Abstract

A light guide may be located behind an electronic display and have a number of LEDs located adjacent an edge thereof. A thermal plate may be placed adjacent to said plurality of LEDs and may be in conductive thermal communication therewith. The thermal plate may comprise a first portion located above the electronic display and a second portion located below the electronic display.

Claims

1. A display case assembly comprising:

a housing adapted to hold products; and

an access panel assembly comprising;

a transparent electronic display adapted to show an image on a front surface thereof;

a light guide positioned behind the transparent electronic display and having an edge;

a plurality of LEDs positioned adjacent to the edge of the light guide; and

a thermal plate positioned in close proximity to the plurality of LEDs.

2. The display case assembly of claim 1 wherein:

the thermal plate is in conductive thermal communication with the plurality of LEDs.

3. The display case assembly of claim 2 wherein:

the thermal plate comprises a first portion positioned above the plurality of LEDs.

4. The display case assembly of claim 3 wherein:

the thermal plate comprises a second portion positioned below the plurality of LEDs.

5. The display case assembly of claim 4 wherein:

the first and second portions of the thermal plate have substantially the same surface area.

6. The display case assembly of claim 5 wherein:

the first portion and the second portion of the thermal plate have substantially the same horizontal width as the transparent electronic display.

7. The display case assembly of claim 1 wherein:

the housing is a cooler adapted to hold bottled or otherwise packaged beverages.

8. The display case assembly of claim 7, wherein:

the access panel assembly serves as a door for the cooler.

9. The display case assembly of claim 1, further comprising:

a plurality of electronic devices mounted to the thermal plate.

10. The display case assembly of claim 9, wherein:

the plurality of electronic devices comprises;

a wireless transmitter/receiver;

a video player; and

an electronic storage device.

11. The display case assembly of claim 1, wherein:

the thermal plate comprises a first portion attached to the glass panel and a second portion attached to a substrate containing the plurality of LEDs, where the first portion is substantially perpendicular to the second portion.

12. The display case assembly of claim 1, wherein:

the plurality of LEDs and the light guide are adapted to illuminate both the transparent electronic display and the products located within the housing.

13. A display case adapted to hold products comprising:

a transparent display assembly comprising;

a transparent sheet;

a transparent electronic display positioned substantially parallel to and in front of said transparent sheet;

a light guide positioned between said transparent electronic display and said transparent sheet, wherein said light guide comprises an edge;

a plurality of LEDs positioned adjacent to the edge of said light guide; and

a thermal plate attached to said transparent sheet and positioned adjacent to said plurality of LEDs.

14. The transparent display assembly of claim 13 wherein:

the thermal plate comprises a top portion located above said transparent electronic display and a bottom portion located below said electronic display.

15. The transparent display assembly of claim 13 further comprising:

a front transparent sheet positioned in front of said electronic display.

16. The transparent display assembly of claim 13 wherein:

said thermal plate is in conductive thermal communication with said plurality of LEDs.

17. A display case assembly comprising:

a housing adapted to hold contents;

an access panel secured to said housing, said access panel adapted to be opened to access said contents;

a transparent electronic display secured within said access panel, said transparent electronic display being adapted to show an image while simultaneously enabling viewing of said contents in said housing through said transparent electronic display and the image being shown thereon;

a light source sub-structure placed adjacent to said transparent electronic display to aid in the showing of said image; and

a heat transfer element in relationship with said light source sub-structure to aid in dissipating heat from said light source.

18. The display case assembly of claim 17, wherein:

the housing is a cooler adapted to hold a number of bottled or otherwise packaged beverages.

19. The display case assembly of claim 17, wherein:

the access panel is a door.

20. The display case assembly of claim 17, wherein:

the heat transfer element is a plate.
