Description

The present invention relates to a lamp comprising a fastening unit for fastening a user interface device and a system comprising such a lamp and a user interface device.

To control the light output of a floor lamp by a user, the floor lamp as an input device ("input device") typically both a button and / or switch on the floor lamp and an optical sensor for detecting wireless signals in the form of optical radiation, such as Infrared radiation radiated remotely by a user interface device in response to operator input at the user interface device. Such a user interface device may be a remote control configured to send wireless signals by emitting infrared radiation. Consequently, by pressing the button on the floor lamp or by pressing the user interface device, for example a button element of the user interface device, a user can control the light output of the floor lamp, for example switching it on and off and optionally dimming it or setting other functions of the lamp. The manipulation of the user interface device by the user causes the wireless signals to be emitted in the form of optical radiation, the wireless signals being dependent on the user input.

The terms "sensing", "detecting" and "recognizing" can be used as synonyms. The terms "detector" and "sensor" can be used as synonyms.

Optical radiation includes ultraviolet radiation (UV radiation), visible light or visible radiation (VIS radiation), and infrared radiation (IR radiation). In other words, optical radiation corresponds to electromagnetic radiation (electromagnetic waves) in the wavelength range from 100 nanometers (100 nm) to 1 millimeter (1 mm) of the electromagnetic spectrum.

The button and/or switch as well as the user interface device can each comprise at least one button element, such as at least one push button, at least one push button, etc., and/or at least one switch, such as at least one rotary switch, toggle switch, rocker switch, etc. The button and/or switch as well as the user interface device can each be designed in the form of a touch panel, for example.

A floor lamp (which may also be referred to as a floor lamp) typically includes a light source portion (which may also be referred to as a head portion) including at least one light source for providing the light output of the floor lamp and a base portion (which may also be referred to as a mast). The illuminant section is fastened to the stand section at a height starting from a surface on which the floor lamp can be positioned. The floor lamp may include an optional base section (which may also be referred to as a base) for positioning the floor lamp on the surface. The main direction of light emission from a floor lamp can be in the direction of the surface on which the floor lamp can be positioned and/or opposite to the aforementioned direction (towards the ceiling of a room). Examples of a floor lamp are uplighters with an optional reading lamp, table lamps (such as a desk lamp), reading lamps, etc.

In lamps, such as the above-mentioned floor lamp, the individual electrical components of the lamp (such as sensors, driver modules for operating or supplying electricity to lamp modules, a control unit for controlling the light output of the lamp, etc.) can be connected to one another via a wired bus be electrically connected in order to be able to communicate with each other. If a floor lamp comprises both a button on the floor lamp and an optical sensor for detecting wireless signals in the form of optical radiation, as described above, then this button is connected to the bus via a button module and this optical sensor. Consequently, an actuation of the button by a user and a detection of wireless signals by the optical sensor (when the user interface device is actuated and the wireless signals are emitted in the form of optical radiation) can be communicated to a control unit of the floor lamp via the bus and the control unit can then be dependent control the light output of the floor lamp.

The lighting of the floor lamp can be controlled according to the DALI industry standard or DALI-2 industry standard. In other words, the electrical components of the floor lamp, in particular the button, the button module, the optical sensor, the bus, the control unit, etc., can be DALI-compatible components (also referred to as DALI components or DALI-2 components) or DALI-2 compatible components (also referred to as DALI-2 components or DALI-2 components).

The term " DALI-2 " refers to the industry standard according to "IEC 62386 Edition 2" of the International Electrotechnical Commission, which is the successor industry standard to the industry standard called "DALI" ( "Digital Addressable Lighting Interface" ) or DALI, Edition 1 is The term "DALI-2" stands for " Digital Addressable Lighting Interface, Edition 2 " . DALI (DALI, Edition 1) and DALI-2 (DALI, Edition 2) are well-known industry standards in the technical field of lighting.

