Description

The invention relates to a movement sensor-controlled lighting device according to the preamble of claim 1. Such devices are for example from the DE 299 03 904 The applicant known and are based on the principle, common bulbs - incandescent lamps, energy-saving lamps or similar. - To connect in the most compact way with a motion detector in order to then activate and deactivate the light bulbs motion control.

In Advantageously, the carrier module uses the first of these Lamps particular interior or space and sees there in particular the sensor electronics with transmitting and / or receiving antenna in front; Not only is this avoiding that extra Modules must be integrated into the motion base itself; also takes place through this measure a separation of the sensor electronics from those in the mounting base already existing circuits (in particular a conventional electronic ballast (ECG) for the bulbs), so that in particular also from radiation technology and thermal view of the motion sensor simple and space saving can be recorded without about the - temperature-sensitive - Sensor electronics disadvantageous from the lamp ballast electronics heated would become.

The Microwave-based motion detection in conjunction with the very compact arrangement of this known from the prior art product allows it is that such known devices are often indoors, preferably also be used behind lampshades - the microwave technology allows the movement detection of persons to turn on the Device hidden behind a lampshade, so that too Motion detection not aesthetic would disturb.

Just however, in a use as a lighting device for a pendant lamp (i.e., screwed into the bulb socket approximately above a Table or the like. hanging Light, at downwards on the table surface However, directed (first light source) is often a (complementary) lighting desired which is not movement or presence controlled and in particular also a limited, advantageously downwardly directed illumination volume provides. Added to this is the fact that, according to the forms of training common Energy saving lamps, the tubular, elongated, coiled or curved bulbs only a comparatively weak radiation effect in an axial Have direction of the device, i. the (screw) socket opposite and in the hypothetical application of a suspension fixture on an underlying surface directed. common However, bulbs or energy-saving bulbs offer no possibility to the supplementary Lighting in this direction, would still about the cramped space room under a lampshade an additional Offer light source.

task The present invention is therefore a generic motion sensor controlled Luminaire device with regard to its universal usability especially for a hanging operation or the like. with the possibility of an improved Light emission in the axial direction should be offered and ideally this axial illumination also independent of the motion sensor, especially in a continuous light operation, can be operated.

The Task is by the movement design of the lighting device solved with the features of the main claim; advantageous developments The invention are described in the subclaims.

In accordance with the invention advantageously first with the device according to DE 299 03 904 realized advantages (which in terms of their constructive implementation, the design of the lamps in addition to ballast electronics and motion sensor as part of the invention should be included in the present disclosure), and additionally and advantageously achieved that the second light source, further education by means of at least one LED realized, one (preferably permanent) and parallel to the axis along the arrangement, ie allow for suspended mounting directed to an underlying surface illumination emission.

In this way, then, especially for table lamps in restaurants, conference rooms or the like. suitable, even in the case of no detected movement, ie typically switched off first light sources, a (cold) lighting low luminous power and correspondingly low energy consumption available, which then in a luminous operation of the first bulbs (ie typically a gas discharge lamp with curved or coiled tubes) for a providing additional illumination outside the (typically radial) main illumination direction of the first illuminant. This is then also in a favorable manner a compromise between the respective own benefits having usable illuminant types created, according to the invention preferably gas discharge bulbs for the (motion-controlled switching) first light source and an LED (suitable would be an LED grouping or the like.) For the second lighting means are provided. In addition, the realization as an LED would in no way have a disturbing effect on the functionality of the sensor in the interior or intermediate space.

in the Context with the present invention is as interior and / or gap any, above the mounting base Underlying space to understand which by sections of the bulb determined, defined or limited, whereby such interior or spaces otherwise remained unused. Especially in the case of tubular first bulbs - elongated, curved or coiled illuminant tubes - are used as interior or interspaces all To understand areas of space that are within a light source lying, imaginary shell lying.

there the invention is not limited to a particular form or embodiment of a Limited.

So it is particularly preferably, the first lighting means as a gas discharge lighting means to realize, with an associated discharge tube in accordance with the invention is arranged in front of or around the transmitting or receiving antenna, and more preferably this transmitting or receiving antenna at the end or is formed on a flat substrate.

