LIGHT FIXTURE
A light fixture according to the present patent s application is any light fixture capable of illuminating or lighting a building surface, a part of a building surface, an object or an outside surface. At the same time the invention relates to light.fixtures capable of backlighting a surface like a navigation light fixture or decor light fixture.
LO The invention is based on a light fixture as shown and described in post-published.German patent applications DE 2005 009 228.4 and DE 10 2005 024 449.1 of applicant. Both of these patent applications are herewith completely included in the content of the present patent application, also for reference to individual or ~s several features.
From the post-published patent applications a light fixture with a memory is known, in which information concerning the light: fixture can be recorded. This may be for example explicit identifiers like a serial number, or data regarding the type of 20 light head, for example the type or color of the light source or of plural light sources, regarding the electrical hookup, the production date, etc. A light head according to the present patent application is that part of the light fixture that contains at least one light source,'in other words a lamp. Dependant on the 25 type of light source used, the light head is typically also provided with reflectors, lenses, color filters, housing portions, light fixture bases, etc. A light head according to the present - 1 _ patent application can also be a standard, self-contained light fixture that can be connected to a controller of a light fixture control system by means of an installation unit.
The light head can have a-housing that is separate from the installation unit or provided in a coauaon shared housing together with the installation unit. An installation unit according to the present patent application is particularly but not exclusively an operating unit for the light head, for example an electrical power-supply circuit. The.installatiori'unit, however, _o can also be a separate device from the operating=unit.
Preferably the installation unit can be connected with the signal line that connects the light fixture with a controller of a light fixture network. The controller can.operate thelight fixture tr.ansmitting control signals corresponding to the requests 13 of-the user or processing an electronic control program, for example switch on or off at certain times or, if differently colored light sources are provided, it can also make the color selection.
The data written in the installation meawry concerning 20 the :Light head can be taken into account when the light fixture is controlled. This is already noticeable during the installat-ion of the light fixture network, for example when the controller can use the data concerning the light head in order to establish, by mapping comparison between for example a transmitted.article number Zs and a data base in the control, which kind or which type of light-fixt,ure is connected.

When the light fixture is controlled,.for example also light source-related data, like ~or example the
- 2 -maximum achievable light current or the exact color that can be gener;ated by the light source, can be taken into account so that particularly exact color values can be achieved.
In certain applications it may be requested-to replace an s existing light fixture with a new light fixture. This can be necessary if the existing light fixture is defective or if a new light fixture with different characteristics is to be installed, for example if a downlight lighting a floor area is to be replaced by a spot light distribution with a wall-washer light.
Starting from this point the invention is based on the object to further develop a light fixture according to the preamble of claim 1 such that replacement of the light fixture is simplified.
The invention solves this object with the features-of ~s claim 1, particularly with those of the characterizing clause and is accordingly characterized in that to.the light head is associated with at least one light-head memory that is"separate from the installation memory and that contains light-head related data, the data can be read from the light-head memory and written into the installation memory.
The priaciple of the invention is basically that the light head has its own light-head memory. This light-head memory is a separate memory from the installation memory.
While the installation memory is preferably provided in an operating unit for the light head, the light-head memory is directly associated with the light head. Light-head-specific data is written in the light-head memory, particularly in the factory

The priaciple of the invention is basically that the light head has its own light-head memory. This light-head memory is a separate memory from the installation memory.
While the installation memory is preferably provided in an operating unit for the light head, the light-head memory is directly associated with the light head. Light-head-specific data is written in the light-head memory, particularly in the factory
- 3 -during production. This way, after the light fixture is produced, it contains for example data regarding the product number of the light head, the type of light source used, its color, if necessary also data regarding the reflectors used, etc.
Afterward the light head can.be connected to.an installation unit having an installation memory, either in the factory, at the client's, or during installation at the application.
site.. The installation unit is for example the operating unit for the light head.
io As a result of a connection between the light head and the installation unit, for example by.an electric plug connection, in particular by a cable, the data in the light-head memory can be read arid transferred to the installation memory. The installation memory thus knows which light head is connected to it.
3.5 The data now transferred to the installation memory can be transferred to the controller of the light fixture rietwork by a signal line. The controller can then use the.received light-head-related data for controlling the light fixture, if necessary, also during the installation process.
so if only a part of the light head is defecti.ve and a complete replacement of the,light head is necessary, or if the existing light head is to be replaced by a modified light head with different light-technical characteristics, the light head can be removed without problems from the installation unit and a new light 25 head can be connected to the installation unit. When the connection between the new light head and the remaining installation unit is established , the light-head memory ofthe.new _ 4 light head can be read as well and the data can be transferred to the installation memory. Henceforth, the controller can access the light-head-related data of the new light head again.
with the light fixture according to the invention a s particularly easy installation of the replacement light head or of a new.light head with different light-technical characteristics is possilble, without the.whole light fixture having to be replaced.
it is enough.to replace the actual light head. The installation unit can remain in place. Thus, the effort necessary for replacing .0 the.light head is distinctly reduced.
At the same time the controller is supplied with new light-head-related data in a very elegant manner. If necessary, a new installation can be avoided, since the installation unit remains in its original application site and thus the controller can memorize the positions of the installation units. The new light:-head-related data therefore can be simply transmitted to the contr,oller without great effort.
