Definitions
- the invention relates to a method for the relative control of a lamp, a controller for the relative control of a lamp and a lighting system.
- lighting systems of modern design allow to transmit control commands for controlling lights to the lights or their operating devices.
- lighting control gear may be configured to receive and implement control commands generated by the DALI ("Digital Addressable Lighting Interface") standard.
- DALI Digital Addressable Lighting Interface
- Such systems also allow control of complex control operations of a multiple light lighting system
- the intensity and / or the hue and / or the color temperature of one or more luminaires can be controlled Basically, a control can take place in two different ways: In the case of an "absolute" control or "absolute” setting, this is an absolute one
- the control value to be set at the end of the process is already fixed when the process is initiated and a control command is issued to the luminaire
- An example scenario is the selection of one of several predefined moods of a lighting system, which are assigned to a luminaire ete intensity and color temperature are fixed and a
- the absolute control value which the luminaire is to occupy at the end of the process is not yet fixed at the beginning of the process. Rather, a current control value of a manipulated variable of the lamp should be increased or decreased by one or more increments, as long as, for example, a button is pressed.
- An exemplary scenario is the adjustment of intensity during dimming, which can be done, for example, in response to the actuation of a button.
- a conventional implementation for controlling lights in "relative” driving or “relative” setting is that the same control command is repeated as long as the process continues. In this way, for example, by always re-output the same "UP” or “DOWN” command according to the DALI standard, an incremental increase or decrease of a control value of a luminaire can be achieved. However, this procedure can lead to a relatively high utilization of a bus system. This can make it difficult to handle other commands in a timely manner.
- WO 99/60804 A1 describes information systems in which a light control can take place via a network.
- a light intensity can be increased or decreased, in each case in response to a single operation of a switch, a corresponding command is generated. If the switch is operated several times, several commands are generated accordingly.
- a dimming rate can be variably programmed over the network.
- the object of the invention is to provide a method, a controller and a lighting system that allow efficient relative control.
- the invention is in particular the object of specifying a method for the relative control of a luminaire, a controller for the relative control of a luminaire and a lighting system in which not always in very short distances the same command must be generated in order to achieve a relative control.
- a method for the relative control of a luminaire is specified.
- An actuation of an actuating element is detected.
- the following steps are cyclically performed: determining a target control value corresponding to one of a plurality of nodes that are approached sequentially during actuation; Generating a setting command in dependence on the target setting value; and outputting the control command to the target control value Approach corresponding interpolation point with a predetermined cross-fade time.
- a predetermined period of time is waited before a further setting command is issued in order to approach a further supporting point which corresponds to a further target setting value.
- positioning commands are cyclically generated and output while an actuating element is actuated, wherein successive positioning commands are output only at intervals corresponding to the predetermined period of time.
- the manipulated variable that is set with the method can include an intensity.
- the different target setting values which are determined one after the other can correspond to different brightness values or intensities of the luminaire.
- the manipulated variable set by the method may include a color temperature or a hue. In this case, the different target setting values which are determined one after the other may correspond to different color temperatures or color tones of the luminaire.
- the actuator may be a button.
- the button can be integrated into a control panel, which can be designed, for example, as a touch-sensitive control panel.
- the target control values can each be determined as a function of whether the key is actuated in such a way that an increase in a manipulated variable is to be achieved or whether the key is actuated in such a way that a reduction in the manipulated variable is to be achieved.
- the target control value can be determined in each case depending on the predetermined fade time.
- the target control value can be determined in each case depending on an initial control value, which the control variable has at the beginning of the actuation of the actuating element.
- a stop command may be generated and output to terminate a crossfade operation.
- the stop command does not have to contain a new target control value.
- the stop command can cause an unwanted continuation of a crossfade operation to that in the last control command are suppressed when the end of the actuation of the actuator is detected.
- a final control value can be determined.
- a correction control command can be generated and output depending on the final control value.
