Method for operating a light fixture

Abstract

A method for operating a luminaire (1), in particular a table lamp (1) or floor lamp, is described. The luminaire (1) has a lamp frame (10) and a lamp head (20) arranged in an upper region of the lamp frame (10). Light is generated by a light source arrangement (30) arranged in the lamp head (20) and emitted in a direction of radiation (AR) into an illumination area (AB). A detection device (40) arranged in the lamp head (20) detects the movement of an object (H) in a detection area (DB), and the light source arrangement (30) is controlled by a control device (50) depending on the object movement detected by the detection device (40).When movement of an object (H) in a direction of movement (B2R) from a front of the detection area away from the luminaire frame (10) towards the luminaire frame (10) is detected, the light source arrangement (30) is switched on in a standby operating state of the luminaire (1) and switched off in a lit operating state of the luminaire (1). A corresponding luminaire (1) is further described.

Description

The invention relates to a method for operating a luminaire and a luminaire.Lamps, in particular table lamps and parking lights, are predominantly operated with the aid of manually operable switches, pushbuttons, control panels (e.g. touchpads) or the like. Especially for reasons of hygiene, there are more and more lights on the market that can be controlled in contactless fashion by gestures of the user. For control in a detection area, the user must then usually perform a certain gesture close to the luminaire, for example laterally on a frame of the luminaire, above, below or laterally of a luminaire head or the like with the hand. Depending on the gesture, it can then, for example, switch the luminaire on or off or dim the luminaire, i.e. adjust its brightness.A fundamental problem with such gesture control is that the user must know exactly which gestures he must perform in order to achieve a specific effect. In conventional lamps with switches, buttons, control panels or other visible user interfaces, these are generally provided with symbols, so that the user normally understands how to operate the lamp.In a gesture-controlled luminaire, the user generally needs to know the operation instruction, for the lack of such visible explanations at the user interface. However, this is not always guaranteed, for example when a luminaire is used by several users who have not obtained themselves, such as for example in luminaires in hotels, in offices with changing workstations, etc., wherein contactless control would be particularly attractive especially in these environments for hygiene reasons.A first problem often occurs when the light is switched on. If the user does not have precise knowledge about the operation, several tests may be necessary until the user has only switched on the light at all. Depending on the type of gesture to be carried out, there is also the risk that the user unintentionally switches the light off again immediately.This problem can lead to a frustrating user experience, which is neither in the interest of the manufacturer nor of an adjuster of the luminaire, for example the hotelizer or the employer who wishes to use these contactless luminaires in the office.It is an object of the present invention to provide a method for operating a luminaire and a luminaire with which the user-friendliness can be increased, in particular with respect to the above-mentioned problem.This object is achieved by a method according to claim 1 and a luminaire according to claim 12.The method according to the invention serves for operating a luminaire, in particular a table luminaire or a stand luminaire, which has a preferably adjustable luminaire frame and a luminaire head arranged in an upper region of the luminaire frame on the latter, preferably movably. The lamp head can preferably be detachably, but also fixedly, coupled to the lamp frame.The luminaire frame can preferably have a luminaire base, e.g. a luminaire foot, a table clamp or the like, and an arm which is coupled thereto, preferably in an articulated manner (e.g. pivotable and / or rotatable), and to which the luminaire head is in turn coupled, preferably likewise in an articulated manner (e.g. also pivotable and / or rotatable), to an end remote from the luminaire base. The arm can preferably also be multi-part, e.g. have a plurality of links which can in turn be connected to one another in an articulated manner. Examples of a preferred construction will be given later.In a method according to the invention for operating a luminaire, light is generated by means of a lighting means arrangement arranged in a luminaire housing of the luminaire head and is emitted in an emission direction through a light outlet opening in the luminaire housing into an illumination region. By means of a detection device, preferably likewise arranged in the luminaire housing of the luminaire head, a movement of an object in a detection region in front of the light exit opening is detected, and by means of a control device, the lighting means arrangement is controlled as a function of an object movement detected by the detection device.The lighting means arrangement can have one or more lighting means (i.e. a light-emitting element). The lighting means or light-emitting elements are preferably in each case LEDs. However, these may also be other elements, such as semiconductor lasers, OLEDs, etc. As will be explained later, the lighting means may preferably also be assigned to lighting means groups in order to be controlled in groups. Particularly preferably, the lighting means arrangement has lighting means, in particular LEDs, of different color temperatures. With a plurality of illuminants having different color temperatures and with a suitable controller (wherein e.g. a plurality of illuminants having the same color temperature can be controlled as one illuminant groups), it is possible to change the color temperature of the total light by mixing the light components of the different illuminants.The "illumination area" is an area that is illuminated by the light emitted by the light outlet opening in a sufficiently recognizable manner for the user. As a rule, this is a light beam in the manner of a light cone or the like, which expands with increasing distance from the light outlet opening. The "emission direction" (or "main emission direction") is considered to be the direction in which the predominant part of the light is emitted from the light exit opening on average, that is to say a type of central direction in which the luminous appearance runs. As a rule, the illumination area is located (in the usual position of use of a table light or a stand light) under the light head in front of the light frame, i.e. the light outlet opening of the light housing points downwards.It is noted here that orientation references such as "bottom" and "top" are used here as would be given in the above-described conventional position for a table light. The underside of the lamp head is thus the side at which the light outlet opening is located. The terms such as "front" and "rear" are to be understood to mean that the front side of a luminaire is the side which points toward the user in the usual use of a table luminaire, that is to say that the front side of the luminaire head is the side which is farther from the luminaire frame. The rear side (rear) of the luminaire is accordingly the side facing away from the user in the usual use, i.e. that the rear side of the luminaire head is the side on which the luminaire frame is located. "Right" and "left" are to be understood in each case from the perspective of a user located in front of the luminaire.The detection device has a sensor arrangement with at least one sensor and can therefore also be referred to as a sensor device. The sensor is preferably an image sensor, particularly preferably a C-MOS sensor (C-MOS=complementary metal oxide semiconductor) or more precisely an active pixel sensor (APS). An alternatively usable image sensor would be a CCD sensor (CCD=charge-coupled device). In principle, however, the sensor arrangement can also comprise a plurality of sensors, for example a sensor array, wherein the sensors could also again be image sensors. The detection area (which can also be referred to as "sensing area") is the spatial area in which the detection device can detect or detect objects, i.e. the "viewing area" of the detection device. The object to be detected can be any object, but in particular the hand of an operator of the luminaire.The luminaire also has a control device for controlling the lighting means arrangement as a function of an object movement detected by the detection device. The control device can be connected, for example, to the detection device by signal technology, and the detection device can output a detection signal to the control device, which then ensures suitable control signals to the lighting means arrangement. In this case, the evaluation of a movement and / or a position of the object in the detection region, in particular also of a distance of the object from the light exit opening, can take place in the detection device and / or in the control device. Depending on the configuration, the detection device and / or the control device can have corresponding, optionally also cooperating, evaluation units, which can also comprise a microcontroller, for example, or a corresponding evaluation functionality can also be realized in the control device in a (programmable) microcontroller or the like, which also ensures the appropriate control signals for the lighting means arrangement, for example, by appropriately controlling the supply voltage and / or the current for the lighting means in accordance with control commands of the microcontroller. In particular, the detection device and / or the control device can also be realized in the form of a common detection and control device.In the method according to the invention, the specific control for switching on the luminaire and for switching off the luminaire is carried out in such a way that a check is carried out as to whether a movement of an object in a direction of movement from a front side of the detection region remote from the luminaire frame to a rear side of the detection region lying in the region of the luminaire frame is detected in the detection region. If such an object movement is detected in the detection area, the invention providesin a standby operating state of the luminaire, i.e. in a state in which the detection device, the control device and the lighting means arrangement are supplied with energy, but in which the lighting means arrangement is switched off, the lighting means arrangement is switched on,andin a lighting operating state of the luminaire, in which the lighting means arrangement is switched on, the lighting means arrangement is switched off.Since the detection region is located in front of the light outlet opening on the underside of the luminaire housing, this means, in a usual position of use of the luminaire as described above, that the user moves a hand or another object substantially along an axis of movement running transversely to the emission direction into the space under the luminaire head in the direction of the luminaire frame, e.g. the luminaire arm. If the lamp head has been rotated sideways or upward by the user, the detection region is naturally also located laterally of the lamp head or even upward. However, in these cases as well, the movement of the object must take