Description of the Invention: [Technical Field] The present invention relates to a lighting device having an illumination function that changes with time. The invention also relates to a method of operating a lighting device. [Prior Art] A lighting device usually has a function of changing with time, i.e., characteristics of light emitted by the lighting device, for example, color temperature, brightness, or color temperature of white light, which changes with time. This is done based on the application or the principle of randomness or circumstance. Some lighting devices have light-emitting diodes (LEDs) that emit multi-colors as a light source and thus emit almost any color of light, in which light is usually emitted in a continuously alternating color form . In order to control the lighting function, expensive control means are usually used, which for example can accurately adjust the desired color or brightness or display a color and/or brightness in which the order has been determined. In order to operate this control device and thus operate this illumination Q device', often expensive operating elements are often required. Moreover, the control device is continuously in an operational readiness state, which requires a high energy requirement. Retrofit lamps use traditional incandescent lamps, and there is no extra space in the retrofit lamp for expensive control and/or operating components. Such retrofit lamps are mostly used in illuminators which, by simple switching, are combined with a general current source that circulates or interrupts current to form illumination or interrupt illumination. Therefore, no more energy is available after the current required by the control device is interrupted. The above-mentioned lamps are known to align the desired color by modifying the small movement of the lamp itself - 201042193 or a rotary adjuster. However, such a disadvantage is not operative. This is because the adjuster is not easily adjusted due to its small size and the lamp is usually not easily accessible, which is caused, for example, by the configuration in the illuminator-or cover. SUMMARY OF THE INVENTION An object of the present invention is to provide a lighting device having a lighting function that changes with time, wherein the lighting function can be affected by a simple means. Moreover, the object of the present invention relating to the method of operation of the illumination device is achieved by providing a method by which the illumination function of the illumination device can be affected in a simple manner. The above-mentioned purpose of the lighting device is achieved by applying the features of the first item of the patent scope. Particularly advantageous arrangements are described in the respective sub-items of the scope of the patent application. " With components to detect the power supply voltage of the lighting device when the power supply voltage is interrupted for a short time and to affect the lighting function, the lighting function can be easily changed by, for example, Q by a majority of existing switches. By means of the switches, the supply voltage is interrupted in a short time (less than 2 seconds, preferably less than 1 second) without the need to provide separate operating elements. In order to prevent a reaction from occurring during random voltage fluctuations or voltage interruptions, the period of interruption must be longer than 25 milliseconds, preferably longer than 50 seconds, to trigger a change in illumination function. An illumination function that changes over time, if it includes sequentially illuminating in time with at least two different wavelengths, can achieve an illumination in a temporally different color. A lighting function that changes over time, if it includes at least two different color temperatures, -4- 201042193, sequentially emits white light in time, so that illumination can be realized in a temporally different color temperature. A dimmable illumination can be achieved if the illumination function that changes over time includes sequential illumination in time with at least two different intensities. It is appropriate when the illumination function can be switched from a temporally changing illumination function to a non-time-changing illumination function (especially an illumination function present at an interruption time point) by a short interruption of current supply. Thus, these states can be maintained when the desired illumination state (e.g., specific color, color temperature, and/or brightness) is reached. However, it is also possible to switch from any state to a certain state that does not exist at the time of triggering at the time of the triggering', for example, switching from a color to white light, or switching from a dimming state to a full-light state. Furthermore, it is appropriate when the illumination device is switched from a non-time-changing illumination function to a time-varying illumination function by a second short interruption of the current supply while the illumination function is fixed. Therefore, each time can be switched back to the original mode of operation or can be returned to another mode of operation that changes Q over time. It is advantageous when the illumination device comprises at least a short period of energy storage, in particular a capacitor. Here, during a brief interruption of the power supply voltage, this energy can be used in devices for power supply voltage detection and also in components that affect the illumination function. Suitably, the illumination device comprises at least one microprocessor. Thus, the detection of the power supply voltage can be performed and the illumination function can be controlled. Further, a led-retrofit lamp can usually use a microprocessor, so that the functions of the present invention can be integrated without much expense. 201042193 After a continuous interruption of the current supply for a long time, it may be advantageous to have the existing lighting function before the current supply interruption. Thus, when the lighting device is properly turned off, it is ensured that it is not necessary to readjust the desired lighting function (e.g., preferred color or brightness level) after turning it on. Here, each type of interruption is considered to be a longer interruption when it exceeds a predetermined limit 特别 (especially 2 seconds, preferably 1 second). Similarly, when the microprocessor no longer has enough energy to operate, then the interrupt at this time is considered a long-lasting interrupt, especially to determine that the supply voltage is re-on. 