For a control unit connected to a bus, such as the DALI bus or DALI-2 bus, there is no difference between a command that is transmitted over the bus from the button module when the button connected to the bus via a button module is operated by a user and a command transmitted from the optical sensor via the bus when the optical sensor detects optical radiation emitted by the user interface device in response to a user manipulation of the user interface device.

Typically, the button is mounted in a floor lamp in the standing section or in the optional foot section, since it can easily be actuated by a user, for example by hand or foot, at these points on the floor lamp. As a result, electronics such as a power supply, the bus for communication between the button and other electrical components of the light and the button module must be accommodated in the stand section. However, there is only little space within the standing section of the floor lamp, so accommodating the electronics for the button is difficult, complex and expensive. If the electronics for the button are housed in an external box on the surface of the floor lamp, problems can arise with regard to electromagnetic compatibility (EMC problems) due to the excessively long cable lengths of the power supply and the bus. The electronics for connecting the operating unit to the bus can also be accommodated in the base or in the head of the lamp, whereby the electrical connection of the button to the electrical supply and communication also requires cabling in production and the need for plugs with more contacts.

The above disadvantages of a button are given not only in floor lamps, but also in other types of lamps. This is particularly the case when the button is to be provided at a point on the lamp where there is little space for the electronics that must be provided for the button.

In the light of this prior art, it is therefore an object of the present invention to provide a lamp that overcomes the disadvantages described above while providing the same functionality for the user.

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 lamp with a sensor unit and a fastening unit is provided. The sensor unit includes at least one optical sensor set up to detect optical radiation. The sensor unit is preferably a presence and/or motion sensor unit. The attachment unit is set up to attach a user interface device to the lamp, the user interface device being set up to emit optical radiation. The attachment unit is arranged in such a way that the at least one optical sensor of the sensor unit is set up to detect the optical radiation that can be emitted by the user interface device when the user interface device is attached to the luminaire by the attachment unit.

In other words, the above invention proposes providing a fastening unit for fastening a user interface device to the lamp instead of a button permanently attached to the lamp so that the user can control the light output of the lamp. This attachment unit is arranged on the light in such a way that the at least one optical sensor (i.e. one optical sensor or multiple optical sensors) of the sensor unit can detect the optical radiation that can be emitted by the user interface device when the user interface device is attached to the light by the attachment unit. Consequently, wireless signals in the form of optical radiation can be sent to the sensor unit of the lamp both remotely and through the user interface device when the user interface device is attached to the lamp by the attachment unit. The user interface device is configured to transmit such wireless signals in the form of optical radiation in response to the user manipulating the user interface device to control the light output of the luminaire.

In both cases, the at least one optical sensor can detect the optical radiation and consequently the wireless signals and forward them to a control unit of the lamp, which is set up to adjust the light emission of the lamp depending on the detection result of the sensor unit and thus on the detected wireless signals Taxes.

Therefore, the lamp according to the invention allows the same functionality for the user to control the light output of the lamp, but without the disadvantages described above with regard to a button, in particular the considerable amount of wiring. The user can use the user interface device to control the light emission both remotely (if the user interface device is not attached to the luminaire) and locally directly on the luminaire (if the user interface device is attached to the luminaire by the attachment unit) the light emission by operating the user interface device control wirelessly. Accordingly, the lamp according to an aspect of the present invention achieves the above object.

The above statements regarding a user interface device apply correspondingly to the user interface device that is attachable (i.e. can be attached) to the luminaire by the attachment unit.

In addition to the at least one optical sensor, the sensor unit preferably comprises at least one other type of sensor, for example at least one sensor for detecting the presence and/or movement of a person and/or an object, at least one sensor for detecting the light output of the lamp, at least one sensor for detecting daylight and/or at least one sensor for detecting ambient light. The sensor unit is not limited to a specific sensor arrangement and can therefore be configured in any manner known to those skilled in the art. The at least one optical sensor and/or the at least one further optional sensor of the sensor unit can each be a sensor field of the sensor unit.

