  • Technical area
  • The The present invention relates to a lighting device with at least one luminaire with at least one LED and a microcontroller, wherein the microcontroller is designed by appropriate control the color of the light to be emitted by the at least one lamp to vary. It also concerns a cooling device with at least one such illumination device.
  • State of the art
  • such Lighting devices are known, for example, two LEDs can be provided one of which is laid out green To emit light and the other is designed to emit red light. If such a lighting device is used to, for example, the Operating status of a device display, for example, a loading device for a Battery, it lights up while Charging the red LED. When the charging process is finished, it lights up the green LED.
  • When Another state of the art is to call conventional refrigerators, which is a light bulb for Use lighting.
  • The Illumination of a refrigerator with a light bulb is inefficient and generates just in the area in which chilled should be, unwanted Waste heat. This results in an undesirable Low efficiency. The temperature of a refrigerator usually becomes set by means of a rotary potentiometer, on the example Numerical values from 1 to 5 are given. The temperature that is up when setting a particular numerical value is very much depends on, how much chilled goods in the fridge located. Will the cooling interrupted, i. the temperature of the chilled goods exceeds a certain, kühlgutspezifische Temperature, the refrigerated goods can already spoiled. Its enjoyment can cause digestive problems to lead.
  • Presentation of the invention
  • Of the The present invention is therefore based on the object, a generic lighting device in such a way that when used in a cooling device the risk of spoiling refrigerated goods is minimized.
  • These Task is solved by a lighting device having the features of claim 1. According to one another aspect of the present invention further relates to this a cooling device with at least one such illumination device according to claim 10th
  • Of the The present invention is based on the finding that these Problem can be solved in an excellent way that the lighting device further comprising a temperature sensor, wherein the microcontroller coupled with the temperature sensor and is designed the color of the light to be emitted by the luminaire in dependence on one of the at least to vary a temperature sensor measured temperature. there can different Temperatures can be displayed with different shades of white or colors. When using a lighting device according to the invention in a cooling device can be false colors used to set the wrong temperature setting Food expired appear.
  • By the use of a lamp with at least one LED is also minimizes the power dissipated by the illumination device, the efficiency, especially when used in a cooling device, increases.
  • In a preferred embodiment comprises a lighting device according to the invention Furthermore, an allocation table coupled to the microcontroller that is an assignment of the at least one temperature sensor measured temperature and color of the lamp to be dispensed by the lamp Includes light. Instead of a mapping table or in addition can also a formulaic assignment from the at least one temperature sensor measured temperature and Color of the light to be emitted by the light through the microcontroller be made.
  • Especially preferably has a lighting device according to the invention continue to interface on to a minimum and a maximum Enter temperature value between which the color spectrum of the light of aufbaren light is aufzuspannen. This interface can For example, be an interface to a PC, ie in particular a USB or WLAN interface. Leave it the color spectrum matches the temperature range in the field of application to adjust. For example, different foods store in different temperature ranges. Through this measure can be adapted to the respective temperature range become.
  • Preferably, the microcontroller is designed to control the lamp for emitting flashing light at a temperature measured by the at least one temperature sensor below the mini paint the temperature value and / or above the maximum temperature value. In this context, a lighting device according to the invention, moreover, have a memory in which falls below the minimum temperature and / or exceeding the maximum temperature is stored, so that, for example, in a power failure of the lighting device flashing light is emitted, although in the meantime, the temperature again Target range is. Furthermore, this can be combined with a time measuring device, so that the flashing light is emitted only if the time duration in which a temperature was outside the setpoint temperature range has exceeded a predefinable time duration. By this measure and use in a cooling device, a user can be very reliably prevented from eating spoiled food.
  • Prefers is the lamp of a lighting device according to the invention formed strip-shaped. this makes possible an extremely space saving accommodation, in particular, a mounting in horizontal or vertical direction is preferred. For example, at Use of a lighting device according to the invention in a cooling device, especially a refrigerator, per refrigerated compartment a luminaire may be provided, the luminous intensity of which is to be delivered by each luminaire Light only needs to be designed so high that the associated refrigerated compartment is illuminated.
  • Prefers comprises a lighting device according to the invention furthermore a power switch for switching the lighting device on and off, this particular as a door contact switch accomplished can be.
  • According to one preferred embodiment further provided that it has a plurality of lights, wherein Each luminaire has its own or at least two luminaires a common one Temperature sensor is assigned. In the first variant can at Use in, for example, a refrigerator each refrigerator compartment own temperature can be assigned and monitored. The second Variant is advantageous if all cooling compartments have the same temperature allowed to and the temperature sensor can be mounted in as central a position as possible is.
  • The The present invention relates to a second aspect of a Cooler, the at least one illumination device according to one of the preceding claims having. In addition to the already mentioned fridge here are still refrigerated counters, coolers and refrigerated goods transporter.
  • Further preferred embodiments emerge from the dependent claims.
  • Short description of the drawing (s)
  • in the The following will now be an embodiment of a lighting device according to the invention with reference to the attached Drawings closer described. Show it:
