Lights On Appliance Door


The present invention relates generally to appliances, and more particularly to the lighting on an appliance door.

Normally, refrigeration appliances are fitted with interior lighting, which is switched on automatically when the door is opened.  Such interior lighting conventionally includes a single luminous element, positioned on a lateral inner wall of the body.

The luminous element illuminates items in its immediate environment very brightly, but items located at a further distance from the luminous element, or on compartment floors of the interior different from where the luminous element is arranged, are illuminated relatively poorly.  Illumination of the front region of the interior is difficult to satisfy in the existing design, especially when the compartment is fully loaded because items placed in the refrigerator can obscure the illumination from the interior luminous element.

This problem has not been addressed before because placing traditional incandescent lights at the front region of the interior takes up too much space to make the increase in visibility worthwhile.  Other designs place LEDs in slide-out shelves.  However, these have higher manufacture cost and cannot provide sufficient illumination to the front region of the interior.

There are existing designs that place a luminous element on a door, facing an interior.  However, the luminous element needs to be moved manually or automatically in order to direct its illumination to the front region of the interior.  Such designs increase the cost of manufacturing.  Furthermore, if a luminous element is only positioned on the door, the back region of the interior does not have enough illumination.

It would be desirable to have a simple and low cost means to provide sufficient illumination throughout the entire interior of a refrigeration appliance.


Figure 1 is an exemplary embodiment of the illumination in accordance with the present invention.

The present invention could apply to all appliances that have at least one door that...
