Description of the Invention: [Technical Field] The present invention relates to a lighting device having at least one controller having at least one light emitting diode (LED), which is The color of at least one emitted light is varied by appropriate control. The invention further relates to a cooling device for at least one illuminating device. [Prior Art] The above illumination device is known, and for example, a diode can be provided. One of the light-emitting diodes is designed to emit green light, and the light-emitting diode is designed to emit red light. If such an illumination device is used, for example, to indicate the operational state of a device, for example, to display a state of charge, the red light-emitting diode is illuminated during charging, and the green light-emitting diode emits light. A variety of conventional cooling cabinets are considered as another prior art, an incandescent light bulb to illuminate. Illumination with incandescent bulbs in the cooling cabinet is inefficient and can cause undesirable heat losses in the area. Therefore, it will cause an inefficiency. The temperature of the cooling cabinet is usually set to a rotary potentiometer. For example, a count of 1 to 5 is set on the rotary potentiometer. The temperature set during the adjustment process is closely related to the cooling material in the cooling cabinet. If the cooling is interrupted, i.e., the cooling exceeds a specific temperature of one of the cooling materials, the material will be degraded and cause digestive problems after consumption. The light body and one of the light bodies are provided with the above two lights and the other one for the light of the battery. If it is used, it is not expected to be adjusted in the case of cooling, and the temperature of the substance is determined by the specific metering - 5 - 200926893 [Invention] The object of the present invention is therefore to provide a lighting device of the above form, in order to The risk of damage to the cooling material when the device is used in a cooling device can be minimized. The above object is achieved by a lighting device having the features of the first aspect of the patent application. According to another aspect of the invention, the invention also relates to a cooling device having at least one illumination device as described in claim 10 of the patent application. The present invention is based on the recognition that the above object can be achieved in an efficient manner by "the illumination device additionally has a temperature sensor", wherein the microcontroller is coupled to the temperature sensor and It is designed to vary the color of the light emitted by the illuminator based on the temperature measured by the at least one temperature sensor. Thus, different temperatures can be displayed in different white tones or colors. When using the illumination device of the present invention in a cooling device, a false color can be used to indicate that the food has expired in a virtual temperature adjustment. By using an illuminant having at least one light-emitting diode, the lossy power emitted by the illuminating device can be minimized, which in particular makes it possible to increase the efficiency in the cooling device. In a preferred embodiment, the illumination device of the present invention additionally includes a correspondence table coupled to the microcontroller and including the temperature measured by the at least one temperature sensor and the light emitted by the illuminator. The corresponding relationship of color. If such a correspondence table is not used, the microcontroller can also use a correspondence between the temperature measured by at least one temperature sensor and the color of the light emitted by the illuminator. Furthermore, it is particularly advantageous when the illumination device of the present invention has an interface for inputting a minimum- or maximum temperature enthalpy which forms a color spectrum of light that can be emitted by the illuminator. This interface can be, for example, an interface to a personal computer, i.e., a USB-interface or WLAN-interface in particular. Therefore, the color spectrum can be adjusted depending on the temperature range in the field of application. For example, 'different foods can be stored in different temperature ranges. With this measure, the individual temperature ranges can be adjusted. Preferably, the microcontroller is formed to control the illuminator to emit a flash of light at a temperature less than a minimum temperature 値 and/or greater than a maximum temperature 由 measured by at least one temperature sensor. Thus, the illumination device of the present invention may additionally have a memory 'in which a condition of less than a minimum chirp and/or greater than a maximum chirp is stored, so that, for example, when the current is interrupted, a flash can be additionally emitted by the illumination device, even during this period of time. This is also the case when the temperature is again within the rated range. Furthermore, this can be combined with a time measuring device such that the flash is only emitted when the time period when the temperature is outside the rated temperature range has exceeded a predefinable time period. By such measures and in a cooling device, the user can reliably detect the corrupted food before it is consumed. The illuminating body of the illuminating device of the present invention is preferably formed in the form of a strip. This results in a particularly space-saving installation, in particular in horizontal or vertical orientation. For example, when using the illumination device of the present invention in a cooling device (especially a cooling cabinet), each cooling surface is provided with an illuminant. The intensity of the light emitted by each illuminant at this time is only designed as 200926893. Let the associated cooling surface be illuminated. The illuminating device of the present invention preferably includes a power switch for turning the illuminating device on or off, in which case the power switch is constructed in particular as a door contact switch. In addition, according to a preferred embodiment, the illumination device can have a plurality of illuminants, each illuminator is provided with a specific temperature sensor, or at least two illuminators are provided with a common temperature sensor. In the first case, each cooling surface is monitored for a specific temperature when used in a cooling cabinet. In the second case, it is advantageous to have the same temperature on all of the cooling surfaces and the temperature sensor can be mounted in a position as central as possible. According to a second aspect, the invention relates to a cooling device having at least one illumination device as described above. In addition to the above described cooling cabinets, cooling counters, cooling boxes and coolant conveyors may also be included herein. Other advantageous embodiments will be described in the respective dependents of the scope of the patent application.

It is also possible to use at least one RGB-LED if LEDs that emit differently colored lights are not used. Here, the LEDs 22a to 22d form the illuminator 23. As the expert of this trip has revealed, the illuminator 23 can comprise a plurality of LEDs depending on the size of the item to be illuminated. According to an embodiment not shown, a plurality of illuminants 23 may be provided. At this time, each illuminant 23 may be provided with a specific temperature sensor 14, or a plurality of illuminants 23 may be provided with a common temperature sensing. 14.