〇 The above object is achieved by a method of operating a lighting device in which an external operating element (especially a switch) is operated for a short period of time to interrupt the supply of current to affect the illumination function. Thus, the illumination function can be easily changed in the line to the illumination device by means of most of the existing switches, which can be used in a short time (ie, less than 2 seconds, preferably less than 1 second). The voltage supply is interrupted without the need to provide separate operating elements. It is advantageous when the illumination function changes over time, including at least two different wavelengths and Q illuminating sequentially in time. Thus, different colors of illumination can be realized with simple components. Moreover, it is advantageous when the illumination function that changes over time includes sequentially illuminating in time with at least two different intensities. Thus, a dimmable illumination can be achieved. In another advantageous form of the invention, it is advantageous when the illumination function changes over time comprises sequentially emitting white light in time with at least two different color temperatures. Thus, the color temperature of the illumination can be adjusted with simple components. It is appropriate when the lighting function can be switched from a lighting function that changes from 201042193 to a lighting function that does not change with time (especially the lighting function that exists at the time of interruption) by a short interruption of the current supply. Thus, these states can be maintained when the desired illumination state (e.g., specific color and/or brightness) is achieved. However, it is also possible to switch from any state to a certain state that does not exist at the time of the trigger at the time of the trigger, for example, switching from a color light to white light, or switching from a dimming state to a full light state. The invention will be described in detail below in accordance with an embodiment. [Embodiment] FIG. 1 shows an LED-retrofit lamp 1 as an example of the illumination device 1 of the present invention. Such a lighting device 1 is preferably used as a conventional incandescent lamp and can therefore be provided with a conventional base 2, here a so-called E27-bolt base 2, and a light bulb 3. In such a lighting device 1, the light-emitting diode 4 is used as a light source. The present embodiment relates to a so-called RGB-diode 4, i.e., which produces light in the range of red (R), green (G) and blue (B) and any combination thereof, in particular white light. Q Such a retrofit lamp 1 can be used in so-called effective illumination, i.e., it illuminates in a specific color or can be permanently color-changed to create an atmosphere that is pleasant to the operator. In order to control the LED 4, a microprocessor 5 is provided which supplies a voltage by means of an AC/DC converter 6. Further, the input terminal 7 of the microprocessor 5 is connected to the power supply voltage UN «tz. The AC/DC-converter 6 includes a capacitor 8 which is used to smooth the output voltage Udc during normal operation. Fig. 2 is a graph showing the relationship between the time curve of the power supply voltage UN6tz of the illumination device 1, the output voltage Uk of the AC/DC-converter 6, and the state of the illumination function 201042193 with respect to time t. Here, the color conversion operation of the LED 4 is represented by the function F1, that is, it is an operation mode in which the color emitted by the illumination device 1 is based on a preset process by the respective colors of the RGB-LED 4. The intensity changes and changes. As shown in Fig. 2, if the power supply voltage Unmz is interrupted for a short time, the capacitor 8 of the AC/DC-converter 6 is used as the energy storage device 6 and thus the microprocessor 5 is additionally supplied with the voltage Ud. . And can continue to operate. Conversely, LED 4 is not driven immediately to save energy. Thus, the capacitor 8 can be designed with a smaller capacity, or the microprocessor 5 can be operated for a longer period of time at a predetermined capacity. After the time U (where < tx <tmai<), the power supply voltage UNelz is detected again on the output terminal 7, so that the microprocessor 5 can recognize that there is only a short time voltage interruption and it is expected that the function change is successful. Can F2. This function F2 indicates that the lighting device 1 continues to illuminate in that color, whereby the lighting device 1 can continue to operate at the point in time when the power supply voltage U^lz is interrupted. U If the supply voltage Un... is reinterrupted at time u, the microprocessor 5 switches the function back to function F1, i.e., the lamp 1 is again operated in the mode of color conversion operation. In order to prevent switching of the illumination function during short-term power supply voltage fluctuations or malfunctions, a minimum time tmin must be determined to identify the voluntary interruption. A time greater than 25 milliseconds (especially better than 50 milliseconds) has been shown to be advantageous. It is necessary to select a time tma;i, so that the operator can perform double switching without problems on the one hand, and on the other hand, the capacitance of the capacitor 8 does not have to be too large, otherwise the space problem will be caused and the manufacturing cost will be changed. Big. 201042193 Figure 3 shows the various dimensions of Figure 2 in the following cases: for example, the power supply voltage Un... is continuously interrupted by an optical switch or due to a current failure. After the end of time tmn, the output voltage Udc of the converter 6 is interrupted and the microprocessor 5 adjusts the operation. After the supply voltage Un〃z and the converter voltage Udc are applied again, the current is supplied to 11) 4 and the operation is performed again with the previously completed illumination function. Of course, other embodiments of the invention are also possible. Therefore, in particular, there may be another light function that changes with time to replace the color appearance. Here, for example, a change in strength can also be performed. It is also possible to issue a separate color at a predetermined time to replace the continuous color appearance' to suddenly switch to a distinctly different color, which allows the operator to reliably select a fully defined color. It is also possible to switch from one color to the next color or to switch between two different color appearances by interrupting the current signal for a short time, each color appearance being different, for example, due to the rate of color change. - Again, the existing optical function in the transition Q state can be re-driven after the power supply voltage has been interrupted for a longer period of time. The configuration of the lighting device 1 can also be different from the above. Therefore, when the advantages of the present invention function particularly well, the lighting device 1 is not necessarily constructed by modifying the lamp 1. Also, of course, other pedestal-and/or light bulb forms may be used, wherein LEDs 4' of different colors (e.g., amber or white) may also be used and, for example, an organic light-emitting diode may also be used. Further, other light sources (e.g., discharge lamps) may be used instead of the LEDs 4, but the LEDs may be particularly well used in the illumination device of the present invention due to rapid reaction characteristics and small current loss. 201042193 [Simple Description of the Drawings] Fig. 1 shows an LED-modified lamp as an example of the lighting device of the present invention.
