Description

[0001] Various examples concern a light-emitting cover for a functional use in a flush-mounted box.

[0002] Conventional night lights are plugged into an existing socket and thus block the plug socket of the socket.

[0003] Night lights with plug-in sockets are also common. However, these night lights can be easily removed.

[0004] Night lights and stair lights are also known that can be installed in flush-mounted boxes. The flush-mounted box is blocked for the lighting function.

[0005] Light switches for flush-mounted boxes with a light integrated into the user interface are also known. The light is intended to make it easier to locate the control element in the dark. However, the design of the light on the user interface does not allow for any illumination of the surrounding area.

[0006] Examples are known from DE 10 2010 008 507 A1, US 6 350 039 B1, DE 20 2017 107 792 U1, DE 10 2009 019 264 A1, DE 100 26 256 A1, EP 1 041 693 A1 and DE 10 2007 008 626 A1.

[0008] In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific examples in which the invention may be practiced. In this regard, directional terminology such as "top", "bottom", "front", "back", "fore", "rear", etc., will be used with reference to the orientation of the described figure(s).

It is to be understood that other examples may be utilized and structural or logical changes may be made without departing from the scope of the present invention. It is to be understood that the features of the various example embodiments described herein may be combined with one another unless specifically stated otherwise.The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0009] Throughout this description, the terms "connected," "attached," and "coupled" are used to describe both a direct and an indirect connection, a direct or indirect connection, and a direct or indirect coupling. In the figures, identical or similar elements are provided with identical reference numerals where appropriate.

[0010] Fig. 1A is a schematic cross-sectional view of a switch 100 with a flush-mounted box 122 in a wall 102, Fig. Figure 1B is a schematic plan view of Fig. 1A, and Fig. 1C is a power flow diagram of the switch 100 of Fig. 1A and Fig. 1B.

[0011] The switch 100 may include a user interface 104 (also referred to as a user interface), a light-emitting panel 170, and an insert 130 (also referred to as a switch insert in the switch) for a flush-mounted box 122.

[0012] The flush-mounted box 122 has a housing 120 which is mounted in a wall 102. The flush-mounted box 122 has a plurality of screw domes (see Fig. 3), for example four screw domes to which the insert 130 is conventionally fastened, for example by means of a screw connection and / or by means of a clamp connection (not illustrated).

[0013] The insert 130 can be any conventional switch insert, for example, for a push button, a rocker switch, a double switch, a rotary switch, a push button switch, or the like. The insert 130 (also referred to as a functional insert or electrical insert) has the electromechanical components of the switch to interrupt (also referred to as an off state) or close (also referred to as an on state) the electrical circuit between a power supply 150 and a load 140.

[0014] Conventionally, a control surface 104 is applied to the insert and a cover is arranged between the control surface 104 and the wall 102 to conceal the flush-mounted box 122 and the screw connections of the insert 130.

[0015] In a conventional circuit (see Fig. 1C upper section), the insert 130 is electrically coupled between a load 140, for example, a lamp 140 emitting light 142, and a power grid 150 or a power grid connection 150 (for example, a power cable). The insert 130 can control the power supply to the load 140 by means of different switching states, for example, providing or interrupting power 128 to the load 140 (also referred to as passing or interrupting power, or turning on and off). The switching states of the insert 130 can be selected by a user via the user interface 104. As shown in Fig. 1A and Fig. As illustrated in Figure 1C, a current 122, 124 is provided from the power supply 150 to an input of the insert 130. An output of the insert 130 passes the current 128 to the load 140 in the switching state of a closed circuit. In the case of a lamp 140 as the load 140, this lamp can emit light 142 (also referred to as primary illumination), for example.

[0016] The light-emitting aperture 170 may include an aperture housing 110, a light-emitting component 114, a controller 160, and a driver circuit 500 for the light-emitting component 114.

[0017] Depending on the application, for example, with a function as an emergency light, the light-emitting panel 170 can have an energy storage device 162. Using the energy storage device 162, the light-emitting component 114 can emit light 112 even when no power 126 is supplied by the power grid 150—this function is referred to as emergency lighting.