The light fixture according to the invention also reduces the effort necessary for storing parts of the light fixtures and 20 for the installation of the light fixture. According to the inveiat;ion it is possible to revert to standardized installation units that are produced completely independently from the light heads and can each be provided with an installation memory. in addition to the light-head-related data the installation memory can 25 also contain installation unit related data, for example an unique identifier for-the installation unit.
According to an advantageous-embodiment of the invention the iiistallation unit can be connected to the controller of a control system for several light fixtures through a signal line.
The data written in the installation memory can be transmitted to s tihe controller, in particular over the signal line. Thus, a particularly elegant reading of the installation memory and furnishing of light-head related data to the controller can be carried out. As soon as the controller has received_the light-head-related data, the controller can use this data for controlling Lo the light fixtures, before or evea before during the iastallation routine of the light fixtures.
According to an advantageous embodiment of the invention the data written iri the installation memory can be taken into.
account when the light fixture is controlled. Thus the 1s installation unit might be provided with a adjustment unit that adjusts the control commands.received by the controller in accordance with the light-head-related data. As far as the possibility of correcting control signals is coricerned reference is made to the post-published patent applications.in order to avoid 20 repetition.
A reading of the data from the light-head memory and a writing of the data into the installation memory preferably.occurs during or-after a connection between.the 1-ight head and the installation unit is established. Such a connection can for 25 example be established by an electrical line, in particular a plug connection. A reading of the light-head memory can for example be carried out as soon as the installation unit, that is in particular -the operating unit for the light head has been supplied with operating voltage. A transmission of the light-head-related data from the light-head memory to the installation memory thereby can.
occur over data lines or over existing power supply lines, for example over corresponding power-line communication signals.
Finally also a contact-free reading of the light-head memory from the installation memory, f-or example via electromagnetic waves can be carried out.
A reading of the data contained in the light-head memory .o can also be carried out after a,control comsand is received that is sent from.the controller to the installation unit.
According to an advantageous embodiment of the invention the installation unit is an operating unit for the light head. in part3.cular the installation unit is an electrical power-supply circuit for the light head. Thus, it is possible to=use stai4dard operating units. This only requires a minor modification of the memory of the.operating unit that has to be capable of receiving the :Light-head-related data from the light-head memory accordingly to the invention.
20 According to an advantageous embodiment of the invention a connection between the light head and the installation unit by electrical lines can be removeably established. In the case of the installations unit being the operating unit for the light head, the light head and the installation unit are connected to each other by as power supply lines. The operating unit ensures that the light source or the light source at the light head is supplied with the necessary-operating voltage at the right moment. The existing power supply lines can be used for transmitting the light-head-related data from the light-head memory to the installation memory.
In this casethese data signals can be modulated on the power supply lines.
s Alternatively, data lines separate to the existing power supply lines that allow a transmission of data from the.light-head memory to the installation memory can exist between the light head and the installation unit.
Finally also a wireless connection between the 0 insta:Llation memory and the light-head memory can be provided that-.
allows for example.activation of the light-head memory.by means of electromagnetic waves.
The light fixture according to the invention haB several light heads according to an advantageous embodiment of the Ls invention that can be connected to a shared installation unit. A
single installation unit with a shared installation memory thus.can store: data from several light heads. As the different light heads are preferably provided with own light head memories, it is particularxy advantageous if the installation memory can store the 20 . data from the plurality of light head_memories. Thus a1l the data regaacding the plurality of light heads that the installation.memory has received from the plurality of light-head memories can be integrally or at least centrally transmitted.to the controller of the network.
25 In a particular advantageous embodiment of the invention the light head is composed of several elements. The light head can for example be composed of a reflector, a light source, a'cover glass, a housing part, a light fixture base, etc. The plurality of elements of a light head have their own light-head memories.
Thus a reflector memory can be associated with the reflector that contains data regarding the type of reflector. For example, the s reflector memory might contain the data that a spot reflector is used.
The light source can have its own light source memory that is for example arranged in a light fixture base for the light source. The light-source memory can contain data regarding the Lo kind of light source to be stored in the light-fixture base.
Finally a part of the light head, for example a support for a cover glass can also contain its ovm cover-glass memory. It can contain data regarding the kind of cover glass, for example clear or diffusely dispersive cover glass, or regarding whether a colored cover glass or a color filter are used..
The individual memories, as for example the reflector memory, the light fixture base memory and the cover-glass memory can transmit their data to the installation memory. The installation memory can either itself collect the data received and 20 refer to this data when the light source is controlled. In this situation an adjustment unit mentioned before could use this data.
Alternatively the installation memory could transfer the data. received from the individual memories of the light head elerLents tb the light fixture network, so that the controller can 25 then use this data or take it into account when the light fixtures are controlled.
Further advantages of the invention result from the not cited subclaimsas well as from the following description of several exemplary embodiments illustrated in the figures'. Therein:
FIG. 1 is a schematic overview, partially similar,to a s block diagram, of an embodiinent of a light fixture according to the invention in a lateral view with a light head and an installation unit as well as a part of the network;
FIG. 2 is a second embodiment of a light fixture according to the invention in an illustration similar to FIG. 1, .0 wherein part of the network is left out;
FIG. 3 is a.schematic block diagram of a third embodiment of a light fixture according to the invention;
FIG-4 is a fourth embodiment in an illustration similar to FIG. 3; and ts FIG. 5 is a fifth embodiment of a light fixture accordiag to the invention.
The light fixture as a whole according to the invention is indicated with 10 in-the figures and is to be described in detail in the following. It should be noted that for reasons of 20 clarity similar parts or elements, or parts or elements with comparable functions are indicated with the same reference signs even in different embodiments, sometimes with lower-case letters added.