The sensor unit is preferably a presence and/or motion sensor unit which is set up to detect or detect the presence and/or movement of a person and/or an object and optionally to detect or detect daylight. The at least one optical sensor can be a sensor field of the sensor unit. The sensor unit is preferably dome-shaped, with the dome being set up to detect the presence and/or movement of a person and optionally daylight, and the at least one optical sensor is a sensor field of the sensor unit.

The sensor unit can be arranged inside the lamp and/or on the surface of the lamp. In other words, the sensor unit can be arranged on the inside and/or on the outside of the lamp. The sensor unit can be integrated in the lamp.

The fastening unit can be set up to fasten the user interface device to the lamp in a non-positive, form-fitting and/or material-locking manner. In particular, the fastening unit comprises or corresponds to at least one fastening element. The at least one fastener may be at least one of a clip, a clip, a magnetic fastener, a click fastener component, a snap fastener component, a male fastener component, a snap-in fastener and/or a slide fastener component, etc. The user interface device is configured to be able to be attached to the lamp by the attachment unit.

Preferably, the attachment unit comprises one or more magnets for detachably attaching the user interface device to the lamp. Here, for an accurate Positioning of the user interface device on the lamp, the attachment unit can optionally be set up for mechanical centering/orientation.

Preferably, the attachment unit is implemented as a snap-in attachment that includes one or more latches for attaching the user interface device.

The fastening unit is not limited to a specific fastening unit and can therefore be designed in any way known to the person skilled in the art. The terms “mount” and “fixing unit” can be used synonymously for the term “fastening unit”.

The user interface device is configured to emit optical radiation for transmission of wireless signals. The user interface device is set up in particular to emit optical radiation depending on a user input on the user interface device. In other words, the user interface device is set up to send commands for controlling the light output of the lamp, which are entered by a user at the user interface device, as wireless signals to the at least one optical sensor of the lamp by a corresponding emission of optical radiation. Since the at least one optical sensor of the sensor unit of the lamp is set up to detect optical radiation, these wireless signals can be received by the lamp, in particular by the sensor unit.

Preferably, the user interface device is a remote control. The user interface device is not limited to a specific user interface device and can therefore be configured in any manner known to a person skilled in the art. Optionally, the user interface device may be a mobile device (may also be referred to as a mobile terminal) configured to emit optical radiation for transmission of wireless signals. Examples of mobile devices are mobile phones, notebooks, laptops, tablets, etc.

Preferably, the mounting unit is configured to mount the user interface device within the lamp or on the surface of the lamp. The user interface device may be integrated into the light fixture through the mounting unit.

In other words, the attachment unit is set up to attach the user interface device on the inside or the outside of the surface. In particular, the fastening unit is set up to fasten the user interface device on the inside of the lamp or inside the lamp in such a way that the user interface device can be operated by a user. Consequently, the user can issue commands to control the light output, such as a turn on command, off command, dimming command, etc. entered into the user interface device. For example, such an input may be possible via an actuation of one or more buttons and/or one or more switches of the user interface device. Alternatively or additionally, such an input can be possible via an optional touch-sensitive display unit (touch display) of the user interface device.

The fastening unit is preferably arranged inside the lamp and/or on the surface of the lamp. This means that the fastening unit can be arranged on the inside and/or on the outside of the lamp. The fastening unit can be integrated in the lamp.

According to one embodiment, the attachment unit is set up to detachably attach the user interface device to the lamp. This has the advantage that the user interface device can be used both as a local control element on the luminaire for controlling the light output of the luminaire when the user interface device is releasably attached to the luminaire by the attachment unit, and as a remote control for controlling the light output of the luminaire from a distance (within the range of optical radiation that can be emitted by the user interface device). For example, the attachment unit may releasably attach the user interface device to the light fixture using magnetism. The attachment unit can also be set up in another manner known to those skilled in the art to detachably attach the user interface device to the lamp. In addition to the benefit of being able to use a unified control unit to operate the light, the dedicated storage location also reduces accidental misplacement of the user interface device. Especially in the case of several user interface devices of the same type, this also reduces the risk of confusion.

