LAMP WITH A CONFIGURABLE SENSOR, MOBILE DEVICE FOR CONFIGURATION AND PICKING OF THE SENSOR USING LIGHT SIGNALS
The invention relates to a lamp with a configurable presence detector that is configured by means of a light signal transmitted by a mobile device. In particular, the invention is directed to a lamp with an integrated presence detector that is configured by means of the light signal from a mobile device. The invention further comprises a correspondingly designed mobile device, a system and a corresponding method for configuration.
[0002] It is known to set up building technology systems, for example lighting systems, by means of mobile commissioning devices.
In lighting systems, inexpensive lights with an integrated presence detector (presence sensor) and an integrated daylight sensor are often used. Hotel corridors are an example of application. Presence detectors detect and report the presence of one or more people in their respective detection area. Motion detectors that work on the basis of a radar sensor are also used as presence detectors. The presence detector is often arranged with the illuminant under a common cover that is permeable to light and to the electromagnetic waves of the radar sensor. Setting parameters of the motion detector (configuration), for example a detection area, by setting rotary potentiometers and / or DIP switches, however, then requires opening and closing the cover using a suitable tool and is therefore complex.
US 2006/0125621 A1 shows a motion detector for a building surveillance system with a large number of motion detectors arranged in a distributed manner. After installation in the building, the motion detector is switched to a test operating mode and a person can test the motion detector in the test operating mode by executing suitable movements in the detection area of the motion detector and, if necessary, adjust adjustable parameters of the motion detector. A remote control device that is wirelessly connected to the motion detector is used to switch between test mode and normal mode, as well as to set the parameters of the motion detector.
The disadvantage of the arrangement shown in US 2006/0125621 Al of motion detector and wireless remote control device is that the wireless communication between the motion detector and wireless remote control device requires a special remote control device for the test mode and in particular a corresponding wireless receiver in each motion detector. This means that the complexity of the individual motion detector is high, so that every motion detector set up for this type of test operating mode causes corresponding costs. This is especially not feasible for applications in the low price segment.
[0006] The invention is therefore based on the object of realizing a simple and inexpensive configuration of a lamp equipped with a presence detector without the disadvantages described above.
The object is achieved with a lamp with a configurable presence detector, which has the features of independent claim 1, the mobile device, the corresponding system and method with the corresponding features.
A lamp according to the invention is equipped with a configurable presence detector and control electronics and is characterized in that the lamp comprises further receiving means. The receiving means is set up to receive a light signal with configuration information for a configuration of at least one parameter of the configurable presence detector, and the control electronics are designed to change the at least one parameter on the basis of the evaluated configuration information.
It is particularly advantageous if the lamp according to the invention is characterized in that the receiving means is a daylight sensor.
If an existing daylight sensor in the lamp is used as a receiving means for receiving the light signal with the configuration information, the lamp according to the invention can be set up without an additional special receiver and without an additional communication interface and thus inexpensively for the configuration of parameters of the presence detector. A particularly efficient use of existing hardware in the luminaire is thereby achieved without additional costs for a receiver and without additional space requirements for the receiver in the luminaire. The luminaire is particularly suitable for high-volume production at low cost and for retrofitting buildings without a lighting system with a control network.
[0011] The daylight sensor can also be integrated in the presence detector.
The lamp of one embodiment is characterized in that the presence detector is covered with a transparent cover, in particular together with the lamp of the lamp.
If the presence detector is covered with a transparent cover, as may be the case, for example, for a presence detector working on the radar principle, the transparent cover has to be removed to change parameters of the presence detector after installation To gain access to switches and / or potentiometers for setting (changing) parameters. The setting according to the invention by means of a light signal with the configuration information that can be transmitted through the transparent cover is particularly advantageous, since the cover does not have to be removed for the configuration and then reassembled, with a cover jointly covering all sensors and illuminants at the same time. This opens up significantly more options for the design of the luminaire without making it difficult to subsequently adapt parameters when commissioning the luminaire. The term “transparent cover” is to be understood in this context in such a way that the material of the cover is permeable to light at least in the visible light spectrum, possibly also in the adjacent and / or ultraviolet range, and is correspondingly low-attenuation.