[0018] The control device 160 of the light-emitting aperture 170 is coupled to the power supply connection 150 in front of or on the insert 130, as shown in Fig. 1C. For example, a power connection of the light-emitting aperture 170 may be coupled to the power cable of the power connector 150 and a power connection to the insert 130 at a terminal, such as a wire terminal or Wago terminal (also referred to as a common node). Alternatively, the power connection (i.e., the power input) of the light-emitting aperture 170 may be coupled to a power input of the insert 130, such as at or in a power input of the insert 130. The light-emitting aperture 170 is, for example, electrically connected in parallel to the insert 130. Regardless of the type of coupling, a portion 126 of the power 122 provided by the power grid 150 is supplied to the control device 160 of the light-emitting aperture 170, and another portion 124 is supplied to the insert 130.

[0019] The control device 160 may supply the input current 126 as a second current 168 to a driver circuit 500, as shown in Fig. 5. Alternatively or additionally, the control device 160 can supply a portion of the input current 126 as a charging current 164 to an energy storage device 162 of the light-emitting panel 170. The energy storage device 162 can supply a first current 166 to the driver circuit 500 in emergency lighting mode for operating the light-emitting component 114, as shown in Fig. 5 is described in more detail.

[0020] Depending on the application, the light-emitting aperture 170 can emit light 112 independently of the operating state of the lamp 140 (as load 140). For example, the light-emitting component can emit light 112 when the lamp 140 is off, for example, the switch insert 130 is switched to "open," or the lamp 140 is defective. The function of the light-emitting aperture 170 to emit light 112 independently of the lamp 140 is referred to as nightlight or secondary lighting.

[0021] Depending on the application, the light-emitting component 114 may, for example, be switched off when the lamp 140 emits light 142, the ambient light intensity is higher than a predetermined threshold, and / or the light-emitting component 114 is switched off by a user. The light-emitting aperture may have one or more switching components for this purpose (see also Fig. 11 and Fig. 12).

[0022] The light 112 of the light-emitting component 114 can be emitted in different spatial directions 112-1, 112-2, 112-3, 112-4, 112-5, 112-6, 112-7 depending on the application, for example through the aperture housing 110 (also referred to as direct light) or past it (also referred to as indirect light, see for example Fig. 7 and Fig. 8), directed away from the wall 102 and / or illuminating the wall 102.

[0023] The aperture housing 110 can, for example, serve or be configured as a diffuser or scattering body for the light 122 of the light-emitting component 114. When the light-emitting component 114 is switched off, the aperture housing 110 can be opaque, for example, opaque. Alternatively, the aperture housing can be opaque to direct light.

[0024] The aperture housing 110 may be configured to house the components of the light-emitting aperture 170.

[0025] In the event that the light-emitting aperture 170 includes a switching component for deactivating the light-emitting component 114, the control device 160 may include a bypass circuit that bypasses this switching component in the event that the mains power connection 150 is de-energized (also referred to as forced emergency lighting). The bypass circuit may, for example, include a normally-on transistor circuit, wherein the mains voltage controls the control connection and, in the event of a mains voltage being applied, blocks the transistor channel of the emergency lighting function.

[0026] As from Fig. 1A to Fig. 1C, the light-emitting aperture 170 can emit light 112 without impairing the functionality of the control, for example the operation of the user interface 104, of the conventional lamp 140.

[0027] The light-emitting component 114 can, for example, comprise one or more inorganic light-emitting diodes and / or one or more organic light-emitting diodes. The light-emitting components 114 can have a lower energy consumption than the lamp 140 controlled by the switch 100. This makes it possible to dispense with the primary lighting depending on the application, for example, when used as a night light and / or in combination with a motion detector, since the secondary lighting provided by the light-emitting panel 170 is sufficient. This enables energy savings.

[0028] Fig. 1A to Fig. 1C illustrates the connection of a light-emitting aperture 170 to the power connection of a switch 100. It is understood that the light-emitting aperture 170 can be designed as a common aperture for several switches arranged one below the other or next to each other (see also Fig. 14A, Fig. 14B). In this case, the input current 126 of the light-emitting panel 170 can be provided by a switch 100 of the plurality of switches. It is understood that, in the case of multiple flush-mounted boxes arranged side by side or one below the other with a common light-emitting panel 170, different switches and / or switches and sockets or other boxes, for example, network sockets or antenna sockets, can be combined. This allows the lighting to be extended to boxes that do not have their own power supply, for example, antenna sockets.

