Description

The present invention relates to an emergency light and an electrical module for such an emergency light.

Safety lights are used in buildings to provide basic lighting (e.g. of an escape route) so that people can safely exit a building in the event of an emergency such as fire and/or power failure. An exit light with an exit sign element that is illuminated by the exit light source is referred to as an exit sign light.

Safety Sign Luminaires are used in buildings to illuminate a safety sign such as an escape route sign. Consequently, the safety sign displayed by the safety sign lamp can also be seen by people in a dark area, such as a windowless room or hallway without lighting (e.g. lighting is defective or has failed). This is important because a safety sign should be visible to people in an area regardless of the state of the lighting in an area.

It is advantageous if, in addition to pure lighting, further functions can be integrated into a safety light without thereby impairing a basic function of the safety light, namely lighting (emergency lighting). This is also desirable in safety sign luminaires.

In the light of this prior art, it is therefore an object of the present invention to provide a safety light in which, in addition to a lighting function, at least one further function can be integrated without the lighting function of the safety light being impaired as a result.

These and other objects that may be mentioned or recognized by a person skilled in the art upon reading the following description are solved by the subject matter of the independent claims. The dependent claims develop the central idea of the present invention in a particularly advantageous manner.

According to one aspect of the present invention, a security light is provided. The safety light comprises a housing with a cavity sealed against environmental influences and at least one further cavity adjoining the cavity. the The safety light also includes an electrical energy supply for the safety light, which is arranged in the cavity of the housing. The safety light is set up in such a way that at least one electrical module can be arranged at least partially in the at least one further cavity via an opening of the at least one further cavity to the outside, and that the at least one electrical module can be supplied electrically from the electrical energy supply of the safety light, if the at least one electrical module is at least partially arranged in the at least one further cavity.

The present invention thus proposes providing a safety light in which the electrical energy supply of the safety light is arranged in a cavity of the housing of the safety light that is sealed against environmental influences, and at least one electrical module is at least partially arranged in at least one further cavity of the housing adjoining this sealed cavity can be arranged and, in the arranged state, can be electrically supplied from the electrical power supply.

The sealed cavity has the advantage that the electrical power supply of the safety light is protected against environmental influences, such as water, dust, gases and/or contact from the outside (e.g. vandalism), and consequently the lighting function of the safety light is protected against environmental influences , i.e. the lighting that can be provided by the safety light, is protected against environmental influences. The additional cavity of the housing has the advantage that at least one electrical module can be arranged (at least partially) in it, with the arrangement of such an electrical module enabling the function of the safety light to be expanded by the function of the electrical module. Due to the arrangement of the at least one electrical module in the at least one further cavity, the cavity protected against environmental influences is not used for such an arrangement and is consequently also not changed. Consequently, such an arrangement has no influence on the electrical power supply arranged in the sealed cavity of the housing and the illumination of the safety light dependent thereon. Therefore, according to one aspect of the invention, the safety light allows the function of the safety light to be expanded without the function of the lighting of the safety light being impaired as a result.

In other words, the cavity of the housing is protected against environmental influences. The environmental influences can include dust and water. Therefore, the cavity of the case can be a dust- and water-sealed cavity.

The cavity can be protected in particular according to the IP protection classes. The abbreviation can stand for "International Protection" or "Ingress Protection". These protection classes are specified in the standard "DIN EN 60529: Degrees of protection provided by housing". As a rule, an IP protection class comprises a two-digit combination of numbers that indicates the degree of protection. The first digit indicates the protection class for protection against foreign bodies and contact (e.g. dust protection). The second digit indicates the protection against water (e.g. splash water protection). The terms "IP protection class", "IP protection class" and "IP code" can be understood synonymously.

Optionally, the cavity is IP65 protected. I.e. the cavity can be an IP65 protected area of the housing.

"At least one other cavity" means "one more cavity or more more cavities". The following description regarding the at least one cavity applies to each additional cavity if the housing includes two or more additional cavities (besides the environmentally protected cavity).

The passage “at least one electrical module can be arranged at least partially in the at least one further cavity” is to be understood as meaning that the at least one electrical module can be arranged partially or completely in the at least one further cavity. If the electrical module is partially arranged in the at least one further cavity, at least one component of the electrical module can be arranged outside of the at least one further cavity, for example protruding from the at least one further cavity via the opening outside the housing.

