Definitions

  • Embodiments of the present invention refer to a method and a corresponding apparatus for defining illumination parameters, like a color or an illumination angle.
  • Preferred embodiments refer to a computer program, like an APP which can be carried out by use of a computer, like a smart device (smart phone or tablet PC), for controlling one or more illumination devices via illumination parameter.
  • Conventional illumination control is performed by use of light mixing desks, which often make use of the DMX standard. Additionally, there are computer implemented variants, like the software DMX control. Both form an effect generator for controlling lighting fixture effects to be reproduced by use of one or more illumination devices. These generators are handled by selecting a preprogrammed effect engine where it is possible to treat different parameters and in this way makes it possible to change the effect generator behavior. Conventional effect generators have the drawback that they are quite complex so that the operator convenience is limited. Therefore, there is a need for an improved approach.
  • An objective of the present invention is to provide a control approach for the illumination device having an improved tradeoff of flexibility and operator convenience.
  • Embodiments of the present invention provide a method for defining illumination parameters.
  • the illumination parameters can be defined to certain colors and/or to room directions/illumination angles and/or to other parameters defining illumination effects.
  • the method comprises the steps:
  • Embodiments of the present invention are based on the principle that by use of a graphically illustrated illumination space, like a color space or a position space, a user can easily define two or more points within the illumination space which are assigned to illumination parameters, such that the parameters can be stored. For example, the user defines two points assigned to two different colors, so that when outputting the stored illumination parameters the illumination device can reproduce the two colors subsequent to each other. Consequently, embodiments of the present invention let users have a more intuitive way to handle lighting effects by drawing and/or taping a lighting effect.
  • the two or more points assigned to the respective illumination parameter are also assigned to points of time or relative points of time. Therefore, the method comprises a step of defining a first and a second point of time for the first and the second light effects or wherein the method comprises the step of defining relative points of time for the first and the second light effects.
  • the method may comprise the step of defining a transition duration which is variable or predetermined, wherein the transition duration defines relative first and second points of time for the first and the second light effects.
  • a speed controller may be used for defining the transition duration. The speed controller determines a duration, e.g., five seconds, thirty seconds or one minute during which the first effect is replaced by the second effect.
  • the method may comprise the step of outputting control commands is performed, such that the first illumination effect according to the first illumination parameter is performed at a first point of time and the second illumination effect according the second illumination parameter is performed at a second point of time.
  • the method comprises the step of defining a third point of the illumination space, wherein the third point is assigned to a third illumination parameter.
  • This third point may lie on a line, straight line or bent line, together with the first and the second point within the illumination space or may be somewhere else in the illumination space, so that a zigzag line is generated.
  • further points between the first and the second point may be defined, e.g. to generate a straight, curved or zigzag line.
  • All points on the line can be assigned to further illumination parameters, so when controlling an illumination device according to the further illumination parameters a transition between the first and second effect (according to the first and second illumination parameter) is defined.
  • the step of outputting the control commands may be performed, such that the illumination device reproduces the third illumination effect according to the third illumination parameter or the further illumination effect(s) according to the further illumination parameters.
  • a preferred embodiment starts from the assumption that the illumination space is (graphically) provided on the display, e.g., a display of a smart phone or tablet PC.
  • the first and second illumination points are defined by tipping on the touch screen, i.e. manually / as response on a user input. For example, just the certain points within the illumination space may be selected or the user can define the points by drawing a respective line within the illumination space so that a plurality of points (subsequent to each other) are defined.
  • the method may further comprise the step of defining a transition between the defined points, e.g., the first and the second point of the illumination space by connecting the points, wherein the connection comprises a plurality of further points.
  • this definition of the further points may be performed automatically.
  • the connection may be a straight connection or a bent connection.
  • the definition of a transition has the benefit in that an illumination scene having a plurality of clearly defined transition points are available. This enables for the subsequent step of outputting control commands that illumination effects, according to the parameters belonging to the plurality of connection points, can be output so that a smooth transition between the first and the second or the first, the second and the third illumination effect is enabled.
  • the illumination effects are generated in the order as given by the (input) order of the points / parameters
  • the illumination space comprises a color space, wherein the first illumination parameter is assigned to a first color and the second illumination parameter is assigned to a second color.
  • the illumination space may be a position space.
  • the first illumination parameter defines a first illumination direction or first illumination angle, like plus 45 degree of the tilt and wherein the second illumination parameter defines a second illumination direction or a second illumination angle, e.g., minus 45 degree.
  • the illumination space may comprise one dimension, e.g., the tilt angle, or more than one direction, e.g., two directions, for example the tilt angle and a deviation angle (left right).
  • Controlling by use of one dimension is typically used for illumination devices having just one movable axis, like in illumination bar, wherein the two-dimensional control approach may be used for illumination devices which can be directed within the room to at least two directions.
  • parameters belonging to one dimension may be used for controlling a zoom.
  • the color space and the position space may be combined, so that one dimension refers to an angle, while the other direction refers to an illumination color or a brightness.
  • the above discussed approach for controlling is flexible for defining a plurality of illumination parameters belonging to different properties of an illumination scene.
  • the transition duration may be defined together with the points. Since all illumination points or the assigned parameters are stored, the effect may be repeated for another or a plurality of another circuit. In other words, this means that the first and second points of the illumination space are defined based on a user command.
  • Another embodiment refers to a software for performing the method since a plurality of steps are computer implemented.
  • an apparatus or mobile device like a smart phone or table PC, which comprises a user interface, a memory and a control interface.
  • the user interface is configured to provide an illumination space, wherein the user interface is configured to receive a user command defining a first point of the illumination space and a second point of the illumination space.
  • the user interface may be a touch screen.
  • the memory stores the first and second illumination parameter belonging to the first and second points of the illumination space.
  • the control interface is configured to output control commands to an illumination device so as to induce the illumination device to reproduce the first light effect according to the first illumination parameter and a second light effect according to the second illumination parameter.
  • this apparatus/mobile device may be enhanced by features which have been discussed above.

  • the illumination device is configured to reproduce illumination effects according to the illumination parameter 1c and 2c (i.e. reproducing illumination effect 1c before reproducing illumination effect 1c).
  • the illumination device may be an illumination device comprising RDB LEDs so different colors can be reproduced.
  • the illumination parameters 1c and 2c are standardized so that the illumination device can directly reproduce the respective color.
  • other illumination devices like turnable spots or pivotable ligning bars may be used which are configured to be controlled by illumination parameters (cf. 1c and 2c), e.g., defining a pivoting angle or an illumination direction.

  • the point 14c is not necessarily arranged on the connection line of the points 14a and 14b.
  • a step 120c, which is illustrated subsequent to the step 120b may also be performed between the step 120a and 120b so that a position between 14a and 14b should be defined.
