Abstract
Description
[0001] The invention relates to a lighting device.
[0002] Lamps are commonly operated via manual switches, remote controls, or permanent wiring. Such solutions are often impractical for children, as they require additional controls, and incorrect operation or unintentional continuous illumination can occur.
[0003] The invention is based on the objective of providing a lighting device that is particularly easy to use, especially for children.
[0004] The problem is solved by a lighting device having the features of claim 1.
[0005] The lighting device according to the invention comprises a controllable luminaire designed to produce optical effects, a substantially flat base, and a switching system designed to control the luminaire so that it produces the optical effects when the lighting device is placed on a support surface with its base.
[0006] The invention is based on the idea of using a switching system to detect an environmental or state property of the installation (in particular, the presence of a flat contact surface) and then automatically controlling a light source. Simply establishing the installation state can trigger activation without requiring any further operating steps. In particular, the device is designed such that removing it from the surface deactivates it.
[0007] The device can be used in a variety of everyday situations. Examples include its use in a child's room as a calming light, its use during play and dance activities as a rhythmic disco light, or its use in living rooms and common areas to create a special atmosphere.
[0008] In particular, the device can function as a night light, providing gentle color changes or a soft, continuous illumination. Automatic shut-off after a preset time increases its suitability for everyday use in this application.
[0009] In another embodiment, the device can be used as a portable party light. Here, the focus is on dynamic optical effects that adapt to music or sounds and create an animated effect.
[0010] The device is particularly suitable for environments with children, as it can be activated simply by setting it up, without any controls. It is robust, child-safe, and offers a clearly defined range of functions, primarily limited to generating light. This prevents unintended use, such as could occur with more complex multimedia devices.
[0011] In particular, the device is so intuitive to use that even very young children understand how it works without explanation. The simple principle of "setting it up = light on, taking it down = light off" allows for child-friendly use without any potential hazards.
[0012] Furthermore, the device can also be used in educational or therapeutic settings, for example, to support music and movement games, promote concentration, or create calming environments. The device can be manufactured in series versions that differ in design, color, or lighting programs. This allows for adaptation to various age groups, markets, and price points.
[0013] The device is not limited to use in children's rooms, but can also be used in other environments, such as living spaces, educational institutions, leisure facilities or mobile contexts.
[0014] The device is specifically designed to meet the needs of children. This is evident in its particularly simple operation, the limitation of the light intensity, and its robust construction.
[0015] However, the device can also be of interest to adults, for example as a design object, a mood lamp, or a portable party light. More intense or complex optical effects can also be incorporated in these applications.
[0016] The device can be offered in different versions for various age groups. Simple, gentle effects with automatic shut-off are particularly suitable for younger children, while more complex, interactive sequences can be provided for older users.
[0017] The possibility of using the device on various devices, its connection via signals, and its adaptability to target groups result in a high degree of flexibility for the device according to the invention. This opens up a wide range of applications, from child-friendly uses to universal lighting solutions.
[0018] In addition to standard models, special versions may also be provided, for example with integrated projection elements, extended effect programs or special materials for the housing.
[0019] For the purposes of the invention, an “optical effect” is understood to mean any phenomenon produced by the luminaire, in particular one visible to the human eye, especially a change in the intensity of the light, the color, the pattern, the direction or the projection of the light.
[0020] The switching system can comprise one or more switching elements that operate mechanically, electrically, magnetically, optically, or electronically to activate or deactivate the light source. The switching system can also include a microcomputer or similar device. In particular, the switching system includes a control unit that operates the lighting device. The control unit can process additional signals, such as those provided by sensors or a sound detection unit.
[0021] The term "base" refers to the area of the device that is in contact with a surface when it is set up. The contact surface is the corresponding surface of the surroundings, e.g., a table or floor, thus the "base." The statement that "the lighting device is set up with its base on the contact surface" means that the lighting device is positioned on the contact surface in such a way that the base and the contact surface are in full-surface contact.
