Description

Addressing method for a light-emitting means, in particular light-emitting diodes

The invention relates to addressing methods for a luminous means according to the preamble of patent claim 1 and to a lighting system having at least one luminous means according to the preamble of patent claim 10.

Technical area

Such methods are used to control operating devices for lighting and are used in lighting systems to turn on and off bulbs by means of a central control unit and adjust the brightness. Usually, the bulbs are driven by operating devices. The operating devices are grouped together and can be controlled by one or several central control units. The term bulbs refers to both gas discharge lamps and halogen lamps or light-emitting diodes (LEDs, organic or anorganic). Such a light source can be arranged individually or together with other light sources in a luminaire, which may also contain the operating device. A special form of the luminaire are the so-called energy-saving lamps, which, among other things, have a light means (for example light-emitting diodes or gas-discharge lamps), control electronics and a base. State of the art

According to the prior art operating devices are addressed by the fact that the connection between the lamp and the operating device is interrupted. This interruption is detected by the operating device and this operating device takes over the current address to be given by the central control unit. This type of addressing requires a lot of time and effort, because during the installation of the entire lighting system each lamp must be separated.

Although there are already methods for automatic address assignment, for example by random number, but in large lighting systems require a lot of time and it can lead to many duplicate addresses. The avoidance of these double addressing requires a high time and computational effort according to the known prior art.

Presentation of the invention

It is the object of the invention to provide an addressing method for a light-emitting means, in particular light-emitting diodes, wherein the light-emitting means are controlled by at least one operating device depending on commands of a central control unit, characterized by the following steps: putting the operating devices in an addressing mode, reading the respective in the operating device stored preset address by the operating device, causing a modulo operation by the central control unit, wherein an operand for the modulo operation is specified, performing the modulo operation with the preset address and the predetermined operand and storing the result as newly assigned address of the operating device.

This object is achieved for a method according to the invention by the characterizing features of claims 1 and for a generic device e.rfindungsgemäß by the characterizing features of claim 10.

Particularly advantageous embodiments of the invention are described in the subclaims.

The invention also relates to a lighting system with at least one light source, wherein the light source is controlled by at least one operating device depending on commands from a central control unit, and the operating devices have an address, wherein the calculation of the address to be given to the operating device due to a modulo operation he follows .

The invention will be explained with reference to an embodiment of an operating device for a light source.

The invention is based on an embodiment of a lighting system BA with a central control unit 12, a control unit 10, via the control unit 10 to the network coupled operating devices 1, 1 ', 1'',l' ^x , l ' ^y and other control devices 11th , 13, 14 explained.

The present invention can be applied to all types of lighting apparatus. In this case, the use of very different light sources is possible, it can be used in particular inorganic or organic light emitting diodes or gas discharge lamps or halogen lamps. The operating devices 1, 1 ', 1'',l' ^x , l ' ^y , the central control unit 12 and the control unit 10 are part of a lighting system BA.

In addition, further control devices 11, 13, 14 may be connected to the bus line 21.

The various controllers 11, 13, 14 are also referred to as actuators and can be various sensors such as motion or brightness sensors but also by a user controllable actuators such as switches, buttons or touch-sensitive screens with a user interface for lighting control.

The bus line 21 is designed as a two-wire data line, which transmits a control signal as a digital signal with a low DC voltage. For example, a data transmission according to the DALI standard is transmitted via the bus line 21. The

Interface circuits of the operating devices 1, 1 ', 1'',l' ^x , l ' ^y , the central control unit 12 and the control unit 10 are capable of receiving digital control commands, for example according to the DALI standard.

It should be noted that the data transmission of the control commands via the bus line 21 does not have to be wired, but it can be transmitted for example wirelessly via a radio link or via a power line communication (PLC) via the power grid 20. Standardized transmission methods analogous to the DALI standard for Wired data transmission exist, wherein according to the inventive method, a modified data transmission via the same bus line 21 can take place. The central control unit 12 can control single or multiple operating devices 1 of light-emitting devices via the bus line 21, wherein they can receive and also send out digital control commands. In the case of a corresponding switch-off command on the bus line 21, which is received and evaluated by the control unit 10, the control unit 10 can disconnect the connected operating devices 1 from the grid in order to reduce their power consumption to 0. Thereby, the operating devices 1 are transferred from the operating state to a standby state. The control unit 10 continues to monitor the bus line 21 to control commands and can save them.

The grid connection and network separation of the operating devices 1 from the mains supply is performed by a network breaker 5. This network breaker 5 can

Switch such as a semiconductor switch or a relay. The mains breaker 5 can be integrated into the control unit 10 or else be driven by a control output of the control unit 10.

The control unit 10 can control a plurality of independent network connections and thus independently of each other operating devices 1 by being able to control or integrate several network connections. The independent operating devices 1 can be distinguished from each other by different addresses. The power supply of the control unit 10 and the control units 11, 13, 14 and the central control unit ^ 12 can be done via an integrated into the control unit 10 bus supply. The bus supply can feed the bus line 21 by applying a transmission according to the so-called 'active low' principle. In such a transmission is permanently a level of, for example, 12V, as long as no data is transmitted. In the case of data transmission, the level for transmitting a bit is pulled to a level below 2V, for example.

In this way, a permanent voltage is applied to the bus line 21 and thus a supply of the control units 10 and 11 via the bus line 21 is possible.

It may have the control unit 10 via its own power supply, which is coupled directly to the mains supply.

The central control unit 12 can query the state of the operating devices 1 via the bus line 21. Furthermore, the central control unit 12 also via directly connected buttons or switches, through an interface to a programming device by a

Touchscreen or other settings can also be configured and controlled directly by a user. Due to the direct control option, the user can also specify control commands, such as brightness values.

