    LIGHT WITH ENERGY RECOVERY CIRCUIT
    1. FIELD OF THE INVENTION
    The present invention relates to a luminaire comprising a light-emitting diode circuit, a power generation circuit and a load circuit.
    2. BACKGROUND
    In the prior art lighting systems are known which comprise a plurality of lights, which can be controlled in each case or in groups by means of a central control unit in order to adapt the lighting system to different lighting scenarios can. Such lights include facilities in which at least one control program can be stored and processed. Before such a lamp can be used, therefore, a corresponding control program must be transmitted to the lamp. Typically, this is done in the manufacture of the lamp.
    In practice, it has now been found that it is disadvantageous that no current or no version adapted to the installation version of a control software can be transmitted to a lamp and the lamp can not be put into operation (in particular parametrized), as long as the light is not yet connected to an external power supply. Although in the prior art it is known to connect a lamp to a separate external power supply for a short time, this is associated with a relatively high amount of time and thus costs.
    Based on this prior art, the present invention has the object to provide a lamp that can be at least partially put into operation without a connection to an external power supply. Furthermore, the object of the present invention is to provide a luminaire to which data (in particular current or adapted control software) can be transmitted without being connected to an external power supply.
    These and other objects, which will become apparent upon reading the following description or which will be recognized by those skilled in the art, are achieved by the subject matter of the independent claims. The dependent claims form the central idea of the present invention in a particularly advantageous manner on.
    3. DETAILED DESCRIPTION OF THE INVENTION
    A luminaire according to the invention comprises: at least one light-emitting diode circuit comprising at least one light-emitting diode (LED); at least one energy harvesting circuit having at least one electric energy storage device, wherein the energy harvesting circuit is connected to the light emitting diode circuit such that a photocurrent generated in the at least one light emitting diode upon light incidence is storable in the storage device of the energy harvesting circuit; at least one consumer circuit having at least one electrical load, wherein the consumer circuit is connected to the storage device of the energy recovery circuit such that with the electrical energy stored in the storage device, the electrical consumer is operable.
    Light-emitting diodes are semiconductor elements that convert light into electrical current by a photoelectric effect, and thereby can provide a so-called photocurrent. This photoelectric effect is used in particular for photodiodes and solar cells for generating electrical energy. In the case of all other semiconductor elements, this effect is undesirable per se, since this can adversely affect the behavior of the semiconductor elements. For this reason, semiconductor devices are typically arranged in opaque housings.
    One of the main ideas of the present invention is to use the photoelectric current of the intended for the lighting light emitting diode (s), which are usually housed in an at least partially transparent housing, and to store this in a storage device of the energy recovery circuit. Typically, luminaires are not put into operation immediately after their manufacture, so that the storage device for electrical energy can be charged by the incident after the manufacture of the lamp on the light emitting diode (s) light (for example, daylight or artificial light) and the existing light-emitting diodes continue as "Solar cells" can be used. In addition, there is also the possibility to selectively illuminate the lights after their production with daylight or artificial light to charge the storage device. The use of existing light emitting diodes for energy production eliminates additional components for energy production, resulting in a simplified structure and lower material and manufacturing costs result.
    As light-emitting diode (s) for the light-emitting diode circuit are essentially all common light emitting diodes into consideration, whereby organic light-emitting diodes (OLED) are suitable for use in a luminaire according to the invention.
    Preferably, the light-emitting diode circuit comprises a series of a plurality of series-connected LEDs, wherein preferably a plurality of these series-connected LEDs are connected in parallel. Typically, lights are provided with so-called "strings" of light emitting diodes (i.e., multiple series connected light emitting diodes). By incorporating a plurality of light-emitting diodes of the light-emitting diode circuit in the energy-generating circuit, it is possible to store more electrical energy within a certain period of time in the storage device of the energy-generating circuit. For example, a light emitting diode string with 24 light emitting diodes provides about 4 volts of voltage for typical office lighting of about 500 lux. The short-circuit current is about 460 nA, although this can be even higher at the maximum power point. Energy harvesting circuits known in the field of solar technology (for example the LTC3105 Linear Technology power generation circuit from Linear Technology) can already be operated from voltages of approximately 0.3 V.
    As a consumer of the consumer circuit are in particular Einrichtun gene / input means into consideration, which are necessary for commissioning the light or advantage (for example, a microcontroller, an interface for wireless communication, data storage modules, data processing modules, feedback, etc.).
    Advantageously, the light emitting diode circuit comprises a power supply and control module for the at least one light emitting diode or for the LEDs, wherein the connection between the light emitting diode circuit and the power generating circuit is advantageously separated by an electrical switch, which is controlled by the power supply and control module when the lamp is connected to an external power supply. Thereby, it is possible to separate the power generation circuit from the light emitting diode circuit during operation of the lamp, so that no voltage drops or the like can occur through the memory device or through the other devices of the power generation circuit.
    Advantageously, the energy harvesting circuit comprises a charge controller, which provides an adaptation of the energy harvesting circuit to different levels of photocurrents due to different light irradiations. Advantageously, the charge controller is a so-called maximum power point controller ("Maximum Powerpoint Controller"). Such energy recovery circuits are used, for example, in photovoltaic systems and are intended to ensure optimal "energy extraction" and storage.
    Advantageously, the storage device comprises an accumulator and / or a (charge) capacitor. Such storage devices are known in a variety of different embodiments, in particular with different storage capacities, so that an adaptation of the storage capacity of the storage device to a erfindungsge Permitted light, in particular to the intended consumers of the consumer circuit, can be done in a simple manner.