According to a further embodiment, the lamp further comprises an optical unit, wherein the optical unit is set up to direct the optical radiation that can be emitted by the user interface device to the sensor unit; and the at least one optical sensor of the sensor unit is set up to detect the guided optical radiation. The optical unit is preferably set up to direct the optical radiation that can be emitted by the user interface device to the sensor unit when the user interface device is attached to the luminaire by the attachment unit.

This embodiment allows flexible positioning or arrangement of the fastening unit on the lamp, regardless of the arrangement of the sensor unit on the lamp, since the optical unit ensures that optical radiation emitted by the user interface device reaches the detection range of the at least one optical sensor and consequently through the at least one optical one Sensor is detectable when the user interface device is attached to the lamp by the attachment unit.

The terms "lead" and "guide" can be used synonymously for the term "steer".

In particular, the optical unit is set up to direct or guide the optical radiation that can be emitted by the user interface device to the at least one optical sensor (i.e. to the one optical sensor or to the multiple optical sensors) of the sensor unit.

In other words, the optional optical unit is set up to couple in the optical radiation emitted by the user interface device at a first position of the lamp at which the user interface device emits or outputs the optical radiation when the user interface device is attached to the lamp by the fastening unit . The term "to take up" can be used synonymously with the term "to couple in". Furthermore, the optical unit is preferably set up to direct or guide the coupled-in optical radiation to a second position of the lamp, at which the at least one optical sensor can detect the guided or guided optical radiation. That is, the second position is within the detection range of the at least one optical sensor. Furthermore, the optical unit is preferably set up to couple out the guided optical radiation at the second position, so that the optical radiation coupled out is detected by the at least one optical sensor. The term "output" can be used synonymously with the term "decouple".

The optical unit is thus set up to provide an optical path between the emission area of optical radiation of the user interface device when it is attached to the luminaire by the attachment unit, and the detection area of optical radiation of the at least one optical sensor. The optical radiation emitted by the user interface device is transmitted or directed to the detection area of the at least one optical sensor along this optical path when the user interface device is attached to the luminaire by the attachment unit. This ensures that radiation emitted by the user interface device (when the user interface device is attached to the lamp by the attachment unit) is detected by the at least one optical sensor.

The optical unit is preferably arranged inside the lamp and/or on the surface of the lamp. In other words, the optical unit can be arranged on the inside and/or on the outside of the lamp. The optical unit can be integrated in the lamp.

An arrangement within or on the inside of the lamp has the advantage that the deflection or guidance of the optical radiation by the optical unit cannot be disturbed by external factors, such as being shielded by a part of a user's body. The optical unit is preferably arranged inside the lamp in such a way that the optical path provided by the optical unit is arranged inside the lamp protected from external influences. In this case, the optical unit is preferably set up to decouple the guided optical light in the detection range of the at least one optical sensor of the sensor unit of the lamp to the outside of the lamp.

The optical unit preferably comprises a lens or a plurality of lenses, a reflector or a plurality of reflectors, a prism or a plurality of prisms, a light guide or a plurality of light guides, and/or a scattering element or a plurality of scattering elements.

In the present disclosure, as already used above, a first position of the luminaire corresponds to a position on the luminaire that is within the emission range (of optical radiation) of the user interface device when the user interface device is attached to the luminaire by the attachment unit. Furthermore, a second position corresponds to a position on the lamp that lies within the detection range of the at least one optical sensor of the sensor unit of the lamp. Consequently, the optical unit is arranged between the first position and the second position with respect to the optical path from the user interface device.