- the final control value can be calculated by a controller and determined by a duration of actuation of the actuating element. This allows a small correction of the manipulated value after the stop command has been issued. In this way, for example, delays in the execution of setting commands and / or the stop command that can occur in the operating device of a lamp can be compensated.
- the stop command may be issued before the predetermined period of time has elapsed after the output of the control command last generated before the end of actuation of the actuator. Thus, it is not necessary to wait for the stop command to be issued until the predetermined time has expired again.
- the stop command may be generated and output immediately after the actuation of the actuator ends.
- the predetermined period of time, after each of which a new control command is output, may be equal to the predetermined fade time or less than the predetermined fade time.
- a new control command can be generated periodically at the end of the predefined transition time or before the predefined transition time has elapsed.
- a new control command can be generated and output with a new target control value just when the manipulated variable of the light reaches a target control value contained in the most recently issued control command.
- a new control command can be generated and output with a new target control value shortly before the time at which the manipulated variable of the luminaire reaches a target control value contained in the last-issued control command.
- An input signal indicative of a state of the actuator may be evaluated at a rate greater than the inverse of the predetermined period of time.
- the state of the actuating element can thus be interrogated at time intervals which are small compared to the predetermined period of time after which a new control command is issued. This can be reacted quickly to a change in the state of the actuating element.
- adjacent support points of the plurality of support points may each have the same control value difference.
- the predetermined cross-fading time may have a fixed value, which is not changed during the continued actuation of the actuating element.
- a first control command can be generated, which comprises the predetermined fade time and a target control value.
- the positioning command can be transmitted to an operating device of the luminaire.
- the operating device can approach the target setting value continuously or in several stages in the predefined fade time.
- the positioning command can be a positioning command according to the DALI standard.
- the positioning command can include a DALI short address of the luminaire.
- the positioning command can be output to a bus, in particular a DALI bus.
- a controller for the relative control of a lamp includes a signal input for receiving an input signal indicative of a state of an actuator.
- the controller includes an interface for issuing commands.
- the controller includes control logic coupled to the signal input and the interface and configured to determine whether the actuator is actuated in response to the input signal.
- the control logic is arranged to determine, during an actuation of the actuator, a target control value corresponding to one of a plurality of nodes to generate a control command in response to the target control value and to output the control command via the interface to a support point corresponding to the target control value to approach a predetermined fade time.
- the control logic is set up so that, during a continued actuation of the actuating element, after the outputting of the setting command before issuing a further setting command for starting a further supporting point, which corresponds to a further target setting value, a predetermined period of time is waited. Further developments of the control and the effects thus achieved correspond to the developments of the method according to embodiments.

- the lighting system 1 may include further lights, each of which is assigned a unique address to allow addressing of control commands by the controller 10.
- the lighting system 1 comprises an operating device 20 for the luminous means 2.
- the operating device 20 may be configured as a ballast.
- the operation of the operating device 20 takes place on the basis of control commands, which the operating device 20 receives from the controller 10.
- the operating device 20 has an interface 23 via which a Data communication with the controller 10 takes place.
- the data communication can be wired, for example via a bus 5, or wirelessly.
- the data communication may be a digital data communication.
- the bus 5 may be a DALI bus and commands may be generated according to the DALI standard. Other operating devices may be connected to the bus 5.
- Commands received by the interface 23 are processed by a controller 21 which controls the operation of the operating device 20 in response to the received command.
- the operating device 20 may be designed such that it permits intensity control and / or color control of the luminaire.

- the DC link circuit generate an intermediate circuit voltage, which is converted by the inverter into a high-frequency AC voltage, which in turn can be supplied to the output side load circuit having output terminals for the light source 2.
- the brightness of the luminaire can then be changed, for example, by changing the frequency of the alternating voltage generated by the inverter.

The operations are repeated cyclically, with no new control command for relative control of the light is issued between successive control commands during a predetermined period of time.
- the target control values determined in each case are only the intermediate values which the control variable of the luminaire is to assume after a predetermined crossfade time, not the final value of the manipulated variable at the end of the relative control. This final value is not yet known as long as the target setting values are cyclically determined and corresponding positioning commands are generated and output.