[0022] A light source is defined as any component that actively emits light, in particular one or more light-emitting diodes (LEDs), a lamp, a display, or a projection system. Specifically, a light source includes radiating elements (preferably LEDs) that produce optical effects, including colored or white emission, static displays, or dynamic patterns. Gentle, continuous effects that are low-stimulus and suitable for children are particularly preferred.
[0023] The device is specifically designed to provide continuous or rhythmically smoothed optical effects for periods of at least several seconds. Short, purely confirmation-like signal flashes are not the primary focus. Activation occurs immediately or with a defined delay solely based on the detected installation status.
[0024] Stabilizing means (especially a magnet) can be used to hold the device on suitable surfaces and / or to influence the switching state.
[0025] Activation can be achieved through different switching principles, including, but not limited to, mechanical, magnetic (e.g., field-dependent contacts), electrical, capacitive, or optical sensors.
[0026] In a further embodiment, the switching system includes a sensor configured to detect when the lighting device is placed with its base on the support surface. The switching system is further configured to control the light source when the sensor detects that the lighting device has been placed with its base on the support surface. The sensor is preferably configured to detect whether the base is touching the support surface or is in close proximity to it, and is preferably designed as a reed switch, Hall sensor, pressure contact sensor, capacitive sensor, or optical sensor.
[0027] The device can include various sensors, preferably located in the base area. There, they can reliably detect whether a contact has been made in the setup position. These include reed switches, Hall sensors, pressure contacts, capacitive sensors, or optical sensors.
[0028] In a first embodiment, a reed switch is arranged in the base of the device, which reacts to the presence of a magnetic field. When the device is placed on a magnetically active surface or on a base equipped with magnets, the circuit closes and the light is activated. When removed, the circuit opens and the light goes out.
[0029] In another embodiment, the switching system comprises a mechanically actuated switch, which is activated by placing the lighting device on the support surface with its base. The switching system controls the light source as a result of the switch being actuated. The switch preferably has a pin protruding from the base and which can be pressed into the base, closing an electrical contact when pressed into the base.
[0030] Using a mechanically actuated switch allows for a robust, cost-effective, and reliable method of automatically activating the optical effects. Such a switch can also be called a push-button switch. The fact that the switch is mechanically actuated offers an advantage over the previously described magnetic sensors: it reduces the risk of unwanted environmental influences. Pins protruding from the base, which can be pressed into the base to close an electrical contact, represent a particularly simple mechanical implementation of the switch. Closing the contact, in particular, establishes an electrical connection between the light source and a power supply.
[0031] In a further embodiment, the switching system comprises, in addition to the switch of the embodiment described above, at least one further identical mechanically actuated switch. Furthermore, the switching system is designed to activate the light source only when a predetermined minimum number of switches are actuated simultaneously, for example, two or more switches at the same time. The at least one further mechanically actuated switch is also actuated by placing the lighting device with its base on the support surface. The at least one mechanically actuated switch may preferably also have pins projecting from the base that can be pressed into it, and which close an electrical contact when the pin is pressed into the base.
[0032] In this embodiment, at least two mechanically actuated switches are present, and the minimum number of switches must be actuated simultaneously to produce the optical effects. Actuating a single switch is therefore insufficient. This has the advantage that the optical effect is only produced on flat surfaces and when the device is fully upright. Furthermore, it is advantageous that accidental activation by manual operation is made more difficult, especially for children, who would have to press the minimum number of switches simultaneously.
[0033] In another embodiment, activation occurs via a pressure contact that is actuated by the weight of the device on the surface. This solution requires no magnetic counterparts and can be used on any flat surface.
[0034] An alternative embodiment provides for the use of a capacitive sensor that detects changes in electrical properties during setup and converts them into an activation signal for the light source.
[0035] All described switching principles are considered equivalent alternatives. The invention is not limited to a specific embodiment, but encompasses all variants that provide an activation signal generated depending on the setup.
[0036] In another embodiment, a magnet is provided which fixes the lighting device to the metal surface when it is placed on a magnetic metal surface.