FIG. I shows a light fixture 10 according to the 25 invention with a light head 11 and an installation uriit 12 in a schematic local sectional view. The surrounding dotted line L.
indicates that the light head 10 [translators note: should be 111 togethe:r with the installation unit 12 are referred to as a light fixture according to the invention.
The light head 11 comprise$ all the assemblies of a.light fixture providing light-technical characteristics, that is a housing 13, a reflector 14, a light source 15, also referred to as.
a lamp, and a light.fixture base 16. In the light path, only schematically indicated with the shown arrows,..are provided for example diffuser elements 17a or 17b influencing the light transmission, which can also be lens elements, clearly or diffusely dispersing cover glasses, color filters, etc.
The light head 11 thus can be produced and constructed as a generic light head.
The installation unit 12 is basically formed according to' as a standard operating unit, for example as an electrical power-s' supply circuit. The installation unit 12 can thus contain a transformer, a dimmer and/or other electrical or electronic components that are arranged between the light head il and the actual network established by a signal line 24.
The light fixture 10 is connected to a schernatically !o shown control unit 23 by a signal line 24. The controller can send out a plurality of control commands through the signal line 24, whic'.h reach the installation unit 12. Other light fixtures, too, as for example the light fixtures 21 and 22 shown, can be connected to the network. Thus, the controller 23 can control numerous light 25 fixtures like a control center. The signal line, for example, can trar,Lsmit control signals according to the DAt,I-protocol.
The light head 11 is connected to the installation unit 12 by a connecting line-19. The connecting line 19 initially serves in a standard manner to transmit the operating voltage necessary for the operation of the light source 15. Therefore, in the embodiment according to FIG. 1 the installation unit 12, ergo the operating unit, can particularly transmit the necessary and requYred operating voltage according to the control signals received by the controller 23.
In FIG. 1 the connection of the installation unit 12 to.
~o the power supply line supplying the installation unit 12 with operating voltage is not shown for reasons of clarity. FIG. 1 shows only the signal-technical connection between the light head 11, the installation unit 12 and the controller 23 in the form of the connecting line 19 and the signal line 24.
ls An installation memory 20 is provided at the installation unit 12 that may contain light-head-related data. In a light fixture described in the post-published patent application the.
installation memory 20 after manufacture of the whole light fixture' already contains data regarding the connected light.head 11.
. T2;us, the installation memory 20 can contain data regarding the product number of the light head 11, the number and type of.the light sources 15 and, if necessary, also a specific identifier of -the light fixture 10. The data contained in the memory 20 can be transmitted to the controller 23 by the.-signal line 24. This data can be used or taken into account when the light fixture 10 is controlled. .
According.to the invention the light head 11 of the embodiment in FIG. 1 is provided with the separate light-head memory 18. In the light-head memory 18 are stored light-head-related data, for example data regarding the number and type of s light source 15, regarding the type of reflector 14, regarding the number and type of the diffuser or lens elemeats.17a and 17b, etc.
In addition, the memory 18 can also include an explicit identifier.
in form of a serial number and/or an article-number.
The installation unit 12 and the light head 11 can be Lo produced independently from each other. A connection of these two parts 11, 12 does not have to be carried out directly after the production, but can also be carried out at the application site, on the construction site. 0nly. when the light head 11 and the installation unit 12 are connected to each other by the connection 15 19 isi the light-head-related data contained'in the light-head memory 18 transmitted to the installation meaiory 20 of the installation unit 12. The installation memory 20 stores this data and, if necessary, can transmit it to the controller 23 by the signal line 24. Alternately an adjustment unit can be provided in 20 the.:installation unit 12 that takes the light-head-related data into account when it receives control commands from the-controller 23. The latter is particularly advantageous if the data contained in the light-head memory 18 and transmitted to the installation memory 20 contain data regarding specific characteristics of the 25 light source, as for example maximal light current or exact light color, age of the light source, etc.
The connection 19 in-the embodiment according to FIG. 1 is established by a cable that both contains lines for transmitting the operating voltage from the installation unit 12 to the light head 11 and for transmitting data from the light-head memory.18 to the installation.memory 20. For example, the connecting line 19.
can be a four-conductor or five-conductor cable. The connecting line 19 therefore can contain for example three standard conductors for the transmission of operating voltage, such as for i.nstance power, neutral, and ground, as well as two additional conductors in .0 ordex- to provide a twin-wire signal line between the light head 11 and the installation unit 12. Alternatively the connecting line 19 can also contain.a different number of conductors. It is also possi_ble that data transfer for the transmission of the data to be read from the light.-head memory 18 to the.installation memory 20 L5 occurs by signals that can be modulated on the existing power supply line of the connection 19,. Finally the connecting line 19 can also be composed of two separate cable connections, a first cable connection serving to supply the light head 11 with operating .voltage and a second connecting cable serving to provide a signal-20 technical connection.
The connection 19-between the light head 11 and the installation unit 12 is removable. A socket 37 at the side of the installation unit and a plug 38 at the side of the light head are only shown in a very schematic manner by which the removability of 25 the connection is to be emphasized.
If the light head 11 is defective and is to be replaced by a new light head 11 or if it is necessary to connect a new light head 11 with modified light-technical characteristics to the installation unit 12, the.removable connection 37, 38 can be disconnected and a new connection established. The newly connected light head 11 has its own light-head memory 18 with data contained therein that contain data regarding this new light head. This new data can be again transmitted to the installation memory 20 after the connection 37, 38 has been established. The installation memory 20 can transfer/transmit this data to the controller 23.
