Description
Technical Field
The invention relates to a height-adjustable luminaire comprising at least one burner, at least one ceiling housing, at least one height-adjusting unit with at least one cable and at least one control unit.
Background
From the prior art there are known height-adjustable ceiling lamps with a lamp cap suspended at a ceiling fixing unit by means of a cable. For example, DE 20 2007 017 625 U1 describes a height-adjustable ceiling lamp in which the cable for suspending the lamp head is wound onto a mechanically preloaded winding drum which is fixed to the ceiling of the room. In order to keep the suspended lighthead in its current vertical position, the winding drum has a winding brake which prevents the accidental unwinding of the cable wound on the winding drum.
In the known height-adjustable ceiling lamp, the disadvantage is that the adjustment of the vertical position or height of the lamp cap requires manual movement of the lamp cap.
Furthermore, height-adjustable ceiling lamps as shown in DE 20 2007 017 625 U1 face a corresponding risk of contamination. In addition, the lighting arrangements that can be achieved with the aid of height-adjustable ceiling lamps are not suitable for all purposes and lighting situations.
Disclosure of utility model
In view of this, it is an object of the present invention to provide a height adjustable light emitting device that can be used in a variable environment and that can be used to create various lighting arrangements and scenes. The height-adjustable lighting device should also be as comfortable as possible and adjusted in a safe manner and method.
The object of the invention is achieved in particular by a height-adjustable light-emitting device having:
At least one of the lamp heads is provided with a lamp cap,
At least one ceiling housing, which is arranged in the ceiling housing,
At least one height adjustment unit with at least one cable, and
-At least one control unit.
The control unit is configured for actuating the height adjustment unit such that the lamp cap can be set into a first use state in which the lamp cap is suspended by means of the at least one cable and forms a ceiling lamp, and into a second use state in which the lamp cap is submerged in the ceiling housing and forms a submerged ceiling lamp.
It is a key point of the invention in concept that the height-adjustable lighting device is configured such that it is not only configured as a suspended ceiling lamp, but also as a submerged ceiling lamp. Thus, completely different lighting situations can be created with a single lighting device. In the first use state, a relatively local illumination of the room area in the environment of the suspended lighthead can be achieved with the light emitting device, whereas in the second use state a larger illumination of the room area can be achieved. In addition, a configuration of the light emitting device is created with the second use state (in which the light emitting device forms a ceiling lamp by sinking into the ceiling housing), which configuration is substantially different from the first use state (in which the light emitting device is configured as a ceiling lamp). The light emitting device according to the invention thus combines two completely different illumination concepts in a single device.
The first use state relates to the basic construction of the height-adjustable light-emitting device as a pendant lamp. The actual vertical extension of the pendant may be designed to be variable. Thus, there may be a variety of underutilized conditions with respect to the first utilized condition.
The height adjustment unit is preferably configured to change the position of the burner in the vertical direction in accordance with a control instruction received from the control unit. This aspect relates to a switching from a first to a second use state or from a second to a first use state, and also to a variable formation of the first use state by means of adjusting the height or vertical position of the suspended burner. The different adjustable vertical positions of the burner can be regarded as an underutilized state of the more general first use state, wherein the light emitting device is constituted as a pendant lamp.
The use of a height-adjustable light emitting device according to the invention provides a solution involving the creation of at least two different use states. These usage states are used to create different lighting arrangements.
In the context of the present invention, the direction along the direction of action of gravity is denoted (substantially) by the vertical direction.
A submerged ceiling is to be understood as a non-suspended ceiling in particular. Thus, in the second use state of the burner, only the burner of the light emitting device is visible. Any components of the height adjustment unit are not directed outwards and/or are not visible outwards.
In particular, in the second use state of the burner, only the downwardly directed or protruding visible face of the burner is visible. This includes in particular the light-emitting surface of the burner.
The second use state of the lamp base is preferably understood to be a completely immersed construction of such a ceiling lamp. The ceiling lamp preferably does not extend into the room. In other words, the ceiling lamp does not protrude beyond the ceiling of the room in the room.
The height adjusting unit is used for adjusting the height of the lamp cap. This is advantageously achieved in that the height adjustment unit can change the length of the at least one cable between the ceiling housing and the burner.