[0037] In another embodiment, the switching system is designed to detect a change in the magnetic field generated by the magnet as a result of being placed on the magnetic support surface.
[0038] In another embodiment, a noise detection device is provided which is designed to perceive ambient noise, wherein the switching system is designed to adapt the optical effects to the perceived ambient noise.
[0039] In particular, the device can be designed to detect frequencies or volumes of music or speech and generate rhythmic changes in color or intensity that correspond to these signals. This enables a high degree of interactivity and enhances the playful effect when used by children. Furthermore, the device can be designed so that the light output reacts interactively to external stimuli. This includes, in particular, acoustic signals, movements, or other environmental conditions.
[0040] In particular, the device is designed to include a microphone or sound sensor that detects ambient noise. The control unit can then derive information about volume, rhythm, or frequency spectrum from this data and adjust the light output accordingly.
[0041] Alternatively or additionally, the device can react to other environmental parameters, such as nearby movements or the switching on / off of an external device. This means the solution is not limited to music-controlled scenarios but is widely applicable.
[0042] The device according to the invention can be operated individually or used in combination with other electrical or electronic devices. In particular, it can be positioned on device surfaces that already have a primary function, such as playback devices, consoles, computers or household appliances.
[0043] The device is particularly suitable for combination with audio playback systems. It can be used in such a way that the generated optical effects provide a complementary visual component to the acoustic output. It is irrelevant whether the playback system uses figures, maps, digital media, or other control objects.
[0044] The invention is not limited to a specific type of control or effect design. Rather, it encompasses all variants in which controlled light output with static or dynamic effects is achieved through automatic activation upon setup.
[0045] In another embodiment, the switching system is designed to adapt the optical effects to the rhythm of detected music or speech.
[0046] Particularly popular is the coupling of visual effects with the rhythm of music or speech. The lighting can be controlled synchronously or proportionally to the timing of sounds, creating the impression of a visual accompaniment to the music.
[0047] Alternatively or additionally, the optical effects can also be coupled to other stimuli, such as motion detection, approach of people, changes in ambient brightness or temperature changes.
[0048] In particular, the visual effects can be controlled to adapt to the rhythm or dynamics of external acoustic signals. It is irrelevant whether the signal originates from a playback device, an external source, or the environment.
[0049] In a further embodiment, a reading module is provided which is designed to read information from a data carrier, wherein the switching system is designed to generate and / or change the optical effects depending on the information read out.
[0050] The device can include one or more sensors or reading modules designed to read information from a data carrier. This can be done via contact surfaces, magnetic codes, RFID, NFC, optical markers, or other identification methods.
[0051] The read information is processed by the control unit and triggers a corresponding light pattern. This makes it possible for different data carriers to activate different color sequences, projections, or light sequences.
[0052] In particular, game figures can serve as data carriers, each triggering its own program for a visual effect when placed or approached. This allows for playful and varied use without playing any audio content.
[0053] Furthermore, it is possible that a variety of different data carriers are available, allowing users to customize the visual appearance of the device by selecting specific figures or objects.
[0054] Unlike known systems that play audio content upon detection of an identifier, the present invention serves exclusively for the visual output of optical effects. Audio playback is neither required nor provided for.
[0055] One advantage of this design is that children can easily control the device's visual properties by selecting specific figures or objects. Operation remains intuitive and child-safe.
[0056] Furthermore, this solution offers great variability, as any number of data carriers, each with different light patterns, can be used. This results in high play and collector value.
[0057] The technical implementation can be achieved through various methods, e.g., contactless identification (RFID / NFC), magnetic coding, mechanical keying, or optical recognition systems.
[0058] The invention thus also includes embodiments in which the visual control of light patterns is achieved via data carriers. This solution significantly expands the possible applications, but remains clearly distinct from known systems whose main function is audio playback.
[0059] The device can be designed to react to the approach or placement of specific data carriers. For the purposes of this invention, data carriers are understood to be any objects that can provide unambiguous information, such as figures, maps, or electronic storage devices.
[0060] The device can also receive or evaluate signals from external devices. These can be acoustic signals, electrical control signals, wireless transmissions, or other suitable forms of communication.
[0061] In particular, it is possible to equip the device with wireless interfaces, such as Bluetooth, Wi-Fi, or infrared. This allows synchronization with external devices, for example, to control light sequences, select color programs, or synchronize with music.
[0062] Alternatively, the device can also be connected to external devices via wired connections, for example, via a simple power or data interface. These interfaces preferably serve not as a mandatory requirement, but as an optional extension.
[0063] In another embodiment, a power supply is provided to which an external electrical energy storage device, for example batteries or accumulators, can be connected, and / or to which an external power source can be connected, and / or which is connected to a rechargeable internal energy storage device that is attached to the device.
[0064] The power supply can be provided by batteries, accumulators, or external power sources. There is no fixed requirement regarding this; all forms of energy are included as long as they provide the necessary electrical power.
[0065] The power supply is preferably designed in such a way as to prevent any hazards. This includes insulated contacts, sealed battery compartments, and overcharge protection circuits for rechargeable versions.
[0066] The device can be powered by any electrical means, including batteries, accumulators, power supplies, inductive charging systems, or equivalent power sources. The device is preferably designed to operate independently of a fixed cable connection, thus allowing for flexible placement on a wide variety of surfaces.
[0067] In particular, the device can include a rechargeable energy storage device that can be recharged via any charging interface. The specific charging mechanism (e.g., inductive or wired) is not restricted, so future developments are also included.
[0068] In another embodiment, the switching system includes an energy management unit designed to control the light intensity of the optical effects or the operating time of the luminaire.
[0069] The device can include a power management unit that optimizes the operation of the LEDs. This unit can control energy consumption, prevent overcharging or deep discharging, and adjust the light intensity to the available energy.
[0070] In particular, the device may be designed to have energy-saving modes in which the light output is reduced or only certain effect programs are activated. This extends the operating time in mobile applications.
[0071] Optionally, an energy management system can be integrated to optimize operating time, control charging cycles, and prevent overloads. This contributes significantly to a longer device lifespan.
[0072] In another embodiment, the light source has a lens, aperture or dome with which patterns or colors can be projected onto an environment.
[0073] The device can also include additional functions that expand its range of applications. These include, for example, the projection of patterns onto walls or ceilings, the integration of sound signals (e.g., short acoustic feedback), or the possibility of coupling with external control devices.
[0074] The light source can include a dome, a hemispherical cover, a lens, or another translucent element. In particular, the light source can be designed so that the generated optical effects are projected across walls and ceilings, creating a particularly atmospheric ambiance.
[0075] In particular, the device can feature a semi-transparent dome or lens that distributes the generated optical effects as moving patterns in space. This creates a particularly intense and atmospheric effect for the user, extending the experience beyond mere light emission.
[0076] In another embodiment, the light source comprises a plurality of LEDs, and the optical effects include a change in the brightness and / or color of the LEDs. Preferably, the LEDs are at least partially controllable differently to generate the optical effects, in particular so that they produce patterns.
[0077] In particular, the light source can contain one or more light-emitting diodes (LEDs) that produce different colors. The control can be fixed or variable, resulting in color changes, color gradients, or rhythmic sequences.
[0078] In another embodiment, the optical effects comprise different brightness sequences and / or color sequences and / or projections generated by the luminaire, wherein a change in the optical effects comprises a change in these brightness sequences, color sequences or projections.
[0079] The device according to the invention can generate various optical effects. These can be static, dynamic, uniformly changing, or random. Optical effects are understood to mean, in particular, changes in color, intensity, or light distribution.
[0080] In particular, the light source is designed to emit multicolored light. This can be achieved by combining several LEDs operating in different primary colors (e.g., red, green, blue, white, or others). Through additive mixing, virtually any color variation can be displayed.
[0081] Furthermore, light sequences can be generated that are either pre-programmed or adaptively controlled. These sequences can include color changes, pulsating patterns, transition effects, or smooth gradients.
