Description

The invention relates to a device for controlling a plurality of lights according to the preamble of claim 1.

Such a device of the Applicant is known from DE 198 17 073.4 known. In the known device, the addressing takes place of the individual lights via a LON bus. The known device has proven itself in use.

The known device is in accordance with the object of the invention in such a way that it can be used more variably.

The invention solves this problem with the features of Claim 1, in particular with those of the characterizing part, and is Accordingly, characterized in that at least one lamp at least three differently colored lamps, e.g. a red lamp, a blue lamp and a green lamp, each of which three lamps own separate, individually addressable ballast is associated with each of the brightness level of the associated Lamp is adjustable, wherein an input unit is provided at the at least one color value for the luminaire is input, and wherein a Computer unit is provided which the entered color value in Brightness level values of the three lamps converted, the Computer unit for displaying the color value through the luminaires at least the brightness level values individually addressed to the Ballasts sends.

The principle of the invention consists initially in different to produce colored light. For this purpose, lights are provided, the have a variety of different colored partial lamps, For example, a red, a green and a blue partial lamp. When However, bulbs come for example colored fluorescent lamps Any other light sources, such as LEDs, into consideration.

As differently colored lamps also white lamps, So colorless lamps are considered, with a coloring element, for example, a color filter, e.g. a color foil, interact.

The color produced by a lamp is the sum the individual colors together. Depending on the brightness level of the individual Lamps results in a different overall color of the lamp.

The peculiarity is that every single lamp a single addressable ballast is assigned. It can be a separate component for each lamp or alternatively a common component for several different lamps, which is an individual Addressing possibility for the three lamps has.

The device is also associated with an input unit to which a color value can be entered for the luminaire. The entered color value should by the lamp by appropriate calculation of Brightness levels of the individual lamps and by transmission of these Brightness level values are displayed to the ballasts. For this purpose, the computer unit calculates the color value Brightness level values of the three lamps around. The computer unit sends then the brightness level values for representing the color value individually addressed to the ballasts.

The invention initially allows the input defined Color values on the input unit. Furthermore, the Device a particularly simple forwarding of Brightness level values to the ballasts. The inventive Device allows use of the DALI protocol for the Communication between storage unit and the ballasts. The DALI protocol is in Appendix E for ballasts prescribed standard IEC 60929. additional Information can visit the website of the DALI working group at www.dali-ag.org be removed. The content of the retrievable DALI Manual, 2nd edition, is hereby incorporated in the content of this Patent application included.

The DALI protocol is not for driving colored Luminaires provided and designed. Nevertheless, the Device according to the invention the use of the DALI protocol for changing the color of luminaires. In particular, this is in this Context that the computer unit for Representation of the color value the brightness level values directly addressed to the ballasts individually addressed. A resort to the according to DALI protocol actually for the retrieval of light scenes provided light scene memory in the individual ballasts not necessary. The direct, single-addressed transmission The brightness level values, in contrast, allow a very high level Variability.

The computer unit can, for example, two Computing subunits exist, both the storage unit and are assigned to the input unit. In particular, it is advantageous if a computer subunit arranged on the input unit has a part the arithmetic work takes over, for. B. made during inputs and if the memory unit associated with the second Computer subunit transmission of the control information to the individual ballasts, especially if the input unit is disconnected from the device.

A single addressing of the ballasts in the sense of Invention means that the transmission of the Brightness level values each to a specific, individual Ballast and thus to a specific participant of the Network, in particular to a particular colored lamp. The control command used to represent the color value by the Luminaire from the computer unit and / or from the storage unit is sent, thus always contains an Adreßbestandteil.

A device for controlling a plurality of lights is under the name "LUXMATE-Emotion" by the Zumtobel staff GmbH, based in Dornbirn, Austria. In the known Device color values can be entered on a control unit, wherein a conversion of the color values into brightness level values occurs and the brightness level values are individually addressed as light scenes in electronic ballasts are stored. The device uses insofar as provided by the DALI protocol Possibility to save light scenes. To display the color value are sent over the signal line commands that stored Retrieve light scenes. For the representation of the color value by the light Brightness level values are thus not addressed individually directly transmitted. The known device does not allow input of more than two color values and in particular no arbitrary selectable Sequence of color stations. Also a real-time representation, so Color rendering, a color value specified on the input unit is not provided with the known device. Also is due the instruction sets given by the DALI protocol are the number possible storable light scenes, so static color stations on 16 limited.