In an exemplary embodiment, the height adjustment unit has a drum for at least one cable, in particular for each cable provided for suspending the burner, a portion of the cable being wound onto said drum.
For height adjustment, the reel of at least one cable is coupled to a drive which, upon receiving a control instruction, rotates the reel in order to wind up or unwind the cable. Thus, the length of the cable section between the ceiling housing and the burner can be varied. The height adjustment unit must be constructed so that the vertical position of the burner can be changed according to the received control instructions.
The cable for suspending the lamp cap from the ceiling housing is preferably designed as an electrical cable which can simultaneously be used to supply the lighting means in the lamp cap. Furthermore, the cable may be provided for communication, in particular for transmitting sensor data and/or control instructions. Alternatively, the cable may be constituted as a rope, e.g. a metal rope, and the power supply of the burner may be via a separate line.
The ceiling housing is preferably arranged or can be arranged so as to be immersed in the ceiling of the room, wherein the ceiling housing has at least one baffle surface which is arranged or can be arranged in alignment with the ceiling of the room. A room ceiling located in a building or room, which should be equipped with a height-adjustable light emitting device according to the invention, may be referred to as a room ceiling in particular. Preferably, the recess is introduced into the ceiling of the room for this purpose. Furthermore, a suspended ceiling of the room can be constructed, in which a recess can be formed for accommodating the ceiling housing.
In particular, the at least one baffle surface is configured such that, in the use state (second use state) of the light-emitting device as a ceiling lamp, the at least one baffle surface is configured in alignment with the room ceiling and in alignment with the light-emitting surface of the base.
The roof housing preferably has at least one baffle surface. Therefore, the ceiling housing is designed not to be completely open. Preferably, the baffle surface is configured such that any component that is configured in the ceiling housing is partially, preferably almost completely, invisible. The component or the unit located in the ceiling housing in this way may be, for example, at least part of the height adjustment unit or the control unit or the communication interface.
By forming the baffle surface at the ceiling housing, the elements in the ceiling housing are effectively protected from contamination.
The baffle surface of the canopy housing also contributes to the fact that the height-adjustable luminaire is perceived as an integral unit in the second use state and the burner almost disappears in the canopy.
Furthermore, a plurality of baffle surfaces or baffle surfaces can be formed from a plurality of sections that are preferably spaced apart from one another. This achieves that the baffle surfaces individually adapt to the respective shape of the burner.
Preferably, in the second use state, the burner is arranged in the ceiling housing such that a gap is formed between the outer circumference of the burner and the baffle surface. In other words, the burner is preferably designed (slightly) spaced apart from the at least one baffle surface. This preferably involves a gap being formed between the outer circumference of the burner and the baffle surface.
Further, the base may be shaped such that the base has an outer circumference Xiang He inner circumference. In this case, in the second use state, the base is arranged in the ceiling housing such that a gap is formed between the outer circumference of the base and the baffle plate and between the inner circumference of the base and the baffle plate surface.
An opening may be formed in the baffle surface, wherein the cross section of the opening corresponds to the configuration of the base surface of the lamp cap. For example, if the base has a rectangular shape, the opening in the baffle surface is likewise rectangular in shape. The opening cross section is formed here to be larger than the cross section of the base surface of the base. This achieves that the burner can be arranged in a manner that it is immersed in the ceiling housing.
The bottom surface of the lamp cap is preferably formed substantially by the shape of the light-emitting surface of the lamp cap.
For example, if the base has an annular bottom surface, the opening in the baffle surface can likewise have an annular opening cross section. In this case, the baffle surface is composed of at least two sections (i.e., an inner section and an outer section). In this case, the inner and outer sections form an annular open cross section.
The opening of the baffle surface can be formed as an opening of a housing into which the lamp base can be immersed, wherein preferably no further components of the lighting device are formed in the housing. Preferably, only at least one lead-through channel for at least one cable is formed. By means of such a through-channel, the cable can be guided outwards from the ceiling housing, wherein at the same time the components of the light-emitting device located in the ceiling housing are reliably protected from dust and other contaminations.