[0029] The user interface 104 can have a clamp connection with the insert 130. The panel housing 110 can extend partially under the user interface 104. The light-emitting panel 170 can thus be positioned on the wall 102 in a form-fitting and / or force-fitting manner. Alternatively or additionally, the light-emitting panel 170 can be fixed to the flush-mounted box and / or the wall (see also Fig. 3). The integration of the light-emitting panel 170 into the switch 100 enables improved theft protection compared to a night light that is simply plugged into a power outlet. Furthermore, the light-emitting panel 170 can provide improved ambient illumination by combining direct and indirect lighting.

[0030] The light-emitting aperture 170 may further comprise a communication module for wireless communication, for example, a Bluetooth, Bluetooth Low Energy, or WiFi terminal; or a communication module for communication through the power grid. The communication module may comprise a communication connection (in Fig. 1C by means of the dash-dot arrow 180) with a smartphone or a lamp control, for example, be smart home-capable. This allows, for example, the light color or the emission time (for example, during a color change) of the light 112 emitted by the light-emitting aperture 170 to be adjusted or to be coordinated or synchronized with another light source, for example, another light-emitting aperture or a lamp. The communication module can be integrated into the control device 160 or coupled to it.

[0031] Analogous to the switch 100, which in Fig. 1A to Fig. 1C, the light-emitting aperture 170 can be combined with other inserts 130 for a flush-mounted box 122, for example with a socket 200 as in Fig. 2A to Fig. 2D is illustrated.

[0032] The socket 200 has one or more plug sockets 204, for example for one or more protective contact plugs (SchuKo plugs) and / or one or more universal serial bus (USB) plugs.

[0033] As in Fig. 2B, the light-emitting cover 170 can have a plug socket 204. In this case, the light-emitting cover 170 can be connected to the insert 130 (here also referred to as a plug insert) like a conventional socket cover, for example by means of a screw connection. An analogous principle of a light-emitting cover 110 as a user interface 104 is also used in the switch 100 of the Fig. 1 applicable (see also for example Fig. 9A to Fig. 10B).

[0034] Alternatively, as in Fig. 2C, the socket 200 may include a conventional plug-and-socket cover 206 including the plug-and-socket 204. Here, the plug-and-socket cover 206 is conventionally secured to the insert 130 by means of a screw connection. In this case, the above-described light-emitting cover 170, which is also used for the switch 100 of Fig. 1A to Fig. 1C can be used, for the socket 200 can be used.

[0035] The cover housing 110 can extend partially under the plug-socket cover 206, for example, be arranged between the wall 102 and the plug-socket cover 206. The plug-socket cover 206 is conventionally screwed to the insert 130. The light-emitting cover 170 can thus be positioned on the wall 102 in a form-fitting and / or force-fitting manner.

[0036] The Fig. 2B may have a larger light-emitting area than the example shown in Fig. 2C. The connector base 204 and optionally an area around the connector base 204 may be free of the light-emitting component 114.

[0037] The screw connection of the plug socket 204 to the switch insert 130 and thus to the light-emitting cover 170 improves theft protection compared to a conventional night light or emergency light that is simply plugged into the socket. Furthermore, the functionality, such as the plug socket, remains intact for use.

[0038] As described above, the light-emitting panel can be arranged or fixed to the wall 102 by means of a positive connection and / or a clamp connection (see Fig. 1A and Fig. 2C). Furthermore, the light-emitting aperture 170 can be fixed to the insert 130 by means of a screw connection (see Fig. 2B).

[0039] Fig. 3A and Fig. 3B show schematic representations of an insert 130 of a flush-mounted box 122 with a light-emitting cover 170 for a general flush-mounted assembly 300, for example, the switch 100 or the socket 200. The light-emitting cover 170 can be configured according to a previously described example. The insert 130 can be any functional insert for a flush-mounted box, for example, the previously described switch insert or the previously described plug insert. However, the insert 130 can also be another insert, for example, for a network socket, for an antenna socket, for a stair light, or the like.

