    专利说明:

    The present invention relates to a method for controlling a lighting device for indoor or outdoor areas, in which the color temperature of a light source of the time of day and / or the season is changed accordingly.
    Light, and in particular the color of light (i.e., the color temperature), is known to have a great influence on the mood of the person. Some hormones of the human body are responsible for this, namely melatonin (sleep hormone), which has a relaxing effect, cortisol (stress hormone) has an activating effect, serotonin (mood enhancer) and others. According to current knowledge, serotonin essentially promotes the awakening state.
    In detail, the influence of light color on hormone production can be summarized:
    Cold white natural light in the range of> 5500 K inhibits the production of melatonin and promotes the production of cortisol and serotonin.
    High color temperatures of> 5500 K thus have an activating effect on humans and low color temperatures of <3000 K have a relaxing, sleep-inducing effect.
    Central European sunlight has an average color temperature of approx. 5700 K over the course of the day.
    Even during the daytime it is often necessary to supplement the lighting in the interior with artificial light. Artificial light, which is produced for example by conventional incandescent lamps, has a much lower color temperature, is therefore much redder than natural light, which leads to problems. For a long time, therefore, there have been so-called daylight lamps on the market. Their color temperature is according to DIN EN 12.464 at 5,300 to 6,500 Kelvin. They are mainly used for lighting workplaces. In the medical field, daylight lamps are used in light therapy against winter depression.
    In the evening and at night, however, the daylight lamps inhibit melatonin production and thus prevent a natural relaxation and sleep process.
    Warm white light with less blue content, which does not inhibit melatonin production, is more pleasant and relaxing in this regard.
    Choosing the right color temperature especially for the home is therefore difficult and always a compromise.
    By using LEDs in the lighting, it is possible to control the color temperature. This can be done in a manner known per se either by mixing color LEDs (RGB) or more simply by mixing cold white and warm white LEDs. During the day, such lighting fixtures are typically driven so that the light color is cool white, while warm white light is emitted in the morning and evening or at night. In this way, positive effects on people can be achieved, which not only increase the subjective well-being, but also, for example, increase the performance.
    In principle, it is possible to carry out the control of the light color in such a way that the respectively existing daylight is detected via a light sensor in the outside area and the lighting fixture is activated as a function thereof. However, such a solution is expensive, since at least in an appropriate place an outdoor sensor must be installed and also a connection between this outdoor sensor and the lighting fixture must be made. The solution is also susceptible to errors, since the outdoor sensor can be disturbed by artificial light sources and in any case a strong dependence on the respective weather conditions is given.
    An alternative to this is a time-dependent control of the lighting fixture, as described for example in DE 20 2001 104 251 U. This provides a relatively easy way to adjust the color temperature to the daily routine. One problem, however, is the provision of the current time of day in order to actually be able to realize a lighting scheme adapted to the natural conditions. For this purpose, for example, the connection of all to be set up lighting devices with a corresponding computer system is required, or it is at least to provide a control device that provides a clock and the possibility of setting this clock.
    This requires an increased effort both in terms of equipment and in terms of maintenance.
    The solutions with built-in clocks without regular synchronization also have the problem of inaccuracy. Naturally, lighting devices develop heat, but this heat has a negative impact on the accuracy of the watch crystals. Especially with long-lived LED bulbs it is incomprehensible to the user why control times change over the years. Thus, such solutions must be regularly synchronized.
    It is not possible in this way to represent a light source that is unproblematic usable, but at the same time has the functionality of adjusting the light color.
    Another problem in this context is the fact that each official local time may deviate relatively strongly from the local astronomical time. Thus, the Central European time is about 33 degrees of longitude, which makes a difference of more than two hours in relation to the position of the sun.
    Object of the present invention is to avoid these disadvantages and to provide a solution that is simple and versatile. At the same time it should be possible to achieve a correct adaptation depending on the respective site.
    According to the invention, these objects are achieved in that a time signal is received via an RDS receiver.
    RDS (Radio Data System) is a widely used system for data transmission as an adjunct to the broadcasting of radio. Among other things transmitter information and a time signal are transmitted. For receiving RDS signals compact receiver units are commercially available at low cost. In many countries it is possible to receive radio broadcasts with RDS functionality practically everywhere.
    Thus, it is easily possible to receive a time signal without the need to adjust or monitor this. The installation effort can be kept low in particular by the fact that the
    Control unit that receives the time signal, near the bulb or can be performed integrated into the bulb.
    The solution according to the invention also offers the advantage that RDS signals can be received more easily and more stably than, for example, time signals at the wavelength of 77 kHz.
    The present invention now makes it possible to regulate the color temperature of the lighting fully automatically according to the natural light conditions. Depending on the time of the day, the season and the geographical location: When daylight shines, the lighting shines cold white, with sunset the light color changes to warm white; in the opposite direction again with sunrise.