According to an advantageous embodiment of the invention is the Color value starting from one of the luminaires before entering the Color value associated with output color value within one of the User adjustable time (target time) reached. In a real-time mode the target time can also be chosen almost 0. The input unit thus provides the possibility of a target time by the user to enter the time to change the generated by the lamp Color matches the new value.

The adjustable by the user target time can also be a Circulation time, which is necessary for one pass of a gangway of several Color stations is needed. The target time is in this sense for example, the total circulation time of the color passage. Becomes For example, a target time of 500 seconds for a pass given by ten different color stations, so is the time interval between two color stations - indirectly adjustable by the user - 50 seconds.

According to a further advantageous embodiment of the invention the computer unit and / or the memory unit divides the target time in a variety of time intervals (fading times). The calculator and / or the memory unit calculates between the Output color value and the color value to a corresponding multiplicity Intermediate color values and associated intermediate brightness level values. Then she sends the calculated Intermediate brightness level values and those corresponding to the color value Brightness level values below in the time intervals individually addressed to the ballasts. This embodiment of Invention offers particular advantages in terms of a design of the Color transition. Starting from an initial color value that the Represents light at an initial time, the user can Enter a color value that represents a target value for the luminaire. Of the Target value should be reached within a target time.

If you were to the ballasts only the color value send corresponding brightness level values and you would get one Transition from the initial color value to the color value gradually within the target time, you could under Use of the DALI protocol to the ballasts only the Send target color value and the fading time stored in the ballast use. The problem is, however, that in different Ballasts different dimming curves relative to the emitting luminous flux are stored. This means that within certain, selected fading times, the drive curves for switching the dimming states of the lamps in different Ballasts are different. To be clean, clear and precise To achieve color transitions can, with this embodiment The invention provides a plurality of intermediate values and intermediate stages be calculated and controlled, which within each short Time intervals are controlled. The steps can be on this Be shortened such that it is to achieve a Color transition to the in the individual ballasts stored dimming curve does not arrive anymore. The dimming curve is in no longer resolvable in this sense.

It is particularly advantageous if the time intervals are shorter than 10 Seconds, advantageously less than 5 seconds, and in particular shorter than 2 seconds are selected. Color transitions of such short Time intervals can be the human eye - correspondingly low Color differences required - practically no longer dissolve.

According to a further advantageous embodiment of the invention is the input unit of a separate from the control unit Device provided. This allows for a control unit that is practical only the essential ones required for an end user Can retrieve control commands. The much more complicated, for example, to be operated by a lighting planner input unit, can be a separate unit, for example, part of a Be a computer. The control unit can be very simple in this way be configured and is thus inexpensive to produce. The essential Requirements for storage capacity and performance are of the storage unit provided.

According to a further advantageous embodiment of the invention the input unit is a color value display for (almost) all representable color values, wherein the color value from the Color value display is selectable. The color value display can For example, be a color wheel or a color standard board in the Essentially represents all colors that can be generated by the luminaire. A particular problem in this context is in that the colors displayed on a screen are not necessarily the same Match the color produced by the luminaire in the room. With the The device according to the invention can be the representation of the color value be controlled by the lamp in the installed state.

For this purpose, according to an embodiment of the invention Color value display associated with a cursor, which by means of a Positioning device, e.g. a mouse, along the color value display is controllable by changing the cursor location. The cursor location the computer unit and / or the memory unit assigns a color value to. In this way, there is the possibility of being on the Color value display set color value directly, that is almost in real time, or online, from the luminaire to display to let.

According to a further advantageous embodiment of the invention the color value is calculated from the cursor location in real time and by the lamp shown. In this way, a shift of the Cursors, for example, by moving the mouse to the color to change. A mouse click is not in this embodiment of the invention more required.

According to an alternative embodiment of the invention is to Calculation of the color value from the cursor location the operation of a Actuator required, for example, a left Mouse button. This allows a more defined, safer operation of the Input unit for selecting a color value.

