Technical Field
The present invention relates to a method for controlling a lighting system for producing a light effect using a lighting console.
Background
Lighting consoles are used to control lighting systems, such as those used on theaters and concert stages. Typically, the lighting system comprises a plurality of lighting devices, such as stage spotlights, wherein the lighting devices independently in many cases can be switched between a plurality of lighting states, such as between different colors. These different illumination states of the lighting device are controlled in the illumination program of the lighting console by means of programmed adjustment parameters. When the lighting program is running, the adjustment parameters are then transmitted as adjustment commands, for example as DMX commands, to the lighting devices via the respective data links. A common lighting system may include up to thousands of lighting devices.
The so-called light effect is particularly important for the creation of stage performances. These light effects are program parts of the lighting program that continuously run a certain combination of adjustment values of the adjustment parameters to be set. By generating such light effects, for example, a particular spotlight can be controlled to have the following effects: this effect performs a predetermined motion curve, for example a circular motion, on the stage with the stage light cone. In each case, the light effect is generated based on the fact that: a specific combination of adjustment values is generated and sent to the lighting device in order to achieve the desired effect in this way.
The disadvantages of the known method for controlling a lighting system for producing a light effect by means of a lighting console are: the combination of adjustment values required for programming this is very complex and therefore requires an increased expenditure of time. Thus, programming complex light effects is not possible in many stage shows because programming is too time consuming for the light show creator.
Disclosure of Invention
In view of this prior art, it is therefore an object of the present invention to propose a new method for controlling a lighting system by means of a lighting console, which method allows light effects to be produced very easily and very quickly.
Said object is achieved by a method according to an embodiment of the present invention.
An advantageous embodiment of the invention is a method of an alternative embodiment of the invention.
The method according to the invention is based on the following basic idea: at least two adjustment parameters intended for creating the light effect form an adjustment range plane. The limitation of the adjustment range plane is defined by the physical limitation of the settable adjustment range of the lighting device, for example by the maximum adjustment angle of the adjustable lamp or by the maximum brightness of the spotlight. In order to control the light effect, it is now necessary to select a point from an adjustment range plane, each point in the adjustment range plane defining a combination of adjustment values that can be sent as an adjustment command to the lighting device.
In order to produce a light effect, it is now envisaged according to the invention that at least two intersection points are initially established in the adjustment range plane. Each of these intersection points is defined by a pair of two adjustment values forming an adjustment range plane.
Subsequently, by means of a predetermined algorithm, an effect function curve linking all intersection points in the adjustment range plane is calculated. The effect function curve covers all points in the adjustment range plane, which points can then be combined as adjustment values for producing the light effect.
Subsequently, a combination of adjustment values lying on the curve of the effect function is then selected.
In a final step, the adjustment value combinations selected from the effect function curves are then sent from the lighting console to the lighting devices to perform the light effects on the stage. The adjustment value combination may be sent as a DMX command.
Which adjustment parameters are selected to produce the light effect is basically arbitrary and depends on the type of light effect desired. For example, possible adjustment parameters such as brightness and/or color (color channel) and/or scaling factor as a plane for forming the adjustment range when executing the method according to the invention are eligible.
The specific sequence of movements of the lighting devices mounted to be adjustable is crucial for creating the light effect. It is particularly important that the lighting device is arranged pivotable about two pivot axes. The two angles of adjustment of the lighting device pivotable about two pivots are commonly referred to as level and pitch. In order to be able to define a specific sequence of movements of these lighting means in the light effect, it is therefore particularly advantageous if the two adjustment angles (horizontal and pitch) of the pivotable lighting means define two adjustment value axes in the adjustment range plane.
In order to allow a smooth transition when controlling the light effect, it is advantageous if the effect function curve is calculated as a continuous function without any discontinuities in the function map.
Which algorithm is used to calculate the effect function curve after establishing the intersection point in the adjustment range plane is basically arbitrary. This calculation can be realized particularly easily and accurately if the effect function curve is calculated as a spline function of the nth order. In particular, the second-or third-order spline function can be calculated very quickly and therefore almost in real time to link the intersection points that have been established before in the adjustment range plane by means of the continuous effect function curve.
Furthermore, it is particularly advantageous if the effect function curve exhibits a closed-loop function diagram. When the method according to the invention is operated, the closed loop function curve can thus be operated a number of times in succession when controlling the light effect, to achieve a corresponding repetition of the light effect.
In order to give the creator of the light effect another creative aspect, it is particularly advantageous if the inclination of the effect function curve in the intersection point is predetermined as a boundary condition for calculating the effect function curve. In other words, this means that not only the intersection point itself but also the inclination in the intersection point is predetermined as a boundary condition when calculating the effect function curve.
In which way the creator of the light effect predetermines the inclination of the effect function curve is essentially arbitrary. This can be achieved particularly easily, since the creator predetermines the tangent in the intersection point. The course of the tangent then produces the inclination of the effect function curve in the intersection point.
In its basic form, the method according to the invention is used for controlling a lighting system when realizing a light effect by means of a lighting device. However, if a plurality of lighting devices are involved at the same time, the light effect has a particularly rich effect. According to a preferred method variant, it is therefore envisaged that, in order to create a light effect, a plurality of lighting devices are actuated simultaneously, a separate effect function curve being calculated for each lighting device. The effect function curves of the individual lighting devices may in any case also be identical or at least similar.
In which way the adjustment range plane is displayed for the creator of the light effect is basically arbitrary. It is preferable to display the adjustment range plane on a screen of the lighting console.
Furthermore, the way in which the creator of the light effect establishes the intersection point in the adjustment range plane is basically arbitrary. This can be achieved particularly easily, since the screen of the lighting console presents a touch-sensitive surface. The creator of the light effect may then establish the intersection point in the adjustment range plane by touching the touch sensitive surface of the screen. When performing a light effect, it is necessary to select the respective combination of adjustment values corresponding to the program sequence on the effect function curve.
The manner in which the selection is made is essentially arbitrary. According to a preferred embodiment, it is envisaged that the adjustment value combinations selected in each case from the effect function curve have equal distances on the effect function curve. The equal distances between the various combinations of adjustment values correspond to the following specific operating frequencies: the lighting device will be actuated at this specific operating frequency when performing the light effect.
The method according to the invention allows efficient creation and execution of light effects, in particular when calculating the effect function curve of a spline function. Since this calculation can be performed by means of special hardware elements, the processing time is very short and therefore almost real-time, and the calculation of a continuous effect function curve and the selection of adjustment value combinations from the effect function curve can be almost real-time. Thus, in other words, this means that the light effects do not have to be calculated and the corresponding adjustment value combinations do not have to be stored in the table before the lighting program is executed. In contrast, in the actual sequence of the program, the individual combinations of adjustment values are calculated in each case in real time, which considerably increases the effectiveness.