The lamp of an advantageous embodiment is characterized in that the receiving means is arranged on an LED module, in particular on an LED circuit board.
Thus, a particularly simple structure of the lamp, as it is necessary and advantageous for the large-scale equipment of commercially used buildings, is achieved. The elements lighting means, in particular light emitting diode (LED), presence detector and receiving means in a common module enable a common installation in the building and especially if the module includes a transparent cover for LED, presence detector and daylight sensor, is a simple, cost-effective structure with a clear Form language in design and at the same time low costs for the subsequent change of the configuration according to the invention possible.
A preferred embodiment of the lamp is designed to adapt a sensor range of the presence detector (presence sensor), a detection area of the presence detector, for example with regard to the coverage diagram, elevation angle of the detection area, opening angle of the detection area, as configurable parameters. Alternatively or additionally, for example, an ambient light intensity, a sensor sensitivity of the presence detector, a switch-on threshold of a light in connection with the current daylight intensity, an afterglow period of the light or any combination of the mentioned parameters of the presence detector can be set on the basis of the configuration information.
The parameters of the presence detector are important for the function and reliability of the presence detector and influence the operating costs of a lighting system that works with presence detectors. By means of the procedure according to the invention and the lamp according to the invention, these essential parameters can be achieved without the effort to achieve each lamp.
It is possible to open, adjust settings by hand and then close the lamp again. This enables the system parameters of the presence detector to be adjusted in real time and a correspondingly optimized operation on the basis of changed environmental conditions is easy to implement.
The lamp according to the invention of a further embodiment is characterized in that the control electronics are set up to read data from the lamp, to generate a data signal with the data read from the lamp and to control a lamp in such a way that the data signal is sent by means of a modulation of light becomes.
It is thus possible with the lamp according to the invention by means of a device not only to configure parameters of the presence detector, but also, for example, to read out the current status of the presence detector and the currently set values of the parameters, for example for display on a screen of a mobile device. At the same time, the communication feedback channel implemented in this way from the luminaire to a mobile device enables the maintenance staff to be asked for authorization who want to find out or change the parameters of the presence detector. Access to the luminaire is only possible for authorized personnel without special safety devices such as lockable covers or additional bidirectional communication methods with additional transmitting and receiving devices having to be installed in the luminaire. Up-to-date security procedures for access to the lighting infrastructure are thus possible without the individual luminaire having to be equipped with a network interface, for example to an IP-based building network. This not only reduces the costs per luminaire used and additional connection technology in the network, but also increases security against unauthorized external access to the luminaire.
The technical problem is solved by a mobile device for configuring a lamp, the lamp having a configurable presence detector and the mobile device being characterized in that the mobile device is set up to generate configuration information for at least one parameter of the presence detector , and to send the configuration information to the luminaire by means of a light signal.
A preferred mobile device is characterized in that the mobile device is a mobile communication terminal, in particular a smartphone, a mobile computer or a configuration tool, for example a commissioning device.
The use of the mobile device for the configuration of parameters of the presence detector is particularly advantageous if the mobile device is based on a commercially available and thus inexpensive hardware. This is particularly the case for mobile radio devices with extended functionality (e.g. so-called smartphones) or mobile computers such as so-called tablets, on which the application-specific program runs in the form of an application program ("app") in order to implement the mobile device according to the invention.
The mobile device of an advantageous embodiment comprises a transmitting means that uses a screen lighting or a flash device of a camera of the mobile device to send the light signal to a receiving means of the lamp.
The use of a light signal to transmit the configuration information is particularly efficient when the mobile device already uses structural elements such as a flashlight diode of a camera or screen lighting as transmission means for the light signal for other primary tasks in the mobile device. This reduces the specific effort for implementing the invention. Specialized hardware with its own transmission means is not necessary since the transmission of configuration information known in advance with a limited range of values known in advance only requires a low data rate.
It is also advantageous if the mobile device has a receiving means, in particular a photo sensor or a camera sensor for receiving a further light signal, to
summarizes.