    A preferred consumer of the consumer circuit is a microcontroller, which is preferably designed as a so-called low-power microcontroller ("Ultra Low Power Micro Controller"). On such microcontrollers, for example, a control software, a luminaire address and / or control parameters for the lamp can be stored and / or processed. In addition, other non-volatile memory modules (such as flash RAM modules) can be provided to store the input, transmitted or processed data for later operation of the light.
    Furthermore, it is advantageous that a consumer of the consumer circuit is an interface for wireless communication, such as a Bluetooth interface, a ZigBee interface or a WLAN interface. Such an interface makes it possible to transmit control software and corresponding parameters in a simple manner to the luminaire, even if it has not yet been connected to an external power supply. Moreover, such an interface can also be used to read out data (for example type information on the luminaire, parameters of the luminaire, etc.) from the luminaire, in order to transmit these to a central control unit of a lighting system.
    Advantageously, said consumers of the consumer circuit are connected to the power supply and control module and are supplied by this with electrical energy as soon as the lamp is connected to an external power supply. As a result, an operation of the consumer of the consumer circuit can be ensured even if the lamp is connected to an external power supply.
    Further, it is advantageous if the lamp comprises at least one light emitting diode, which is adapted to receive and / or to transmit light signals ("Visible Light Communication"). Such (bidirectional) communication by means of light signals can be provided as an alternative to the above-mentioned interfaces for wireless communication or additionally thereto. In principle, a communication by means of light signals can already be provided by a single light-emitting diode. However, it is also possible, for example, to increase the accuracy or the transmission speed of the data transmission, to provide at least one arranged for receiving light signals photodiode.
    Preferably, the power supply and control module of the light emitting diode switching circuit, the at least one light emitting diode of the light emitting diode circuit and optionally the at least one photodiode for light communication with the storage device of the energy recovery circuit connected such that these for receiving and / or for sending of light signals are operable with the electrical energy stored in the memory device.
    Communication by means of light signals thus represents a further or additional possibility of transmitting data (for example operating parameters, a luminaire address, etc.) and / or control software to the luminaire. Such a data transmission can be effected by means of a light source (for example a pulsed laser light source), which is directed onto the light-emitting diode (s) or, as far as provided, on the photodiode configured for the reception of light signals.
    The invention further relates to a lighting system comprising at least one of the above-described lights.
    4. DESCRIPTION OF A PREFERRED EMBODIMENT
    Hereinafter, a detailed description of a preferred embodiment of a lamp according to the invention is given with reference to the accompanying figure. FIG. 1 shows a schematic circuit structure of a preferred embodiment of a luminaire according to the invention.
    FIG. 1 shows a schematic structure of a circuit arrangement for a luminaire according to the invention. The circuit arrangement in this case comprises a light-emitting diode circuit 100, a power generation circuit 200 and a load circuit 300.
    The light-emitting diode circuit 100 comprises a power supply and control module 110, a series of light-emitting diodes 120 connected in series (preferably at least one light-emitting diode string of a plurality of light-emitting diodes connected in series) and a short circuit switch 130.
    The light-emitting diode circuit 100 essentially corresponds to a circuit, as it is typically used for the operation of light-emitting diodes in a lamp. In operation, the power supply and control module 110 is connected to an external power supply (not shown) to thereby operate the light emitting diodes 120.
    The power generation circuit 200 includes a power generation circuit 210 (for example, a LTC3105 power generation circuit of Linear Technology).
    The energy recovery circuit 210 is connected to a storage device, in the present case in the form of a (charge) capacitor 220, connected. Furthermore, the power generation circuit 200 includes a breaker circuit 230 that disconnects the power generation circuit 200 from the light emitting diode circuit 100 when an external power supply is connected to the power supply and control module 110.
    As can be seen in Figure 1, the power generation circuit 200 is connected by means of lines 150 to the row of light-emitting diodes 120 of the light-emitting diode circuit 100. The power supply and control module 110 controls the breaker switch 230 such that the breaker switch 230 is closed when the light (ie, the power and control module 110) is not connected to an external power supply, and that the breaker switch 230 is open when the Lamp is connected to an external power supply. In the closed state of the breaker switch 230 thus resulting in the light-emitting diodes 120 photocurrent via the lines 150 in the power generation circuit 200, more precisely in the energy recovery circuit 210 and be stored by this in the capacitor 220.
    Advantageously, the energy recovery circuit 210 is regulated as a function of the light intensity, preferably via a so-called maximum power point control ("Maximum Powerpoint-ControN"). This makes it possible to adapt the energy extraction to different light intensities.
    The load circuit 300 includes in the embodiment shown a microcontroller 310, which is preferably a so-called low-power microcontroller ("Ultra Low Power Microcontroller").
    In the microcontroller 310 corresponding operating parameters can be stored or input or transmitted data processed. Furthermore, in the preferred embodiment shown, the consumer circuit 300 includes a wireless communication interface 320 (eg, a Bluetooth interface, ZigBee interface, or a WLAN interface) that may also be powered by the energy stored in the capacitor 220.
    As a result, it is thus possible to operate the microcontroller 310 and possibly also the interface 320 for wireless communication of the lamp even if it is not yet connected to an external power supply. Thus, appropriate inputs to the lamp can be made or data (for example, software updates, parameter data, luminaire addresses, etc.) are transmitted to the lamp, without having to be connected to an external power supply.
    The present invention thus provides a lamp that can be put into operation by the use of existing light-emitting diodes for energy or can be provided with a current control software, an adapted parameterization, etc., without causing visible design changes to the Lamp will be necessary.
    The present invention is not limited to the foregoing embodiment as long as it is encompassed by the subject matter of the following claims. For example, the number and arrangement of the features shown in FIG. 1 can be deviated from.