Furthermore, according to an optional alternative, with a partial arrangement of the electrical module, the electrical module can be arranged on the opening of the at least one further cavity, wherein at least one component of the electrical module can be arranged within the at least one further cavity, for example via the Opening can protrude into the at least one further cavity of the housing. For example, the electrical module can be a plate which can be arranged on the opening of the at least one further cavity in such a way that at least one element connected to the plate or at least one component part of the plate is arranged in the at least one further cavity or protrudes into it if the plate is placed on the opening. The plate can preferably be arranged on the opening of the at least one further cavity in such a way that the opening is closed, optionally sealed, when the plate is arranged on the opening. The terms "plate" and "disc" can be used synonymously and denote an element that extends over a large area.

The at least one additional cavity, in particular the opening of the at least one additional cavity, can be set up in such a way that the opening of the at least one additional cavity is closed, optionally sealed, when the at least one electrical module is at least partially arranged in the at least one additional cavity . In other words, the at least one further cavity can be closed, optionally sealed, from the outside by an (at least partial) arrangement of the at least one electrical module in the at least one cavity. With regard to this seal, the above statements regarding the protection against environmental influences of the cavity of the housing that is sealed against environmental influences are correspondingly applicable.

The at least one further cavity, in particular the opening of the at least one further cavity, can be set up in such a way that a cover (e.g. blind cover) can be arranged on the opening of the at least one further cavity in order to close the opening. The cover may be a plate (cover plate).

The electrical energy supply can include at least one electrical energy store, for example a battery or an accumulator (accumulator), at least one power pack and/or at least one operating device for operating a light source of the safety light. The at least one electrical energy store can be rechargeable. The light source can include or correspond to one or more light-emitting diodes. The light source is arranged in the cavity of the housing and the cavity is arranged in such a way that the light source is arranged to emit light from inside the cavity to outside the cavity and consequently to the outside of the housing. The housing is at least partially made of light-transmitting material, optionally translucent material and/or transparent material, through which the light source arranged in the cavity of the housing can emit light to the outside of the housing. The surface of the housing over which the light source emits light can also be referred to as the light emission surface of the housing.

In particular, further electrical components can be provided in the cavity. For example, a control unit for controlling the light output of the safety light can be arranged in the cavity of the housing. In particular, the control unit can be set up to control the electrical energy supply, in particular the at least one optional operating device, and consequently the light source. The control unit can A processor, a microprocessor, a controller, a microcontroller, an application specific integrated circuit (ASIC), a FPGA ("Field Programmable Gate Array") or any combination of the above elements.

Optionally, the safety light can be attached to a surface, such as a wall or ceiling of a room, in the area of the at least one further cavity of the housing. For this purpose, at least part of at least one fastening element, which can be used to fasten the safety light to the surface, can be arranged within the at least one further cavity. The attachment can be force-fitting and/or form-fitting. For example, the safety light can be screwed to the surface by means of at least one screw arrangement comprising one or more screws, with the part of the screw arrangement that is visible in the fastened state (which does not disappear in the surface, e.g. wall or deck) being arranged in the at least one further cavity can be. The safety light can be attached to the surface at a distance from the surface by the at least one fastening element.

The safety light can comprise at least one fastening module, which is set up for fastening a safety sign element to the housing of the safety light in such a way that when the safety sign element is in the fastened state, a light source arranged in the cavity of the housing is set up to illuminate the safety sign element. The at least one fastening module is optionally set up for detachably fastening the security sign element on the housing in such a way that when the security sign element is in the fastened state, the light source arranged in the cavity is set up for illuminating the security sign element.

The fastening module can be set up for fastening the security sign element to the housing in such a way that when the security sign element is in the fastened state, light emitted by the light source arranged in the cavity is coupled into the security sign element. The security sign element can be a light guide plate into which light can be coupled. The light coupled into the light guide panel can illuminate at least one security indicia present on a surface of the panel. The terms "plate" and "disc" can be used synonymously and denote an element that extends over a large area. Consequently, a light guide plate can also be referred to as a "light guide disk".

The at least one fastening module can comprise at least one fastening element. The fastening module, in particular the at least one fastening element, can be set up to detachably fasten the safety sign element to the housing of the safety light. The fastening module, in particular the at least one fastening element, can be set up to be brought into engagement with the security sign element. The at least one fastening module, in particular the at least one fastening element, can be used to be connected to the security sign element in a non-positive and/or positive manner. The at least one fastening module, in particular the at least one fastening element, can be set up for a click connection, snap-in connection, sliding connection, screw connection, plug-in connection or any other known connection type for connection to the safety sign element in order to attach the safety sign element to the housing of the safety light.