place from the front side of the detection area, i.e. from the front side of the lamp head to a rear side of the detection area lying in the area of the lamp frame, even if the movement is no longer directed directly against the lamp frame, but rather extends into an area next to or above the lamp frame.The use of this movement axis for a gesture for switching on or switching off is particularly intuitive, since in a plurality of conventional lamps a user interface with switches, buttons or the like is located in the area of the lamp frame, for example on the lamp base or on the lamp arm. The sensors for gestures are often also located in this area. Therefore, even a user who does not know the operation manual of the lamp will be more likely to move his hand instinctively into the area under the lamp head onto the lamp stand, and then he would immediately turn on the lamp.However, during a hand movement along this movement axis, which takes place in the direction of the luminaire frame or luminaire arm, the user instinctively also retracts the hand again in the opposite direction. In this case, the user would unintentionally switch the lamp off immediately again, which could make the user unsafe. A relatively complicated gesture, which would require, for example, the user to move his hand from the front against the luminaire frame and then to move it away laterally again, would not be particularly intuitive.The same problem would also occur when using the movement axis for setting another control parameter with opposite setting directions (such as light / dark, etc.). This is all the more so that in many cases the user would like to adjust the corresponding control parameter more precisely with such control parameters and it is therefore not unlikely that he would like to change in the reverse direction again immediately.Since as a rule no immediate switching on and off again is desired, however, this movement axis can be used particularly intuitively and simply as a function of the current operating state by the intentional "non-use" (e.g. deactivation) of the movement direction away from the luminaire arm and by double assignment of the movement direction towards the luminaire arm with the switching-on function and the switching-off function.A luminaire according to the invention has a luminaire frame and a luminaire head arranged in an upper region of the luminaire frame on the latter. The light is preferably a table light, particularly preferably a desk light, or a stand light. The lamp head has a lamp housing with a light outlet opening. A lighting means arrangement is arranged in the luminaire housing for generating light in order to emit it in an emission direction through the light outlet opening into an illumination region. The luminaire additionally has a detection device, preferably arranged in the luminaire housing, for detecting a movement of an object in a detection region in front of the light outlet opening and a control device for controlling the lighting means arrangement as a function of an object movement detected by the detection device. The detection device and / or the control device are configured such that when a movement of an object in the detection area is detected in a movement direction from a front side of the detection area remote from the luminaire frame to a rear side of the detection area lying in the area of the luminaire frame,the lighting means arrangement is switched on in a standby operating state of the luminaire,andthe lighting means arrangement is switched off in a lighting operating state of the luminaire.Further, particularly advantageous embodiments and developments of the invention are evident from the dependent claims and the following description, wherein the claims of one claim category can also be developed analogously to the claims and description parts to another claim category and in particular individual features of different exemplary embodiments or variants can also be combined to new exemplary embodiments or variants, even if the respective combination is not explicitly mentioned.In principle, there are various possibilities for embodying the lamp head, in particular the lamp housing with the light outlet opening and the illuminant arrangement located in the lamp housing.For example, in addition to the lighting means arrangement, the detection device can preferably also be accommodated in the luminaire housing and the luminaire housing can have a detection window. Preferably, the detection window is covered with a detection window cover, and the detection device is arranged in the luminaire housing behind the detection window cover. The detection region is then located in front of the detection window, that is to say outside the luminaire housing. The detection device is protected from intervention by the detection window. Depending on the type of detection device, this detection window can also be made opaque, so that the user cannot see the detection device or other components of the electronics. For example, as will be explained below, if the detection device operates with infrared radiation, it is sufficient if the detection window cover is transmissive for the relevant infrared radiationSimilarly, the light exit opening is preferably also covered with a light-transmissive pane. This can be clear, but is preferably diffuse, so that the light of the lighting means is mixed uniformly and the user does not see the lighting means arrangement directly.As will be explained further below, depending on a detected object movement, the lighting means arrangement can preferably be controlled depending on an object movement detected by the detection device in different function modes which serve for setting different control parameters (i.e. a control device of the luminaire is preferably designed in this way, for example). A function mode can relate, for example, to switching the luminaire on and off, another to a brightness setting and another in turn to a setting of the color temperature (or color).Preferably, for all function modes, the detection area lies substantially in the illumination area. That is to say that the luminaire device or its control device, detection device and light outlet opening in the luminaire housing are correspondingly designed such that the detection region lies substantially in the illumination region. Depending on the further configuration of the controller, this likewise enables particularly intuitive operation, for example by direct feedback of the settings, as will be explained specifically below with reference to examples. Unlike in the case of other luminaires, no control options by gestures outside the illumination region are then required here. In this embodiment, the positive effect can thus be used in each functional mode.In a particularly preferred embodiment, the lamp device, the light outlet opening and the detection device can be designed and arranged in the lamp housing with respect to one another such that the light outlet opening encloses the detection region in a plane transverse, preferably perpendicular, to the emission direction in a substantially ring-shaped manner. Here, "substantially annular" means that the light exit opening extends along a round or otherwise shaped ring as far as possible, around at least 270°, preferably at least 215°, particularly preferably completely annularly around the detection region (in this plane). The detection region thus runs substantially concentrically with respect to the illumination region and is located in particular close to the luminaire housing within the illumination region. In a particularly preferred embodiment, the detection region lies completely in the illumination region, preferably in a light cone.For this purpose, the luminaire housing can preferably be constructed such that the light outlet opening surrounds the detection window in a substantially ring-shaped manner. The detection window with the detection window cover can preferably be surrounded in the shape of a circular disk and substantially, preferably completely, all around by the light outlet opening. The light outlet opening can then be covered accordingly by a light-transmissive annular disc.As mentioned, in a preferred embodiment, the lighting means arrangement has at least two separately controllable groups of lighting means (referred to below as "lighting means groups"), wherein the lighting means groups (more precisely the lighting means of the lighting means groups) emit light of different color temperatures. It is particularly preferred that one group of lighting means is warm white lighting means, in particular LEDs, and the other group of lighting means is cold white lighting means, in particular LEDs.Since the brightness of the different light-emitting means groups can be adjusted separately, the color temperature of the total light can be adjusted to any value between the color temperature of the one light-emitting means groups and the color temperature of the other light-emitting means groups by mixing the light components of the different light-emitting means groups. This is a very simple possibility for adjusting the color temperature of the luminaire.The lighting means arrangement can preferably have at least one lighting means ring which comprises a multiplicity of lighting means arranged next to one another in a ring-like manner, wherein this lighting means ring runs around the detection device arranged in a central region in the lighting head. Preferably, it is a closed, substantially uninterrupted rim. If, however, the lighting means arrangement is to extend around the detection device only in a pitch circle, it would of course be sufficient if the ring extends only over this pitch circle.Particularly preferably, the lighting means arrangement has at least two or more such lighting means rims with different diameters, i.e. at least one inner lighting means rim and one outer lighting means rim. In other words, the lighting means are arranged in a plurality of rings around the central detection device. Preferably, all lighting means rims are closed when the lighting means arrangement is to extend in a complete circle around the detection device.Most preferably, each lighting means ring has lighting means of two lighting means groups, particularly preferably in alternating rows. That is to say that there are always, for example, alternately next to one another, in the ring or rings a lighting means with a first color temperature, then a lighting means with a second color temperature, then again a lighting means with the first color temperature, etc. It is thus deliberately ensured that not all lighting means of a lighting means ring belong to a lighting means group, so that the lighting means of the lighting means groups are arranged spatially distributed as well as possible within the lighting means arrangement, in order to achieve uniform mixing of the light with the different color temperatures.In order to effectively use the light of the lighting means, a reflector is used which runs substantially annularly, preferably annularly closedly, around the detection device arranged in a central region in the lamp head. The lighting means arrangement, i.e. for example the lighting means rims, is arranged in this reflector.The reflector and the lamp ring or the lamp rings located therein are preferably located directly behind the light outlet opening or the ring-shaped light-transmissive pane in the lamp housing. The reflector is designed to widen conically in radial cross section towards the light outlet opening.A particularly effective use