[0040] The housing 120 of the flush-mounted box 122 conventionally has a plurality of screw bosses 302-1, 302-2, to which the insert 130 can be secured by means of a screw connection and / or clamp connection. Conventionally, a flush-mounted box, for example, has four screw bosses, and a switch insert is secured to two of the four screw bosses opposite one another. The other two screw bosses remain unused or unoccupied.

[0041] Alternatively, the light-emitting aperture 170 can be attached, for example, to two screw domes 302-1, 302-2 of the flush-mounted box 122 by means of screws 304-1, 304-2 or screw connections, as shown in Fig. 3A. The light-emitting cover 170 can have through-openings at corresponding positions to accommodate or pass through screws 304-1, 304-2 corresponding to the screw bosses 302-1, 302-2 of the flush-mounted box 122. This allows the light-emitting cover 170 to be connected to the flush-mounted box 122 by means of a screw connection and / or a clamp connection. The light-emitting cover 170 can be arranged between the insert 130 and the flush-mounted box 122. The light-emitting cover 170 can be screwed to screw bosses 302-1, 302-2 of the flush-mounted box 122.

[0042] The light-emitting aperture 170 may further comprise one or more screw domes 306-1, 306-2 (see Fig. 3A) or through holes to the unused screw domes 302-3, 302-4 of the flush-mounted box 122 (see Fig. 3B). The insert 130 can be attached to the screw bosses of the light-emitting cover 170 and / or can be attached to the unoccupied screw bosses of the flush-mounted box 112 through the through-opening(s) of the light-emitting cover 170.

[0043] For example, the light-emitting cover 170 can be fixed to the wall 102 or the flush-mounted box 122 by means of a clamp connection, for example by connecting the insert 130 through one or more through-opening(s) 310-1, 310-2 of the light-emitting cover 170 to screw domes 302-3, 302-4 of the flush-mounted box 122 (see Fig. 3B). The screws 312-1, 312-2 for fixing the insert 130 in the unused screw bosses of the flush-mounted box 122 can be longer than conventionally used screws for attaching an insert to a flush-mounted box.

[0044] Alternatively, in case the light-emitting cover 170 is screwed to the flush-mounted box 122 (see Fig. 3A), the light-emitting cover 170 can have screw bosses 306-1, 306-2. The screw bosses 306-1, 306-2 of the light-emitting cover can be arranged at the positions of the unoccupied screw bosses of the flush-mounted box 122. This allows conventional inserts 130 to continue to be used. The screws 308-1, 308-2 for fixing the insert 130 to the light-emitting cover 170 can be shorter than conventionally used screws for fastening an insert 130 to screw bosses of a flush-mounted box.

[0045] Alternatively or additionally, the light-emitting panel 170 can be screwed to the wall 102 (not illustrated).

[0046] The light-emitting cover can be designed in the shape of a frame, for example having a through-opening, so that the insert 130 can be arranged at least partially in the flush-mounted box 122.

[0047] Screwing the light-emitting cover 170 to the flush-mounted box 122 can improve theft protection. Furthermore, the light-emitting cover 170 can be combined with conventional control surfaces, plug-and-socket covers, or similar covers - in Fig. 3A and Fig. 3B by means of the dash-dot line 330 and is referred to below as conventional aperture 330.

[0048] The conventional aperture 330 is arranged conventionally on the insert 130. In the Fig. 3A or Fig. 3B, a conventional cover 330 can be clearly arranged on the light-emitting cover 170 instead of conventionally on the wall 102. The light-emitting cover 170 can have a form-fitting receiving structure, for example a recess, to prevent the conventional cover 330 from slipping on the light-emitting cover 170. This allows conventional or already existing covers 330 to continue to be used. This allows greater design freedom when using covers, for example, a uniform appearance of the covers used on switches and sockets. Alternatively or additionally, the utility function of already existing sockets and switches can be improved. Thus, the design possibilities of conventional covers can be retained and conventional covers 330 can be functionally supplemented.

[0049] Fig. 4 illustrates a schematic top view of a control module 400 of an exemplary light-emitting aperture. The light-emitting aperture may be configured according to one of the described examples.