    The optional "Office Mode" function makes it possible to partially override the natural light pattern, which means that, in addition to adapting to the natural gradient, it is sometimes possible to adapt to working hours or rest periods, for example during the adjustable working hours Another example of the use of the "office mode" is in the home area in the morning from 7:00 always warm white light to also use the activating function of the colder light.
    As the color temperature is reduced to warm white in the evening or at night, the positive effect of the cold white light during the day no longer disturbs the sleep rhythm.
    Apart from these deliberately chosen deviations, however, the most exact adaptation to the natural course of the light color remains upright.
    In a particularly preferred embodiment of the method according to the invention it is provided that the installation site of the illumination device is inferred via the RDS receiver. Since the RDS signal contains a transmitter identification, it can be deduced from the received frequencies, from which radio station the respective signal originates. Thus, an approximate position determination is possible whose accuracy can also be increased by evaluating two or more transmitters with RDS signal. Since a local inaccuracy of, for example, 50 km in east-west direction in Central Europe only makes a few minutes difference with respect to the position of the sun, in this way the local astronomical time can be determined with sufficient accuracy. The particular advantage of this embodiment is that the user does not have to make any special adjustment work with respect to the installation site of the lighting fixture.
    In addition to the light color, the intensity, i. the illuminance can be set time-dependent, which makes it possible to enhance the effects.
    The present invention also relates to a lighting device for interiors with at least one light source with variable color temperature and with a control unit to change the color temperature of the light source of the time of day accordingly.
    According to the invention, this illumination device is characterized in that the control unit is connected to an RDS receiver for determining the time.
    In particular, the RDS receiver is designed to detect the site of the illumination device. Thereby, a precise function can be achieved without the need for special adjustment work.
    A particularly simple embodiment variant of the invention is achieved if the control unit is integrated into the illumination device. Thus, for example, a floor lamp or other lighting fixture can be connected, erected or mounted in a conventional manner and brings the entire functionality of the adjustment of the light color, so that no additional measures are required.
    A further simplification can be achieved if the control unit is integrated in the lighting means. As a result, the invention can also be implemented in existing conventional lighting fixtures by using alternative, inventive lighting means.
    Another particularly advantageous embodiment of the invention provides that the control unit is equipped with a battery-buffered clock. In order to be able to control the correct light color already when switching on an illumination device according to the invention, it is necessary for the control device to also hold the respective current time signal in the switched-off state. If the lighting device is permanently powered, this is not a problem. However, if it is a lighting device with a built-in control unit, which is controlled by an external on / off switch, power is available only after switching on, in order to determine the current time via the RDS signal. In order to provide the correct color temperature immediately after switching on, a permanently running clock is kept in the control unit. This is corrected with the illumination device switched on via the RDS signal in order to avoid any inaccuracies.
    The simplest variant of the present invention works without any parameterization effort for the user.
    As an option, which is primarily intended for office or study, the luminaire or the illuminant may e.g. via a USB connection or similar and an associated software so that during definable working hours always cool white daylight appears. Twilight starts before the set working time or after the set working time with the same time as the natural sunrise or sunset would take (in Austria about 30 minutes).
    In a further consequence, the present invention will be explained in more detail with reference to the exemplary embodiments illustrated in the figures. 1 is a circuit diagram for explaining the present invention, and FIGS. 2 and 3 schematically.
    From a voltage source 1 mains voltage with 230 V, for example, is provided. In a power supply 2, a low voltage is generated to supply an LED driver 3, which drives the bulb 4.
    An RDS module, which includes an RDS receiver 5 and which is in communication with an antenna filter 6, communicates with a microcontroller unit 7, which drives the driver 3 via PWM signals to adjust the color temperature accordingly. The LED driver 3 thus represents a control unit for activating the illuminant 4. Transmitter information is also stored in the microcontroller unit 7, that is to say information about which transmitter locations which programs are broadcast on which frequencies. The sender identification received by the RDS module 5 may be inferred in relation to the frequency at the sender location since a program is typically broadcast by different transmitters at different frequencies.
    The microcontroller unit 7 is powered by a voltage converter 8 with energy, which may optionally include a backup battery to permanently power a system clock 9. The LED driver 3 together with RDS module 5 and microcontroller unit 7 thus represents a control unit 10 for controlling the light source 4.
    Fig. 2 shows schematically a variant in which a lighting device is equipped according to the invention.
    FIG. 3 shows a luminous means which completely brings along the solution according to the invention and can be used in a conventional illumination device.
    With 10 here summarizes the control unit shown above. In the embodiment of FIG. 2, the light sources 4 are combined in a light-emitting plate 11, which is docked to the control unit integrated in the light.
    In the embodiment of Fig. 3, the control unit are designated. In the embodiment of FIG. 2, the control unit 10 and the light-emitting plate 11 are arranged in the light source 4 itself.
    The present invention makes it possible to adapt the color temperature of lighting means exactly and simply to the physiological conditions and needs.