of the detection region, in particular of a limited detection region within an illumination region, which additionally allows a clear delimitation and thus easy recognition of the gestures, is achieved, for example, by the different functional modes preferably being assigned to different movement axes (e.g. right / left, forward / backward, up / down) of the object by the detection region or in the detection region.In this case, at least in some of the movement axes, a specific setting direction of the control parameter (for example stronger / weaker) is preferably assigned to a movement direction of the object along a movement axis.Preferably, in this case, exactly one function mode is assigned to different, particularly preferably three, movement axes that are essentially orthogonal to one another.The term "orthogonal" movement axes is to be understood in this case such that the user does not necessarily have to carry out the movement exactly along the respective movement axis, but rather that the actual movement of the object can also take place on a largely arbitrary path as long as the detection device can unambiguously associate the object movement with a defined movement axis.For this purpose, the detection device can be preferably constructed, for example, such that it only registers at which point the object enters the detection region and at which point it exits again. This applies in particular to the directions of movement running parallel to the light beam exit opening.A possible example of a skillful realization of such a detection device will be explained later. Preferably, the detection region can be easily divided into quadrants, and depending on which quadrant the object enters the detection region and in which quadrant it exits again (preferably within a predefined maximum time), object movements in the various movement axes (and thus the presumably intended function modes addressed to the user) can be identified reliably and efficiently. Complex detection of the exact movement path or a speed profile or the like is then advantageously not necessary for this purpose.An object movement in the detection region along a movement direction running perpendicular to the plane of the light beam exit opening is possible, in particular if the detection is carried out by means of a detection device in the lamp head, preferably with a distance measurement. For this purpose, the detection device and / or the control device must be designed accordingly to detect the distance. Preferably, after the user has moved the object or the hand into the detection region, the initial position is first determined as the starting distance of the object from the light head and then, in the case of a continuous movement of the object along a movement axis running substantially perpendicular to the plane of the light outlet opening, the distance is measured regularly or permanently and the distance values are evaluated in a suitable form. Preferably, only the change in the distance during gesture is important, so that it is largely immaterial at which height the user starts the gesture. In this procedure, neither a specific movement path nor a speed profile or the like has to be determined.Very particularly preferably, when assigning function modes to the individual movement axes, a brightness setting (i.e. dimming, for example) can be assigned to a first movement axis which extends substantially perpendicular to the plane of the light exit opening (up / down). The assignment of the brightness setting to the up and down movement is particularly intuitive if the lighting means arrangement is dimmed, i.e. the brightness is reduced, when the object is lowered.According to the invention, a second movement axis which extends substantially perpendicular to the first movement direction (for example preferably forwards / backwards) is assigned the switching on and the switching off of the luminaire.A third movement axis (e.g. preferably right / left), which extends substantially perpendicular to the first movement direction and perpendicular to the second movement direction, can be assigned including an adjustment of the color temperature (e.g. cold white / warm white) of the lighting means arrangement.In this embodiment, the advantage of the procedure according to the invention when switching the luminaire on and off is particularly noticeable, and the other axes of movement can be assigned to the function modes in which, at a specific point in time during operation of the luminaire, both a movement in the one direction and in the opposite direction along the axis of movement is expedient in order to change or set a control parameter in one or the other direction.Preferably, in the case of movements at least along a movement axis, a value of a control parameter is increased by a defined step if a movement of an object along this movement axis is detected in a first movement direction, and a value of the same control parameter is decreased by a defined step if a movement of an object along the same movement axis is detected in a second movement direction opposite the first movement direction.Preferably, there are in each case a plurality of stages for the direction(s) of movement, particularly preferably at least three stages, further preferably at least four stages, further preferably at least five stages. This is preferably the case with the third movement axis defined above and / or for setting the color temperature.This idea of a stepwise adjustment of a control parameter value with each movement in a specific movement direction along a specific movement axis and a reverse stepwise adjustment with each movement direction back along this movement axis can be used advantageously not only in connection with the invention, but also in other luminaires or luminaire devices (for example also without a luminaire frame) in which a movement of an object is detected in a detection region and in which a lighting means arrangement of the luminaire or luminaire device is then controlled in dependence on a detected object movement. It can thus be seen and used as an independent idea.Alternatively or additionally, in the case of movements at least along a movement axis, a value of a control parameter is continuously increased if a movement of an object along this movement axis is detected in a first movement direction, and a value of the same control parameter is continuously decreased if a movement of an object along the same movement axis is detected in a second movement direction opposite the first movement direction. This is preferably the case with the first movement axis and / or for setting the light brightness.As already mentioned, infrared radiation is preferably used for detecting an object movement. For this purpose, an IR sensor arrangement (IR=irradio) with at least one IR sensor (preferably an IR-sensitive C-MOS sensor) can be used (for example as part of the detection device). The detection device can particularly preferably emit IR radiation and at least a part of the IR radiation reflected by an object located in the detection region can be detected by means of the IR sensor arrangement in order to detect a movement of the object. The use of infrared radiation has the advantage that disturbances due to ambient light can be reduced or even largely prevented.For this purpose, the detection device can have at least one IR transmitter which transmits in a wavelength range matching the IR sensor arrangement. The IR transmitter is designed such that IR radiation (e.g. through the detection window) is emitted by the IR transmitter and at least a part of the IR radiation which is reflected by an object located in the detection region (e.g. back through the detection window) can be detected by means of the IR sensor arrangement.Any detection window covering is then accordingly IR-transmissive in the appropriate wavelength range, as mentioned. The wavelength range is preferably between 800 nm and 900 nm, particularly preferably in the range of 850 nm. The peak of the wavelength range of the IR radiation is indicated in each case, the width of the wavelength range depends on the IR transmitter used and can be negligible.Very particularly preferably, only in the case of a detected object movement in a region within a maximum distance from the light exit opening, a change of a control parameter of the lighting means arrangement takes place depending on the object movement (if the type of detected object movement is associated with a control parameter change at all).The maximum distance relates here to the direction perpendicular to the plane of the light outlet opening. It is preferably 40 cm, more preferably 35 cm, particularly preferably 30 cm.For this purpose, the detection device can be designed, for example, such that the movement of an object is detected only within this maximum distance in the detection area, i.e. the physical detection area is thus limited. Alternatively or additionally, the control device can also be designed such that, if a distance of the detected object (in the detection region) greater than this maximum distance is detected or detected, it correspondingly outputs no control commands to the lighting means arrangement. That is, the control device is correspondingly programmed in such a way that it ignores recognized gestures if they have not occurred within the maximum distance.The limitation of the "usable detection range" to a maximum distance has the advantage that a user does not exercise the light with any awareness by movements that were not intended at all for controlling the light. As mentioned, one of the preferred applications of the lighting device is the use as a lighting head of a table light. This usually serves to illuminate a table surface. Normally, the user works on this table, and it can often happen that he also reaches the area above the table surface in the light cone of the lamp head with his hand and carries out movements. These should not normally result in any control parameters of the luminaire being changed.A table light is namely generally, as mentioned above, placed with its light frame on a table surface and / or mounted thereon, e.g. clamped, in order to illuminate the table surface from above. Then, the lamp head can preferably be arranged in a position above the table surface by height adjustment on the lamp frame (for example by pivoting a lamp arm to which the lamp head is fastened on the top side) such that the detection region or the maximum distance ends at least 15 cm, preferably at least 20 cm, above the table surface.This concept of limiting the "usable detection range" is particularly advantageous in combination with the features according to the invention and the further features described, but can likewise be used advantageously not only in connection with the invention, but also in other luminaires or luminaire devices (for example also without a luminaire frame) in which a movement of an object is detected in a detection range and in which a lighting means arrangement of the luminaire or luminaire device is then controlled as a function of a detected object movement. It can therefore likewise be seen and used as an independent idea.As mentioned, the lighting means arrangement can be controlled in dependence on a detected object movement in different function modes which serve for setting different control parameters.In the case of luminaires with gesture control, in particular those with a plurality of function modes, the problem may possibly arise that the user (without knowledge of the precise operating instructions) cannot