Description

Multiple function/feature selection system, function/feature selection method and emergency luminaire The invention relates to operation mode selection for emergency luminaries. In particular, the invention concerns an improved operation mode selection device for an emergency luminaire, a corresponding operation mode selection method and a io corresponding emergency luminaire.

It is established practice to provide an emergency luminaire such as an emergency converter driving an emergency luminaire with a capability to configure an operation mode of the emergency converter for a specific application. For example, a minimum lighting duration in an emergency mode of operation maybe preselected between 1 hour, 2 hours or 3 hours by using a jumper (three-pin-plug), which maybe set in either one of two different positions on three pins of a duration select device arranged linearly and externally accessible at the housing of the emergency converter. Alternatively, the jumper is omitted from the pins of the duration select device. A microcontroller of the emergency converter determines the presence or absence, and the actual jumper position and then selects the minimum lighting duration accordingly as 1, 2, or 3 hours.

In some application scenarios, a user may benefit from being able to select more operational parameters or functions of the emergency luminaire than just two or three different minimum lighting durations in an emergency mode of operation.

GB 2568320 A discloses a duration selection device for an emergency luminaire attempting to address this issue. The proposed duration selection device comprises a jumper block with four pins arranged in a square layout and accessible for connecting a jumper between two of the pins. Thus, the jumper block provides four possible jumper positions for connecting the jumper, each jumper position providing a different resistance value between an input terminal of a microcontroller circuit of the duration selection device and a power supply terminal of the microcontroller circuit. The pins of the jumper block are connected with the microcontroller circuit, which control specific functional parameters, in particular lighting duration or light emission of the emergency luminaire in the emergency operation mode.

However, the duration selection device disclosed in GB 2568320 A requires arranging the jumper block being externally accessible for configuring the emergency luminaire to the specific application scenario. This results in reduced design freedom for the design engineer due to the necessity of arranging four pins in an exact square layout.

Moreover, manufacturing cost will increase due to the specific jumper block with four pins when compared to the three pins required for the existing emergency converter.

It is an object of the present invention to overcome the above-mentioned disadvantages and to provide a technical solution in order to improve operation mode selection for emergency luminaires.

to This problem is solved by a mode selecting device according to a first aspect, an emergency luminaire in a second aspect, and a method for selecting an operation mode according to a third aspect of the invention.

The first aspect of the invention concerns a mode selecting system for an emergency luminaire. The mode selecting system comprises a mode selecting device and a plug device. The mode selecting device includes a control circuit that comprises at least two input terminals. The control circuit is configured to measure voltages applied to each of the input terminals and to select an operation mode of the emergency luminaire based on the measured voltages. The mode selecting device further includes a jumper unit with at least three socket connectors, and a connecting circuit configured to electrically connect the socket connectors with the input terminals. The plug device of the mode selecting system is configured to connect mechanically with the jumper unit, wherein the plug device comprises at least three plug connectors configured to connect electrically with the at least three socket connectors. The mode selecting system is characterized by the plug device comprising at least one resistor, wherein the plug device is configured to arrange the at least one resistor to connect electrically two of the plug connectors.

The combination of a mode selecting device and a plug device enables to use an existing three-pin mode selecting interface at a device and to increase the number of selectable operation modes for the device equipped with the mode selecting system beyond the currently available number of operation modes.

The dependent claims define further advantageous embodiments of the invention.

The mode selecting system according to an advantageous embodiment has the control circuit comprising at least two analogue-to-digital converter circuits (A/D converter). Each analogue-to-digital converter circuit is configured to convert an analogue voltage applied to one of the input terminals to a digital signal.

Many control circuits in switched mode power supplies for lighting applications are implemented using microcontroller circuits, which already include two or more A/D converter circuits and corresponding A/D converter input terminals. Thus implementing the control circuit for the mode selecting device is possible without adding further hardware to the emergency luminary.

ro The mode selecting system may be configured to select the operation mode of the emergency luminaire using a pre-stored selection table.

The look-up table provides an efficient and reliable possibility to translate a combination of measured voltage values in digital format into a set of control parameters for controlling the emergency luminaire. A look-up table may be implemented in either hardware or software depending on the application.

According to an embodiment, the control circuit of the mode selecting system is configured to select the operation mode including at least one of selecting an operation parameter of the emergency luminaire and selecting an operation function of the emergency luminaire.

Operation mode selection is of particular importance during installing and commissioning of emergency luminaires, which comprises setting operation parameters, for example an emergency lighting duration, a battery chemistry, or operation functions, such as reading out log data from a log data memory. The invention increases the number available options for selecting operation parameters and operation functions.

The control circuit can be configured to select the operation mode including at least one of an activation or deactivation of an integrated DALT power supply function of an emergency converter that is configured to drive the emergency luminaire. Selecting the operation mode may alternatively or additionally comprise selecting a light output level of the emergency luminaire, selecting a battery chemistry of an energy storage device that is connected to the emergency luminaire, selecting a service mode of the emergency converter, in particular a black box read-out mode of a memory unit, of the emergency converter, and/or selecting operation of the emergency converter in a maintained mode or non-maintained mode of operation.