According to a further advantageous embodiment of the invention is at an input unit a plurality of color values (Color stations) can be entered. The multiple color values can be from the Users can be combined in any order. Is possible For example, a color transition, the color stations red-green-red-blue-red-yellow-red-green-red-orange-red-blue-red-violet-red-blue-red-green-red-orange etc. is formed. Advantageously, the input unit asks in a corresponding mode successively the plurality of Color values from the user. The combination of the color values leads to a color transition. This can also be formed endlessly circulating so as to generate corresponding dynamic lighting an infinite loop is programmable.

Preferably, the information (brightness level values) is over the color transition stored in the memory unit retrievable. A Availability is possible through the operating unit. The one-off from a color designer entered color stations at the input unit or color passages can be very comfortable in this way be retrieved.

According to a further advantageous embodiment of the invention sends the memory unit and / or the computer unit for display the color transition the corresponding brightness level values consecutively addressed individually to the ballasts. Such a Transmission may occur during normal operation of the device take place, for example, if a corresponding selection from a Menu item on the HMI device has taken place. Alternatively, the Send process but also during a programming phase of Device be performed at a time so, to which the Input device is connected to the device. This Embodiment allows the input of any number of color stations of a color transition, as in the DALI protocol provided memory locations for light scenes, which are limited to 16, does not need to be resorted to.

According to a further advantageous embodiment of the invention the ballasts communicate with the storage unit and / or with at least a part of the computer unit according to the DALI protocol. This allows compatibility of different ballasts together. In addition, known standards can be used become.

According to a further advantageous embodiment of the invention the signal line is a particular as a USB interface assigned trained interface. By means of this is a computer, especially a laptop, to the device in a simple manner connected. The interface is according to another embodiment of the invention arranged on a housing of the control unit. This allows a particularly easy accessibility.

For this purpose, the interface is in an assembled state of Operating unit, in particular in a wall-mounted state of Operating unit, freely accessible on the housing, especially at the bottom.

The apparatus designated 10 in its entirety in Fig. 1 is merely exemplified in the figures. According to FIG. 1 comprises the device three lights 11a, 11b, 11c, which at an installation in a building, e.g. ceiling side, attached attached. each single luminaire, e.g. the lamp 11a includes, not shown, different colored, individual lamps, for example a red one Lamp, a green lamp and a blue lamp. Each one Lamp of a lamp is each a separate, individually addressable, assigned electronic ballast. Consequently, the Luminaire 11 a, which includes three individual lamps, a group 12 a of three individual, individually addressable ballasts on. It is conceivable that each ballast for each individual lamp own housing has. For example, DALI ballasts come for this The companies Osram, Tridonic or Philips in question, the are commercially available. Alternatively, there is also the possibility that several individually addressable ballasts to a common component are summarized. It is crucial that each individual lamp of the respective lamp 11a, 11b, 11c via the corresponding ballast is individually addressable.

The illustrated three lights are to be understood as an example. The The maximum number of network subscribers is defined by the DALI protocol limited to 64, emitting a colored light Lamp has three lamps and thus three participants. The Network can, of course, in addition to colored lights in addition also have conventional, monochrome lights.

The individual ballasts are on a common Signal line 13 is connected to a memory unit 14. The Memory unit 14 is a controller for the network and can be connected to the Ballasts send commands according to the DALI protocol. The individual ballasts, in Fig. 1 only schematically are meant by the memory unit 14 on the Signal line 13 sent control commands according to the DALI protocol and put the received information in control information for the individual lamps around. In particular, generate the electrical Ballasts different control voltages for each Lamps to different dimming levels and therefore different To achieve brightness level values of the individual. In case that For example, the lamp 11a one red, one green and one blue Fluorescent lamp is assigned, by changing the Brightness levels of individual lamps a change of Total light color, so the color value of this lamp 11a, reached become.

The memory unit 14 is connected via a line 17 with a Operating unit 20 connected. The operating unit 20 communicates with the Memory unit 14 via a different from the DALI protocol Protocol according to the RS485 standard. About the control unit 20 are in the memory unit 14 stored control commands and Information available. In the case that in the memory unit 14 For example, a particular light scene is stored, this can be retrieved from the control unit 20. The light scene can For example, be a static light scene, so that a constant Color is generated. But it can also be a dynamic light scene in be stored in the memory unit 14, for example in shape an endlessly circulating color passage, which has a variety of Color stations leads.