Preferably, the lamp base has at least one lighting means which is connected in communication with the control unit and is designed to change its brightness in accordance with commands received from the control unit.
By means of the embodiment of the lighting means device with the possibility of changing its brightness, it is achieved that the lighting device that has been used variably can be changed more effectively in terms of the lighting conditions to be achieved.
It is possible that the lamp cap has at least two lighting means, wherein a first lighting means is formed at the lower side of the lamp cap and at least a second lighting means is formed at the upper side of the lamp cap, wherein the at least two lighting means are preferably activated and/or adjusted in terms of their brightness depending on the current state of use.
For example, it is possible to activate only the first lighting means in the second use state, so that the lighting device acts as a ceiling lamp.
Furthermore, it is possible to activate only the second lighting means in the second use state, so that indirect illumination is produced as a result of the preferably formed gap between the base and the baffle surface.
For example, in a first use state, two light emitting mechanism devices may be activated. This results in the greatest possible illumination of the pendant lamp.
Preferably, at least the first light emitting device is enabled in the first use state. As already described, two lighting means can likewise be activated.
In the second use state, the first lighting means or the second lighting means are preferably activated.
The brightness of the individual lighting means can be adjusted, in particular in the first operating state, with respect to the respectively provided height of the ceiling lamp. For example, the brightness may decrease as the height of the ceiling lamp increases.
Preferably, a substantially closed housing section is formed in the ceiling housing, in which housing section a part of the height adjustment unit and the control unit are arranged.
A substantially closed housing section is understood to mean in particular a housing section having only an opening for forming the passage. The at least one threading channel is used for threading the at least one cable outwards from the height adjusting unit.
With such a closed housing section, components located in the ceiling housing (e.g. the height adjustment unit and the control unit) can be effectively protected from dust and other dirt.
In one possible embodiment of the invention, the ceiling housing can comprise a cover side in addition to the side walls. The cover side is opposite any baffle face. This achieves that all sides of the ceiling housing can be formed substantially in a closed manner. In this embodiment of the ceiling housing, the height-adjustable light-emitting device according to the invention is particularly easy to transport. Thus, the components located in the roof housing are particularly well protected during transport or during delivery.
In another embodiment, the ceiling housing may be closed upwardly only in the installed state. In this embodiment, the cover side described above is missing. The cover side is then formed by a section of the ceiling of the room. This embodiment of the invention achieves that the components located in the ceiling housing are easily accessible when the height-adjustable light emitting device is disassembled. This simplifies the replacement of any necessary temperature regulation or possibly defective components.
It is possible that at least one sensor device with at least one sensor is arranged at the lamp head, wherein the at least one sensor is configured as a near field sensor configured for detecting a user's hand in the vicinity of the sensor as a contactless control instruction.
For example, an infrared sensor may be used as a near field sensor to detect emitted infrared radiation when a user's hand is involved in the detection region. Furthermore, the sensor device may have a radiation source (e.g. an infrared light source) and a corresponding at least one sensor which detects radiation emitted by the radiation source and reflected by the object in the detection area. As such, any sensor type may be used as a near field sensor that reacts to near contactless, i.e. without direct contact. Possible embodiments of the near field sensor include inductive or capacitive proximity sensors, gratings or ultrasonic proximity switches that emit an ultrasonic signal and react to the reflection of the ultrasonic signal at objects in the sensor environment.
It is essential that the sensor device has at least one sensor which allows a contactless operation or triggering of the respective sensor in order to detect the control command in a contactless manner. The detection area of the near field sensor is located in the vicinity of the sensor and preferably has a maximum distance from the near field sensor of less than 20cm, more preferably less than 10 cm.
It is only crucial that the near field sensor has a detection area for an object, in particular a user's hand, which detection area is small enough on the one hand to prevent accidental triggering of control commands and wide enough on the other hand to allow the control commands to be generated in a contactless manner by means of gestures.
