Abstract

Lighting units for refrigerator drawers and baskets are disclosed. An example refrigerator drawer assembly includes a shelf having a divider, the shelf defining at least a portion of a drawer compartment, first and second drawers disposed beneath the shelf, an elongated light source attached to a bottom surface of the divider, the elongated light source having a plurality of light-emitting diodes (LEDs) along the length of the elongated light source to provide a source of visible light for the first and second drawers.

First claim

What is claimed is:

1. A refrigerator drawer assembly comprising:
first and second drawers, each of the first and second drawers having an open top;
a shelf disposed above the first and second drawers, the shelf having a first portion that closes the open top of the first drawer, a second portion that closes the open top of the second drawer and a divider located between the first and second portions; and
an elongated light source attached to a bottom portion of the divider, the elongated light source having a plurality of light-emitting diodes (LEDs) along the length of the elongated light source to provide a source of visible light for the first and second drawers.

2. A refrigerator drawer assembly as defined in claim 1 , wherein the first drawer comprises a crisper drawer.

3. A refrigerator drawer assembly as defined in claim 1 , wherein the visible light improves visibility of items in the first drawer when the first drawer is in a closed position.

4. A refrigerator drawer assembly as defined in claim 1 , wherein the elongated light source comprises:
a printed circuit board to which the plurality of LEDs are mounted;
an enclosure into which the printed circuit board is mounted, the enclosure having a plurality of holes for respective ones of the plurality of LEDs; and
at least one of a light lens or a light guide into which the enclosure is mounted, the at least of the light lens or the light guide to diffuse the visible light emitted by the plurality of LEDs.

5. A refrigerator drawer assembly as defined in claim 1 , wherein the elongated light source is at least one of snapped, glued, screwed, or adhered to the bottom portion of the divider.

6. A refrigerator drawer assembly as defined in claim 1 , further comprising a user interface to enable a person to adjust mood lighting provided by the elongated light source.

7. A refrigerator drawer assembly as defined in claim 1 , wherein a first of the plurality of LEDs provides a first color of visible light, and wherein a second of the plurality of LEDs provides a second color of visible light.

8. A refrigerator drawer assembly as defined in claim 1 , wherein the elongated light source comprises first and second printed circuit boards, a first portion of the LEDs mounted to the first circuit board to provide visible light for the first drawer, and a second portion of the LEDs mounted to the second printed circuit board to provide visible light for the second drawer.

9. A refrigerator drawer assembly as defined in claim 1 , wherein the elongated light source comprises a twisted printed circuit board, the plurality of LEDs mounted to the twisted printed circuit board, a first portion of the LEDs to provide visible light for the first drawer, and a second portion of the LEDs to provide visible light for the second drawer.

10. A refrigerator drawer assembly as defined in claim 1 , wherein the elongated light source comprises a printed circuit board, a first portion of the LEDs mounted on a first side of the printed circuit board to provide visible light for the first drawer, and a second portion of the LEDs mounted on an opposite side of the printed circuit board to provide visible light for the second drawer.

11. An appliance comprising:
a cabinet;
a compartment located within the cabinet;
a first storage container located within the compartment, the first storage container having an open top;
a second storage container located within the compartment, the second storage container having an open top;
a shelf located within the compartment and above the first and second storage containers, the shelf having a first portion that closes the open top of the first storage container, a second portion that closes the open top of the second storage container and a divider located between the first and second portions; and
an elongated light source having a plurality of light-emitting elements along the length of the elongated light source, the light source disposed beneath the divider for providing a source of visible light for the first and second storage containers.

12. An appliance as defined in claim 11 , wherein the plurality of light emitting elements comprise respective ones of a plurality of light-emitting diodes (LEDs).

13. An appliance as defined in claim 11 , wherein the first storage container comprises a crisper drawer or a freezer basket.

14. An appliance as defined in claim 11 , wherein the visible light improves visibility of items in the first storage container when the first storage container is in a closed position.

15. An appliance as defined in claim 11 ,
wherein the compartment is divided into at least first and second portions defined at least partially by the elongated light source; and
wherein the first storage container is disposed in the first portion of the compartment and the second storage container is disposed in the second portion of the compartment.

16. An appliance as defined in claim 11 , wherein the elongated light source comprises:
a printed circuit board to which the plurality of light-emitting elements are mounted; and
an enclosure into which the printed circuit board is mounted, the enclosure having a plurality of openings for respective ones of the plurality of light-emitting elements.

17. An appliance as defined in claim 16 , further comprising at least one of a light lens or a light guide into which the enclosure is mounted, the at least of the light lens or the light guide to diffuse the visible light emitted by the plurality of light-emitting elements through respective ones of the plurality of openings.

18. An appliance as defined in claim 11 , wherein the elongated light source is at least one of snap affixed, glued, or adhered to the divider, the divider being located between the first storage container and the second storage container.

19. An appliance as defined in claim 11 , wherein the elongated light source is at least one of snapped, glued, screwed, or adhered to a bottom of the shelf.

20. An appliance as defined in claim 19 , wherein the shelf comprises glass that enables a person to view contents of the first storage container when the first storage container is in a closed position.