According to the invention contains the mounting base only the conventional ones even in such a socket existing ballast electronics for the first light source (ECG), and only within the scope of a possible Further education could be this Socket in addition the (compact) control or evaluation electronics for the Motion sensor included.

alternative Is it possible, these sensor electronic components also on the (planar) carrier for the Provide transmitting / receiving antenna, which then the complete realization the motion sensor as a module and thus the simple retrofitting existing Sensor lights (eg by inserting the sensor carrier into the base between the bulbs) allows.

In According to the invention advantageously Further development, it is also provided with the lighting device a brightness and / or To provide timing unit, which in the case of a brightness control, which is further preferably light-compensated, an activation or deactivation of the first and / or second lighting means in dependence from an ambient light level. This can, for example a lighting operation in bright daylight environment (despite movement detection) changed become. additional or alternatively, the time-keeping unit according to further development ensures that, for example at predetermined evening hours, the lighting device in continuous operation is operated while otherwise only as needed, namely as a result of detected movement an object, a lighting operation with a predetermined lighting duration triggered becomes.

In There are many possibilities for concrete constructive realization the invention and preferred as LED to be realized second light source on or in the arrangement To attach: First, it is cheap, preferably, the second Bulbs on or in ring- or disc-shaped parts of the transmitting and / or On or put on receiving antenna, which is particularly here the interaction with a resonator as an antenna offers. typically, there is no disturbing influence, and the focus of the LED radiation, possibly supplemented by suitable optical Focusing means, would then axially (i.e., along the longitudinal axis through the moving base or the first lighting means) extend outwards.

A alternative development of the invention provides advantageous to the or in the mounting base, low on the side of the first Illuminant and adjacent thereto, at least one LED, preferred a plurality of LEDs to provide, which is axially parallel to the first bulbs, preferably the gas discharge lamp aligned are and, in the realization as a plurality of LEDs, in kind surrounded by a ring. In this way, advantageously, the mounting base, in particular its edge region outside the first luminous means, use to additional here affordable simultaneously bright (but not necessarily power) LEDs use, which then in the invention advantageous manner as additional Light source permanently lit and / or not by the motion sensor can be activated and thus offer a lighting supplement in the manner described above.

in the Contrary to the above-described embodiments, this is Variant of a plurality of annular around the first bulb LEDs arranged around cheap to realize and in a simple way (namely reaching into the pedestal or housing interior) to contact and electrically control.

Especially In addition, it is suitable for the second lighting means to be arranged in a modular manner. or infectious to design, so that in particular in a simple Form a retrofit operation or a replacement in case of defect possible is.

The result is created by the new Suggested implementation measures measure in a surprisingly simple way, a very effective improvement of the generic technology, such motion sensor-controlled lighting devices are further expanded in their range of application and in particular the lighting and control behavior of such devices in suspension operation on.

The in the 1 Lamp shown schematically is modeled in the outer form devices, as they are commercially available and sold as so-called. Energy saving lights. One with a screw base 10 For a common bulb socket housing provided 12 provides the space for the control or ballast electronics (not shown in detail) of a gas discharge lamp 14 , which can be operated in the usual way with transformed mains voltage.

In the context of the present invention, such a lamp is connected to a motion sensor in such a way that - as shown schematically by the flat carrier board 16 indicated - behind or between the actual bulb 14 the transmitting and / or receiving antenna of a radar motion sensor is arranged, and this radar motion sensor in operation via the planar support element 16 as an antenna emits or receives electromagnetic waves. These are usually in the range between about 2 and about 20 GHz and are thus able to easily not only the bulb tube 14 (or luminous gas contained therein) to penetrate, but also a possible cover or a lampshade that can surround the arrangement shown in the assembled state.

An appropriately used in the context of the present invention, on CW, Doppler or pulse-based radar sensor is in common frequency ranges - 2 GHz, 5.7 GHz or higher - operable, provides by the emitted or reflected radar pulses for a satisfactory Penetration in particular of the bulb 14 and is mounted in the manner shown in a particularly space-saving manner.

The 1 shows by the reference numeral 40 , as on the (as a dielectric resonator 16 trained transmitting or Emp catch antenna a power LED 40 a power of one watt is set up so that these in the representation of 1 their focus of light radiation in upward direction forms, while in the light bulbs 14 sitting spanned (inside space) and radiates through the free opening of the interior to the outside. Unlike the bulb tube 14 (the first bulbs, which are controlled by means of the motion sensor described) is the LED 40 operated as a second light source in continuous operation; On the one hand, the energy consumption of the LED is so low that even with a power saving operation of the overall arrangement of the continuous operation of this LED is defensible, beyond would be overcome in the manner described in the introduction, the problem of lack of lighting in a dark environment with non-activated motion sensor effectively. While in principle the coloring of the LED 40 is arbitrary, it would typically offer the luminescent color the emission spectrum of the bulb tube 14 to adapt, so typically white.

In particular, it is also provided that the lighting means 14 - not like in 1 shown - arcuate, but helical or simple or double helical is formed and so in the form of a spiral (similar to the shape of a submerged low) around the vertical antenna board 16 extends around. In particular, this arrangement allows an optimization of the required space, since the space enclosed by the coiled arc tube interior here in an advantageous manner for receiving the sensor antenna, possibly even in addition to the sensor electronics, is used without additional space in (occupied by the ECG) base housing is needed. In addition, a sensor module designed in this way is preferred on the housing 12 pluggable, is supplied by the electronics contained therein with operating voltage and makes so common energy saving lamps with minimal effort retrofitted.

The detection range of the motion sensor arrangement depends on the intended use and is by appropriate design of the antenna structure on the carrier 16 realized; In particular, a circular detection area (radially symmetrical to the longitudinal axis by the arrangement of 1 ) possible.

alternative to the training shown as a pulse radar sensor is the realization the motion sensor also as working on the Doppler principle Radar sensor conceivable. Here is a movement of a detection object in the detection range of the sensor as a frequency shift between the emitted signal and the reflected received signal, and this frequency shift (Doppler frequency) becomes the movement and Speed detection evaluated.

Further Alternatively to the embodiment shown, a pulse radar sensor is conceivable, which works according to the homodyne principle, and in which broadband Transmit pulses by their pulse shape and duration an effective detection range define; simultaneously and without delay, such a transmission signal then coupled on the receiving side in the motion sensor to a aufzusteuern non-linear mixer element. The resulting mixer signal is then evaluated for motion detection.

Another embodiment will be described with reference to FIG 2 to 6 described: A lamp of the type of a commercial energy saving lamp corresponding fixture 20 has a gas discharge bulb, which in turn consists of three elongated, bent at the upper end tube pairs 22 exists, the, cf. the sectional view in the 3 and 4 , on top of a base housing 24 Describe a triangular shape and thus limit an elongated, triangular clear intermediate or interior space.

While the socket housing 24 in an otherwise known manner a (not shown in the figures) ballast for operation of the bulbs 22 has, is the sensor electronics including transmitting and receiving antenna on a flat carrier board 26 which is designed in terms of their length and width dimensions so that they in the elongated-triangular space 28 can be used. A contact with the socket housing 24 contained lighting or control electronics and a power supply provided here via ground-side connection contacts 30 on the narrow side of the carrier board 26 ,

At the other end, this one has as a dielectric resonator 32 trained antenna on, the, see. the clipping according to 6 , has a cylindrical shape with a diameter of about 8 mm and a height h of about 4 mm.

Also, as in the 2 indicated by dashed lines and in the 3 . 5 . 6 Immediately shown, an LED (1 watt power LED) arranged so that these partially into a bore in the resonator 32 extends, but also protrudes with this light head out of this. Thus, the power LED becomes an integral part of the carrier board 26 , Can thus be easily mounted and wired together with their electronic components.

The carrier board 26 is in the illustrated embodiment of an elongated metallic shielding element 34 surrounded, from which only the end of the resonator 32 protrudes. As in 2 The resonator section also extends above the tube pairs 22 , here a cap 36 is provided. This is convenient and permeable to the emission spectrum of the LED 42 to design, z. B. as Plexiglas cap.

In addition, the shows 2 laterally accessible controls in the form of suitable actuators on the carrier board 26 caused by a distance between two adjacent tube pairs 22 are operable and for adjusting a switching threshold for the ambient brightness (the - actually compensated - brightness sensor is not shown in detail in the figures), a detection range of the motion sensor and a minimum light duration after switching on, if no re-motion is detected serve.

