Description

Vorrichtung zur Erzeugung von Lichteffekten mittels Laser Device for generating light effects using a laser
Beschreibungdescription
Die Erfindung betrifft eine Vorrichtung zur Erzeugung von Lichteffekten mittels Laserstrahl für den gewerblichen Bereich, z.B. Werbung, und als kostengünstige Alternative zur Verwendung von konventionellen Leuchtmitteln für Räume des Wohnbereiches und als Effektgerät.The invention relates to a device for generating light effects by means of a laser beam for commercial use, e.g. Advertising, and as an inexpensive alternative to the use of conventional illuminants for rooms in the living area and as an effect device.
Bisher bekannt (z.B. EP 0 202 632 ) sind vorallem sogenannte Bühnenlaser zur Erzeugung von Lichteffekten. Zur Sicherheit der Betreiber und vorallem der Zuschauer und Gäste sind dabei entsprechende Vorschriften einzuhalten, die in der Regel Spezialinstallationen und -ausrüstungen, die in der Regel sehr teuer sind, verlangen.So far known (e.g. EP 0 202 632) are so-called stage lasers for generating light effects. For the safety of the operator and, above all, the spectators and guests, appropriate regulations must be observed, which usually require special installations and equipment, which are usually very expensive.
Die Laserbaugrupppe ist bei diesen Anlagen fest an der Wand gehaltert. Besonderer Sorgfalt fällt der Strahlüberwachung , der Laserstrahlführung und den Sicherungseinrichtungen (Not- Aus-Schalter ) zu , die bisher nur von stationären Einrichtungen realisierbar waren . Die Wirksamkeit von Bülmenlaseranlagen ist wegen der bisher aus sicherheitstechnischen Gründen festgelegten , an einen bestimmten Standort gebundenen Unbeweglichkeit der Anlage sehr begrenzt . Ein weiterer Nachteil stationärer Laser ist ihr oftmals unvermeidbarer Transport zur Wartung und Justage in dafür ausgerüstete Werkstätten , der mit Demontage und Wiederaufbau verbunden ist und eine abermalige Gefahrdung der Anlage darstellt , abgesehen von der Gefährdung des Wartungspersonals.In these systems, the laser assembly is firmly attached to the wall. Special care has to be taken with the beam monitoring, the laser beam guidance and the safety devices (emergency stop switch), which were previously only possible with stationary devices. The effectiveness of Bülmenlaseranlagen is very limited due to the immobility of the system, which was previously determined for safety reasons and is tied to a specific location. Another disadvantage of stationary lasers is their often unavoidable transport for maintenance and adjustment in workshops equipped for this purpose, which is associated with disassembly and reconstruction and represents a further risk to the system, apart from the danger to the maintenance personnel.
In der DD 286 296 wird dazu ein Verfahren und eine Einrichtung zum Betreiben einer ortsveränderlichen Laseranlage zur Erzeugung von Lichteffekten beschrieben , bei der der Laser , alle Versorgungs- und Positionierbaugruppen auf einem ortsveränderlichen, verfahrbarem Träger angeordnet sind. Der ortsveränderliche Träger ist jedoch mit mindestens zwei in einer festen Richtung definiert verfahrbaren starren Verriegelungsanschlüssen und Verriegelungsaufnahmen zur Lagefixierung der Einrichtung versehen. Der Verriegelungsanschluss weist eine derartige Form auf, daß er unverwechselbar die ortsveränderliche Laseranlage in einer bestimmten Lage ausrichtet und formschlüssig zu einer dieser Lage bestimmenden, an einem definierten Standort befindlichen, Anschlußaufnahme paßfähig ist und daß der Verriegelungsanschluß und die entsprechende Anschlußaufnahme die paßfähigen elektrischen Verbindungselemente enthält. Diese Vorrichtung ist aufwendig und erfordert trotzdem ein Sicherheitssystem, das den Laser bei Annäherung, bzw. bei Realisierung von Bedienungs- undDD 286 296 describes a method and a device for operating a portable laser system for producing light effects, in which the laser, all supply and positioning assemblies are arranged on a portable, movable carrier. However, the portable carrier is provided with at least two rigid locking connections and locking receptacles which can be moved in a fixed direction in a defined direction in order to fix the position of the device. The locking connection has a shape such that it unmistakably aligns the portable laser system in a specific position and is form-fit to a connection receptacle which determines this position and is located at a defined location, and that the locking connection and the corresponding connection receptacle contains the fitable electrical connecting elements. This device is complex and still requires a security system that the laser when approaching, or when implementing operating and

Eine Abdeckhaube dient lediglich als Staubschutz . wobei die Laserstrahlung weiterhin durch offene Auskoppelfenster in der Abdeckhaube hindurchgeführt werden und in den freien Raum fallen .Maintenance work switches off. A proximity switch is particularly required for implementation. Hazards are still not completely excluded. A cover hood only serves as dust protection. the laser radiation continue to be passed through open decoupling windows in the cover and fall into free space.