For example, if the at least one fastening module is set up for a click connection for connection to the safety sign element, then the safety sign element can be clicked into the fastening module in order to be connected to the safety light or to be fastened to the safety light housing.

The at least one fastening module can be at least partially arranged in the first chamber of the two or more chambers. The at least one fastening module can be a plate which can be placed on an opening (to the outside) of the first chamber of the two or more chambers. Optionally, at least one element connected to the plate or at least one component part of the plate projects into or is arranged in the first chamber when the plate is arranged on the opening of the first chamber.

The opening of the at least one further cavity includes or corresponds in particular to an opening of the second chamber of the at least one further cavity. If the at least one further cavity comprises three or more chambers, the first chamber is provided for the at least one fastening module and the opening of the at least one cavity can comprise an opening of the second chamber and an opening of the third chamber. The at least one further cavity can be set up in such a way that an electrical module can be arranged at least partially in the second chamber and the third chamber via the respective opening, with the respective electrical module then being able to be supplied electrically starting from the electrical supply of the emergency light in the arranged state is. The at least one cavity preferably comprises three chambers arranged in a row. The first chamber, to which the at least one fastening module is assigned, can be arranged centrally and on both sides of the first chamber one chamber (second or third chamber) can be provided for a respective electrical module.

The two or more chambers can be arranged in a row. The at least one further cavity can, optionally essentially, correspond to the volume of a cuboid. The base area of the at least one further cavity can be rectangular. The opening of the at least one further cavity can, optionally, be essentially rectangular. The foregoing may apply to each compartment of the two or more compartments. A respective chamber can, optionally essentially, correspond to the volume of a cuboid. The opening of the respective chamber can optionally be essentially rectangular.

The at least one electrical module can, optionally essentially, be cuboid, i.e. have the shape of a cuboid.

The at least one fastening module can be cast at least partially in the at least one further cavity. The at least one fastening module can be an integral part of the housing. Alternatively, the at least one fastening module can be connected to the housing in a material, non-positive and/or positive manner.

The above description regarding at least one further cavity applies to each further cavity if the housing comprises two or more further cavities. The above description with regard to at least one fastening module applies to every fastening module if two or more fastening modules can be arranged in two or more further cavities.

If the safety light comprises two further cavities adjoining the first cavity, then at least one further cavity of the two further cavities can be set up or designed in such a way that at least one electrical module can be arranged at least partially in the further cavity via an opening in the further cavity. and the at least one electrical module can be supplied electrically from the electrical energy supply of the emergency light if the at least one electrical module is at least partially arranged in the further cavity. Alternatively, each additional cavity of the two additional cavities can be set up or configured in such a way that at least one electrical module can be arranged at least partially in the respective additional cavity via a corresponding opening in the respective additional cavity, and the at least one electrical module is based on the electrical energy supply the Safety lamp is electrically supplied when the at least one electrical module is at least partially arranged in the respective further cavity.

The safety light can include two fastening modules that are set up for the optionally detachable fastening of the safety sign element to the housing of the safety light in such a way that the light source of the safety light is set up for illuminating the safety sign element in the fastened state. Each of the two further cavities can comprise two or more chambers.

A fastening module of the two fastening modules can be arranged in each case in a first chamber of the two or more chambers. At least one electrical module can be arranged in a second chamber of the two or more chambers of at least one further cavity of the two further cavities. Alternatively, at least one electrical module can be arranged in the second chamber of the two or more chambers of each additional cavity of the two additional cavities.

The safety light can include the safety sign element, which is fastened to the housing via the at least one fastening module in such a way that the light source is set up to illuminate the safety sign element. Optionally, the security sign element is detachably attached to the housing via the at least one attachment module in such a way that the light source is set up to illuminate the security sign element.

The safety light can be referred to as an safety sign light when the safety light includes the safety sign element.

Optionally, the safety light includes at least one conductor loop that is electrically connected to the electrical power supply. The at least one conductor loop is arranged in the cavity in such a way that the at least one conductor loop can be inductively coupled to at least one conductor loop of the at least one electrical module when the at least one electrical module is at least partially arranged in the at least one additional cavity.

This allows an electrical supply of the at least one electrical module based on the electrical energy supply of the emergency light without affecting the ability of the cavity to protect against environmental influences, such as dust and water, if the at least one electrical module is at least partially arranged in the at least one additional cavity is.

The at least one conductor loop of the security sign element can be arranged in the cavity on a surface (inside) of the cavity in the cavity. The at least one conductor loop of the at least one electrical module can be arranged on a surface (inside or outside) of the at least one electrical module. The arrangement of the at least one conductor loop of the security sign element and/or the at least one conductor loop of the at least one electrical module can be planar.