The operating unit 20 is shown schematically in FIG. 2, shown in perspective view. It becomes clear that the Operating unit 20 has a substantially peripheral frame 21st having a display 22, so a screen display, bounded. The display 22 is designed as a touch-screen display, so that by touching the display a circuit for retrieving Control commands of the memory unit 14 can be made.

On the underside 23 of the frame 21 of the control unit 20 is a socket provided. This is a USB interface 19, the connection of a in Fig. 1 denoted by 18 Cable is used. The arranged on the back of the control unit 20, in Fig. 3 schematically indicated fasteners 24 are used the wall-side mounting of the operating unit 20, for example in Area of a flush-mounted socket. In wall mounted state of Control unit 20, the USB interface 19 is readily accessible.

Fig. 1 shows that an input unit 15, in particular a portable computer (laptop) via the cable 18 with the control unit 20 can be connected. The function and operation of the Input unit 15 will be described later. First, be on it It should be noted that also on the memory unit 14, one in FIG. 1 is not shown USB interface 19 for connection to the Input unit 15 may be arranged.

Alternatively come to the use of a USB interface also other interfaces into consideration. A USB interface However, it allows a particularly high level of user comfort.

4 shows an example of a first color value display 25a in the form a color wheel and a second color value display 25b in the form of a Color palette. By means of one shown in the color value display 25b Cursors 26 in the form of a stylized hand with outstretched Index fingers, as they are usually used as cursors in Windows programs Use, can from the color spectrum a color value to be selected. The operation of the device is as follows:

The storage unit 14, the lights 11a, 11b, 11c, the individual electronic ballasts (e.g., groups 12a, 12b, 12c of FIG Ballasts) and the control unit 20 are fixed in a building assembled. Via the USB interface 19, the device 10 with an input unit 15 are connected. The input unit 15 has a color value display for all, at least for essentially all, displayable color values. By way of example, a color wheel 25a is shown in FIG represented, which represents the entire color spectrum.

A cursor not shown in the color chart 25a can now be moved along the color wheel. The on the input unit 15 running or callable software or alternatively a fixed Assign wiring to the current location of the cursor in the Color wheel to a color value too. The color value can, for example, like this shows the fields 27a, 27b and 27c in Fig. 4, also in the form of Scale proportions of a red value, a green value and a Blue value can be displayed. For example, for each of the three 256 scale graduations provided, with the scale value 0 e.g. a switched off state of the red lamp and the Scale value 255 a maximum ON state of the red Lamp corresponds. The intermediate values correspond to the Dimmzuständen. It is crucial that the input unit 15 means a computer unit 16a the current cursor location a color value assigns. The computer unit 16a sends this color value via the Cable 18, the control unit 20 and the cable 17 to the storage unit 14 or to one of the memory unit 14 assigned Computer subunit 16b. The computer subunit 16a and the Computer subunit 16b form in this way a common Computer unit.

The color value received by the computer sub-unit 16b is written by this in brightness level values for the individual partial lamps of the Luminaires converted and directly to the individual Ballasts sent. A representation of a cursor location in the Color value display assigned color value is thus almost in real time by all lights 11a connected to the device 10, 11 b, 11 c possible. In this way, in the context of a lighting design the color selected on the input unit 15 in terms of their Room effect are checked immediately. A representation of the Color value selected on the input unit 15 is convenient in real time, so "online" possible. It has to be considered that the device 10 using the DALI protocol a maximum of 64 Participants can be connected. In the case of colored lights These are a maximum of 21 lights, each with three individual, different colored lamps.

Did you want to address all individually addressed lamps, this is required when using the DALI protocol standing transfer rate has a total response time of 1.6 Seconds. A representation of the color value after its selection in the color value display in real time means in this sense Delay of about 1.6 seconds.

The just described possibility of an online relationship Real-time verification of a set color allows one to the actual architectural conditions adapted lighting and color planning.

The device 10 according to the invention also allows also the setting of a variety of different color stations and their link to a color transition. The number of different Color stations is unlimited. The color stations form one Colorway that revolves endlessly. Also the total circulation time is of the User adjustable, such as the field 28 in FIG. 4 suggests. The number of color stations can be in advance, for example be set in the field 29.

