Description

Laser assembly

The present application claims priority of German patent application DE 10 2014 207 051.1, the content of which is incorporated herein by reference.

The invention relates to a laser assembly with a laser device for generating three-dimensional or 3D light objects in a volume containing a scattering medium. Such laser devices are known from public prior use. These generally either have a complicated design or lack effect.

A laser device for generating three-dimensional light objects in a volume containing a scattering medium is known from DE 10 2006 044 989 Al . US 4,227,776 describes a rotating structure, through which a laser output beam is directed. EP 1 666 189 A 1 describes a laser processing device with a laser beam guidance device. EP 1 477 730 A2 describes a laser unit for emitting a laser beam, which unit is suitable for creating light effects. The object of the invention is to provide a laser assembly which is capable of creating sensational three-dimensional light effects in a simple manner in terms of design. Furthermore, the laser assembly should be particularly easily adaptable, in particular to local conditions, and versatile. This object is achieved according to the invention by the features stated in independent claim 1. The essence of the invention is that the laser assembly comprises a laser device and a laser device support frame. The support frame is capable of supporting the laser device. The laser device is movable with respect to support frame. For example, the laser device can be adjusted, such as pivoted and/or displaced, with respect to the support frame. It is advantageous for the laser device, in particular in an unlocked state, to be detachable or removable from the support frame. Preferably, the laser device can be lifted upwards out of the support frame. The laser device is advantageously also fully operational without the support frame. The movability of the laser device with respect to the support frame, in particular a pivoting capability of the whole laser device with respect to the support frame, creates a further degree of freedom in determining a location where the desired light effects are to be formed. An angle of the axis of rotation, about which the first deflector is rotatably drivable, to a level base can be specified by means of this movability of the laser device with respect to the support frame. Alternatively or additionally, a distance of the axis of rotation and a distance of the first deflector to the surface can be predetermined.

It is advantageous for the laser device to comprise a laser device housing. The laser device housing is advantageously intrinsically rigid. It is expedient for the laser device housing to have two side walls opposite one another. The side walls are preferably panel-like and extend in parallel with one another. In particular, in the simplest design of the laser device, a three-dimensional double cone with a variable cone angle can be created. In particular, attractive three-dimensional light effects can be created, which can be used, for example, in laser show technology. The scattering medium is in particular air. Fog or smoke are also possible as the scattering medium.

It is advantageous for the laser device to comprise a laser light safety device (not shown). In particular, the laser light source is only exposed and only emits a light beam when the rotor, which can be constructed in particular as a carrier disc, rotates at more than 500 revolutions per minute or is activated by a scan safety device. The laser device advantageously has at least one oscillation sensor. It is advantageous for the drive of the rotor to be switched off or for it to switch off when an oscillation or vibration detected by the oscillation sensor on the laser device exceeds a preset oscillation value. It is expedient for the laser device to have a drive safety device. If, for example, the rotor along with the shaft slips at least partially out of the housing of the rotor drive, a connecting lead is disconnected, such that the rotor drive is without a power supply and comes to a stop. The drive safety device effectively forms a shear safety device.

Further advantageous embodiments of the invention are stated in the dependent claims.

The embodiment according to dependent claim 2 provides an extremely stable support frame. It is expedient for the base to lie in a plane that preferably extends horizontally when the support frame is arranged as intended. For example, the base is formed by feet and/or an underneath of the support frame. The laser assembly according to dependent claim 3 forms a particularly versatile laser device. For example, the laser device, which has been taken out of the support frame, can preferably be suspended without the support frame on a ceiling, a gantry, a mast or such like. It is advantageous for the laser device to have at least one suspension means for this purpose, such as an opening, a protrusion, a hook or similar. The rotor preferably extends substantially horizontally in the suspended state of the laser device and then advantageously forms a lower part of the laser device. According to dependent claim 4, the laser assembly has at least one coupling device for the detachable arrangement of the laser device in the support frame, the at least one coupling device comprising in each case a first coupling means arranged on the laser device and a second coupling means connected to the support frame as well as a coupling means locking device. It is advantageous for two opposing coupling devices to be present.

The coupling device can facilitate a quick detachment of the laser device from the support frame. The coupling device can be constructed such that a disconnection of supply lines of the laser device, in particular power and control lines, is also possible by means of the coupling device.

Disconnection of coolant pipes, which may be present, is also possible by means of the coupling device.

The second coupling means can be directly or indirectly connected to the support frame.