Herkömmliche Laserlichtanlagen (z.B. EP 0 202 632) sind außerdem durch höhere Laserleistung und ihr offenes System sehr teuer und energiewirtschaftlich ungünstig .Conventional laser lighting systems (e.g. EP 0 202 632) are also very expensive due to their higher laser power and their open system and are unfavorable in terms of energy.
In der Patentanmeldung DE 199 30 821.7 wird eine Vorrichtung zur Erzeugung von Lichteffekten mittels Laserstrahl, insbesondere für Show- und Bühneneffekte, aber auch als kostengünstige Alternative für konventionelle Leuchtmittel für Räume des Wohnbereiches, mit einem Laser und einer Ablenkeinheit für den Laserstrahl dargestellt, die von einem Gehäuse umgeben und ortsveränderlich ist. Ein Teil der Gehäuseinnenseite weist eine Reflexionsebene aus, die verspiegelt und mit einer unregelmäßigen Oberfläche ausgestattet ist, und ein weiterer Teil der Gehäusefläche ist als transparente rauhe Projektionsebene zurPatent application DE 199 30 821.7 describes a device for generating light effects using a laser beam, in particular for show and stage effects, but also as an inexpensive alternative for conventional ones Illuminant for rooms in the living area, shown with a laser and a deflection unit for the laser beam, which is surrounded by a housing and can be moved.

In der DE 40 03 923 ist ein Lichtstreukörper beschrieben, der aus transparentem Kunststoff besteht und durch eine kurzzeitige Wärmebehandlung eine ober- flächenverändernde Reaktion in Form von Luftbläschen zur Folge hat, durch die die unterschiedliche Lichtbrechung verursacht wird.DE 40 03 923 describes a light scattering body which consists of transparent plastic and, by brief heat treatment, results in a surface-changing reaction in the form of air bubbles, which causes the different light refraction.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Erzeugung vonThe invention has for its object a device for generating
Lichteffekten mittels Laserstrahlen zu schaffen , die bei vorteilhafter Geometrie keine Reflexionsflächen erforderlich macht, die Laserstrahlen weitgehend absorbiert und keine Ablenkeinheit für den Laser erfordert.To create light effects by means of laser beams, which with advantageous geometry does not require any reflection surfaces, which largely absorbs laser beams and does not require a deflection unit for the laser.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Laser fest, jedoch einstell- und justierbar, im Gehäuse angeordnet und auf eine der Gehäuseflächen, die als transparente Projektionsfläche ausgebildet ist, gerichtet ist.This object is achieved in that the laser is fixed, but adjustable and adjustable, arranged in the housing and directed at one of the housing surfaces, which is designed as a transparent projection surface.
