Abstract

A solar powered display assembly and systems and methods for the same are provided. An electronic display portion comprising an electronic display within a housing is secured to a structural framework at a position elevated above a ground surface. A solar energy harvesting device is connected to the structure framework at a position above, and spaced apart from, said electronic display portion, wherein said solar energy harvesting device is electrically connected to the electronic display portion. A bulk energy storage device is located below the electronic display portion. A footprint of the solar energy harvesting device is smaller than footprints for the electronic display portion and bulk energy storage device.

First claim

What is claimed is:

1. A display assembly comprising:
a structural framework configured for attachment to a ground surface;
an electronic display portion comprising one or more electronic displays within one or more housings secured to said structural framework at a position elevated above said ground surface;
a solar energy harvesting portion comprising solar cells connected to said structure framework such that said solar energy harvesting portion is located above, and spaced apart from, said electronic display portion; and
a bulk energy storage portion comprising a housing and one or more batteries located below said electronic display portion;
wherein said solar energy harvesting portion has a first footprint, said electronic display portion has a second footprint which is smaller than said first footprint, and said bulk energy storage portion comprises a third footprint which is smaller than said first footprint.

2. The display assembly of claim 1 wherein:
said solar energy harvesting portion comprises a first panel area with a first number of said solar cells and a second panel area with a second number of said solar cells, wherein said first and second panel areas are positioned adjacent to one another in a manner forming an obtuse angle between upper surfaces of said first and second panel areas.

3. The display assembly of claim 1 wherein:
one or more electric vehicle chargers are attached to said structural framework.

4. The display assembly of claim 3 wherein:
each of said electric vehicle chargers are electrically connected to said one or more batteries;
said solar cells are electrically connected to said one or more electronic displays and said one or more batteries.

5. The display assembly of claim 4 wherein:
said one or more electronic displays are configured for electrical connection to an electrical grid; and
said one or more batteries are configured for electrical connection to said electrical grid.

6. The display assembly of claim 5 further comprising:
one or more electronic components for controlling power supply to said one or more electronic displays from said electrical grid, said one or more batteries, and said solar energy harvesting portion; and
one or more electronic components for operating the one or more electronic displays.

7. The display assembly of claim 6 wherein:
said solar energy harvesting portion is configured to produce direct current (“DC”) power;
said one or more electronic displays are configured to accept power from the solar energy harvesting portion in DC power form; and
said one or more electronic displays are configured to accept power from the electrical grid in alternating current form.

8. The display assembly of claim 1 wherein:
said bulk energy storage portion is physically separate from the structural framework; and
said bulk energy storage portion is electrically connected to said solar energy harvesting portion and said electronic display portion.

9. The display assembly of claim 8 wherein:
said structural framework comprises a first support member and a second support member; and
said first and second support members are located on either side of said bulk energy storage portion.

10. The display assembly of claim 1 wherein:
said bulk energy storage portion is physically connected to said structural framework.

11. The display assembly of claim 1 wherein:
said ground surface comprises a sidewalk.

12. The display assembly of claim 1 further comprising:
one or more open loop pathways for ambient air extending within said one or more housings of said electronic display portion behind said one or more electronic displays.

13. The display assembly of claim 12 further comprising:
one or more closed loop airflow pathways for circulating gas extending within said housing about said one or more electronic displays.

14. The display assembly of claim 13 wherein:
said electronic display portion comprises a first and second electronic display placed in a back-to-back arrangement; and
said one or more closed loop airflow pathways are common to said first and second electronic displays.

15. The display assembly of claim 1 wherein:
each of said one or more electronic displays comprises a liquid crystal display.

16. A display assembly comprising:
a structural framework configured for attachment to a ground surface;
an electronic display portion comprising thermal management components and at least one electronic display within a housing secured to said structural framework at a position elevated above said ground surface;
a solar energy harvesting portion comprising a number of solar cells provided on one or more panels connected to said structure framework such that said solar energy harvesting device is located above, and spaced apart from, said electronic display portion in a canopy arrangement, wherein said solar energy harvesting device is electrically connected to said at least one electronic display and said thermal management components;
a bulk energy storage portion comprising one or more batteries within a housing located below said electronic display portion, wherein said batteries are electrically connected to said solar cells, said at least one electronic display, and said thermal management components;
an electric vehicle charger attached to said structural framework and electrically connected to an electrical grid and said batteries; and
a power management controller electrically interposed between, and configured to selectively source power from, said electrical grid, said solar cells, and said batteries for supplying power to said electric vehicle charger, said thermal management components, and said at least one electronic display;
wherein said solar energy harvesting portion has a first footprint, said electronic display portion has a second footprint which is smaller than said first footprint, and said bulk energy storage portion has a third footprint which is smaller than said first footprint.

17. The display assembly of claim 16 wherein:
said thermal management components comprise at least one open loop airflow pathway extending behind said at least one electronic display and fans configured to move ambient air through said at least one open loop airflow pathway when activated.

18. The display assembly of claim 17 wherein:
the structural framework comprises at least two support members extending on either side of said bulk energy storage portion such that said bulk energy storage portion is physically separate from said electronic display portion and said solar energy harvesting portion.

19. The display assembly of claim 17 further comprising:
at least one item of street furniture physically connected to said structural framework.

20. A display assembly comprising:
a structural framework comprising a number of support members configured for attachment to a ground surface;
an electronic display portion comprising at least one electronic display and at least one fan within a housing secured to a mid-portion of said structural framework such that said electronic display portion is elevated above said ground surface;
a solar energy harvesting device connected to an upper portion of said structure framework such that said solar energy harvesting device is located above, and spaced apart from, said electronic display portion to act as a shelter for the electronic display portion and a surrounding area, wherein said solar energy harvesting device is electrically connected to said dis