This way, a simple replacement of the light head 11 is possible in the light fixture according to the invention while the insta:Llation unit 12 can remain installed at the application site.
Thus-an additional installation step is avoided in the case of a replacement of the light.head 11. -Since the controller 23 can memorize the position and particularly the identity of the s installation unit 12, for the subsequent controlling.of the new light head 11 a transmission of light-head-related data from the memory 18 to the memory 20 and a subsequent transmission of the data to the controller 23.'are sufficient. No new position data about the newly connected light head 11 has to be transmitted to ao the csontroller since the corresponding position data is already available to the installation unit 12 that remained at the application site.
In an alternative embodiment according to FIG. 2 the light head 11 is composed of a plurality of elements that have 25 their own memories.
in FIG. 2 a base memory 25 for the light source 15 is provided, approximately in the area of the base 16 that 'contains data regarding for example the type of the connected light source 15. The reflector 14 has its own associated reflector memory 26 that contains data.regarding the kind of reflector, for exannple the size of the reflector or an indication whether a spot or wall s washer reflector is used.
Finally, a cover glass memory 27 that contains data regarding what type of diffuser or lens elements are arranged.at the light head 11 is assigned to a diffuser or lens element 17a or 17b or alternatively to the light head housing 13. The cover glass .0 memory_27 can_also contain data regarding, for example, whether a certain color filter or the like is provided.
The three memories 25, 26, 27 are also referred to as light.-head memories according to the.present patent application.
The.t:hree memories can be connected to the memory 20 of the L5 installation unit by individual connector lines. 28a, 28b, and 28c to the shared connecting line 19.. Alternatively separate lines can lead to the installation memory 20 from the three single memories 25, 26, 27.
zt should be noted that all the memories in the.light 20 head 11 and in the installation unit 12 described so far and further to be described can for example.be memories that can.be read electronically, for example like an EPROM memory. Also, every -other possibility to retrievably store data is suitable, for example as. well RP1D circuits, memories.that can be read optically 25 or electromagnetically, magnet memories, etc.
If a light fixture 10 according to the invention modularly out of single elements 13,.14,..15, 17a, 17b according to the embodiment of FIG. 2, during manufacture of the light head any composition of the single assemblies or components of the light head 1.1 is possible, thus for example any type of reflector 14, light fixture socket 16 or light source 15 and diffuser or lens or color filter elements 17a, 17b that individually were provided with separate associated memories 25, 26, 27 before.the assembly of the-light head 11..
This modularly constructed light-head construction 11 can, if necessary, be recognized as the light head 11 with .0 particular light-technical characteristics only at the application site by the installatibn unit 12 or only by the controller 23 subsequent to transmission of all the light-head-related data to.
the controller 23, and after recognition of the light-technical characteristics of this light fixture 10 can be controlled in an cs opti.nia.l manner.
FIG. 3shows with the help of.an illustration similar to a blockdiagram that the light head 11 can contain a light fzxture.
15 and a light-head memory 18, this illustration being strongly relatted to the embodiment of FIG. 1. The installation unit 12 can 20 be ain operating unit 35 and contain for example:a transformer 30 connecting the light source 15 by a power supply line 32 to the power lines 34. The light-head memory 18 is connected to the memory 20 of the installation unit by a data line 31 that is separate from the power supply line 32. It should be noted that 25 both lines 31, 32 can be in form of twin wires or multiconductor wires.
- 3.7 -The installation unit 12 is connected to the signal line 24. In the installation unit 12 for example an adjustynent unit 29 can be provided that adjusts the control signals received from the controller 23 considering the data written in the installation memory 20 received by the light-head iaemory 18 regarding the light source: characteristics. The adjusting function should be indicated with t:he arrow 39. The adjustment unit 29 influences the operating behavior of the transformer 30. For example the adjustment unit 29 can switch the transformer 30 on or off or control certain 0 operational characteristics.
In the embodiment according to FIG. 3 the light-head-related data read from the light-head memory 18 that are contained in the installation memory 20 can be also transferred to the control unit 23 by the adjustment or control device 29 and the s signal line 24. In this case the control unit 23 can already take into account the characteristics of the light head 11 when the light fixture 10 is installed, so that the adjustment device 29 does not have to carry out an adjustment function in this case, but only a control function.
>.o FIG. 4 shows an embodiment in an illustration comparable to FIG. 3, the separate data line 31 being eliminated and replaced by a radio link 33. The installation memory 20 can read the light-head-related data contained in the light-head memory 18 by electromagnetic waves or a different wireless transmission 25 connection. A reading can for example take place if the light head 11 is so close to the installation unit 12 that a minimum distance is not respected.
FIG. 5 shows an alternate embodiment of a light fixture according to the invention, the operating unit 35 of which is divided into two-parts 12 and 40. The operating unit 35 has a basica:Lly standard operating unit indicated with 40, as well as an installation unit 12 separated thereof.
The standard operating unit 40 is connected in the normal manner to the light source 15 of the light head 11 by a power supply line 32. The installation unit 12 that has an installation rnemory, 20 is connected to the light-head memory 18 by a separate o data line 31 and allows a reading of the light-head-related data.