The first coupling means is advantageously constructed as a coupling pin. The coupling pin preferably protrudes laterally outwards from the laser device housing. In particular, it is cylindrical. It is advantageous for the coupling pin to have at least one lead-in chamfer on its free end. An outwardly open locking receptacle is preferably arranged in the coupling pin. It is expedient for the second coupling means to be constructed as a coupling receptacle to at least partially accommodate the coupling pin. The second coupling means is advantageously designed to complement the first coupling means for this purpose. The coupling receptacle is preferably closed around its circumference.

The embodiment according to dependent claim 6 provides an extremely secure coupling device.

It is expedient according to dependent claim 7 for the two clamp parts of the locking device to fully encompass the first coupling means together in their closed position. The clamp parts of the locking device can

advantageously be connected firmly to one another by at least one coupling means locking device arrangement on the first coupling means. It is advantageous for this purpose for the at least one coupling means locking device arrangement to in each case have a locking bolt passing through the locking clamp parts and a locking nut that can be screwed onto the respective locking bolt.

The embodiment according to dependent claim 9 allows for a particularly simple and secure local adjustment of the laser device.

According to dependent claim 12, the laser assembly has at least one pivot bearing device, which comprises in each case a first bearing part arranged on the support frame and a second bearing part connected to the laser device, it being possible to pivot the first bearing part and the second bearing part relative to one another.

The first bearing part is advantageously constructed as a bracket, which has a bearing receptacle. It is advantageous for the second bearing part to be a bearing pin, which is constructed in a complementary manner to the bearing receptacle and is pivotally mounted therein. The second bearing part can be connected directly or indirectly to the laser device. According to dependent claim 13, the laser device can be pivoted manually, that is by hand. Alternatively, there is at least one pivot drive or motor to pivot the laser device with respect to the support frame.

According to dependent claim 14, there is at least one hollow-shaft drive to rotatably drive the rotor. Such a drive can be accommodated in an extremely compact manner. Furthermore, it is characterised by its high degree of functional reliability.

As a result of the embodiment according to dependent claim 15,

particularly attractive three-dimensional light effects can be created. Such a pivot drive can have a signal connection to a control device of the laser device to create three-dimensional light objects.

The individually controllable scanner devices can also be the subject of an independent invention when they are detached from the support frame to support the laser device. Accordingly, a laser assembly comprises a laser device to generate three-dimensional light objects in a volume containing a scattering medium. The laser device in turn comprises a laser light source to emit a light beam of visible light and a first deflector that can be rotatably driven about an axis of rotation, the axis of rotation passing through an optical deflector surface of the first deflector and the first deflector being arranged such that the axis of rotation coincides with the beam direction of an incidence portion of the beam, which portion impinges on the first deflector. In addition, the laser device has two second deflectors arranged at a distance from the axis of rotation, such that these can be impacted by at least one deflection portion of the beam, the second deflectors deflecting the at least one deflection portion of the beam to generate an output portion of the beam to create a three-dimensional light object. Each second deflector has a scanner device, which acts together with a control device and by means of which the respective second deflector can be tilted oscillating about a first tilting axis, the first deflector and the second deflector being arranged on a rotatably drivable rotor, the rotational axis of symmetry of which coincides with the axis of rotation. The second deflectors can be operated independently of one another by independent scanner devices. The control device can be constructed such that scanning movements of the deflector or the deflectors are synchronised with a rotational movement about the axis of rotation. This synchronisation can be such that a divergence of a scanned position of a deflector, when the deflector has performed a half or even a full revolution about the axis of rotation, is equivalent to a predetermined divergence nominal value. In particular, as a result of this, stationary 3D light objects or such objects that change slowly or at a predetermined speed can be created. Preferred embodiments of the invention are described hereinafter by way of example with reference to the accompanying drawings, in which:

Fig. 2 is a side view of a second embodiment of a laser assembly

Fig. 3 is a view from the direction III in Fig. 2, a detailed view of a pivot bearing device of the laser assembly shown in Fig. 1 and 2, and

Fig. 5 is a detailed view of a coupling device of the laser assembly shown in Fig. 1 and 2.

A laser assembly according to a first embodiment shown schematically in Fig. 1 has a laser device 1 to create three-dimensional light objects in a volume or space containing a scattering medium. The three-dimensional light objects are formed by scattering an output portion 3 of the beam moving transversely to an output beam direction 2 on the scattering medium, which is, in particular, air or a scattering mist or smoke.