be sure whether the luminaire is currently in a specific function mode, i.e. which control parameters he could currently change.Certain operating modes are therefore preferably activated only when the lighting means arrangement is switched on. If, for example, as mentioned, a function mode relates to the switching on and switching off of the lighting means arrangement, then further function modes are particularly preferably activated only when the lighting means arrangement is switched on. In other words, it is therefore only possible to control further control parameters such as brightness or color temperature by gestures if at least sufficient light is emitted so that the operator can notice the changes directly.The user can thus determine, by directly changing the light as feedback to his gesture, that the light is currently in a specific setting mode, i.e. he directly receives the feedback about a set fire parameter. Other types of optical or acoustic signaling that the user can set something with gestures or which settings he makes can then be dispensed with. In addition, it is not possible for the user to adjust control parameters selected by him unintentionally (during the last use of the luminaire) when the luminaire is switched off, which would then not be noticed until the luminaire is switched on again.This concept of "deactivation" of certain function modes, preferably of all other function modes from a switched-on mode of the luminaire, is also particularly advantageous in combination with the features according to the invention and the further features described, but can likewise be used advantageously not only in connection with the invention, but also in other luminaires or luminaire devices (for example also without a luminaire frame) in which a movement of an object is detected in a detection region and in which a lighting means arrangement of the luminaire or luminaire device is then controlled as a function of a detected object movement. It can therefore likewise be seen and used as an independent idea.In addition to the lighting means arrangement, further (electrical and electronic) components required for operating the luminaire are preferably arranged in the luminaire housing of the luminaire head, and specifically particularly preferably at least all components except for a voltage supply.The voltage supply, on the other hand, can be relatively easily guided through the luminaire frame. The luminaire frame, preferably the luminaire base, can have a connector plug for a power source. In the preferred, simplest case, lines can then simply be looped through from a connector plug on the lamp base to the lamp head.The connector plug is preferably a standard plug, particularly preferably a USB-C type. The luminaire can thus be operated on a power supply unit, but also on the laptop, a power bank or the like, in particular if the electrical and electronic components in the luminaire device or in the luminaire head are designed to an operating voltage of 5V.In an advantageous development of this concept, the lamp head and the lamp frame can also have interacting energy supply plug connectors in order to connect the lamp head to the lamp frame (in particular an arm of the lamp frame) in a releasable manner. The lamp head can then be removed from the frame and, for example, plugged onto another frame.The power supply plug connector on the luminaire frame can be connected (directly or indirectly electrically) within the luminaire frame to a connector plug on the luminaire frame for a power source (similar to that described above) simply by suitable lines being looped through the frame from the connector plug to the power supply plug connector.The interacting power supply plug connectors on the lamp head and on the lamp frame can also be designed to be stronger on the lamp frame, as in the case of the supply, preferably in a USB standard, in particular a USB-C standard. The lamp head of the lamp would then also be operable independently of a lamp frame, for example directly via a USB cable.As mentioned above, a luminaire according to the invention can preferably have a luminaire base, e.g. a luminaire foot, a table clamp or the like, and an arm coupled thereto, preferably in an articulated manner (e.g. pivotable and / or rotatable), to which arm the luminaire head is in turn coupled, preferably likewise in an articulated manner (e.g. also pivotable and / or rotatable), to an end remote from the luminaire base. Preferably, the arm is multi-part and has, for example, a plurality of links which in turn can be connected to one another in an articulated manner.Particularly preferably, at least two links of the at least two-link (i.e. multi-link) arm, e.g. a lower link on or connected to the luminaire base and an upper link on the luminaire head, can be plugged together in a (middle, i.e. articulatedly connecting the two links) joint of the arm by means of a plug connection for operating the luminaire which conducts current during the intended operation of the luminaire head and can be pulled apart for transporting the luminaire.Such a luminaire is particularly advantageous since it can be disassembled or pulled apart into a significantly smaller packaging dimension for transport, or the links of the arm may not be first plugged together at the manufacturer, but rather this is only done on site for use, which saves transport, storage and packaging costs and packaging material. Therefore, this concept is also advantageous independently of the configuration according to the invention of the luminaire or of the method according to the invention for operating the luminaire and can in principle be used in any luminaire which has an at least two-link arm between the luminaire base and the luminaire head. It can therefore likewise be regarded as an independent idea, even if a combination with the method according to the invention or the luminaire produces a particular synergy effect.This applies in particular to such variants in which the luminaire is arranged with a lighting means arrangement arranged in a luminaire housing and further components required for operating the luminaire, preferably at least all components apart from a voltage supply if appropriate, are arranged in the luminaire housing. In this case, it is sufficient if the plug connection simply serves as a conductor for the power supply. No control commands, etc., then have to be transmitted via additional lines, which would in principle also be possible if the plug connection has sufficient contacts for this purpose. Here too, the method according to the invention for operating a luminaire or the controller according to the invention by detecting an object movement in the detection region is particularly advantageous since all control components can in principle be arranged in the luminaire head.The plug connection can preferably have at least two conductors, i.e. be two-pole, e.g. coaxial with an inner conductor and an outer conductor.The plug connection can preferably comprise a two- or multipolar, coaxial plug connector or plug (i.e. a so-called "jack plug"), for example a standard 2.5 mm 2-pole jack plug and a plug connector receptacle or socket formed in a fitting manner thereto (e.g. a so-called "jack socket"). Jack plugs are simple to handle, can be released quickly and are very space-saving. They are also proven and widely used and thus widely available.The pluggable or pull-apart joint is preferably constructed such that the plug axis or plug direction, in which the plug connection can be plugged together or pulled apart, runs transversely, particularly preferably perpendicularly, to the pivot axis about which the members connected via the joint can be pivoted relative to one another.Preferably, the links of the arm can be additionally secured in the joint in the plugged-together state by means of at least one threaded pin (with an inner shoulder), particularly preferably two such threaded pins. Threaded pins (with an inner shoulder), also referred to colloquially as "grub screws", have the advantage that they are completely countersunk in the component in the screwed-in state and thus do not protrude, which is both visually appealing and also enables a particularly compact joint.It should be pointed out at this point that it is also possible in principle for the interacting energy supply plug connectors on the luminaire head and on the luminaire frame to be designed as two-pole or multipolar coaxial plug connectors, so that the luminaire head is freely rotatable about its longitudinal axis with respect to the luminaire frame.In particular, since more and more people work in the so-called mobile office, there is a need for correspondingly mobile, i.e. easily transportable, lights which are required next to the laptop in order to illuminate the current work area. The table light, but also the stand light, is particularly well suited for this purpose. This applies in particular to the versions in which a multi-link arm of the luminaire, for example for transport and / or storage, can be pulled apart or disconnected or the corresponding parts are not yet stored and shipped plugged together by the manufacturer and distribution and can only be plugged together for use.The invention is explained in more detail below with reference to the attached figures on the basis of exemplary embodiments. In this case, identical components are provided with identical reference numerals in the different figures. The figures are generally not to scale. The following are shown: FIG. 1 is a perspective view of an embodiment of a table light according to the invention, obliquely from above, FIG. 2 shows an enlarged perspective illustration of the lamp head of the table lamp according to FIG. 1 obliquely from below, FIG. 3 shows a side view of the table light according to FIGS. 1 to 3 with a schematic illustration of the illumination region and of the detection region, FIG. 4 is a plan view of the table light according to FIGS. 1 to 3 with a schematic illustration of the illumination region and the detection region from above, FIG. 5 is a bottom view of the lamp housing of the lamp head of the table lamp according to FIGS. 1 to 4 with a schematic representation of components in the lamp head, FIGS. 6 to 8 each show a lateral view of the table light as in FIG. 3 with a schematic representation of the possible gestures for setting certain control parameters, FIG. 9 is a flow chart for explaining an embodiment of a control program for a luminaire according to the invention, FIG. 10 shows a lateral view of a further exemplary embodiment of a luminaire having an arm which can be plugged together in a joint comprising a lower link and an upper link, in this case having links which are angled with respect to one another FIG. 11 is another side view of the luminaire of FIG. 10, this time with the links in common alignment, arranged vertically upwards, FIG. 12 is an exploded view of the members of the luminaire of FIG. 10 in an exploded state, FIG. 13 is an enlarged side view of the joint of the luminaire according to FIG. 12 , FIG. 14 is an enlarged perspective view of the joint of the luminaire according to FIG. 12.FIGS. 1 to 8 show an exemplary embodiment of a table light 1 equipped according to the invention. As can be seen in FIG. 1, the table light 1 has a light head 20 which is arranged at an upper end of a light frame 10 with a hinged light arm 12 which is two-bar in this case.The light frame 10 here has a light foot 11 at a lower end for placing the table light 1 on a table top (not shown). This light base 11 