To enter a color transition, for example, after Setting the number of user-requested Color stations from the input device 15 sequentially queried which individual color values are assigned to the color stations should be. For example, a colorway red-green-red-blue-red-orange-red-blue-red-yellow-red-purple etc. are entered, which themselves then repeated as desired. The total circulation time is For example, in a 16-station color pass 320 seconds. This means that between two color stations a time interval of 20 seconds.

The device 10 of the invention now calculated using the Computer subunit 16a and / or with the help of the computer subunit 16b between each two adjacent color stations a plurality of Zwischenfarbstationen, in the aforementioned example, for example nine intermediate stations. This way, about every 2 seconds for generating a color transition from the computer subunits 16b and 16a and the storage unit 14, respectively Control information via the signal line 13 individually addressed to all Ballasts sent. The device 10 thus enables a Fine grading and almost constant sending of new brightness values within short intervals. This allows a precise, predictable color transition without affecting the in the Ballasts stored fading times are used got to. In this context, it should be noted that DALI terminals, ie ballasts operating according to the DALI protocol, typically a storage space for a so-called "fading time" that ensures that the electronic Ballast sent target brightness level values within the set fading time can be achieved. Because the individual Ballasts, however, different, stored dimming curves is a precise, predictable color transition using the individual dimming curves stored in the ballasts not achievable.

The device 10 according to the invention thus also enables the Using different ballasts, for example different manufacturers, without any inaccuracies in the Color transition arise.

The inventive device sends in the event that Color changes are desired, from the computer subunit 16b or from the memory unit 14 information about new, to be reached Brightness values to the ballasts no later than every 10 seconds, preferably at least every 5 seconds and more preferably at the latest every 2 seconds. In this way, the Color changes from a human eye within this Time interval practically can not be resolved. Another Fine-tuning is no longer required.

It should be noted in this context that the Computer subunit 16b and the memory unit 14 in the Embodiment a common unit, in particular a represent small computer.

The inventive device also offers the Possibility that a color transition, ie a dynamic light scene, is individually adjustable with regard to their entire course. One User can individually select and set up each individual color station this way a color passage of any order and sequence put together.

It should be emphasized that the input unit 15 after entering the individual color values and the color passages from the device 10 through Disconnecting the USB interface connection 18/19 can be disconnected. The lighting information, such as a specific one Farbgang, are stored on the memory unit 14 and can be called from the control unit 20. In particular, there is the Possibility, via the input unit 15 a certain color to assign a specific title, which after saving the Farbganges in the memory unit 14 on a display of Control unit 20 can be seen and retrieved there without further notice can be.

The following is intended to clarify how a change in the Color values actually achieved:

Starting from an output color value, ie an actual state, which the lamps occupy at a certain time, this output color value is denoted by A and points For example, the color triplicate values (255, 0,0) represent the Brightness level values of a red, a green and a blue Lamp on. The luminaire shines in accordance with the output color value A thus red light off.

Starting from the output color value A, let a target color value Z, which has the color triplets 0, 255, 0. The destination color value corresponds to green light, since only the green light is on.

In the event that a user selects the target color value Z and the device 10 is to reach the target color value Z starting from an output color value A, a target time t _z of, for example, 500 seconds is provided for this purpose. The device 10 thus has 500 seconds to transfer the color emitted by the luminaires from the output value A to the target color value Z. For this purpose, the device 10, in particular the computer units 16a or 16b, automatically calculates a plurality of intermediate color values, preferably 254 intermediate color values. The device then sends every 2 seconds a new color value to the individual ballasts associated with the lamps.

Starting from the output color value A is within the first 2 seconds, for example, to that of the red lamp associated Ballast targets the new brightness level value 254 transmitted. At the same time within the first 2 seconds, too Targeted to the ballast associated with the green lamp the brightness level value 1 is transmitted.

Within the following 2 seconds is then on the ballast associated with the red lamp Brightness level value 253 individually addressed and sent to the green lamp associated ballast the brightness level value 2 assigned. In this way, within the 500 seconds, 250 times every single ballast addressed and with a new one Brightness level value faced.

Of importance is still that the lights or participants of the Network in any way to groups are summarized. So is e.g. a first dynamic light scene in the form of a color transition definable, which is a first group of luminaires or participants of the Network appeals, and a second dynamic light scene in shape a color passage definable, which is a second group of lights or participants of the network.