As at least one conductor loop electrically connected to the electrical energy supply, the safety light can comprise a coil which is electrically connected to the electrical energy supply and can be inductively coupled to the at least one conductor loop of the at least one electrical module. The at least one electrical module can comprise a coil as at least one conductor loop, which coil can be inductively coupled to the at least one conductor loop of the emergency light.

The safety light optionally includes at least one electrical tap which is electrically connected to the electrical energy supply. The at least one electrical tap is arranged in the at least one additional cavity in such a way that the at least one electrical tap of the safety light makes electrical contact with an electrical tap of the at least one electrical module, and a seal of the at least one electrical module makes electrical contact with the at least one electrical tap of the safety light seals when the at least one electrical module is at least partially arranged in the at least one further cavity.

This allows an electrical supply of the at least one electrical module based on the electrical energy supply of the emergency light without affecting the ability of the cavity to protect against environmental influences, such as dust and water, if the at least one electrical module is at least partially arranged in the at least one additional cavity is. The seal ensures this. The seal of the at least one electrical module can be a sealing bead.

The at least one electrical module can be cast. In particular, the at least one electrical module cannot have its own electrical energy supply, such as a battery or an accumulator (accumulator) and/or a power pack. The at least one electrical module is supplied with electricity from the electrical energy supply arranged in the cavity of the housing of the safety light the safety light when the at least one electrical module is at least partially arranged in the at least one further cavity of the housing of the safety light.

Communication between elements of the safety light arranged in the cavity, such as a control unit of the safety light, with the electrical module, if this is at least partially arranged in the further cavity of the housing, can be wireless or wired as above with regard to the electrical supply. This means that one or more conductor loops (wireless communication) and/or one or more electrical taps (wired communication) can be used.

The at least one further cavity, in particular the second chamber of the optional two or more chambers, can comprise at least one fastening element. The at least one fastening element is set up to fasten the at least one electrical module to the housing when the at least one electrical module is at least partially arranged in the at least one additional cavity, in particular in the second chamber.

The at least one fastening element for fastening the at least one electrical module can be set up to fasten the electrical module to the housing of the emergency light in a detachable manner. The at least one fastening element can be configured to be brought into engagement with the electrical module. The at least one fastening element can be used to be connected to the electrical module in a non-positive and/or positive manner. The at least one fastening element can be set up for a click connection, snap-in connection, slide connection, screw connection, plug-in connection or any other known connection type for connection to the electrical module in order to fasten the electrical module to the housing

For example, if the at least one fastening element for fastening the at least one electrical module is set up for a click connection for connection to the electrical module, then the electrical module can be clicked into the at least one further cavity (in particular in the second chamber) in order to to be attached to the housing of the safety light.

If the at least one fastening element for fastening the at least one electrical module is set up for a sliding connection for connection to the electrical module, then the electrical module can be pushed at least partially into the at least one further cavity (in particular into the second chamber) in order to attach to the housing to be attached.

The at least one fastening element for fastening the at least one electrical module can be an integral part of the housing. Alternatively, the at least one fastening element can be connected to the housing in a material, non-positive and/or positive manner.

The at least one electrical module can be a loudspeaker module, a camera module, a sensor module, a communication module for wireless communication and/or a light-emitting diode module. The light-emitting diode module is optionally a light-emitting diode module with an optical system. The optics may include or correspond to a lens assembly, such as a Fresnel lens assembly. Optionally, the sensor module is a sensor module for detecting gases, temperature, light, movement of a person and/or presence of a person. In other words, the sensor module can be a sensor module for detecting gases, such as a carbon dioxide (CO ₂ ) sensor module for detecting carbon dioxide and/or a carbon monoxide (CO) sensor module for detecting carbon monoxide. Additionally or alternatively, the sensor module can be a smoke detector module for detecting smoke, a temperature sensor module for detecting a temperature (ambient temperature), a light sensor module for detecting light (e.g. ambient light), a motion sensor module for detecting a movement of a physical object (e.g. a person) and/or a Person detection sensor module for detecting the presence of a person.

The loudspeaker module allows information to be output to people in the vicinity. In particular, the integration of a loudspeaker module into the housing of the safety light, comprising a safety sign element, is advantageous for a so-called two-senses principle. This can be used to comply with guidelines (e.g. of the European Union) against discrimination against people with impaired vision. Because in addition to the visual display of a safety sign, e.g. in the form of a pictogram, by the safety sign element, the displayed safety sign can also be output acoustically by the loudspeaker module if this is at least partially arranged in the at least one other cavity of the safety light.