The installation unit 12 is connected to the network line 24 by a separate connecting line 41 and can transfer'data received from the light-head memory 18 to the controller 23. The installation unit 12, however, in this embodiment is as well associated with the s standard operating unit 40, for example attached to the standard.
operating unit 4g:.- The---tanda-rd-operat-ing--;;,r-3t -d0--has -a-separata--connection 42-to the signal line 24, by which a DALI connection unit 36 can be addressed that in its turn carries out a control function, for example regarding a transformer 30 of the operating ao uait 40.
The light fixture 10 according to the invention can also have an installation unit 12 to which plural light heads 11 are connected, which is not shown in the figures. While any of the plurality of light heads contains its own light-head memory, the 25 installation unit 12 with its installation memory 20 can receive all the light-head-related data from the different light heads and, as required, either directly transmit the data to the controller 23 of the light fixture network or take it into account when carrying out an adjustment function when the light fixtures are coiatrolled.
The light fixture according to the invention allows recognition of a light head or of parts 15, 14, 17a,-17b of a light head :11 by the installation unit 12, for example by an operating unit. if necessary, the installation unit 12 itself can be equipped with the "intelligence" necessary-to recognize the parts of the light head and to assemble them like software.
Alternatively the installation unit 12 can.also have the role of io transmitting the light-head-related data to tlie-controller so that the controller 23 recognizes the light head 11 or the parts.of the light: head 11 and thus can carry out an optimized controlling.
The light fixture according to the f.nvention allows a light: fixture managernent inside of the light fixture. A
is replacement of a light head 11 is possible without associated operating units having to be replaced if the light head 11 and the operating unit 12 have their own memory and if a transmission of data.from the light-head memory to the memory'associated with the operating unit is possible.
20 A reading of the light-head memory.18 or a transmission of the data to the installation memory 20 can be carried out when the light head 11 is connected to the installation.unit 12 or alternatively only when the installation unit 12 is attached to the signal line 24 and connected to the controller 23.
-
Afterward the light head can.be connected to.an installation unit having an installation memory, either in the factory, at the client's, or during installation at the application.
site.. The installation unit is for example the operating unit for the light head.
io As a result of a connection between the light head and the installation unit, for example by.an electric plug connection, in particular by a cable, the data in the light-head memory can be read arid transferred to the installation memory. The installation memory thus knows which light head is connected to it.
3.5 The data now transferred to the installation memory can be transferred to the controller of the light fixture rietwork by a signal line. The controller can then use the.received light-head-related data for controlling the light fixture, if necessary, also during the installation process.
so if only a part of the light head is defecti.ve and a complete replacement of the,light head is necessary, or if the existing light head is to be replaced by a modified light head with different light-technical characteristics, the light head can be removed without problems from the installation unit and a new light 25 head can be connected to the installation unit. When the connection between the new light head and the remaining installation unit is established , the light-head memory ofthe.new _ 4 light head can be read as well and the data can be transferred to the installation memory. Henceforth, the controller can access the light-head-related data of the new light head again.
with the light fixture according to the invention a s particularly easy installation of the replacement light head or of a new.light head with different light-technical characteristics is possilble, without the.whole light fixture having to be replaced.
it is enough.to replace the actual light head. The installation unit can remain in place. Thus, the effort necessary for replacing .0 the.light head is distinctly reduced.
At the same time the controller is supplied with new light-head-related data in a very elegant manner. If necessary, a new installation can be avoided, since the installation unit remains in its original application site and thus the controller can memorize the positions of the installation units. The new light:-head-related data therefore can be simply transmitted to the contr,oller without great effort.
The light fixture according to the invention also reduces the effort necessary for storing parts of the light fixtures and 20 for the installation of the light fixture. According to the inveiat;ion it is possible to revert to standardized installation units that are produced completely independently from the light heads and can each be provided with an installation memory. in addition to the light-head-related data the installation memory can 25 also contain installation unit related data, for example an unique identifier for-the installation unit.
According to an advantageous-embodiment of the invention the iiistallation unit can be connected to the controller of a control system for several light fixtures through a signal line.
The data written in the installation memory can be transmitted to s tihe controller, in particular over the signal line. Thus, a particularly elegant reading of the installation memory and furnishing of light-head related data to the controller can be carried out. As soon as the controller has received_the light-head-related data, the controller can use this data for controlling Lo the light fixtures, before or evea before during the iastallation routine of the light fixtures.
According to an advantageous embodiment of the invention the data written iri the installation memory can be taken into.
account when the light fixture is controlled. Thus the 1s installation unit might be provided with a adjustment unit that adjusts the control commands.received by the controller in accordance with the light-head-related data. As far as the possibility of correcting control signals is coricerned reference is made to the post-published patent applications.in order to avoid 20 repetition.
A reading of the data from the light-head memory and a writing of the data into the installation memory preferably.occurs during or-after a connection between.the 1-ight head and the installation unit is established. Such a connection can for 25 example be established by an electrical line, in particular a plug connection. A reading of the light-head memory can for example be carried out as soon as the installation unit, that is in particular -the operating unit for the light head has been supplied with operating voltage. A transmission of the light-head-related data from the light-head memory to the installation memory thereby can.
occur over data lines or over existing power supply lines, for example over corresponding power-line communication signals.
Finally also a contact-free reading of the light-head memory from the installation memory, f-or example via electromagnetic waves can be carried out.
A reading of the data contained in the light-head memory .o can also be carried out after a,control comsand is received that is sent from.the controller to the installation unit.