[0082] The device's light characteristics can be configured in various ways. These include smooth color changes, random color sequences, pulsating optical effects, or projection-like illumination. All variants share the common feature of operating within a safe, low-stimulus intensity range.
[0083] In another embodiment, the light source produces an illuminance of a maximum of 500 lux, preferably a maximum of 200 lux.
[0084] The device is preferably designed such that the generated light output does not exceed a defined, child-safe limit. Child-safe means, in particular, that the light intensity and the frequency of the optical effects do not cause overstimulation or damage to eyesight.
[0085] In another embodiment, a housing is provided that surrounds the current-carrying components of the lighting device in such a way that they are not accessible from the outside, the housing preferably meeting the requirements of EN IEC 62115:2020 + A11:2020 (Electrical toys - Safety).
[0086] The entire device is designed to prevent the generation of dangerous temperatures, sharp edges, and detachable small parts. Electrical components are preferably encapsulated or arranged so that they are not accessible from the outside.
[0087] In particular, the device is designed to meet relevant safety standards for children's products, such as the aforementioned EN IEC 62115:2020 + A11:2020. These standards include requirements for electrical safety, mechanical strength, and the use of materials compatible with health. The device is therefore ideally suited for use in children's rooms. The device in general, and the housing in particular, can also be designed to meet the requirements of EN 71-1, EN 71-2, and EN 71-3. It thus complies with Directive 2009 / 48 / EC.
[0088] In particular, the device comprises a shock-resistant, robust housing, which may be made of plastic, composite materials, or other durable materials. It is preferred that the surfaces are matte or glare-free to reduce reflections and provide a pleasant feel.
[0089] The device can be implemented in various geometric shapes. In particular, a compact light source can be provided, mounted on a support element. Alternatively, the entire device can also be uniformly spherical, cylindrical, or prismatic. The invention is therefore not limited to a specific external shape.
[0090] In particular, the device is designed so that children can easily grasp, set up, and remove it without small parts coming loose or dangerous components being exposed. Its operation is kept as simple as possible, allowing even very young children to use it intuitively.
[0091] By combining automatic activation upon setup, child-safe design, variable power supply, robust housing and optional interactive control (e.g. music rhythm), the invention provides a universally applicable, safe and versatile lighting device that differs significantly from known solutions.
[0092] The device according to the invention can be implemented in various embodiments. These embodiments have in common that they provide for automatic activation when placed on a surface, whereby the light source generates optical effects. Differences arise in particular from the choice of switching principle, shape, materials, and type of power supply.
[0093] In another embodiment, the housing can be opened and then closed again, with the light source, the power supply, the internal energy storage and / or the external electrical energy storage being interchangeable.
[0094] In another embodiment, the base and the light source form opposite ends of the lighting device. The total length of the lighting device between these ends is less than 15 cm, and a housing section with a diameter between 1 and 5 cm and a length of at least 5 cm is arranged between the base and the light source.
[0095] The device can be designed as a modular system in which individual components – such as the light source, control unit, or power supply – are interchangeable or expandable. This allows the product to be adapted to different user needs.
[0096] In particular, it may be provided that the device can accommodate accessory modules that enable additional effects, e.g. interchangeable skylights, decorative attachments or projection elements.
[0097] The device can be manufactured using common manufacturing processes for plastic and electronic components. These include, in particular, injection molding processes for housing parts as well as assembly and soldering processes for electronic components.
[0098] In particular, the materials used are intended to be free of harmful substances and to comply with relevant standards for children's toys or lighting equipment. The housing is designed to be mechanically stable and secured against unintentional opening.
[0099] The housing surface can be finished in different variations, such as matte, textured, or smooth. This allows for different tactile and visual impressions that can be tailored to the respective target group.
[0100] The device's design is therefore flexible, allowing for both a simple standard version with fixed components and a high-quality modular variant with interchangeable or expandable parts. This opens up a wide range of design possibilities for different markets and target groups.