The mobile device can thus realize a wireless return channel from a lamp to the mobile device without additional effort, for example to receive read status data of the lamp and then present it to a user, or to receive an authentication query.
The technical problem is also achieved by a system for a configuration of lights comprising at least one light with a configurable presence detector according to one of the embodiments presented above and a mobile device according to one of the embodiments presented above.
The method according to the invention comprises a step of generating configuration information for the configuration of at least one parameter of the presence detector and converting the configuration information into a configuration signal by the mobile device. According to the invention, the method comprises further steps of sending the configuration signal by the mobile device by means of light, receiving the light signal by an integrated receiving means of the lamp and changing the at least one configurable parameter based on the received configuration signal by control electronics of the lamp.
[0029] Further goals, advantages, features and possible applications of the invention emerge from the following description of an exemplary embodiment with reference to the accompanying figures. All of the features described can form the subject matter of the invention defined in the appended claims, either individually or in combination. Show it

Figure 4 is a block diagram of a mobile device according to the invention.
In the figures, the same reference symbols show the same or similar features. A repeated explanation of the same reference symbols in the description is largely dispensed with in favor of a concise and clear representation.
In Figure 1, an embodiment of a lamp 1 according to the invention with an integrated presence detector 2 is shown. The lamp 1 comprises a plurality of lighting means 3.1, 3.2, ..., 3.X, in particular light diodes (LED), which are supplied with a suitable current by a ballast 10 (operating device, ballast), shown here as an LED driver circuit 8 become. In the case shown, the light output is controlled by a microcontroller 5, which in known lights essentially, but not exclusively, comprises a light control 7.
The light control controls the light output of the light sources 3.1, 3.2, ..., 3.x, based on the information determined by the presence detector 2 and a daylight sensor 4.
The daylight sensor 4 can be integrated in the presence detector 2 and can also be used to measure the ambient light and, based on this measurement, to activate or deactivate the presence detector 2 depending on a switch-on threshold of a light in connection with the current daylight intensity.
The daylight sensor 4 can, however, also be arranged outside the presence detector 2.
The daylight sensor 4 is a light-sensitive sensor that measures a light level of the
Practice light of the lamp 1 detected. In particular, the daylight sensor 4 detects how great the daylight level is. An output signal from the daylight sensor 4 is transmitted to the microcontroller 5 and in particular to the lighting control 7. The luminaire 1 can thus control a luminous flux of the lamps 3.1, 3.2, ..., 3.x as a function of an existing ambient light. According to the invention, the daylight sensor 4 also serves as a receiving means for a light signal with the configuration information. The inventive receiving means is implemented in the embodiment shown in Figure 1 by means of the daylight sensor 4 and a receiver 6 on the microcontroller 5, which receives the output signal of the daylight sensor 4 and detects, receives and evaluates a light signal contained therein with the configuration information. The configuration information extracted from the light signal by the receiver 6 is made available to the lighting control 7 in the exemplary embodiment shown. The light control 7 generates a control signal for the parameter control 9 of the presence detector 2 based on the configuration information. The parameter control 9 of the presence detector sets the values of at least one parameter of the presence detector 2 based on the control signal and thus based on the configuration information.
The presence detector 2 is an electronic sensor that detects movements in a detection area up to a certain, possibly adjustable sensor range and transmits a detected presence of one or more people in a presence detector signal to the light controller 7. The presence detector 2 can thus be used by the light control 7 to switch on the light 1 as required.
The lamp 1 shown further comprises a VLC modulator circuit 11 (VLC = visible light communication). The VLC modulator circuit 11 receives information from the luminaire control 7, for example status information, and modulates the LED current emitted by the LED driver circuit 8 with the status information and thus generates a further light signal with status information that is emitted by the lamps 3.1, 3.2, ... , 3.x is delivered. In this way, the lamp 1 can in particular transmit data about currently set values of the parameters of the presence detector 2, and also corresponding settings of the daylight sensor 4, the lamp control 7 and the ballast 10 by means of the further emitted light signal.