consequently forms a light base 11 here. Alternatively, instead of a light base 11 for parking, a clamping element for clamping to a table top or another light base could also be used.A lower part or a lower link 12 uof a luminaire arm 12 extends vertically upwards from the luminaire base 11, wherein this lower link 12 uof the luminaire arm 12 is connected to the luminaire base 11 via a lower joint 13 u(a pivot joint) such that the lower link 12 u, and thus the entire luminaire arm 12, can be rotated through 360° on the luminaire base 11 in the rotational directions DR 1 in the clockwise and counterclockwise direction.At the upper end of the lower link 12u of the lamp arm 12, an upper link 12o of the lamp arm 12 is hinged via a central hinge 13m. This joint 13 mis designed such that the upper link 12 ocan be pivoted upward in a rotational direction DR 2 about a horizontal pivot axis running perpendicular to the longitudinal axis of the lower link 12 urelative to the lower link 12 uof the lamp arm 12 and can also be pivoted downward again in the opposite direction. The possible adjustment range of the pivot angle is preferably at least 90°-180°, i.e. at least from a horizontal position of the upper link 12 o(equal to 90° relative to the lower link 12 u) to a vertical position of the upper link 12 o(equal to 180° relative to the lower link 12 u). It is preferably a self-holding joint 13 m, i.e. the joint 13 mis formed such that the upper link 12 oof the luminaire arm 12 remains self-standing in any position.For example, in a table light (as shown in the figures), the lower member 12u may be substantially shorter than the upper member 12o, and in a stand light, this may be the opposite.The lower member 12 uand the upper member 12 oof the luminaire arm 12 can each be rod-shaped, each with (in the case of a customary placement of the luminaire; see the above definition of the directions) a front longitudinal edge or front edge 12uv, 12ovwhich points towards the user and a rear longitudinal edge or rear edge 12uh, 12ohwhich points away from the user. In a preferred variant, the lower member 12 uhas a slot 18 on an upper side facing the upper member 12 o. This may, for example, corner into adjacent areas of an upper face 17 and the trailing edge 12uh of the lower member 12u (e.g., as shown in Figure 1). A tab 19 disposed on the front edge 12ov of the upper member 12o can engage in this slot 18. This tab 19 has an eyelet through which a shaft extends in the slot 18 transversely of the slot 18 (perpendicular to the longitudinal extension of the lower link 12u) (this is not shown in the figures) to connect the upper link 12o to the lower link 12u as desired so as to be pivotable about the axis of rotation DR2. The tab 19 engages above a lower end section 15 uof the upper link 12 oso that in the pivoted-up state (180° position) of the upper link 12 o, its front edge 12ov abuts in the lower end section 15 uon the rear edge 12 uhof the lower link 12 u.Preferably, the rear edge 12 uhof the lower link 12 uand the front edge 12ovof the upper link 12 oare each configured to be flat, so that these edges 12 uh, 12ovare in flat contact with one another in the pivoted-up state of the upper link 12 o. If, in addition, the upper end face 17 of the lower link 12 u(apart from the slot 18) is also of flat design, the front edge 12ov of the upper link 12 opreferably bears flat on the upper end face 17 of the lower link 12 uin the downwardly pivoted state (90° position). The leading edge 12uv of the lower member 12u and the trailing edge 12uh of the upper member 12o may be rounded, on the other hand.At the upper end 15 oof the upper link 12 oof the lamp arm 12, the lamp head 20 is then fixed via a head joint 16. This head joint 16 is preferably designed in the manner of a ball joint, for example also a self-holding ball joint, and permits a rotation of the luminaire head 20 about two axes of rotation. In this case, the lamp head 20 can be tilted up and down arbitrarily in the rotational direction DR 3 in an angle range of 0° to 90° with respect to the angle between a lower side 20 uof the lamp head 20 and the front edge 12 oof the upper link 12 o), wherein 0° is the position in which the lamp head 20 and the upper link 12 oof the lamp arm 12 are aligned, and in the 90° position, the lamp head 20 and the upper link 12 oof the lamp arm 12 are mutually aligned. On the other hand, the lamp head 20 can be pivoted back and forth in the rotational direction DR 4 by + / - 95°, wherein the 0° position is the position in which the lower side 20 uof the lamp head 20 points downward. Alternatively, such a two- or multipolar coaxial plug connector can also be arranged in the head joint in order to rotate the lamp head at this location as desired about the plug connector axis or longitudinal axis of the plug connector or to decouple the lamp head.It is pointed out that such a table light 1 is merely a preferred exemplary embodiment of a light 1 designed according to the invention. In principle, the invention can also be used on other types of lamps, for example a self-supporting lamp. This can in particular also have a similar light head 20, as in the exemplary embodiment in the present figures, but another frame, which can in particular also have longer members, so that the light can be placed on the ground and then the light head can be arranged approximately at the head height of an adult person. In principle, however, completely different exemplary embodiments are also possible. In this respect, the lamp head illustrated in this preferred exemplary embodiment can be seen as a preferred configuration of a lamp device configured according to the invention.The luminaire frame 10 here has about 65 cm from the lower edge of the luminaire foot 11 to the end of the upper link 12 oof the luminaire arm 12 at the head joint 16 in the fully extended position of the luminaire arm 12.The lamp arm 12 or the individual links 12 u, 12 oof the lamp arm 12 and optionally the joints 13 m, 16 are designed such that at least one electrical line can be looped through from a connector plug 14 in the lower link 12 uof the lamp arm 12 (here on the rear side of the lamp arm 12 and therefore not visible in FIG. 1 ) as far as into the lamp head 20 in order to supply the electrical or electronic components in the lamp head 20, which will be explained later, with energy. The connector plug 14 is preferably located below the region of the rear edge 12 uh of the lower link 12 u, in which the front edge 12ov of the upper link 12 oabuts against the rear edge 12 uh of the lower link 12 uin the pivoted-up state of the upper link 12 o.The connector plug is particularly preferably a USB-C plug. As will also be explained later, the lamp device or lamp head 20 is designed such that it can be operated at 5 V. By using, for example, the USB-C plug or another suitably standardized plug, it is possible to connect the table light 1 to a commercially available 5V power supply unit, as is used, for example, for mobile terminals. Advantageously, it is also possible, for example, simply to connect the light to a power bank or the like via a USB cable in order to operate it in a mobile manner. Furthermore, a connection via a USB cable or the like to a corresponding connection of a laptop would be possible.Particularly preferably, therefore, the table light has a total weight of only 2.8 kg at the maximum, preferably 2.3 kg at the maximum, and is therefore relatively light.As mentioned, there is a need for mobile lights that can be used in the "mobile office" to illuminate the current working area. A table light of this type is particularly well suited for this purpose, but also the auxiliary light described further below, in particular if a multi-link arm of the light is constructed such that it can be plugged together in the joint and can only be plugged together in each case for use.As can also be seen in particular in FIGS. 1 to 4, the lamp head 20 here has a cylindrical lamp housing 21, which is shaped here like a relatively flat circular disk. The outer diameter d of the lamp housing 21 is about 11 cm and the height h is about 1.6 cm.Preferably, the ratio of height h to outer diameter d of the luminaire housing 21 is approximately 0.15.As can be seen clearly in FIG. 2, this luminaire housing 21 has a central, circular detection window 24 on an underside 20 u, around which a light outlet opening 22 is arranged in a ring shape. The annular light exit opening 22 is separated from the circular detection window 24 by a partition wall 27. The light outlet opening 22 is bounded towards the outside by a circumferential outer wall 26 (the cylinder jacket) of the luminaire housing 21.The light exit opening 22 is covered by an annular disk 23. This is a light-transmissive pane 23, preferably a diffuse glass or plastic plate (for example made of milk glass or a suitable similar plastic material), in order to conceal the illuminant arrangement 30 (see FIG. 5 ) located behind the pane 23 in or behind the light outlet opening 22 in the luminaire housing 21 and to achieve uniform mixing of the light of different illuminants 33, 34 (here LEDs) of the illuminant arrangement 30 into an illumination region AB (see FIGS. 3 and 4 in this respect). However, embodiments with a simple, non-diffuse, transparent glass or plastic plate for protecting the lighting means 33, 34 from undesired contact or without a glass or plastic plate are also possible in principle.The central detection window 24 is covered with a detection window cover 25, so that the detection device 40 or sensor device 40 located behind it is also not recognizable to the user. This detection window 24 is a material which is transparent to infrared radiation, since the detection device 40 operates with infrared radiation, as will be explained later. In this respect too, however, embodiments with a transparent glass or plastic plate, for example, for protecting the detection device 40 from undesired contact or without a glass or plastic plate are in principle also possible.The arrangement of the detection window 24 and the light outlet opening 22 in the luminaire housing 21 can be seen particularly well, as stated, in the enlarged illustration of the underside 20 uof the luminaire head 20 in FIG. 2. The width b of the annular light exit opening 22 in the radial direction is here approximately 2.5 mm and the diameter dd of the detection window 24 is approximately 3.6 mm.FIGS. 3 and 4 show schematically, on the one hand in section (FIG. 3 ) and, on the other hand from above (FIG. 4 ), the extent of the illumination region AB, in which the substantial part of the light of the lighting means arrangement 30 is emitted from the lamp head 20, and of the detection region DB. This detection area DB is the area in which the detection device 40 can detect the movement of an object H, generally the hand H of the user, i.e. it is the "visible area" of the detection device 40. As can be seen in FIGS. 3 and 4, the detection area DB is advantageously located substantially everywhere within the illumination area AB, so that the user recognizes where the detection area DB is located when the light 1 is switched on, i.e. when light is emitted. It merely has to pass through the light beam which is currently emitted by the luminaire 1 in order to achieve a corresponding reaction in the control of the luminaire 1.The emission angle α of the illumination region AB, i.e. the angle of the total light cone emitted by the annular light outlet opening 22, is here approximately 78°. Here, the emission angle α is considered to be the angle