Definitions
- the present invention relates to a laser unit for emitting a beam-of light, suitable to produce light effects.
- the first laser units had large generators, from which the beam was conveyed, by way of fiber-optic guides, to a reflecting element, by means of which it was possible to produce particular geometries of the emitted beam.
- Component miniaturization has currently allowed to produce compact laser generators, allowing their installation in movable units provided with actuation elements and eliminating the need for fiber-optic guides.
- the mobility of the unit leads to the possibility to direct the emitted beam at will, allowing to arrange and move in space the particular geometries given to the beam by the reflecting element.
- the generator emits the light beam, which is reflected, by means of a fixed mirror, toward the reflecting element, which can deflect it since it can be orientated within a certain rotation angle with respect to the inactive position.
- the resulting optical effect is no longer that of a single beam projected by the unit into the environment but that of a continuous plane which is the locus of the points successively and repeatedly occupied by the beam.
- the aim of the present invention is to obviate the above-mentioned drawbacks and meet the cited needs, by providing a laser unit for emitting a light beam that is suitable to provide light effects having a three-dimensional effect, i.e., capable of projecting solid figures in the environment in which it is installed.
- an object of the present invention is to provide a laser unit that is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
- the present laser unit for emitting a light beam suitable to provide light effects, comprising a laser generator, a mirror arranged along the direction in which the beam is emitted by said generator, and a station for the controlled deflection of the beam, all three components being rigidly mounted on a movable motorized base that allows to orientate the beam emitted by the generator, characterized in that said station comprises two elements for reflecting the light beam, which can move with respect to said base and can rotate about respective rotation axes.
- the reference numeral 1 generally designates a laser unit for emitting a light beam suitable to provide light effects.
- a footing 2 is rigidly coupled to, or rested on, a fixed surface, supports the entire unit 1 and is provided with sockets 3 for connection to a control unit, not shown in the figure; the footing 2 contains a servomotor 4, and a U-shaped support 5 is mounted on the shaft 4a of said servomotor, which can rotate about an axis that is _perpendicular to the resting plane of the footing 2.
- Two coaxial servomotors 6 are arranged inside the upper ends of the support 5, have a horizontal axis and are directed so that their protruding shafts face each other.
- the support 5 and the footing 2 constitute the base 7 of the unit 1.
- a box-like body 8 is suspended between the shafts of the servomotor 6 so that it can rotate rigidly with the shafts, and a laser generator 9 is provided inside the box-like body 8.
- the beam emitted by the generator 9 travels along a first portion 10 in a straight line, at the end of which it is deflected by 90° by a fixed mirror 11.
- the beam travels along a second portion 12, reaching two reflective elements 13, usually of the galvanometric type, which have a respective mirror-finished surface that is suspended on a respective orientable axis.
- the orientable axes of the two elements 13 are mutually perpendicular, and the rotations that can be imparted to the mirror-finished surface are such as to always keep the reflected laser beam within the mirror-finished surface.
- each element 13 is allowed to rotate through 45°, both clockwise and counterclockwise, about its own axis with respect to an initial configuration that corresponds to no rotation.
- the beam 14 projected into the environment is therefore comprised within a conical boundary surface 15 that has a semiaperture ⁇ of 45°, with an axis of symmetry that is perpendicular to the direction of the beam in the portion 12.
- the presence of the servomotors 6 allows to orientate the box-like body 8, and therefore also the boundary surface 15, by turning it through an angle ⁇ of up to 240°.
- the servomotor 4 instead allows to turn the support 5, about its axis of symmetry, through an angle ⁇ of up to 360°.
