Definitions
- the present invention relates to a device for light control, in particular a device for light control with at least one light sensor which provides an actual value for the brightness at its output, at least one controller, in addition to this actual value, a target value for the brightness can be supplied, a number n of Output terminals, where n is greater than or equal to two, each Nathananschi uss is coupled to the output of a regulator for changing the Lichtstro s of at least one light source, the controller is designed to determine a difference between the setpoint and actual value and Check whether this difference is within or outside a predefinable tolerance band and, if the difference is outside the tolerance band, change the light flux of the lamps that can be connected to the n output terminals accordingly.
- FIG. 1 shows such a device with a light sensor 10, which provides an actual value to a controller 12. This is further supplied from a default device 14, for example, a memory with a user interface, a setpoint.
- the output of the controller 12 is connected to a plurality of electronic ballasts 16a to 16d, wherein each electronic ballast 16a to 16d activates a light source with a luminous flux set by the controller 12.
- the regulation takes place according to the diagram shown in FIG. 2, in which the difference between the nominal value and the actual value is plotted against the relative luminous flux. You can see a setpoint line around which a tolerance band is applied.
- the controller 12 changes the signal provided at its output such that the light source connected thereto or the light source connected thereto are regulated, ie, the luminous flux supplied to the light sources is increased.
- the output from the controller 12 new dimming default value is therefore implemented by all connected electronic ballasts 16a to 16d uniformly in a new dimming position. This process is repeated until the control deviation is corrected.
- a disadvantage of this known device is that there is often no space for accommodating the controller 12. Also, the central controller 12 requires an additional ehe wiring. The use of a central controller 12 therefore entails undesirable costs.
- the present invention is therefore the object of developing an aforementioned device for light control such that even when using multiple controller the most uniform illumination of a room to be illuminated can be achieved.
- the present invention is based on the finding that the above object can be achieved if the limits of the tolerance band, beyond which a control process is triggered, are made dependent on the current value of the luminous flux.
- This solution results in the dimming positions of the individual electronic ballasts being equalized, since extreme values are the first to be included in the control in case of deviations.
- Dimming position according to the invention is to be understood to mean the supply of a specific luminous flux to the corresponding luminous means. When supplied from a source other than the electronic ballast, this may also mean a signal which controls the other source accordingly.
- the regulator associated with the lowest relative luminous flux begins to be the first device to be excited. Deviations in the dimming positions of the individual devices are thus automatically reduced, virtually self-correcting.
- each ECG a controller is assigned as a separate controller.
- the invention can also be used in devices for light control, each controller being assigned its own sensor.
- a maximum deviation of the dimming levels of the individual lamps from one another could be kept below 10%.
- the control in each controller starts individually, ie independently of the others, if the difference between actual and setpoint is outside the tolerance band, the control ends only when the setpoint is reached and not when the tolerance band limit is reached. This is also to be understood that in the course of a control, the setpoint is exceeded or fallen below, the sign change is detected in the controller and this is used to terminate the control process. This ensures that the same target value is set independently of the direction of control.
- an output terminal is understood to mean the output of a regulator which can be embodied in such a way that one or more light sources can be connected to it, in which case all connected light sources are driven with the same luminous flux.
- the upper or lower limit of the tolerance band or both may depend on the current value of the luminous flux.
- a setpoint line is arranged within the tolerance band, the setpoint line coming closer to the upper limit of the tolerance band, the lower the value of the luminous flux.
- the setpoint line preferably touches the upper limit of the tolerance band in the minimum value of the luminous flux.
- the nominal value line gets closer to the lower limit of the tolerance band, the greater the value of the luminous flux.
- the setpoint value line touches the lower limit of the tolerance band in the maximum value of the luminous flux.
- a further preferred embodiment is characterized in that each controller is associated with a memory in which a characteristic curve and / or a characteristic field is stored, which is associated with a lighting means, in particular for determining the control behavior.
- the control behavior comprises, as a parameter, in particular a predefinable value of the luminous flux as a function of the determined difference between the desired value and the actual value and / or the control speed. For example, it can also be taken into account in this context that due to an exponential dimming curve, a change by one DALI dimming step at high luminous flux, in absolute terms, causes a greater change in the light than at low luminous flux.
- Figure l is a known from the prior art device for light control;
- FIG. 2 shows the tolerance band used in the control in the prior art;
- Figure 3 shows an embodiment of a device according to the invention for light control
- FIG. 4 shows the tolerance band used in a control device according to the invention.
- FIG. 3 shows an embodiment of a device according to the invention for light control. It comprises a sensor 10 which provides an actual value to four electronic ballasts (ECGs) 20a to 20d. Within the ECGs, this actual value is supplied, in addition to a desired value provided by a device 14, to the regulators 22a to 22d arranged in the respective electronic ballast. Within the controller, the difference between the setpoint and the actual value is determined and it is determined whether this is within or outside the tolerance band, see FIG. 4. The permissible deviation depends strongly on the current relative luminous flux. The setpoint line comes closer to the upper limit of the tolerance band the lower the value of the luminous flux is. Conversely, the setpoint line approaches the upper limit of the tolerance band the closer the value of the luminous flux is.
- ECGs electronic ballasts
- each controller 22a to 22d has a memory (not shown), in which a characteristic curve and / or a characteristic field of the respective controller 22a to 22d associated with the lamps 18a to 18d is stored.
- the lighting means 18a to 18d may be different, for example a mixture of LEDs and fluorescent tubes.
- the tolerance band shown in FIG. 4 ensures that devices which have already been regulated, for example, will be regulated further later than devices which still have the greatest control potential. The same applies to Abregein.