A laser light source 4 of the laser device 1 emits a light beam 5 of visible light. In the example of the laser device 1 according to Fig. 1 , the light beam 5 is green light, which was generated for example by frequency doubling an Nd laser. The laser light source 4 is in particular a solid state laser, for example a diode -pumped solid state laser. The laser light source 4 is preferably constructed such that it is capable of creating the three basic colours of the visible spectrum, i.e. red, green and blue and to blend these colours according to requirements by addition to make all possible visible colours. A portion 7 of the beam of the light beam 5 impinging on a first deflection mirror 6 as an example of a first deflector is described hereinafter as an incidence portion 7 of the beam.

The first deflection mirror 6 can be rotatably driven about an axis of rotation 8 by a drive (not shown in Fig. 1). The axis of rotation 8 extends in parallel with the z-axis of a Cartesian x-y-z coordinate system shown in Fig. 1. The z-axis extends to the left in Fig. 1 , the x-axis upwards and the y-axis into the plane of the drawing. The axis of rotation 8 passes through an optical deflection surface 9 of the first deflection mirror 6 and coincides with a beam direction of the incidence portion 7 of the beam. The incidence angle of the incidence portion 7 of the beam onto the deflection surface 9 is 45°. Deflectors other than deflection mirrors are possible, for example deflection prisms. A second deflection mirror 10 is arranged at a distance from the axis of rotation 8. A deflection portion 1 1 of the beam impacts said mirror and is deflected by the second deflection mirror 10 to generate the output portion 3 of the beam to create the three-dimensional light object. The second deflection mirror 10 has a scanner device which is not shown in Fig. 1 and works with a control device, which is likewise not shown. The second deflection mirror 10 can be tilted with said scanner device in an oscillating manner about a first tilting axis y', which extends in parallel with the y axis in the present position of the second deflection mirrors 10 as shown in Fig. 1 and on which a point of impact 12 of the deflection portion 1 1 of the beam on a deflection surface 13 of the second deflection mirror 10 lies. The angle of incidence of the deflection portion 1 1 of the beam is less than 45° and can be adjusted using the scanner device. In the present position of the second deflection mirror 10 as shown in Fig. 1, the angle of incidence is about 32°.

The two deflection mirrors 6, 10 are arranged on a rotor 14 which can be rotatably driven with the aid of a drive (not shown) and the rotational axis of symmetry of which coincides with the axis of rotation 8. The rotor 14 can be constructed as a carrier disc. The carrier disc 14 is circular. It has a central through-opening 15. Said opening aligns with a through-opening 16 in a guide tube 17, which is turned away from the first deflection mirror 6 and is placed centrally on the carrier disc 14, through which guide tube the incidence portion 7 of the beam is guided. The guide tube 17 and the carrier disc 14 are connected to one another in a rotationally engaged manner. The drive is constructed as a hollow-shaft drive.

Because of the scanning movement of the second deflection mirror 10, the output portion of the beam 3 can be deflected across an angle range a between beam directions 18, 19, which are indicated with dashed lines in Fig. 1.

When the laser device 1 is being operated, due to the rotation of the carrier disc 14 about the axis of rotation 8 with the deflection mirrors 6, 10 fixed thereto, a double cone is generated in the shown angular position of the second deflection mirror 10, the circular base of said double cone being defined by the rotating point of impact 12 of the deflection portion 1 1 of the beam on the deflection surface 13 of the second deflection mirror 10 and said cone having a neck in a region 20, i.e. in the extension of the axis of rotation 8 into the volume in which the 3D light object is being created. The neck 20 is the intersection between the abutting apices of the cones of the double cone. By varying the angle of deflection by scanning the second deflection mirror 10 about the y'-axis inside the angular range a, the cone angle of the created double cone and the distance of the neck 20 from the first deflection mirror 6 is varied. On this basis, the double cone is created, as long as the scattering medium scatters the output portion of the light beam 3. In this way, a symmetrical or an asymmetrical double cone can be created in relation to a plane of symmetry in which the neck 20 lies and on which the axis of rotation 8 is located vertically.

As a result of the interaction of various drive speeds of the drive of the carrier disc 14 and thus various revolutions of the carrier disc 14 with corresponding controls of the y-scanner of the second deflection mirror 10, optically appealing, attractive 3D effects can be achieved.

In addition, the laser device 1 has a housing 21 , which comprises two side walls 22 opposite one another and connecting elements (not shown) which connect said walls to one another.

The laser light source 4 and the guide tube 17 as well as the drive of the carrier disc 14 are arranged inside the housing 21. The carrier disc 14 itself is located outside of the housing 21. The portion 7 of the beam extends substantially in parallel with the side walls 22 and roughly centrally therebetween.