[0050] The control module 400 may include the control device 160 and the driver circuit 500 on a circuit board 402. The control device 160 may include one or more microcontrollers. The energy storage device 162 may be arranged on the same circuit board 402 as the control device 160 (see also Fig. 6A) or on another circuit board or another circuit board segment (see also Fig. 6B).

[0051] The control device 160 may also include a communication module (not illustrated) to enable a communication connection 180 with a communication device external to the aperture, for example, to adjust the emission time, the light color, or the light intensity of the light to be emitted by the light-emitting aperture.

[0052] In the example that an energy storage device 162 is provided, the battery management system of the control device 160 can be formed from a transistor circuit having one or more normally-on transistors and / or normally-off transistors, wherein the control signal for the control terminal of the transistors is based on a detected mains voltage of the power grid, which is supplied to a current input 450 of the control module 400.

[0053] The operating current 530 can be provided at a current output 460 of the control module 400 for the light-emitting component.

[0054] Fig. 5 illustrates in a schematic view an example of the driver circuit 500 of an exemplary light-emitting aperture.

[0055] The driver circuit 500 may include a current output 512 configured to provide an operating current 530 for operating the light-emitting component of the light-emitting aperture.

[0056] The driver circuit 500 may include at least a first current input 506 and a second current input 508 coupled to the current output 512.

[0057] The first current input 506 can receive a first electrical current 166 from a first energy source, for example, the energy storage device. In this case, the first current 166 can correspond to the current from the energy storage device.

[0058] The energy storage device can comprise one or more electrical energy storage devices, for example one or more capacitors and / or accumulators, for example metal-ion accumulators.

[0059] The second power input 508 may receive a second electrical current 168 from a second energy source, for example, a mains current 168.

[0060] The second current 166 is not necessarily identical to the mains current 126 from the power grid. For example, the control device can supply part of the electrical energy of the mains current to the energy storage device in order to charge it (see also Fig. 4).

[0061] The driver circuit 500 may include a mixer 524 coupled to the first current input 506, the second current input 508, and the current output 512. The mixer 524 may be configured to generate the operating current 530 from the first current and / or the second current and supply it to the current output 512.

[0062] The first current 166 and the second current 168 can have different current intensities, voltages, current densities, impedances, and / or frequencies. For example, the first current 166 provided by the energy storage device can be a direct current, and the mains current supplied to the second current input 508 can be an alternating current. Alternatively, however, the first current 166 and the second current 168 can each be a direct current or an alternating current.

[0063] The driver circuit 500 can have a first processing stage 520 and a second processing stage 522. The first processing stage 520 and the second processing stage 522 can be configured to process the first current 166 and the second current 168 in their capacity to approach the operating current 530, for example, by amplifying, attenuating, phase-delaying, rectifying, or passing, as examples. The first processing stage 520 can, for example, be configured to amplify the first current 166, for example, using a boost converter, or to pass it through. The second processing stage 522 can, for example, be configured to attenuate the second current 166, for example, using a buck converter, or to rectify it. The first processing stage 520 and the second processing stage 522 can be configured to process a respective input current differently.

[0064] Mixer 524 receives at least one current 166, 168 from one of the first processing stage 520 and the second processing stage 522 to generate the operating current 530 for the light-emitting component of the light-emitting aperture. If only one current is received, mixer 524 can output the received current as the operating current. Mixer 524 can be configured analogously to a conventional electrical mixer.

[0065] The first processing stage 520 can be configured, for example, as an electrical line or an electrical resistor to provide a current from the energy storage device to the current output 512 as operating current 530.

[0066] The second processing stage 522 may, for example, be configured as a rectifier circuit and / or an electrical resistor to provide a current from the power grid 168 to the current output 512 as operating current 530.

[0067] The control unit 518 can be configured to determine at least one property of the first current 166 and the second current 510, for example, a voltage or a current intensity. The control unit 518 can be configured to supply the first current 166 and the second current 168 to the first processing stage 520 or the second processing stage 522 depending on the determined property. For example, the control unit 518 can block the first current 166 from the energy storage device or prevent it from passing through if the control unit 518 determines a voltage at the second current input 508 or determines a mains current 168. The control unit 518 can, for example, have a normally-on transistor circuit, wherein the voltage of the second current input 508 at a control terminal of the transistor circuit controls the conductivity of the transistor channel.Alternatively, the control unit 518 can comprise a normally-off transistor circuit, with an inverted voltage of the second current input 508 being applied to a control terminal of the transistor circuit. However, the control unit 518 can also be configured as a microprocessor.