A communication module for wireless communication allows a communication function to be integrated into the safety light. The safety light can be set up such that the communication module can be wired or wirelessly connected or coupled to a control unit of the safety light arranged in the sealed cavity of the housing when the communication module is at least partially arranged in the at least one further cavity. As already explained above, for a wireless connection, at least one conductor loop, preferably a coil, electrically connected to the control unit, can be located within the Be arranged cavity of the housing, which is set up for inductive coupling with at least one conductor loop of the communication module. At least one electrical tap can be provided for a wired connection, which is electrically connected to the control unit arranged inside the cavity of the housing. This at least one electrical tap of the safety light is arranged in the at least one further cavity of the housing in such a way that the at least one electrical tap of the safety light is in electrical contact with an electrical tap of the communication module and a seal of the communication module seals the at least one electrical tap of the safety light, if the communication module is at least partially arranged in the at least one further cavity.

Communication between the control unit of the emergency light and the communication module can optionally take place by means of the elements for the electrical supply of the communication module based on the electrical energy supply of the emergency light if the communication module is at least partially arranged in the at least one further cavity. Consequently, when the communication module is at least partially arranged in the at least one further cavity, the control unit can be set up to communicate wirelessly with the outside (external elements outside the housing of the emergency light) via the communication module. Upgrading the safety light with the communication module allows wireless communication between such safety lights and/or a central communication unit.

The wireless communication can take place according to the Bluetooth standard, the W-LAN standard and any other known wireless communication method.

The communication module can additionally or alternatively be set up to communicate wirelessly independently of the emergency light, in particular the control unit, if the communication module is at least partially arranged in the at least one further cavity. In this case the communication module can function as a repeater of wireless communication when the communication module is at least partially arranged in the at least one further cavity.

A camera module and a sensor module each allow the safety light to obtain information about the environment, such as the presence of people in the environment, the presence of smoke in the environment and toxic gases (e.g. carbon dioxide - CO ₂ , carbon monoxide - CO, etc.), a Ambient temperature, ambient light, etc., and based on this information, environmental conditions, for example an emergency (eg detection of toxic gases), and/or to control the light output of the security light.

For this purpose, the safety light can be set up as described above (with regard to the communication module), so that the camera module or the sensor module is electrically connected to the control unit of the safety light when the camera module or the sensor module is at least partially arranged in the at least one further cavity. Consequently, detection results of the camera module or the sensor module can be made available to the control unit of the emergency light if the camera module or the sensor module is at least partially arranged in the at least one further cavity.

Sensor modules integrated in the safety light can be used in normal operation (mains operation) of the safety light for Internet of Things (IoT) applications. These include the following examples. For desk management, the safety light can be equipped with a presence sensor module (e.g. having one or more pyroelectric sensors (PIR sensors)) as an electrical module. A safety light equipped in this way allows you to identify which office desks or rooms (e.g. meeting rooms) are occupied or not at a given time. At least one electrical module can be used for indoor navigation, which is set up to determine the position of a person, e.g. via the wireless signal (e.g. radio signal) from a person's mobile end device (e.g. smartphone). The safety light can then guide the person to a desired position, e.g.

A safety light can be set up for dynamic escape route lighting by integrating at least one electrical module, such as a smoke detector or carbon dioxide sensor module. In an emergency, in particular in the event of a power failure, such a sensor module (electrical module) can be supplied with electricity via the electrical energy supply, in particular at least one electrical energy store, of the safety light if the sensor module is at least partially arranged in the at least one further cavity of the safety light. Therefore, such a sensor module can be used for a dynamic escape route system in an emergency.

For example, if the at least one electrical module includes a smoke detector and/or a carbon dioxide sensor, then the electrical module is set up to detect smoke and/or fire. Consequently, the safety light, when equipped with such an electrical module, can be set up to determine a fire location and direct people away from the fire location by means of dynamic escape route signage. This is particularly applicable to a system comprising a plurality of such safety lights.

If the at least one electrical module comprises a presence sensor, for example a PIR sensor, and/or a camera, then the electrical module is for person detection (for example determining whether people are still in a burning building) and determining a condition of people (e.g. a person lying unconscious on the ground). Consequently, the safety light, when equipped with such an electrical module, can be set up to determine such data, e.g. whether there are still people in the vicinity of the safety light and optionally the condition of the people (e.g. unconscious or not). This data can then be transmitted wirelessly, e.g. to the fire brigade at the scene. For this purpose, the emergency light can be equipped with an additional electrical module in the form of a communication module for wireless communication.