Preferably, the optical unit comprises a light guide, which is arranged between the first position of the lamp and the second position of the lamp, and a convex lens, which is arranged at the end of the light guide facing the second position. The light guide is set up to couple in optical radiation at the first position, to direct or guide the coupled-in optical radiation to the second position and to couple out at the second position. The convex lens is arranged to be at the second position to guide optical radiation that is coupled out to the at least one optical sensor, in particular to guide it to the at least one optical sensor over a short distance in air.

Alternatively or additionally, the optical unit preferably comprises a prism which is arranged at the first position. The prism is set up to couple in optical radiation at the first position and to couple out optical radiation via its convex side in the direction of the second position, i.e. in the direction of the at least one optical sensor. The convex side of the prism serves as a converging lens, which focuses the optical radiation in the direction of the second position and consequently in the direction of the at least one optical sensor.

Alternatively or additionally, the optical unit preferably comprises a reflector which is arranged at the first position. The reflector is positioned, shaped, and directed to direct optical radiation from the first position to the second position. Optionally, the optical unit can additionally include a lens for bundling the optical radiation in the direction of the second position.

Alternatively or additionally, the optical unit preferably includes a scattering element. The scattering element is set up to fan out optical radiation in such a way that a minimum amount of the optical radiation arrives at the second position and can consequently be detected by the at least one optical sensor. The scattering element is preferably a scattering film.

Alternatively or additionally, the optical unit preferably comprises an asymmetric lens arranged at the second position. The asymmetrical lens is preferably arranged on the sensor unit, in particular on the at least one optical sensor. The asymmetrical lens is designed in such a way that the at least one optical sensor is set up to detect optical radiation from the area surrounding the lamp, with the optical radiation preferably being detected in the direction of the first position of the lamp. This means that optical radiation is preferably detected in the direction of the user interface device when this is attached to the luminaire by the attachment unit.

Alternatively or additionally, the optical unit preferably comprises a scattering element, preferably in the form of a scattering film, which is arranged at the second position. The scattering element is set up to expand the detection range of the at least one optical sensor in such a way that optical radiation from the direction of the first position (and consequently optical radiation emitted by the user interface device) can be detected by the at least one optical sensor.

The optical unit is preferably set up to transmit optical radiation, which can be emitted by the user interface device, through the interior of the lamp to the at least one to steer optical sensor of the sensor unit of the lamp. The optical unit can preferably be set up to direct the optical radiation that can be emitted by the user interface device over an air gap.

Furthermore, the optical unit is preferably set up to increase the detection range of the at least one optical sensor of the sensor unit for detecting optical radiation. Additionally or alternatively, the optical unit is preferably set up to increase the emission range of the user interface device, which can be attached by the attachment unit, for the emission of optical radiation.

According to one embodiment, the lamp is a floor lamp, the fastening unit being arranged inside or on the surface of a floor section of the floor lamp. The fastening unit can be integrated in the standing section. The optical unit is preferably arranged inside and/or on the surface of the stand section. The optical unit can be integrated in the stand section.

The above statements regarding a floor lamp are correspondingly applicable.

The sensor unit with the at least one optical sensor is preferably arranged on the illuminant section. In particular, the sensor unit can be arranged inside or on the surface of the illuminant section. The sensor unit can be integrated in the illuminant section.

The optical unit is preferably set up to direct optical radiation from the first position of the floor lamp, which can be located at the base section of the floor lamp, to the second position of the floor lamp, which can be located at the illuminant section of the floor lamp.

According to one embodiment, the at least one optical sensor of the sensor unit is an infrared sensor configured to detect infrared radiation, and the user interface device is configured to emit infrared radiation. In other words, the optical radiation is preferably infrared radiation.

The lamp preferably comprises a bus and a control unit for controlling the light output of the lamp, the sensor unit and the control unit being electrically connected to the bus and the control unit being set up to control the light output of the lamp depending on the detection result of the sensor unit.

The sensor unit is thus preferably set up to communicate its detection results to the control unit via the bus. Detection results from the at least one optical sensor are also detection results from the sensor unit.