Gestures that may be used to generate control instructions are not particularly limited. Typically, a near field sensor distinguishes between a state in which no object (e.g., a user's hand) is located near the sensor and a state in which an object (e.g., a user's hand) is located near the sensor. For example, a gesture may be characterized in terms of a dwell time of an object in the vicinity of the sensor, and detected in terms of the dwell time. For example, a gesture may be characterized by a maximum dwell time of an object within a detection region of the near field sensor or a minimum dwell time of an object within a detection region of the near field sensor. Likewise, gestures may be characterized and detected by objects entering and exiting the detection zone multiple times, which may be accomplished by a hand reciprocating multiple times through the detection zone.
In addition, the detection of different gestures can be achieved by the sensor device having a plurality of near-field sensors spaced apart from each other or having a directionality and different orientations.
The first gesture may be characterized by a trigger of the near field sensor for a predetermined minimum duration (e.g., at least one second or half second). The second gesture may be characterized by a corresponding trigger for a predetermined minimum duration of the further near field sensor. In this case, the sensor device should preferably be adapted to detect at least two different, distinguishable gestures.
In another embodiment of the invention, the first gesture or the second gesture is detected when an object (e.g., a user's hand) is within a detection region of the sensor associated with the first gesture or the second gesture for longer than a predetermined minimum duration, such that the sensor is triggered for longer than the predetermined minimum duration. Here, the control unit and the height adjustment unit are configured to maintain movement of the lighthead as long as the hand is located within the detection area of the sensor.
Once the hand leaves the detection area of the sensor, the movement of the lighthead ends. According to this embodiment of the invention, the duration of the movement of the burner in the vertical direction thus corresponds to the duration of the sensor activation. In this way, a particularly intuitive method for adjusting the height of the burner can be created.
By means of the embodiment of the sensor device with at least one near-field sensor, an extremely comfortable solution for the height adjustment of the burner of the height-adjustable lighting device according to the invention is provided. On the one hand, no contact with the lighting device is required, so that no risk of damage or contamination, in particular of the burner, occurs. On the other hand, gesture-based pendant height adjustment control provides an intuitive, easy to understand adjustment possibility with which no additional equipment is required to adjust the height of the lighthead.
The sensor device may have a plurality of near field sensors. In this case, different gestures may be detected by triggering different near field sensors. Likewise, a gesture may be characterized by triggering multiple near-field sensors simultaneously. The combination of the evaluation of the triggering duration and the number or recognition of the triggered near field sensors also allows different gestures to be detected by means of the sensor device. At least two different gestures should be able to be detected.
After detecting and recognizing the gesture, the control unit is preferably further configured to generate a control instruction corresponding to the recognized gesture and send the control instruction to the height adjustment unit. Thus, the control unit may detect a first gesture which results in the generation and transmission of a control instruction which causes the height adjustment unit to move the lighthead in a vertical direction. Upon detection of the distinguishable second gesture, the control unit generates and sends a control instruction to the height adjustment unit, which control instruction results in a downward movement of the lighthead in the vertical direction. This enables a contactless gesture-based adjustment of the burner height.
The control unit preferably has a computing unit, for example a microcontroller or another processor unit. The control unit is configured to receive and evaluate the signals detected by the sensor device in order to be able to correlate the detected signals with different gestures. In particular, the control unit may be configured to detect the duration of triggering of the near field sensor by an object in the detection area and to characterize different gestures according to the duration of the sensor signal.
The communication connection of the control unit with the sensor device and/or the height adjustment unit may be realized in the form of a cable connection, for example by means of a corresponding electrical connection. Such an electrical connection may be at least partially or completely formed by at least one cable between the lamp cap and the ceiling housing.
Furthermore, the communication connection may be implemented by means of a wireless transmission method (e.g. via bluetooth or similar interface).
The height-adjustable lighting device preferably has at least one communication interface for communication connection with at least one control unit. The communication interface may be formed as part of the control unit. Furthermore, the communication interface may be formed in the ceiling housing.
The communication connection of the control unit with the external device can be constructed by means of a communication interface. The external device may be, for example, a mobile phone, a tablet computer, or a controller. The control instructions may be triggered via such external devices. In this case, the gesture-based control can be freely combined with the control via the external device, for example by triggering a control command for the movement of the burner in the vertical direction by means of the external device and triggering a control command for ending the movement by means of gesture control, or vice versa.
