Problems solved by technology

By propagating light in the shelf with total internal reflection, the light can be distributed unhindered over the entire height and width of the interior, but only a small amount of light escapes from the shelf, so that despite the theoretically good light efficacy, Lighting efficiency is still poor

Embodiment Construction

[0028] figure 1 A view is shown of a refrigerator according to the invention comprising a body 1 and a door 2 connected to the body. The interior 3 is divided into compartments by shelves 4 for refrigerated items. The shelf 4 does not reach all the way to the front opening of the body 1 . In the area before the front edge of the shelf 4 (where the door bracket 5 fitted to the inside of the door engages when the door 2 is closed), on the side wall 6 of the body 1 are formed a plurality of paired The recesses are each sealed by a light-transmissive glass plate 7 . Each recess is used to accommodate a light-emitting diode, wherein the light-emitting diode is used to emit light toward the respective opposite side wall 6 and in the direction of the rear wall of the body 1 .

[0029] figure 2 A horizontal sectional view of the front region of the side wall 6 in which the recess 8 is formed is shown. The side wall 6 is provided in a known manner as a hollow body filled with ins...

Abstract

The invention relates to a carcass for a refrigeration appliance comprising an interior (3) surrounded by walls (6) and an open front, wherein a recess (8; 17) is formed in a wall (6) extending from the front of the carcass (1) in a depth direction of the carcass (1) and is closed by a light-impermeable pane (7), at least one light-emitting diode assembly (12) being accommodated in the recess. The carcass is characterized in that the pane (7) is at least locally transparent and a beam of light (13, 14) of the assembly (12) lies completely in the interior (3).

Description

technical field [0001] The invention relates to a refrigeration appliance, especially a domestic refrigerator, which includes a body and related interior lamps. The interior light fixtures are configured to meet a variety of very different needs. On the one hand, uniform illumination of the interior over the entire height of the body is necessary, even when the propagation of light in said interior is impaired by shelves and objects placed on said shelves; The lighting fixture must take up as little space as possible in the interior and also generate little heat. Background technique [0002] Powerful light-emitting diodes, especially white light-emitting diodes, which have been around for many years, offer an ideal solution to these requirements. Refrigerating appliances in which light-emitting diodes are used for interior lighting are disclosed, for example, in Patent Laid-open Application DE 298 14 243 U1. This patent publication discloses receiving light emitting diod...
