, 52 of the electrodes 11, 12 is formed at the level of the lens 19.
- a shutter means Between the lenses 18 and 19 is disposed, along a plane normal to the axis of the projector, a shutter means, or shutter 20.
- this shutter 20 is disposed substantially at mid-axial distance between the two lenses 18, 19 .
- This shutter 20 consists of two rectangular plates 21, opaque, metallic for example, rigidly mounted on supports 22 capable of sliding on a slide 23, for example formed of two parallel rails.
- the slide 23 is arranged in a direction perpendicular to the axis of the projector, slightly away from this axis.
- the axis of the projector cuts the median of the plates 21 parallel to the slide 23.
- Downstream of the lens 19 are arranged substantially along planes normal to the axis of the headlamp, and in axially equidistant succession, four filters 25 25 ', 25 ", 25"'.
- the identical elements described carry, from one filter to another, the same reference numerals to which are added the symbols (, ',' ',' '') to identify their belonging to the filters carrying the same symbols respectively.
- the filter 25 comprises two U-shaped frames 26, 27, asymmetrical in that one of the branches of the U is larger than the other, these two frames being identical, arranged head to tail in two parallel planes very slightly apart so to allow these two executives to partially overlap with negligible play.
- the two frames 26, 27 are in fact substantially arranged facing each other, so that, when they are partially superimposed, the ends of the branches of the frame 26 partially cover the ends of the two branches of the frame 27, the frame 26 being arranged the further downstream.
- the frames 26 and 27 are respectively mounted on supports 28 and 29, capable of sliding on a slide 30.
- This slide 30, similar to the slide 23 of the shutter, is, for example, made up of two parallel rails.
- the slide 30 is, in the general plane of the filter 25, normal to the axis of the projector, perpendicular to the direction of the slide 23.
- This direction can be defined as being horizontal, the slide 23 being vertical, this being of course relative to the direction of the headlight axis which is, in this case, horizontal.
- Two stops 31 are arranged at each end of the slide 30, in order to limit the movement of the supports 28, 29.
- Such a clearance thus determines the displacement of the frames, which can be separated from one another, or, on the contrary, brought together until a slight overlapping of the ends of their branches, overlapping limited by the abutment of the two supports 28, 29 against each other.
- gelatins have the shape of a rectangular trapezoid, so as to cooperate with the unequal branches of the U formed by each of the frames, and are, like these frames, arranged upside down so that their biased edges 34, only edges not integral with the frames, are parallel.
- the edges 34 are also separated, and the space 35 separating them is crossed in its middle by the axis of the projector.
- the filter 25 is then in the so-called open position.
- the supports 28 and 29 are in abutment against each other the gelatins 32 and 33 overlap in partial superposition in a determined narrow band, brought in a single plane, by an edge 34 and the projection in an axial direction of the other edge 34 in the same plane.
- This superimposition is made as narrow as possible, and in fact serves as a safety margin to ensure that when the filter 25 is in this position, called closed, the gelatins 32 and 33 are necessarily crossed by the axis of the projector. r.
- Gelatins 32 and 33 are of the same nature and the same color.
- the gelatin filters 25, 25 'and 25 "have a smooth surface and are of three different colors, preferably complementary.
- gelatins 32 '"and 33"', of the filter 25 "" are colorless and of grainy surface, such gelatins being able to blur the outline of a light beam which passes through them.
- the supports 22 of the shutter, the supports 28 and 29 and their correspondents of the other filters, are controlled in their deflections on their respective slides by suitable control means, advantageously servo motors with programmable control. Such means are not shown in the figures.
- FIGS 3 and 4 show an alternative embodiment of the invention, in which the elements already described in the first embodiment bear the same reference numerals.
- hemispherical reflector 14 From upstream to downstream, there is a hemispherical reflector 14, a wide source 10, and an aspherical lens 15.
- a second lens 36 of convex asymmetrical shape, is arranged coaxially downstream of the aspherical lens 15.
- an optical focusing device 37 Downstream, coaxially with these elements, there is an optical focusing device 37.
- Such a device comprises a substantially cylindrical body 38, a first set of lenses mounted coaxially in succession 39, 41, and a second set of lenses 42, 43 also mounted coaxial in succession, the second set being axially movable relative to the first.
- An annular support ring 44 extending radially from the cylindrical body 38, makes it possible to subject the device 37 to the projector.
- a mirror image 51, 52 of the electrodes 11, 12 is formed at the level of the lens 43.
- ZOOM Such a device, known per se, is commonly called "ZOOM” and is in widespread use in photography as in stage lighting.
- the shutter 20 is located downstream of the "ZOOM" 37, immediately upstream of the cascade of filters 25 25 ', 25 "and 25"'.
- the shutter 20 and the filters 25, 25 ', 25 "and 25"' are identical to those used in the first embodiment described.
- the reflector 14 partly reflects the light radiation emitted by the wide source 10 downstream, another part of this radiation going directly in this direction.
- the role of the reflector 14 is to allow all of the radiation to go downstream from the projector.
- the axis of the projector is the general direction of propagation of light radiation, which thus forms a beam.
- the light beam passes through the diaphragm 16 which determines, through its opening 17, and in a proportional manner, the diameter of this beam once it has left the projector.
- the axially movable lenses 18, 19, in the first embodiment, or the "zoom" 37, in the second embodiment of the invention, are used to focus the image, here a simple circle whose sharpness is defined by the outline.
- the shutter 20, located either between the lenses 18, 19, or downstream of the "ZOOM" 37, has the function of adjusting the light intensity.
- the filters 25, 25 'and 25 "more or less color this light beam downstream of the shutter, the gelatins being capable of deviating sufficiently when the filter is in the open position so as not to be in the path of this beam .
- the blurring which can be sought for certain particular applications must not, if a homogeneous mixture of colors is to be obtained, result from a focusing defect.
- the 25 "filter, fitted with granular surface gelatins, makes it possible to obtain a blurred contour beam from a correctly developed beam.
- the blurred nature of the beam, and consequently of the halo which it projects, can be a desired effect in certain productions.