[0068] Fig. 6A and Fig. 6B illustrate schematic top views of exemplary light-emitting apertures 170. The light-emitting aperture 170 may comprise one or more frame-shaped printed circuit boards 402 stacked one above the other. The previously described electrical components of the light-emitting aperture 170, for example, the control device, the communication module, the driver circuit, the energy storage device, the light-emitting component (hereinafter also referred to as electrical modules) may be arranged on one or more sides of the frame-shaped printed circuit board(s) 402 and / or in different levels of the printed circuit board stack - in Fig. 6A and Fig. 6B as different modules 604-1, 604-2, 604-3, 604-4. The functional insert is arranged in the center of the frame-shaped circuit board 402, and a user interface of a switch or a plug socket of a power outlet, a network socket, or an antenna socket is arranged depending on the application.

[0069] For example, the energy storage device can functionally extend over two or more sides of the frame-shaped circuit board 402 and / or two or more levels of the circuit board stack. Depending on the application, the light-emitting component can be arranged, for example, on the topmost circuit board 402 of the circuit board stack and / or on the outer edge of the frame-shaped circuit board 402 on one, several, or all sides of the frame-shaped circuit board 402. The cover housing 110 can, for example, comprise an optical fiber or be configured such that light is guided from one side of the circuit board(s) to at least one other side.

[0070] The circuit board 402 may, for example, be a flexible printed circuit board or a stamped circuit board. Alternatively, the circuit board 402 may be a support structure (see also Fig. 9A to Fig. 10B). Electrical modules on the support structure can be coupled to one another by means of electrical connections 606, for example plug connections, wire connections and / or printed wires.

[0071] One or more sides of the frame-shaped circuit board 402 may be free of electrical modules of the light-emitting aperture. Depending on the application, individual electrical modules may be arranged on only one side of the frame-shaped circuit board 402.

[0072] As an alternative to the frame-shaped circuit board 402, a plurality of circuit boards 402-1, 402-2, 402-3, 402-4 (also referred to as circuit board segments) can be arranged in a frame. The circuit board segments can be electrically connected to one another or configured to be connectable, for example, by means of a plug connection. For example, the control device can be arranged on a circuit board segment, for example, to enable a modular construction of the light-emitting aperture and / or interconnection of a plurality of light-emitting aperture segments to form a common light-emitting aperture, for example, with a single control device (see also Fig. 13A to Fig. 14B).

[0073] Fig. 7 illustrates a schematic cross-sectional view of an exemplary light-emitting aperture 170. Here, the aperture housing 110 can be spaced apart from the wall 102 in the region of the light-emitting component 114, leaving the latter exposed. The aperture housing 110 can, for example, be opaque. The light-emitting component 114 can thus emit light 712 laterally to the aperture housing 110 (side looker). In this arrangement, the light-emitting component 114 can, for example, enable indirect lighting. This arrangement can be used, for example, in sockets for 90° protective contact plugs (SchuKo plugs), so that the 90° plug or the plug cable is not impaired by the light-emitting aperture. Alternatively or additionally, light 112 can be emitted through the aperture housing 110.Different lighting scenarios can be realized by combining indirect light 712 and direct light 112 through the aperture housing 110. For example, the direct light 112 and the indirect light 712 can have different colors.

[0074] Fig. Figure 8 illustrates a schematic cross-sectional view of an exemplary light-emitting aperture 170 analogous to that shown in Fig. 7. Here, the panel housing 110 can be spaced coplanarly from the wall 102, and the light-emitting component 114 can be exposed circumferentially. The light-emitting component 114 can thus emit light 712 laterally relative to the panel housing 110. This arrangement can be used, for example, in switches for indirect lighting. Alternatively or additionally, light 112 can be emitted through the panel housing 110. Different lighting scenarios can be realized from the combination of indirect light 712 and direct light 112 through the panel housing 110. For example, the direct light 112 (also referred to as direct lighting) and the indirect light 712 (also referred to as indirect lighting) can have different colors.

[0075] Fig. 9A and Fig. 9B illustrate a schematic cross-sectional view of an exemplary light-emitting aperture 170 in which the aperture housing 110 is a control surface of a switching component of the light-emitting aperture 170 and / or a switch.

[0076] The diaphragm housing 110 can be movably mounted on a support structure 904 (in Fig. 9 by means of arrow 902). The switching component can be, for example, a push button (push-push button). Alternatively, the panel housing 110 can be mounted so as to be freely movable.

[0077] The aperture housing 110 can, for example, be moved from a first position ( Fig. 9A) into a second position ( Fig. 9B) can be moved.

[0078] The light-emitting aperture 170 may have a first emission mode in the first position, for example, be in an off state or emit light 112 through the aperture housing 110.

[0079] The light-emitting aperture 170 may have a second emission mode in the second position, for example, be in an on state, emit indirect light 712 and / or emit direct light 112 through the aperture housing 110.

[0080] Movement 902 can increase the distance 906 between the panel housing 110 and the wall 102. Clearly, movement 902 can expose the light-emitting component 114 and thus activate indirect lighting. This arrangement can be used, for example, in switches for indirect lighting.

[0081] Alternatively or additionally, light 112 can be emitted through the aperture housing 110. Different lighting scenarios can be realized by combining indirect light 712 and direct light 112 through the aperture housing 110. For example, the direct light 112 and the indirect light 712 can have different colors.

[0082] In the case of an opaque bezel housing, the movement 902 may enable mechanical activation of the light-emitting component without visible operator interfaces.

[0083] Alternatively or additionally, if the aperture housing 110 is mounted freely (within the movement space), the light intensity of the indirect light 712 can be easily adjusted mechanically by means of the distance 906.

[0084] Fig. 10A and Fig. 10B illustrate a schematic cross-sectional view of an exemplary light-emitting aperture 170 in which the aperture housing 110 is a control surface of a switching component of the light-emitting aperture and / or a switch.

[0085] The aperture housing 110 can be mounted on a support structure 904 so as to be rotatable about a bearing 1002 (in Fig. 10 by means of arrow 1006). The switching component can be, for example, a push button (push-push button). Alternatively, the panel housing 110 can be mounted so as to be freely movable.

[0086] The aperture housing 110 can, for example, be moved from a first position ( Fig. 10A) into a second position ( Fig. 10B) can be moved, for example rotated.

[0087] The light-emitting aperture 170 may have a first emission mode in the first position, for example, be in an off state or emit light 112 through the aperture housing 110.

[0088] The light-emitting aperture 170 may have a second emission mode in the second position, for example, be in an on state, emit indirect light 712 and / or emit direct light 112 through the aperture housing 110.

[0089] The light-emitting component 114 can be exposed laterally by the rotating movement ( Fig. 10B) and thus activate indirect lighting. For example, the light-emitting component can be attached to the support structure 902.

[0090] Alternatively or additionally, the rotary movement 1006 can change a radiation direction of the direct light, for example through a lens effect of the diaphragm housing 110. This arrangement can be used, for example, in switches for indirect lighting.

[0091] Alternatively or additionally, light 112 can be emitted through the aperture housing 110. Different lighting scenarios can be realized by combining indirect light 712 and direct light 112 through the aperture housing 110. For example, the direct light 112 and the indirect light 712 can have different colors.

[0092] In the case of an opaque bezel housing, the movement 1006 can enable mechanical activation without visible operating surfaces.

[0093] Alternatively or additionally, if the aperture housing is mounted freely (within a movement space), the light intensity of the indirect light 712 can be easily adjusted mechanically by the angle of rotation.

[0094] Alternatively, the light-emitting component 114 may be attached to the aperture housing, and the rotational movement 1006 may change the orientation of the light-emitting component 114 relative to the support structure 902. This allows the emission direction of the light-emitting aperture 170 to be easily adjusted mechanically.