[0101] The device can consist of several functional housing parts. Typically, it includes a lower part containing the stabilizing elements and the power supply, and an upper part that holds the light source. Both parts can be detachably or permanently connected.
[0102] In particular, it is possible to design the housing in a multi-part construction, which allows for easy assembly, maintenance, or replacement of individual components. This makes it easy to replace or retrofit batteries, rechargeable batteries, or LEDs.
[0103] In another embodiment, a loudspeaker is provided which is designed to emit sounds, in particular signal tones and / or melodies.
[0104] In another embodiment, the switching system is designed to control the luminaire so that it ceases generating the optical effects as a result of the lighting device being removed from the support surface.
[0105] Furthermore, the device is preferably designed to switch off automatically when removed from the mounting surface, when the magnetic field weakens, or after a defined period of inactivity. This increases both energy efficiency and safety.
[0106] In particular, the device can include an internal timer or sensor-based shut-off logic that automatically deactivates the lighting after an adjustable duration. This is especially advantageous for use as a nightlight, where falling asleep with soft light followed by automatic darkness is desired.
[0107] The device is optimized for regular use in children's environments. This includes high mechanical strength, a long lifespan for the light elements, and a power supply designed for extended periods of use.
[0108] The device according to the invention can have various stabilizing means that ensure secure positioning. Besides a magnet, these can be weights, friction-optimized base surfaces, or mechanical holding elements. Combinations of several stabilizing means are also possible.
[0109] In particular, a preferred embodiment includes a magnetic system that ensures the secure holding of the device on metallic surfaces. The magnetic system can also be part of the switching mechanism by interacting with a reed switch, a Hall sensor, or another magnetic field-dependent switching element.
[0110] Alternatively or additionally, the device can be stabilized by shifting the weight in the lower area. In this case, the housing is designed to create a low center of gravity, making the device stable even without magnetic support.
[0111] Although the device is designed to operate without a switch, further embodiments allow for optional controls. These can be used, for example, for manual activation, switching between operating modes, or deactivation.
[0112] In particular, any existing controls may be concealed, so that children continue to perceive the device as functioning automatically in everyday use. A hidden button, a recessed switch, or a concealed sensor layer can allow adults to change the operating mode or activate a lock function.
[0113] The device is preferably designed to prevent or reduce unintentional activation. This can be ensured by a minimum load, a defined contact area, a magnetic field threshold, or a time delay during activation.
[0114] The device is preferably designed to be shockproof, drop-resistant, and insensitive to normal wear and tear during daily use by children. In particular, the housing has rounded edges, no sharp corners, and no small parts that can be detached, so that the device can be used safely in a child's room.
[0115] The device can preferably be positioned on a device surface that serves as a platform for activation. Device surfaces are understood to be, in particular, surfaces of audio playback devices, gaming systems, pieces of furniture, or other everyday objects. The invention is not limited to a specific type of device.
[0116] The device is designed so that other objects can be placed on the same surface simultaneously. These can include, in particular, toy figures, decorative items, or accessories. The lighting device does not interfere with the placement of such objects but rather allows for their concurrent use.
[0117] The device is particularly suitable for use in combination with children's play systems where figures, cards, or similar objects are placed on a surface. The lighting serves as a complementary visual experience that increases children's attention without restricting the system's original purpose.
[0118] Alternatively, the device can also be used independently of any other device. In this case, it is simply placed on a suitable surface, such as a table, floor, or shelf. Activation is achieved solely by making contact with the surface it is placed on.
[0119] In particular, the device's compact design and integrated power supply make it portable and allow for flexible use in different locations. This makes it suitable for both stationary use in a child's room and for mobile use at parties, while traveling, or outdoors.
[0120] The external design of the device can be variable, as long as its functionality according to the invention is maintained. In particular, different shapes, colors, and surface textures can be chosen to adapt the device to different age groups, tastes, or environments.
[0121] In particular, it is possible to produce the device with thematic designs tailored to children's worlds, characters, or stories. This can be achieved through color schemes, prints, or the inclusion of decorative elements without altering the core of the invention.