- the final value and the length of the time interval in which cyclically new positioning commands are generated at a time interval are defined by the time at which the actuating element is released by the user.
- the relative control of the luminaire is based on support points. During the continued actuation of the actuating element, a plurality of interpolation points of the manipulated variable of the luminaire are approached sequentially, which correspond to the various successively determined target manipulated values. The output of a new control command for the relative control of the luminaire is only carried out after a predetermined period of time.

- the target control values determined in step 43 are rather intermediate values which are approached sequentially while the button remains pressed.
- a target control value, which is shown in step 43 is determined, thus corresponds to a support point to be approached in the control of the lamp.
- the target control value that is generated and output in the last cycle before the end of the button actuation is no longer reached by the luminaire.
- the corresponding blending operation is aborted by the stop command issued at step 48.
- FIG. 4 is a schematic diagram for further explaining the operation of controllers and methods of embodiments.
- a controller performs a relative control of a lamp depending on an input signal 51.
- the input signal 51 indicates an actuation of an actuating element, for example a button.
- a first edge 54 of the input signal 51 indicates a start of the actuation of the actuating element, which lasts until a second edge 55 of the input signal 51.
- the manipulated variable of the luminaire has an actual manipulated variable P_i, which is the manipulated variable at the beginning of the process.
- a support point 61 in which the manipulated variable of the luminaire has a first target control value P_1 assigned to the interpolation point 61
- a further interpolation point 62 in which the manipulated variable of the luminaire has a reference point 61
- P_2 associated with the further interpolation point 62
- a control value difference 69 between the first target control value P_1 and the actual control value P_i at the beginning of the process may be equal to a control value difference 69 between the second target control value P_2 and the first target control value P_1.
- a manipulated variable difference between target control values output in successive control commands may be identical. If the manipulated variable of the luminaire can each assume only predetermined, discrete values, the manipulated variable differences 69 can be determined such that they bridge over several of these values.
- the manipulated value differences 69 which determine the respectively determined target setting values for each crossfade. Determine operation, can be determined by the controller depending on the fade time 68.
- changes of the manipulated variable can be made in each case by the same manipulated variable difference and in the same, predetermined transition time.
- the crossfading process in which the manipulated variable is changed continuously or in several stages, can take place under the control of the operating device of the luminaire.
- a first control command 71 is generated at or shortly after detection of the edge 54 of the input signal 51, which indicates the beginning of the actuation of the actuating element.
- the first control command 71 may include the first target control value P_1.
- the first adjustment command 71 may further include the fade time 68.
- the operating device of the luminaire changes the manipulated variable to the first target setting value P_1, wherein a crossfading process with the crossfading time 68 is performed.
- a second adjustment command 72 is generated and output.
- the second adjusting command 72 can thus be generated when the manipulated variable of the luminaire has approached the first interpolation point 61, which corresponds to the first target control value P_1 contained in the preceding first control command 71.
- the second control command 72 may include the second target control value P_2.
- the operating device of the luminaire changes the manipulated variable to the second target manipulated value P_2, wherein a crossfading process with the crossfading time 68 is run.
- a third setting command 73 is generated and output.
- the third adjusting command 73 can thus be generated when the setting variable of the luminaire has approached the second interpolation point 62, which corresponds to the second target manipulated value P_2 contained in the preceding second adjusting command 72.
- the third control command 73 may include a third target control value P_3.
- the operating device starts a new crossfading process to change the manipulated variable from the second target control value P_2 to the third target control value P_3.
- the stop command 74 is output.
- the stop Miss 74 does not have to contain a new target value.
- the crossfade operation to the target manipulated value P_3 that was last detected before the end of the actuation of the actuator is ended.
- the manipulated variable has a final value P_f, as shown at 64.
- the lamp is on, whereby the manipulated variable has the setting value P f.
- the fade time and the predetermined period of time after each a new control command is issued may be the same, as shown schematically in FIG. 4 shown.