In an otherwise known manner, this device is used in conventional light bulb screw sockets and - supplied with operating voltage - including the Bewegungssensor- and brightness control electronics. Especially in hanging mode (ie the reverse mounting direction of the image representations of 1 and 2 ) would then, suitably set to steady light, the LED 42 permanently a lying under the arrangement surface, z. B. table surface, bright, but energy illuminate sparingly, and when approaching a person would then the bulbs 22 additionally activated, the LED 42 also in this operating state, the lighting in the downward direction, so no maximum illumination of the bulbs 22 , added.

Further education is it also possible, the inventive light assembly through a twilight or brightness sensor unit to complete, the activation or Deactivating the first and / or second lighting means additionally dependent on makes a current ambient light level, and / or the additional one ambient light dependent Brightness adjustment of the bulbs makes. On this way let yourself for example, an activation of the first lighting means by movement then prevent when a very bright ambient light level turns on this bulb unnecessary would do.

The 7 and 8th show a further embodiment of the present invention. The reference numerals correspond to the above embodiments insofar as they denote identical and equivalent components and assemblies.

Accordingly, a serving as a mounting base housing 12 (typically realized as an injection molded part of a plastic material) on the bottom side a screw base 10 for interaction with otherwise known light sources, so that the device shown can be used in common lights.

Like the sectional view of the 8th shows contains the housing 12 with the reference numeral 23 symbolically illustrated ballast electronics for the discharge bulbs 22 (as a first lighting means), further a pair of adjusting pins 18 . 20 for functionality to be set by a user in the device, such as the distance threshold of the motion sensor (symbolically referred to as an elongate module 26 as described above, and with end-side resonator antenna 32 realized). This embodiment additionally shows a brightness control (twilight circuit) realized by means of a phototransistor 60 and a plurality of around the circumference of the housing 12 arranged around, inside the housing by means of a light guide 62 optically connected light entry openings 66 wherein a brightness signal of the phototransistor 60 be evaluated in-house with a brightness sensor electronics and z. B. can cause, for example, in very bright ambient light conditions no illumination at all by the light source of the device shown.

During, analogously to the aforementioned first or second embodiment, the first lighting means in the form of the three gas discharge tubes 22 and the central elongate high frequency module 26 with frontally projecting antenna 32 are realized, the embodiment shown differs 7 . 8th by the realization of the second light source. Here are these as a ring of a total of 8 LEDs 50 implemented on a flat side (the side of the first bulb 22 ) of the housing 12 annular and circumferentially edge are arranged. More precisely, compare the sectional view of 8th , the LEDs, together with a plug or mounting seat of the discharge tubes 22 , on one end of the housing 12 provided carrier mounted. In this case, the LEDs extend along the longitudinal direction of the arrangement, so that a light cone emitted by the individual LEDs has its maximum radiation parallel to the longitudinal axis, ie, in the plane of the figure, upwards.

As LEDs 50 For example, power LEDs (eg with a power of 1 watt) can be used, however, depending on the field of application and due to the plurality of individual LEDs used, it is certainly sufficient, in this case low-priced low-power LEDs which are reduced in electrical power consumption use.

As well as the 7 and 8th illustrate, the embodiment shown is enclosed by a glass dome 70 which on the one hand provides protection for the various aggregates, on the other hand offers the opportunity for optical effects by suitable optical design (eg coloring or matting) and generally gives the unit shown the character of an otherwise known, easy-to-handle light bulb or energy saving lamp. This also makes it immediately apparent from the user's point of view that the present device is ideally suited, for example, for replacing an existing light bulb screw base of a luminaire with a simple bulb by the present technology, with the described advantages. In addition, the glass ball used uses 70 the effect of that of the RF module 26 (or the antenna resonator 32 ) radiated RF waves easily the glass dome 70 penetrate insofar as just used the high-frequency motion technology synergistically with the shown, protected by the dome unit.

As an additional development (not shown in the figures), it is possible to provide the device according to the invention with a timing such that - depending on the time of day - different modes of operation of the lamp device are possible: At predetermined times, for example, the first bulbs are operated in continuous operation, without that a motion detection is necessary; At other times, the lamp activation is triggered by the motion sensor, by means of the carrier board and the end resonator 32 realized in the present embodiments.
