Abstract
This invention provides a light emitting array apparatus for use in a video screen display or lighting device incorporating a panel having a plurality of LEDs. Such a panel provides a plurality of LEDs on the front face of the panel in close thermal proximity to the panel. Typically this would include LEDs mounted to a PCB that is then affixed to the panel such that heat may transfer from the LEDs into the support panel itself. The support panel can disperse the heat throughout the panel and the to the surrounding air, especially from the front face of the panel. Such a construction may alleviate the need for fans or other cooling apparatus behind the panel and allow for the panel to be fitted directly to a supporting wall or other structure and also reduce cost and bulk of construction.