This is advantageous because a signal received from the sensor unit via the bus, which reflects a detection result of the at least one optical sensor, does not differ from a signal that would be output by a button module if a button was connected to the bus via the button module is. This is particularly the case when the bus is a DALI-2 bus and consequently communication via the bus is in accordance with the DALI-2 industry standard.

Consequently, for the control unit there is no difference between a signal received via the bus reflecting detection by the at least one optical sensor of optical radiation emitted by the user interface device in response to user input at the user interface device for controlling the light output of the luminaire; and a signal received via the bus that would be output by a button module when a button connected to the bus via the button module was actuated by a user to control the light output of the lamp.

The bus is in particular a wired bus. The bus is in particular an internal bus of the lamp. The control unit is preferably a processor, a microprocessor, a controller, a microcontroller, a field programmable gate array (FPGA), an application specific integrated circuit (ASIC) or a combination of these elements.

The control unit is preferably a DALI control unit and the bus is preferably a DALI bus. In this case, the sensor unit is a DALI sensor unit that is set up to communicate its detection results via the DALI bus in accordance with the DALI industry standard. Alternatively, the control unit is preferably a DALI-2 control unit, in particular a DALI-2 application controller, and the bus is preferably a DALI-2 bus. In this case, the sensor unit is a DALI-2 sensor unit that is set up to communicate its detection results via the DALI bus according to the DALI-2 industry standard.

The control unit is preferably set up to control the light output of the lamp via the bus. In order to emit light, the lamp can comprise at least one lamp module with one lamp or a plurality of lamps. Such lighting means are preferably light-emitting diodes (LEDs), so that the at least one lighting module is preferably a light-emitting diode module (LED module). The lamp preferably comprises at least one driver module for operating or supplying electricity to the at least one lamp module. If the at least one light source module is an LED module, the driver module can also be referred to as an “LED driver”. The terms "driver module", "driver circuit" and "operating device" can be used synonymously. The at least one driver module preferably includes at least one DC voltage converter (also known as a DC/DC converter referred to), which is set up to convert a first voltage into a higher or lower voltage (depending on the converter type). The at least one DC converter is preferably an actively clocked DC converter or switching regulator. The at least one driver module is connected to the bus and the control unit is preferably set up to control the driver module via the bus and thereby to control the electrical energy provided by the driver module to the at least one illuminant module. As a result, the control unit is set up to control the light emission of the at least one lamp module, which is dependent on the electrical energy supplied to the lamp module, and thus the light output of the lamp.

The control unit is thus preferably set up to control the light emission of at least one lamp module with at least one lamp via the bus, which can be arranged (i.e. can be arranged) in the lamp for the light emission of the lamp. In this case, the at least one lighting module can preferably be supplied electrically via a driver module, which can be connected to the bus and controlled by the control unit. Thus, the at least one driver module can be provided in the lamp for the electrical supply of the at least one lamp module.

The lamp is preferably set up to charge a rechargeable electrical energy store of the user interface device when the user interface device is attached to the lamp by the fastening unit. Alternatively or additionally, the lamp is preferably set up to increase its own light output for a period of time above a standby lighting level if the state of charge of the rechargeable electrical energy store falls below a limit value.

The increase above the standby lighting level allows the rechargeable electrical energy store to be charged with electrical energy using a photovoltaic unit of the user interface device if the light energy of the light output of the lamp at the standby lighting level is not sufficient for such a charging process and the light output must therefore be increased. Preferably, if the sensor unit is set up to detect the presence and/or movement of a person and/or an object and the luminaire is intended to increase the light output in the event of such a detection, the luminaire can be set up to, in the event of no such detection (absence and no movement of a person/object) to emit light at the standby lighting level. In such a case, the standby lighting level can also be referred to as the away lighting level. The brightness of the light emitted by the lamp increases as the light output of the lamp is increased.

In order to achieve the lamp according to the invention, the above optional features and embodiments can also be advantageously combined with one another.