As already stated above, the safety light can be equipped with simple actuators by integrating at least one electrical module in the safety light (at least partially in the at least one further cavity of the housing).

For example, the electrical module can be a speaker module. In normal operation, in particular mains operation, the loudspeaker module can be set up as a simple loudspeaker system (e.g. for speeches in an auditorium) and in emergency operation for safety announcements (e.g. an acoustic request to leave the building) and/or for acoustic escape route guidance if the loudspeaker module is at least is partially arranged in the at least one other cavity of the safety light.

The electrical module can be a light-emitting diode module (e.g. an LED module or OLED module) that can be switched on when required.

In mains operation, for example, the light-emitting diode module can be set up to illuminate a desired/searched product in the vicinity of the safety light in response to a corresponding search query on a mobile device (e.g. an app on a smartphone) if the light-emitting diode module is at least partially in the at least another cavity of the safety light is arranged. For this purpose, the security light can be equipped with a further electrical module in the form of a communication module for wireless communication with the mobile terminal device.

Furthermore, a light-emitting diode module can be set up to indicate that the safety light on which the light-emitting diode module is provided needs to be repaired, in particular in response to a corresponding search query on a mobile device (e.g. a maintenance app on a smartphone).

For example, in emergency operation (emergency lighting), a light-emitting diode module comprising at least one laser light-emitting diode can be set up to project information (e.g. arrows) onto the floor in the lighting area of the safety light when the light-emitting diode module is at least partially arranged in the at least one other cavity of the safety light is. This allows the direction of the escape route to be displayed directly on the escape route.

If the safety light is a safety sign light and consequently the light source arranged in the cavity of the housing is provided for illuminating the safety sign element, then at least one light-emitting diode module for illuminating the area surrounding the safety sign light can be arranged at least partially in the at least one further cavity. For this purpose, the safety light can be set up as described above (with regard to the communication module), so that the light-emitting diode module is electrically connected to the control unit of the safety light (arranged in the cavity of the housing) when the light-emitting diode module is at least partially arranged in the at least one further cavity. This allows the light-emitting diode module to be controlled by the control unit of the safety light when the light-emitting diode module is at least partially arranged in the at least one further cavity. The control unit of the safety light can be set up to control the light-emitting diode module, in particular its light output, when the light-emitting diode module is at least partially arranged in the at least one further cavity.

• in einem Normalbetrieb nur die Lichtquelle der Sicherheitszeichenleuchte zur Beleuchtung des Sicherheitszeichenelements eingeschaltet ist, und
• in einem Notfallbetrieb die Lichtquelle der Sicherheitszeichenleuchte zur Beleuchtung des Sicherheitszeichenelements und das Leuchtdiodenmodul zur Beleuchtung der Umgebung der Sicherheitszeichenleuchte eingeschaltet sind.

The light-emitting diode module can include at least one light-emitting diode, ie one or more light-emitting diodes. The control unit of the emergency light can be set up to control the light source arranged within the cavity of the housing and the light-emitting diode module, if this is at least partially arranged in the at least one further cavity, in such a way that

• in normal operation only the light source of the safety sign luminaire is switched on to illuminate the safety sign element, and
• in an emergency mode, the light source of the safety sign luminaire for illuminating the safety sign element and the light-emitting diode module for illuminating the surroundings of the safety sign luminaire are switched on.

The control unit can be set up to control the light source of the safety sign light in such a way that in emergency operation the light source emits dimmed light compared to the light output in normal operation.

The light-emitting diode module optionally includes a Fresnel lens arrangement for the at least one light-emitting diode of the light-emitting diode module. The Fresnel lens arrangement can be arranged on a light-emitting surface of the light-emitting diode module or be part of the light-emitting surface, the at least one light-emitting diode of the light-emitting diode module being set up to emit light outside of the light-emitting diode module via the Fresnel lens arrangement.

• das Leuchtdiodenmodul dazu eingerichtet ist, in einer zweiten Position der wenigstens zwei Positionen das Licht in einer Richtung parallel zu der Lichtabgabefläche des Gehäuses der Sicherheitsleuchte abzugeben.

If the at least one electrical module is a light-emitting diode module, then the safety light is optionally set up in such a way that the light-emitting diode module can be arranged in at least two positions at least partially in the at least one further cavity such that