According to an advantageous embodiment of the invention the installation unit is an operating unit for the light head. in part3.cular the installation unit is an electrical power-supply circuit for the light head. Thus, it is possible to=use stai4dard operating units. This only requires a minor modification of the memory of the.operating unit that has to be capable of receiving the :Light-head-related data from the light-head memory accordingly to the invention.
20 According to an advantageous embodiment of the invention a connection between the light head and the installation unit by electrical lines can be removeably established. In the case of the installations unit being the operating unit for the light head, the light head and the installation unit are connected to each other by as power supply lines. The operating unit ensures that the light source or the light source at the light head is supplied with the necessary-operating voltage at the right moment. The existing power supply lines can be used for transmitting the light-head-related data from the light-head memory to the installation memory.
In this casethese data signals can be modulated on the power supply lines.
s Alternatively, data lines separate to the existing power supply lines that allow a transmission of data from the.light-head memory to the installation memory can exist between the light head and the installation unit.
Finally also a wireless connection between the 0 insta:Llation memory and the light-head memory can be provided that-.
allows for example.activation of the light-head memory.by means of electromagnetic waves.
The light fixture according to the invention haB several light heads according to an advantageous embodiment of the Ls invention that can be connected to a shared installation unit. A
single installation unit with a shared installation memory thus.can store: data from several light heads. As the different light heads are preferably provided with own light head memories, it is particularxy advantageous if the installation memory can store the 20 . data from the plurality of light head_memories. Thus a1l the data regaacding the plurality of light heads that the installation.memory has received from the plurality of light-head memories can be integrally or at least centrally transmitted.to the controller of the network.
25 In a particular advantageous embodiment of the invention the light head is composed of several elements. The light head can for example be composed of a reflector, a light source, a'cover glass, a housing part, a light fixture base, etc. The plurality of elements of a light head have their own light-head memories.
Thus a reflector memory can be associated with the reflector that contains data regarding the type of reflector. For example, the s reflector memory might contain the data that a spot reflector is used.
The light source can have its own light source memory that is for example arranged in a light fixture base for the light source. The light-source memory can contain data regarding the Lo kind of light source to be stored in the light-fixture base.
Finally a part of the light head, for example a support for a cover glass can also contain its ovm cover-glass memory. It can contain data regarding the kind of cover glass, for example clear or diffusely dispersive cover glass, or regarding whether a colored cover glass or a color filter are used..
The individual memories, as for example the reflector memory, the light fixture base memory and the cover-glass memory can transmit their data to the installation memory. The installation memory can either itself collect the data received and 20 refer to this data when the light source is controlled. In this situation an adjustment unit mentioned before could use this data.
Alternatively the installation memory could transfer the data. received from the individual memories of the light head elerLents tb the light fixture network, so that the controller can 25 then use this data or take it into account when the light fixtures are controlled.
Further advantages of the invention result from the not cited subclaimsas well as from the following description of several exemplary embodiments illustrated in the figures'. Therein:
FIG. 1 is a schematic overview, partially similar,to a s block diagram, of an embodiinent of a light fixture according to the invention in a lateral view with a light head and an installation unit as well as a part of the network;
FIG. 2 is a second embodiment of a light fixture according to the invention in an illustration similar to FIG. 1, .0 wherein part of the network is left out;
FIG. 3 is a.schematic block diagram of a third embodiment of a light fixture according to the invention;
FIG-4 is a fourth embodiment in an illustration similar to FIG. 3; and ts FIG. 5 is a fifth embodiment of a light fixture accordiag to the invention.
The light fixture as a whole according to the invention is indicated with 10 in-the figures and is to be described in detail in the following. It should be noted that for reasons of 20 clarity similar parts or elements, or parts or elements with comparable functions are indicated with the same reference signs even in different embodiments, sometimes with lower-case letters added.
FIG. I shows a light fixture 10 according to the 25 invention with a light head 11 and an installation uriit 12 in a schematic local sectional view. The surrounding dotted line L.
indicates that the light head 10 [translators note: should be 111 togethe:r with the installation unit 12 are referred to as a light fixture according to the invention.
The light head 11 comprise$ all the assemblies of a.light fixture providing light-technical characteristics, that is a housing 13, a reflector 14, a light source 15, also referred to as.
a lamp, and a light.fixture base 16. In the light path, only schematically indicated with the shown arrows,..are provided for example diffuser elements 17a or 17b influencing the light transmission, which can also be lens elements, clearly or diffusely dispersing cover glasses, color filters, etc.
The light head 11 thus can be produced and constructed as a generic light head.
The installation unit 12 is basically formed according to' as a standard operating unit, for example as an electrical power-s' supply circuit. The installation unit 12 can thus contain a transformer, a dimmer and/or other electrical or electronic components that are arranged between the light head il and the actual network established by a signal line 24.
The light fixture 10 is connected to a schernatically !o shown control unit 23 by a signal line 24. The controller can send out a plurality of control commands through the signal line 24, whic'.h reach the installation unit 12. Other light fixtures, too, as for example the light fixtures 21 and 22 shown, can be connected to the network. Thus, the controller 23 can control numerous light 25 fixtures like a control center. The signal line, for example, can trar,Lsmit control signals according to the DAt,I-protocol.
The light head 11 is connected to the installation unit 12 by a connecting line-19. The connecting line 19 initially serves in a standard manner to transmit the operating voltage necessary for the operation of the light source 15. Therefore, in the embodiment according to FIG. 1 the installation unit 12, ergo the operating unit, can particularly transmit the necessary and requYred operating voltage according to the control signals received by the controller 23.