Furthermore, the laser assembly has a support frame 23 for supporting the laser device 1. The support frame 23 has a foot part 24 with a flat base 25 facing downwards to securely support it with respect to a surface or ground 26 and two stand devices 27, which protrude vertically upwards from the foot part 24. The foot part 24 is, for example, plate-shaped or has a plurality of foot elements, which are then put together advantageously in the manner of a frame. The side walls 22 extend substantially vertically and in parallel with one another when the laser device 1 is arranged as intended in the support frame 23. The laser device 1 is located between the stand devices 27. Two suspension openings 30 are provided on each side wall 22

substantially opposite the carrier disc 14. The laser device 1 can be suspended using the suspension openings 30. The support frame 23 is preferably removed to do this. The laser device 1 can be lifted out of the support frame 23. There are two coupling device for this purpose, which are described in more detail below in particular with reference to Fig. 5.

In order to arrange the laser device 1 such that it can pivot with respect to the support frame 23, two pivot bearing devices 28 are provided, which are described in more detail below in particular with reference to Fig. 4. Each pivot bearing device 28 facilitates a pivoting of the laser device 1 about a common horizontal pivot axis 29 with respect to the support frame 23. The laser device 1 can be pivoted fully about the pivot axis 29.

The second embodiment of the laser assembly is described hereinafter with reference to Fig. 2. This again has a laser device 1 to generate three- dimensional light objects in a volume containing a scattering medium. Components, which are equivalent to those described above with reference to Fig. 1 , bear the same reference numerals and are not discussed again in detail. Reference is made to the preceding description. The laser light source 4 is arranged underneath the guide tube 17 in the embodiment according to Fig. 2. The light beam 5 emitted by the laser light source 4 according to Fig. 2 is initially deflected by 90° by each of two pre-deflection mirrors 31, 32. In this way, the incidence portion 7 of the beam is generated. The point and direction of the incidence portion 7 of the beam are adjustable precisely by the pre-deflection mirrors 31, 32.

A hollow shaft (not shown) of the hollow-shaft drive 33 grips the guide tube 17 directly or indirectly. The guide tube 17 and the carrier disc 14 are connected to one another in a rotationally engaged manner. For this reason, the guide tube 17 is mounted axially/radially inside the housing 21. The hollow-shaft drive 33 is also accommodated inside the housing 21.

Moreover, the laser device 1 has a detector/control unit 34. This has a position sensor (not shown in detail) which, by means of a control apparatus of the detector/control unit 30, serves to determine the angle of rotation position of the guide tube 17 in the housing 21 and thus to determine the angular position of the carrier disc 14 and the deflection mirror arranged thereon. The position sensor is preferably constructed as an inductive or optical position sensor. In the embodiment according to Fig. 2, instead of one single deflection mirror 10, two second deflection mirrors 10a, 10b are provided, which are arranged at a distance from the axis of rotation 8 and the angular positions of which are offset by 180° from one another in relation to the axis of rotation 8 (cf. Fig. 3). In the embodiment according to Fig. 2, the first deflection mirror 6 is constructed as a roof edge mirror with a roof edge angle of 90°, the incidence portion 7 of the beam impinging on a roof edge 35 of the first deflection mirror 6 such that an upper half in Fig. 2 of the incidence portion 7 of the beam is deflected upwards by 90° and a lower half in Fig. 2 of the incidence portion 7 of the beam is deflected

downwards by 90°.

This deflection is such that both of the second deflection mirrors 10a, 1 Ob are each impacted by the half of the cross section of the portion of the incidence portion 7 of the beam assigned thereto via the respective deflection surface portion 9 of the first deflection mirror 6.

Each of the two second deflection mirrors 10a, 10b has a scanner device 36, with each of which an oscillating scan tilt of the two second deflection mirrors 10a, 10b is possible about two axes x', y', which are perpendicular to one another and which lie in the xy plane, by a specific angular range. In the present position of the second deflection mirrors 10a, 10b shown in Fig. 2, the x'-axis extends in parallel with the x-axis and the y'-axis extends in parallel with the y-axis of the Cartesian x-y-z-coordinates system of the laser device 1. The second, i.e. the y-scanner device of the second deflection mirror 10 also has a signal connection to the detector/control unit 34.

Each of the two scanner devices 36 has an x'-drive motor 37 and a y'-drive motor 38. The two drives 37, 38 are each controlled by a scanner driver 39, which in turn has a signal connection to the detector/control unit 34.