[0122] The design is preferably such that the device can be placed on various devices, platforms, or surfaces without impairing their intended use. In particular, the geometry allows other objects to be positioned on the same surface simultaneously.
[0123] The device according to the invention allows for intuitive, switchless operation, safe and pleasant light emission, robust everyday suitability and a high degree of flexibility in terms of switching principle, energy supply and form factor.
[0124] The invention is explained in more detail below with reference to exemplary embodiments shown in the accompanying drawings. The drawings show: Fig. 1a, Fig. 1b: Schematic side views of a lighting device in a non-erected and an erected state, Fig. 2a, Fig. 2b: Schematic side views of a lighting device with a switch comprising a pin, Fig. 3a, Fig. 3b: Schematic side views of a lighting device with multiple switches including pins, Fig. 4a-4c: Schematic side views of lighting devices with various housings and Fig. 5a, Fig. 5b: Schematic side views of a lighting device that reacts to ambient noise.
[0125] The same reference symbols are used in all embodiments for identical features.
[0126] Fig. Figure 1a shows a lighting device 1 in a schematic side view, with components arranged inside the lighting device 1 also shown.
[0127] The lighting device 1 comprises a light source 2 and a substantially flat base 3, which allows the lighting device 1 to be placed on a support surface 4. In this example, the top of a media playback device 5 forms the support surface 4. The support surface 4 can be a metal surface.
[0128] The luminaire 2 comprises a unit 6, which integrates LEDs and a control unit for controlling the LEDs, as well as a dome 7. Light generated by the LEDs is refracted by the dome 7. The LEDs can be controlled in various colors and brightness levels. Individual LEDs can be controlled to create different optical effects. For example, patterns or various lighting sequences with alternating brightness levels can be produced. The dome 7 helps to ensure that the optical effects have the desired characteristics. The dome 7 could also be replaced by another element, such as a lens or aperture.
[0129] A magnet 8 and, in the illustrated embodiment, a reed switch 9 are arranged at one lower end of the lighting device 1. However, another comparable type of sensor, such as an inductively switching sensor, can also be used. The reed switch 9 is connected to the unit 6 via a signal connection 10. When the reed switch 9 detects that the lighting device 1 has been placed on the support surface 4 with its base 3, the control unit of the unit 6 activates the LEDs to produce the optical effects.
[0130] The unit 6 receives the necessary electrical energy from the integrated energy storage device 11, which is designed, for example, as a rechargeable battery. The energy storage device 11 is connected to the unit 6 via a current-carrying connection 12.
[0131] In particular, unit 6, magnet 8, reed switch 9, and energy storage device 11 are arranged in a housing 13. This housing surrounds the live components—specifically unit 6 with the LEDs and control unit, as well as the energy storage device 11—so that they are not accessible from the outside. The lighting device 1 in general, and the housing 13 in particular, comply with the requirements of EN IEC 62115:2020 + A11:2020, so that the lighting device 1 can be used safely by children.
[0132] A cylindrical housing section 14.1, positioned between the lower end formed by the base 3 and the upper end formed by the light source 2, has a diameter of, for example, 2.5 cm. It is particularly easy for a child to grasp. The housing section 14.1 may, for example, have a length of 7.5 cm. The overall length of the lighting device 1 may be 13.5 cm.
[0133] Fig. Figure 1b shows the lighting device 1 after it has been placed on the support surface 4 of the device 5 for media playback, with its base 3 resting on this surface. The reed switch 9 has detected this. The unit 6 subsequently generates the optical effects 15, which are stylized and represented by arrows. The optical effects 15 can therefore be switched on without having to operate any separate controls. Removing the lighting device 1 from the support surface 4 switches off the optical effects.
[0134] In particular, the unit 6 with the LEDs and the control unit, the reed switch 9 and the signal connection 10 together form a switching system in this embodiment, which is designed to control the light source 2 so that it produces the optical effects 15, as a result of the lighting device 1 being placed with the base 3 on a support surface 4.