Within the lighting system BA with at least one light source, the bulbs, by at least an operating device 1, 1 ', 1'',l' ^x , l ' ^{y be} controlled depending on commands from a central control unit 12, have an address.

The calculation of the operating devices 1, 1 ', 1'',l' ^x , l ' ^γ to be given address A (also called short address A) can be done due to a modulo operation. Each a preset address L can ^γ already at delivery of the operating devices 1, 1 ', 1'',L' ^x, L 'in the operation of devices 1, 1', 1 '', L ^'x, L' ^y be stored. This default address L (also called Long Address L) can, however, for a plurality of operating devices 1, 1 ', 1'',L' ^x, L ^'y have been assigned, or for communication on the bus line 21 may be inadequate. For a trouble-free and user-friendly control of the lighting system BA, it is necessary that each

Operating device 1, 1 ', 1'',l' ^x , l ' ^y or each light source has a unique, only once assigned address.

The possible sequence of addressing based on a calculation based on a modulo operation will be described with reference to FIGS. 2 to 4.

FIG. 2 shows an embodiment of the structure of an inventive transmission of an address.

According to the addressing method according to the invention for a luminous means, wherein the luminous means are driven by at least one operating device 1, 1 ', 1'',1' ^x , 1 ' ^{γ in} dependence on commands of a central control unit 12, the following steps are carried out: Operating devices 1, 1 ', 1'',l' ^x , l ' ^y in an addressing mode, - reading out the ^γ respectively in the operating device 1, 1 ', 1'',L' ^x, L 'stored preset address L by the operating unit 1, 1', 1 '', L ^'x, L' ^y,

Initiating a modulo operation by the central control unit 12, an operand N being specified for the modulo operation,

Carrying out the modulo operation with the preset address L and the predefined operand N and storing the result as newly assigned address A of the operating device 1, 1 ', 1'',1' ^x , 1 ' ^y -

FIG. 3 shows an embodiment of the structure of an inventive transmission of an address for the detection of address conflicts.

In a further step, the central control unit 12 to query the possible addresses A and check transmits an acknowledgment for a particular address more than one operating unit 1, 1 ', 1'',L' ^x, L ^'y. This method can be used to detect address conflicts.

For example, the lowest part of the integer quotient of the division L / N can be sent back. Transmission errors occur when two or more operators answer at the same time, thus overlapping the answers. If no transmission error has been detected, the central control unit 12 may cause the operating device (s) to send the next part of the preset address L and check the

Answer again regarding a transmission error. This process is repeated until either one Transmission error was detected, or the entire preset address L was sent.

If a transmission error has been detected, the central control unit 12 terminates this checking process and notes the address A for the step of the renewed modulo operation with the preset address L but after a modified method for avoiding address conflicts. If no transmission error was detected at the end, this is not a double address. The address A is classified as valid by the control unit. By a further command, the central control unit 12 for the device with this address A ends the addressing process. Now, the checking operation for the remaining addresses A is performed according to the same method.

FIG. 4 shows an embodiment of the structure of an inventive transmission of an address for avoiding address conflicts.

According to the luminary addressing method of the present invention, in a further step, the central control unit 12 may cause a re-modulo operation with a newly specified operand N 'for the modulo operation for the addresses A more than one feedback, and then the corresponding operating devices 1, 1 ', 1'',l' ^x , l ' ^y again carry out a modulo operation with the preset address L but according to a modified method and store the result as newly assigned address A. According to the addressing method according to the invention for a luminous means, in a further step, the central control unit 12 can also cause a renewed modulo operation with the operand N for the addresses A more than one feedback, and then the corresponding operating devices 1, 1 ', 1 can '', 1 ^{/ X} , l ' ^y again carry out a modulo operation with only a part of the preset address L (ie with a changed method) and store the result as newly assigned address A. The part of the preset address L can be determined by dividing L by N.

Furthermore, the central control unit 12 can query and check the possible addresses A until no more than one operating device 1, 1 ', 1'',1' ^x , 1 ' ^γ sends a return message for all possible addresses.

To check whether sends a response for a particular address more than one operating unit 1, 1 ', 1'',l' ^x, l ^'y, the operating device 1, 1', 1 '', l ^'x, l' can ^γ send with the currently called address as a response at least part of their stored preset address L.

In a further step, the central control unit Ϊ2 can evaluate the responses and check for transmission errors.

The renewed modulo operation can be carried out with a new predefined operand N '.

The re-modulo operation can be performed with a changed combination of the operands L, N, N 'or based on an additional pre-calculation. The operating devices 1, 1 ', 1'',l' ^x , l ' ^γ can communicate according to the DALI standard.

Thus, there is lighting system BA with at least one light source, wherein the operating devices 1, 1 ', 1'',l' ^x , l ' ^γ can be put into an addressing mode and in each of the operating device 1, 1', 1 '', l ' ^x , l' ^γ stored preset address L can read.

The operating devices 1, 1 ', 1'',l' ^x , l ' ^y can perform a modulo operation with the default address L and the predetermined operand N upon initiation of a modulo operation by the central control unit 12 and the result as new assigned address A of the operating device 1, 1 ', 1'',l' ^x , l ' ^γ store, where an operand N for the modulo operation by the central control unit 12 can be specified.

The central control unit 12 can query the possible addresses A and check whether more than one operating device 1, 1 ', 1'',1' ^x , 1 ' ^γ sends a response for a specific address.

The bulbs can be addressed according to this invention. Usually, the individual bulbs are each driven by a control gear. But it is also possible, especially in light-emitting diodes, that several lamps can be controlled independently of each other via one and the same operating device. Therefore, in this case the individual light sources can be assigned different addresses in order to be able to control them independently of one another.