The increased number of operation modes which may be controlled by the controlled circuit is particular advantageous in emergency lighting applications, which require specific adaptations to different batteries, different lighting durations and light levels in each specific application scenario. The selection of the required operation parameters and operation functions is particular advantageous with the proposed mode selection device.

In an advantageous embodiment of the mode selecting system, the plug device is to selectable from a set including a plurality of plug devices, each plug device of the plurality of plug devices comprising an arrangement of the at least one resistor between the at least three plug connectors that differs from other plug devices of the set.

The set of plug devices from which a plug device for a specific customer may be selected according to the customer's demand and in return for a corresponding license fee improves marketing possibilities of tailoring the same product to different customers by providing a corresponding plug from the set of plugs.

The mode selecting system according to an embodiment comprises the plug device having three plug connectors.

The number of different operation modes for an existing duration select system with three pins is increased to six operation modes.

In an embodiment of the mode selecting system, one of socket connectors is connected with a DC voltage supply.

The connecting circuit of the mode selecting system comprises a plurality of resistors configured to electrically connect the at least three socket connectors with a DC voltage supply and a device ground of the mode selecting device.

The complexity and cost of the plug device does not significantly increase beyond the current plug device, which may use a short circuit (bridge) between two of the plug connectors instead. Nevertheless, the plug device offers increased possibilities to differentiate electrically when connected to the mode selection device.

In a second aspect, the invention refers to an emergency luminaire, which includes a mode selecting system according to one of the preceding claims.

A method for selecting an operation mode for an emergency luminaire using a mode selecting system according to the third aspect of the invention uses a mode selecting device that includes a control circuit, which includes at least two input terminals, a jumper unit that includes at least three socket connectors, and a connecting circuit electrically connecting the socket connectors with the input terminals. The mode selecting system further comprises a plug device connected mechanically with the jumper unit, wherein the plug device comprises at least three plug connectors to connecting electrically with the at least three socket connectors. The mode selecting system is characterized by the plug device including at least one resistor. The plug device is configured to arrange the at least one resistor to connect electrically two of the plug connectors. The control circuit performs a step of measuring voltages applied to each of the input terminals, and then proceeds with a step of selecting a predefined operation mode of the emergency luminaire based on the at least two measured voltages.

The memory 17 may store a look-up table or the like in which data is stored for different operational modes of the emergency luminaire associated with voltage values or ranges of voltage values for combinations of measured voltages at the input terminals 15 and 16.

A particular embodiment of the control unit 2 may include a look-up table in which instances for a time duration for an emergency illumination are stored and each stored time duration is stored associated with a combination of voltage values for analogue voltages at the input terminals 15, 16. Thus, the control circuit 2 may implement a duration select function using the mode selecting system acting as a duration selecting system.

The control circuit 2 is configured to measure voltages applied to each of the input terminals 15, 16 and to select an operation mode for the emergency luminaire based on the measured voltages.

The mode selecting device 1 further includes a jumper block 3. The jumper block 3 includes at least three socket connectors 8, 9, 10.

The mode selecting device 1 further comprises a connecting circuit 5 configured to electrically connect the socket connectors 8, 9, 10 with the input terminals 15, 16 of the control circuit 2.

The connecting circuit 5 depicted in fig. 1 represents one example for a resistive connecting circuit 5 including resistors Ri to R8. The depicted example uses resistors Ri to R8 with a resistor value of 1 kt2 each. The connecting circuit 5 provides a voltage reference of +15V DC via the jumper block 3 to the plug device 4 and provides the analogue voltages VADci and VADc.2 at the input terminals 15, 16 of the control circuit 2 in dependence from the electrical configuration of the plug device 4.

The depicted connecting circuits in fig. 1 is one particular example, other embodiments may show other circuit topologies and circuit element dimensions.

The plug device 4 of the mode selecting system is configured to connect mechanically with the jumper Nock 3. Fig. 3 shows an exemplary embodiment with its mechanical layout.

The jumper device 4 of fig. 1 includes an open connection 14 at the plug connector 15.

Fig. 2 provides an overview of an emergency luminaire 20 with a mode selecting system according to an embodiment of the invention. The emergency luminaire 20 is a 20 simplified example for an emergency lighting system.

In the emergency luminaire 21, an emergency converter 18, sometimes also referred as DC/DC converter, ballast or driver device, is employed for providing a supply current to an emergency light source 19 for a predetermined time in case mains supply fails. The supply current is maintained in case of a mains supply failure for a rated service time using energy stored in an energy storage device 20 such as a rechargeable battery. The rated service time defines a battery discharge duration during which time the emergency converter 18 is required to drive the emergency light source 20 with a predetermined drive current. This predetermined drive current is a minimum load current enabling the emergency light source fulfil its task of providing an emergency light level for the rated service time.