The presence detector 2 (presence sensor) can work as a motion detector actively with electromagnetic waves, for example according to the principle of Doppler radar, with ultrasound or passively based on the infrared radiation of the area around the lamp 1, combinations of these designs are also possible and advantageous for high-quality detection results.
The PIR sensor (English: Passive InfraRed) reacts in particular reliably to changes in angle when a person walks past the sensor. A Doppler radar reacts optimally when the distance between a person and the sensor changes. Motion detectors based on high-frequency electromagnetic waves penetrate glass, wood and lightweight construction walls as well as correspondingly permeable sensor covers and react to every movement, regardless of heat.
In order to enlarge the detection area and ensure that people are in a more sensitive so-called inner detection area, presence detectors 2 are ideally mounted on the ceiling and, as shown in FIG. 1, are integrated in ceiling-mounted lights 1.
When a movement is detected, the measurement of a time, which can be preset as a parameter, begins in the presence detector 2 or in the lighting control 7 until switching off.
The structural elements luminaire control 7, receiver 6, parameter control 9, VLC modulator 11 shown in FIG. 1 are also summarized under the term control electronics of the luminaire 1. Without deviating from the commissioning of the presence detector 2 according to the invention, the control electronics, for example also the parameter control, can largely be implemented in the microcontroller 5, its programming and external wiring.
Fig. 2 shows a lighting system with lights 1 and a mobile device 3 according to an embodiment of the invention. The lights 1 each include a presence detector 3 and a daylight sensor 4 and, in the case shown, are mounted on the ceiling of a hallway in a building. Especially in larger buildings, a corresponding control of the lighting by means of presence detectors and corresponding to the respective daylight is associated with cost advantages at the same time a corresponding control interface for a central control or for communication with an external commissioning device on each lamp 1 is associated with costs. From Figure 2 it can also be seen that the commissioning of each of the lights 1 is associated with opening a cover 13 of the mounted light 1 in order to change the setting of adjustable components 14, such as a rotary potentiometer and / or change the switch position of DIP- Switches 14, pulling or setting short-circuit bridges (jumpers) to configure at least one parameter of the presence detector 2. Access to adjustable components mounted on a common module carrier 15 of the lamp 1 in a lamp body 12 requires opening the transparent cover 13 in the illustrated case. The transparent cover 13 is translucent and at the same time covers the lighting means 3, for example LEDs, arranged on the same module carrier 15.
According to the invention, a mobile device 3 is used for picking the lamp 1 by means of VLC, that is to say communication via modulation of visible light. With the lighting means 3, the microcontroller 5, and the daylight sensor 4 (ALS), the lights 1 have suitable components for unidirectional and bidirectional communication by means of light. The mobile device 3 also has a camera 19 as a light-sensitive element, a flash light diode 20 and / or an illuminated screen 18 as light-emitting elements. The inventive transmission of the configuration information to the lights 1 by means of the mobile device 2 is thus possible without having to open the transparent, that is to say translucent, cover 13 of the light 1. Light in the visible wavelength range from around 380 to 780 nm can be used to transmit the light signal. The use of adjacent ultraviolet or infrared light spectra for the light signal is also possible and is included in the present description of the invention under the term light. The receiving means, in particular the daylight sensor 4 of the lamp 1 in FIG. 2, are designed to receive the light of a corresponding wavelength.
In Fig. 3 is a flow chart of a method for commissioning a lamp according to the invention with integrated presence detector 2 by means of a mobile device.
The method for configuring a lamp with a configurable presence detector by means of a mobile device begins with a first step S1 in which the mobile device 3 of the lamp 1 establishes a connection. As described above, this can be done by sending an initialization signal to the lamp 1 by means of light from the screen illumination or the flash.
In one embodiment of the invention, the lamp 1 is set up to request authentication information from the mobile device 3 by means of a further light signal, for example via a further modulated light signal emitted by the lighting means 3.1, ... 3.x. Such authentication information can be stored in a memory 22 of the mobile device 3, or queried by a user of the mobile device 3 via an input / output unit 22, which uses, for example, a touch-sensitive screen 18 or other input or output means of the mobile device 3 . This step S3 of the authentication of the mobile device 3 with respect to the light 1 makes it possible to restrict access to the light 1 to an authorized group, in particular also with graduated authorizations for adjusting the parameters of the presence detector 2.