In FIG. 1 the connection of the installation unit 12 to.
~o the power supply line supplying the installation unit 12 with operating voltage is not shown for reasons of clarity. FIG. 1 shows only the signal-technical connection between the light head 11, the installation unit 12 and the controller 23 in the form of the connecting line 19 and the signal line 24.
ls An installation memory 20 is provided at the installation unit 12 that may contain light-head-related data. In a light fixture described in the post-published patent application the.
installation memory 20 after manufacture of the whole light fixture' already contains data regarding the connected light.head 11.
. T2;us, the installation memory 20 can contain data regarding the product number of the light head 11, the number and type of.the light sources 15 and, if necessary, also a specific identifier of -the light fixture 10. The data contained in the memory 20 can be transmitted to the controller 23 by the.-signal line 24. This data can be used or taken into account when the light fixture 10 is controlled. .
According.to the invention the light head 11 of the embodiment in FIG. 1 is provided with the separate light-head memory 18. In the light-head memory 18 are stored light-head-related data, for example data regarding the number and type of s light source 15, regarding the type of reflector 14, regarding the number and type of the diffuser or lens elemeats.17a and 17b, etc.
In addition, the memory 18 can also include an explicit identifier.
in form of a serial number and/or an article-number.
The installation unit 12 and the light head 11 can be Lo produced independently from each other. A connection of these two parts 11, 12 does not have to be carried out directly after the production, but can also be carried out at the application site, on the construction site. 0nly. when the light head 11 and the installation unit 12 are connected to each other by the connection 15 19 isi the light-head-related data contained'in the light-head memory 18 transmitted to the installation meaiory 20 of the installation unit 12. The installation memory 20 stores this data and, if necessary, can transmit it to the controller 23 by the signal line 24. Alternately an adjustment unit can be provided in 20 the.:installation unit 12 that takes the light-head-related data into account when it receives control commands from the-controller 23. The latter is particularly advantageous if the data contained in the light-head memory 18 and transmitted to the installation memory 20 contain data regarding specific characteristics of the 25 light source, as for example maximal light current or exact light color, age of the light source, etc.
The connection 19 in-the embodiment according to FIG. 1 is established by a cable that both contains lines for transmitting the operating voltage from the installation unit 12 to the light head 11 and for transmitting data from the light-head memory.18 to the installation.memory 20. For example, the connecting line 19.
can be a four-conductor or five-conductor cable. The connecting line 19 therefore can contain for example three standard conductors for the transmission of operating voltage, such as for i.nstance power, neutral, and ground, as well as two additional conductors in .0 ordex- to provide a twin-wire signal line between the light head 11 and the installation unit 12. Alternatively the connecting line 19 can also contain.a different number of conductors. It is also possi_ble that data transfer for the transmission of the data to be read from the light.-head memory 18 to the.installation memory 20 L5 occurs by signals that can be modulated on the existing power supply line of the connection 19,. Finally the connecting line 19 can also be composed of two separate cable connections, a first cable connection serving to supply the light head 11 with operating .voltage and a second connecting cable serving to provide a signal-20 technical connection.
The connection 19-between the light head 11 and the installation unit 12 is removable. A socket 37 at the side of the installation unit and a plug 38 at the side of the light head are only shown in a very schematic manner by which the removability of 25 the connection is to be emphasized.
If the light head 11 is defective and is to be replaced by a new light head 11 or if it is necessary to connect a new light head 11 with modified light-technical characteristics to the installation unit 12, the.removable connection 37, 38 can be disconnected and a new connection established. The newly connected light head 11 has its own light-head memory 18 with data contained therein that contain data regarding this new light head. This new data can be again transmitted to the installation memory 20 after the connection 37, 38 has been established. The installation memory 20 can transfer/transmit this data to the controller 23.
This way, a simple replacement of the light head 11 is possible in the light fixture according to the invention while the insta:Llation unit 12 can remain installed at the application site.
Thus-an additional installation step is avoided in the case of a replacement of the light.head 11. -Since the controller 23 can memorize the position and particularly the identity of the s installation unit 12, for the subsequent controlling.of the new light head 11 a transmission of light-head-related data from the memory 18 to the memory 20 and a subsequent transmission of the data to the controller 23.'are sufficient. No new position data about the newly connected light head 11 has to be transmitted to ao the csontroller since the corresponding position data is already available to the installation unit 12 that remained at the application site.
In an alternative embodiment according to FIG. 2 the light head 11 is composed of a plurality of elements that have 25 their own memories.
in FIG. 2 a base memory 25 for the light source 15 is provided, approximately in the area of the base 16 that 'contains data regarding for example the type of the connected light source 15. The reflector 14 has its own associated reflector memory 26 that contains data.regarding the kind of reflector, for exannple the size of the reflector or an indication whether a spot or wall s washer reflector is used.
Finally, a cover glass memory 27 that contains data regarding what type of diffuser or lens elements are arranged.at the light head 11 is assigned to a diffuser or lens element 17a or 17b or alternatively to the light head housing 13. The cover glass .0 memory_27 can_also contain data regarding, for example, whether a certain color filter or the like is provided.
The three memories 25, 26, 27 are also referred to as light.-head memories according to the.present patent application.