In a preferred embodiment of the invention, the lamp base has at least one lighting means device which is connected in communication with the control unit and is configured for changing its brightness in accordance with a control command sent from the control unit. This allows to simply adapt the brightness of the light emitting device.
The communication connection between the at least two lighting means and the control unit is realized in that the change in the brightness of the lighting means is controlled by means of a corresponding gesture which is detected by the sensor means and converted by the control unit into a corresponding control command for the at least one lighting means.
At least one of the first and/or second lighting means may for example have a plurality of light emitting diodes. For example, the light emitting diodes are arranged side by side in a row with each other in the lamp cap.
In another preferred embodiment, the control unit is switchable between a first mode and a second mode. The first mode is for changing the position of the burner in the vertical direction. The second mode is used to change the brightness of the two light emitting mechanism devices.
In a further preferred embodiment, the control unit is configured for switching from the second mode to the first mode when a third gesture for mode switching is detected at the sensor device. Thus, the sensor device and/or the control unit is configured to be able to detect the third gesture. The switch from the first mode to the second mode may be triggered by a third gesture detected at the sensor device. This simplifies the operation of the ceiling lamp, since the user can control the brightness or height of the ceiling lamp in a targeted manner.
In another embodiment of the invention, the control unit is configured to automatically switch from the first mode to the second mode when it is in the first mode for a preset time and no gesture is detected. This further simplifies the operation of the height adjustable light emitting device. By automatically switching to the second mode it is ensured that an unfamiliar user can initially only change the brightness of the pendant. The function for adjusting the height of the lamp cap is rarely required in normal use, which must be triggered by a third gesture before the vertical position of the lamp cap can be adapted with the first gesture and the second gesture. The preset time for the control unit to switch to the second mode may be, for example, 10 seconds or 5 seconds.
It is also preferred that the control unit is configured for detecting a fourth gesture or a fourth and fifth gesture.
In a further preferred embodiment, the sensor device has at least two near field sensors, wherein the sensor device is configured to detect the first gesture when the user's hand is detected at the first near field sensor for a preset minimum time, and to detect the second gesture when the user's hand is detected at least the second near field sensor for a preset minimum time, and to detect the third gesture for mode switching when the user's hand is detected at both the first near field sensor and the second near field sensor for a preset minimum time or less. The first near field sensor and the second near field sensor are preferably positioned at the lighthead such that the respective detection areas are spaced apart from each other. With the aid of this embodiment, a particularly simple operation of the lighting device can be achieved.
Preferably, the control unit is configured for actuating the height adjustment unit such that the burner occupies a submerged position in the ceiling housing when deactivated, in particular when all the lighting means are deactivated.
In other words, the control unit is configured to configure the light emitting device as a ceiling lamp in the deactivated state, but may also be configured as a ceiling lamp in the activated state.
This reduces the risk of possible injury caused by unlit ceiling lamps located in the room. Thus, the user is not accidentally bumped into the unlit ceiling lamp.

Detailed Description
Hereinafter, the same reference numerals are used for the same and identically functioning components.
Fig. 1 shows a lighting device according to the invention, which has a ring-shaped burner 10. The lamp cap 10 is in a second use state, which is also shown in fig. 3.
In addition to the annular burner 10, the luminaire has a ceiling housing 20, three height adjustment units 30, each having a cable 32, and at least one control unit 40. The height adjusting unit 30 and the control unit 40 are located in the ceiling housing 20. The ceiling housing 20 is arranged in such a way as to sink into the room ceiling 95. The ceiling housing 20 has a baffle surface 22 that is disposed in alignment with the room ceiling 95. In the present case, the baffle surface 22 is composed of an inner section 22a and an outer section 22 b.
It can be recognized that the two sections 22a and 22b are arranged in alignment with the room ceiling 95. By means of such a ceiling housing 20, the base 10 can form a completely immersed ceiling lamp 90 in the second use state shown here.
In the present case, three height adjustment units 30 are constructed. According to the sectional views shown in fig. 1 and 2, only two height adjustment units 30 can be identified. In fig. 4 and 5, three height adjustment units 30 are shown to be formed in the present embodiment. Alternatively, only two height adjustment units or more than three height adjustment units may be formed.
