Definitions
- the invention relates to a refrigerator and / or freezer with a cooled interior, which comprises a nischenformigen interior section.
- nischenformigen interior sections has been achieved with directly attached bulbs, for example, arranged on the top cover LEDs.
- the illumination and light distribution was in this solution by the position and radiation characteristics of the bulbs. Often fall from Verbauungshuntn on the one hand and illumination reasons on the other optimal positioning of the bulbs, such as the LED board not together. There has to be a compromise.
- the object of the invention is to achieve an optimal and uniform illumination of the nicheformigen interior section and at the same time to achieve a favorable from Verbauungshuntn positioning of the light source.
- a refrigerator and / or freezer with a cooled interior which includes a nicheformigen interior section, wherein the device is a lamp and one between the light source and a light source arranged on a wall surface of the interior portion, and wherein the light source and the light conductor are arranged such that the light conductor discharges the light introduced from the light source into the interior space portion.
- the optical waveguide can thus guide the light, starting from the illuminant, to another location, which is more favorable for the illumination of the niche-shaped interior portion.
- the comparatively larger light source can be attached to a favorable Schwarzbauungshuntn position, while the comparatively smaller light guide can lead to the point that is most favorable for illumination, but at the possibly little space is available and the may be difficult to access, for example during maintenance or wiring.
- the device has at least two light guides, which are in communication with the light source and are arranged so that they emit the light introduced by the light source at different locations in the interior section. With several light guides, an initiation in several places is possible to achieve an even more uniform illumination.
- an optical element which influences the light emission characteristic is present at the interior-side end of the light guide.
- Examples include lenses and the like.
- the luminous means has one or more individual light sources, the light sources preferably comprising LEDs, OLEDs or lasers. These light sources can be arranged, for example, on a circuit board or distributed on a plurality of circuit boards.
- the Illuminant in the sense of the claim is thus to be understood as the sum of the individual light sources assigned to the light guides.
- Each of the individual light sources or groups of individual light sources may be associated with different light guides.
- the light sources can also be arranged at remote locations.
- the light sources are designed and arranged such that they introduce light of different intensity into the different light guides.
- the light guides are designed differently and preferably have different lengths.
- at least two of the light guides differ in length, thickness and / or conduction characteristic. During operation of the device can therefore be achieved that the exiting from the individual light guides light intensities are the same despite different design of the light guide.
- a corresponding operating method is also encompassed by the present inventive concept.
- the cross section of the light guides can be round or square. Other cross sections are conceivable. It is also conceivable to use flexible light guides in order to achieve greater flexibility in installation. To increase the efficiency of the optical waveguides, it is also possible to provide a mirroring of the lateral surfaces.
- the luminous means is arranged on a boundary wall of the interior portion, for example on the outside of the boundary wall, wherein the boundary wall may be a portion of the inner container. In one embodiment, it is provided that the luminous means is arranged asymmetrically with respect to the boundary surface of the interior section corresponding to the boundary wall. If the boundary wall is formed, for example, by a flat section of the inner container, then the illuminant in this embodiment would not lie in the center of the portion but, for example, in its edge region. If no light guide were present, the interior portion would not be uniformly illuminated in this embodiment, since the light irradiation would come from a corner region of the boundary surfaces.
- the lighting means is arranged outside the interior and preferably foamed.
- the interior portion is a drawer such as a drawer, a recess formed by a molding of the inner container or at least partially separated from the remaining interior storage compartment.
- the device is a household cooling device with preferably a refrigerant circuit, preferably a refrigerator and freezer combination device.
- the respective interior portion may be formed by a portion of the cooling portion or the freezing portion, for example, by a arranged in the refrigerator or freezer drawer.
- Figure 1 is a perspective view of limiting wall parts of a niche in the interior of a device according to the invention obliquely from below;
- Figure 2 is a perspective view of the same wall parts obliquely from above;
- FIG. 3 a frontal view of the same wall parts
- Figure 4 a side view of the same wall parts
- Figure 5 a plan view of the same wall parts.
- the niche is generally designated by the reference numeral 1. It is bounded by three side walls 2a, 2b and 2c and a ceiling 3.
- the side walls 2a, 2b and 2c may be parts of the inner container.
- the ceiling 3 can be represented for example by an intermediate floor within the device.
- the niche 1 is formed to receive a drawer, not shown in the figure, or another dispensing unit.
- the niche 1 has a bottom, not shown in the figure, which can also be represented by, for example, an intermediate floor within the device.
- this niche 1 should be lit or staged as much as possible.
- the niche can be illuminated from outside or from a wall of the niche 1, the latter being preferable for complete and uniform illumination. It is necessary to arrange on one of the side walls 2a, 2b and 2c or on the ceiling 3, a light source that illuminates the niche. In the interest of a uniform illumination, it may be advantageous here to arrange the light source on the ceiling 3, especially if, for example, a drawer or other output unit are arranged in the niche 1, which could hinder light from the side or from below.
- the illuminant 5 for the illumination of the niche 1 does not attach directly to the point of the ceiling 3, at which the light is to be delivered to the niche 1, but at another point at which a Verbau and a wiring in view of the space limited by the components 4 space is the cheapest. It is conceivable arrangement in a foreclosed area, which is useful in terms of safety and manufacturing technology. Starting from the light source 5, the light is then guided by means of two light guides 6a and 6b to specific locations of the ceiling 3, from which, starting a light introduction into the niche 1 is particularly favorable. On the basis of this principle, it is also possible to illuminate areas which are difficult to access despite the restricted space available for the light source.
- symmetrical light distribution in the niche 1 can be generated despite asymmetrical arrangement of the luminous means 5 which is conditional on space.
- the asymmetrical positions of the light source 5 for Illumination environment, ie, the niche 1 are distributed symmetrically in the illumination environment by the geometry of the light guides 6a and 6b.
- the lighting means 5 is a printed circuit board with several LEDs arranged thereon as individual light sources. Different LEDs of the luminous means 5 are assigned to the different optical waveguides 6a and 6b in order to achieve a different irradiation characteristic, for example to be able to irradiate light of different intensities into the two optical waveguides 6a and 6b.
- the light sources which couple into the respective optical fibers 6a and 6b, electronically scaled or weighted so that the exiting light intensities at the end of the optical fibers 6a and 6b, despite different geometries and in particular lengths are equal.
- An optic 7a or 7b at the end of the optical fibers 6a and 6b generates a symmetrical light distribution despite fundamentally different emission characteristics at the light exit of the optical fibers 6a and 6b, which may be caused by different geometries and lengths of the optical fibers and by the different light exit positions in the niche 1 ,