Zur Erzeugung eines sich ständig ändernden Bildmusters wird der Laserstrahl durch eine sich drehende Scheibe geleitet, die aus einem Profilglas besteht. Auf der Strahleintrittsfläche ist das Profilglas eben und auf der Strahlaustrittsfläche profiliert ausgeführt. Die Scheibe befindet sich auf der Achse eines Getriebemotors, die vorzugsweise eine sehr langsame kontinuierliche Drehbewegung ausführt. Die Projektionsfläche ist Teil des Gehäuses und besteht aus einer matten transparenten Scheibe, vorzugsweise aus Plexiglas. Das Plexiglas ist dazu einseitig geschliffen oder geätzt. Das Gehäuse ist in Form eines Tetraeders oder aber als Pyramide. Kugel oder Kegel ausgeführt, da sie jeweils eine hohe Standfestigkeit besitzen, aber vorallem einen günstigen Betrachtungswinkel ermöglichen. Weitere Bauformen und Kombinationen dieser Geometrien sind selbstverständlich möglich. Außerdem ist es möglich, die Projektion auf beliebige Teile der Mantelfläche des Gerätes auszuweiten.To generate a constantly changing image pattern, the laser beam is guided through a rotating disc, which consists of a profiled glass. The profiled glass is flat on the beam entry surface and profiled on the beam exit surface. The disc is located on the axis of a geared motor, which preferably executes a very slow, continuous rotary movement. The projection surface is part of the housing and consists of a matt, transparent pane, preferably made of plexiglass. The plexiglass is ground on one side or etched.

Schnittdarstellung;Section;
Der Lasermodul 5 (Fig. 2) ist mittels einer Halterung 9 fest auf der Grundplatte 8 angeordnet und auf eine im Gehäuse 1 integrierte Projektionsfläche 2 gerichtet. Das Gehäuse 1 hat im Ausführungsbeispiel die Form eines Tetraeders (Fig. 1 ) und weist zugleich den Vorteil eines günstigen Betrachtungswinkels auf. Die Projektionsfläche im Gehäuse 1 besteht aus einer aufgerauhten Scheibe, z.B. aus einer aufgerauhten Plexiglasscheibe. Zur Abbildung eines Interferenzmusters ist vor den Lasermodul 1 in dessen Lichtstrahl eine sich drehende Formglasscheibe 3, z.B. aus Schlierenglas, angeordnet, so daß der auf die sich drehende Scheibe auftreffende gebündelte Laserstrahl zerstreut aus der Formglasscheibe 3 austritt und als Interferenzmuster auf der Projektionsfläche 2 abgebildet wird. DieThe laser module 5 (FIG. 2) is fixedly arranged on the base plate 8 by means of a holder 9 and directed onto a projection surface 2 integrated in the housing 1. In the exemplary embodiment, the housing 1 has the shape of a tetrahedron (FIG. 1) and at the same time has the advantage of a favorable viewing angle. The projection surface in the housing 1 consists of a roughened pane, e.g. from a roughened plexiglass pane. To image an interference pattern, a rotating molded glass pane 3, e.g. made of Schlieren glass, arranged so that the focused laser beam striking the rotating disk emerges from the molded glass sheet 3 and is imaged on the projection surface 2 as an interference pattern. The
Formglasscheibe 3 befindet sich dazu auf einer Achse eines Getriebemotors 4, der die Formglasscheibe 3 mit ihrer unregelmäßigen äußeren Oberfläche in eine Drehbewegung versetzt. Der den Laserstrahl erzeugende Lasermodul 5 bedarf so keiner Ablenkung. Das Profilglas ist auf seiner Lichteintrittsfläche eben und nur auf der Lichtaustrittsfläche unregelmäßig profiliert ausgeführt.For this purpose, shaped glass pane 3 is located on an axis of a geared motor 4, which sets the shaped glass pane 3 with its irregular outer surface in a rotational movement. The laser module 5 generating the laser beam thus does not require any deflection. The profile glass is flat on its light entry surface and only irregularly profiled on the light exit surface.
Auf der Halterung 9 kann weiterhin eine erforderlich werdende Leiterplatte 6 angeordnet werden. A circuit board 6 that becomes necessary can also be arranged on the holder 9.