which extends from the one edge to the opposite edge of the light cone which is emitted overall by the luminaire head 20 (that is to say from the radial outer side of the light outlet opening), wherein the edges of the light cone are defined such that the light intensity is only 50% of the maximum emitted light intensity at these points. For the sake of better clarity, the edges of the light cone are only drawn in in FIG. 3 up to the height of the maximum distance a, in which the detection region DB ends, as will be explained later. The cone of light of course propagates further. The radii of the illumination area AB and of the detection area DB are matched approximately to the radii at the height of the maximum distance a in FIG. 3 in FIG. 4, in order to clearly illustrate the position of the detection area DB in the illumination area AB.FIG. 5 shows a view from below of the luminaire head 20 with the light outlet opening 22 opened and the detection window 24 opened, i.e. the pane 23 and the detection window cover 25 are removed here. As a result, the structure of the lighting means arrangement 30, the detection device 40 and the control device 50 are relatively easily visible.The lighting means arrangement 30 preferably has at least one outer lighting means ring 31 a(which has a multiplicity of lighting means 34, 35 arranged next to one another in a ring) and an inner lighting means ring 31 i(which likewise has a multiplicity of lighting means 34, 35 arranged next to one another in a ring). The outer diameter of the outer lamp ring 31 ais here approximately 8.3 mm and the inner diameter of the inner lamp ring 31 iis approximately 6 mm. Particularly preferably, however, the lighting means arrangement 30 can also have more than two lighting means rims, i.e. at least one middle lighting means rim can be arranged between an outer lighting means rim 31 aand an inner lighting means rim 31 i, or even a plurality of middle lighting means rims can be present. In particular in the case of the above-mentioned dimensions of the luminaire head 20, three lighting means rims are very particularly preferred. However, for the sake of better clarity, FIG. 5 only shows the outer lamp ring 31 aand the inner lamp ring 31 i.The lighting means 34, 35 in this exemplary embodiment are LEDs 34, 35. here there are two groups 32, 33 of lighting means 34, 35 (also referred to below as lighting means groups), namely on the one hand a first group 32 of first, here warm white, lighting means 34, in particular LEDs 34, and a second group 33 of second, here cold white, lighting means 35, in particular LEDs 35.The various light source groups 32, 33 can be controlled separately. That is to say, it is possible to actuate the first illuminant group 32 with one signal and the second illuminant group 33 with another, separate signal. Consequently, the two illuminant groups 32, 33 can be controlled separately with respect to their intensity, such that the total light emitted overall by the illuminant arrangement 30 can be varied both in terms of brightness and in terms of color temperature, as is explained later.In order to achieve the best possible mixing, the lighting means 34, 35 of the various groups 32, 33 are distributed over the various lighting means rims 31 a, 31 i, namely a warm-white lighting means 34, then next to this a cold-white lighting means 35, then again a warm-white lighting means 34, etc. In addition, the light outlet opening 22, as already explained above, is preferably covered with a diffuse pane 23. The individual lighting means 34, 35 are then not visible to the user, but instead simply sees the color temperature of the mixed total light.The color temperature of the mixed total light can be adjusted in this way between 2700 K (corresponding to the color temperature of the warm white LEDs 34) and 6500 K (corresponding to the color temperature of the cold white LEDs 35), since in the extreme case either one or the other group of lighting means 32, 33 can be turned off.In order to concentrate the emitted light more strongly on the light outlet opening 22, the lighting means rims 31 a, 31 iof 34, 35 are arranged in a suitably shaped reflector 36 which correspondingly extends annularly in the lighting device housing 21 behind the light outlet opening 22. In radial cross section, this reflector 36 is designed to widen chronically in the manner of a funnel starting from the lighting means rims 31 a, 31 itoward the light outlet opening 22. The reflector 36 can preferably have a white, preferably hard white, or mirror-like, silver surface on the inside in order to improve the reflection.As already explained above, the light outlet opening 22 is bounded radially inward by a separating wall 27. The detection device 40 is located here within the central region annularly surrounded by this dividing wall 27. the detection device 40 comprises here an IR sensor arrangement 41 in the form of a C-MOS sensor 41 (more precisely an active pixel sensor (APS); active pixel sensor) which detects infrared light having a wavelength in the region of 850 nm and can capture images in this region (the sensor arrangement 42 can also be referred to for short as IR sensor 41). In addition, the detection device 40 has an IR transmitter 42 which emits light in this wavelength range. Both components 41, 42 are accommodated on a printed circuit board on which the complete control device 50 with a microcontroller 51 and further electrical components 52 required for operating the control device 50, the detection device 40 and the lighting means arrangement 30 is also accommodated. Of these, only a few electrical components 52 are shown symbolically in FIG. 5. The detection device 40 and the control device 50 for controlling the lighting means arrangement 30 thus form a common unit with a programmable microcontroller 51.The detection device 40 operates in principle such that infrared light is emitted into the detection region DB by the IR transmitter 42 through the detection window 24. As soon as an object H reaches the detection region DB, the infrared light is reflected by this object H and in part reaches the sensor arrangement 41, i.e. the C-MOS sensor 41, which thus detects the position, e.g. as a type of coarse image, of the object H. The image data of the C-MOS sensor 41 can then be evaluated by the microcontroller 51 and the desired signals are output to the lighting means arrangement 30 in accordance with the predetermined programming. In a particularly preferred, simple variant, two pulse-width-modulated control signals are simply generated for the different light-emitting means groups 32, 33, wherein the intensity of the light of the light-emitting means 34, 35 of the respective light-emitting means group 32, 33 is determined by the pulse width. These simple means make it possible to adjust the brightness and the color temperature of the total light emitted by the luminaire 1.As already mentioned above, the controller is advantageously preferably designed such that all control parameters of the various function modes F 1, F 2, F 3 can be influenced by the luminaire 1 or the lighting means arrangement 30 for adjustment purposes by gestures of the user that are as simple as possible within a single detection region DB, wherein this detection region DB is completely surrounded by the illumination region AB. That is, the user is intuitively notified of the spatial range in which he can control the luminaire 1 by gestures.For this purpose, the control device 50 is also preferably designed such that only when the light 1 is switched on, i.e. when light is emitted, function modes such as the setting of the brightness (dimming) or the color temperature can be used. The user can actually perform corresponding gestures in the detection area DB at any time. However, the controller provides that these gestures in the switched-off state of the luminaire 1 are either not recognized or not taken into account, in that the functions are, for example, intentionally programmed / deactivated when the luminaire is switched off. That is, the recognized gestures do not result in control signals for the light fixture arrangement 30 being generated or modified. This control consequently also ensures that the user always immediately sees the result during gesture control, i.e. that the light immediately becomes brighter or darker or cooler or warmer. However, the sensor functions (in standby) also when the light is switched off, in order to sense the movement for setting.In order to make control as easy as possible for the user and nevertheless to accommodate all three function modes (on / off, dimming, color temperature setting) within one and the same detection range DB in a particularly effective and easily detectable manner, three different movement axes B 1, B 2, B 3, which are orthogonal to one another, are defined within the detection range DB. Each of these movement axes B 1, B 2, B 3 respectively includes two movement directions B 1N, B 1W, B 2V, B 2R, B 3R, B 3L. These axes of movement B 1, B 2, B 3 and directions of movement B 1N, B 1W, B 2V, B 2R, B 3R, B 3L can be seen particularly well in FIGS. 3 and 4.A first movement axis B 1 runs perpendicular to the extent of the disk-shaped lamp head 20, i.e. perpendicular to the plane EL of the light exit opening 22 and of the detection window 24. For this purpose, the detection device 40 works with distance detection of the object H from the detection device 40 or the C-MOS sensor 41. in this functional mode F 1, the movement directions B 1N, B 1W are preferably assigned to the control signals such that the lighting means arrangement 30 becomes brighter when an object H or the hand H of the user moves in a first movement direction B 1W away from the lighting head 20. When the hand H moves in the opposite direction of movement B 1N along the first movement axis B 1, i.e. toward the lamp head 20, the lighting means arrangement 30 becomes darker, on the other hand. This is advantageous since the user intuitively selects these movements, since a movement of the hand onto the light head 20 quasi "covers" the latter and thus emits less light. These gestures are symbolized in FIG. 7.With a movement along the first movement axis B 1, the brightness adjustment in both movement directions B 1N, B 1W is preferably continuous in each case. The detection device 40 and / or control device 50 are set in such a way that they require only a few 100 ms in order to first determine the starting position, i.e. the starting distance of the object H from the lamp head 20, and then, in the case of a continuous movement of the object H along the first movement axis B 1, can permanently keep the distance still and evaluate it accordingly. The absolute value of the distance of the object from the light head 20 is not important here, but only the change of the distance during gesture. That is to say that the decisive factor for the brightness change is only the distance between the starting position or height at which the hand H was moved into the beam and a final distance of the movement along the first movement axis B 1. If the user then does not yet agree on the brightness, he can simply retract again at any point in the detection region DB with the hand and move the hand upward or downward for readjustment in the desired direction of movement B 1N, B 1W (see FIG. 7 ).A second movement axis B 2 extends below the luminaire head 20 parallel to the plane EL of the light outlet opening 22 and thus perpendicular to the first movement axis B 1, namely from the front side to the rear side of the luminaire head 