Abstract

Example methods and apparatuses to provide lighting in appliances are disclosed. An example refrigerator includes a compartment disposed within the refrigerator having first and second opposite side walls, a movable component disposed in the compartment, the movable component having a front edge, a light pipe extending along the front edge of the movable component, and a first light source positioned at the first side wall to emit light into a first end of the light pipe.

First claim

What is claimed is:

1. A refrigerator comprising:
a compartment disposed within the refrigerator having first and second opposite side walls;
a movable component having a front edge and being moveably mounted within the compartment between a first position with the front edge extending between the first and second side walls with a first end adjacent the first side wall and a second position with the front edge translated in a direction parallel with the first side wall from the first position;
a light pipe externally fixed to and extending along the front edge of the movable component and having a first end adjacent the first side wall when the moveable component is in the first position; and
a first light source fixedly positioned on the first side wall and aligned with the first end to emit light into the first end of the light pipe when the moveable component is in the first position and displaced relative to the first end when the moveable component is in the second position such that the first light source is not aligned with the first end.

2. The refrigerator of claim 1 , wherein the compartment defines an opening, the first and second opposite side walls extending inward from the opening, the refrigerator further comprising:
a first light reflector having at least a portion thereof extending from the first side wall beyond the first light source and positioned between the first light source and opening.

3. The refrigerator of claim 2 , wherein at least the portion of the first light reflector further extends from the first side wall beyond the first end of the light pipe.

4. The refrigerator of claim 2 , wherein:
the portion of first light reflector is a first portion and defines a semicircular shape;
a second portion of the first light reflector is mounted to the movable component and defines a semicircular shape; and
the first and second portions align to define a generally circular connector surrounding the light source and at least the first end of the light pipe.

5. The refrigerator of claim 1 , wherein:
the moveable component includes an opaque trim piece defining the front edge thereof; and
the light pipe is mounted to an underside of the trim piece.

6. The refrigerator of claim 5 , wherein the trim piece defines a channel receiving the light pipe therein and surrounding a portion thereof disposed toward a top of the moveable component and along the front edge, a remaining portion thereof being exposed outside the channel.

7. The refrigerator of claim 6 , wherein the channel is complementary in shape to and contacts the light pipe along the portion of the light pipe surrounded by the channel.

8. The refrigerator of claim 6 , wherein a reflector extends along and in contact with the light pipe within the channel.

9. The refrigerator of claim 6 , further comprising a transparent substrate, wherein:
the trim piece extends around an outer edge of the transparent substrate.

10. The refrigerator of claim 9 , wherein the trim piece is a rectangular frame fully surrounding the transparent substrate.

11. The refrigerator of claim 1 , wherein the movable component is one of a shelf, a basket, or a bin.

12. The refrigerator of claim 1 , wherein the first end of the light pipe comprises at least one of a lens, a concave surface, a convex surface, a shiny surface or a flat surface.

13. The refrigerator of claim 1 , further comprising a second light module positioned at the second side wall to emit light into a second end of the light pipe adjacent thereto.

14. The refrigerator of claim 1 , further comprising a control system operatively connected to the first light source and programmed to disable the light source if the moveable component is moved to a position wherein the light pipe is unaligned with the light source.

15. The refrigerator of claim 1 , wherein the first light source is embedded in the first side wall, the first end of the light pipe contacting the first side wall.

16. The refrigerator of claim 1 , wherein:
the first side wall defines a support extending therefrom, the moveable component being positioned on the support; and
the lighting element is positioned forward of the support.

17. A movable component for use in an appliance, comprising:
a body defining a front edge extending laterally from a first side to a second side;
an opaque trim piece defining the front edge thereof and having an underside surface with a concave, arcuate profile;
a light pipe being cylindrical in profile, mounted directly to the underside surface of the trim piece within the concave, arcuate profile, and extending linearly along and external to a front edge of the body, the light pipe comprising:
a diffuser; and
first and second opposite ends respectively adjacent the first and second sides of the body, at least one of the first and second ends defining a light receiving surface positionable in an aligned manner with a light source of the appliance to receive light from the light source and in a displaced manner with respect to the light source with movement of the moveable component; and

a first light reflector at least partially circumferentially surrounding at least a forward portion of the light pipe and extending along a portion of the light pipe adjacent the first end and further extending laterally beyond the first end.

18. The component of claim 17 , wherein:
the trim piece is a drawer face; and
the underside of the trim piece is at least partially defined on a handle of the drawer face.

19. The component of claim 17 , wherein the body defines one of a shelf, a bin, or a basket.