The rated service time or the minimum load current are usually selectable at the emergency converter 18 using a duration select switch. The duration select switch can, for example, set the rated service time to either 1, 2 or 3 hours. The duration select switch is one specific example of the plug device 4. Selecting the rated service time may then be an example for selecting an operation mode of the emergency converter 21.

The emergency lighting system may arrange the components of the emergency luminaire 21 distributed over an area, for example a building. However, the basic functions of the components emergency converter 18, emergency light source 19, and energy storage device 20 are independent if it is a compact emergency luminaire 21 with a mode selecting system or an emergency converter 18 with a mode selecting system and emergency light source 19 and energy storage device zo arranged spatially io separate.

Fig. 3 shows a table depicting the relation between electrical arrangement of the at least one resistor 7 and analogue input voltages VADei and VADc2 at the input terminals 15, 16 of the control circuit 2 according to an embodiment.

An entry in column 22 of fig. 3 includes an identifier ranging from 1 to 6 for the corresponding operation mode of the emergency luminaire. Each identifier in column 22 may denote a specific operation mode, a specific operation function, and or a specific parameter setting of the emergency luminaire.

The column 23 of the table provides for each operation mode a corresponding configuration of the plug device 4. Fig. 3 assumes the plug device 4 having three plug connectors 11, 12, 13. The plug device 4 for which the table of fig. 2 applies further includes three positions 7.1, 7.2, 7.3 for arranging one or two resistors 7.

Resistor position 7.1 arranges the resistor 7 electrically connected between the plug connector n and the plug connector 12. Alternatively or additionally, a resistor 7 may be arranged on resistor position 7.2 electrically connected between the plug connector 12 and the plug connector 13. Alternatively or additionally, a resistor 7 may be arranged on resistor position 7.3 electrically connected between the plug connector 11 and the plug connector 13.

The plug device 4 shown in fig. 3 enables six different operation modes due to comprising three plug connectors 11, 12, 13 corresponding to three socket connectors 8, 9, 10 and three resistor positions 7.1, 7.2, 7.3 for either one or two resistors 7.

Thus, an increased number of operation modes (six) is selectable by the mode selecting system, when compared with the conventionally known mode selecting system employing the same number (three) of socket connectors arranged externally accessible on a jumper block.

Depending on the actual configuration of the plug device 4, and the actual configuration of the connecting circuit 5 of the mode selecting device 1, corresponding values of analogue voltages VADct and VADC2 apply at the input terminals 15, 16 of the control circuit 2.

Column 24 displays the analogue input voltage VADC, at the input terminal 15 for each io of the operation mode identifiers ito 6 and their respective configuration of the plug device 4. Column 25 displays the analogue input voltage VADc2 at the input terminal 16 for each of the operation mode identifiers ito 6 and their respective configuration of the plug device 4.

The table of fig. 3 highlights the option with the operation mode identifier "2" with a marker 26, with the plug device 4 having a plug configuration (plug option) arranging the (single) resistor 7 on resistor position 7.1 between the plug connectors n and 12. When connecting the plug device 4 with the jumper block 3, the plug connector 12 may be provided via the socket connector 9 of the jumper block 3 and the connecting circuit 5 with a supply voltage of +15 \Inc. Thus, the voltage VADei with a voltage value of 2.9 V is input to the first terminal 15 of the control circuit 2. The voltage VADc2 with a voltage value of 10.2 V is input to the second terminal 16 of the control circuit 2, as the marker 26 in fig. 3 displays.

Based on the information shown in fig. 3, a look-up table may be devised. Using the measured voltage values (digital voltages) of the analogue voltages VAnci and V1nc2 as input values, the control circuit 2 may determine the corresponding operation mode for the emergency luminary 21. The look-up table may be stored in the memory 17.

The advantages of the increased number of selectable operation modes becomes apparent for the example of figs. 1 and 2 with a jumper block 3 with three socket connectors 11, 12, 13. Nevertheless, the number of socket connectors 8. 9, 10 may be increased, and in combination with an increased number of resistor positions 7.1, 7.2, 7.3, 7.4, the number of selectable operation modes for the emergency luminaire increases significantly at the expense of increased mechanical dimensions of the components of the mode selecting system.

The first plug connector 11 and the second plug connector 12 are two plug connectors of the three plug connectors 11, 12, 13 of the plug device 4 displayed in the bottom view of the plug device 4 according to fig. 3.

The plug device according to fig. 4 arranges no resistors 7 on resistor positions 7.2 and 7.3.

The plug connectors 11, 12, 13 may be formed by sleeves made from an electrically conducting material and inserted into corresponding openings of the body of the plug device 4. The plug connectors 11, 12, 13 may show extended portions on one end, the extended portion providing the capability to electrically connect the resistor 7 between the extended portions of the respective pair of plug connectors 11, 12, 13.