Independent tilting of the second deflection mirrors 10a, 10b about the x'-, y'-axes during the rotation of the carrier disc 14 about the axis of rotation 8 is possible by means of the scanner driver 39. In particular, the scanner devices 36 of the deflection mirrors 10a, 10b can be controlled

independently of one another such that the deflection mirrors 10a, 10b can also be adjusted or operated independently of one another. Various working methods or embodiments of the detector/control unit 34 to generate three-dimensional light objects or 3D light effects are possible. The detector/control unit 34 is advantageously constructed such that in an operating mode of the laser device 1 , the scanning movements of the at least one deflection mirror 10; 10a, 10b are synchronised with a rotational movement about the axis of rotation 8 such that the divergence of the scan position of the second deflection mirror 10; 10a, 10b from the scan position of the second deflection mirror 10; 10a, 10b when it has performed a full revolution about the axis of rotation 8 is equivalent to a predetermined divergence nominal value. As a result of this, stationary 3D light objects or such objects that change slowly or at a predetermined speed can be created.

In the laser device 1 according to Fig. 2 and 3, an operating mode of the detector/control unit 34 is also possible, where the scan movements of the two deflection mirrors 10a, 10b are synchronised with their rotational movement such that the divergence of the scan position of one second deflection mirror 10a from the scan position of the other second deflection mirror 10b when the second deflection mirror 10a is in the angular position of the other second deflection mirror 10b after a half revolution is equivalent to a predetermined divergence nominal value. As a result of this too, stationary 3D light objects or such objects that change slowly or at a predetermined speed, and therefore attractive 3D light objects, can be created. The laser device 1 here again has a housing 21 , which supports in particular the laser light source 4, the pre-deflection mirrors 31, 32, the guide tube 17, the hollow-shaft drive 33 and the detector/control unit 34. The carrier disc 14 is located outside of the housing 21.

The support frame 23 again supports the laser device 1. The laser device 1 can be pivoted about the pivot axis 29 by means of the pivot bearing devices 28. The two pivot bearing devices 28 are described in more detail hereinafter in particular with reference to Fig. 4. The two pivot bearing devices 28 are identical such that substantially only one pivot bearing device 28 is described hereinafter.

As can be seen in Fig. 4, each stand device 27 supports, preferably on the top, two brackets 40 with bearing receptacles 41 that align with one another. In the bearing receptacles 41 of the respective pivot bearing device 28 a cylindrical bearing pin 42 is accommodated, the diameter of which complements the respective diameter of the bearing receptacles 41. The bearing pin 42 can be pivoted with respect to the brackets 40. The pivot axis 29 is determined by the brackets 40.

Each bearing pin 42 is directly connected to an adjacent support plate 43. Preferably, the bearing pin 42 and the respective support plate 43 are firmly connected to one another axially. Preferably, the bearing pin 42 and the assigned support plate 43 can be pivoted relative to one another.

Opposite the respective adjacent bearing pin 42, each support plate 43 has a central cylindrical coupling receptacle (not shown). A complementary coupling pin 44, which protrudes outwards from the adjacent side wall 22, engages in each coupling receptacle in the coupled position. Each coupling pin 44 aligns substantially with the adjacent bearing pin 42. It is advantageous for the coupling pins 44 to be fixed to the side walls 22 such that they cannot move. The coupling pins 44 also align with one another. Each coupling pin 44 is encompassed by a locking device 45 in a closed position of a locking device 45, which in turn comprises a first locking clamp part 46 and a second locking clamp part 47 as well as at least one locking bolt 48 and a locking nut 49 screwed onto the respective locking bolt 48. The at least one locking bolt 48 passes through the first locking clamp part 46 and the second locking clamp part 47 in a substantially secant manner. The head 50 of the respective locking bolt 48 directly or indirectly acts on one of the locking clamp parts 46, 47, while the respective locking nut 49 acts on the other locking clamp part 47, 46. The locking clamp parts 46, 47 are thus held together and cannot be moved relative to one another. In the closed position of the locking device 45, removal of the laser device 1 from the support frame 23 is impossible.

By unscrewing the respective locking nut 49, the locking clamp parts 46, 47 can be separated from one another, which then also ultimately allows for removal of the laser device 1 from the support frame 23. The locking device 45 is then in its open position.

The laser device 1 can be supplied with power, control signals and if appropriate, coolant, independently of the support frame 23. Alternatively, such supply can also be provided via the support frame 23. In this case, supply lines can be arranged, for example, in the stand device 27 or on the stand device 27. The coupling device can then be constructed such that the supply lines are also coupled thereby such that when the laser device 1 is detached from the support frame 23, a corresponding disconnection of the supply lines occurs. For this purpose, the coupling device can have appropriate plug- in connections. If it is possible to disconnect a coolant supply by means of the coupling device, such a supply line plug- in connection is constructed such that it is sealed appropriately.