A substantially closed housing section 29 is formed in the ceiling housing 20, in which a part of the height adjustment unit 30 and the control unit 40 are arranged. This part of the height adjustment unit 30 is in particular a cable drum and a corresponding drive for winding and unwinding the cable 32.
Only a small opening is formed in the ceiling housing 20 to form the through passage 23. The cable 32 can be guided outwards from the ceiling housing 20 through the through-passage 23. The burner 10 is then fixed at the cable 32.
In the present case, the ceiling housing 20 is designed such that it is closed on all sides. In particular, the canopy housing 20 also has a cover side 41. This achieves a particularly simple operation of the light emitting device in the uninstalled state.
Alternatively, the ceiling housing may not have a cover side. In this case, the closed housing section 29 is formed only when the luminaire is installed or assembled in the room ceiling 95.
In addition to the second use state shown in fig. 1, which shows the configuration of the light emitting device as a ceiling lamp 90, a first use state as shown in fig. 2 is also possible. The (first) use state shows the configuration of the light emitting device as a pendant lamp 80. In this case, the lamp cap 10 is suspended at the cable 32 in the unfolded state, so that the pendant 80 is formed.
In fig. 2, it can be seen that an opening 28 is formed in the baffle surface 22. The opening 28 has an opening cross section corresponding to the bottom surface of the lamp cap 10. The opening 28 is in turn formed as an opening of the housing 21, wherein no other components of the lighting device are formed in the housing 21 and only the lead-through channel 23 for the cable 32 is formed.
Therefore, it is ensured that the components located in the ceiling housing 20 cannot be directly seen even in the first use state when the light emitting device is viewed from below. In addition, components located in the ceiling housing 20 are protected from contamination and undesired effects.
The base 10 has at least one lighting means. In the present exemplary embodiment, two lighting means are formed at the base 10. The light emitting mechanism device is communicatively connected to the control unit 40 and is configured to change the brightness according to a control instruction received from the control unit 40. The first lighting means 51 are formed at the lower side 11 of the lamp base. The second lighting means 52 are formed at the upper side 12 of the lamp base. The lighting means are preferably activated and/or adjusted in terms of brightness depending on the current state of use.
In a first use state, as shown in the configuration of the lighting device as a pendant 80 in fig. 2, at least the first (i.e. downwardly directed) lighting mechanism means 51 is preferably activated.
In a second use state (in which the light emitting device is configured as a ceiling lamp 90), as shown in fig. 1, the first light emitting device 51 and/or the second light emitting device 52 is activated. When the second light emitting device 52 is activated in the second use state, indirect light is generated. When the first lighting device 51 is activated in the second use state, a direct illumination of the ceiling lamp 90 is formed.
The provision of indirect illumination is shown in fig. 3. Fig. 3 shows a second use state in which the lamp cap 10 is arranged such that a ceiling lamp 90 is formed. It can be recognized that the opening 28 (see fig. 2) is formed such that the opening cross section corresponds to the bottom surface of the lamp cap 10. The gap 25 is formed between the outer circumferential direction 15 and the baffle surface 22. A corresponding gap 25 is also formed between the inner circumferential surface 14 and the baffle surface 22. Thus, the light generated by means of the second light emitting means 52 may be indirectly emitted downwards via the gap 25. Indirect lighting may thus be provided.
It can also be recognized in fig. 3 that the baffle surface 22, including the inner section 22a and the outer section 22b, is disposed in alignment with the room ceiling 95. Furthermore, the baffle surface 22 is arranged in alignment with a light-emitting surface 55 of the base 10, which is formed by means of the first lighting means 51. Thus, the light emitting device forms a fully submerged ceiling lamp 90 in the second use state.
The views shown in fig. 4 and 5 of the light emitting device in the configuration as a pendant 80 illustrate that both the first light emitting mechanism means 51 and the second light emitting mechanism means 52 are planar. The luminous means are formed by a plurality of light-emitting diodes which are arranged alongside one another in the horizontal extension of the upper side 12 and the lower side 11 of the lamp base.
Preferably, the lighting mechanism device is steplessly dimmable. The shape of the lamp cap 10 is annular, wherein the shape of the lamp cap is not limited to this shape according to the invention.