If, in one embodiment of the lamp 1 according to the invention, the return channel for communication from the lamp 1 to the mobile device 3 is implemented, the lamp 1 can receive status data, for example available lamps 3.1, ..., 3.x, alternatively or additionally Data about the adjustable parameters, in particular currently set values of the parameters, possible
The setting ranges for the values of the parameters are transmitted to the mobile device 3 by means of VLC in a step S3.
In one embodiment of the invention, the transmitted status data of the lamp 1 can be presented to the user in a suitable form, for example on the screen 18, in a subsequent step S4.
In the following step S5, the user uses the mobile device 3 to create configuration information for at least one parameter of the presence detector 2. In a preferred embodiment, this configuration information includes at least one of the parameters sensor range of a presence detector 2, detection range of presence detector 2, ambient light intensity, and sensor sensitivity , a value for an adjustable switch-on threshold of the presence detector 2, an afterglow period for the lamps 3.1, ..., 3.x. This step S3 can take place interactively via a suitable user interface (GUI1) of a picking program on the mobile device 3.
According to the invention, in the subsequent step S6, the configuration information created by means of the mobile device 3 is then encoded and modulated onto a light signal. The configuration information can be encoded, for example, in a word with a length of 8 bits and then modulated onto a light signal emitted by the mobile device 3 from a flashing light diode 20. The light signal is sent from the mobile device 3 in a step S7.
In step S8, the light 2, in particular a daylight sensor 4, receives the light signal with the configuration information modulated on it. The microcontroller 5 of the light 1 can, for example, use a receiver 6 implemented in the microcontroller 5 and the daylight sensor 4 to implement a receiving means of the light for light signals with configuration information. Alternatively or additionally, the receiver can be designed as a separate functional unit in addition to the microcontroller 5, which receives an output signal from the daylight sensor 5.
The microcontroller 5 demodulates the light signal, evaluates the received configuration information in step S9 and generates suitable signals for storing parameters of the presence detector 2 on the basis of the received configuration information.
Fig. 4 shows a simple block diagram of a mobile device 3 according to an embodiment of the invention. The mobile device 2 is preferably a smartphone or mobile computer, which is represented in FIG. 4 with the usual, but not conclusively understood, function blocks. For example, the mobile device has a transceiver 21, a user interface 22 and an antenna 23, which enable communication via one or more cellular mobile radio networks according to one or more mobile radio standards. Only the units of the mobile device 3 that are essential for the implementation of the invention are discussed below.
According to the invention, the communication between the mobile device 3 and the lamp 2 is carried out by means of a light signal. For this purpose, the mobile device 3 can use at least one of the commonly available light-generating elements of a smartphone, in particular a flashlight diode 20, which is assigned to a camera 19 of the mobile device, or a screen illumination of the screen 18, as is also used to implement a flashlight function. It is also possible to use both the flashlight diode 20 and the screen lighting as a means of transmitting the light signal depending on the charge level of a battery 24 of the mobile device 3 and / or a determined ambient light intensity.
In a preferred embodiment of the invention, the further light signals from the lamp 1 to the mobile device 3 are received by means of the at least one camera 12 and demodulated using appropriately designed software and made available to the commissioning program.
The inventive use of the mobile device 3 for the configuration of the presence detector 2 is preferably carried out by executing the commissioning program (configuration program, app) stored in a memory 22 on a main processor 21 of the mobile device 3.
With reference to Figure 4 it can be seen that the inventive use of light signals for communication with the lamp 1 takes place using the camera 19, the flashlight 20 and the screen 18, and not on the mostly equally available, powerful communication means for Mobile radio, local radio networks (WLAN, WiFiTM), BluetoothTM, near-field communication (NFC) also use existing modules, although the units of the mobile device used as transmission means are not used according to their primary function.
Likewise, the use as a transmitter and receiver for communicating the configuration information to the lamp 1, the use of specially designed modules, for example VLC modules in a mobile commissioning device for lamps 1, is possible.