[0135] A toy 16 is also arranged on the support surface 4. The housing 13, in particular housing section 14.1, is designed such that the toy 16 is arranged completely below the light source 2. If the toy 16 has already been placed on the device 5 for media playback, the lighting device 1 can be added. It then provides suitable illumination. The toy 16 can also be added if the lighting device 1 is already on the support surface 4.
[0136] Positioning the toy 16, which may, for example, be in the shape of an animal or a person, on the media playback device 5 can cause the device 5 to generate sounds—for example, music or the playback of a narrated story—where the music or story can correspond to the shape of the toy 16. In the lighting unit 1, the unit 6 can, for example, include a reading module that can also be configured to recognize the toy 16, and the unit 6 can be configured to subsequently generate a suitable optical effect or modify the existing optical effect.
[0137] Fig. Figure 2a shows a schematic side view of another lighting device 1 according to the invention. This device has a switch 17, which is actuated by placing the lighting device 1 with its base 3 on the support surface 4. As a result of actuating the switch 17, the switching system controls the light source 2, so that the light source 2 produces the optical effects 15. The switch 17 has a pin 18 projecting from the base 3, which can be pressed into the base 3 and closes an electrical contact between the electrical conductors 19.1 and 19.2 when pressed into the base 3. Then the conductors 19.1, 19.2, 19.3, the unit 6 with the LEDs, the energy storage device 11, and the pin 18 form a closed electrical circuit, which ensures that the optical effects 15 are produced.
[0138] In Fig. 2b the lighting device 1 is placed on the support surface 4. As explained above, this presses the pin 18 into the base, producing the optical effects 15, as indicated by the arrows.
[0139] Fig. 3a and Fig. Figure 3b shows a schematic side view of a lighting device 1 with several switches 17, which function as previously described in connection with Fig. 2a and Fig. 2b explained. The switches 17 therefore include pins 18 which can be pressed into the base 3.
[0140] In this embodiment, all pins 18 must be pressed in so that the electrical circuit comprising lines 19.1, 19.2, 19.3 is closed and the optical effect 15 is generated. Therefore, in this example, a minimum of three switches 17 must be actuated simultaneously for the optical effects 15 to be generated. Fig. Figure 3a shows that the lighting device 1 is not yet placed on the support surface 3, while in Fig. 3b the lighting device 1 is placed on the support surface so that the pins 18 are pressed into the base 3, the electrical circuit is closed and the optical effect 15 is produced.
[0141] Fig. Figures 4a-4c show schematic side views of other lighting devices 1.
[0142] These differ in their various housings 13. In principle, they can be designed like the lighting device 1, which was previously described in connection with the Fig. 1a-2b was explained.
[0143] The lighting device 1 in Fig. 4a is shown in section and has a housing 13 with a hollow cylindrical housing section 14.2. The hollow cylindrical housing section 14.2 can be placed over a toy 16.
[0144] The in Fig. The lighting device 1 shown in 4b has an arc-shaped housing section 14.3 that can span a toy 16.
[0145] Fig. Figure 4c shows a lighting device 1 with a projecting housing section 14.4 that can accommodate a toy 16.
[0146] The housing can be configured in the exemplary embodiments as follows: Fig. 4a-4c, for example, could be designed in the form of a house or something similar to bring joy to children while they play.
[0147] Fig. 5a and Fig. Figure 5b shows schematic side views of a lighting device 1 that reacts to ambient noise. It has a noise detection unit 20, which is connected to the unit 6, which includes the LEDs and the control unit. When the noise detection unit 20, which can be, for example, a microphone, detects an ambient noise 21 that is in Fig. When 5b is represented as a treble clef, it adjusts the visual effects 15. This is in Fig. 5b is represented by the fact that the arrows symbolizing the optical effects 15 are shown in different lengths. Adjusting the optical effects 15 can involve controlling individual LEDs so that their brightness or color changes. In this way, for example, patterns can be created or lighting that pulses to the beat of the music.