20 or vice versa. Along this movement axis B 2 there are in principle also two movement directions B 2V, B 2R, namely once the movement direction B 2V from the front side of the luminaire head 20 towards the frame 10 and once the movement direction B 2R back. This second movement axis B 2 is assigned a function mode F 2, which serves to switch on and switch off the luminaire 1 or the lighting means arrangement 30 again. For this purpose, the control device 50 is advantageously intentionally designed such that both functions, namely the switching on and the switching off of the light 1, are achieved only by a movement of the object H in the movement direction B 2V along the second movement axis B 2, i.e. from the front in the direction of the light frame 10.This gesture is symbolized in FIG. 6. The reverse direction B 2R is not used or is intentionally deactivated.This has the advantage that, if the user wishes to switch on the luminaire 1 and moves from the front with the hand H along the second movement axis B 2 to the rear of the luminaire frame 10 and then pulls back the hand H again, which frequently occurs automatically, the luminaire 1 cannot simultaneously switch off again unintentionally. For switching off, the user has to move again from the front along the second movement axis B 2 with the hand H. Various tests have shown that in this way a particularly user-friendly operation with gestures can be achieved, since it is necessary in the rarest cases to first switch on a light and then immediately switch it off again.The third movement axis B 3 runs perpendicular to the first movement axis B 1 and to the second movement axis B 2, i.e. from right to left or left to right transversely below the luminaire head 20 (see FIGS. 4 and 5 ).Along this third movement axis B 3, the color temperature of the light emitted overall by the lighting means arrangement 30 can be adjusted. In this case, when gesture is made in the one movement direction B 3R, which runs from left to right (as viewed from the front side of the luminaire 1), the color temperature is shifted more into the cold white region, and when movement is made in the reverse movement direction B 3L, from right to left, the color temperature is changed into the warm white region.The detection or recognition of a movement of the object H or of the hand H along the movement directions B 2V, B 2R along the second movement axis B 2 and the movement directions B 3R, B 3L along the third movement axis B 3 is also possible very safely and efficiently with the aid of the detection device 40. For this purpose, the detection range DB is divided into four quadrants Q 1, Q 2, Q 3, Q 4, as is illustrated in FIG. 5. With the aid of the sensor arrangement 41 or the C-MOS sensor 41, it is possible to detect in which quadrant Q 1, Q 2, Q 3, Q 4 an object H enters the detection region DB and in which quadrant Q 1, Q 2, Q 3, Q 4 the object then exits the detection region DB again within a defined time. Solely by this detection of the spatial entry of the object H into the detection region DB and out of the detection region DB, the movements in the different movement directions along the second movement axis B 2 and third movement axis B 3, which each run parallel to the plane EL of the light exit opening 22, can be easily detected and distinguished. If the object H enters the second quadrant Q 2 and exits again in the fourth quadrant Q 4, for example, this is considered to be a movement in the movement direction B 3L along the third movement axis B 3, i.e. from right to left, and the color temperature is accordingly shifted more in the direction of warm white. In the same way, the object movement is detected very easily in the other movement directions B 2V, B 3R. Thus, the most varied movement directions (and desired function modes F 1, F 2, F 3) can be identified reliably and efficiently without, as stated, requiring a complicated detection of the precise movement path or a speed profile or the like.In the two function modes F 2 and F 3 with respect to the movement axes B 2 and B 3, the control is effected in each case in stages. With regard to the second movement axis B 2, this is already clear since, of course, along this movement axis B 2 only either is switched on or switched off. With regard to the third movement axis B 3 for adjusting the color temperature, the control device 50 is configured, i.e. the microcontroller 51 is programmed such that, with each completely detected movement in the movement direction B 3R along this third movement axis B 3, the color temperature is set cooler by one step and, with each completely detected movement along the opposite movement direction B 3L (from right to left), the color temperature is set down by one step. In the present embodiment, there are five stages in each direction.Since the luminaire 1 generally serves to illuminate a working area or movement area of the user, the control device 50 and / or the detection device 40 are configured such that the detection area DB is spatially limited not only laterally but also with regard to the distance from the luminaire head 20. That is to say that the detection region DB ends at a maximum distance a below the plane EL of the light exit opening 22, as is schematically illustrated in FIG. 3. In the present exemplary embodiment of a table light, this distance a amounts to approximately 30 cm. but can basically be preset as desired by the manufacturer. This minimum distance a can be set, for example, by the sensitivity of the sensor arrangement 41 and / or the power of the IR transmitter 42 or preferably by a presetting of the control device 50, for example by suitable programming of the microcontroller 51, so that an object movement which is detected at a greater distance than the maximum distance a from the lamp head 20 is ignored in the further processing.This advantageous device of the luminaire 1 ensures that below the maximum distance a from the luminaire head 20 the movements of the user do not lead to any change in the setting of the control parameters of the lighting means arrangement 30. In the above-described embodiment of the table light 1, depending on the height setting of the light head in the usual use on the desk, for example below 30 cm from the light head 20, advantageously a range of about 15 to about 30 cm above the table surface would remain, in which the user would also move his hand, among other things, in order to write, to browse a book or to perform other actions in the light cone. All these movements can then not lead to an undesired adjustment of control parameters.The control of the luminaire 1 or the lighting means arrangement 30 with the aid of the gestures of the user in the various function modes F 1, F 2, F 3 is explained once again below with reference to the flow chart in FIG. 9.When the lighting means arrangement 30 is switched off, the luminaire 1 is in a standby operating state, which is symbolized here by the block I. In this operating state, it is only checked whether a movement of an object H along the second movement axis B 2 in the movement direction B 2V is detected, i.e. only the function mode F 2 in which the switching on of the light 1 is possible is active here. This query is symbolized in FIG. 9 by step II. As long as the question is not affirmative, the luminaire 1 remains in the standby operating state, but the question is affirmative (y) the luminaire 1 is switched on, which is symbolized by the function block III.It is pointed out here that only positive query results (y) are shown in the flow chart in FIG. 9 for the sake of simpler illustration. If the query is negative, the controller simply remains in the respective query mode or waits for the detection of a corresponding movement signal.In this switched-on state (function block III), different queries VI, VIII, IV, X, XII then run, in which it is checked in each case whether a movement takes place along the different movement axes B 1, B 2, B 3.The query in block IV relates again to checking whether an object H is moving along the second movement axis B 2 in the movement direction B 2V again. This is the gesture which then leads to the luminaire 1 being switched off again. This query therefore also belongs to the second function mode F 2. If the query is affirmative (y), the light 1 is switched off again, which is symbolized by the function block V, and a return to the standby operating state symbolized by the function block I takes place.In addition, as mentioned, when the light 1 is switched on, the operating mode F 1 for dimming (brightness setting) and the operating mode F 3 for setting the color temperature are active.The first function mode F 1 here includes the queries VI and VIII. In the query VI, it is checked whether a movement of the object H along the first movement axis B 1 in the movement direction B 1N takes place from the bottom to the top of the lamp head 20. If this is the case (y), the lighting means arrangement 30 is darker. In the other query VIII, on the other hand, it is checked whether a movement along this movement axis B 1 in the opposite movement direction B 1W takes place away from the lamp head 20. If this is affirmative (y), the lighting means arrangement 30 is set darker, which is symbolized by the function block IX.In the function mode F 3 for setting the color temperature, there are also two queries X and XII accordingly. The first query X relates to the detection of whether a movement along the third movement axis B 3 in the movement direction B 3L takes place from right to left. If this is affirmative, the color temperature of the lighting means arrangement 30-provided it is not yet at the warmest stage-is adjusted warmer by one stage, which is symbolized in block XI. If, on the other hand, it is recognized in the query in block XII that a movement in the opposite direction of movement B 3R from left to right occurred along the third axis of movement B 3, the lighting means arrangement 30 is correspondingly set cooler-provided it is not yet at the coldest stage-here symbolized by the function block XIII.FIG. 9 thus shows particularly well how, by a skillful selection of the movement axes B 1, B 2, B 3 and the movement directions B 1N, B 1W, B 2V, B 3R, B 3L, a particularly safe, efficient and intuitive control of all important function modes F 1, F 2, F 3 can be achieved with the luminaire 1 according to the invention or the control device 50 within a single detection range DB which lies completely within the illumination range AB. It is not necessary to provide further detection regions outside this illumination region AB, for example above the lamp head.FIGS. 10 to 14 show yet another exemplary embodiment of a luminaire 100, here in the form of a self-supporting luminaire 100. As can be seen in FIG. 10, the luminaire 100 (just as the table luminaire 1 of the exemplary embodiment described above) has a luminaire head 120, which is arranged at an upper end of a luminaire frame 110 with a likewise two-link, articulated luminaire arm or arm 112 here. This lamp head can be designed, for example, as described above with respect to the table lamp 1 according to the invention.Analogously to the above-described luminaire frame 10 of the table luminaire 1, the luminaire frame 110 of this luminaire 100 also has a luminaire foot 111 at a lower end for placing the luminaire 100 on a table top (not illustrated) or on the floor. This lamp base 111 consequently forms a lamp base 111 here. Alternatively, here too, instead of a lamp foot 111 for parking, a clamping element for clamping to a table top, a through-table