[0095] A light emitting aperture with a movable aperture having a combination of translational movement 902 of the Fig. 9A, Fig. 9B and rotational movement of the Fig. 10A, Fig. 10B (not illustrated) enables different lighting scenarios.

[0096] Fig. 11 is a schematic top view of an exemplary light-emitting aperture 170. The light-emitting aperture may include one or more sensory switching components 1102, such as a light intensity sensor or a motion sensor, depending on the application. The sensory switching component may be coupled to the control device and cause a switching from a first emission mode to a second emission mode, such as when a predetermined threshold is exceeded. The first emission mode may be, for example, an off-state or sleep mode with low light emission. The second emission mode may be an on-state or illumination mode, or vice versa.

[0097] Depending on the application, the sensory switching component can be arranged on sides other than the front side shown (also referred to as the panel side), for example on one of the side surfaces.

[0098] For example, a light intensity sensor can detect that the ambient light intensity is higher than a predetermined threshold, and the control device can then interrupt the power supply to the driver circuit. Illustratively, the light-emitting aperture 170 can be switched off when the ambient light intensity is sufficiently high.

[0099] For example, a motion sensor can detect the presence of a living being, such as a person or animal, by detecting a signal value higher than a predetermined threshold. The control device can then provide or amplify a power supply to the driver circuit. Illustratively, the light-emitting aperture 170 can be switched on when a person is detected in the surrounding area.

[0100] Fig. 12 is a schematic top view of an exemplary light-emitting aperture 170. The light-emitting aperture may include one or more mechanical switching components 1202, such as a rotary switch, a pushbutton, or a combination thereof, depending on the application. The mechanical switching component 1202 may be coupled to the control device and effect switching from a first emission mode to a second emission mode that differ in at least one characteristic. Fig. 12 illustrates an example of a rotary switch with an off mode "0," a first emission mode "1," and a second emission mode "2." The first emission mode and second emission mode can differ application-specifically in the light color, the correlated color temperature, the light intensity, or more complex predefined illumination profiles, for example, different emission directions. The mechanical switching component 1202 can have discrete switching stages (illustrated in Fig. 12) or continuously variable. The on / off state can be set by pressing a rotary push button, and the emission mode can be selected by turning the rotary push button.

[0101] The light-emitting panel 170 may further include a mechanical switching component 1202 (also referred to as a test button) configured to test the emergency lighting function. The test button may be coupled to the control device or connected upstream of the control device and de-energize the control device's power input (thus simulating a power failure). A power failure may be the activation of a residual current device (RCD) or an interruption of the power supply by the grid operator.

[0102] The mechanical switching component 1202 can be arranged on sides other than the front side shown, for example on one of the side surfaces, depending on the application.

[0103] Fig. 13A and Fig. 13B illustrate schematic top views of an exemplary light-emitting aperture 170. The frame-shaped light-emitting aperture 170 can be composed of two or more aperture segments 170-1, 170-2, which can be configured identically or differently. This allows an existing insert 130 of a flush-mounted box to be used for installing the light-emitting aperture 170 in the embodiments shown in Fig. 3A and Fig. 3B does not necessarily have to be disconnected from the power supply. The light-emitting aperture 170 can be assembled around the insert 130 (in Fig. 13B). The aperture segments 170-1, 170-2 can be mechanically, electrically and optically coupled to one another in a connection region 1302 (see also Fig. 6B), for example by means of a plug connection. A first aperture segment 170-1 can be U-shaped, for example spanning three sides of a quadrilateral, and a second aperture segment 170-2 can be web-shaped, for example spanning the fourth side of the quadrilateral, as in Fig. 13A. The control device can be arranged on the second aperture segment 170-2, for example. This allows for multiple interconnection of U-shaped first aperture segments 170-1, 170-3 (see Fig. 14A and Fig. 14B), for example, a parallel connection to enable a common light-emitting aperture 170 for several inserts 130-1, 130-2.

[0104] As an alternative to the U-shaped aperture segment 170-1 and the bar-shaped aperture segment 170-2, symmetrical L-shaped aperture segments can also be used, each spanning two sides of a quadrilateral. Alternatively, two U-shaped aperture segments can be used, each spanning half of one side and two sides of a quadrilateral, for example.