- the fade time and the predetermined period of time after each a new control command is issued each can be longer than 1 second.
- the fade time and the predetermined period of time, after each of which a new control command is issued, as long as the actuation of the actuating element continues for example, each be 1.4 seconds. Such a node spacing in the time domain leads to good results with regard to flickering or low traffic on the bus.
- the controller can computationally calculate a final control value of the manipulated variable.
- the final value can be determined, for example, depending on the duration of the time interval in which the actuating element is actuated continuously.
- the final control value can be determined depending on the actual control value of the lamp at the beginning of the operation and depending on the duration of the time interval in which the actuating element is actuated continuously.
- the controller may output, after the stop command 74, a correction control command 75 which contains the final control value or is otherwise generated depending on the final control value.
- the operating device can set the manipulated variable to the final control value, so that a state shown schematically at 65 is reached.
- the luminaire is on, the manipulated variable of the luminaire having the final control value calculated by the control.
- FIG. 4 shows schematically an increase of a manipulated variable in the case of a relative actuation
- a lowering of the manipulated variable in the case of a relative actuation can be realized in a corresponding manner.
- Different push-button operations for increasing or decreasing can be detected by the control, whereby successive target control values detected during actuation of the push-button can be selectively increased or decreased either by a control value difference.
- the manipulated variable which is set during the process can be, for example, the brightness or intensity of the luminaire.
- the target control values or the final control value can be brightness values in this case.
- FIG. 5 is a flowchart of a method 80 according to another embodiment. The method may be performed automatically by the controller 10 to provide relative control of a luminaire. Steps similar to that described with reference to FIG. 3 described method 40 are denoted by the same reference numerals.
- a check of the button operation at 46, with which an end of the operation can be detected only quasi-continuously repeated with a short waiting time at 49.
- the waiting time at 49 is short compared to the predetermined time period corresponding to the waiting time between the issuing of successive setting commands.
- the stop command is issued at 48 in response to the end of actuation of the button.
- a correction control command is issued.
- the correction setting command can be determined as a function of a mathematically determined final control value of the manipulated variable.
- the final control value can be determined, for example, depending on the duration of the time interval in which the actuating element is actuated continuously.
- the final control value can be determined depending on the actual control value of the lamp at the beginning of the operation and depending on the duration of the time interval in which the actuating element is actuated continuously.
- the final control value can be determined as an absolute control value.
- the control gear can set the control value to the final control value.
- the luminaire is on, the manipulated variable of the luminaire having the final control value calculated by the control.
- the correction setting command issued at 81 may cause absolute digits.
- the continuous modulation of commands is replaced by a control of nodes with a fade time.
- Adjacent interpolation points can have mutually equal manipulated variable differences and can each be approached with the same cross-fading time.
- the manipulated variable changes can be both increasing and decreasing.
- the actuating element comprises a button
- the actuating element may also have other configurations.
- the actuating element which causes the relative actuation can comprise a light sensor.
- a change can also be made according to other characteristic curves.
- a characteristic curve which indicates the desired behavior of the luminaire with a relative activation as a function of the duration of the button actuation, can be stored in the control of the illumination system.
- the characteristic curve can have a non-linear course.
- While embodiments have been described in the context of brightness control and dimming, respectively, the methods, apparatus, and systems of embodiments may be used for other operations where relative location is used.
- the methods, devices and systems can be used in particular whenever a control value change is to be made in response to a push-button operation, the final value at the end of the process and the duration of the process initially not yet known.
- Methods, devices and systems according to embodiments can be used for building lighting.
- Methods, devices and systems according to exemplary embodiments can be used in particular for illuminating offices or business premises, without being limited thereto.
- the relative control is not limited to lights as individual units, but generally to lighting systems in which individual lamps are operated by means of a control gear according to the specifications of the relative control. It may also include more comprehensive lighting systems such as barrel lighting.
- the methods, devices and systems according to the Examples generally relate to the control of bus subscribers in a lighting system. This concerns, for example, the control of bus users with actuator and with continuous, discrete value range.
