Definitions

  • Patent Application Serial No. 60/887,075 filed on January 29, 2007 and entitled "Power Supply In Conduit” in the name of Matthew Ward and David Main, which is hereby incorporated by reference in its entirety.
  • Embodiments disclosed herein generally relate to power supply units. More specifically, embodiments disclosed herein relate to an improved method and apparatus for supplying power to an externally powered device, such as a light emitting apparatus or a light emitting system.
  • an externally powered device such as a light emitting apparatus or a light emitting system.
  • Display units for entertainment, architectural, and advertising purposes have commonly been constructed from numbers of light emitting elements, such as light emitting diodes (“LEDs”) or incandescent lamps mounted onto flat panels.
  • the light emitting elements may be selectively turned on and off to create patterns, graphics, and video displays for both informational and aesthetic purposes. It is well known to construct these displays as tiles or large panels which are assembled in position for a specific entertainment show or event, or also as an architectural or advertising display. Examples of such systems are disclosed in U.S. Patent Nos.: 6,813,853, 6,704,989 and 6,314,669.
  • a display apparatus constructed as a large panel or as a series of solid tiles bolted or permanently fixed together may be very inappropriate for such an application or need.
  • the displays may be large and heavy, and require abundant support machinery, time, and storage space for installation.
  • an electronic signal display system requires the individual display sections be lifted out of storage cases with a lifting truss and then joined and stacked appropriately for display.
  • Tokimoto discloses a system that effectively integrates the electronic and structural components for use in a building.
  • the LED ribs are incorporated into a void in the glass wall of the building.
  • the system disclosed by Tokimoto could be used to back light a graphic on the glass exterior; however, issues with line of sight would prevent the system from acting as a part of the graphic. This may be the result in the alignment of the system and the graphic shifting as the viewer moves. Further, the system may not function as a finished surface and may be difficult to access and maintain.
  • the power supply unit may be easily integrated into the display system itself.
  • a panel display system such as an LED video panel display
  • Including the power supply unit into the panel may then increase the size of the display system, but this increase may be minimal for smaller display systems.
  • the addition of a power supply unit into the display system may significantly increase the size of the system and decrease the transparency and seamless integration of the system into the architectural structure.
  • larger display systems used for architectural purposes may have an exterior and/or outdoor installation with respect to the architectural structure. If the power supply unit is installed adjacent to the display system, the power supply unit may then not be easily accessible, such as by having the power supply unit on the exterior of the architectural structure. Alternatively, if not located adjacent the display system, the power supply unit may end up within a junction box or isolated room to protect the power supply unit. In this case, the power supply unit may still be remote and isolated from the display systems, thereby increasing difficulty if the power supply units require voltage regulation and adjustment. Accordingly, there exists a need for an apparatus and/or method to supply power that improves upon these prior art methods for continued development and success within the light emitting industry, in addition to any industry that may benefit from a more seamlessly integrated power supply unit.