fastening or another lamp base could also be used.From the lamp base 111, a lower member 112 uof an arm 112 extends vertically upward. Here, too, this lower link 112 uof the luminaire arm 112 is connected to the luminaire base 111 via a lower joint 113 u(a pivot joint) such that it can be rotated about a vertical axis in such a way that the lower link 112 u, and thus the entire luminaire arm 112, can be rotated through 360° on the luminaire base 111 in the rotational directions DR 1 in the clockwise and counterclockwise direction. However, in order to slightly simplify the structure of the luminaire 100 and to keep the manufacturing costs lower at this point, the lower joint could also be omitted. In this case, the operator could then still rotate the luminaire 100 together with the luminaire base 111 in order to change the position of the luminaire 100 in the clockwise and counter-clockwise directions of rotation DR 1, which would be far less user-friendly, however.The lower member 112 uand the upper member 112 oof the arm 112 can each be rod-shaped, each with (in the case of a conventional placement of the luminaire; see the above definition of the directions) a front longitudinal edge or front edge 112uv, 112ov facing the user and a rear longitudinal edge or rear edge 112uh, 112oh facing away from the user.At the upper end of the lower link 112u of the arm 112, an upper link 112o of the arm 112 is telescopically hinged via a central hinge 113m. This joint 113 mis designed such that the upper link 112 ocan be pivoted upward in a rotational direction DR 2 about a horizontal pivot axis running perpendicular to the longitudinal axis of the lower link 112 urelative to the lower link 112 uof the arm 112 and can also be pivoted downward again in the opposite direction. The possible adjustment range of the pivot angle is preferably at least 90°-180°, i.e. at least from a horizontal position of the upper link 112 o(equal to 90° relative to the lower link 112 u) to a vertical position of the upper link 112 o(equal to 180° relative to the lower link 112 u).At the upper end 115o of the upper link 112o of the arm 112, as in the above-described embodiment, the lamp head 120 is fixed via a head joint 116. This head joint 116 is also preferably designed in the manner of a ball joint, e.g. also a self-holding ball joint, and thus again allows the luminaire head 120 to be rotated about the two axes of rotation in the direction of rotation DR 3 and DR 4 already described above in connection with FIG. 1.FIG. 11 shows the state of the upper link 112 o, which is completely pivoted upward in the rotational direction DR 2, at a 180° angle relative to the lower link 112 u. As seen therein, the lower member 112u then extends vertically upwardly substantially in common alignment with the upper member 112o. Here too, it is preferably a self-holding joint 113 m, i.e. the joint 113 mis formed in such a way that the upper link 112 oof the arm 112 remains self-standing in any position. In the embodiment of a table light 1 described above, for example, the lower member 12u may be considerably shorter than the upper member 12o (as shown in the figures). In the case of a parking light, this can also be the reverse.In contrast, FIG. 14 shows the horizontal position of the upper link 112 o(equal to 90° relative to the lower link 112 u).Here, as can be seen from FIG. 11, for example, the lower member 112 uis only slightly longer than the upper member 112 o. Depending on the length of the links 112 o, 112 uof the arm 112 and the desired requirements, the luminaire 100 can accordingly be used as a table luminaire 100 or a stand luminaire 100.A particularly advantageous difference of the exemplary embodiment of the luminaire 100 according to FIGS. 10 to 14 compared to the above-described exemplary embodiment of the luminaire 1 according to FIGS. 1 to 8 consists in the concrete configuration of the central joint 113 m, in which namely the members 100 o, 100 uare connected, here as preferably by means of a plug connection 160, 161 carrying current during the intended operation of the luminaire head 120, - comprising a two- or multipolar, coaxial plug connector or plug (e.g. a so-called "jack plug") 160 and a matching plug connector receptacle or socket (e.g. a so-called "jack socket") 161, which can be pulled apart for the transport of the luminaire 100 and can be plugged together for the operation of the luminaire 100. This configuration makes it possible to pack and transport the luminaire 100 in a space-saving manner, even with links 100 o, 100 uwhich may be quite long in total, for example only half as large, as would be necessary without the disassembly. The luminaire is thus particularly mobile, i.e. easily transportable. In addition, the packaging, transport and storage costs can be significantly reduced compared to correspondingly large conventional lamps. Moreover, the connection by means of jack plug 160 and jack socket 161 advantageously ensures that the power supply of luminaire 100 is already established by simple, rapid plugging together of members 112 o, 112 u.The joint 113m is constructed here such that the plug axis along which the plug connection 160, 161 can be plugged together or pulled apart runs perpendicular to the pivot axis about which the members 112o, 112u can be pivoted relative to one another. In the exemplary embodiment shown in FIGS. 10 to 14, this is realized in such a way that the plug 160 simultaneously forms a type of articulated rod of an articulated head 164. This joint head 164 otherwise has in the usual manner a joint eye 164 a(optionally with a joint bearing arranged therein), in which a joint axis 165 ais rotatably mounted. The hinge axle 165a is here again supported by a hinge axle bracket 165 connected to the lower link 112u of the arm 112. In principle, however, other constructions would also be possible. For example, instead of the plug 160, a jack, e.g., the jack 161, could be formed as a link rod of the articulating head and the plug is connected to the upper link 112o of the arm 112, or the connector is directly connected to a hinge axis and the articulating head is connected to the hinge eye (without the intermediate connector) to one of the links 112u, 112o of the arm 112.As can be seen from the enlarged view of the joint 113 mof the arm 112 according to FIG. 13, the joint 113 mcan be secured by means of two threaded pins 162 for securing in the plugged-together state (see FIG. 14 ), wherein the threaded pins 162, which are situated in FIG. 13 by way of example in the jack 161 in the upper link 112 oof the arm 112, firmly clamp a part of the jack plug 160 in the lower link 112 uof the arm 112 in a force-fitting manner by screwing in (see FIG. 14 ). As can also be seen from FIG. 13, the jack plug 160-as is customary for a commercially available jack plug-and also the jack socket 161 each have an inner conductor 160 iand an outer conductor 160 a, which continue through the entire luminaire 100 in the form of cables (not shown everywhere) and thus, in total, ensure a continuous current connection from a USB-C connection on the luminaire base 111 via the respective links 112 i, 112 oof the arm 112 and the central joint 113 mconnecting the two links 112 i, 112 oup to the luminaire head 120. In addition, the joint 113 mis also provided with a cover 163 which is intended to prevent a user from getting into the joint 113 mwith his fingers and possibly clamping the fingers. When used properly, corresponding injuries are effectively prevented.Finally, it is pointed out once again that the devices described in detail above are merely exemplary embodiments which can be modified in a wide variety of ways by the person skilled in the art without departing from the scope of the invention. For example, it is possible to also construct or equip the table light, similar to the embodiment of the stand light, correspondingly with a joint which can be plugged together and pulled apart. It would likewise also be possible to dispense with such a joint in the self-supporting lamp and to use a simpler joint as in the table lamp. It would also be possible, for example, for an energy source such as a rechargeable battery or the like to be arranged in the lamp head or in the lamp frame for operating the lamp. Furthermore, the control device can additionally have a radio module in order to establish a coupling with a smartphone or the like, so that control of the luminaire with a suitable app or the like is also possible as a remote control via such a device. For the construction of the control, the remote control (e.g. by means of the app) and the various control possibilities, in particular for providing a boost mode, a "trainable" control of a (circadian) spectrum control curve and a formation of a total light spectrum using a random control pattern for controlling the LED arrangements, reference is made to the documents DE 10 2014 115 076, DE 10 2014 115 079 and DE 10 2014 115 082, the content of which with respect to these features is incorporated here in this respect. Furthermore, the use of the indefinite article "a" or "an" does not exclude that the features in question can also be present multiple times. Likewise, the term "unit" does not exclude that it can also consist of a plurality of subunits, optionally also spatially separated.List of reference characters1 Lamp / table lamp 10 Lamp stand 11 Lamp base / lamp base 12 Arm 12 o Oberes arm 12 ov Vorderkante arm top member front edge 12 oh Hinterkante arm top member rear edge 12 u Unteres arm bottom member 12uv Vorderkante arm bottom member front edge 12 uH arm bottom member rear edge 13 u Unteres joint 13 m Mittleres joint 14 Connector / USB-C connector 15 o Oberer top portion of top member 15 u Unterer top portion of top member 16 Kopf joint 17 End surface 18 Slit 19 Tab 20 Lamp device / lamp head 20 u Unterseite 21 Lamp housing 22 Light exit opening 23 (annular) disk 24 Detection window 25 Detection window cover 26 Outer wall 27 Partition wall 30 Lamp assembly 31 a Äußerer lamp rim 31 i inner lamp ring 32, 33 lighting means groups 34 warm white lighting means / LEDs 35 cold white lighting means / LEDs 36 reflector 40 detection means / sensor means 41 (IR) sensor / IR sensor / C-MOS sensor 42 IR transmitter 50 control means 51 microcontroller 52 electrical components 100 luminaire / parking light 110 luminaire frame 111 luminaire base / luminaire foot 112 arm 112 oupper link of arm 112 ovprecision edge of the upper link of arm 112 ohprecision edge of the upper link of arm 112 udownpart of arm 112uvprecision edge of the lower link of arm 112 uhprecision edge of the lower link of arm 113 udownpart joint 113 mmid joint 114 connector / USB-C connector 115 oupper end region of the upper link of arm 112 udownpart of arm 112 u Upper member 116 Head joint 120 Lighting device / lighting head 160 Plug connector / plug 160 a Außenleiter conductor 160 i Innenleiter conductor 161 Jack socket / socket 162 Threaded pin 163 Cover 164 Joint head 164 a Gelenk eye 165 Joint axis holder 165 a Gelenk axis EL Plane of the light emission opening AR Emission direction DB Detection region AB Illumination region h Height d Outer diameter b Width dd Diameter DR 1, DR 2, DR 3, DR 4 Rotational directions H Object / hand a Maximum distance B 1 First movement axis B 2 First movement axis B 3 First movement axis B 1N, B 1W Movement direction B 2V, B 2R Movement direction B 3R, B 3L Movement direction Q 1, Q 2, Q3, Q4 quadrants F1, F2, F3 function modes α radiation angle of the illumination areaReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