The.t:hree memories can be connected to the memory 20 of the L5 installation unit by individual connector lines. 28a, 28b, and 28c to the shared connecting line 19.. Alternatively separate lines can lead to the installation memory 20 from the three single memories 25, 26, 27.
zt should be noted that all the memories in the.light 20 head 11 and in the installation unit 12 described so far and further to be described can for example.be memories that can.be read electronically, for example like an EPROM memory. Also, every -other possibility to retrievably store data is suitable, for example as. well RP1D circuits, memories.that can be read optically 25 or electromagnetically, magnet memories, etc.
If a light fixture 10 according to the invention modularly out of single elements 13,.14,..15, 17a, 17b according to the embodiment of FIG. 2, during manufacture of the light head any composition of the single assemblies or components of the light head 1.1 is possible, thus for example any type of reflector 14, light fixture socket 16 or light source 15 and diffuser or lens or color filter elements 17a, 17b that individually were provided with separate associated memories 25, 26, 27 before.the assembly of the-light head 11..
This modularly constructed light-head construction 11 can, if necessary, be recognized as the light head 11 with .0 particular light-technical characteristics only at the application site by the installatibn unit 12 or only by the controller 23 subsequent to transmission of all the light-head-related data to.
the controller 23, and after recognition of the light-technical characteristics of this light fixture 10 can be controlled in an cs opti.nia.l manner.
FIG. 3shows with the help of.an illustration similar to a blockdiagram that the light head 11 can contain a light fzxture.
15 and a light-head memory 18, this illustration being strongly relatted to the embodiment of FIG. 1. The installation unit 12 can 20 be ain operating unit 35 and contain for example:a transformer 30 connecting the light source 15 by a power supply line 32 to the power lines 34. The light-head memory 18 is connected to the memory 20 of the installation unit by a data line 31 that is separate from the power supply line 32. It should be noted that 25 both lines 31, 32 can be in form of twin wires or multiconductor wires.
- 3.7 -The installation unit 12 is connected to the signal line 24. In the installation unit 12 for example an adjustynent unit 29 can be provided that adjusts the control signals received from the controller 23 considering the data written in the installation memory 20 received by the light-head iaemory 18 regarding the light source: characteristics. The adjusting function should be indicated with t:he arrow 39. The adjustment unit 29 influences the operating behavior of the transformer 30. For example the adjustment unit 29 can switch the transformer 30 on or off or control certain 0 operational characteristics.
In the embodiment according to FIG. 3 the light-head-related data read from the light-head memory 18 that are contained in the installation memory 20 can be also transferred to the control unit 23 by the adjustment or control device 29 and the s signal line 24. In this case the control unit 23 can already take into account the characteristics of the light head 11 when the light fixture 10 is installed, so that the adjustment device 29 does not have to carry out an adjustment function in this case, but only a control function.
>.o FIG. 4 shows an embodiment in an illustration comparable to FIG. 3, the separate data line 31 being eliminated and replaced by a radio link 33. The installation memory 20 can read the light-head-related data contained in the light-head memory 18 by electromagnetic waves or a different wireless transmission 25 connection. A reading can for example take place if the light head 11 is so close to the installation unit 12 that a minimum distance is not respected.
FIG. 5 shows an alternate embodiment of a light fixture according to the invention, the operating unit 35 of which is divided into two-parts 12 and 40. The operating unit 35 has a basica:Lly standard operating unit indicated with 40, as well as an installation unit 12 separated thereof.
The standard operating unit 40 is connected in the normal manner to the light source 15 of the light head 11 by a power supply line 32. The installation unit 12 that has an installation rnemory, 20 is connected to the light-head memory 18 by a separate o data line 31 and allows a reading of the light-head-related data.
The installation unit 12 is connected to the network line 24 by a separate connecting line 41 and can transfer'data received from the light-head memory 18 to the controller 23. The installation unit 12, however, in this embodiment is as well associated with the s standard operating unit 40, for example attached to the standard.
operating unit 4g:.- The---tanda-rd-operat-ing--;;,r-3t -d0--has -a-separata--connection 42-to the signal line 24, by which a DALI connection unit 36 can be addressed that in its turn carries out a control function, for example regarding a transformer 30 of the operating ao uait 40.
The light fixture 10 according to the invention can also have an installation unit 12 to which plural light heads 11 are connected, which is not shown in the figures. While any of the plurality of light heads contains its own light-head memory, the 25 installation unit 12 with its installation memory 20 can receive all the light-head-related data from the different light heads and, as required, either directly transmit the data to the controller 23 of the light fixture network or take it into account when carrying out an adjustment function when the light fixtures are coiatrolled.
The light fixture according to the invention allows recognition of a light head or of parts 15, 14, 17a,-17b of a light head :11 by the installation unit 12, for example by an operating unit. if necessary, the installation unit 12 itself can be equipped with the "intelligence" necessary-to recognize the parts of the light head and to assemble them like software.
Alternatively the installation unit 12 can.also have the role of io transmitting the light-head-related data to tlie-controller so that the controller 23 recognizes the light head 11 or the parts.of the light: head 11 and thus can carry out an optimized controlling.
The light fixture according to the f.nvention allows a light: fixture managernent inside of the light fixture. A
is replacement of a light head 11 is possible without associated operating units having to be replaced if the light head 11 and the operating unit 12 have their own memory and if a transmission of data.from the light-head memory to the memory'associated with the operating unit is possible.
20 A reading of the light-head memory.18 or a transmission of the data to the installation memory 20 can be carried out when the light head 11 is connected to the installation.unit 12 or alternatively only when the installation unit 12 is attached to the signal line 24 and connected to the controller 23.