Fig. 6 to 10 show a second exemplary embodiment of a lighting device according to the invention, in which the base 10 is embodied in the form of a cuboid.
The light emitting device according to the second embodiment shown in fig. 6-10 has substantially the same components. In the described embodiment, the lamp cap 10 can also be suspended and form a pendant 80 (fig. 7) in the first use state. In the second use state, the lamp cap 10 is immersed in the ceiling housing 20 and forms a ceiling lamp 90 (fig. 6). The opening 28 of the baffle plate 22 in turn has an opening cross section which corresponds to the configuration of the bottom surface of the lamp cap 10. The opening cross section of the opening 28 is thus rectangular in shape, so that the cuboid-shaped lamp cap 10 can be accommodated in the opening 28. The opening 28 has a larger cross section than the bottom surface of the burner 10. It is achieved thereby that a gap 25 can be formed between the outer circumference 15 of the burner 10 and the baffle surface 22. The light emitting device according to the second embodiment has two height adjusting units 30. Thus, two cables 32 are provided, at which the burner 10 is suspended, and via which the light emitting device can be set to a first or a second use state.
The sensor device with the first sensor 16 and the second sensor 17 is also formed at the burner 10. The sensors 16 and 17 are configured as near field sensors configured to detect a user's hand in the vicinity of the sensors to detect gestures as non-contact control instructions.
Furthermore, at least one communication interface 45 is designed for communication connection with at least one control unit 40.
The cable 32 serves on the one hand to fix the lamp cap 10 at the ceiling housing 20 and on the other hand to supply power to the lamp cap 10.
The height adjustment unit 30 is configured for changing the length of the section of the cable 32 between the ceiling housing 20 and the burner 10, in order to thereby be able to adjust the height or the vertical position of the burner 10.
The height adjusting unit 30 is electrically controllable to adjust the height of the lamp head 10. The height adjustment of the burner 10 is also electrically performed. The mechanism for this is not particularly limited, and may be formed, for example, by a motor-driven reel on which the cable 32 is wound or unwound.
Once an object is located in the vicinity of the sensors 16 and 17, the sensors generate a detection signal. Upon detection of an object in the vicinity of the sensor, the sensors 16 and 17 send detection signals to the control unit 40. Preferably, the detection signal is sent to the control unit 40 as long as the object in the vicinity of the sensor is within the respective detection area of the sensors 16 and 17.
The control unit 40 receives the detection signals of the sensors 16 and 17, detects the duration of the detection signals and information of which sensor 16, 17 sent the detection signals. Thus, the control unit 40 can distinguish between different gestures performed by the interventional sensors 16 and 17 in the detection region. The control unit 40 detects the duration of the intervention in the detection area of the respective sensor 16 and 17 and recognizes the movement as a first gesture if the duration of the intervention is longer than a preset minimum time, for example.
The second gesture is characterized, for example, by the user moving a hand into the detection area of the second sensor 17. The control unit 40 may thus recognize the duration of intervention into the detection area of the second sensor 17 and recognize the movement as a second gesture. The lighthead may be moved up or down depending on the gesture detected.
Furthermore, it is possible that, for example, a third gesture is detected, the control unit 40 may switch between the two modes. In the first mode, detection of a corresponding gesture causes a control instruction to be sent to the height adjustment unit 30 to move the lighthead 10 up or down.
In the second mode, the detection of the gesture causes a control instruction to be sent to the lighting mechanism device so that, for example, the brightness of the lighting mechanism device can be changed in accordance with the detected gesture.
Preferably, the control unit 40 is configured such that the height adjustment unit 30 is operated such that the burner occupies a submerged position in the ceiling housing 20 when all the lighting mechanism devices are deactivated.
The communication interface 45, in particular as part of the control unit 40, may be formed in the ceiling housing 20 for communication connection with at least one control unit 40. This enables wireless transmission methods, for example via bluetooth or similar interfaces. Communication connection with an external device is realized. The external device may be, for example, a mobile phone, a tablet computer, or a controller or remote control. In this case, gesture-based control may be freely combined with control via an external device.
